Diesel Particulate FilterThe Duramax engine is equippedwith a Diesel Particulate Filter (DPF)that will filter or trap particulates.The DPF is under the vehicle in theexhaust system.

Depending on a number of factorsmonitored by the engine computer,the DPF will need to be cleaned ofaccumulated solids. When acleaning is needed, the enginecomputer will initiate a cleaningaction by warming the exhaust gastemperature. This feature has beendesigned to operate automatically,with limited operator involvement orawareness.

Noise may be heard at low speedswhen the emission controls areactive. This is normal.

Manual Regeneration of DieselParticulate Filter

If equipped, this feature allows formanual cleaning/regeneration of theDPF when it is unable to cleanitself. It may be necessary toperform a manual regeneration ifdriving conditions — such asextended slow speed, stop-and-gotraffic, extended idles, short drivecycles, or stationary PTOoperation — prevent DPFself-cleaning.

Manual regeneration can only beused when the DPF has become atleast 90% full. At 100% full, it willattempt to automatically self-clean ifproper driving conditions are met.The DPF will clean itself if thevehicle can be driven above50 km/h (30 mph) for about30 minutes.

A Driver Information Center (DIC)message displays when manualregeneration is possible.

Scroll through the DIC pages to findthe Exhaust Filter menu. Dependingon whether the vehicle has a baseor uplevel cluster, it may be underthe Options menu.

If the vehicle cannot be stoppedwhen the DIC message firstindicates cleaning is available,automatic self-cleaning may havebegun. If conditions cannot be metfor self-cleaning to complete, andmanual regeneration is selected, itmay take up to four minutes for thesystem to switch to manualregeneration. When the switchoccurs, a DIC message prompts tostart the cleaning process.

{ Warning

Do not leave the vehicle duringthe regeneration.

Make sure that there are noflammables near the muffler, DPFand exhaust pipe which mayresult in a fire.

26 In Brief

Warning (Continued)

Remember that the temperatureof exhaust gases is high enoughto burn you. You and others couldbe seriously injured.

Before starting the manualregeneration, make sure all of thefollowing safety conditions are met:

. The vehicle is parked on levelground, away from anyflammable materials.

. The vehicle is parked outdoors,away from any walls orbuildings.

. The vehicle is at least 3 m (10 ft)from any obstructions ormaterials that may combustor melt.

. The shift lever is in P (Park).

. The fuel tank is at leastone-eighth full.

. All fluids are at the proper level.

. No diagnostic trouble codeshave been set, and themalfunction indicator lamp isnot on.

. The engine coolant temperatureis above 71 °C (160 °F).

After making sure all of the safetyconditions have been met, press thetrip odometer reset stem or@ onthe steering wheel control for atleast one second to select Start onthe DIC.

Follow the instructions in the DICmessages. Choose ACCEPT toacknowledge that all of these safetyconditions have been met and toactivate regeneration.

If the DIC returns to the previousscreen, then one or more of thenecessary operating conditions hasnot been met.

Continue to follow the instructions inthe DIC messages. Hold theExhaust Brake switch on theinstrument panel below the climatecontrols for more thanthree seconds, and then release it,to begin the regeneration process.

If the EXHAUST BRAKE ONmessage displays, then the switchwas released too soon. Press itagain to turn off the exhaust brake,then try again when the DICmessage prompts.

When manual regeneration begins,the engine speed increases, theengine cooling fan sound increases,and a DIC message indicates thatcleaning is in progress.

A DIC message will display whencleaning has completed. Themessage will remain as long ascleaning is not necessary. Cleaningcould take up to 30 minutes. Uponcompletion, the engine will return tonormal idle, but exhaustcomponents will remain hot forseveral minutes. Do not move thevehicle until the exhaust has hadtime to cool. Manual regenerationcan be canceled at any time bypressing the brake pedal or turningthe engine off. Unusual noises maybe heard if regeneration isinterrupted.

In Brief 27

Cleaning the DPF (ExhaustFilter)

While the DPF cleaning isautomatically controlled by theengine computer, the DriverInformation Center (DIC) maydisplay a message. The vehicle willneed to operate continuously untilthe message is no longer displayed.Cleaning occurs above50 km/h (30 mph). If the vehicle isreturned to idle during the cleaningprocess, the driver may notice aslightly different sound or a slightlyelevated engine idle speed. This isnormal. No action is required on thepart of the driver during a regularDPF cleaning. See DieselParticulate Filter 0 217.

Special DPF Driver Messages

If the vehicle is used for numerousshort trips or extended slow-speedoperation, the engine computer maynot be able to adequately heat upthe exhaust system to clean theDPF effectively. The enginecomputer has been designed tocontinuously monitor the condition

of the DPF. When the enginecomputer detects that the DPF isnearly full of particulates and thatthe vehicle is not being operated ina manner that would allow effectiveautomatic DPF cleaning, the DICwill display a message.

If the vehicle continues to be drivenin a manner that prevents effectiveDPF cleaning, the DPF will becomeplugged with particulates. If thisoccurs, the engine computer willturn on the malfunction indicatorlamp (Check Engine Light) in theinstrument cluster, and the DIC willdisplay the message ENGINEPOWER IS REDUCED. See DieselParticulate Filter 0 217.

Fuel

Use Ultra Low Sulfur DieselFuel (ULSD)

Use ULSD only. The emissioncontrol hardware used on thevehicle may be damaged by usingfuel with high sulfur levels. Use onlyfuel that is dispensed from pumpsbearing the ULSD label.

Do Not Use Low Sulfur DieselFuel (LSD)

Do not use fuel that is dispensedfrom pumps bearing the LSD label.

Do Not Use Non-Highway Fuel

Fuel labeled as off road ornon-highway is typically very high insulfur content and will damage theemission control system.Non-highway fuel is not intended foruse in on-highway vehicles anddoes not have the fuel propertiesneeded by the DPF-equippedDuramax diesel.

In addition:

. Use the correct engine oil.

. Do not add gasoline todiesel fuel.

. Do not modify the induction orexhaust systems.

Diesel Exhaust FluidDiesel Exhaust Fluid (DEF) is usedwith diesel engines to reduce theamount of regulated emissionsproduced. The DEF system must bemaintained for the vehicle to runproperly.

DEF is not a fuel additive. Forrefilling instructions, see DieselExhaust Fluid 0 220. DEF shouldnot be mixed with or added to dieselfuel. DEF freezes when exposed totemperatures below −11 °C (12 ° F).

Locating Diesel Exhaust Fluid

DEF can be purchased at yourdealer. It can also be purchased atauthorized vehicle and truckdealerships. Additionally, somediesel truck fueling stations orretailers may have DEF forpurchase. For vehicles with anactive OnStar or connected serviceplan, OnStar can help to locate aDEF retailer. See RecommendedFluids and Lubricants 0 398.

As the DEF tank becomes low onfluid, the Driver Information Center(DIC) will begin to display warningsto indicate the approximateremaining range. These warningswill increase as the tank becomesempty. Once the tank is empty,vehicle speed will be limited. If thereis an issue with the quality of thefluid or the DEF system, the DIC willdisplay warnings. See DieselExhaust Fluid 0 220.

Seat BeltsThis section describes how to useseat belts properly, and some thingsnot to do.

{ Warning

Do not let anyone ride where aseat belt cannot be worn properly.In a crash, if you or yourpassenger(s) are not wearingseat belts, injuries can be muchworse than if you are wearingseat belts. You can be seriouslyinjured or killed by hitting thingsinside the vehicle harder or bybeing ejected from the vehicle. Inaddition, anyone who is notbuckled up can strike otherpassengers in the vehicle.

It is extremely dangerous to ridein a cargo area, inside or outsideof a vehicle. In a collision,passengers riding in these areasare more likely to be seriouslyinjured or killed. Do not allow

passengers to ride in any area ofthe vehicle that is not equippedwith seats and seat belts.

Always wear a seat belt, andcheck that all passenger(s) arerestrained properly too.

This vehicle has indicators as areminder to buckle the seat belts.See Seat Belt Reminders 0 111.

Why Seat Belts Work

When riding in a vehicle, you travelas fast as the vehicle does. If thevehicle stops suddenly, you keepgoing until something stops you.It could be the windshield, theinstrument panel, or the seat belts!

When you wear a seat belt, you andthe vehicle slow down together.There is more time to stop becauseyou stop over a longer distance and,when worn properly, your strongestbones take the forces from the seatbelts. That is why wearing seat beltsmakes such good sense.

Questions and Answers AboutSeat Belts

Q: Will I be trapped in the vehicleafter a crash if I am wearing aseat belt?

A: You could be— whether you arewearing a seat belt or not. Yourchance of being consciousduring and after a crash, so youcan unbuckle and get out, ismuch greater if you are belted.

. Always use the correct bucklefor your seating position.

. Wear the lap part of the belt lowand snug on the hips, justtouching the thighs. In a crash,

this applies force to the strongpelvic bones and you would beless likely to slide under the lapbelt. If you slid under it, the beltwould apply force on yourabdomen. This could causeserious or even fatal injuries.

. Wear the shoulder belt over theshoulder and across the chest.These parts of the body are bestable to take belt restrainingforces. The shoulder belt locks ifthere is a sudden stop or crash.

Before a door is closed, be sure theseat belt is out of the way. If a dooris slammed against a seat belt,damage can occur to both the seatbelt and the vehicle.

Shoulder Belt Height Adjuster

The vehicle has a shoulder beltheight adjuster for the driver andfront outboard passenger seatingpositions.

Adjust the height so the shoulderportion of the belt is on the shoulderand not falling off of it. The beltshould be close to, but notcontacting, the neck. Impropershoulder belt height adjustmentcould reduce the effectiveness ofthe seat belt in a crash. See How toWear Seat Belts Properly 0 54.

Push down on the release button tomove the height adjuster to thedesired position.

Move the adjuster up by pushing upon the shoulder belt guide.

After the adjuster is set to thedesired position, try to move it downwithout pushing the release buttonto make sure it has locked intoposition.

Seat Belt Pretensioners

This vehicle has seat beltpretensioners for the driver and frontoutboard passenger, if equippedwith a front outboard passengerseat. Although the seat beltpretensioners cannot be seen, theyare part of the seat belt assembly.They can help tighten the seat beltsduring the early stages of amoderate to severe frontal, nearfrontal, or rear crash if the thresholdconditions for pretensioneractivation are met.

Pretensioners work only once. If thepretensioners activate in a crash,the pretensioners and probablyother parts of the vehicle's seat belt

system will need to be replaced.See Replacing Seat Belt SystemParts after a Crash 0 60.

Do not sit on the outboard seat beltwhile entering or exiting the vehicleor at any time while sitting in theseat. Sitting on the seat belt candamage the webbing and hardware.

Rear Seat Belt Comfort Guides

Rear seat belt comfort guides mayprovide added seat belt comfort forolder children who have outgrownbooster seats and for some adults.When installed on a shoulder belt,the comfort guide positions theshoulder belt away from the neckand head.

Comfort guides are availablethrough your dealer for the rearoutboard seating positions.Instructions are included with theguide.

Seat Belt Use DuringPregnancySeat belts work for everyone,including pregnant women. Like alloccupants, they are more likely tobe seriously injured if they do notwear seat belts.

A pregnant woman should wear alap-shoulder belt, and the lapportion should be worn as low aspossible, below the rounding,throughout the pregnancy.

The best way to protect the fetus isto protect the mother. When a seatbelt is worn properly, it is more likely

that the fetus will not be hurt in acrash. For pregnant women, as foranyone, the key to making seatbelts effective is wearing themproperly.

Lap BeltThis section is only for the lap belt.To learn how to wear a lap-shoulderbelt, see Lap-Shoulder Belt 0 56.

The vehicle may have a centerseating position with a lap seat belt.The lap seat belt does not have aretractor.

To make the belt longer, tilt the latchplate and pull it along the belt.

Buckle, position, and release it thesame way as the lap part of alap-shoulder belt.

To make the belt shorter, pull its freeend as shown until the belt is snug.

If the belt is not long enough, seeSeat Belt Extender 0 59.

Make sure the release button on thebuckle is positioned so you wouldbe able to unbuckle the seat beltquickly if necessary.

Seat Belt ExtenderIf the vehicle's seat belt will fastenaround you, you should use it.

But if a seat belt is not long enough,your dealer will order you anextender. When you go in to order it,take the heaviest coat you will wear,so the extender will be long enoughfor you. To help avoid personalinjury, do not let someone else useit, and use it only for the seat it ismade to fit. The extender has beendesigned for adults. Never use it forsecuring child restraints. For moreinformation on the proper use and fitof seat belt extenders see theinstruction sheet that comes withthe extender.

New parts and repairs may benecessary even if the seat beltsystem was not being used at thetime of the crash.

Have the seat belt pretensionerschecked if the vehicle has been in acrash, or if the airbag readiness lightstays on after you start the vehicleor while you are driving. See AirbagReadiness Light 0 111.

Airbag SystemThe vehicle has the followingairbag:

. A frontal airbag for the driver.

The vehicle may have the followingairbag:

. A frontal airbag for the frontoutboard passenger.

For frontal airbags, the wordAIRBAG is on the center of thesteering wheel for the driver and onthe instrument panel for the frontoutboard passenger.

Airbags are designed to supplementthe protection provided by seatbelts. Even though today’s airbagsare also designed to help reducethe risk of injury from the force of aninflating airbag, all airbags mustinflate very quickly to do their job.

Here are the most important thingsto know about the airbag system:

{ Warning

You can be severely injured orkilled in a crash if you are notwearing your seat belt, even withairbags. Airbags are designed towork with seat belts, not replacethem. Also, airbags are notdesigned to inflate in every crash.In some crashes seat belts arethe only restraint. See WhenShould an Airbag Inflate? 0 63.

Wearing your seat belt during acrash helps reduce your chanceof hitting things inside the vehicleor being ejected from it. Airbagsare “supplemental restraints” tothe seat belts. Everyone in thevehicle should wear a seat beltproperly, whether or not there isan airbag for that person.

62 Seats and Restraints

{ Warning

Because airbags inflate with greatforce and faster than the blink ofan eye, anyone who is upagainst, or very close to anyairbag when it inflates can beseriously injured or killed. Do notsit unnecessarily close to anyairbag, as you would be if sittingon the edge of the seat or leaningforward. Seat belts help keep youin position before and during acrash. Always wear a seat belt,even with airbags. The drivershould sit as far back as possiblewhile still maintaining control ofthe vehicle. The seat belts andthe front outboard passengerairbag(s) are most effective whenyou are sitting well back andupright in the seat with both feeton the floor.

{ Warning

Children who are up against,or very close to, any airbag whenit inflates can be seriously injuredor killed. Always secure childrenproperly in the vehicle. To readhow, see Older Children 0 69 orInfants and Young Children 0 71.

There is an airbag readiness lighton the instrument panel, whichshows the airbag symbol.

The system checks the airbagelectrical system for malfunctions.The light tells you if there is anelectrical problem. See AirbagReadiness Light 0 111.

Where Are the Airbags?

The driver frontal airbag is in thecenter of the steering wheel.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Seats and Restraints 63

If the vehicle has a front outboardpassenger frontal airbag, it is in thepassenger side instrument panel.

{ Warning

If something is between anoccupant and an airbag, theairbag might not inflate properlyor it might force the object intothat person causing severe injuryor even death. The path of aninflating airbag must be keptclear. Do not put anythingbetween an occupant and an

Warning (Continued)

airbag, and do not attach or putanything on the steering wheelhub or on or near any otherairbag covering.

When Should an AirbagInflate?This vehicle is equipped with one ormore airbags. See Airbag System0 61. Airbags are designed to inflateif the impact exceeds the specificairbag system's deploymentthreshold. Deployment thresholdsare used to predict how severe acrash is likely to be in time for theairbags to inflate and help restrainthe occupants. The vehicle haselectronic sensors which help theairbag system determine theseverity of the impact. Deploymentthresholds can vary with specificvehicle design.

Frontal airbags are designed toinflate in moderate to severe frontalor near-frontal crashes to help

reduce the potential for severeinjuries mainly to the driver’s or frontoutboard passenger’s head andchest.

Whether the frontal airbags will orshould inflate is not based primarilyon how fast the vehicle is traveling.It depends on what is hit, thedirection of the impact, and howquickly the vehicle slows down.

Frontal airbags may inflate atdifferent crash speeds depending onwhether the vehicle hits an objectstraight on or at an angle, andwhether the object is fixed ormoving, rigid or deformable, narrowor wide.

Frontal airbags are not intended toinflate during vehicle rollovers, rearimpacts, or in many side impacts.

In any particular crash, no one cansay whether an airbag should haveinflated simply because of thevehicle damage or repair costs.

64 Seats and Restraints

What Makes an AirbagInflate?In a deployment event, the sensingsystem sends an electrical signaltriggering a release of gas from theinflator. Gas from the inflator fills theairbag causing the bag to break outof the cover. The inflator, the airbag,and related hardware are all part ofthe airbag module.

For airbag locations, see Where Arethe Airbags? 0 62.

How Does an AirbagRestrain?In moderate to severe frontal ornear frontal collisions, even beltedoccupants can contact the steeringwheel or the instrument panel. Inmoderate to severe side collisions,even belted occupants can contactthe inside of the vehicle.

Airbags supplement the protectionprovided by seat belts bydistributing the force of the impactmore evenly over theoccupant's body.

But airbags would not help in manytypes of collisions, primarilybecause the occupant's motion isnot toward those airbags. See WhenShould an Airbag Inflate? 0 63.

Airbags should never be regardedas anything more than a supplementto seat belts.

What Will You See afteran Airbag Inflates?After a frontal airbag inflates, itquickly deflates, so quickly thatsome people may not even realizethe airbag inflated. Somecomponents of the airbag modulemay be hot for several minutes. Forlocation of the airbags, see WhereAre the Airbags? 0 62.

The parts of the airbag that comeinto contact with you may be warm,but not too hot to touch. There maybe some smoke and dust comingfrom the vents in the deflatedairbags. Airbag inflation does notprevent the driver from seeing out of

the windshield or being able to steerthe vehicle, nor does it preventpeople from leaving the vehicle.

{ Warning

When an airbag inflates, theremay be dust in the air. This dustcould cause breathing problemsfor people with a history ofasthma or other breathing trouble.To avoid this, everyone in thevehicle should get out as soon asit is safe to do so. If you havebreathing problems but cannotget out of the vehicle after anairbag inflates, then get fresh airby opening a window or a door.If you experience breathingproblems following an airbagdeployment, you should seekmedical attention.

The vehicle has a feature that mayautomatically unlock the doors (ifequipped with power door locks),turn on the interior lamps andhazard warning flashers, and shutoff the fuel system after the airbags

inflate. The feature may alsoactivate, without airbag inflation,after an event that exceeds apredetermined threshold. Afterturning the ignition off and then onagain, the fuel system will return tonormal operation; the doors can belocked, the interior lamps can beturned off, and the hazard warningflashers can be turned off using thecontrols for those features. If any ofthese systems are damaged in thecrash they may not operate asnormal.

{ Warning

A crash severe enough to inflatethe airbags may have alsodamaged important functions inthe vehicle, such as the fuelsystem, brake and steeringsystems, etc. Even if the vehicleappears to be drivable after amoderate crash, there may beconcealed damage that couldmake it difficult to safely operatethe vehicle.

(Continued)

Warning (Continued)

Use caution if you should attemptto restart the engine after a crashhas occurred.

In many crashes severe enough toinflate the airbag, windshields arebroken by vehicle deformation.Additional windshield breakage mayalso occur from the front outboardpassenger airbag.

. Airbags are designed to inflateonly once. After an airbaginflates, you will need some newparts for the airbag system.If you do not get them, theairbag system will not be thereto help protect you in anothercrash. A new system will includeairbag modules and possiblyother parts. The service manualfor the vehicle covers the needto replace other parts.

This switch should only be turned tothe OFF position if the person in thefront outboard passenger position isa member of a passenger risk groupidentified by the nationalgovernment as follows:

Infant. An infant (less than1 year old) must ride in the frontseat because:

. My vehicle has no rear seat;

. My vehicle has a rear seat toosmall to accommodate arear-facing infant seat; or

. The infant has a medicalcondition which, according to theinfant's physician, makes itnecessary for the infant to ride inthe front seat so that the drivercan constantly monitor thechild's condition.

Child age 1 to 12. A childage 1 to 12 must ride in the frontseat because:

. My vehicle has no rear seat;

. Although children ages 1 to 12ride in the rear seat(s) wheneverpossible, children ages 1 to 12

sometimes must ride in the frontbecause no space is available inthe rear seat(s) of my vehicle; or

Child Restraints

Older Children

Older children who have outgrownbooster seats should wear thevehicle’s seat belts.

The manufacturer instructions thatcome with the booster seat state theweight and height limitations for thatbooster. Use a booster seat with alap-shoulder belt until the childpasses the fit test below:

. Sit all the way back on the seat.Do the knees bend at the seatedge? If yes, continue. If no,return to the booster seat.

. Buckle the lap-shoulder belt.Does the shoulder belt rest onthe shoulder? If yes, continue.If no, try using the rear seat beltcomfort guide, if available. See“Rear Seat Belt Comfort Guides”under Lap-Shoulder Belt 0 56.If a comfort guide is notavailable, or if the shoulder beltstill does not rest on theshoulder, then return to thebooster seat.

. Does the lap belt fit low andsnug on the hips, touching thethighs? If yes, continue. If no,return to the booster seat.

70 Seats and Restraints. Can proper seat belt fit be

maintained for the length of thetrip? If yes, continue. If no,return to the booster seat.

If you have the choice, a childshould sit in a position with alap-shoulder belt and get theadditional restraint a shoulderbelt can provide.

Q: What is the proper way towear seat belts?

A: An older child should wear alap-shoulder belt and get theadditional restraint a shoulderbelt can provide. The shoulderbelt should not cross the face orneck. The lap belt should fitsnugly below the hips, justtouching the top of the thighs.This applies belt force to thechild's pelvic bones in a crash.It should never be worn over theabdomen, which could causesevere or even fatal internalinjuries in a crash.

Also see “Rear Seat Belt ComfortGuides” under Lap-Shoulder Belt0 56.

According to accident statistics,children are safer when properlyrestrained in a rear seating position.

In a crash, children who are notbuckled up can strike other peoplewho are buckled up, or can bethrown out of the vehicle. Olderchildren need to use seat beltsproperly.

{ Warning

Never allow more than one childto wear the same seat belt. Theseat belt cannot properly spreadthe impact forces. In a crash, theycan be crushed together andseriously injured. A seat belt mustbe used by only one person ata time.

{ Warning

Never allow a child to wear theseat belt with the shoulder beltbehind their back. A child can beseriously injured by not wearingthe lap-shoulder belt properly. In acrash, the child would not berestrained by the shoulder belt.The child could move too farforward increasing the chance ofhead and neck injury. The childmight also slide under the lapbelt. The belt force would then beapplied right on the abdomen.

need, for everyone, to use safetyrestraints. In fact, the law in everystate in the United States and inevery Canadian province sayschildren up to some age must berestrained while in a vehicle.

{ Warning

Children can be seriously injuredor strangled if a shoulder belt iswrapped around their neck. Theshoulder belt can tighten butcannot be loosened if it is locked.The shoulder belt locks when it ispulled all the way out of theretractor. It unlocks when theshoulder belt is allowed to go allthe way back into the retractor,but it cannot do this if it iswrapped around a child’s neck.If the shoulder belt is locked andtightened around a child’s neck,the only way to loosen the belt isto cut it.

or killed. Never put a rear-facingchild restraint in the frontoutboard seat. Secure arear-facing child restraint in a rearseat. It is also better to secure aforward-facing child restraint in arear seat. If you must secure aforward-facing child restraint inthe front outboard seat, alwaysmove the front passenger seat asfar back as it will go.

Child restraints are devices used torestrain, seat, or position children inthe vehicle and are sometimescalled child seats or car seats.

There are three basic types ofchild restraints:

. Forward-facing child restraints

. Rear-facing child restraints

. Belt-positioning booster seats

The proper child restraint for yourchild depends on their size, weight,and age, and also on whether thechild restraint is compatible with thevehicle in which it will be used.

For each type of child restraint,there are many different modelsavailable. When purchasing a childrestraint, be sure it is designed to beused in a motor vehicle. If it is, therestraint will have a label saying thatit meets federal motor vehicle safetystandards. The restraintmanufacturer's instructions thatcome with the restraint state theweight and height limitations for aparticular child restraint. In addition,

there are many kinds of restraintsavailable for children with specialneeds.

{ Warning

To reduce the risk of neck andhead injury in a crash, infants andtoddlers should be secured in arear-facing child restraint until agetwo, or until they reach themaximum height and weight limitsof their child restraint.

{ Warning

A young child's hip bones are stillso small that the vehicle's regularseat belt may not remain low onthe hip bones, as it should.Instead, it may settle up aroundthe child's abdomen. In a crash,the belt would apply force on abody area that is unprotected byany bony structure. This alonecould cause serious or fatal

Child Restraint Systems

Rear-Facing Infant Restraint

A rear-facing child restraint providesrestraint with the seating surfaceagainst the back of the infant.

The harness system holds the infantin place and, in a crash, acts tokeep the infant positioned in therestraint.

Forward-Facing Child Restraint

A forward-facing child restraintprovides restraint for the child'sbody with the harness.

Booster Seats

A belt-positioning booster seat isused for children who haveoutgrown their forward-facing childrestraint. Boosters are designed toimprove the fit of the vehicle's seatbelt system until the child is largeenough for the vehicle seat belts tofit properly without a booster seat.See the seat belt fit test in OlderChildren 0 69.

Securing an Add-On ChildRestraint in the Vehicle

{ Warning

A child can be seriously injured orkilled in a crash if the childrestraint is not properly secured inthe vehicle. Secure the childrestraint properly in the vehicleusing the vehicle’s seat belt orLATCH system, following theinstructions that came with thatchild restraint and the instructionsin this manual.

To help reduce the chance of injury,the child restraint must be securedin the vehicle. Child restraints mustbe secured in vehicle seats by lapbelts or the lap belt portion of alap-shoulder belt, or by the LATCHsystem. See Lower Anchors andTethers for Children (LATCHSystem) 0 76 for more information.Children can be endangered in acrash if the child restraint is notproperly secured in the vehicle.

When securing an add-on childrestraint, refer to the instructionsthat come with the restraint whichmay be on the restraint itself or in abooklet, or both, and to this manual.The child restraint instructions areimportant, so if they are notavailable, obtain a replacementcopy from the manufacturer.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle— even when no child isin it.

In some areas of the United Statesand Canada, Certified ChildPassenger Safety Technicians(CPSTs) are available to inspectand demonstrate how to correctlyuse and install child restraints. Inthe U.S., refer to the NationalHighway Traffic SafetyAdministration (NHTSA) website tolocate the nearest child safety seatinspection station. For CPST

Securing the Child Within theChild Restraint

{ Warning

A child can be seriously injured orkilled in a crash if the child is notproperly secured in the childrestraint. Secure the childproperly following the instructionsthat came with that child restraint.

Where to Put theRestraintAccording to accident statistics,children and infants are safer whenproperly restrained in an appropriatechild restraint secured in a rearseating position.

Whenever possible, children aged12 and under should be secured ina rear seating position.

Never put a rear-facing childrestraint in the front. This is becausethe risk to the rear-facing child is sogreat if the airbag deploys.

If a child restraint is secured in thefront outboard passenger seat andthe vehicle has a switch on theinstrument panel endcap tomanually turn off the front outboardpassenger airbag, see AirbagOn-Off Switch 0 65 and SecuringChild Restraints (With the Seat Beltin the Center Front Seat) 0 87 orSecuring Child Restraints (With theSeat Belt in the Rear Seat) 0 85 orSecuring Child Restraints (With theSeat Belt in the Front Seat) 0 88 formore information, includingimportant safety information.

be very close to the inflatingairbag. A child in a forward-facingchild restraint can be seriouslyinjured or killed if the frontoutboard passenger airbaginflates and the passenger seat isin a forward position.

Even if the airbag switch hasturned off the front outboardpassenger frontal airbag, nosystem is fail-safe. No one canguarantee that an airbag will notdeploy under some unusualcircumstance, even though it isturned off.

Secure rear-facing child restraintsin a rear seat, even if the airbagis off. If you secure aforward-facing child restraint inthe front outboard passengerseat, always move the seat as farback as it will go. It is better tosecure the child restraint in arear seat.

{ Warning

A child in a child restraint in thecenter front seat can be badlyinjured or killed by the frontalairbags if they inflate. Neversecure a child restraint in thecenter front seat. It is alwaysbetter to secure a child restraint ina rear seat.

Do not use child restraints in thecenter front seat position.

If the vehicle does not have a rearseat that will accommodate arear-facing child restraint, arear-facing child restraint should notbe installed in the vehicle, even ifthe airbag is off.

When securing a child restraint withthe seat belts in a rear seat position,study the instructions that came withthe child restraint to make sure it iscompatible with this vehicle.

Child restraints and booster seatsvary considerably in size, and somemay fit in certain seating positionsbetter than others.

Depending on where you place thechild restraint and the size of thechild restraint, you may not be ableto access adjacent seat belts orLATCH anchors for additionalpassengers or child restraints.Adjacent seating positions shouldnot be used if the child restraintprevents access to or interferes withthe routing of the seat belt.

Wherever a child restraint isinstalled, be sure to follow theinstructions that came with the childrestraint and secure the childrestraint properly.

Keep in mind that an unsecuredchild restraint can move around in acollision or sudden stop and injurepeople in the vehicle. Be sure toproperly secure any child restraint inthe vehicle — even when no child isin it.

Lower Anchors andTethers for Children(LATCH System)The LATCH system secures a childrestraint during driving or in a crash.LATCH attachments on the childrestraint are used to attach the childrestraint to the anchors in thevehicle. This system is designed tomake installation of a child restrainteasier.

In order to use the LATCH system inyour vehicle, you need a childrestraint that has LATCHattachments. LATCH-compatiblerear-facing and forward-facing childseats can be properly installedusing either the LATCH anchors orthe vehicle’s seat belts. Do not useboth the seat belts and the LATCHanchorage system to secure arear-facing or forward-facingchild seat.

Booster seats use the vehicle’s seatbelts to secure the child in thebooster seat. If the manufacturerrecommends that the booster seatbe secured with the LATCH system,

this can be done as long as thebooster seat can be positionedproperly and there is no interferencewith the proper positioning of thelap-shoulder belt on the child.

Make sure to follow the instructionsthat came with the child restraint,and also the instructions in thismanual.

When installing a child restraint witha top tether, you must also useeither the lower anchors or the seatbelts to properly secure the childrestraint. A child restraint mustnever be attached using only the toptether.

The LATCH anchorage system canbe used until the combined weightof the child plus the child restraint is29.5 kg (65 lbs). Use the seat beltalone instead of the LATCHanchorage system once thecombined weight is more than29.5 kg (65 lbs).

See Securing Child Restraints (Withthe Seat Belt in the Center FrontSeat) 0 87 or Securing ChildRestraints (With the Seat Belt in theRear Seat) 0 85 or Securing ChildRestraints (With the Seat Belt in theFront Seat) 0 88.

Child restraints built after March2014 will be labeled with thespecific child weight up to which theLATCH system can be used toinstall the restraint.

The following explains how to attacha child restraint with theseattachments in the vehicle.

Not all vehicle seating positions orchild restraints have lower anchorsand attachments or top tetheranchors and attachments. In thiscase, the seat belt must be used(with top tether where available) tosecure the child restraint.See Securing Child Restraints (Withthe Seat Belt in the Center FrontSeat) 0 87 or Securing ChildRestraints (With the Seat Belt in theRear Seat) 0 85 or Securing ChildRestraints (With the Seat Belt in theFront Seat) 0 88.

Lower Anchors

Lower anchors (1) are metal barsbuilt into the vehicle. There are twolower anchors for each LATCHseating position that willaccommodate a child restraint withlower attachments (2).

Top Tether Anchor

A top tether (3, 4) is used to securethe top of the child restraint to thevehicle. A top tether anchor is builtinto the vehicle. The top tetherattachment hook (2) on the childrestraint connects to the top tetheranchor in the vehicle in order toreduce the forward movement androtation of the child restraint duringdriving or in a crash.

The child restraint may have asingle tether (3) or a dual tether (4).Either will have a single attachmenthook (2) to secure the top tether tothe anchor.

Some child restraints that have atop tether are designed for use withor without the top tether beingattached. Others require the toptether always to be attached. InCanada, the law requires thatforward-facing child restraints havea top tether, and that the tether beattached. Be sure to read and followthe instructions for your childrestraint.

Here are four things that someowners ask about. None of theseshow a problem with the fuel gauge:

. At the service station, the fuelpump shuts off before the gaugereads full.

. It takes a little more or less fuelto fill up than the gaugeindicated. For example, thegauge may have indicated thetank was half full, but it actuallytook a little more or less thanhalf the tank's capacity to fillthe tank.

. The gauge moves a little whileturning a corner or speeding up.

. The gauge takes a few secondsto stabilize after the ignition isturned on, and goes back toempty when the ignition isturned off.

Engine Oil PressureGauge

The engine oil pressure gaugeshows the engine oil pressurein psi (pounds per square inch)when the engine is running.

Oil pressure can vary with enginespeed, outside temperature, coolanttemperature, and oil viscosity.

On some models, the oil pump willvary engine oil pressure accordingto engine needs. Oil pressure maychange quickly as the engine speedor load varies. This is normal. If theoil pressure warning light or Driver

Information Center (DIC) messageindicates oil pressure outside thenormal operating range, check thevehicle's oil as soon as possible.

See Engine Oil 0 295.

Caution

Lack of proper engine oilmaintenance can damage theengine. Driving with the engine oillow can also damage the engine.The repairs would not be coveredby the vehicle warranty. Checkthe oil level as soon as possible.Add oil if required, but if the oillevel is within the operating rangeand the oil pressure is still low,have the vehicle serviced. Alwaysfollow the maintenance schedulefor changing engine oil.

Engine CoolantTemperature Gauge

This gauge measures thetemperature of the vehicle's enginecoolant.

While driving under normaloperating conditions, if the needlemoves into the red warning area,the engine is too hot. Pull off theroad, stop the vehicle, and turn offthe engine as soon as possible.

Voltmeter Gauge

When the ignition is on, this gaugeindicates the battery voltage.

When the engine is running, thisgauge shows the condition of thecharging system. The gauge cantransition from a higher to lower or alower to higher reading. This isnormal. If the vehicle is operatingoutside the normal operating range,the charging system light comes on.See Charging System Light 0 113for more information. The voltmetergauge may also read lower when infuel economy mode. This is normal.

Readings outside the normaloperating range can also occurwhen a large number of electricalaccessories are operating in thevehicle and the engine is left idlingfor an extended period. Thiscondition is normal since thecharging system is not able toprovide full power at engine idle. Asengine speeds are increased, thiscondition should correct itself ashigher engine speeds allow thecharging system to create maximumpower.

The vehicle can only be driven for ashort time with the readings outsidethe normal operating range. If thevehicle must be driven, turn off allaccessories, such as the radio andair conditioner.

Readings outside the normaloperating range indicate a possibleproblem in the electrical system.Have the vehicle serviced as soonas possible.

on for a set amount of time and thenautomatically turn off. The interiorlamps do not come on if the domelamp control is in the Off position.

The exterior lamps turn offimmediately by turning the exteriorlamps control off.

This feature can be changed. SeeVehicle Personalization 0 124.

Battery LoadManagementThe vehicle has Electric PowerManagement (EPM), whichestimates the battery's temperatureand state of charge. It then adjuststhe voltage for best performanceand extended life of the battery.

When the battery's state of chargeis low, the voltage is raised slightlyto quickly bring the charge back up.When the state of charge is high,the voltage is lowered slightly toprevent overcharging. The voltmetergauge or the voltage display on theDriver Information Center (DIC),if equipped, may show the voltage

moving up or down. This is normal.If there is a problem, an alert will bedisplayed.

The battery can be discharged atidle if the electrical loads are veryhigh. This is true for all vehicles.This is because the generator(alternator) may not be spinning fastenough at idle to produce all thepower that is needed for very highelectrical loads.

A high electrical load occurs whenseveral of the following are on, suchas: headlamps, high beams, foglamps, rear window defogger,climate control fan at high speed,heated seats, engine cooling fans,trailer loads, and loads plugged intoaccessory power outlets.

EPM works to prevent excessivedischarge of the battery. It does thisby balancing the generator's outputand the vehicle's electrical needs.It can increase engine idle speed togenerate more power, wheneverneeded. It can temporarily reducethe power demands of someaccessories.

Normally, these actions occur insteps or levels, without beingnoticeable. In rare cases at thehighest levels of corrective action,this action may be noticeable to thedriver. If so, a DIC message mightbe displayed and it is recommendedthat the driver reduce the electricalloads as much as possible.

Battery Power ProtectionThis feature shuts off the dome andreading lamps, if they are left on formore than 10 minutes after theignition is turned off. The cargolamp shuts off after 20 minutes. Thisprevents the battery fromrunning down.

Exterior Lighting BatterySaverThe exterior lamps turn off about10 minutes after the ignition isturned off, if the parking lamps orheadlamps have been manually lefton. This protects against drainingthe battery. To restart the 10-minute

timer, turn the exterior lamp controlto the O position and then back to

the; or2 position.

To keep the lamps on for more than10 minutes, the ignition must be onor in ACC/ACCESSORY.

However, not all features withinthese areas are supported by voicecommands. Generally, only complextasks that require multiple manualinteractions to complete aresupported by voice commands.

For example, tasks that take morethan one or two button presses suchas selecting a song or artist to playfrom a media device would besupported by voice commands.Other tasks, like adjusting thevolume or seeking up or down areaudio features that are easilyperformed by pressing one or twobuttons, and are not supported byvoice commands.

168 Infotainment System

In general there are flexible ways tospeak commands for completing thetasks. Most of them, exceptdestination entry and voice keypad,can be completed in a singlecommand. If the task takes morethan one command to complete, thefirst command would be to indicatethe kind of task that is to beperformed. The system replies withprompts that lead through a dialogto enter the necessary information.

Voice recognition can be used whenthe ignition is on or when RetainedAccessory Power (RAP) is active.See Retained Accessory Power(RAP) 0 214.

Using Voice Recognition

Voice recognition becomes availableonce the system has beeninitialized. This begins when theignition is turned on. Initializationmay take a few moments.

1. Press g on the steering wheelcontrol to activate voicerecognition, or touch g on theinfotainment display.

. If voice recognition isstarted from the steeringwheel control, theinstrument cluster displaysthe selections and visualdialog content.

. If voice recognition isstarted from theinfotainment display, theselections and visual dialogcontent are displayed onboth the infotainmentdisplay and the instrumentcluster display.

2. The audio system mutes andthe system plays a promptfollowed by a beep.

3. Wait until after the beepcompletes, then clearly speakone of the commandsdescribed in this section.

Press g to interrupt any voicerecognition system prompt. Forexample, if the prompt seemsto be taking too long to finish,press g again and the beepshould happen right away.

There are two voice prompt modessupported:

. Long verbal prompts: The longerprompts provide moreinformation regarding thesupported actions.

. Short prompts: The shortprompts provide simpleinstructions about what can bestated.

If a command is not spoken, thevoice recognition system says ahelp prompt.

Prompts and Screen Displays

While a voice recognition session isactive, there will be correspondingbuttons on screens displayed.Manual interaction in the voicerecognition session is permitted.Interaction during a voice sessionmay be completed entirely using

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Infotainment System 169

voice commands, or someselections may expedite a session.If a selection is made using amanual control, the dialog willprogress in the same way as if theselection were made through avoice command. Once the system isable to complete the task, or thesession is terminated, the voicerecognition dialog stops.

An example of this type of manualintervention is touching an entry of adisplayed number list instead ofspeaking the number associatedwith the entry desired.

Canceling Voice Recognition

. Touch { to terminate the voicerecognition session that wasinitiated by touching g on theinfotainment display.

. Press or say “Cancel” or “Exit” toterminate the voice recognitionsession and display the screenfrom which voice recognitionwas initiated.

. Pressi on the steering wheelcontrols to terminate the voicesession and display the screenfrom which voice recognitionwas initiated.

Helpful Hints for SpeakingCommands

Voice recognition can understandcommands that are either naturallystated in sentence form (Englishonly), or direct commands that statethe application and the task.

For languages that do not supportnatural language commands insentence form, use the directcommands shown as examples onthe display screen.

For best results:

. Listen for the prompt and waitfor the beep before saying acommand or reply.

. Say “Help” or look at the screendisplay for commands.

. Voice recognition systemprompts can be interruptedduring a prompt by pressing gagain.

For example, if the promptseems to be taking too long tofinish, or if what is beingprompted causes a need for animmediate reply, press g againand wait for the beep.

. Speak the command naturally,not too fast, not too slow. Usedirect commands without a lot ofextra words.

. Usually Phone and Audiocommands can be spoken in asingle command; for example,“Call Dave Smith at work,” “Play”followed by the artist or songname, or “Tune” followed by theradio station number.

There is no need to memorizespecific command words. Directcommands might be more clearlyunderstood by the system. Anexample of a direct command wouldbe “Call 555-1212.” Examples ofthese direct commands are

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

170 Infotainment System

displayed on most of the screenswhile a voice session is active.If “Phone” or “Phone Commands,” isstated, the system understands thata phone call is requested and willrespond with questions until enoughdetails are gathered.

If the phone number has beensaved with a name and a place, thedirect command should includeboth, for example “Call Dave Smithat work.”

Using Voice Recognition forList Options

When a list is displayed, a voiceprompt will ask to confirm or selectan option from that list. A selectioncan be made by manually selectingthe item, or by speaking the linenumber for the item to select.

When a screen contains a list,options may be available but notdisplayed. The list on a voicerecognition screen functions thesame as a list on other screens.Scrolling can be used to helpdisplay other entries from the list.

Manually scrolling or paging the liston a screen during a voicerecognition session suspends thecurrent voice recognition event andplays the prompt “Make yourselection from the list using themanual controls or press the Backbutton to try again.”

If manual selection takes more than15 seconds, the session terminatesand prompts that it has timed out.The screen returns to the screenwhere voice recognition wasinitiated.

The Back Command

Say “Back” or press the Back buttonto go to the previous screen.

If in voice recognition, and “Back” isstated all the way through to theinitial screen, then “Back” is statedone more time, the voice recognitionsession will cancel.

Help

Say “Help” on any voice recognitionscreen and the help prompt for thescreen is played. Additionally, apop-up displays a text version of the

help prompt. Depending on howvoice recognition was initiated, theHelp pop-up will either display onthe instrument cluster or theinfotainment display. Touch Dismissto make the pop-up go away.

Pressing g while the help prompt isplaying will terminate the promptand a beep will be heard. Doing thiswill stop the help prompt so that avoice command can be used.

Voice Recognition for theRadio

Touch g on the infotainment displayto launch audio voice recognition.If g is touched in a radio screen, thevoice commands for radio andmedia features are available.

Handling Large Amounts of MediaContent

It is expected that large amounts ofmedia content will be brought intothe vehicle. It may be necessary tohandle large amounts of mediacontent in a different way than

smaller amounts of media. Thesystem may limit the options ofvoice recognition by not allowingselection of song titles by voice atthe highest level if the number ofsongs exceeds the maximum limit.

Voice command option changesthrough media content limits are:

. Song files including otherindividual files of all media typessuch as audiobook chapters,podcast episodes, and videos.

. Album type folders includingtypes such as albums andaudiobooks.

There are no restrictions if thenumber of song files and albums isless than 4,000. When the numberof song files connected to thesystem is between 4,000 and 8,000,the content cannot be accesseddirectly with one command like“Play <song name>.”

The restriction is that the command“Play Song” must be spoken first;the system will then ask for the songname. The reply command would beto say the name of the song to play.

Similar limits exist for albumcontent. If there are more than4,000 albums, but less than 8,000,the content cannot be accesseddirectly with one command like,“Play <album name>.” Thecommand “Play Album” must first bespoken; the system will then ask forthe album name. The reply wouldbe to say the name of the albumto play.

Once the number of songs hasexceeded approximately 8,000,there is no support for accessing thesongs directly through voicecommands. There will still beaccess to the media content byusing commands for playlists,artists, and genres.

The access commands for playlists,artists, and genres are prohibitedafter the number of this type ofmedia exceeds 4,000.

The system will provide feedbackthe first time voice recognition isinitiated if it has become apparentthat any of these limits are reachedduring a device initializing process.

Driving Information

Distracted DrivingDistraction comes in many formsand can take your focus from thetask of driving. Exercise goodjudgment and do not let otheractivities divert your attention awayfrom the road. Many localgovernments have enacted lawsregarding driver distraction. Becomefamiliar with the local laws inyour area.

To avoid distracted driving, keepyour eyes on the road, keep yourhands on the steering wheel, andfocus your attention on driving.

. Do not use a phone indemanding driving situations.Use a hands-free method toplace or receive necessaryphone calls.

. Watch the road. Do not read,take notes, or look upinformation on phones or otherelectronic devices.

. Designate a front seatpassenger to handle potentialdistractions.

. Become familiar with vehiclefeatures before driving, such asprogramming favorite radiostations and adjusting climatecontrol and seat settings.Program all trip information intoany navigation device prior todriving.

. Wait until the vehicle is parkedto retrieve items that have fallento the floor.

. Stop or park the vehicle to tendto children.

. Keep pets in an appropriatecarrier or restraint.

. Avoid stressful conversationswhile driving, whether with apassenger or on a cell phone.

194 Driving and Operating

{ Warning

Taking your eyes off the road toolong or too often could cause acrash resulting in injury or death.Focus your attention on driving.

Refer to the infotainment sectionand/or infotainment manual on usingthat system and the navigationsystem, if equipped, includingpairing and using a cell phone.

Defensive DrivingDefensive driving means “alwaysexpect the unexpected.” The firststep in driving defensively is to wearthe seat belt. See Seat Belts 0 53.

. Assume that other road users(pedestrians, bicyclists, andother drivers) are going to becareless and make mistakes.Anticipate what they might doand be ready.

. Allow enough following distancebetween you and the driver infront of you.

. Focus on the task of driving.

Drunk DrivingDeath and injury associated withdrinking and driving is a globaltragedy.

{ Warning

Drinking and then driving is verydangerous. Your reflexes,perceptions, attentiveness, andjudgment can be affected by evena small amount of alcohol. Youcan have a serious — or evenfatal — collision if you drive afterdrinking.

Do not drink and drive or ride witha driver who has been drinking.Ride home in a cab; or if you arewith a group, designate a driverwho will not drink.

Control of a VehicleBraking, steering, and acceleratingare important factors in helping tocontrol a vehicle while driving.

BrakingBraking action involves perceptiontime and reaction time. Deciding topush the brake pedal is perceptiontime. Actually doing it isreaction time.

Average driver reaction time isabout three-quarters of a second. Inthat time, a vehicle moving at100 km/h (60 mph) travels 20 m(66 ft), which could be a lot ofdistance in an emergency.

Helpful braking tips to keep in mindinclude:

. Keep enough distance betweenyou and the vehicle in frontof you.

. Avoid needless heavy braking.

. Keep pace with traffic.

If the engine ever stops while thevehicle is being driven, brakenormally but do not pump thebrakes. Doing so could make thepedal harder to push down. If theengine stops, there will be somepower brake assist but it will beused when the brake is applied.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Driving and Operating 195

Once the power assist is used up, itcan take longer to stop and thebrake pedal will be harder to push.

SteeringThe power steering system mayrequire maintenance. See PowerSteering Fluid 0 306.

If power steering assist is lostbecause the engine stops or thesystem malfunctions, the vehiclecan be steered but may requireincreased effort. See your dealer.

Caution

If the steering wheel is turneduntil it reaches the end of itstravel, and is held in that positionfor more than 15 seconds,damage may occur to the powersteering system and there may beloss of power steering assist.

Curve Tips. Take curves at a reasonable

speed.

. Reduce speed before entering acurve.

. Maintain a reasonable steadyspeed through the curve.

. Wait until the vehicle is out ofthe curve before acceleratinggently into the straightaway.

Steering in Emergencies. There are some situations when

steering around a problem maybe more effective than braking.

. Holding both sides of thesteering wheel allows you to turn180 degrees without removinga hand.

. Antilock Brake System (ABS)allows steering while braking.

Off-Road Recovery

The vehicle's right wheels can dropoff the edge of a road onto theshoulder while driving. Followthese tips:

1. Ease off the accelerator andthen, if there is nothing in theway, steer the vehicle so that itstraddles the edge of thepavement.

2. Turn the steering wheel aboutone-eighth of a turn, until theright front tire contacts thepavement edge.

196 Driving and Operating

3. Turn the steering wheel to gostraight down the roadway.

Loss of Control

Skidding

There are three types of skids thatcorrespond to the vehicle's threecontrol systems:

. Braking Skid — wheels are notrolling.

. Steering or Cornering Skid —too much speed or steering in acurve causes tires to slip andlose cornering force.

. Acceleration Skid — too muchthrottle causes the drivingwheels to spin.

Defensive drivers avoid most skidsby taking reasonable care suited toexisting conditions, and by notoverdriving those conditions. Butskids are always possible.

If the vehicle starts to slide, followthese suggestions:

. Ease your foot off theaccelerator pedal and steer theway you want the vehicle to go.The vehicle may straighten out.Be ready for a second skid if itoccurs.

. Slow down and adjust yourdriving according to weatherconditions. Stopping distancecan be longer and vehiclecontrol can be affected whentraction is reduced by water,snow, ice, gravel, or othermaterial on the road. Learn torecognize warning clues — suchas enough water, ice, or packedsnow on the road to make amirrored surface — and slowdown when you have any doubt.

. Try to avoid sudden steering,acceleration, or braking,including reducing vehicle speedby shifting to a lower gear. Anysudden changes could causethe tires to slide.

Remember: Antilock brakes helpavoid only the braking skid.

Off-Road DrivingFour-wheel-drive vehicles can beused for off-road driving. Vehicleswithout four-wheel drive andvehicles not equipped with AllTerrain (AT) or On-Off Road (OOR)tires must not be driven off-roadexcept on a level, solid surface. Forcontact information about theoriginal equipment tires, see thewarranty manual.

One of the best ways for successfuloff-road driving is to control thespeed.

{ Warning

When driving off-road, bouncingand quick changes in directioncan easily throw you out ofposition. This could cause you tolose control and crash. You andyour passengers should alwayswear seat belts.

Driving and Operating 197

Before Driving Off-Road. Have all necessary maintenance

and service work completed.

. Fuel the vehicle, fill fluid levels,and check inflation pressure inall tires, including the spare,if equipped.

. Read all the information aboutfour-wheel-drive vehicles in thismanual.

. Know the local laws that apply tooff-road driving.

To gain more ground clearance ifneeded, it may be necessary toremove the front fascia lower airdam, if equipped. However, drivingwithout the air dam reduces fueleconomy.

Caution

Operating the vehicle forextended periods without the frontfascia lower air dam installed cancause improper airflow to theengine. Reattach the front fasciaair dam after off-road driving.

Loading the Vehicle forOff-Road Driving

{ Warning

. Unsecured cargo on theload floor can be tossedabout when driving overrough terrain. You or yourpassengers can be struckby flying objects. Secure thecargo properly.

. Keep cargo in the cargoarea as far forward and aslow as possible. Theheaviest things should beon the floor, forward of therear axle.

. Heavy loads on the roofraise the vehicle's center ofgravity, making it more likelyto roll over. You can beseriously or fatally injured ifthe vehicle rolls over. Putheavy loads inside thecargo area, not on the roof.

For more information about loadingthe vehicle, see Vehicle Load Limits0 205 and Tires 0 331.

Environmental Concerns. Always use established trails,

roads, and areas that have beenset aside for public off-roadrecreational driving and obey allposted regulations.

. Do not damage shrubs, flowers,trees, or grasses or disturbwildlife.

. Do not park over things thatburn. See Parking over ThingsThat Burn 0 215.

Driving on Hills

Driving safely on hills requires goodjudgment and an understanding ofwhat the vehicle can and cannot do.

{ Warning

Many hills are simply too steepfor any vehicle. Driving up hillscan cause the vehicle to stall.

(Continued)

198 Driving and Operating

Warning (Continued)

Driving down hills can cause lossof control. Driving across hills cancause a rollover. You could beinjured or killed. Do not drive onsteep hills.

Before driving on a hill, assess thesteepness, traction, andobstructions. If the terrain aheadcannot be seen, get out of thevehicle and walk the hill beforedriving further.

When driving on hills:

. Use a low gear and keep a firmgrip on the steering wheel.

. Maintain a slow speed.

. When possible, drive straight upor down the hill.

. Slow down when approachingthe top of the hill.

. Use headlamps even during theday to make the vehicle morevisible.

{ Warning

Driving to the top of a hill at highspeed can cause a crash. Therecould be a drop-off, embankment,cliff, or even another vehicle. Youcould be seriously injured orkilled. As you near the top of ahill, slow down and stay alert.

. Never go downhill forward orbackward with either thetransmission or transfer case inN (Neutral). The brakes couldoverheat and you could losecontrol.

{ Warning

If the vehicle has the two-speedelectronic transfer case, shiftingthe transfer case to N (Neutral)can cause your vehicle to rolleven if the transmission is inP (Park). This is because theN (Neutral) position on the

(Continued)

Warning (Continued)

transfer case overrides thetransmission. You or someoneelse could be injured. If leavingthe vehicle, set the parking brakeand shift the transmission toP (Park). Shift the transfer case toany position but N (Neutral).

. When driving down a hill, keepthe vehicle headed straightdown. Use a low gear becausethe engine will work with thebrakes to slow the vehicle andhelp keep the vehicle undercontrol.

{ Warning

Heavy braking when going downa hill can cause your brakes tooverheat and fade. This couldcause loss of control and you orothers could be injured or killed.Apply the brakes lightly when

Warning (Continued)

descending a hill and use a lowgear to keep vehicle speed undercontrol.

If the vehicle stalls on a hill:

1. Apply the brakes to stop thevehicle, and then apply theparking brake.

2. Shift into P (Park) and thenrestart the engine.

. If driving uphill when thevehicle stalls, shift toR (Reverse), release theparking brake, and backstraight down.

. Never try to turn the vehiclearound. If the hill is steepenough to stall the vehicle,it is steep enough to causeit to roll over.

. If you cannot make it up thehill, back straight downthe hill.

. Never back down a hill inN (Neutral) using only thebrake. The vehicle can rollbackward quickly and youcould lose control.

. If driving downhill when thevehicle stalls, shift to alower gear, release theparking brake, and drivestraight down the hill.

3. If the vehicle cannot berestarted after stalling, set theparking brake, shift intoP (Park), and turn the vehicleoff. Block the wheels withchocks for added safety whenparking on a grade.

3.1. Leave the vehicle andseek help.

3.2. Stay clear of the path thevehicle would take if itrolled downhill.

. Avoid turns that take the vehicleacross the incline of the hill.A hill that can be driven straightup or down might be too steep todrive across. Driving across anincline puts more weight on the

downhill wheels, which couldcause a downhill slide or arollover.

. Surface conditions can be aproblem. Loose gravel, muddyspots, or even wet grass cancause the tires to slip sideways,downhill. If the vehicle slipssideways, it can hit somethingthat will trip it — a rock, a rut,etc. — and roll over.

. Hidden obstacles can make thesteepness of the incline moresevere. If a rock is driven acrosswith the uphill wheels, or if thedownhill wheels drop into a rutor depression, the vehicle can tilteven more.

. If an incline must be drivenacross, and the vehicle starts toslide, turn downhill. This shouldhelp straighten out the vehicleand prevent the side slipping.

200 Driving and Operating

{ Warning

Getting out of the vehicle on thedownhill side when stoppedacross an incline is dangerous.If the vehicle rolls over, you couldbe crushed or killed. Always getout on the uphill side of thevehicle and stay well clear of therollover path.

Parking on a Hill

Parking on a hill or steep grade isnot advised. See “Parking on Hills”in Driving Characteristics andTowing Tips 0 250 for more detailedinformation.

If parking on a hill or steep grade:

1. Press the brake pedal to stopthe vehicle, and then apply theparking brake.

2. Shift into P (Park), and thenturn the vehicle off.

3. Block the wheels with chocks.

Driving in Mud, Sand, Snow,or Ice

Use a low gear when driving inmud — the deeper the mud, thelower the gear. Keep the vehiclemoving to avoid getting stuck.

Traction changes when driving onsand. On loose sand, such as onbeaches or sand dunes, the tirestend to sink into the sand. Thisaffects steering, accelerating, andbraking. Drive at a reduced speedand avoid sharp turns or abruptmaneuvers.

Traction is reduced on hard packedsnow and ice and it is easy to losecontrol. Reduce vehicle speed whendriving on hard packed snowand ice.

{ Warning

Driving on frozen lakes, ponds,or rivers can be dangerous. Iceconditions vary greatly and thevehicle could fall through the ice;

(Continued)

Warning (Continued)

you and your passengers coulddrown. Drive your vehicle on safesurfaces only.

Driving in Water

{ Warning

Driving through rushing water canbe dangerous. Deep water cansweep your vehicle downstreamand you and your passengerscould drown. If it is only shallowwater, it can still wash away theground from under your tires.Traction could be lost, and thevehicle could roll over. Do notdrive through rushing water.

Driving and Operating 201

Caution

Do not drive through standingwater if it is deep enough to coverthe wheel hubs, axles, or exhaustpipe. Deep water can damage theaxle and other vehicle parts.

If the standing water is not too deep,drive through it slowly. At fasterspeeds, water can get into theengine and cause it to stall. Stallingcan occur if the exhaust pipe isunder water. Do not turn off theignition when driving through water.If the exhaust pipe is under water,the engine will not start. When goingthrough water, the brakes get wetand it may take longer to stop. See“Driving on Wet Roads” later in thissection.

After Off-Road Driving

Remove any brush or debris thathas collected on the underbody orchassis, or under the hood. Theseaccumulations can be a fire hazard.

After operation in mud or sand,have the brake linings cleaned andchecked. These substances cancause glazing and uneven braking.Check the body structure, driveline,steering, suspension, wheels, tires,and exhaust system for damage andcheck the fuel lines and coolingsystem for any leakage.

More frequent maintenance serviceis required. See MaintenanceSchedule 0 361.

Driving on Wet RoadsRain and wet roads can reducevehicle traction and affect yourability to stop and accelerate.Always drive slower in these typesof driving conditions and avoiddriving through large puddles anddeep-standing or flowing water.

{ Warning

Wet brakes can cause crashes.They might not work as well in aquick stop and could causepulling to one side. You couldlose control of the vehicle.

After driving through a largepuddle of water or a car/vehiclewash, lightly apply the brakepedal until the brakes worknormally.

Flowing or rushing water createsstrong forces. Driving throughflowing water could cause thevehicle to be carried away. If thishappens, you and other vehicleoccupants could drown. Do notignore police warnings and bevery cautious about trying to drivethrough flowing water.

Hydroplaning

Hydroplaning is dangerous. Watercan build up under the vehicle'stires so they actually ride on thewater. This can happen if the road is

202 Driving and Operating

wet enough and you are going fastenough. When the vehicle ishydroplaning, it has little or nocontact with the road.

There is no hard and fast rule abouthydroplaning. The best advice is toslow down when the road is wet.

Other Rainy Weather Tips

Besides slowing down, other wetweather driving tips include:

. Allow extra following distance.

. Pass with caution.

. Keep windshield wipingequipment in good shape.

. Keep the windshield washer fluidreservoir filled.

. Have good tires with propertread depth. See Tires 0 331.

. Turn off cruise control.

Hill and Mountain RoadsDriving on steep hills or throughmountains is different than drivingon flat or rolling terrain. Tips include:

. Keep the vehicle serviced and ingood shape.

. Check all fluid levels and brakes,tires, cooling system, andtransmission.

. Shift to a lower gear when goingdown steep or long hills.

{ Warning

Using the brakes to slow thevehicle on a long downhill slopecan cause brake overheating, canreduce brake performance, andcould result in a loss of braking.Shift the transmission to a lowergear to let the engine assist thebrakes on a steep downhill slope.

{ Warning

Coasting downhill in N (Neutral)or with the ignition off isdangerous. This can causeoverheating of the brakes andloss of steering assist. Alwayshave the engine running and thevehicle in gear.

. Drive at speeds that keep thevehicle in its own lane. Do notswing wide or cross thecenter line.

. Be alert on top of hills;something could be in your lane(e.g., stalled car, crash).

. Pay attention to special roadsigns (e.g., falling rocks area,winding roads, long grades,passing or no-passing zones)and take appropriate action.

Driving and Operating 203

Winter Driving

Driving on Snow or Ice

Snow or ice between the tires andthe road creates less traction orgrip, so drive carefully. Wet ice canoccur at about 0 °C (32 °F) whenfreezing rain begins to fall. Avoiddriving on wet ice or in freezing rainuntil roads can be treated.

For Slippery Road Driving:

. Accelerate gently. Acceleratingtoo quickly causes the wheels tospin and makes the surfaceunder the tires slick.

. The Antilock Brake System(ABS) improves vehicle stabilityduring hard stops, but thebrakes should be applied soonerthan when on dry pavement.See Antilock Brake System(ABS) 0 231.

. Allow greater following distanceand watch for slippery spots. Icypatches can occur on otherwiseclear roads in shaded areas.The surface of a curve or anoverpass can remain icy when

the surrounding roads are clear.Avoid sudden steeringmaneuvers and braking whileon ice.

. Turn off cruise control.

Blizzard Conditions

Stop the vehicle in a safe place andsignal for help. Stay with the vehicleunless there is help nearby.If possible, use RoadsideAssistance. See RoadsideAssistance Program 0 418. To gethelp and keep everyone in thevehicle safe:

. Turn on the hazard warningflashers.

. Tie a red cloth to an outsidemirror.

{ Warning

Snow can trap engine exhaustunder the vehicle. This maycause exhaust gases to getinside. Engine exhaust containscarbon monoxide (CO), which

(Continued)

Warning (Continued)

cannot be seen or smelled. It cancause unconsciousness and evendeath.

If the vehicle is stuck in snow:

. Clear snow from the base ofthe vehicle, especially anyblocking the exhaust pipe.

. Open a window about 5 cm(2 in) on the vehicle sidethat is away from the wind,to bring in fresh air.

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the climate controlsystem to circulate the airinside the vehicle and setthe fan speed to the highestsetting. See “ClimateControl Systems.”

For more information about CO,see Engine Exhaust 0 216.

204 Driving and Operating

To save fuel, run the engine forshort periods to warm the vehicleand then shut the engine off andpartially close the window. Movingabout to keep warm also helps.

If it takes time for help to arrive,when running the engine, push theaccelerator pedal slightly so theengine runs faster than the idlespeed. This keeps the batterycharged to restart the vehicle and tosignal for help with the headlamps.Do this as little as possible, tosave fuel.

If the Vehicle Is StuckSlowly and cautiously spin thewheels to free the vehicle whenstuck in sand, mud, ice, or snow.See “Rocking the Vehicle to Get ItOut” later in this section.

The Traction Control System canoften help to free a stuck vehicle.See Traction Control System (TCS)0 235. If TCS cannot free thevehicle, see “Rocking the Vehicle toGet it Out” following.

{ Warning

If the vehicle's tires spin at highspeed, they can explode, and youor others could be injured. Thevehicle can overheat, causing anengine compartment fire or otherdamage. Spin the wheels as littleas possible and avoid goingabove 56 km/h (35 mph).

For information about using tirechains on the vehicle, see TireChains 0 343.

Rocking the Vehicle to GetIt Out

Turn the steering wheel left andright to clear the area around thefront wheels. For four-wheel-drivevehicles, shift into Four-Wheel DriveHigh. Turn the TCS off. Shift backand forth between R (Reverse) anda forward gear, spinning the wheelsas little as possible. To preventtransmission wear, wait until thewheels stop spinning before shiftinggears. Slowly spinning the wheels in

the forward and reverse directionscauses a rocking motion that couldfree the vehicle. If that does not getthe vehicle out after a few tries, itmight need to be towed out. SeeTowing the Vehicle 0 347. Recoveryhooks can be used, if the vehiclehas them.

Recovery Hooks

{ Warning

Never pull on recovery hooksfrom the side. The hooks couldbreak and you and others couldbe injured. When using recoveryhooks, always pull the vehiclefrom the front.

Caution

Never use recovery hooks to towthe vehicle. The vehicle could bedamaged, and the repairs wouldnot be covered by the vehiclewarranty.

There are recovery hooks at thefront of the vehicle. Use them if thevehicle is stuck off-road and needsto be pulled some place to continuedriving.

Vehicle Load LimitsIt is very important to know howmuch weight the vehicle cancarry. This weight is called thevehicle capacity weight andincludes the weight of alloccupants, cargo, and allnonfactory-installed options.

{ Warning

Do not load the vehicle anyheavier than the GrossVehicle Weight Rating(GVWR), or either themaximum front or rear GrossAxle Weight Rating (GAWR).This can cause systems tobreak and change the way thevehicle handles. This couldcause loss of control and acrash. Overloading can alsoreduce stopping distance,damage the tires, and shortenthe life of the vehicle.

Driving and Operating 211

When the engine is cold, let it runfor a few minutes before driving.This lets oil pressure build up. Theengine will sound louder when itis cold.

For turbo protection, engine powerat speeds above idle may be limitedif the engine is cold. This protectioncan last up to a maximum of40 seconds at extreme cold coolantand ambient temperatures.

Cold Weather Starting

Use the recommended engine oilwhen the outside temperature dropsbelow freezing. See Engine Oil0 295. When the outsidetemperature drops below –18 °C (0 °F), use of the engine coolant heateris recommended.

If you experience longer crankingtimes, notice an unusual amount ofexhaust smoke, or are at higherelevations (over 2 135 m or 7,000 ft),you may use the engine coolantheater. See Engine Heater 0 212.

See Fuel for Diesel Engines 0 241for information on what fuel to use incold weather.

If the Diesel Engine Will NotStart

If the vehicle runs out of fuel, seeRunning Out of Fuel 0 246.

If the vehicle is not out of fuel, andthe engine will not start:

Turn the ignition key to ON/RUN.After the wait-to-start light goes off,turn the ignition key to START.

If the light does not go off, wait afew seconds, then try starting theengine again. See your dealer assoon as possible for a startingsystem check.

If the light comes on and then goesoff and you know the batteries arecharged, but the engine still will notstart, the vehicle needs service.

If the light does not come on whenthe engine is cold, the vehicleneeds service.

If the batteries do not have enoughcharge to start the engine, seeBattery - North America 0 312.

Check that the correct engine oilhas been used and changed atappropriate intervals. If the wrong oilis used, the engine may be harderto start.

Be sure to use the proper fuel forexisting weather conditions. SeeFuel for Diesel Engines 0 241.

If the engine starts, runs a shorttime, then stops, the vehicle needsservice.

{ Warning

Do not use gasoline or startingaids, such as ether, in the airintake. They could damage theengine, which may not becovered by the vehicle warranty.They could also cause a fire,which could cause seriouspersonal injury.

Engine Idle Variations

Under certain conditions the engineidle speed can vary or be elevated.Change in idle speed is normal anddoes not indicate a problem. Normal

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

212 Driving and Operating

conditions that can raise idle speedare low voltage, DPF regeneration,air conditioning compressor loads,and engine warmup. These speedscan range from approximately 600to 1000 rpm.

Elevated Idle

The engine has a cold temperaturehigh idle feature which elevates theengine idle speed from base idle to1050 to 1100 rpm when outsidetemperatures are below 0 °C (32 °F),and the engine coolant temperatureis below 65 °C (150 °F). This featureenhances heater performance byraising the engine coolanttemperature faster.

When the engine is started, it willslowly ramp up to the high idlespeed after a delay of a fewseconds up to approximatelytwo minutes. For this method towork properly there must be nothrottle or brake pedal faults.

The engine idle speed will return tonormal once the following conditionsare met:

. Engine coolant temperaturereaches 65 °C (150 °F)

. Air intake temperature reaches0 °C (32 °F)

The high idle speed will betemporarily interrupted and theengine speed will return to normal ifany of the following conditionsoccur:

. The brake pedal is applied.

. The accelerator pedal ispressed.

. The transmission is shifted outof P (Park) or N (Neutral).

. Vehicle speed is detected.

Once these inputs are removed, theengine idle speed will slowly rampback up to high idle after the normaldelay, if the conditions for enginecoolant temperature and air intaketemperature are still met.

Engine HeaterThe engine heater can provideeasier starting and better fueleconomy during engine warm-up incold weather conditions at or below−18 °C (0 °F). Vehicles with anengine heater should be plugged inat least four hours before starting.An internal thermostat in theplug-end of the cord may exist,which will prevent engine heateroperation at temperatures above−18 °C (0 °F).

{ Warning

Do not plug in the engine blockheater while the vehicle is parkedin a garage or under a carport.Property damage or personalinjury may result. Always park thevehicle in a clear open area awayfrom buildings or structures.

can move the shift lever away fromP (Park) without first pulling it towardyou. If you can, it means that theshift lever was not fully locked intoP (Park).

Torque Lock

If you are parking on a hill and youdo not shift the transmission intoP (Park) properly, the weight of thevehicle may put too much force onthe parking pawl in thetransmission. You may find it difficultto pull the shift lever out of P (Park).This is called torque lock. Toprevent torque lock, set the parkingbrake and then shift into P (Park)properly before you leave thedriver seat.

When you are ready to drive, movethe shift lever out of P (Park) beforeyou release the parking brake.

If torque lock does occur, you mayneed to have another vehicle pushyours a little uphill to take some ofthe pressure from the parking pawlin the transmission. You will then beable to pull the shift lever out ofP (Park).

Shifting out of ParkThis vehicle is equipped with anelectronic shift lock release system.The shift lock release system isdesigned to prevent movement ofthe shift lever out of P (Park), unlessthe ignition is on and the brakepedal is applied.

The shift lock release is alwaysfunctional except in the case of anuncharged or low voltage (less than9 volt) battery.

If the vehicle has an unchargedbattery or a battery with low voltage,try charging or jump starting thebattery. See Jump Starting - NorthAmerica 0 343.

To shift out of P (Park):

1. Apply the brake pedal.

2. Move the shift lever to thedesired position.

If you still are unable to shift out ofP (Park):

1. Ease the pressure on the shiftlever.

2. While holding down the brakepedal, push the shift lever allthe way into P (Park).

3. Move the shift lever to thedesired position.

If you are still having a problemshifting, then have the vehicleserviced soon.

If parking on a hill and pulling atrailer, see Driving Characteristicsand Towing Tips 0 250.

Diesel ParticulateFilterThe vehicle has a Diesel ParticulateFilter (DPF) as part of the exhaustsystem to reduce vehicle emissions.The DPF requires a unique exhausttailpipe with an exhaust cooler. Theexhaust cooler mixes air with theexhaust to lower the temperaturebefore it leaves the tailpipe.

The DPF, the tailpipe, or otherexhaust system components mustnot be altered. Inspect regularly andclean any mud or dirt from theexhaust cooler, especially where theexhaust cooler connects to thetailpipe and the openings wherefresh air enters the cooler.

The DPF will clean itself as part ofnormal operation. Several factorsincluding fuel consumed, hours ofengine operation, and miles drivenare monitored by the Engine ControlModule (ECM). The self-cleaningoccurs approximately once per tankof fuel.

Caution

Damage can occur to the DPFcomponents if the required UltraLow Sulfur Diesel (15 ppm sulfurmaximum) fuel and either CJ-4 orCK-4 engine oil are not used.This damage would not becovered by the vehicle warranty.

Under certain driving conditions,such as stop-and-go traffic, the filtercannot clean itself. A messagecomes on when the DPF is dirty andneeds to perform a self cleaning.

For the filter to clean itself, thevehicle must be driven above50 km/h (30 mph) until the messagegoes off. This will take about30 minutes.

See Accessories and Modifications0 290 for important information ifyou are considering addingaccessories or modifying thevehicle.

Manual Regeneration of DieselParticulate Filter

If equipped, this feature allows formanual cleaning/regeneration of theDPF when it is unable to cleanitself. It may be necessary toperform a manual regeneration ifdriving conditions — such asextended slow speed, stop-and-gotraffic, extended idles, short drivecycles, or stationary PTOoperation — prevent DPFself-cleaning.

Driving and Operating 219

Manual regeneration can only beused when the DPF has become atleast 90% full. At 100% full, it willattempt to automatically self-clean ifproper driving conditions are met.The DPF will clean itself if thevehicle can be driven above50 km/h (30 mph) for about30 minutes.

A Driver Information Center (DIC)message displays when manualregeneration is possible.

Scroll through the DIC pages to findthe Exhaust Filter menu. Dependingon whether the vehicle has a baseor uplevel cluster, it may be underthe Options menu.

If the vehicle cannot be stoppedwhen the DIC message firstindicates cleaning is available,automatic self-cleaning may havebegun. If conditions cannot be metfor self-cleaning to complete, andmanual regeneration is selected, itmay take up to four minutes for thesystem to switch to manualregeneration. When the switchoccurs, a DIC message prompts tostart the cleaning process.

{ Warning

Do not leave the vehicle duringthe regeneration.

Make sure that there are noflammables near the muffler, DPFand exhaust pipe which mayresult in a fire.

Remember that the temperatureof exhaust gases is high enoughto burn you. You and others couldbe seriously injured.

Before starting the manualregeneration, make sure all of thefollowing safety conditions are met:

. The vehicle is parked on levelground, away from anyflammable materials.

. The vehicle is parked outdoors,away from any walls orbuildings.

. The vehicle is at least 3 m (10 ft)from any obstructions ormaterials that may combustor melt.

. The shift lever is in P (Park).

. The fuel tank is at leastone-eighth full.

. All fluids are at the proper level.

. No diagnostic trouble codeshave been set, and themalfunction indicator lamp isnot on.

. The engine coolant temperatureis above 71 °C (160 °F).

After making sure all of the safetyconditions have been met, press thetrip odometer reset stem or@ onthe steering wheel control for atleast one second to select Start onthe DIC.

Follow the instructions in the DICmessages. Choose ACCEPT toacknowledge that all of these safetyconditions have been met and toactivate regeneration.

If the DIC returns to the previousscreen, then one or more of thenecessary operating conditions hasnot been met.

Continue to follow the instructions inthe DIC messages. Press and holdthe exhaust brake switch on thecenter stack below the climatecontrols for more thanthree seconds, and then release it,to begin the regeneration process.

If the EXHAUST BRAKE ONmessage displays, then the switchwas released too soon. Press itagain to turn off the exhaust brake,then try again when the DICmessage prompts.

When manual regeneration begins,the engine speed increases, theengine cooling fan sound increases,and a DIC message indicates thatcleaning is in progress.

A DIC message will display whencleaning has completed. Themessage will remain as long ascleaning is not necessary. Cleaningcould take up to 30 minutes. Uponcompletion, the engine will return tonormal idle, but exhaustcomponents will remain hot forseveral minutes. Do not move thevehicle until the exhaust has hadtime to cool. Manual regenerationcan be canceled at any time bypressing the brake pedal or turningthe engine off. Unusual noises maybe heard if regeneration isinterrupted.

Diesel Exhaust Fluid

{ Warning

Avoid getting Diesel ExhaustFluid (DEF) on your skin or inyour eyes as it could causeirritation. For more safety,handling, and storage information,see the Diesel Exhaust Fluidcontainer label.

Caution

Do not mix fuel with DEF, and donot put DEF in the fuel tank. Thiscould lead to costly repairs thatmight not be covered by thevehicle warranty.

Diesel Exhaust Fluid (DEF) is usedwith diesel engines to reduce theamount of regulated emissionsproduced. Products such as AdBlueare types of DEF, and are approvedfor use in the vehicle as long asthey have an API certification label

or meet ISO 22241.The fluid level inthe DEF tank must be maintainedfor the vehicle to run properly. DEFfreezes when exposed totemperatures below −11 °C (12 ° F).For DEF tank capacity seeCapacities and Specifications 0 408.

It is normal to hear the DEF systempurge fluid back into the tank afterthe vehicle is shut off.

Locating Diesel Exhaust Fluid

DEF can be purchased at yourdealer. It can also be purchased atauthorized vehicle and truckdealerships. Additionally, somediesel truck fueling stations orretailers may have DEF forpurchase. For vehicles with anactive OnStar or connected serviceplan, OnStar can help to locate aDEF retailer. See RecommendedFluids and Lubricants 0 398.

Filling the DEF Tank

Caution

Use only DEF that is GMapproved, or fluid containing theAPI certified or ISO 22241 label.The use of other fluids coulddamage the system, requiringcostly repairs that will not becovered by the vehicle warranty.

It is recommended to fill the DEFtank on level ground and when thevehicle is not running.

When adding fluid, it isrecommended to fill the DEF tank.For DEF tank capacity seeCapacities and Specifications 0 408.

222 Driving and Operating

In certain cold conditions, it ispossible to find some frozen DEF inthe DEF fill pipe opening. If thiscondition prevents the filling of aDEF tank, place the vehicle in awarm garage overnight.

Exhaust Fluid Low

As the DEF level drops, the DriverInformation Center (DIC) will displaywarnings. DEF level status isavailable on the DIC under thevehicle Information button. See“Exhaust Fluid Level” in DriverInformation Center (DIC) (BaseLevel) 0 119 or Driver InformationCenter (DIC) (Uplevel) 0 120.

To avoid vehicle speed limitations,fill the DEF tank at the firstopportunity after a low fluid levelwarning. If DEF is added before theEXHAUST FLUID EMPTY REFILLNOW message appears, it may takeseveral km/mi for the DIC messageto update.

If vehicle speed has been limitedand DEF has been added, it maytake up to 30 seconds after enginestart with the vehicle stopped for the

refill message to clear. If the vehicleis driven before the DIC messageclears, vehicle speed will still belimited. If the DIC message clearswhile driving, the speed limitationwill be removed gradually.

If DEF is added under freezingconditions, additional time may berequired to remove speedlimitations, and it may require lessfluid to fill the DEF tank.

Based on driving conditions andvehicle configuration, the amountneeded to fill the tank will vary. Asthe fluid level nears empty, thesemessages will appear every timethe vehicle is started.

If these warnings are ignored andthe DEF tank becomes empty, theDIC will indicate the action neededand distance until vehicle speed islimited.

The speed limitation will occur in aseries of steps, with the final speedlimitation being 8 km/h (5 mph)accompanied by a flashing warninglight and chimes. It is recommendedto fully fill the DEF tank, but at least

7.6 L (2 gal) of DEF must be addedto release the vehicle from thespeed limitation. See Capacitiesand Specifications 0 408, DieselExhaust Fluid (DEF) Warning Light0 117, and Recommended Fluidsand Lubricants 0 398.

Exhaust Fluid Quality Poor

Use only DEF that is GM approved,or fluid containing the API certifiedor ISO 22241 label.

DEF has an expiration date. If thesystem detects poor quality,or contaminated or diluted DEF, theDIC will display EXHAUST FLUIDQUALITY POOR - SEE OWNERSMANUAL NOW and will show thedistance until vehicle speed islimited.

224 Driving and Operating

When parked on a hill, especiallywhen the vehicle has a heavy load,you might notice an increase in theeffort to shift out of P (Park). See“Torque Lock” under Shifting IntoPark 0 214.

{ Warning

It is dangerous to get out of thevehicle if the shift lever is not fullyin P (Park) with the parking brakefirmly set. The vehicle can roll.

Do not leave the vehicle when theengine is running. If you have leftthe engine running, the vehiclecan move suddenly. You or otherscould be injured. To be sure thevehicle will not move, even whenyou are on fairly level ground,always set the parking brake andmove the shift lever to P (Park).See Shifting Into Park 0 214 andDriving Characteristics andTowing Tips 0 250.

R : Use this gear to back up.

Caution

Shifting to R (Reverse) while thevehicle is moving forward coulddamage the transmission. Therepairs would not be covered bythe vehicle warranty. Shift toR (Reverse) only after the vehicleis stopped.

To rock the vehicle back and forth toget out of snow, ice, or sand withoutdamaging the transmission, see Ifthe Vehicle Is Stuck 0 204.

N : In this position, the engine doesnot connect with the wheels. Torestart the engine when the vehicleis already moving, useN (Neutral) only.

Also, use N (Neutral) when thevehicle is being towed.

{ Warning

Shifting into a drive gear while theengine is running at high speed isdangerous. Unless your foot isfirmly on the brake pedal, thevehicle could move very rapidly.You could lose control and hitpeople or objects. Do not shiftinto a drive gear while the engineis running at high speed.

Caution

Shifting out of P (Park) orN (Neutral) with the enginerunning at high speed maydamage the transmission. Therepairs would not be covered bythe vehicle warranty. Be sure theengine is not running at highspeed when shifting the vehicle.

Driving and Operating 225

Caution

A transmission hot message maydisplay if the automatictransmission fluid is too hot.Driving under this condition candamage the vehicle. Stop and idlethe engine to cool the automatictransmission fluid. This messageclears when the transmission fluidhas cooled sufficiently.

D : This position is for normaldriving. It provides the best fueleconomy. If more power is neededfor passing, press the acceleratorpedal down.

. Going less than about 55 km/h(35 mph), push the acceleratorpedal about halfway down.

. Going about 55 km/h (35 mph) ormore, push the accelerator allthe way down.

By doing this, the vehicle shiftsdown to the next gear and hasmore power.

Use D (Drive) and Tow/Haul Modewhen towing a trailer, carrying aheavy load, driving on steep hills,or driving off-road. Shift thetransmission to a lower gearselection if the transmission shiftstoo often.

Downshifting the transmission inslippery road conditions could resultin skidding. See “Skidding” underLoss of Control 0 196.

The vehicle has a shift stabilizationfeature that adjusts the transmissionshifting to the current drivingconditions in order to reduce rapidupshifts and downshifts. This shiftstabilization feature is designed todetermine, before making anupshift, if the engine is able tomaintain vehicle speed by analyzingthings such as vehicle speed,throttle position, and vehicle load.If the shift stabilization featuredetermines that a current vehiclespeed cannot be maintained, thetransmission does not upshift andinstead holds the current gear.

In some cases, this could appear tobe a delayed shift, however thetransmission is operating normally.

The transmission uses adaptiveshift controls. The adaptive shiftcontrol process continuallycompares key shift parameters topre-programmed ideal shifts storedin the transmission’s computer. Thetransmission constantly makesadjustments to improve vehicleperformance according to how thevehicle is being used, such as witha heavy load or when thetemperature changes. During thisadaptive shift control process,shifting might feel different as thetransmission determines the bestsettings.

When temperatures are very cold,the transmission's gear shiftingcould be delayed providing morestable shifts until the engine warmsup. Shifts could be more noticeablewith a cold transmission. Thisdifference in shifting is normal.

Kickdown Mode

If equipped, the accelerator pedalprovides an additional downshiftafter pressing through the kickdownfeature.

It requires extra pedal pressure nearthe end of its travel to engage.

Manual Mode

Range Selection Mode

If equipped, Range Selection Modehelps control the vehicle'stransmission and vehicle speedwhile driving downhill or towing atrailer by letting you select a desiredrange of gears.

To use this feature:

1. Move the shift lever toL (Manual Mode).

2. Press the plus/minus buttonson the shift lever to select thedesired range of gears forcurrent driving conditions.

When the shift lever is moved fromD (Drive) to L (Manual Mode), anumber displays next to the L,indicating the current transmissionrange.

This number is the highest gear thatthe transmission will command whileoperating in L (Manual Mode). Allgears below that number areavailable. As driving conditionschange, the transmission canautomatically shift to lower gears.For example, when L5 is selected,1 (First) through 5 (Fifth) gears areautomatically shifted by thetransmission, but 6 (Sixth) cannot beused until the plus/minus button onthe shift lever is used to change tothe range.

Grade Braking is not available whenRange Selection Mode is active.See Tow/Haul Mode 0 227.

While using Range Selection Mode,cruise control and the Tow/HaulMode can be used.

If the vehicle has an exhaust brake,it can also be used, but will notautomatically downshift thetransmission. See Exhaust Brake0 234

Drive Systems

Four-Wheel DriveIf equipped with four-wheel drive,the engine's driving power can besent to all four wheels for extratraction.

Caution

Do not drive on clean, dry

pavement in 4 m and 4 n (ifequipped) for an extended periodof time. These conditions maycause premature wear on thevehicle’s powertrain.

Driving on clean, dry pavement in4 m or 4 n may:

. Cause a vibration to be felt inthe steering system.

. Cause tires to wear faster.

. Make the transfer case harder toshift, and cause it to run noisier.

Caution

Extended high-speed operation in

4 n may damage or shorten thelife of the drivetrain.

Engagement noise and bump whenshifting between 4 n and 4 m, withthe engine running, is normal.

Manual Locking Hubs

unsafe to unlock them. Turn thelocking hubs to FREE when it issafe to do so.

When four-wheel drive is no longerneeded turn the locking hubs toFREE. If the hubs are locked intwo-wheel drive you may experiencedriveline vibration.

Electronic Transfer Case

Use the transfer case knob, next tothe steering wheel, to shift into andout of four-wheel drive for extratraction.

All of the lights will flash on then offmomentarily when the ignition isturned on. The light that remains onwill indicate the state of thetransfer case.

If the indicator mark on the switchdoes not match up with the lightthen that likely means the switchwas moved when the ignitionwas off.

The indicator mark on the switchmust line up with the indicator lightbefore a shift can be commanded.To command a shift rotate thetransfer case switch to the newdesired position. The light will flashmeaning that the shift is in progress.When the shift is completed the newposition will be illuminated. If thetransfer case cannot complete ashift command, it will go back to itslast chosen setting.

Delayed shifts from 4 m to 2 m may beexperienced due to uneven tirewear, low tire pressure, high vehicleloading, or cold temperatures.

Brakes

Antilock BrakeSystem (ABS)ABS is designed to enhance overallvehicle safety when a vehicle isdriven within its safe operatinglimits. ABS cannot compensate for avehicle which is being drivenbeyond the physical limits of control.Drivers operating an ABS equippedvehicle should employ safe drivingpractices and assume no additionaldriving risks.

{ Warning

To prevent property damage,personal injury, and/or death,if the ABS warning indicatorcomes on, have the ABS systemrepaired immediately as stoppingdistances may increase undercertain braking conditions. Takeevery precaution to prevent wheellockup, which could result in lossof vehicle control.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

232 Driving and Operating

The Antilock Brake System is amandated feature included in thehydraulic brake system.It electronically monitors vehiclewheel speed at all times, and onlyengages when wheel lock isimminent. The standard hydraulicbrake system controls normalbraking when the ABS is notengaged.

ABS Operation

ABS requires no changes in drivingpractices. For the best stoppingperformance with or without ABS,modulate — do not pump — thebrake pedal until the vehicle slowsto the desired speed or stops. Beaware that ABS on a towing vehicledoes not control brakes on towedvehicles. Towed vehicles may ormay not have ABS. ABS will preventlockup of controlled wheels if youover-brake for existing roadconditions. Optimum vehicle controlfor existing road conditions will beprovided as a result of the ABSpreventing wheel lockup at speedsabove approximately 6 km/h(4 mph). The ABS cannot provide

any better braking and steeringcapability than the available roadtraction will permit. If the road isslippery, it will take longer to stopthan on a dry road. Steeringmaneuverability will be similarlylimited. Vehicle speed must bereduced to compensate for theextended time and distance requiredto stop or slow the vehicle onslippery roads.

The wheel hubs carry exciter ringsused by the axle mounted sensorsto transmit wheel speed informationto the ABS electronic control unitlocated on the chassis frame. Thecontrol unit monitors and comparesall wheel speed inputs to determineif any wheel(s) are about to lock.If wheel lockup is about to occur,the control unit commands theappropriate modulator valve toadjust pressure delivery to preventwheel lockup.

If over-braking causes wheel lockupon the rear drive axles whileretarding devices are in operation,

the ABS will interrupt and disablethe retarder until the lockup situationhas stopped.

The ABS is equipped with a warningindicator in the instrument cluster.Each time the ignition is turned on,the ABS warning indicator willilluminate for several seconds andthen turn off. If an ABS fault isdetected, the warning indicator willstay on steady and ABS fault codeswill be electronically stored in theABS controller.

Antilock Driving Tips. Use controlled, even pressure to

stop the vehicle, being carefulnot to skid. Most effectivestopping will be achieved in thissituation.

. If the vehicle begins to skid,maintain even pressure on thebrake pedal. The ABS controllerwill rapidly cycle the brakes onthe skidding wheel(s), whilemaintaining even pressure onthe non-skidding wheels.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Driving and Operating 233. While maintaining even pressure

on the brake pedal, steer aroundany hazardous objects inyour path.

. Attempt to steer clear of traffic,pedestrians, or other obstacleswhile you are in an emergencybraking situation. ABS will allowyou to steer the vehicle duringbraking while it comes to a fullstop. ABS is not an excuse totake unnecessary risks. Alwaysdrive carefully and stay a safedistance away from the vehiclein front of you.

. Do not pump the brake pedalduring a skid unless the ABSsystem is not functioning.

ABS Self-Check

If an antilock fault develops,standard brake system operation ismaintained. The brake system is stilloperational, but the antilock systemdoes not operate to prevent wheellockup if you over apply the brakesfor existing conditions.

If the ABS indicator staysilluminated, have the systemserviced immediately.

A warning light on the instrumentcluster indicates the status of theABS. If the system is workingnormally when the ignition is turnedon, the ABS indicator comes on forseveral seconds before going out.

Parking Brake

Set the parking brake by holding theregular brake pedal down, thenpushing down the parking brakepedal.

If the ignition is on, the brakesystem warning light will come on.See Brake System Warning Light0 115.

Caution

Driving with the parking brake oncan overheat the brake systemand cause premature wear ordamage to brake system parts.Make sure that the parking brakeis fully released and the brakewarning light is off before driving.

To release the parking brake, holdthe regular brake pedal down, thenpush down momentarily on theparking brake pedal until you feelthe pedal release. Slowly pull yourfoot up off the parking brake pedal.If the parking brake is not releasedwhen you begin to drive, a DICmessage will appear and a chimewill sound warning you that theparking brake is still on.

234 Driving and Operating

Exhaust BrakeThe exhaust brake can be used toenhance the vehicle brake systemand reduce brake lining wear.

Downshifts may be automaticallyselected to increase engine speed,which increases the effectiveness ofthe exhaust brake. The number ofdownshifts selected is determinedby the length of time the brakes areapplied and the rate the vehicle isslowing. The system delivers thecorrect amount of braking to assistin vehicle control. The heavier thevehicle load, the more active theengine exhaust brake will be. Use ofthe exhaust brake will help maintainvehicle speed when used withcruise control. See Cruise Control0 237.

Automatic downshifts will not occurif the vehicle is in Range SelectionMode. See Manual Mode 0 226.

The exhaust brake only activateswhen the transmission torqueconverter is locked. This can varybased on vehicle speed, gear,and load.

To activate the system, press theexhaust brake switch. A light in theswitch will come on when theexhaust brake is activated. Theswitch must be pressed at eachvehicle start for the system to beactive.

The Driver Information Center (DIC)displays the message EXHAUSTBRAKE ON for approximatelythree seconds, then clears.

To turn the brake off, press theexhaust brake switch a second time.The DIC displays the messageEXHAUST BRAKE OFF forapproximately three seconds, thenclears.

The exhaust brake will be moreactive when in Tow/Haul Mode.

A light comes on in the instrumentcluster when the exhaust brake andTow/Haul are activated. The switchmust be pressed at each vehiclestart for the system to be active.

Ride Control Systems

Traction ControlSystem (TCS)

System Operation

The vehicle has a Traction ControlSystem (TCS).. This system helpslimit wheel spin and assist the driverin maintaining control, especially onslippery road conditions.

TCS activates if it senses any of thedrive wheels are spinning orbeginning to lose traction. When thishappens, TCS applies the brakes tothe spinning wheel(s) and reducesengine power to limit wheel spin.

If cruise control is being used andtraction control begins to limit wheelspin, cruise control will disengage.Cruise control may be turned backon when road conditions allow.

TCS comes on automatically whenthe vehicle is started and begins tomove. The system may be heard orfelt while operating or while

performing diagnostic checks. Thisis normal and does not mean thereis a problem with the vehicle.

It is recommended to leave TCS onfor normal driving conditions, but itmay be necessary to turn TCS off ifthe vehicle gets stuck in sand, mud,ice, or snow. See If the Vehicle IsStuck 0 204 and “Turning theSystems Off and On” later in thissection.

The indicator light for TCS is in theinstrument cluster. This light will:

. Flash when TCS is limitingwheel spin

. Turn on and stay on when TCSis not working

If TCS fails to turn on or to activate,a message displays in the DriverInformation Center (DIC), and dcomes on and stays on to indicate

that the system is inactive and is notassisting the driver in maintainingcontrol. The vehicle is safe to drive,but driving should be adjustedaccordingly

If d comes on and stays on:

1. Stop the vehicle.

2. Turn the engine off and wait15 seconds.

3. Start the engine.

Drive the vehicle. If d comes onand stays on, the vehicle may needmore time to diagnose the problem.If the condition persists, see yourdealer.

Fuel AdditivesTOP TIER Detergent Diesel ishighly recommended for use withyour vehicle. If your area does nothave TOP TIER Detergent Diesel,GM recommends the use ofACDelco Diesel Fuel Conditioner.This will help maintain optimalengine performance. GM does notrecommend other aftermarket dieseladditives.

If low-quality diesel is used forrefueling, GM recommends addingACDelco Fuel System TreatmentPlus-Diesel to help clean enginedeposits. This is available only atyour GM dealer.

Fuel for Diesel EnginesThe selection of a high-quality fuelis important for maintaining optimumvehicle performance. Diesel fuelshould meet or exceed the minimumrequirements in the most currentversions of the local fuel standards

Do not use fuel with more than 15ppm sulfur.

Do not use a diesel blend containingmore than 20% biodiesel by volume.

Caution

Use of fuel that does not complywith the required technicalstandards can lead to enginepower loss, increased wear,or engine damage and may voidyour warranty.

Some improper fuels are:

. Diesel fuel with the additionof gasoline.

. Diesel fuel mixed withengine oil or automatictransmission fluid.

. Triglyceride fuels, such asraw vegetable oil or animalfat, in any form, includingwith blends of diesel orbiodiesel.

. Marine diesel fuel andfuel oils.

(Continued)

Caution (Continued)

. Diesel-water emulsions,such as Aquazole.

. Aftermarket diesel fueladditives, which containalcohols, organo-metallicadditives, or wateremulsifiers.

Caution

If the vehicle is accidentallyrefueled with gasoline, do notcontinue driving the vehicle.Driving the vehicle will damagethe fuel system. Have the vehicletowed to a qualified technician tohave the gasoline removed fromthe tank and fuel system. Refuelwith Ultra Low Sulfur Diesel fuel.It is also recommended to havethe fuel system flushed with UltraLow Sulfur Diesel, to ensure allgasoline is removed.

242 Driving and Operating

Some conditions, such as dirty fuel,may decrease fuel filter life and aCHANGE FUEL FILTER messagemay come on in the DriverInformation Center (DIC).

Climate Grade Diesel Fuels

At temperatures below 0 °C (32 °F),avoid using biodiesel blends above5% by volume. Using such a fuelmay cause fuel filter plugging,system gelling, and freezing, whichmay adversely impact vehiclestarting.

Severe winter grade diesel fuel,such as 1-D diesel fuel or Arcticgrade diesel fuel, can be used inextreme cold temperatures (below−18 °C or 0 °F); however, doing sowill reduce power and fuel economy.Avoid using severe winter grade fuelin warm or hot climates. It can resultin stalling, poor starting, anddamage to the fuel injection system.

Fuels improperly blended for coldtemperature operation may result inrestricted fuel filters. The vehicle isequipped with a fuel heating systemto prevent gelling or waxing of

conventional diesel fuel andbiodiesel blends, but may notprevent all cases.

In case of severe winter conditions,the fuel filter may become cloggedby wax naturally present in the fuel.To unclog it, move the vehicle to awarm garage area and allow thefilter to warm up. The fuel filter mayneed to be replaced. See Fuel FilterReplacement 0 247.

BiodieselBiodiesel is a renewable fuelproduced from vegetable oils oranimal fats that have beenchemically modified to make itcompatible with diesel fuel.

Caution

Do not use home-made biodieselor home test kits because thequality cannot be verified byapproved scientific methods. Donot use raw vegetable oil or otherunmodified bio-oils, fats,

(Continued)

Caution (Continued)

or blends of vegetable oil withdiesel. They could damage thefuel system and engine, anddamages would not be coveredby the vehicle warranty.

Biodiesel Blends

Fuels with a biodiesel content up to20% by volume may be used (e.g.,named B20). Only use biodieselblends up to 20% by volume thatcomply with your country’s orregion’s fuel standards.

Caution

Do not use blends containingmore than 20% biodiesel. Anyengine, fuel system, or exhaustafter-treatment system damagewould not be covered by thevehicle warranty.

Driving and Operating 243

As a renewable fuel, biodieselprovides some environmentalbenefits. However, biodiesel hasunique properties and needs to behandled differently than diesel fuel.Its use presents additional risks andmay not be appropriate in allsituations. Certain vehicle operatingmodes increase these risks andshould be avoided.

Biodiesel fuel quality degrades withtime and exposure to hightemperature quicker than Ultra LowSulfur Diesel fuel. More frequentrefueling provides the bestopportunity to have a supply of freshfuel. Storage at hot ambienttemperatures will acceleratebiodiesel degradation.

If the vehicle is not driven often anduses little fuel, or if it is stored forextended periods of time, avoid theuse of biodiesel blended fuelsabove 5% by volume. When thevehicle is stored for longer than onemonth, it should be run out ofbiodiesel to below one-quarter tank,

refueled with biodiesel-free fuel, anddriven several kilometers (miles)before storage.

Cold Weather OperationIn cold weather, the fuel filter maybecome clogged by wax naturallypresent in the fuel. To unclog it,move the vehicle to a warm garagearea and allow the filter to warm up.The fuel filter may need to bereplaced. See Fuel FilterReplacement 0 247.

At temperatures below 0 °C (32 °F),it is recommended to avoid usingbiodiesel blends above 5% blend.This blend may cause fuel filterplugging, system gelling, andfreezing that may affect vehiclestarting. You may need to turn theignition on and off a few timesbefore the vehicle will start. Also,idle the vehicle for a couple ofminutes before accelerating.

It is recommended to use Ultra LowSulfur No. 1-D diesel fuel or a blendof No. 1-D and No. 2-D diesel fuel toenhance vehicle operation in cold

weather at temperatures below 0 °C(32 °F). Use of No. 1-D diesel fuelmay lower the fuel economy. Foradditional information for better coldweather operation, see EngineHeater 0 212.

Water in FuelImproper fuel tank inspection orcleaning, or contaminated fuel fromsuppliers, can cause water to bepumped into the fuel tank along withthe diesel fuel. If a WATER IN FUELSERVICE REQUIRED messagedisplays, the water must be drainedimmediately.

{ Warning

Diesel fuel containing water is stillcombustible. You or others couldbe burned. If the fuel needs to bedrained, keep sparks, flames, andsmoking materials away from themixture.

5. Start the engine and let it runfor a few minutes. During thedraining process, air may haveentered the fuel system. If theengine stalls, the fuel systemmay need to be primed. See“Fuel Priming” following.

Fuel Priming

For the fuel system to work properly,the fuel lines must be full of fuel.If air gets in, the fuel lines need tobe primed before operating thevehicle.

If air is present, the following mayhave happened:

. The vehicle ran out of fuel.

. The fuel filter was removed.

. The fuel lines were removed ordisconnected.

. The fuel filter water drain valvewas opened while the enginewas running.

Priming the Fuel System

There is an electric priming pumpthat will bring fuel to the engine andeliminate air in the fuel lines. Toprime the engine:

1. Correct any condition thatcaused the loss of prime.

2. Turn the ignition on for30 seconds. Do not start theengine. The fuel pump will startpriming.

3. Turn the ignition off, then backto START, and crank theengine for 15 seconds.

4. If the engine does not start,repeat Steps 2 and 3 until theengine starts.

If the engine does not startafter repeating Steps 2 and 3three times, turn the ignition offfor 60 seconds.

5. Repeat the above steps untilthe engine starts.

6. If the engine starts, but doesnot run smoothly, increase theengine speed slightly.

7. If the engine starts and runsbut stalls again, turn theignition off for 60 seconds.

8. When the engine starts, let itidle for a few minutes andcheck the filter for any leaks.

Running Out of Fuel

{ Warning

Diesel fuel is combustible. It couldstart a fire if it gets on hot engineparts. You could be burned. Catchany fuel from the air bleed valve,and wipe up any spilled fuel witha cloth.

If the engine has stalled due torunning out of fuel, try the followingsteps to restart it:

1. If parked on a level surface,add at least 7.6 L (2 gal) offuel. Up to 18.9 L (5 gal) maybe needed if parked on aslope.

as expected. You and otherscould be seriously injured. Thevehicle may also be damaged,and the repairs would not becovered by the vehicle warranty.Pull a trailer only if all the steps inthis section have been followed.Ask your dealer for advice andinformation about towing a trailerwith the vehicle.

Driving with a Trailer

Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.

The following information has manytime-tested, important trailering tipsand safety rules. Many of these are

important for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.

When towing a trailer:

. Become familiar with and followall state and local laws thatapply to trailer towing. Theserequirements vary from state tostate.

. State laws may require the useof extended side view mirrors.Even if not required, you shouldinstall extended side viewmirrors if your visibility is limitedor restricted while towing.

. Do not tow a trailer during thefirst 800 km (500 mi) of vehicleuse to prevent damage to theengine, axle, or other parts.

. It is recommended to performthe first oil change before heavytowing.

. During the first 800 km (500 mi)of trailer towing, do not driveover 80 km/h (50 mph) and donot make starts at full throttle.

. Vehicles can tow in D (Drive).Tow/Haul Mode is recommendedfor heavier trailers. See Tow/Haul Mode 0 227. If thetransmission downshifts toooften, a lower gear may beselected using Manual Mode.See Manual Mode 0 226.

{ Warning

To prevent serious injury or deathfrom carbon monoxide (CO),when towing a trailer:

. Do not drive with theliftgate, trunk/hatch,or rear-most window open.

. Fully open the air outlets onor under the instrumentpanel.

. Adjust the climate controlsystem to a setting thatbrings in only outside air.See “Climate ControlSystems” in the Index.

252 Driving and Operating

Warning (Continued)

For more information aboutcarbon monoxide, see EngineExhaust 0 216.

Towing a trailer requires experience.The combination of the vehicle andtrailer is longer and not asresponsive as the vehicle itself. Getused to the handling and braking ofthe combination by driving on alevel road surface before driving onpublic roads.

The trailer structure, the tires, andthe brakes must be all be rated tocarry the intended cargo.Inadequate trailer equipment cancause the combination to operate inan unexpected or unsafe manner.Before driving, inspect all trailerhitch parts and attachments, safetychains, electrical connectors, lamps,tires, and mirrors. See TowingEquipment 0 257. If the trailer haselectric brakes, start thecombination moving and thenmanually apply the trailer brake

controller to check the trailer brakeswork. During the trip, occasionallycheck that the cargo and trailer aresecure and that the lamps and anytrailer brakes are working.

Following Distance

Stay at least twice as far behind thevehicle ahead as you would whendriving without a trailer. This canhelp to avoid heavy braking andsudden turns.

Passing

More passing distance is neededwhen towing a trailer. Thecombination of the vehicle andtrailer will not accelerate as quicklyand is much longer than the vehiclealone. It is necessary to go muchfarther beyond the passed vehiclebefore returning to the lane. Passon level roadways. Avoid passingon hills if possible.

Backing Up

Hold the bottom of the steeringwheel with one hand. To move thetrailer to the left, move that hand tothe left. To move the trailer to the

right, move that hand to the right.Always back up slowly and,if possible, have someoneguide you.

Making Turns

Caution

Turn more slowly and make widerarcs when towing a trailer toprevent damage to your vehicle.Making very sharp turns couldcause the trailer to contact thevehicle.

Make wider turns than normal whentowing, so trailer will not go over softshoulders, over curbs, or strike roadsigns, trees, or other objects.Always signal turns well in advance.Do not steer or brake suddenly.

Driving on Grades

Reduce speed and shift to a lowergear before starting down a long orsteep downhill grade. If the

transmission is not shifted down, thebrakes may overheat and result inreduced braking efficiency.

The vehicle can tow in D (Drive).Shift the transmission to a lowergear if the transmission shifts toooften under heavy loads and/or hillyconditions.

When towing at higher altitudes,engine coolant will boil at a lowertemperature than at lower altitudes.If the engine is turned offimmediately after towing at highaltitude on steep uphill grades, thevehicle could show signs similar toengine overheating. To avoid this,let the engine run, preferably onlevel ground, with the transmissionin P (Park) for a few minutes beforeturning the engine off. If theoverheat warning comes on, seeEngine Overheating 0 305.

Parking on Hills

{ Warning

To prevent serious injury or death,always park your vehicle andtrailer on a level surface whenpossible.

When parking your vehicle and yourtrailer on a hill:

1. Press the brake pedal, but donot shift into P (Park) yet. Turnthe wheels into the curb iffacing downhill or into traffic iffacing uphill.

2. Have someone place chocksunder the trailer wheels.

3. When the wheel chocks are inplace, gradually release thebrake pedal to allow the chocksto absorb the load of the trailer.

4. Reapply the brake pedal. Thenapply the parking brake andshift into P (Park).

5. Release the brake pedal.

Leaving After Parking on a Hill

1. Apply and hold the brakepedal.

. Start the engine.

. Shift into a gear.

. Release the parking brake.

2. Let up on the brake pedal.

3. Drive slowly until the trailer isclear of the chocks.

4. Stop and have someone pickup and store the chocks.

Maintenance when TrailerTowing

The vehicle needs service moreoften when used to tow trailers. SeeMaintenance Schedule 0 361. It isespecially important to check theautomatic transmission fluid, engineoil, axle lubricant, belts, coolingsystem, and brake system beforeand during each trip.

Check periodically that all nuts andbolts on the trailer hitch are tight.

Trailering is different than justdriving the vehicle by itself.Trailering means changes inhandling, acceleration, braking,durability, and fuel economy.Successful, safe trailering takescorrect equipment, and it has to beused properly.

The following information has manytime-tested, important trailering tipsand safety rules. Many of these areimportant for your safety and that ofyour passengers. Read this sectioncarefully before pulling a trailer.

Trailer Weight

{ Warning

Never exceed the towing capacityfor your vehicle.

Safe trailering requires monitoringthe weight, speed, altitude, roadgrades, outside temperature,dimensions of the front of the trailer,and how frequently the vehicle isused to tow a trailer.

Trailer Weight Ratings

When towing a trailer, the combinedweight of the vehicle, vehiclecontents, trailer, and trailer contentsmust be below all of the maximumweight ratings for the vehicle,including:

. GCWR: Gross Combined WeightRating

. GVWR: Gross Vehicle WeightRating

. Maximum Trailer Weight Rating

. GAWR-RR: Gross Axle WeightRating-Rear

. Maximum Trailer Tongue WeightRating

See "Trailer Brakes" later in thissection to determine if brakes arerequired based on your trailer'sweight.

The only way to be sure the weightis not exceeding any of theseratings is to weigh the tow vehicleand trailer combination, fully loadedfor the trip, getting individualweights for each of these items.

Driving and Operating 255

{ Warning

You and others could be seriouslyinjured or killed if the trailer is tooheavy or the trailer brakes areinadequate for the load. Thevehicle may be damaged, and therepairs would not be covered bythe vehicle warranty.

Only tow a trailer if all the steps inthis section have been followed.Ask your dealer for advice andinformation about towing a trailer.

Gross Combined WeightRating (GCWR)

GCWR is the total allowable weightof the completely loaded vehicleand trailer including any fuel,passengers, cargo, equipment, andaccessories. Do not exceed theGCWR for your vehicle. The GCWRfor the vehicle is on the Tow RatingChart following.

To check that the weight of thevehicle and trailer are within theGCWR for the vehicle, follow thesesteps:

. Start with the "curb weight" fromthe trailering information label

. Add the weight of the trailerloaded with cargo and ready forthe trip

. Add the weight of all passengers

. Add the weight of all cargo in thevehicle

. Add the weight of hitch hardwaresuch as a draw bar, ball, loadequalizer bars, or sway bars

. Add the weight of anyaccessories or aftermarketequipment added to the vehicle

The resulting weight cannot exceedthe GCWR value shown on theTrailering Information Label.

The gross combined weight canalso be confirmed by weighing thetruck and trailer on a public scale.The truck and trailer should beloaded for the trip with passengersand cargo.

Gross Vehicle WeightRating (GVWR)

For information about the vehicle'smaximum load capacity, see VehicleLoad Limits 0 205. When calculatingthe GVWR with a trailer attached,the trailer tongue weight must beincluded as part of the weight thevehicle is carrying.

Maximum Trailer Weight

Use the tow rating chart todetermine how much the trailer canweigh, based on the vehicle modeland options.

6500 4WD Allison 2700 4:30 (1) 11 818 kg (26,000 lb)* The Gross Combined Weight Rating (GCWR) is the totally allowable weight of the completely loaded vehicle andtrailer including passengers, cargo equipment and conversions. The GCWR for the vehicle should not be exceeded.(1) Maximum Trailer Weight cannot be provided because total vehicle weight is unknown.(2) Choose an appropriate hitch and load the truck and trailer within the limits of GCWR, GVWR, and RGAWR.

Trailer Tongue Weight

The trailer tongue weight contributesto the Gross Vehicle Weight (GVW).GVW includes the CURB WEIGHTof your vehicle, any passengers,cargo, equipment and the trailertongue weight. Vehicle options,passengers, cargo, and equipmentreduce the maximum allowable

tongue weight the vehicle can carry,which also reduces the maximumallowable trailer weight.

Trailer Load Balance

The correct trailer load balancemust be maintained to ensure trailerstability. Incorrect load balance is aleading cause of trailer sway.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Driving and Operating 257

The trailer tongue weight (1) shouldbe 10–15% and fifth-wheel orgooseneck kingpin weight should be15–25% of the total loaded trailerweight (2). Some specific trailertypes, such as boat trailers, falloutside of this range. Always referto the trailer owner’s manual for therecommended trailer tongue weightfor each trailer. Never exceed themaximum loads for your vehicle,hitch and trailer.

The trailer load balance percentageis calculated as: weight (1) dividedby weight (2) times 100.

After loading the trailer, separatelyweigh the trailer and then the trailertongue and calculate the trailer loadbalance percentage to see if theweights and distribution areappropriate for your vehicle. If thetrailer weight is too high, it may bepossible to transfer some of thecargo into your vehicle. If the trailertongue weight is too high or too low,it may be possible to rearrangesome of the cargo inside of thetrailer.

Do not exceed the maximumallowable tongue weight for yourvehicle. Use the shortest hitchextension available to position thehitch ball closer to your vehicle. Thiswill help reduce the effect of thetrailer tongue weight on the trailerhitch and the rear axle.

Rear Gross Axle Weight Rating(GAWR-RR)

The GAWR-RR is the total weightthat can be supported by the rearaxle of the vehicle. Do not exceedthe GAWR-RR for the vehicle, withthe tow vehicle and trailer fullyloaded for the trip including theweight of the trailer tongue. If usinga weight-distributing hitch, do notexceed the GAWR-RR beforeapplying the weight distributionspring bars.

Towing Equipment

Hitches

Always use the correct hitchequipment for your vehicle.Crosswinds, large trucks going by,and rough roads can affect thetrailer and the hitch.

Proper hitch equipment for yourvehicle helps maintain control of thevehicle-trailer combination. Manytrailers can be towed using aweight-carrying hitch which has acoupler latched to the hitch ball, or atow eye latched to a pintle hook.Other trailers may require a

weight-distributing hitch that usesspring bars to distribute the trailertongue weight between your vehicleand trailer axles. Fifth-wheel andgooseneck hitches may alsobe used.

Avoid sharp turns when using astep-bumper hitch to preventdamage. Make wider turns toprevent contact between your trailerand your bumper.

Tires. Do not tow a trailer while using a

compact spare tire on thevehicle.

. Tires must be properly inflated tosupport loads while towing atrailer. See Tires 0 331 forinstructions on proper tireinflation.

Safety Chains

Always attach chains between thevehicle and the trailer, and attachthe chains to the holes on the trailerhitch platform. Instructions about

safety chains may be provided bythe hitch manufacturer or by thetrailer manufacturer.

Cross the safety chains under thetongue of the trailer to help preventthe tongue from contacting the roadif it becomes separated from thehitch. Always leave just enoughslack so the combination can turn.Never allow safety chains to drag onthe ground.

Trailer Brakes

Loaded trailers over 675 kg (1,500lb) must be equipped with brakesystems and with brakes for eachaxle. Trailer braking equipmentconforming to Canadian StandardsAssociation (CSA) requirementCAN3-D313, or its equivalent, isrecommended.

State or local regulations mayrequire trailers to have their ownbraking system if the loaded weightof the trailer exceeds certainminimums that can vary from stateto state. Read and follow theinstructions for the trailer brakes sothey are installed, adjusted, and

maintained properly. Never attemptto tap into your vehicle's hydraulicbrake system. If you do, both thevehicle anti-lock brakes and thetrailer brakes may not function,which could result in a crash.

Auxiliary Battery

If equipped, the vehicle's auxiliarybattery can be used to supplyelectrical power to additionalequipment.

Caution

To prevent draining the auxiliarybattery, always turn off electricalequipment when not in use anddo not use any equipment thatmay exceed themaximum amperage rating of30 amps.

Tow/Haul Mode

For instructions on how to enterTow/Haul mode, see Tow/HaulMode 0 227.

Tow/Haul assists when pulling aheavy trailer or a large orheavy load.

Tow/Haul Mode is designed to bemost effective when the vehicle andtrailer combined weight is at least75% of the vehicle's GrossCombined Weight Rating (GCWR).See “Weight of the Trailer” underTrailer Towing 0 254.

Tow/Haul Mode is most useful whentowing a heavy trailer or carrying alarge or heavy load:

. through rolling terrain

. in stop-and-go traffic

. in busy parking lots

Operating the vehicle in Tow/HaulMode when lightly loaded or nottowing will not cause damage;however, it is not recommended andmay result in unpleasant engine andtransmission driving characteristicsand reduced fuel economy.

Integrated Trailer BrakeControl System

The vehicle may have an IntegratedTrailer Brake Control (ITBC) systemfor use with electric trailer brakes ormost electric over hydraulic trailerbrake systems. These instructionsapply to both types of electric trailerbrakes.

This symbol is on the Trailer BrakeControl Panel on vehicles with anITBC system. The power output tothe trailer brakes is proportional tothe amount of vehicle braking. Thisavailable power output to the trailerbrakes can be adjusted to a widerange of trailering situations.

The ITBC system is integrated withthe vehicle’s anti-lock brake system.In trailering conditions that causethe vehicle’s anti-lock brake systemto activate, power sent to thetrailer's brakes will be automaticallyadjusted to minimize trailer wheellock-up. This does not imply that thetrailer has anti-lock brakes.

If the vehicle’s brake or anti-lockbrake systems are not functioningproperly, the ITBC system may notfunction fully or at all. Make sure all

of these systems are fullyoperational to allow the ITBCsystem to function properly.

The ITBC system is poweredthrough the vehicle's electricalsystem. Turning the ignition off willalso turn off the ITBC system. TheITBC system is fully functional onlywhen the ignition is in ON/RUN.

{ Warning

Connecting a trailer that has anair brake system may result inreduced or complete loss of trailerbraking, including increasedstopping distance or trailerinstability which could result inserious injury, death, or propertydamage.

Trailer Tires

Special Trailer (ST) tires differ fromvehicle tires. Trailer tires aredesigned with stiff sidewalls to helpprevent sway and to support heavyloads. These features can make itdifficult to determine if the trailer tirepressures are low only based on avisual inspection.

Always check all trailer tirepressures before each trip when thetires are cool. Low trailer tirepressure is a leading cause of trailertire blow-outs.

Trailer tires deteriorate over time.The trailer tire sidewall will show theweek and year the tire wasmanufactured. Many trailer tiremanufacturers recommendreplacing tires more than sixyears old.

Overloading is another leadingcause of trailer tire blow-outs. Neverload your trailer with more weightthan the tires are designed tosupport. The load rating is locatedon the trailer tire sidewall.

Always know the maximum speedrating for the trailer tires beforedriving. This may be significantlylower than the vehicle tire speedrating. The speed rating may be onthe trailer tire sidewall. If the speedrating is not shown, the defaulttrailer tire speed rating is 105 km/h(65 mph).

installed. The vehicle can bedamaged if either the front or rearaxle ratings or the Gross VehicleWeight Rating (GVWR) areexceeded.

The plow the vehicle can carrydepends on many things, such as:

. The options the vehicle camewith, and the weight of thoseoptions.

. The weight and number ofpassengers to be carried.

. The weight of items added to thevehicle, like a tool box ortruck cap.

. The total weight of anyadditional cargo to be carried.

For example, if the snow plowweighs 318 kg (700 lb), the totalweight of all occupants and cargoinside the cab should not exceed135 kg (300 lb). This means that youmay only be able to carry onepassenger. Even this may be too

much if there is other equipmentalready adding to the weight of thevehicle.

To safely carry a snow plow on thevehicle:

. Follow all aftermarket snow plowmanufacturer’s instructions forthe operation and transportationof the snow plow.

. With a snow plow attached, theengine coolant temperaturegauge may show a highertemperature than while drivingwithout one. The snow plowcould block the airflow to theradiator. This could be morenoticeable as vehicle speedincreases. At speeds above72 km (45 mph), this may causethe engine coolant to overheat.

. To increase the airflow, move thesnow plow blade postion.

. If driving more than 24 km(15 mi), angle the plow bladeposition.

. Make sure the weight on thefront and rear axles does notexceed the axle rating for each.

. For the front axle, if more cargoor passengers must be carried,appropriate counter ballast mustbe installed rear of the rear axle.Counter ballast must be properlysecured so it will not moveduring driving.

. Rear ballast may be required toensure a proper front and rearweight distribution ratio, eventhough the actual weight at thefront axle may be less than thefront axle rating.

. The snow plow manufacturer orinstaller can assist indetermining the amount of rearballast required, to help makesure the snow plow/vehiclecombination does not exceedthe GVW rating, the front andrear axle ratings, and the frontand rear weight distribution ratio.

. The total vehicle must notexceed the GVW rating.

Front axle reserve capacity is thedifference between the Gross AxleWeight Rating (GAWR) and the frontaxle weight of the vehicle with fullfuel and passengers. This is theamount of weight that can be addedto the front axle before reaching thefront GAWR.

United States

Canada

The front axle reserve capacity forthe vehicle is in the lower rightcorner of the Certification/Tire label.

To calculate the amount of weightany front accessory, such as a snowplow, is adding to the front axle, usethis formula:

(W x (A +W.B.)) /W.B.= Weight theaccessory is adding to thefront axle.

Where:W = Weight of added accessoryA = Distance that the accessoryis in front of the front axleW.B. = Vehicle Wheelbase

For example, adding a 318 kg(700 lb) snow plow actually addsmore than 318 kg (700 lb) to thefront axle. Using the formula, if thesnow plow is 122 cm (4 ft) in front ofthe front axle and the wheelbase is305 cm (10 ft), then:

W = 318 kg (700 lb)A = 122 cm (4 ft)

Driving and Operating 269

W.B. = 305 cm (10 ft)

(W x (A +W.B.)/W.B. =(318 x (122 + 305))/305 = 445 kg(980 lb)

This means if the front axle reservecapacity is more than 445 kg(980 lb), the snow plow could beadded without exceeding thefront GAWR.

Heavier equipment can be added onthe front of the vehicle if less cargoor fewer passengers are carried,or by positioning cargo toward therear. This reduces the load on thefront. However, the front GAWR,rear GAWR, and Gross VehicleWeight Rating (GVWR) must neverbe exceeded.

Diesel Particulate FilterCleaning During PTOOperation

This feature is only available onFleet and Commercial vehicles. Toverify that the vehicle has thisfeature, see www.gmupfitter.com tocontact the GM Upfitter IntegrationGroup for assistance.

If equipped, this feature allows formanual cleaning/regeneration of theDiesel Particulate Filter (DPF) whenit is unable to clean itself. It may benecessary to perform a manualregeneration if driving conditions —such as extended slow speed,stop-and-go traffic, extended idles,short drive cycles, or stationary PTOoperation — prevent DPFself-cleaning.

Manual regeneration can only beused when the DPF has become atleast 90% full. At 100% full, it willattempt to automatically self-clean ifproper driving conditions are met.The DPF will clean itself if the

vehicle can be driven above50 km/h (30 mph) for about30 minutes.

Manual regeneration can be usedduring a stationary PTO session.However it is strongly recommendedthat the exhaust filter be cleanedbefore continuous PTO. If manualregeneration is operatingconcurrently with PTO then the PTOsystem will retain control of theengine speed. Low PTO enginespeeds will cause regeneration totake longer. To initiate a manualDPF regeneration, see “ManualRegeneration of Diesel ParticulateFilter” under Diesel Particulate Filter.

Engine OilTo ensure proper engineperformance and long life, carefulattention must be paid to engine oil.Following these simple, butimportant steps will help protectyour investment:

. Use engine oil approved to theproper specification and of theproper viscosity grade. See“Selecting the Right Engine Oil”in this section.

. Check the engine oil levelregularly and maintain theproper oil level. See “CheckingEngine Oil” and “When to AddEngine Oil” in this section.

. Change the engine oil at theappropriate time. See Engine OilLife System 0 298.

. Always dispose of engine oilproperly. See “What to Do withUsed Oil” in this section.

Checking Engine Oil

Check the engine oil level regularly,every 650 km (400 mi), especiallyprior to a long trip. The engine oildipstick handle is a loop. SeeEngine Compartment Overview0 294 for the location.

{ Warning

The engine oil dipstick handlemay be hot; it could burn you.Use a towel or glove to touch thedipstick handle.

If a low oil Driver Information Center(DIC) message displays, check theoil level.

Follow these guidelines:

. To get an accurate reading, parkthe vehicle on level ground.Check the engine oil level afterthe engine has been off for atleast two hours. Checking the

296 Vehicle Care

engine oil level on steep gradesor too soon after engine shutoffcan result in incorrect readings.Accuracy improves whenchecking a cold engine prior tostarting. Remove the dipstickand check the level.

. If unable to wait two hours, theengine must be off for at least15 minutes if the engine iswarm, or at least 30 minutes ifthe engine is not warm. Pull outthe dipstick, wipe it with a cleanpaper towel or cloth, then push itback in all the way. Remove itagain, keeping the tip down, andcheck the level.

When to Add Engine Oil

If the oil is below the cross-hatchedarea at the tip of the dipstick andthe engine has been off for at least

15 minutes, add 1 L (1 qt) of therecommended oil and then recheckthe level. See “Selecting the RightEngine Oil” later in this section foran explanation of what kind of oil touse. For engine oil crankcasecapacity, see Capacities andSpecifications 0 408.

Caution

Do not add too much oil. Oillevels above or below theacceptable operating rangeshown on the dipstick are harmfulto the engine. If the oil level isabove the operating range (i.e.,the engine has so much oil thatthe oil level gets above thecross-hatched area that showsthe proper operating range), theengine could be damaged. Drainthe excess oil or limit driving ofthe vehicle, and seek a serviceprofessional to remove theexcess oil.

See Engine Compartment Overview0 294 for the location of the engineoil fill cap.

Be sure to add enough oil to put thelevel somewhere in the properoperating range. Push the dipstickall the way back in when through.

Selecting the Right Engine Oil

Specification

Oils designated as API CJ-4 orCK-4 are required for the vehicle.The CJ-4 or CK-4 designation canappear either alone or incombination with other AmericanPetroleum Institute (API)designations, such as API CJ-4/SL.These letters show API levels ofquality.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Vehicle Care 297

American Petroleum Institute (API)Symbol

This doughnut-shaped logo(symbol) is used on most oilcontainers to help you select thecorrect oil. It means that the oil hasbeen certified by the AmericanPetroleum Institute.

Look for this on the oil container,and use only those oils that displaythis logo.

Caution

Use only engine oils that have thedesignation CJ-4 or CK-4 for thediesel engine. Failure to use therecommended oil can damage theDPF and result in engine damagenot covered by the vehiclewarranty.

Viscosity Grade

Use SAE 15W-40 viscosity gradeengine oil.

When it is very cold, below −18 °C(0 °F), use SAE 5W-40 to improvecold starting. These numbers on theoil container show its viscosity,or thickness.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

298 Vehicle Care

When selecting an oil of theappropriate viscosity grade, alwaysselect an oil of the correctspecification. See “Specification”earlier in this section.

Engine Oil Additives/EngineOil Flushes

Do not add anything to the oil. Therecommended oils with the APIservice symbol are all that isneeded for good performance andengine protection.

Engine oil system flushes are notrecommended and could causeengine damage not covered by thevehicle warranty.

What to Do with Used Oil

Used engine oil contains certainelements that can be unhealthy foryour skin and could even causecancer. Do not let used oil stay onyour skin for very long. Clean yourskin and nails with soap and water,or a good hand cleaner. Wash orproperly dispose of clothing or rags

containing used engine oil. See themanufacturer's warnings about theuse and disposal of oil products.

Used oil can be a threat to theenvironment. If you change yourown oil, be sure to drain all the oilfrom the filter before disposal. Neverdispose of oil by putting it in thetrash or pouring it on the ground,into sewers, or into streams orbodies of water. Recycle it by takingit to a place that collects used oil.

Engine Oil Life System

When to Change Engine Oil

This vehicle has a computer systemthat indicates when to change theengine oil and filter. This is basedon a combination of factors whichinclude engine revolutions, enginetemperature, and miles driven.Based on driving conditions, themileage at which an oil change isindicated can vary considerably. Forthe oil life system to work properly,the system must be reset every timethe oil is changed.

On some vehicles, when the systemhas calculated that oil life has beendiminished, a CHANGE ENGINEOIL SOON message comes on toindicate that an oil change isnecessary. Change the oil as soonas possible within the next 1 000 km(600 mi). It is possible that, if drivingunder the best conditions, the oil lifesystem might indicate that an oilchange is not necessary for up to ayear. The engine oil and filter mustbe changed at least once a yearand, at this time, the system mustbe reset. For vehicles without theCHANGE ENGINE OIL SOONmessage, an oil change is neededwhen the REMAINING OIL LIFEpercentage is near 0%. Your dealerhas trained service people who willperform this work and reset thesystem. It is also important to checkthe oil regularly over the course ofan oil drain interval and keep it atthe proper level.

If the system is ever resetaccidentally, the oil must bechanged at 5 000 km (3,000 mi)

since the last oil change.Remember to reset the oil lifesystem whenever the oil is changed.

How to Reset the Engine OilLife System

Reset the system whenever theengine oil is changed so that thesystem can calculate the nextengine oil change. Always reset theengine oil life to 100% after every oilchange. It will not reset itself. Toreset the engine oil life system:

1. Display the REMAINING OILLIFE on the DIC. If the vehicledoes not have DIC buttons, thevehicle must be in P (Park) toaccess this display.See Driver Information Center(DIC) (Base Level) 0 119 orDriver Information Center (DIC)(Uplevel) 0 120.

2. Press and hold V, or the tripodometer reset stem if thevehicle does not have DICbuttons, for several seconds.The oil life will changeto 100%.

The oil life system can also be resetas follows:

1. Display the REMAINING OILLIFE on the DIC.See Driver Information Center(DIC) (Base Level) 0 119 orDriver Information Center (DIC)(Uplevel) 0 120.

2. Fully press the acceleratorpedal slowly three times withinfive seconds.

3. Display the REMAINING OILLIFE on the DIC. If the displayshows 100%, the system isreset.

If the vehicle has a CHANGEENGINE OIL SOON message and itcomes back on when the vehicle isstarted and/or the REMAINING OILLIFE is near 0%, the engine oil lifesystem has not been reset. Repeatthe procedure.

If the DIC message comes on withno sign of steam, try this for aminute or so:

1. In heavy traffic, let the engineidle in N (Neutral) whilestopped. If it is safe to do so,pull off the road, shift toP (Park) or N (Neutral), and letthe engine idle.

2. Turn on the heater to full hot atthe highest fan speed andopen the window as necessary.

If the vehicle no longer has theoverheat warning, the vehicle canbe driven. Just to be safe, driveslower for about 10 minutes. If thewarning does not come back on,

drive normally and have the coolingsystem checked for proper fill andfunction.

If the warning continues, pull over,stop, and park the vehicleright away.

If there is still no sign of steam andthe vehicle is equipped with anengine driven cooling fan, pushdown the accelerator until theengine speed is about twice as fastas normal idle speed for at leastfive minutes while the vehicle isparked. If the warning is still there,turn off the engine and get everyoneout of the vehicle until it cools down.

The decision may be made not to tiltthe hood, but to get service helpright away.

Engine FanThe vehicle has a clutched enginecooling fan. When the clutch isengaged, the fan spins faster toprovide more air to cool the engine.In most everyday driving conditions,the fan is spinning slower and theclutch is not fully engaged. This

improves fuel economy and reducesfan noise. Under heavy vehicleloading, trailer towing, and/or highoutside temperatures, the fan speedincreases as the clutch more fullyengages, so an increase in fannoise may be heard. This is normaland should not be mistaken as thetransmission slipping or makingextra shifts. It is merely the coolingsystem functioning properly. The fanwill slow down when additionalcooling is not required and theclutch disengages.

This fan noise may also be heardwhen starting the engine. It will goaway as the fan clutch partiallydisengages.

heard. A fluid loss in this systemcould indicate a problem. Have thesystem inspected and repaired.

How to Check Power SteeringFluid

The fluid level should be betweenthe MIN HOT and MAX HOT levelson the reservoir if the fluid is hotwhen checked. If the fluid is coldwhen checked, the fluid level shouldbe between the MIN COLD andMAX COLD levels on the reservoir.

To check the power steering fluid:

1. Tilt the hood open. See Hood0 291.

2. Check to see if the fluid level isat or above the MIN HOT leveland below the MAX HOT levelif the fluid is hot, or if the fluidlevel is at or above the MINCOLD level and below theMAX COLD line if the fluidis cold.

3. If the fluid is low, wipe the capand the top of the reservoirclean.

4. Turn the cap counterclockwiseand remove.

5. Fill the reservoir to theindicated MAX COLD or MAXHOT level.

6. Replace the cap and verify it issecure.

7. Tilt the hood closed. See Hood0 291.

What to Use

Washer Fluid

What to Use

When windshield washer fluid needsto be added, be sure to read themanufacturer's instructions beforeuse. Use a fluid that has sufficientprotection against freezing in anarea where the temperature may fallbelow freezing.

Adding Washer Fluid

The vehicle has a low washer fluidmessage on the DIC that comes onwhen the washer fluid is low. Themessage is displayed for15 seconds at the start of eachignition cycle. When the WASHERFLUID LOW ADD FLUID messagedisplays, washer fluid will need tobe added to the windshield washerfluid reservoir.

Open the cap with the washersymbol on it. Add washer fluid untilthe tank is full. See EngineCompartment Overview 0 294 forreservoir location.

Caution

. Do not use washer fluid thatcontains any type of waterrepellent coating. This cancause the wiper blades tochatter or skip.

. Do not use engine coolant(antifreeze) in thewindshield washer. It candamage the windshieldwasher system and paint.

. Do not mix water withready-to-use washer fluid.Water can cause the

solution to freeze anddamage the washer fluidtank and other parts of thewasher system.

. When using concentratedwasher fluid, follow themanufacturer instructions foradding water.

. Fill the washer fluid tankonly three-quarters full whenit is very cold. This allowsfor fluid expansion iffreezing occurs, which coulddamage the tank if it iscompletely full.

Downhill Operation

{ Warning

To prevent property damage,personal injury, and/or death, donot attempt to gear down if theengine is at or near maximumspeed (rpm). Under theseconditions, it will be impossible toshift into a lower gear and couldresult in possible vehicle runaway.

Always descend hills with extremecare, relying mainly on the enginebraking effect to control vehiclespeed. Heed warning signs postedfor any grade. Stop and checkbrakes for condition and adjustmentat available pull off areas beforestarting a descent.

Observe the following precautions:

. Never coast downhill. Servicebrakes alone should not be usedto control speed on majordowngrades. Brakes will fadefrom overuse.

. Use the service brakes inaddition to other ways of slowingdown the vehicle. Whendescending long gradesrequiring use of the brakes,short applications (three tofive seconds in duration) shouldbe made rather than long,continuous applications. Thisminimizes temperature rise andbrake fade.

Hydraulic Brakes

{ Warning

The brake system might not beworking properly if the brakesystem warning light is on.Driving with the brake systemwarning light on can lead to a

(Continued)

Warning (Continued)

crash. If the light is still on afterthe vehicle has been pulled offthe road and carefully stopped,have the vehicle towed forservice.

The hydraulic brake systemincorporates standard braking,Antilock Braking (ABS), andAutomatic Traction Control (ATC)into one fully integrated hydraulicbrake system. With the hydraulicbrake system, braking energy isstored, similar to an air brakesystem, resulting in faster responsetimes and shorter stoppingdistances. This is accomplishedusing motor/pump assemblies thatpressurize the system by pumpingbrake fluid into accumulators. Thisis similar to the air compressor of anair brake system pressurizing the airtanks.

The system includes a mastercylinder that provides the normalpedal “feel” and transfers the pedal

force, via brake fluid, to the maincomponents of the hydraulic brakesystem.

The motor/pumps will runmomentarily with the ignition on oroff to maintain accumulatorpressure. Therefore, whenever thebrake pedal is pressed when theignition is off, the motor/pumps maybe heard.

Split System Feature

{ Warning

To prevent property damage,personal injury, and/or death,if part of the brake system fails,reduce speed and employ safedriving practices as stoppingdistance may increase under thefailed condition since only onesection of the brake system isoperating. Have the brake systemrepaired immediately. Loss ofbraking capability could cause acrash.

The system is divided into twoseparate but identical channels: theprimary channel (controls front axle)and the secondary channel (controlsrear axle). The master cylinderprovides brake lines that are routedto the front and rear brake channels.

With the split brake system, thevehicle should have reasonablebrake control should one of the twochannels fail. If one of the motor/pump related systems fails, youmay not detect any difference in thefeel of the pedal, but with a defect inthe master cylinder circuit, you mayexperience a longer pedal stroke toattain desired stopping. With anysystem failure, one of the instrumentcluster warning indicators willturn on.

Hydraulic Brake BoosterSystem

{ Warning

To prevent property damage,personal injury, and/or death,if part of the brake system fails,reduce speed and employ safedriving practices as stoppingdistance may increase under thefailed condition since only onesection of the brake system isoperating. Have the brake systemrepaired immediately. Loss ofbraking capability could cause acrash.

The system receives fluid pressurefrom the power steering pump toprovide power assist during braking.

The hydraulic booster has a backuppump which will provide hydraulicboost at a reduced rate if the normalsource of fluid is interrupted. Thesignal for operation of the backuppump comes from the flow switch.If normal flow is interrupted, the flow

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Vehicle Care 311

switch will close and activate therelay, which will turn on thebackup pump.

Under normal operating conditions,noise of the fluid flowing through thebooster may be heard whenever thebrake is applied. This is normal andshould be no reason for concern.

If braking performance or pedalresponse becomes very poor, evenwhen the pedal is strongly applied,this may indicate the presence of airin the hydraulic system or fluidleakage. Safely stop the vehicle assoon as possible and have thevehicle serviced right away.

Brake Fluid

The brake master cylinder reservoiris filled with GM approved DOT 3brake fluid as indicated on the

reservoir cap. See EngineCompartment Overview 0 294 forthe location of the reservoir.

Checking Brake Fluid

With the vehicle in P (Park) on alevel surface, the brake fluid levelshould be between the minimumand maximum marks on the brakefluid reservoir.

There are only two reasons why thebrake fluid level in the reservoir maygo down:

. Normal brake lining wear. Whennew linings are installed, thefluid level goes back up.

. A fluid leak in the brakehydraulic system. Have thebrake hydraulic system fixed.With a leak, the brakes will notwork well.

Always clean the brake fluidreservoir cap and the area aroundthe cap before removing it.

Do not top off the brake fluid.Adding fluid does not correct a leak.If fluid is added when the linings areworn, there will be too much fluid

when new brake linings areinstalled. Add or remove fluid, asnecessary, only when work is doneon the brake hydraulic system.

{ Warning

If too much brake fluid is added, itcan spill on the engine and burn,if the engine is hot enough. Youor others could be burned, andthe vehicle could be damaged.Add brake fluid only when work isdone on the brake hydraulicsystem.

When the brake fluid falls to a lowlevel, the brake warning light comeson. See Brake System WarningLight 0 115.

Brake fluid absorbs water over timewhich degrades the effectiveness ofthe brake fluid. Replace brake fluidat the specified intervals to preventincreased stopping distance. SeeMaintenance Schedule 0 361.

What to Add

Use only GM approved DOT 3brake fluid from a clean, sealedcontainer. See RecommendedFluids and Lubricants 0 398.

{ Warning

The wrong or contaminated brakefluid could result in damage to thebrake system. This could result inthe loss of braking leading to apossible injury. Always use theproper GM approved brake fluid.

Caution

If brake fluid is spilled on thevehicle's painted surfaces, thepaint finish can be damaged.Immediately wash off any paintedsurface.

It is not necessary to regularlycheck rear axle fluid unless a leak issuspected or an unusual noise isheard. A fluid loss could indicate aproblem. Have it inspected andrepaired.

All axle assemblies are filled byvolume of fluid during production.They are not filled to reach a certainlevel. When checking the fluid levelon any axle, variations in thereadings can be caused by factoryfill differences between the minimumand the maximum fluid volume.Also, if a vehicle has just beendriven before checking the fluid

level, it may appear lower thannormal because fluid has traveledout along the axle tubes and hasnot drained back to the sump area.Therefore, a reading takenfive minutes after the vehicle hasbeen driven will appear to have alower fluid level than a vehicle thathas been stationary for an hour ortwo. The rear axle assembly mustbe supported on a flat, level surfaceto get a true reading.

Warning (Continued)

and new loads or inflationpressures could be placed onthe same vehicle.

Maintaining the correct amountof air pressure is a veryimportant maintenance practiceto ensure safe vehicle operationand long life for the tires.

Failure to maintain correctinflation pressure may result insudden tire destruction,improper vehicle handling, andmay cause rapid and irregulartire wear. Therefore, inflationpressures should be checkeddaily and always beforelong-distance trips.

Underinflation

Do not allow tires to becomeunderinflated. Increased flexingdue to underinflation causesheat buildup within the tire

components. This leads toreduced strength, breakdown ofthe rubber compounds andpossible separation of the tirecomponents (such as ply andtread separation and reducedretreadability).

Underinflation is also theprimary cause of blowouts. Inaddition, low inflation causes anincrease in rolling resistance.This results in reduced fuelmileage, a loss in tread life, anduneven wear due to increasedtread movement. To determineproper inflation, refer to the tireinflation range stated on the tiresidewall and the tiremanufacturer’s tireload-pressure charts.

Checking Inflation

Check the tires daily and alwaysbefore long-distance trips

Follow the tire manufacturer’srecommended cold inflationpressure for the tire size, type,

load range (ply rating), and axleloading typical for youroperation. Each steer axle tireload will equal one-half the steeraxle loading; each drive tire loadwill be one-quarter the axleloading, if fitted with four tires.

Always check the inflationpressure when the tires are cold.Never bleed air from hot tires torelieve normal pressure buildup.Normal increases in pressureduring operation will be 69 to103 kPa (10 to 15 psi), which isallowable in truck tires. Tires onthe same axle should have thesame air pressure as thecorresponding other tire(s) onthat axle. All tires on thesteering axle should be within21 kPa (3 psi) of each other. Alldrive axle tires should be within34 kPa (5 psi) of each other.

To minimize rim corrosion, it isimportant to keep moisture fromthe inside of tires and proper

equipment and correctprocedures to mount orremove tires and wheels.

Check the condition of the tiresfor abnormal wear patterns andproper inflation pressures. Cutor broken tire casings must berepaired or replaced.

Check the tread depth and tireinflation. Check to see if thetread is evenly worn. Minimumtread depth is 3 mm (4/32 in) onsteering tires. Look for cuts orother damage to the tread orsidewalls. Check for missing,broken, or damaged valve capand stem.

Check that the dual wheels,if equipped, are evenlyseparated, and that the tires arenot touching one another.

Tires should be inspected for thefollowing conditions. If any arepresent, the tire should beremoved and repaired,retreaded, or scrapped as thecondition indicates.

. Any blister, bump, or raisedportion anywhere on thesurface of the tire tread orsidewall (other than a bumpmade by a repair). Theseindicate the start of internalseparation.

. Any cut that reaches to thebelt or ply cords or any cutthat is large enough to growin size and depth.

. Any nail or puncturing object.

. If any stone or object is heldby a tread groove and isstarting to drill into the treadbase, remove the object.

Proper tire inflation, toe-inadjustment, loads, and roadspeeds are important factors

governing tire life, steering ease,maneuverability, fuel economy,and ride quality.

Tire RotationTires should be rotated every12 000 km (7,500 mi). SeeMaintenance Schedule 0 361.

Tires are rotated to achieve auniform wear for all tires. Thefirst rotation is the mostimportant.

Anytime unusual wear isnoticed, rotate the tires as soonas possible, check for proper tireinflation pressure, and check fordamaged tires or wheels. If theunusual wear continues after therotation, check the wheelalignment.See When It Is Time for NewTires 0 337 and WheelReplacement 0 339.

Dual Tire Rotation

When the vehicle is new,or whenever a wheel, wheelbolt, or wheel nut is replaced orserviced, check the wheel nuttorque after 160, 1 600, and10 000 km (100, 1,000, and6,000 mi) of driving. For propertorque and wheel nut tighteninginformation, see “Wheel NutTorque” under Capacities andSpecifications 0 408.

The outer tire on a dual wheelsetup generally wears fasterthan the inner tire. Tires lastlonger and wear more evenly ifthey are rotated.See Tire Inspection 0 334 andTire Rotation 0 335. Also seeMaintenance Schedule 0 361.

{ Warning

If the vehicle is operated with atire that is underinflated, the tirecan overheat. An overheated tirecan lose air suddenly or catchfire. You or others could beinjured. Properly inflate all tires,including the spare.

See Tire Pressure 0 332, forinformation on proper tireinflation.

Use this rotation pattern whenrotating the tires (exceptpolished forged aluminumwheels).

Vehicles with polished forgedaluminum wheels have twounique wheels; an aluminumfront and rear outer wheels, andsteel rear inner wheels. Thealuminum wheels can only berotated from the front and rearouter positions. The steelwheels can only be rotated onthe rear inner positions.

Use this rotation pattern whenrotating the tires if the vehiclehas polished forged aluminumwheels. The steel spare wheelcan be used in any position inthe event of a flat tire. Analuminum spare wheel can beused in front or rear outerpositions only.

When installing dual wheels,check that the vent holes in theinner and outer wheels on eachside are lined up.

Adjust the front and rear tires tothe recommended inflationpressure on the Tire andLoading Information label afterthe tires have been rotated.See Tire Pressure 0 332 andVehicle Load Limits 0 205.

Check that all wheel nuts areproperly tightened. See “WheelNut Torque” under Capacitiesand Specifications 0 408.

{ Warning

Rust or dirt on a wheel, or on theparts to which it is fastened, canmake wheel nuts become looseafter time. The wheel could comeoff and cause a crash. Whenchanging a wheel, remove anyrust or dirt from places where thewheel attaches to the vehicle. Inan emergency, a cloth or a papertowel can be used; however, usea scraper or wire brush later toremove all rust or dirt.

Lightly coat the inner diameter ofthe wheel hub opening withwheel bearing grease after awheel change or tire rotation toprevent corrosion or rustbuild-up. Do not get grease onthe flat wheel mounting surfaceor on the wheel nuts or bolts.

Check that the spare tire, if thevehicle has one, is storedproperly.

When It Is Time for NewTiresTire Replacement

{ Warning

To prevent property damage,personal injury, and/or death, it isrecommended that you neverreplace vehicles tires with lowerroad speed rating. However, inthe event you should change/replace vehicle tires with those ofa lower road speed rating, it willbe necessary for you to take yourvehicle to the dealer to have theroad speed engine parameterchanged to match the new tirerating.

Retread tires are not recommendedfor use on steering axles of trucks.

. Front (Steering) Axle — Tiresmust be removed when the treadis worn to 3 mm (4/32 in) or less.Retread or rotate worn tires todrive position.

. Rear Axle — Tires must beremoved when the tread is wornto 2 mm (2/32 in).

If a rib tire is used on the front axleand lug or off-road type on the rearaxle positions:

. Front (Steering) Axle — Replacethe front tires when the tread isworn to 3 mm (4/32 in) or less.

. Rear Axle — Tires must beremoved when the tread is wornto 2 mm (2/32 in) or less. Tiresidentified with the wordregroovable molded on thesidewall can be regrooved.A minimum of 2.38 mm (3/32 in)of under tread must be left at thebottom of the grooves.

Never mix bias and radial tires onthis vehicle.

It is recommended for best overallperformance that only radial tires beused on this vehicle.

Never mix different tire sizes orconstructions on the same axle.

Tire replacement should be to tireswith GHG emission performance asgood, or better than tires originallyequipped on the vehicle. Consultwith the tire manufacturer for tirespecifications.

Replacement Tire Size and LoadRating

{ Warning

To prevent property damage,personal injury, and/or death, donot load tires beyond their ratedcapacity as this decreases tirelife, requiring more frequentreplacement of tires. Overloadingcreates an unsafe condition thatmay result in sudden air loss froma tire failure resulting in a crash.

The Tire/Certification Label found onthe driver-side door frame of yourvehicle, indicates the size of theoriginal equipment tires installed oneach axle of the vehicle.

1. Gross Weight Rating of theFront Axle

2. Tire Size for Front Axle3. Tire Size for Rear Axle4. Gross Weight Rating of the

Rear Axle

The Tire/Certification Label istypically found on the driver-sidedoor frame of the vehicle.It indicates the size of the originalequipment tires installed on eachaxle of the vehicle.

The load rating of the tires installedon your vehicle at the time ofproduction is at or in excess of theGross Axle Weight Rating (GAWR)on the Tire/Certification Label.When replacing the tires be sure the

replacement tire load rating (listedseparately in pounds and kilogramson the tire sidewall for single or dualapplications) multiplied by thenumber of tires on that axle is equalto or higher than the specified listedSteer Axle or Drive Axle GAWR.Failure to do so will adversely affectmaximum load-carrying capacity.Tires with the same sizespecifications do not always havethe same load specification. SeeVehicle Load Limits 0 205.

Dual Tires Matching

Dual tires should be matched usingtires of equivalent size. Tires whichdiffer more than 6 mm (1/4 in) indiameter or 19 mm (3/4 in) incircumference should not bemounted on the same dual wheelassembly.

Wear

Radial tires can exhibit three typesof normal wear patterns: even,erosion, or chamfer.

Even wear is a sign that the tire isbeing properly used and maintained.

Erosion wear has also been calledrolling wear, channel, or river wear.Erosion wear is found more often atfree rolling tires. This is anindication that the tire is being usedin a slow wearing operation. Whathappens is that the belt plies areheld very rigid and the tread is notallowed to distort as it passesthrough the contact area. Wear willonly occur at the edge of the tread.No corrective action is required.If erosion gets to be 2 mm (1/16 in)or more, the tire may be rotated to adrive axle.

Chamfer or shoulder wear with tiresinflated properly, is a normaltendency of most radial tire designs.If both inside and outside shouldersare wearing evenly around the tire,no further action is required.Overinflation is not effective incorrecting this effect.

Irregular Wear

If irregular wear is present, checkthe axle alignment, tire pressure,wheel balance, shock andsuspension component condition,and wheel bearing end play.

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

Vehicle Care 339

This condition not only shortens tirelife, but will adversely affect thehandling of your vehicle.

Rotating tires from one wheelposition to another is a way oftenused to even out many types ofirregular wear or to avoid italtogether. See Tire Rotation 0 335.

Irregular wear can be minimized by:

. Using the right inflation pressurefor the load being carried.

. Maintaining proper front wheelalignment especially toe-in tospecifications.

. Maintaining proper tire andwheel balance.

. Maintaining shock absorbersand suspension components.

. Maintain proper wheel bearingadjustment.

Wheel Alignment and TireBalanceMaintaining front axle alignment isvery important to achievingmaximum tire life and vehiclecontrol. Inspecting steer axle tires inthe first 5 000 km (3,000 mi) –16 000 km (10,000 mi) of servicemiles will generally show if tires arewearing normally.

. Rapid outside shoulder wear onboth tires indicates too muchtoe-in.

. Rapid inside shoulder wear onboth tires indicates too muchtoe-out.

. Excessive wear on the inside oroutside of one steer tire, but notthe other, can indicate a toe-in ortoe-out condition coupled with amisaligned front or rear axle.

. Pulling to the right or left canindicate misalignment of thefront or rear axle, unequal tirepressures, or a damaged /mismatched tire.

trails around the nuts. Ensure thatno cracks or damage are present atwheel mount holes.

Check for leaks on outboard orinboard sides of wheel. Verify thatthe oil level in the hub is correct.

Wheel and Tire Balancing

Out-of-round or out-of-balancewheels or tires can cause vehiclevibration, bounce, and shimmy.Replace damaged or out-of-roundwheels. Out-of-round tires andwheel assemblies can sometimesbe corrected by rechecking the tirerelative to the wheel. The tire andwheel assembly should thereafterbe dynamically balanced andreinspected while spinning for anout of round condition.

Hub-Piloted Wheel InstallationProcedure

{ Warning

To prevent property damage,personal injury, and/or death, useonly the same type and stylewheels and mounting hardware toreplace original parts. Failure todo so may result in an assemblythat looks fine but does not fittogether properly. This couldcause wheel or fastener failures.

Out-of-round tires and wheelassemblies can sometimes becorrected by re-clocking the tirerelative to the wheel.

Tightening procedure for discwheels with flange nuts(hub-piloted):

1. Clean the mating surfaces ofthe hub, drum, and wheel(s) aswell as the wheel studs andwheel nuts with a wire brushprior to assembly.

2. Lubricate the two-piece wheelnuts by putting two drops of oilin the slot between the nut andwasher and spin the washer tospread the oil around thenut-to-washer contact surface.

3. Carefully lubricate the wheelstud threads by wiping themwith a freshly oiled cloth. Donot get the oil on any othersurfaces or the wheel clampingeffectiveness will be reduced.

4. To prevent aluminum wheelsfrom getting stuck on the hubdue to corrosion, apply a thincoat of anti-seize compound ordisc brake corrosion controlgrease to the hub pilotpads only.

5. Slide the inner and outerwheels (if duals) or the steerwheel over the wheel studsand onto the pilot pads of thehub. Care must be taken toavoid damage to the studthreads while positioning thewheel. Ensure that the wheel isresting on the pilot pads and isagainst the brake drum.

6. Hand-start all wheel nuts toprevent cross-threading.

7. Starting with the nut at 12o’clock position and using theappropriate star or crisscrosspattern, run the wheel nutsdown the wheel studs with animpact wrench until they aresnug against the wheel. Thepurpose of this step is to snugthe wheel(s) in the correctposition, not to apply the finaltorque. The tightening of eachnut should be stoppedimmediately when the wheel iscontacted, and result in awheel nut torque well below thefinal specified torque.

8. Use a calibrated torque wrenchto apply the specified torque toeach wheel nut in thesequence specified in thewheel nut torque sequencediagram above. See Capacitiesand Specifications 0 408.

9. All wheels undergo a processcalled joint settling whenplaced in service after a wheelinstallation has beenperformed. This process resultsin a reduction in the torque onthe wheel nuts. To correct thiscondition, operate the vehiclenormally for approximately80 km (50 mi), then use acalibrated torque wrench tore-torque the wheel nuts tospecification using theappropriate pattern shown inthe wheel nut torque sequencediagram.

10. As part of a daily pretripinspection, look for loose ormissing wheel nuts. Also, lookfor rust streaks extendingoutward from the wheel nuts.This can be an indicator that

one or more wheel nuts areloose, even if they cannot beturned by hand. Normalperiodic maintenance shouldalso include checking thewheel nut torque with a torquewrench.

Wheel Nut Torque Maintenance

Tighten and maintain the wheel andrim mounting nuts to the propertorque. Loose nuts or overtightenednuts can lead to premature wearand possible failure of the wheel,rim, and/or mounting hardware.

Used Replacement Wheels

{ Warning

Replacing a wheel with a usedone is dangerous. How it hasbeen used or how far it has beendriven may be unknown. It couldfail suddenly and cause a crash.When replacing wheels, use anew GM original equipmentwheel.

386 Service and Maintenance

Front Axle

Inspection and Lubrication (4x2Models)

Check to make sure that the frontaxle mounting U-bolts, attaching ormounting bolts, and nuts aresecurely tightened. Loose ormisaligned front axles will affectvehicle alignment, front tire wear,and handling.

Re-torque the U-bolt nuts after thefirst 1 600 km (1,000 mi) and every58 000 km (36,000 mi) thereafter.

Observe the following whenchecking the front axle fordamaged, binding, or worn parts,and adequate lubrication:

. Kingpin wear inspection requiresthat no weight is on the tires.

. Kingpin and kingpin bushinglubrication requires that thevehicle weight is off the tires andthe front wheels are turned fullyto the left or right prior toinstalling grease distribution.

. Kingpin thrust bushinglubrication requires that thevehicle weight is resting on thetires.

. Power grease guns may beused; however, a hand-pumpedgrease gun is recommended foroptimal grease distribution withineach component joint.

. Inspect, lubricate, and adjust thewheel bearings at regularintervals.See Additional Maintenance andCare (Lubrication) 0 379 orAdditional Maintenance andCare (Maintenance Instructions)0 383 and MaintenanceSchedule 0 361.

Inspection and Lubrication (4x4Models)

Proper lubrication and inspectionsof the front drive components mustbe followed. Both the front driveaxle and the transfer case oil levelmust be checked periodically, andalso inspected for possible oil loss.

The proper lubrication level is to thebottom of the oil fill hole with thevehicle on level ground.

Observe the front axle for damaged,binding, or worn parts, andadequate lubrication.

Make sure the axle mounting U-boltnuts, attaching or mounting boltsand nuts, are securely tightened.Loose or misaligned rear axles willaffect vehicle alignment, front tirewear, and handling.

Re-torque the U-bolt nuts asneeded. See Capacities andSpecifications 0 408.

Normal Maintenance

During operation, the air and oilinside the hub/wheel cavityexpands. It is normal for a mist of oilto be present on the outside of thehubcap around the vent slit or hole.Over time, if not wiped off, this filmmay collect dust and appearunsightly. If the entire face and endof the hubcap become wet with oil,investigate the cause. Refer to theservice manual for repairprocedures.

Service and Maintenance 387

Routinely clean the hubcap toensure that the lubricant level canbe easily observed through the clearwindow as intended.

In situations where the window isclean on the outside, but discoloredon the inside, check the lubricantlevel by removing the rubber fill/ventplug and insert a finger intothe hole.

The specified lubricant level for GMclear window type hubcaps is fromthe minimum line to 0.8 cm (5/16 in)above the minimum line.

If the lubricant level suddenly dropsdramatically below the minimumlevel, see the service manual fordiagnostic procedure.

Alignment

Maintaining front axle alignment isvery important to achievingmaximum tire life and vehiclecontrol. Inspecting steer axle tires inthe first 5 000 km(3,000 mi)-16 000 km (10,000 mi) ofservice will generally show if tiresare wearing normally.

. Rapid outside shoulder wear onboth tires indicates too muchtoe-in.

. Rapid inside shoulder wear onboth tires indicates too muchtoe-out.

. Excessive wear on the inside oroutside of one steer tire, but notthe other, can indicate a toe-in ortoe-out condition coupled with amisaligned front or rear axle.

. Pulling to the right or left canindicate misalignment of thefront or rear axle, unequal tirepressures, or a damaged/mismatched tire.

See Tires 0 331 for additionalrelated information.

{ Warning

All new GM vehicles usenon-asbestos brake linings.However, exposure to excessiveamounts of brake material dustmay be a potentially serioushealth hazard. To help protectyourself and others, follow all ofthe precautions in this Sectionwhen servicing the brakes.

Follow these precautions:

. Always wear a respiratorapproved by National Institutefor Occupational Safety andHealth (NIOSH) or Mine SafetyAppliances (MSA) during allbrake service procedures. Wearthe respirator from removal ofthe wheels through assembly.

. Never use compressed air or drybrushing to clean brake parts orassemblies.

. Clean brake parts andassemblies in the open air.During disassembly, carefully

place all parts on the floor toprevent getting dust into the air.Use an industrial vacuumcleaner with a HEPA filtersystem to clean dust from thebrake drums, backing plates,and other brake parts. Afterusing the vacuum, remove anyremaining dust with a ragsoaked in water and wrung untilnearly dry.

. Never use compressed air or drysweeping to clean the workarea. Use an industrial vacuumcleaner with a HEPA filtersystem and rags soaked inwater and wrung until nearly dry.Dispose of used rags with careto prevent getting dust into theair. Use an approved respiratorwhen emptying vacuum cleanersand handling used rags.

. Wash your hands before eating,drinking, or smoking. Vacuumyour work clothes after use, andthen launder them separately,without shaking them, to preventfiber dust from getting intothe air.

Hydraulic Brakes

Brake Inspection and Adjustment

This inspection or adjustmentshould only be performed byqualified service personnel andmust be in accordance withinstructions provided in the servicemanual.

Establish a regular schedule forperiodic cleaning, lubrication, andinspection, based on the type ofvehicle operation. It is difficult topredetermine an exact maintenanceinterval (time or mileage) sincevehicles are used in a variety ofapplications and conditions.See Maintenance Schedule 0 361and Owner Checks and Services(Inspection Guide) 0 368.

On a periodic basis of at least onceper year, inspect the entire brakesystem for:

. The proper operation of theservice and parking brakes.

. The condition of the discs,calipers, and ABS exciter teeth.

. Hydraulic fluid leaks.

Service and Maintenance 389. Hose or pipe damage.

. The condition of the ABS wheelspeed sensors and wiring.

. Proper ABS wheel speedsensor-to-exciter teeth gap.

Inspect brake lining at everymaintenance interval. During severeservice operations or prolongedperiods of stop-and-go operation,the brakes may require morefrequent inspection. Establishinspection intervals that provide forlining replacement before damageto the disc occurs. Excessive liningwear may allow the metal brakeshoe to damage the brake disc.

Brake Lines, Hoses, and Fittings

. Check lines for kinks, dents,corrosion, or ruptures.

. Check hoses for abrasion, kinks,soft spots, ruptures, collapse,cracks, twists, or loose framesupports. When replacing ahose, be sure there is enoughclearance to prevent the newhose from rubbing against othercomponents.

. Examine all connections forleaks.

. Repair or replace brake linetubes, hoses, or fittings asrequired.

Fluid Precautions

The brake system consists of twocompletely separate hydraulicsystems operating with two differentand incompatible fluids: powersteering fluid and hydraulic brakefluid.

{ Warning

The wrong or contaminated brakefluid could result in damage to thebrake system. This could result inthe loss of braking leading toinjury, death, or property damage.Always use the proper GMapproved brake fluid.

Caution

If brake fluid is spilled on thevehicle's painted surfaces, thepaint finish can be damaged.Immediately wash off any paintedsurface.

The following should always beobserved to avoid fluidcontamination. Use only properlyidentified and specified (orequivalent) fluids, and add fluidsonly to the following locations:

. Brake fluid to the brake mastercylinder.

. Power steering fluid to the powersteering fluid pump reservoir.

Brake Fluid Level

During normal vehicle operation andservicing, the fluid level will varybetween the bottom of the ring (full)and 2.5 cm (1 in) in the mastercylinder mounted front reservoir. Donot fill the master cylinder to the topof the reservoir. Overfilling may leadto overflow. A MIN and MAX

Check and refill the brake fluidreservoir:

1. Clean the reservoir caps beforeremoval to prevent dirt or waterfrom entering the reservoir.

2. Visually inspect the fluid level.

3. If necessary, add brake fluidfrom a clean unopenedcontainer.

4. Use only DOT 3 brake fluidcertified to meet manufacturerspecifications.

5. Fill the brake fluid reservoir tothe MAX line, but do notexceed the MAX fillspecifications.

If brake fluid must be addedfrequently to maintain the properlevel in the master cylinder, there iseither rapid pad wear or a fluidsystem leak. A more frequent andthorough brake inspection isrequired.

Electrical

Batteries

Battery life and performance variesgreatly depending on duty cycle.Conditions such as short runsbetween starts, low ambientoperating temperatures, use ofbattery current without the enginerunning, and vibration will reducebattery life. Battery life is alsoaffected by the condition ofinterrelated components, such asalternators, battery cables,connections, engine startability, andstarter. To maximize battery life, it isimportant to keep electricalcomponents, battery boxes, and the

engine in top condition and tominimize or eliminate electricalloads when the engine is notrunning.

Battery life can be extended bykeeping the batteries fully chargedat all times. Periodically chargingthe batteries with a battery chargermay be able to charge the batteriesmore completely than the vehicle’salternator in certain severeapplications. Use a battery charger(float charger) that automaticallyreduces amperage or shuts offwhen the batteries are fully charged.Use of a Midtronics 55-Amp PowerSupply/Smart (Battery) Charger,Model Number PCX550,Part Number PSC550CCKIT (orequivalent), available through yourGM dealer, is recommended.

Cold batteries resist charging.Battery performance can beimproved by regularly or evenperiodically storing vehicles andcharging batteries with an automaticfloat charger for 8 to 24 hours in awarm garage during the cold wintermonths.

Service and Maintenance 391

Caution

To prevent property damage, donot allow batteries to becomeheavily discharged and exposedto subfreezing weather that willcause them to freeze and becomedamaged.

Your vehicle utilizesmaintenance-free batteries, whichwill not require the periodic additionof water. Wipe the tops of thebatteries clean to prevent a slowcurrent flow through the dirt,resulting in a loss of charge. Besure the terminals are clampedtightly and that the battery isclamped securely in the battery box.

For best results:

. Do not mix and match batterymodels/manufacturers in thesame battery pack.

. Do not use batteries withdiffering CCA ratings in thesame battery pack.

. Do not use batteries with morethan one year difference in theinstalled age of batteries in thesame battery pack.

Battery Cables

Caution

To prevent property damage,when working around theterminals and battery, use extracare to prevent shorting. A goodpractice is to insulate pliers andscrewdrivers. Do not checkbattery condition by shorting(flashing) across terminals.

Battery cable terminals must beclean and tight. Use a mixture of hotwater and common baking soda forremoving terminal corrosion and forcleaning the top of the battery.Brighten the contact surfaces withsteel wool, apply a light coat ofdielectric grease, and reassemble.Be sure the terminals are clampedtightly. See your dealer for greasespecifications.

Electrical Charging and StartingSystem Test

At every Preventive Maintenance(PM), fully charge the batteriesusing an automatic float charger.Then, have a qualified technicianperform an electrical system test,available through your dealer, tocatch electrical system problemsbefore they cause further damage tothe batteries and prevent a strandedvehicle. The test will check foralternator amperage output, startercurrent draw, and battery amperagecapacity. This type of testing willdetect weaknesses that may not yetbe apparent during normal dailyoperations.

TerminalInspection-Cleaning-CorrosionProtection

Periodically inspect electricalconnectors on the engine, battery,and frame for corrosion andtightness. Inspect exposed cablesfor fraying or signs of abrasion.Exposed terminals, such ascranking motor, alternator, andfeed-through studs should be

control operations; it also canreduce engine life and/or jeopardizethe warranty.

Receipts covering the performanceof regular maintenance should beretained in the event questions ariseconcerning maintenance. Thereceipts should be transferred toeach subsequent owner of theengine (vehicle).

For information regarding routinescheduled maintenance such asreplacement of oil, filters, coolant,belts, belt tensioners, etc., andinspection and adjustment of items,such as valve lash, etc., refer to theEngine Operation and MaintenanceManual supplied with the vehicle.

Engine Fluids andContaminated Material

Engine fluids (oil, fuel, and coolant)may be a hazard to human healthand the environment. Handle allfluids and other contaminatedmaterials (such as filters, rags) inaccordance with applicableregulations. Recycle or dispose of

engine fluids, filters, and othercontaminated materials according toapplicable regulations.

Fuel System

Frequently inspect the condition ofthe fuel tanks and mountinghardware, fuel tank cap and vent,fuel lines, clips, and routing. Atevery Preventive Maintenance (PM),or daily if necessary, drain waterand sediment from the fuel/waterseparator filter. Be sure to use theproper fuel/water separator filterelement with the correct partnumber and filter efficiency rating.

Fuel Tank Draining and Cleaning

Periodically (annually isrecommended) drain water andsediment from the fuel tank. Drainand flush sediment from the fueltank at least every 12 months ormore frequently if fuel quality or typeof fuel dictates.

Since Ultra-Low Sulfur Diesel(ULSD) fuel tends to absorb morewater and engines are operating athigher temperatures, microbe

growth in the fuel tanks has becomemore prevalent. Microbe growthresults in more contaminants in thefuel and reduces fuel filter life. Sincefuel tank draining does not removeall microbes, fuel tank drainingalone will not eliminate the problem.If microbe growth is found inthe fuel:

1. Drain and clean the fuel tank(s)every 12 months or more often.Clean the tanks with aprofessional fuel tank cleaningsystem (available through yourdealer) or have your dealerperform the service for you.

2. Treat the vehicle fuel tanks andbulk tanks regularly with abiocide from a reputablevendor.

3. Purchase fuel only fromvendors that pretreat their fuelwith biocides.

4. Periodically test the fuelsupplied by your fuel vendor forthe presence of microbes.

*Cooling system refill capacities vary considerably due to differences in engine models and optional equipment, inaddition to the amount of coolant remaining in the system after draining. Total capacity is approximately30 L (8 gal).If the system has been flushed with water or cleaner, a significant amount of the rinse water will remain in thesystem. In this case, refilling with a mixture with a higher percentage (60–66%) of coolant concentrate is advised inorder to achieve a final mixture closer to 50/50. Fill the system and run the vehicle until the thermostat opens.Before adding any fluid, check the coolant concentration and add additional water or concentrated undilutedcoolant to adjust the concentration. Run the vehicle and retest for coolant volume level (set to MAX line) andconcentration level.

**Do not overfill the DEF tank. See Diesel Exhaust Fluid 0 220.

A variety of transmissions are available for your vehicle. Refer to the Allison Automatic Transmission Manual forthe most up-to-date specific service instructions, required capacities, and transmission fluids.

All quantities are approximate. When adding, be sure to fill to the appropriate level, as recommended in thismanual. Recheck fluid level after filling.

Collision Damage RepairIf the vehicle is involved in acollision and it is damaged, have thedamage repaired by a qualifiedtechnician using the properequipment and quality replacementparts. Poorly performed collisionrepairs diminish the vehicle resalevalue, and safety performance canbe compromised in subsequentcollisions.

Collision Parts

Genuine GM Collision parts are newparts made with the same materialsand construction methods as theparts with which the vehicle wasoriginally built. Genuine GMCollision parts are the best choice toensure that the vehicle's designed

Chevrolet Silverado 4500HD/5500HD/6500HD Owner Manual (GMNA-Localizing-U.S.-12102101) - 2019 - crc - 10/2/18

422 Customer Information

appearance, durability, and safetyare preserved. The use of GenuineGM parts can help maintain the GMNew Vehicle Limited Warranty.

Recycled original equipment partsmay also be used for repair. Theseparts are typically removed fromvehicles that were total losses inprior crashes. In most cases, theparts being recycled are fromundamaged sections of the vehicle.A recycled original equipment GMpart may be an acceptable choice tomaintain the vehicle's originallydesigned appearance and safetyperformance; however, the history ofthese parts is not known. Such partsare not covered by the GM NewVehicle Limited Warranty, and anyrelated failures are not covered bythat warranty.

Aftermarket collision parts are alsoavailable. These are made bycompanies other than GM and maynot have been tested for the vehicle.As a result, these parts may fitpoorly, exhibit premature durability/corrosion problems, and may notperform properly in subsequent

collisions. Aftermarket parts are notcovered by the GM New VehicleLimited Warranty, and any vehiclefailure related to such parts is notcovered by that warranty.

Repair Facility

GM also recommends that youchoose a collision repair facility thatmeets your needs before you everneed collision repairs. Your dealermay have a collision repair centerwith GM-trained technicians andstate-of-the-art equipment, or beable to recommend a collision repaircenter that has GM-trainedtechnicians and comparableequipment.

Insuring the Vehicle

Protect your investment in the GMvehicle with comprehensive andcollision insurance coverage. Thereare significant differences in thequality of coverage afforded byvarious insurance policy terms.Many insurance policies providereduced protection to the GMvehicle by limiting compensation fordamage repairs through the use of

aftermarket collision parts. Someinsurance companies will notspecify aftermarket collision parts.When purchasing insurance, werecommend that you ensure that thevehicle will be repaired with GMoriginal equipment collision parts.If such insurance coverage is notavailable from your currentinsurance carrier, consider switchingto another insurance carrier.

If the vehicle is leased, the leasingcompany may require you to haveinsurance that ensures repairs withGenuine GM Original EquipmentManufacturer (OEM) parts orGenuine Manufacturer replacementparts. Read the lease carefully, asyou may be charged at the end ofthe lease for poor quality repairs.

If a Crash Occurs

If there has been an injury, callemergency services for help. Do notleave the scene of a crash until allmatters have been taken care of.Move the vehicle only if its position

. General description of thedamage to the other vehicle

Choose a reputable repair facilitythat uses quality replacement parts.See “Collision Parts” earlier in thissection.

If the airbag has inflated, see WhatWill You See after an AirbagInflates? 0 64.

Managing the Vehicle DamageRepair Process

In the event that the vehicle requiresdamage repairs, GM recommendsthat you take an active role in itsrepair. If you have a pre-determinedrepair facility of choice, take thevehicle there, or have it towed there.Specify to the facility that anyrequired replacement collision partsbe original equipment parts, eithernew Genuine GM parts or recycledoriginal GM parts. Remember,recycled parts will not be covered bythe GM vehicle warranty.

Insurance pays the bill for the repair,but you must live with the repair.Depending on your policy limits,your insurance company mayinitially value the repair usingaftermarket parts. Discuss this with

the repair professional, and insist onGenuine GM parts. Remember,if the vehicle is leased, you may beobligated to have the vehiclerepaired with Genuine GM parts,even if your insurance coveragedoes not pay the full cost.

If another party's insurancecompany is paying for the repairs,you are not obligated to accept arepair valuation based on thatinsurance company's collision policyrepair limits, as you have nocontractual limits with that company.In such cases, you can have controlof the repair and parts choices aslong as the cost stays withinreasonable limits.

Vehicle DataRecording andPrivacyThe vehicle has a number ofcomputers that record informationabout the vehicle’s performance andhow it is driven. For example, thevehicle uses computer modules tomonitor and control engine andtransmission performance, tomonitor the conditions for airbagdeployment and deploy them in acrash, and, if equipped, to provideantilock braking to help the drivercontrol the vehicle. These modulesmay store data to help the dealertechnician service the vehicle.Some modules may also store dataabout how the vehicle is operated,such as rate of fuel consumption oraverage speed. These modules mayretain personal preferences, such asradio presets, seat positions, andtemperature settings.

Event Data RecordersThis vehicle is equipped with anevent data recorder (EDR). Themain purpose of an EDR is torecord, in certain crash or nearcrash-like situations, such as an airbag deployment or hitting a roadobstacle, data that will assist inunderstanding how a vehicle’ssystems performed. The EDR isdesigned to record data related tovehicle dynamics and safetysystems for a short period of time,typically 30 seconds or less. TheEDR in this vehicle is designed torecord such data as:

. How various systems in yourvehicle were operating;

. Whether or not the driver andpassenger safety belts werebuckled/fastened;

. How far (if at all) the driver wasdepressing the accelerator and/or brake pedal; and,

. How fast the vehicle wastraveling.

Customer Information 427

These data can help provide abetter understanding of thecircumstances in which crashes andinjuries occur.

NoteEDR data are recorded by yourvehicle only if a non-trivial crashsituation occurs; no data arerecorded by the EDR under normaldriving conditions and no personaldata (e.g., name, gender, age, andcrash location) are recorded.However, other parties, such as lawenforcement, could combine theEDR data with the type ofpersonally identifying data routinelyacquired during a crashinvestigation.

To read data recorded by an EDR,special equipment is required, andaccess to the vehicle or the EDR isneeded. In addition to the vehiclemanufacturer, other parties, such aslaw enforcement, that have thespecial equipment, can read theinformation if they have access tothe vehicle or the EDR.

GM will not access these data orshare it with others except: with theconsent of the vehicle owner or,if the vehicle is leased, with theconsent of the lessee; in responseto an official request by police orsimilar government office; as part ofGM's defense of litigation throughthe discovery process; or, asrequired by law. Data that GMcollects or receives may also beused for GM research needs or maybe made available to others forresearch purposes, where a need isshown and the data is not tied to aspecific vehicle or vehicle owner.

OnStarIf the vehicle is equipped withOnStar and has an active serviceplan, additional data may becollected through the OnStarsystem. This includes informationabout the vehicle’s operation;collisions involving the vehicle; theuse of the vehicle and its features;and, in certain situations, thelocation and approximate GPSspeed of the vehicle.
