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.


(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 4-32.

(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.

(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 5-58, for inflation pressure adjustment for high speed driving.


Winter Tires If you expect to drive on snow or ice covered roads often, you may want to get winter tires for your vehicle. All season tires provide good overall performance on most surfaces but they may not offer the traction you would like or the same level of performance as winter tires on snow or ice covered roads. See your dealer for details regarding winter tire availability and proper tire selection. Also, see Buying New Tires on page 5-64
If you choose to use winter tires: (cid:127) Use tires of the same brand and tread type on all

four wheel positions.

(cid:127) Use only radial ply tires of the same size, load

range, and speed rating as the original equipment tires.

Winter tires with the same speed rating as your original equipment tires may not be available for H, V, W and ZR speed rated tires. If you choose winter tires with a lower speed rating, never exceed the tire’s maximum speed capability.


Tire Sidewall Labelling Useful information about a tire is molded into its sidewall. The example below shows a typical passenger (p-metric) 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.

(B) TPC Spec (Tire Performance Criteria Specification): Original equipment tires designed to GM’s specific tire performance criteria have a TPC specification code molded onto the sidewall. GM’s TPC specifications meet or exceed all federal safety guidelines. (C) DOT (Department of Transportation): The Department of Transportation (DOT) code indicates that the tire is in compliance with the U.S. Department of Transportation Motor Vehicle Safety Standards. (D) Tire Identification Number (TIN): The letters and numbers following DOT code are the Tire Identification Number (TIN). The TIN shows the manufacturer and plant code, tire size, and date the tire was manufactured. The TIN is molded onto both sides of the tire, although only one side may have the date of manufacture. (E) Tire Ply Material: The type of cord and number of plies in the sidewall and under the tread. (F) Uniform Tire Quality Grading (UTQG): Tire manufacturers are required to grade tires based on three performance factors: treadwear, traction and temperature resistance. For more information see Uniform Tire Quality Grading on page 5-65.

(G) Maximum Cold Inflation Load Limit: Maximum load that can be carried and the maximum pressure needed to support that load.

Tire Size The following illustration shows an example of a typical passenger (p-metric) vehicle tire size.

(A) Passenger (P-Metric) Tire: The United States version of a metric tire sizing system. The letter P as the first character in the tire size means a passenger vehicle tire engineered to standards set by the U. S. Tire and Rim Association.

(B) Tire Width: The three-digit number indicates the tire section width in millimeters from sidewall to sidewall.

(C) Aspect Ratio: A two-digit number that indicates the tire height-to-width measurements. For example, if the tire size aspect ratio is 60, as shown in item C of the illustration, it would mean that the tire’s sidewall is 60 percent as high as it is wide.


(D) Construction Code: A letter code is used to indicate the type of ply construction in the tire. The letter R means radial ply construction; the letter D means diagonal or bias ply construction; and the letter B means belted-bias ply construction.

(E) Rim Diameter: Diameter of the wheel in inches.

(F) Service Description: These characters represent the load range and speed rating of the tire. The load index represents the load carry capacity a tire is certified to carry. The load index can range from 1 to 279. The speed rating is the maximum speed a tire is certified to carry a load. Speed ratings range from A to Z.

Extended Mobility Tires Your vehicle, when new, had Goodyear Extended Mobility Tires (EMT). There’s no spare tire, no tire changing equipment and no place to store a tire in the vehicle. Extended Mobility Tires perform so well without any air that a Tire Pressure Monitor (TPM) is used to alert you if a tire has lost pressure. If a tire goes flat, you won’t need to stop on the side of the road to change the tire. You can just keep on driving. The shorter the distance you drive and the slower the speed, the greater the chance that the tire will not have to be replaced. If you drive on a deflated EMT for 25 miles (80 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tire can operate effectively with no air pressure for up to 100 miles (320 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. When a tire is filled with air, it provides a cushion between the road and the wheel.

Because you won’t have this cushion when driving on a deflated tire, try to avoid potholes that could damage your wheel and require replacement of it. Some road hazards can damage a tire beyond repair. This damage could occur even before you’ve driven on the tire in a deflated condition. When a tire has been damaged, or if you’ve driven any distance on a deflated EMT, check with an authorized Goodyear EMT Service Center to determine whether the tire can be repaired or should be replaced. To maintain your vehicle’s extended mobility feature, all replacement tires must be Extended Mobility Tires. As soon as possible, contact the nearest authorized GM or Goodyear EMT servicing facility for inspection and repair or replacement. To locate the nearest GM or Goodyear EMT servicing facility, call Roadside Assistance. For phone numbers and Roadside Assistance details see Roadside Assistance Program on page 7-6. You may also contact Goodyear, for the nearest authorized EMT servicing facility, by calling 1-800-789-9878.


Extended mobility tires are constructed differently than other tires and could explode during improper service. You or others could be injured or killed if you attempt to repair, replace, dismount, or mount a extended mobility tire. Let only an authorized EMT Service Center repair, replace, dismount and mount extended mobility tires.

The valve stems on your extended mobility tires have sensors that are part of the Tire Pressure Monitor (TPM). See Tire Pressure Monitor System on page 5-61. The TPM sensors contain batteries which are designed to last for 10 years under normal driving conditions. See your dealer if you ever need to have a wheel replaced, or if the sensors ever need replacement. Notice: Using liquid sealants can damage the tire valves and tire pressure monitor sensors in your extended mobility tires. This damage would not be covered by warranty. Don’t use liquid sealants in your extended mobility tires.


A Tire and Loading Information label is attached to the vehicle’s center pillar, below the driver’s door latch. This label lists your vehicle’s original equipment tires and shows 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 4-32. 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.

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


(cid:127) (cid:127) (cid:127) Tire Pressure Monitor System Your vehicle has a Tire Pressure Monitor (TPM) that sends tire pressure information to the Driver Information Center (DIC). Using the DIC control buttons, the driver is able to check tire pressure levels in all four tires. See Tire Pressure Monitor System on page 5-61
and DIC Controls and Displays on page 3-48 for additional information.

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’re 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.


High Speed Operation


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.

If you will be driving your vehicle at speeds of 175 mph (282 km/h) or higher, where it is legal, set the cold inflation pressure to the maximum inflation pressure shown on the tire sidewall, or 38 psi (265 kPa), whichever is lower. See the example following. When you end this high-speed driving, return the tires to the cold inflation pressure shown on the Tire and Loading Information label. See Loading Your Vehicle on page 4-32. Example: You will find the maximum load and inflation pressure molded on the tire’s sidewall, in small letters, near the rim flange. It will read something like this: Maximum load 690 kg (1521 lbs) 300 kPa (44 psi) Max. Press. For this example, you would set the inflation pressure for high-speed driving at 38 psi (265 kPa). Racing or other competitive driving may affect the warranty coverage of your vehicle. See your warranty booklet for more information.


Tire Pressure Monitor System The Tire Pressure Monitor (TPM) System on your vehicle, uses radio and sensor technology to check tire pressure levels. Sensors, mounted on each tire and wheel assembly transmit tire pressure readings to a receiver located in the vehicle. The TPM sensors transmit tire pressure readings once every 60 seconds while the vehicle is being driven and once every 60 minutes when the vehicle is stationary for more than 15 minutes. Using the Driver Information Center (DIC), tire pressure levels can be viewed by the driver. The TPM system also uses the DIC to warn the driver when air pressure, in one or more tires, falls below 24 psi (164 kPa) or is above 42 psi (290 kPa). For additional information and details about the DIC operation and displays see DIC Controls and Displays on page 3-48 and DIC Warnings and Messages on page 3-53. A low tire pressure warning light also appears on the instrument panel cluster when a low tire condition exists. The low tire pressure warning light will be shown each time the engine is started and stay on until the low tire condition is corrected.

When the tire pressure monitoring system warning light is lit, one or more of your tires is significantly under-inflated.

You should stop and check your tires as soon as possible, and inflate them to the proper pressure as indicated on the vehicle’s tire information placard. Driving on a significantly under-inflated tire causes the tire to overheat and can lead to tire failure. Under-inflation also reduces fuel efficiency and tire tread life, and may affect the vehicle’s handling and stopping ability. Each tire, including the spare, should be checked monthly when cold and set to the recommended inflation pressure as specified in the vehicle placard and owner’s manual. The Tire and Loading Information Label (tire information placard) is on the rear edge of the driver’s door, below the door latch. This label shows the size of your vehicle’s original tires and the correct inflation pressure for your vehicle’s tires when they are cold. See Loading Your Vehicle on page 4-32.


Your vehicle’s TPM system can alert you about a low or high tire pressure condition but it does not replace normal tire maintenance. See Inflation - Tire Pressure on page 5-58 and When It Is Time for New Tires on page 5-63. Each TPM sensor has a unique identification code that is matched to one of the four tire positions on your vehicle. The tire and wheel assembly positions are, left front (LF); right front (RF); right rear (RR) and left rear (LR). Any time you rotate your vehicle’s tires or replace one or more TPM sensors, the identification codes will need to be matched to the new tire and wheel position. The TPM matching process is performed in a specific sequence and time limit. A special tool is also required. See your dealer for service. The SERVICE TIRE MONITOR message is displayed when the TPM system is malfunctioning. For example, one or more TPM sensors may be inoperable or missing. Also, the active handlling system will be affected, see Active Handling System on page 4-10. See your dealer for service.

The TPM system operates on a radio frequency subject to Federal Communications Commission (FCC) Rules and with Industry and Science Canada. This device complies with Part 15 of the FCC Rules and with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received including interference that may cause undesired operation of the device. Changes or modifications to this system by other than an authorized service facility could void authorization to use this equipment.


Tire Rotation The tires on your vehicle are different sizes front to rear. Due to this, your tires should not be rotated. Each tire and wheel should be used only in the position it is in.

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: (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 can’t be repaired well because of the size or location of the damage.


(cid:127) (cid:127) (cid:127) Buying New Tires To find out what kind and size of tires you need, look at the Tire and Loading Information label. For information about this label and where to find it, see Loading Your Vehicle on page 4-32. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, GM recommends that you get tires with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, load range, traction, ride, tire pressure monitoring system performance and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an “MS” (for mud and snow). Whenever you replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires. If you replace your vehicle’s tires with those not having a TPC Spec number, the tire pressure monitoring system may give an inaccurate low-pressure warning. Non-TPC Spec tires may give a low-pressure warning that is higher or lower than the proper warning level you would get with TPC Spec numbered tires.



Mixing tires could cause you to lose control while driving. If you mix tires of different sizes (other than those originally installed on your vehicle) or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes (other than those originally installed on your vehicle) may also cause damage to your vehicle. Be sure to use the correct size and type tires on all four wheels.


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.

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.


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 wheels on your vehicle were aligned and balanced carefully at the factory to give you the longest tire life and best overall performance.

If you notice unusual tire wear or your vehicle pulling one way or the other, the alignment may need to be reset. If you notice your vehicle vibrating when driving on a smooth road, your wheels may need to be rebalanced.

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.




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 clearance to the body and chassis.

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 a crash. 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 you need to, to get all the rust or dirt off.




Never use oil or grease on studs or the threads of the wheel nuts. If you do, the wheel nuts might come loose and the wheel could fall off, causing a crash.

Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to become loose and even come off. This could lead to a crash. Be sure to use the correct wheel nuts. If you have to replace them, be sure to get new GM original equipment wheel nuts.

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.


Used Replacement Wheels

Tire Chains



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.


Lifting Your Vehicle


Lifting a vehicle can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to lift your vehicle. 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.

To be even more certain the vehicle won’t move, you can put blocks in front of and behind the wheels.


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.


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 place the jack in the proper location before raising the vehicle.

If you ever use a jack to lift your vehicle, follow the instructions that came with the jack, and be sure to use the correct lifting points to avoid damaging your vehicle.


Notice: Lifting your vehicle improperly can damage your vehicle and result in costly repairs not covered by your warranty. To lift your vehicle properly, follow the advice in this part. To help prevent vehicle damage: (cid:127) Be sure to place a block or pad between the

jack and the vehicle.

(cid:127) Make sure the jack you’re using spans at least

two crossmember ribs. Lift only in the areas shown in the following pictures.

For additional information, see your dealer and the Chevrolet Corvette service manual.

Lifting From the Front

The front lifting points can be accessed from either side of your vehicle, behind the front tires.


(cid:127) 1. Locate the front lifting points (A), according to the

illustration shown.

3. Lift the vehicle with the jack, making sure the jack

spans at least two of the crossmember ribs (B).

2. Be sure to place a block or pad between the jack

and the vehicle.


Lifting From the Rear

The rear lifting points can be accessed from the rear of the vehicle, on either the driver’s or passenger’s side.

1. Locate the rear lifting points (A), according to the

illustration shown.

2. Be sure to place a block or pad between the jack

and the vehicle.


It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. See Tires on page 5-51. If air goes out of a tire, it’s much more likely to leak out slowly. Your vehicle has Extended Mobility Tires (EMT), so you will not need to stop on the side of the road to change a flat tire. EMT tires can operate effectively with no air pressure. If you drive on a deflated EMT for 25 miles (80 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. Contact the nearest authorized Chevrolet or Goodyear EMT servicing facility, as soon as possible, to have the flat tire inspected and repaired or replaced. For more information, see Extended Mobility Tires on page 5-56.


Special tools and procedures are required to service an Extended Mobility Tire (EMT). If these special tools and procedures are not used you or others could be injured and your vehicle could be damaged. Always be sure the proper tools and procedures, as described in the service manual, are used.

To order a service manual, see Service Publications Ordering Information on page 7-11.

3. Lift the vehicle with the jack, making sure the jack

spans at least two of the crossmember ribs (B). For more information, see Doing Your Own Service Work on page 5-4.

If a Tire Goes Flat Your Corvette has no spare tire, no tire changing equipment and no place to store a tire.


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: (cid:127) Gasoline (cid:127) Benzene (cid:127) Naphtha (cid:127) Carbon Tetrachloride (cid:127) Acetone (cid:127) Paint Thinner

Turpentine Lacquer Thinner

(cid:127) 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: (cid:127) Alcohol

Laundry Soap

(cid:127) Bleach (cid:127) 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: (cid:127) Always read the instructions on the cleaner label. (cid:127) Clean up stains as soon as you can before they set. (cid:127) Carefully scrape off any excess stain. (cid:127) 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 fabric after spot cleaning, clean the entire area immediately or it will set.


(cid:127) (cid:127) (cid:127) (cid:127) 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.

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.

Coated Moldings These moldings are around the hatch opening in the rear area. (cid:127) When lightly soiled, wipe with a sponge or soft

lint-free cloth dampened with water.

(cid:127) When heavily soiled, use warm soapy water.

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.

(cid:127) Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish, or shoe polish on leather.

(cid:127) 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.


(cid:127) Cargo Cover and Convenience Net Wash with warm water and mild detergent, rinse with cold water and tumble dry on low. Do not use chlorine bleach.

Glass Surfaces Glass should be cleaned often. GM Glass 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. Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger and the integrated radio antenna. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner.

If you use abrasive cleaners when cleaning

Care of Safety Belts Keep belts clean and dry.


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.

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 6-11.


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.

If you drive your vehicle through an

Notice: automatic car wash that does not have enough clearance for the wide rear tires and wheels, you could damage your vehicle. Verify with the manager of the car wash that your vehicle will fit before entering the car wash or use a touchless car wash. High pressure car washes may cause water to enter the vehicle. If you are cleaning your vehicle with the hood open, take care not to spray water directly into either end of the air cleaner/filter housing as this could damage your vehicle’s engine. See Engine Air Cleaner/Filter on page 5-19 for more information.

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 5-79.


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. 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. 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. 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 a glass treatment and/or

Removable Roof Panel Notice: conditioner that contains ethyl alcohol or ethyl sulfate on the roof panel, you could damage the panel. The repairs would not be covered by your warranty. Only use a GM-approved glass cleaner on the roof panel. Special care is necessary when cleaning, removing, and/or storing the roof panel.

Flush with water to remove dust and dirt, then dry the panel.

(cid:127) Clean a transparent roof panel with GM Glass

Cleaner. Leave the cleaner on the panel for one minute, then wipe the panel with a soft, lint-free cloth. Do not use glass cleaner on a painted roof panel.

(cid:127) Do not use abrasive cleaning materials on either type

of panel.

If water drops are frequently allowed to dry on the roof panel, impurities in the water will adhere to the top. These impurities may etch or mar the finish. When the panel gets wet, dry it off.

Convertible Top The vehicle’s convertible top should be cleaned often. However, high pressure car washes may cause water to enter your vehicle. When you hand wash the top, do it in partial shade. Use a mild soap, lukewarm water and a soft sponge. A chamois or cloth may leave lint on the top, and a brush can chafe the threads in the top fabric. Do not use detergents, harsh cleaners, solvents or bleaching agents. Wet the entire vehicle and wash the top evenly to avoid spots or rings. Let the soap remain on the fabric for a few minutes. When the top is really dirty, use a mild foam-type cleaner. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight. To protect the convertible top: (cid:127) After you wash the vehicle, make sure the top is

completely dry before you lower it.

(cid:127) Do not get any cleaner on the vehicle’s painted

finish; it could leave streaks. If you decide to go through an automatic car wash, ask the manager if the equipment could damage your top.


(cid:127) (cid:127) 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.


Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Minor chips and scratches can be repaired with touch-up materials avaliable from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.

If you use acidic or corrosive cleaning

Fiberglass Springs Notice: products, engine degreasers or aluminum cleaning agents on fiberglass springs, you may damage the springs. The repairs would not be covered by your warranty. Use only approved cleaners when cleaning your vehicle’s fiberglass springs.

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 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.


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 air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-51.

Headlamp Wiring The headlamp wiring is protected by fuses. An electrical overload will cause the lamps to remain off. If this happens, have your headlamp wiring checked right away.

Windshield Wiper Fuses The windshield wiper motor is protected by a fuse and an internal circuit breaker. 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 and not snow, etc., be sure to get it fixed.

Power Windows and Other Power Options Circuit breakers protect the power seats, 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 or goes away.


Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of J-Case fuses, mini-fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems. 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. 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 correct amperage. Replace it as soon as you can.


Instrument Panel Fuse Block The instrument panel fuse block is located on the passenger’s side of the vehicle, under the instrument panel and under the toe-board. Remove the carpet and toe-board covering to access the fuse block by pulling at the top of each corner of the panel. Then turn the fuse block door knob counterclockwise and pull the door to access the fuses. You can remove fuses using the fuse puller.

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.

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 Your 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 4-32. 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.


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.


(cid:127) (cid:127) (cid:127) 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 6-11 and Normal Maintenance Replacement Parts on page 6-13. 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.

Scheduled Maintenance When the CHANGE OIL SOON message comes on, it means that service is required for your vehicle. 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, your 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 5-18 for information on the Engine Oil Life System and resetting the system. When the CHANGE OIL SOON message 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 message 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 message comes on 10 months or more since the last service or if the message has not come on at all for one year.
