Temperature–A, B, C
The temperature grades are A (the highest),
B, and C, representing the tire's resistance to the
generation of heat and its ability to dissipate heat
when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the
tire to degenerate and reduce tire life, and
excessive temperature can lead to sudden tire
failure. The grade C corresponds to a level of
performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety
Standard No. 109. Grades B and A represent
higher levels of performance on the laboratory test
wheel than the minimum required by law. It should
be noted that the temperature grade for this tire is
established for a tire that is properly inflated and
not overloaded. Excessive speed, underinflation,
or excessive loading, either separately or in
combination, can cause heat buildup and possible
tire failure.
Wheel Alignment and Tire Balance
The tires and wheels on your vehicle were aligned andbalanced carefully at the factory to give you the longesttire life and best overall performance. Adjustments towheel alignment and tire balancing will not benecessary on a regular basis. However, if you noticeunusual tire wear or your vehicle pulling to one side orthe other, the alignment might need to be checked.If you notice your vehicle vibrating when driving on asmooth road, the tires and wheels might need to berebalanced. See your dealer/retailer for properdiagnosis.
Wheel Replacement
Replace any wheel that is bent, cracked, or badlyrusted or corroded. If wheel nuts keep coming loose,the wheel, wheel bolts, and wheel nuts should bereplaced. If the wheel leaks air, replace it (except somealuminum wheels, which can sometimes be repaired).See your dealer/retailer if any of these conditions exist.
Your dealer/retailer will know the kind of wheelyou need.
Each new wheel should have the same load-carryingcapacity, diameter, width, offset, and be mounted thesame way as the one it replaces.
7-77

If you need to replace any of your wheels, wheel bolts,wheel nuts, or Tire Pressure Monitor System (TPMS)sensors, replace them only with new GM originalequipment parts. This way, you will be sure to havethe right wheel, wheel bolts, wheel nuts, and TPMSsensors for your vehicle.
{WARNING:
Using the wrong replacement wheels, wheel bolts,
or wheel nuts on your vehicle can be dangerous.
It could affect the braking and handling of your
vehicle, make your tires lose air and make you
lose control. You could have a collision in which
you or others could be injured. Always use the
correct wheel, wheel bolts, and wheel nuts for
replacement.
Notice:The wrong wheel can also cause problemswith bearing life, brake cooling, speedometer orodometer calibration, headlamp aim, bumper height,vehicle ground clearance, and tire or tire chainclearance to the body and chassis.
SeeChanging a Flat Tireon page 7!80for moreinformation.
Used Replacement Wheels
{WARNING:
Putting a used wheel on the vehicle is dangerous.
You cannot know how it has been used or how
far it has been driven. It could fail suddenly and
cause a crash. If you have to replace a wheel,
use a new GM original equipment wheel.
Tire Chains
{WARNING:
Do not use tire chains. There is not enough
clearance. Tire chains used on a vehicle without
the proper amount of clearance can cause
damage to the brakes, suspension, or other
vehicle parts. The area damaged by the tire
chains could cause you to lose control of the
vehicle and you or others may be injured in a
crash. Use another type of traction device only if
its manufacturer recommends it for use on the
(Continued)

WARNING: (Continued)
vehicle and tire size combination and road
conditions. Follow that manufacturer's
instructions. To help avoid damage to the vehicle,
drive slowly, re!adjust or remove the device if it is
contacting the vehicle, and do not spin the
wheels. If you do find traction devices that will fit,
install them on the rear tires.
If a Tire Goes Flat
It is unusual for a tire to blowout while you are driving,especially if you maintain your vehicle's tires properly.If air goes out of a tire, it is much more likely to leak outslowly. But if you should ever have a blowout, here area few tips about what to expect and what to do:
If a front tire fails, the flat tire creates a drag that pullsthe vehicle toward that side. Take your foot off theaccelerator pedal and grip the steering wheel firmly.Steer to maintain lane position, and then gently braketo a stop well out of the traffic lane.
A rear blowout, particularly on a curve, acts much like askid and may require the same correction you woulduse in a skid. In any rear blowout remove your foot fromthe accelerator pedal. Get the vehicle under control bysteering the way you want the vehicle to go. It may bevery bumpy and noisy, but you can still steer. Gentlybrake to a stop, well off the road if possible.
{WARNING:
Lifting a vehicle and getting under it to do
maintenance or repairs is dangerous without the
appropriate safety equipment and training. If a
jack is provided with the vehicle, it is designed
only for changing a flat tire. If it is used for
anything else, you or others could be badly
injured or killed if the vehicle slips off the jack.
If a jack is provided with the vehicle, only use
it for changing a flat tire.
If a tire goes flat, the next part shows how to use thejacking equipment to change a flat tire safely.

Spare Tire
Your vehicle, when new, had a fully-inflated spare tire.A spare tire may lose air over time, so check its inflationpressure regularly. SeeInflation - Tire Pressureonpage 7!65andLoading the Vehicleon page 6!32forinformation regarding proper tire inflation and loadingyour vehicle. For instruction on how to remove, install orstore a spare tire, seeRemoving the Flat Tire andInstalling the Spare Tireon page 7!86andStoring aFlat or Spare Tire and Tools on page 7!94.
After installing the spare tire on your vehicle, you shouldstop as soon as possible and make sure the spare iscorrectly inflated. The spare tire is made to perform wellat speeds up to 70 mph (112 km/h) at the recommendedinflation pressure, so you can finish your trip.
Have the damaged or flat road tire repaired or replacedas soon as you can and installed back onto yourvehicle. This way, a spare tire will be available in caseyou need it again. Do not mix tires and wheels ofdifferent sizes, because they will not fit. Keep yourspare tire and its wheel together.
Appearance Care
Interior Cleaning
The vehicle's interior will continue to look its best if it iscleaned often. Although not always visible, dust and dirtcan accumulate on the upholstery. Dirt can damagecarpet, fabric, leather, and plastic surfaces. Regularvacuuming is recommended to remove particles fromthe upholstery. It is important to keep the upholsteryfrom becoming and remaining heavily soiled. Soilsshould be removed as quickly as possible. Thevehicle's interior may experience extremes of heat thatcould cause stains to set rapidly.
Lighter colored interiors may require more frequentcleaning. Use care because newspapers and garmentsthat transfer color to home furnishings may also transfercolor to the vehicle's interior.
When cleaning the vehicle's interior, only use cleanersspecifically designed for the surfaces being cleaned.Permanent damage may result from using cleaners onsurfaces for which they were not intended. Use glasscleaner only on glass. Remove any accidentalover-spray from other surfaces immediately. To preventover-spray, apply cleaner directly to the cleaning cloth.
7-98

The surface of these wheels is similar to the paintedsurface of the vehicle. Do not use strong soaps,chemicals, abrasive polishes, abrasive cleaners,cleaners with acid, or abrasive cleaning brushes onthem because they could damage the surface. Do notuse chrome polish on aluminum wheels.
Notice:Using chrome polish on aluminum wheelscould damage the wheels. The repairs would not becovered by the vehicle warranty. Use chrome polishon chrome wheels only.
Use chrome polish only on chrome-plated wheels, butavoid any painted surface of the wheel, and buff offimmediately after application.
Notice:Driving the vehicle through an automaticcar wash that has silicone carbide tire cleaningbrushes, could damage the aluminum orchrome-plated wheels. The repairs would not becovered by the vehicle warranty. Never drive avehicle that has aluminum or chrome-plated wheelsthrough an automatic car wash that uses siliconecarbide tire cleaning brushes.
Tires
To clean the tires, use a stiff brush with tire cleaner.
Notice:Using petroleum-based tire dressingproducts on the vehicle may damage the paint finishand/or tires. When applying a tire dressing, alwayswipe off any overspray from all painted surfaces onthe vehicle.
Sheet Metal Damage
If the vehicle is damaged and requires sheet metalrepair or replacement, make sure the body repair shopapplies anti-corrosion material to parts repaired orreplaced to restore corrosion protection.
Original manufacturer replacement parts will provide thecorrosion protection while maintaining the vehiclewarranty.
