For additional information refer to the tire manufacturer’s booklet included with your vehicle’s Owner Manual.
5-50
{CAUTION:
Poorly maintained and improperly used tires are dangerous.
(cid:127) Overloading your tires can cause
overheating as a result of too much friction. You could have an air-out and a serious accident. See Loading Your Vehicle on page 4-30.
(cid:127) Underinflated tires pose the same danger as overloaded tires. The resulting accident could cause serious injury. Check all tires frequently to maintain the recommended pressure. Tire pressure should be checked when your tires are cold. See Inflation - Tire Pressure on page 5-56.
(cid:127) Overinflated tires are more likely to be cut, punctured, or broken by a sudden impact — such as when you hit a pothole. Keep tires at the recommended pressure.
(cid:127) Worn, old tires can cause accidents. If your
tread is badly worn, or if your tires have been damaged, replace them.
Tire Sidewall Labeling Useful information about a tire is molded into its sidewall. The examples below show a typical passenger vehicle tire and a compact spare tire sidewall.
Passenger (P-Metric) Tire Example
(A) Tire Size: The tire size is a combination of letters and numbers used to define a particular tire’s width, height, aspect ratio, construction type, and service description. See the “Tire Size” illustration later in this section for more detail.

5-55
A Tire and Loading Information label is attached to the vehicle’s center pillar (B-pillar), below the driver’s door latch. This label shows your vehicle’s original equipment tires and the correct inflation pressures for your tires when they are cold. The recommended cold tire inflation pressure, shown on the label, is the minimum amount of air pressure needed to support your vehicle’s maximum load carrying capacity. For additional information regarding how much weight your vehicle can carry, and an example of the tire and loading information label, see Loading Your Vehicle on page 4-30. How you load your vehicle affects vehicle handling and ride comfort, never load your vehicle with more weight than it was designed to carry. When to Check Check your tires once a month or more. Do not forget to check the compact spare tire, it should be at 60 psi (420 kPa). For additional information regarding the compact spare tire, see Compact Spare Tire on page 5-83.
Inflation - Tire Pressure Tires need the correct amount of air pressure to operate effectively. Notice: Do not let anyone tell you that under-inflation or over-inflation is all right. It is not. If your tires do not have enough air (under-inflation), you can get the following:
Too much flexing Too much heat Tire overloading
(cid:127) Premature or irregular wear (cid:127) Poor handling (cid:127) Reduced fuel economy If your tires have too much air (over-inflation), you can get the following: (cid:127) Unusual wear (cid:127) Poor handling (cid:127) Rough ride (cid:127) Needless damage from road hazards
5-56
(cid:127) (cid:127) (cid:127) Tire Inspection and Rotation Tires should be rotated every 5,000 to 8,000 miles (8 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See When It Is Time for New Tires on page 5-58 and Wheel Replacement on page 5-62 for more information. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See Scheduled Maintenance on page 6-4.
How to Check Use a good quality pocket-type gage to check tire pressure. You cannot tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they are under-inflated. Check the tire’s inflation pressure when the tires are cold. Cold means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Remove the valve cap from the tire valve stem. Press the tire gage firmly onto the valve to get a pressure measurement. If the cold tire inflation pressure matches the recommended pressure on the Tire and Loading Information label, no further adjustment is necessary. If the inflation pressure is low, add air until you reach the recommended amount. If you overfill the tire, release air by pushing on the metal stem in the center of the tire valve. Re-check the tire pressure with the tire gage. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture.
When rotating your tires, always use the correct rotation pattern shown here.
5-57
Do not include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire and Loading Information label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 5-99.
{CAUTION:
Rust or dirt on a wheel, or on the parts to which it is fastened, can make wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off. See Changing a Flat Tire on page 5-66.
5-58
When It Is Time for New Tires
One way to tell when it is time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.
You need a new tire if any of the following statements are true: (cid:127) You can see the indicators at three or more places
around the tire.
(cid:127) You can see cord or fabric showing through the
tire’s rubber. The tread or sidewall is cracked, cut, or snagged deep enough to show cord or fabric. The tire has a bump, bulge, or split. The tire has a puncture, cut or other damage that cannot be repaired well because of the size or location of the damage.
(cid:127) (cid:127) (cid:127) Buying New Tires GM has developed and matched specific tires for your vehicle. The original equipment tires installed on your vehicle, when it was new, were designed to meet General Motors Tire Performance Criteria Specification (TPC spec) system rating. If you need replacement tires, GM strongly recommends that you get tires with the same TPC Spec rating. This way, your vehicle will continue to have tires that are designed to give the same performance and vehicle safety, during normal use, as the original tires. GM’s exclusive TPC Spec system considers over a dozen critical specifications that impact the overall performance of your vehicle, including brake system performance, ride and handling, traction control, and tire pressure monitoring performance. GM’s TPC Spec number is molded onto the tire’s sidewall by the tire manufacturer. If the tires have an all-season tread design, the TPC spec number will be followed by an MS for mud and snow. See Tire Sidewall Labeling on page 5-51 for additional information.
{CAUTION:
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 may not handle properly, and you could have a crash. Using tires of different sizes, brands, or types may also cause damage to your vehicle. Be sure to use the correct size, brand, and type of tires on all wheels. It is all right to drive with your compact spare temporarily, as it was developed for use on your vehicle. See Compact Spare Tire on page 5-83.
5-59
{CAUTION:
If you use bias-ply tires on your 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 your vehicle.
If you must replace your vehicle’s tires with those that do not have a TPC Spec number, make sure they are the same size, load range, speed rating, and construction type (radial and bias-belted tires) as your vehicle’s original tires. Your vehicle’s original equipment tires are listed on the Tire and Loading Information Label. This label is attached to the vehicle’s center pillar (B-pillar). See Loading Your Vehicle on page 4-30, for more information about the Tire and Loading Information Label and its location on your vehicle.
5-60
Different Size Tires and Wheels If you add wheels or tires that are a different size than your original equipment wheels and tires, this may affect the way your vehicle performs, including its braking, ride and handling characteristics, stability and resistance to rollover. Additionally, if your vehicle has electronic systems such as, antilock brakes; traction control; and electronic stability control, the performance of these systems can be affected.
{CAUTION:
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.
See Buying New Tires on page 5-59 and Accessories and Modifications on page 5-3 for additional information.
Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.
Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1.5) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction – AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.
5-61
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. Warning: 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 and balanced carefully at the factory to give you the longest tire life and best overall performance. Adjustments to wheel alignment and tire balancing will not be necessary on a regular basis. However, if you notice unusual tire wear or your vehicle pulling to one side or the other, the alignment may need to be checked. If you notice your vehicle vibrating when driving on a smooth road, your tires and wheels may need to be rebalanced. See your dealer for proper diagnosis.
Wheel Replacement Replace any wheel that is bent, cracked or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.
5-62
If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.
Used Replacement Wheels
{CAUTION:
Putting a used wheel on your 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.
{CAUTION:
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 problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance, and tire or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-66 for more information.
5-63
Accessory Inflator Your vehicle may have an accessory inflator. With it, you can inflate things like air mattresses and basketballs, and you can also use it to bring your tires up to the proper pressure. The accessory inflator is located in the rear compartment on the driver’s side. To access the accessory inflator, do the following: 1. Open the liftgate. See Liftgate on page 2-22 for
more information.
2. Lift the lever to move the third row rear seatback
forward. See Third Row Seat on page 1-18 for more information.
3. Remove the cover by pulling the lever up.
This symbol is on the accessory inflator switch.
Tire Chains
{CAUTION:
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 your 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 your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it is contacting your vehicle, and do not spin your vehicle’s wheels. If you do find traction devices that will fit, install them on the front tires.
5-64
There may be an accessory inflator kit stored in the rear compartment on the passenger’s side. It includes a 20-foot (6 m) hose with an air pressure gage and nozzle adapters.
{CAUTION:
Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate any object only to its recommended pressure.
To use your accessory inflator system, do the following:
1. Turn the ignition to ACCESSORY or RUN. 2. Attach the appropriate nozzle adapter, if required, to the end of the hose that has the pressure gage. 3. Attach that end of the hose to the object you wish
to inflate.
4. Remove the protective cap covering the outlet. 5. Attach the other end of the hose to the outlet. 6. Press the accessory inflator switch. The light in the switch will come on to show the system is working.
If you run the accessory inflator longer than
If the accessory inflator system does not turn on or the light does not come on, the fuse may be blown or installed incorrectly. See Fuses and Circuit Breakers on page 5-94 or see your retailer for service. Your accessory inflator will automatically shut off after about 10 minutes. The light in the switch will blink. After about one minute you can use the system again. Press the switch and the indicator light will come on. Notice: 30 minutes at a time, you could damage the inflator. The repairs would not be covered by your warranty. Run the inflator for short periods of time only. After running the accessory inflator for 30 minutes, wait at least 10 minutes before restarting the accessory inflator. To turn off the inflator, do the following: 1. Press the switch and detach the hose, first from the
inflated object, then from the outlet.
2. Put the protective cap back on. 3. Place the inflator kit tools in the pouch, and store in
the rear compartment on the passenger’s side.
To put the cover back on, line up the tabs at the bottom of the cover and put it in place. Push down the tab to secure the cover.

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 out slowly. But if you should ever have a blowout, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you would use in a skid. In any rear blowout remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop, well off the road if possible.
{CAUTION:
Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle 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. Use the jack provided with your vehicle only for changing a flat tire.
If a tire goes flat, the next part shows how to use the jacking equipment to change a flat tire safely.
Changing a Flat Tire If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your vehicle’s hazard warning flashers. See Hazard Warning Flashers on page 3-6 for more information.
5-66
{CAUTION:
Changing a tire can be dangerous. The vehicle can slip off the jack and roll over or fall on you or other people. You and they could be badly injured or even killed. Find a level place to change your tire. To help prevent the vehicle from moving:
1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine and do not restart
while the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
To be even more certain the vehicle will not move, you should put blocks at the front and rear of the tire farthest away from the one being changed. That would be the tire, on the other side, at the opposite end of the vehicle.
When your vehicle has a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.
The following information will tell you next how to use the jack and change a tire.

It should be stowed inside the vehicle by the cable provided. See “Storing the Flat Tire on an All-Wheel-Drive Vehicle” under Storing a Flat or Spare Tire and Tools on page 5-79 for more information. If you have a front-wheel-drive vehicle, the hoist is used to store a full-size or a flat road tire under the vehicle. See “Storing the Flat Tire on an Front-Wheel-Drive Vehicle” under Storing a Flat or Spare Tire and Tools on page 5-79 for more information.
4. Remove the compact spare tire from the cable. If the compact spare tire will not lower, check under the vehicle to see if the tire is hanging loose and the cable end and spring under the wheel plate are missing. If so, the secondary latch system is engaged. See Secondary Latch System on page 5-77. To continue changing the flat tire, see Removing the Flat Tire and Installing the Spare Tire on page 5-71.
3. Tilt the retainer at the end of the cable to remove
the compact spare tire, so it can be pulled up through the wheel opening. If your vehicle is an AWD vehicle, after removing the compact spare tire, turn the wrench clockwise to raise the cable back up. On an AWD vehicle, you can not store a full-size tire under the vehicle.
5-70
Removing the Flat Tire and Installing the Spare Tire If the wheel has a center cap, use the handle of the folding wrench to pry it off. Then, with the other end of the folding wrench, loosen the nuts.
If your vehicle has the plastic bolt-on wheel covers, loosen the bolts completely using the folding wrench, and remove the wheel cover.
Once the center cap and/or wheel cover are removed, use the following steps to remove the flat tire and install the spare tire.
1. Loosen the wheel
nuts using the folding wrench, but do not remove them. Turn the handle counterclockwise about 180 degrees, then flip the handle back to the starting position. This avoids taking the wrench off the lug nut for each turn.
If your vehicle has wheel locks and you
Notice: use an impact wrench to remove the wheel nuts, you could damage the lock nut or wheel lock key. Do not use an impact wrench to remove the wheel nuts if your vehicle has wheel locks.
5-71
If you use a jack to raise the vehicle
Notice: without positioning it correctly, you could damage your vehicle. When raising your vehicle on a jack, avoid contact with the rear axle control arms. Notice: molding and attempt to raise the vehicle, you could break the molding and/or cause other damage to your vehicle. Always position the jack so that when the jack head is raised, it will fit firmly in the notch located inboard from the rocker molding.
If you position the jack under the rocker

vehicle’s frame, inboard of the rocker molding. Position the jack and raise the jack head until it fits firmly into the notch in the vehicle’s frame nearest the flat tire. Do not raise the vehicle yet.
5-72
3. Put the compact spare tire near you.
{CAUTION:
Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.
{CAUTION:
Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.
4. Attach the folding wrench (A) to the jack (B), and turn the wrench clockwise to raise the jack head approximately 3 inches (7.6 cm).
5-73
{CAUTION:
Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause an accident. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or a paper towel to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off.
5. Raise the vehicle by turning the folding wrench
clockwise in the jack. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit under the wheel well.
6. Remove all the wheel nuts and take off the flat tire.
5-74
7. Remove any rust or dirt
from the wheel bolts, mounting surfaces and spare wheel.
8. Install the compact
spare tire and put the wheel nuts back on with the rounded end of the nuts toward the wheel.
{CAUTION:
Never use oil or grease on studs or nuts. If you do, the nuts might come loose. Your wheel could fall off, causing a serious accident.
Tighten each nut by hand until the wheel is held against the hub.
5-75
{CAUTION:
Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come loose and even come off. This could lead to an accident. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See Capacities and Specifications on page 5-99 for wheel nut torque specification.
Improperly tightened wheel nuts can lead
Notice: to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See Capacities and Specifications on page 5-99 for the wheel nut torque specification.
9. Lower the vehicle by attaching the folding wheel
wrench to the jack and turning the wrench counterclockwise. Lower the jack completely.
5-76
10. Tighten the wheel nuts
firmly in a crisscross sequence, as shown.
Your vehicle uses the underbody tire hoist assembly to store either the compact spare or a flat road tire. See Storing a Flat or Spare Tire and Tools on page 5-79
for instructions on storing the spare or flat tire correctly.Notice: Wheel covers will not fit on your compact spare. If you try to put a wheel cover on the compact spare, you could damage the cover or the spare.
11. Do not try to put a wheel cover on the compact spare tire. It will not fit. Store the wheel cover securely in the rear of the vehicle until you have the flat tire repaired or replaced.
Secondary Latch System Your vehicle may have an underbody-mounted tire hoist assembly equipped with a secondary latch system. It is designed to stop a tire from suddenly falling off your vehicle if the cable holding the spare tire is damaged. For the secondary latch to work, the tire must be stowed with the valve stem pointing down.
{CAUTION:
Before beginning this procedure read all the instructions. Failure to read and follow the instructions could damage the hoist assembly and you and others could get hurt. Read and follow the instructions listed below.
{CAUTION:
Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from the spare.
5-77
To release the spare tire from the secondary latch, do the following:
4. Lower the jack by turning the folding wrench
counterclockwise. Keep lowering the jack until the compact spare tire is resting on the folding wrench.
1. Place the jack under the vehicle, ahead of the rear
bumper. Position the center lift point of the jack under the center of the compact spare tire.
2. Turn the folding wrench clockwise to raise the jack
until it lifts the secondary latch device under the wheel plate.
3. Keep raising the jack until the compact spare tire stops moving upward and is held firmly in place. This lets you know that the secondary latch has released.
5-78
5. Grasp the compact spare tire with both hands and
pull it out from under the vehicle.
6. Reach under the vehicle and remove the folding
wrench and jack.
Have the hoist assembly inspected as soon as you can. You will not be able to store a spare or flat tire using the hoist assembly until it has been repaired or replaced.
Storing a Flat or Spare Tire and Tools
{CAUTION:
Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.
Storing the Spare Tire
{CAUTION:
The underbody-mounted spare tire needs to be stored with the valve stem pointing down. If the spare tire is stored with the valve stem pointing upwards, its secondary latch won’t work properly and the spare tire could loosen and suddenly fall from your vehicle. If this happened when your vehicle was being driven, the tire might contact a person or another vehicle, causing injury and, of course, damage to itself as well. Be sure the underbody-mounted spare tire is stored with its valve stem pointing down.
To store the spare tire, do the following: 1. Lay the tire near the rear of the vehicle with the
valve stem down.
2. Remove the small center cap by tapping the back
of the cap with the extension of the shaft, if the vehicle has aluminum wheels.
5-79
3. Slide the cable retainer through the center of the
wheel and start to raise the tire. Make sure the retainer is fully seated across the underside of the wheel.
4. When the tire is almost in the stored position, turn
the tire so the valve is towards the rear of the vehicle. This will help when you check and maintain tire pressure in the spare.
5. Raise the tire fully against the underside of the
vehicle. Continue turning the folding wrench until you feel more than two clicks. This indicates that the compact spare tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.
5-80
6. Make sure the tire is stored securely. Push, pull (A),
and then try to turn (B) the tire. If the tire moves, use the folding wrench to tighten the cable.
Storing the Flat Tire on a Front-Wheel-Drive Vehicle The flat tire is stored the same as the spare tire for front-wheel-drive vehicles. Refer to “Storing the Spare Tire” listed previously.
Storing the Flat Tire on an All-Wheel-Drive Vehicle 1. Remove the tire storage bag and cable package
from the jack storage area.
2. Remove the small center cap by tapping the back
of the cap with the extension of the shaft, if the vehicle has aluminum wheels.
3. Put the flat tire in the tire storage bag and place it
in the rear storage area with the valve stem pointing toward the front of the vehicle.

Storing the Tools
6. Pull on the cable to make sure it is secure.
7. Make sure the metal
tube is centered at the striker. Push the tube towards the front of the vehicle.
8. Close the liftgate and make sure it is latched
properly.
5-82
A. Strap B. Bag and Tools
C. Jack
Put back all tools as they were stored in the jack storage compartment and put the compartment cover back on.
To put the cover back on, line up the tabs on the right of the cover with the slots in the cover opening. Push the cover in place and push down the tab so that it rests in the groove. This secures the cover in place. Store the center cap or the plastic bolt-on wheel covers until a full size tire is put back on the vehicle. When you replace the compact spare with a full-size tire, reinstall the bolt-on wheel covers or the center cap. Hand-tighten them over the wheel nuts, using the folding wrench.
Compact Spare Tire Although the compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on the vehicle, stop as soon as possible and make sure the spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (105 km/h) for distances up to 3,000 miles (5 000 km), so you can
finish your trip and have the full-size tire repaired or replaced at your convenience. Of course, it is best to replace the spare with a full-size tire as soon as possible. The spare tire will last longer and be in good shape in case it is needed again. Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Do not use the compact spare on other vehicles. And do not mix the compact spare tire or wheel with other wheels or tires. They will not fit. Keep the spare tire and its wheel together. Notice: Tire chains will not fit your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare.
5-83
Appearance Care
Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. Your vehicle’s interior may experience extremes of heat that could cause stains to set rapidly. Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior. When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth.
5-84
If you use abrasive cleaners when cleaning
Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in your vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning your vehicle’s interior, maintain adequate ventilation by opening your vehicle’s doors and windows. Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your GM dealer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your GM dealer to remove odors from your vehicle’s upholstery. Do not clean your vehicle using the following cleaners or techniques: (cid:127) Never use a knife or any other sharp object to
remove a soil from any interior surface.
(cid:127) Never use a stiff brush. It can cause damage to
your vehicle’s interior surfaces.
(cid:127) Never apply heavy pressure or rub aggressively
with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal.
(cid:127) Use only mild, neutral-pH soaps. Avoid laundry
detergents or dishwashing soaps with degreasers. Using too much soap will leave a residue that leaves streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide.
(cid:127) Do not heavily saturate your upholstery while
cleaning.
(cid:127) Damage to your vehicle’s interior may result from the use of many organic solvents such as naptha, alcohol, etc.
Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on floor carpet and carpeted floor mats. For soils, always try to remove them first with plain water or club soda. Before cleaning, gently remove as much of the soil as possible using one of the following techniques:
For liquids: gently blot the remaining soil with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed. For solid dry soils: remove as much as possible and then vacuum.
To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with water or
club soda.
2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled. 4. Continue to gently rub the soiled area until the
cleaning cloth remains clean.
5. If the soil is not completely removed, use a mild
soap solution and repeat the cleaning process that was used with plain water.
If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness first. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet.
5-85
(cid:127) (cid:127) Leather A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of your leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on your leather.
Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on your instrument panel. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.
Child Restraint Pad The built-in child restraint pad is attached to the seat frame with fastener strips. You can remove the pad and hand wash it with mild soap and water.
5-86
Care of Safety Belts and Built-in Child Restraint Harness Keep the safety belts and the built-in child restraint harness clean and dry.
{CAUTION:
Do not bleach or dye safety belts or the built-in child restraint harness. If you do, they may be severely weakened. In a crash, they might not be able to provide adequate protection. Clean the safety belts and the child restraint harness only with mild soap and lukewarm water.
Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 6-12.
Washing Your Vehicle The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-91. Do not use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter the vehicle.
Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 5-87.
5-87
Finish Care Occasional waxing or mild polishing of the vehicle by hand may be necessary to remove residue from the paint finish. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-91. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on your vehicle. The vehicle has a “basecoat/clearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage the vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter.
Exterior painted surfaces are subject to aging, weather, and chemical fallout that can take their toll over a period of years. To help keep the paint finish looking new, keep the vehicle in a garage or covered whenever possible.
Windshield, Backglass, and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.
5-88
If you use strong soaps, chemicals,
Aluminum Wheels Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only GM-approved cleaners on aluminum or chrome-plated wheels. Keep the wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. The surface of these wheels is similar to the painted surface of the vehicle. Do not use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because the surface could be damaged. Do not use chrome polish on aluminum wheels.
If you drive your vehicle through an
Notice: automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes. Do not take the vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.
Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle.
5-89
Sheet Metal Damage If the vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty.
Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your GM dealer. Larger areas of finish damage can be corrected in your GM dealer’s body and paint shop.
Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.
Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

Vehicle Identification
Vehicle Identification Number (VIN)
This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration.
Engine Identification The eighth character in the VIN is the engine code. This code will help you identify your vehicle’s engine, specifications, and replacement parts.
Service Parts Identification Label You will find this label on the inside of the glove box. It is very helpful if you ever need to order parts. On this label, you will find the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) Production options and special equipment Be sure that this label is not removed from the vehicle.
5-92
Electrical System
Add-On Electrical Equipment Notice: Don’t add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-88.
Headlamp Wiring The headlamp wiring is protected by four internal fuses in the underhood fuse block. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away.
Windshield Wiper Fuses The windshield wiper motor is protected by an internal fuse in the underhood fuse block. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, be sure to get it fixed. The rear washer pump is controlled by a relay located in the engine compartment, behind the windshield washer fluid reservoir. The rear wiper motor is protected by a fuse located in the instrument panel fuse block.
Power Windows and Other Power Options Circuit breakers in the instrument panel fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed.
5-93
Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers, and fusible thermal links. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage or use one of the spare fuses in the underhood fuse block. Just pick some feature of your vehicle that you can get along without – like the radio or cigarette lighter – and use its fuse, if it is the right amperage. Replace it as soon as you can. There are two fuse blocks in your vehicle, the instrument panel fuse block and the underhood fuse block.
Instrument Panel Fuse Block The instrument panel fuse block is located at the right end of the instrument panel, on the passenger’s side of the vehicle. Open the front passegner’s door, and remove the cover, to access the fuse block. Your vehicle may not have all of the fuses listed.
