Tires Your new vehicle comes with high-quality tires made by a leading tire manufacturer. If you ever have questions about your tire warranty and where to obtain service, see your GM Warranty booklet for details. For additional information refer to the tire manufacturer’s booklet included with your vehicle’s Owner’s Manual.
{CAUTION:
(cid:127) 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 4-29.
(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.
5-52
CAUTION:
(Continued)
CAUTION:
(Continued)
(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.
See Inflation - Tire Pressure on page 5-59 for inflation pressure adjustment for high speed driving.
If your vehicle has low-profile tires, they
Notice: are more susceptible to damage from road hazards or curb impact than standard profile tires. Tire and/or wheel assembly damage can occur when coming into contact with road hazards like, potholes, or sharp edged objects or when sliding into a curb. Your GM warranty does not cover this type of damage. Keep tires set to the correct inflation pressure and, when possible avoid contact with curbs, potholes and other road hazards.
Winter Tires If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. High performance tires, like the original equipment tires installed on your vehicle, are designed for very responsive driving on wet or dry pavement and may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads. If you choose to use winter tires: • Use tires of the same brand and tread type on all
four wheel positions.
• Use only radial ply tires of the same size as your
original equipment tires.
See your Pontiac dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires on page 5-64.

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 A Tire and Loading Information label is attached to your vehicle’s center pillar, below the driver’s door latch. This label lists your vehicle’s original equipment tires and their recommended cold tire inflation pressures. 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 more information regarding how much weight your vehicle can carry, see Loading Your Vehicle on page 4-29.
5-59
(cid:127) (cid:127) (cid:127) How you load your vehicle affects vehicle handling and ride comfort. When driving with less than the maximum load capacity allowed for your vehicle, you can set tire inflation pressure to the recommended amounts shown in the following chart. 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 your compact spare tire. It should be at 60 psi (420 kPa). For more information about your vehicle’s compact spare tire, see Compact Spare Tire on page 5-76. How to Check Use a good quality pocket-type gage to check tire pressure. You can’t tell if your tires are properly inflated simply by looking at them. Radial tires may look properly inflated even when they’re underinflated.
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. Recheck the tire pressure with the tire gage.
5-60
Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. High Speed Operation
{CAUTION:
Driving at high speeds, 100 mph (160 km/h) or higher, puts an additional strain on tires. Sustained high-speed driving causes excessive heat build up and can cause sudden tire failure. You could have a crash and you or others could be killed. Some high-speed rated tires require inflation pressure adjustment for high speed operation. When speed limits and road conditions are such that a vehicle can be driven at high speeds, make sure the tires are rated for high speed operation, in excellent condition, and set to the correct cold tire inflation pressure for the vehicle load.
Vehicles equipped with 245/45ZR17 95W size tires, do not require additional air pressure for high-speed operation. If your vehicle has 235/40ZR18 91W size tires, use the following chart to determine the cold tire inflation pressure when operating your vehicle under high-speed conditions.

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 5-63 and Wheel Replacement on page 5-66 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.
When rotating non-directional tires, always use the correct rotation pattern shown here.
5-62
If your vehicle has 235/40ZR18 tires, they must roll in a certain direction for the best overall performance. The direction is shown by an arrow on the tire sidewall. Because these tires are uni-directional, they should be rotated as shown here. These tires should only be moved from front to rear and rear to front on the same side of the vehicle. Don’t 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 5-90.
{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 5-68.
When It Is Time for New Tires
One way to tell when it’s 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: • You can see the indicators at three or more places
• You can see cord or fabric showing through the
around the tire.
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
can’t be repaired well because of the size or location of the damage.
5-63
Buying New Tires To find out what kind and size of tires you need, look at the Tire and Loading Information label. For more information about this label and where to find it, see Loading Your Vehicle on page 4-29. Make sure the replacements are the same size, load capacity, speed rating and construction type (bias, bias-belted or radial) as your original tires.
{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.
{CAUTION:
Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare temporarily, it was developed for use on your vehicle. See Compact Spare Tire on page 5-76.
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.)
5-64
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. 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.
5-65
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.
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.
{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 5-68 for more information.
5-66
Used Replacement Wheels
Tire Chains
{CAUTION:
{CAUTION:
Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.
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, re-adjust or remove the device if it is contacting your vehicle, and do not spin your wheels. If you do find traction devices that will fit, install them on the rear tires.
5-67
If a Tire Goes Flat It is unusual for a tire to blowout while you’re driving, especially if you maintain your 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 your 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 hazard warning flashers.
5-68
{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 an automatic transmission shift lever
in PARK (P), or shift a manual transmission to FIRST (1) or REVERSE (R).
3. Turn off the engine and do not restart while
the vehicle is raised.
4. Do not allow passengers to remain in the
vehicle.
Put the wheel 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 you have 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.

Removing the Flat Tire and Installing the Spare Tire To remove the wheel nut caps, do the following:
2. Use the wheel wrench to loosen all the wheel nuts.
Don’t remove them yet.
3. Fit the jack handle onto the jack by sliding the open
end of the handle over the nut end of the jack.
1. Remove each wheel nut cap with the wheel nut cap
tool provided. Insert the nut cap tool into the nut cavity, squeeze the tool to grasp the nut cap, and pull out to remove it. If the nut caps are hard to remove, use the tip of the wheel wrench to remove the nut caps.
4. Position the jack and
raise the jack head until it fits firmly into notches, A and B, in the vehicle’s frame closest to the tire being changed.
5-71
5. 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.
5-72
6. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit underneath the wheel well. The jack handle must be unfolded to a right angle before it is used.
7. Remove all of the wheel nuts. 8. Remove the flat tire.
10. Install the compact spare tire.
{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.
{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 you need to, to get all the rust or dirt off.
9. Remove any rust or dirt
from the wheel bolts, mounting surfaces, and spare tire.
11. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel. Tighten each nut by hand until the wheel is held against the hub.

13. Tighten the wheel nuts
firmly in a crisscross sequence, as shown.
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. Do not try to put a wheel cover on your compact spare tire. It will not fit. Store a wheel cover in the trunk until you have the flat tire repaired or replaced.
12. Lower the vehicle by turning the wheel wrench
counterclockwise. Lower the jack completely.
{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 5-90 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 5-90 for the wheel nut torque specification.
5-74
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.
Store the tools as shown. Place the flat tire in the compact spare tire well in the compartment in the trunk floor. Then place the compact spare tire cover over the flat tire. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire on page 5-76. See the storage instructions label to replace your compact spare into your trunk properly.
5-75
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.
5-76
Appearance Care Cleaning products can be hazardous. Some are toxic. Other cleaning products can burst into flames if a match is struck near them or if they get on a hot part of the vehicle. Some are dangerous if their fumes are inhaled in an enclosed space. When anything from a container is used to clean the vehicle, be sure to follow the manufacturer’s warnings and instructions. Always open the doors or windows of the vehicle when cleaning the inside. Never use these to clean the vehicle: • Gasoline • Benzene • Naphtha • Carbon Tetrachloride • Acetone • Paint Thinner • Turpentine • Lacquer Thinner • Nail Polish Remover
They can all be hazardous — some more than others — and they can all damage the vehicle, too. Do not use any of these products unless this manual says you can. In many uses, these will damage the vehicle: • Alcohol • Laundry Soap • Bleach • Reducing Agents
Fabric/Carpet Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic, and painted surfaces with a clean, damp cloth. GM-approved cleaning products can be obtained from your dealer. Here are some cleaning tips: • Always read the instructions on the cleaner label. • Clean up stains as soon as you can before they set. • Carefully scrape off any excess stain.
• Use a clean cloth or sponge, and change to a clean
area often. A soft brush may be used if stains are stubborn.
• To avoid forming a ring on the fabric after spot cleaning, clean the entire area immediately or it will set.
Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft, white cloth.
For solids: remove as much as possible and then vacuum or brush.
2. Apply club soda water to a clean, soft, white
cloth. Do not over-saturate; the cloth should not drip water.
3. Clean the entire area. Avoid getting the fabric
too wet.
4. Start cleaning from the seams into the stain to
avoid a ring effect.
5. Continue cleaning, using a clean area of the cloth
each time it becomes soiled.
6. When the stain is removed, blot the cleaned area
with another dry, clean, soft, white cloth.
5-77
Using Cleaner on Fabric 1. First, try the cleaner on an area of the fabric that is not easily seen to make sure the cleaner does not affect the color of the fabric.
2. For liquids: blot with a clean, soft, white cloth.
For solids: remove as much as possible and then vacuum or brush.
3. Spray a small amount of the cleaner onto a clean
soft, white, cloth. Do not apply spray directly to the fabric.
4. Start cleaning from the seams into the stain to
avoid a ring effect.
5. Continue cleaning, using a clean area of the cloth
each time it becomes soiled.
6. When the stain is removed, blot the cleaned area
with another dry, clean, soft, white cloth.
7. If the cleaner leaves a ring effect, follow up with the club soda water instructions given earlier in this section.
Special Fabric Cleaning Problems Stains caused by such things as catsup, black coffee, egg, fruit, fruit juice, milk, soft drinks, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry. Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the “Using Cleaner on
Fabric” instructions described earlier.
Vinyl Use warm water and a clean cloth. • Rub with a clean, damp cloth to remove dirt. This may have to be done more than once.
• Things like tar, asphalt, and shoe polish will stain if
they are not removed quickly. Use a clean cloth and vinyl cleaner. See your dealer for this product.
5-78
Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry. • For stubborn stains, use a leather cleaner. • Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish, or shoe polish on leather.
• Soiled or stained leather should be cleaned
immediately. If dirt is allowed to work into the finish, it can harm the leather.
Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.
Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish.
If you use abrasive cleaners when cleaning
Glass Surfaces Notice: glass surfaces on your vehicle, you could scratch the glass. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Glass should be cleaned often. Your GM dealer can provide an approved cleaner, or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See Vehicle Care/Appearance Materials on page 5-84.
Care of Safety Belts Keep belts clean and dry.
{CAUTION:
Do not bleach or dye safety belts. If you do, 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.
5-79
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 5-84. 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.
5-80
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 5-80.
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 5-84. 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 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 glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed 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.
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.
5-81
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.
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.
5-82
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 GM 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 your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts.
Service Parts Identification Label You will find this label on your spare tire cover. It is very helpful if you ever need to order parts. On this label, you will find the following: • VIN • Model designation • Paint information • Production options and special equipment Be sure that this label is not removed from the vehicle. 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 1-50.
5-85
Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by fuses, circuit breakers and thermal links in the wiring itself. This greatly reduces the chance of fires caused by electrical problems. Look at the metallic 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 correct size. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one. 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 size you need. Replace it as soon as you can. Before replacing a fuse, turn every vehicle electrical switch off. There are two fuse blocks in your vehicle: the instrument panel fuse block and the engine compartment fuse block.
5-86
Instrument Panel Fuse Block This fuse block is located under the driver’s side of the instrument panel. The fuses here protect each separate circuit including headlamps. There are spare fuses inside the fuse box. If you have electrical failure, check here first.

Maintenance Schedule
Introduction Important: Keep engine oil at the proper level and change as recommended.
Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet or your dealer for details.
Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow scheduled maintenance may not be covered by warranty.
6-2
Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance is important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, be sure to maintain your vehicle properly.
Using the Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your GM Goodwrench® dealer.
This schedule is for vehicles that: • carry passengers and cargo within recommended
limits. You will find these limits on the tire and loading information label. See Loading Your Vehicle on page 4-29.
• are driven on reasonable road surfaces within legal
driving limits.
• use the recommended fuel. See Gasoline Octane
on page 5-5.
The services in Scheduled Maintenance on page 6-4
should be performed when indicated. See Additional Required Services on page 6-6 and Maintenance Footnotes on page 6-7 for further information.{CAUTION:
Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your GM Goodwrench® dealer to have a qualified technician do the work.
Some maintenance services can be complex. So, unless you are technically qualified and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. When you go to your GM Goodwrench® dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts. If you want to purchase service information, see Service Publications Ordering Information on page 7-11. Owner Checks and Services on page 6-8 tells you what should be checked, when to check it and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, fluids and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-12 and Normal Maintenance Replacement Parts on page 6-14. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine GM parts.
6-3
Scheduled Maintenance When the Service Engine Oil light on the trip computer display comes on, it means that service is required for your vehicle. See Trip Computer on page 3-33. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system may not indicate that vehicle service is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM parts and reset the system. If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 5-16 for information on the Engine Oil Life System and resetting the system.
When the Service Engine Oil light appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II, and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often. Maintenance I — Use Maintenance I if the light comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the light comes on 10 months or more since the last service or if the light has not come on at all for one year.

Maintenance Footnotes (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. (b) Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. (c) Visually inspect hoses and have them replaced if they are cracked, swollen, or deteriorated. Inspect all pipes, fittings and clamps; replace with genuine GM parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year. (d) Visually inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield.
(e) Make sure the safety belt reminder light and all your belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. The airbag system does not need regular maintenance. (f) Lubricate all key lock cylinders, door hinges and latches, hood hinges and latches, and trunk lid hinges and latches. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak.
6-7
(h) Change automatic transmission fluid and filter if the vehicle is mainly driven under one or more of these conditions:
− In heavy city traffic where the outside temperature
regularly reaches 90°F (32°C) or higher.
− In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as found in taxi, police, or delivery
service.
− Uses such as high performance operation.
