GM's exclusive TPC Spec system considers over adozen critical specifications that impact the overallperformance of your vehicle, including brake systemperformance, ride and handling, traction control, and tirepressure monitoring performance. GM's TPC Specnumber is molded onto the tire's sidewall near the tiresize. If the tires have an all!season tread design, theTPC spec number will be followed by an MS for mudand snow. SeeTire Sidewall Labelingon page 7!60foradditional information.
GM recommends replacing tires in sets of four. This isbecause uniform tread depth on all tires will help keepyour vehicle performing most like it did when the tireswere new. Replacing less than a full set of tires canaffect the braking and handling performance of yourvehicle. SeeTire Inspection and Rotationon page 7!71for information on proper tire rotation.
{WARNING:
Mixing tires could cause you to lose control while
driving. If you mix tires of different sizes, brands,
or types (radial and bias-belted tires), the vehicle
might not handle properly, and you could have a
crash. Using tires of different sizes, brands,
or types could also cause damage to your vehicle.
Be sure to use the same size, brand, and type
tires on all wheels.
Your vehicle may have a different size spare than
the road tires (those originally installed on your
vehicle). When new, your vehicle included a spare
tire and wheel assembly with a similar overall
diameter as your vehicle's road tires and wheels,
so it is all right to drive on it. Because this spare
was developed for use on your vehicle, it will not
affect vehicle handling.

{WARNING:
If you use bias-ply tires on the vehicle, the
wheel rim flanges could develop cracks after
many miles of driving. A tire and/or wheel
could fail suddenly, causing a crash. Use
only radial-ply tires with the wheels on the
vehicle.
If you must replace your vehicle's tires with those thatdo not have a TPC Spec number, make sure they arethe same size, load range, speed rating, andconstruction type (radial and bias!belted tires) as yourvehicle's original tires.
Vehicles that have a tire pressure monitoring systemmay give an inaccurate low!pressure warning ifnon!TPC spec rated tires are installed on your vehicle.Non!TPC Spec rated tires may give a low!pressurewarning that is higher or lower than the proper warninglevel you would get with TPC Spec rated tires. SeeTirePressure Monitor System on page 7!67.
Your vehicle's original equipment tires are listed on theTire and Loading Information Label. SeeLoading theVehicleon page 6!32, for more information about theTire and Loading Information Label and its location onyour vehicle.
Different Size Tires and Wheels
If you add wheels or tires that are a different size thanyour original equipment wheels and tires, this couldaffect the way your vehicle performs, including itsbraking, ride and handling characteristics, stability, andresistance to rollover. Additionally, if your vehicle haselectronic systems such as anti!lock brakes, rolloverairbags, traction control, and electronic stability control,the performance of these systems can be affected.
{WARNING:
If you add different sized wheels, your vehicle
may not provide an acceptable level of
performance and safety if tires not recommended
for those wheels are selected. You may increase
the chance that you will crash and suffer serious
injury. Only use GM specific wheel and tire
systems developed for your vehicle, and have
them properly installed by a GM certified
technician.

Care of Safety Belts
Keep belts clean and dry.
{WARNING:
Do not bleach or dye safety belts. It may severely
weaken them. In a crash, they might not be able
to provide adequate protection. Clean safety belts
only with mild soap and lukewarm water.
Weatherstrips
Silicone grease on weatherstrips will make them lastlonger, seal better, and not stick or squeak. Applysilicone grease with a clean cloth. During very cold,damp weather frequent application may be required.SeeRecommended Fluids and Lubricantsonpage 8!10.
Washing Your Vehicle
The best way to preserve the vehicle's finish is to keepit clean by washing it often.
Notice:Certain cleaners contain chemicals that candamage the emblems or nameplates on the vehicle.Check the cleaning product label. If it states that itshould not be used on plastic parts, do not use it onthe vehicle or damage may occur and it would notbe covered by the warranty.
Do not wash the vehicle in direct sunlight. Use a carwashing soap. Do not use cleaning agents that arepetroleum based or that contain acid or abrasives, asthey can damage the paint, metal or plastic on thevehicle. Approved cleaning products can be obtainedfrom your dealer/retailer. Follow all manufacturers'directions regarding correct product usage, necessarysafety precautions and appropriate disposal of anyvehicle care product.
Rinse the vehicle well, before washing and after toremove all cleaning agents completely. If they areallowed to dry on the surface, they could stain.
Dry the finish with a soft, clean chamois or an all-cottontowel to avoid surface scratches and water spotting.

.Automatic transmission fluid and filter change(normal service). SeeAutomatic TransmissionFluid on page 7!24.
.Four!wheel drive only: Transfer case fluid change(normal service). Check vent hose at transfer casefor kinks and proper installation. Check to be surevent hose is unobstructed, clear, and free ofdebris. During any maintenance, if a power washeris used to clean mud and dirt from the underbody,care should be taken to not directly spray thetransfer case output seals. High pressure watercan overcome the seals and contaminate thetransfer case fluid. Contaminated fluid willdecrease the life of the transfer case and shouldbe replaced.

Event Data Recorders
This vehicle has an Event Data Recorder (EDR). Themain purpose of an EDR is to record, in certain crash ornear crash-like situations, such as an airbagdeployment or hitting a road obstacle, data that willassist in understanding how a vehicle's systemsperformed. The EDR is designed to record data relatedto vehicle dynamics and safety systems for a shortperiod of time, typically 30 seconds or less. The EDR inthis vehicle is designed to record such data as:
.How various systems in your vehicle wereoperating
.Whether or not the driver and passenger safetybelts were buckled/fastened
.How far, if at all, the driver was pressing theaccelerator and/or brake pedal
.How fast the vehicle was traveling
This data can help provide a better understanding of thecircumstances in which crashes and injuries occur.
Important:EDR data is recorded by your vehicle only ifa non-trivial crash situation occurs; no data is recordedby the EDR under normal driving conditions and nopersonal data (e.g., name, gender, age, and crashlocation) is recorded. However, other parties, such aslaw enforcement, could combine the EDR data with thetype of personally identifying data routinely acquiredduring a crash investigation.
To read data recorded by an EDR, special equipment isrequired, and access to the vehicle or the EDR isneeded. In addition to the vehicle manufacturer, otherparties, such as law enforcement, that have the specialequipment, can read the information if they have accessto the vehicle or the EDR.
GM will not access this data or share it with othersexcept: with the consent of the vehicle owner or, if thevehicle is leased, with the consent of the lessee; inresponse to an official request of police or similargovernment office; as part of GM's defense of litigationthrough the discovery process; or, as required by law.Data that GM collects or receives may also be used forGM research needs or may be made available to othersfor research purposes, where a need is shown and thedata is not tied to a specific vehicle or vehicle owner.
