2003 Chevrolet Corvette Owners Manual

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 Ct-

rolet V ’ rranty booklet for details.

Poorly maintained and improperly used tires are dangerous.

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’’ in the Index. 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.

CAUTION:

(Continued)

0 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. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them.

Extended Mobility Tires (Except Z06) 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 50 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 200 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. Fsr phsne nE!?hers 2nd REdSidf? .A.ssistsnce dPf?!l!S see Roadside Assistance Program on page 7-5. You may also contact Goodyear, for the nearest authorized EMT servicing facility, by calling 1-800-789-9878.

Let only an authorized Goodyear 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 (Except Z06) on page 5-57. These 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.

5-55

If you feel that winter tires are needed for your driving conditions, Goodyear Eagle M+S EMT tires are available in your original equipment sizes from an authorized Goodyear EMT retailer. These tires will improve snow traction while maintaining your vehicle’s extended mobility feature. When using winter tires on your vehicle, be sure to use them on all four wheels. See Buying New Tires on page 5-59.

Inflation -- Tire Pressure

Information label, which is on the rear

The Tire-Loading edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). Notice: Don’t let anyone tell you that underinflation or overinflation is all right. It’s not. If your tires don’t have enough air (underinflation), you can get the following:

Too much flexing Too much heat Tire overloading Bad wear Bad handling Bad fuel economy

5-56

If your tires have too much air (overinflation), you can get the following:

Unusual wear Bad handling Rough ride Needless damage from road hazards

When to Check Check your tires once a month or more. 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. Be sure to put the valve caps back on the valve stems. They help prevent leaks by keeping out dirt and moisture. If your vehicle is equipped with the Tire Pressure Monitor, you can check tire inflation pressures while driving. After you’ve reached a speed of 15 mph (24 kmh) or more, press and release the GAGES button on the Driver Information Center (DIC) until the front tire pressures are displayed. Then, press and release the GAGES button for the rear tire pressures.

Monitor System

If the display doesn’t show tire pressure, or if the SERVICE TIRE MON SYS message appears see your dealer for service. For more information, see Tire Pressure Monitor System (Except Z06) on page 5-57 and Driver Information Center (DIC) on page 3-44. Tire Pressure (Except Z06) The Tire Pressure Monitor (TPM) has a sensor on each road wheel that transmits to a receiver on the instrument panel. The 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. 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 operaiion.

This device complies with RSS-210 of Industry and Science Canada. Operation is subject to the following two conditions: (1) this device may not cause 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. If a tire’s inflation pressure is between 5 psi (35 kPa) and 25 psi (1 70 kPa), you will see a message on the Driver Information Center. This message will show which tire is underinflated and two chimes will sound. An example would be LOW TIRE PRESSURE-LR. This would mean that the inflation pressure in your left rear tire is between 5 psi (35 kPa) and 25 psi (1 70 kPa). If the inflation pressure in the tire drops below 5 psi (35 kPa), the message would read FLAT TIRE-LR and four chimes will sound. See Driver Information Center (DIC) on page 3-44. The TPM will also alert you if a tire’s nressure is higher than 42 psi (290 kPa). The message will show which tire is overinflated and two chimes will sound. An example would be HIGH PRESSURE-LR. This would mean that the inflation pressure in your left rear tire is higher than 42 psi (290 kPa). See Driver Information Center p ! q o!? p g e 2-44.

5-57

If a tire pressure message appears on the Driver Information Center, stop as soon as you can. Have the tire pressures checked and set to those shown on your Tire-Loading Information label. See inflation -- Tire Pressure on page 5-56.

en th

.OW TIRE PRESSURE or FLAT TIRE message is displayed on the Driver Information Center, your vehicle’s handling capabilities will be reduced during severe maneuvers. If you drive too fast, you could lose control of your vehicle. You or others could be injured. Don’t drive over 55 mph (90 km/h) when the LOW TIRE PRESSURE or FLAT TIRE message is displayed. Drive cautiously, and check your tire pressures as soon as you can.

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.

5-58

When It’s 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 around the tire. 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.

Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Information label. 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, get ones 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, traction, ride 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). If you ever 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.

the vehicle m - not handle p -)erly, 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 your vehicle is equipped with Extended Mobility Tires and you feel that winter tires are needed, see Extended Mobility Tires (Except Z--’

I page 5-54.

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.

5-59

Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A The following information relates to the system developed by the United States National Highway Traffic Safety Administration, which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.) The grades are molded on the sidewalls of most passenger car tires. The Uniform Tire Quality Grading system does not apply to deep tread, winter-type snow tires, space-saver or temporary use spare tires, tires with nominal rim diameters of 10 to 12 inches (25 to 30 cm), or to some limited-production tires. While the tires available on General Motors passenger cars and light trucks may vary with respect to these grades, they must also conform to federal safety requirements and additional General Motors Tire Performance Criteria (TPC) standards.

Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions on a specified government test course. For example, a tire graded 150 would wear one and a half (1 -5) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction - AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.

5-60

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. Scheduled wheel alignment and wheel balancing are not needed. However, 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. Yollr dealer will know the kind nf wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.

5-6 1

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 re1 cement 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.

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.

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.

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.

5-62

Incorrect wheel nuts or improperly llyhtened 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.

Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the whee! nuts in the proper sequence and to the proper torque specification.

Magnesium Wheels

Notice: If your vehicle has magnesium wheels, I moisture on or around the mounting surface of the

magnesium wheel will cause corrosion and damage to the wheel. To help prevent this, a magnesium wheel has two rubber O-rings. One goes on the inboard side of the wheel and the other on the back of the center hubcap. When you put a magnesium wheel back on, be sure the O-rings are correctly installed. On the inboard side, work the O-ring into the groove. When properly installed, this O-ring fits snugly. The other O-ring goes around the edge of the center cap. Used Replacement Wheels

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.

5-63

Tire Chains

--

Lifting Your Corvette

.,..IS. Therc

Don’t use tire not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels. If you do find traction devices that will fit, install them on the rear tires.

Lifting a veh- - - e 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). Turn off the engine.

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.

5-64

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 Corvette, such as to display it at a show, 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: * Be sure to place a block or pad between the

jack and the vehicle.

Special tools and procedures are required to service an Extended Mobility Tire (EMT). If these special tools and procedures aren’t 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 and Owner Publications” in the Index.

If a Tire Goes Flat

Your Corvette has no spare tire, no tire changing equipment and no place to store a tire. It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. See “Tires” in the Index. If air goes out of a tire, it’s much more likely to leak out slowly. If your vehicle has Extended Mobility Tires (EMT), you won’t 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 50 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” in the Index.

5-68

Z06 models do not have Extended Mobility Tires. If a Z06 model tire goes flat, avoid further tire and wheel damage by driving slowly to a level place and stopping. Then do this: 1. Turn on the hazard warning flashers. 2. Set the parking brake firmly. 3. Put the shift lever (manual transmission) in

REVERSE (R).

4. Turn off the engine. 5. Inspect the flat tire. If the tire has been separated from the wheel or has damaged sidewalls or large tears that allow rapid air IOSS, Assistance” in the Index.

call a tire repair facility. See “Roadside

If the flat tire is due to a slow leak caused by a nail or other similar road hazard, the tire inflator kit may be used to repair the damaged tire temporarily. The kit uses a liquid tire sealant to seal small punctures in the tread area of the tire. The flat tire is then inflated to at least 26 psi (1 79 kPa) and driven to evenly distribute the tire sealant. The tire pressure is checked after driving for a maximum of 10 minutes to see if the slow leak has been stopped. If the tire pressure is 19 psi (131 kPa) or more, inflate the tire up to the standard operating pressure as shown on the Tire Pressure Label found on the rear edge of the driver’s door. See “Tires, Pressure” in the Index. You should have the damaged tire repaired as soon as possible. The tire sealant is a temporary repair only. For more information regarding the tire inflator kit see “Tire Inflator Kit” following this section. Notice: If the tire pressure has dropped below 19 psi (131 kPa), the vehicle should not be driven further. Damage to the tire may be severe and the sealant will not be effective. Contact Roadside Assistance. See “Roadside Assistance” in the Index.

5-69

Tire Inflator Kit (Z06 Only) Every Z06 model with P295/35ZR18 and P265/402Rl7 tires, when new, was equipped with a tire inflator kit. The repair kit contains a detailed instruction card that outlines step by step the temporary repair procedure. Be sure to read and follow all the tire inflator kit instructions. The kit also includes:

Accessory Plug E. Air Compressor

Inflator Hose

F. Air Pressure Gage G. Sealant Filling

Hose Plug

H. Valve Core Remover I. Spare Valve Core J. 55-mph Label

Tire Sealant The kit contains a liquid sealant that when injected into a flat tire, may temporarily repair nail holes or cuts in the tread area of the tire. The tire sealant cannot repair tire damage caused while driving on a flat tire or a tire that has had a “blow out” or a tire that has punctures in the sidewall areas. The tire sealant solution is a one-time use application for one tire only. Check the tire sealant expiration date; the sealant may not be as effective beyond the expiration date. The tire sealant can be peeled off easily after drying.

Notice: Do not use a tire sealant if your vehicle is equipped with Extended Mobility Tires or tire pressure monitors. The tire sealant can damage tire pressure monitor sensors. See “Extended Mobility Tires” in the Index. Air Compressor The air compressor included in the tire inflator kit, was designed exclusively for the Z06 Model equipped with P295/35ZR18 and P265/40ZR17 tires. After the sealant has been injected into the flat tire, use the air compressor to inflate the tire to at least 26 psi (179 kPa). Instructions for connecting and using the air compressor are iocateci on the air Compressor.

A. Inflating Hose B. Air Pressure Gage

C. ON/OFF Switch D. Air Compressor Plug Notice: The car engine must be running to avoid draining the battery while running the air compressor. Follow the proper steps to be sure your vehicle won’t move. See Parking Your Vehicle (Manual Transmission) on page 2-34.

5-71

It can be dangerous to get out of your vehicle with the engine running, if the shift lever is not in NEUTRAL (N) with the parking brake firmly set (manual transmission). Your vehicle can roll or move suddenly even when on fairly level ground. To be sure your vehicle won’t move, always set your parking brake and move the shift lever to NEUTRAL (N) when you start or idle your engine.

Idling the engine in a closed-in place or with the climate control system off can cause deadly carbon monoxide (CO). See “Engine Exhaust” in the Index.

5-72

Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate the tire to its recommended pressure. Do not exceed 36 psi (248 kPa).

Notice: Do not allow the air compressor to operate continuously for more than six minutes to help prevent damage from overheating.

Notice: If 26 psi (179 kPa) tire pressure cannot be reached after six minutes the vehicle should not be driven further. Damage to the tire is severe and the sealant will not be effective. Remove the air compressor plug from the accessory power outlet and unscrew the inflating hose from the tire valve. See “Roadside Assistance” in the Index. If 26 psi (1 79 kPa) tire pressure is reached in six minutes or less, disconnect the air compressor and attach the enclosed maximum speed label to the inside upper left corner of the windshield or to the face of the radio/clock.

Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flames if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle:

Gasoline Benzene 0 Naphtha 0 Carbon Tetrachloride 0 Acetone

Paint Thinner 0 Turpentine 0 Lacquer Thinner 0 Nail Polish Remover They can all be hazardous - some more than others -and

they can all damage your vehicle, too.

Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: 0 Alcohol 0 Laundry Soap 0 Bleach 0 Reducing Agents Cleaning the Inside of Your Vehicle 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. FabricKarpet Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. You can get GM-approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on paqe 5-82.

5-75

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. If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.

Coated Moldings These moldings are around the hatch opening in the rear area.

When lightly soiled, wipe with a sponge or soft lint-free cloth dampened with water. 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. See your dealer for this product. 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.

Top of the 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 windshield and even make it difficult to see through the windshield under certain conditions.

Cleaning the Outside of Your Vehicle The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Use a car washing soap. Don’t use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. You can get GM-approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on page 5-82. Don’t 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 your vehicle. Notice: Conveyor systems on some automatic car washes may damage your vehicle. They may not have enough clearance for the undercarriage or for the wide rear tires. Check with the manager before using a car wash.

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.” Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on page 5-82. If your vehicle has a “basecoatlclearcoat” 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 basecoatlclearcoat paint finish. Notice: Machine compounding or aggressive polishing on a basecoatlclearcoat paint finish may dull the finish or leave swirl marks. 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 your 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.

Removable Roof Panel Special care is necessary when cleaning, removing and/or storing the roof panel. 0 Flush with water to remove dust and dirt, then dry

the panel.

0 Clean the panel with GM Glass Cleaner. Leave the cleaner on the panel for one minute, then wipe the panel with a soft, lint-free cloth.

0 Don’t use abrasive cleaning materials If water drops are frequently allowed to dry on roof panel, impurities in the water will adhere to the top. These impurities may etch or mar the finish. When the panel gets wet, you should dry it off. Notice: Do not use a glass treatment or conditioner containing ethyl alcohol or ethyl sulfate on the roof panel. These products may damage the panel.

Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your vehicle garaged 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 full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. If you use a glass treatment or conditioner containing ethyl alcohol or ethyl sulfate on your glass, be sure to remove the acrylic roof panel, if so equipped. These products may damage the panel. 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 tull-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.

Convertible Top Your convertible top should be cleaned often. If you use an automatic car wash, use one with water jets and hanging cloths. 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. Don’t 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. Your dealer has a Convertible Top Cleaner and Water Repellent. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight. To protect the convertible top: * After you wash the vehicle, make sure the top is

completely dry before you lower it. Don’t 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.

5-80

Aluminum Wheels Keep your 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. The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. Don’t take your 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 your tires, use a stiff brush with tire cleaner. Notice: When applying a tire dressing, always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle. Petroleum-based products may damage the paint finish and tires.

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. Magnesium Wheel Finish Notice: Improper paint repair or refinishing can cause corrosion damage to a magnesium wheel. See your dealer if a magnesium wheel needs paint repair or refinishing. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur 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.

Titanium Exhaust System (Z06 Only)

Time and high performance driving conditions can cause a color change in titanium exhaust system parts. This is normal for a titanium surface.

Fiberglass Springs

Notice: Don’t use corrosive or acidic cleaning agents, engine degreasers, aluminum cleaning agents or other harsh solvents to clean fiberglass springs; they’ll damage the springs.

To use the accessory power plug, do the following:

1, Remove the toe-board panel by pulling at the top of

each corner of the panel.

2. Locate the black connector at the top left corner of

the compartment near the body control module above the two white diagnostic connectors.

3. Disconnect the connector pigtail by pulling forward

on the plastic locking tab and pull the connection apart from the wire harness.

The plug has the following three separate wires: The orange wire connects to battery power. The yellow wire connects to ignition power. (Power is only available when the ignition is in ON.) The black wire connects to ground.

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 Air Bag-Equipped Vehicle on page 1-47. Accessory Power Plug The accessory power plug can be used to connect electrical equipment such as a cellular phone or CB radio. It is located behind the carpeting, on the passenger’s side toe-board, at the top left corner near the body control module. Be sure to follow the installation instructions included with the equipment.

5-84

e

Notice: When using the accessory power plug:

Do NOT splice wires directly into the vehicle electrical wire harness. If done incorrectly, spicing may cause damage to your electrical system and would not be covered by the vehicle’s warranty. The maximum load of any electrical equipment should not exceed 15 amps. Be sure to turn off any electrical equipment when not in use. Leaving electrical equipment on for extended periods of time can drain your battery. DO NOT use this plug if the electrical equipment requires frequent connecting and disconnecting. This may cause excessive wear on the accessory power plug and damage your electrical system and the damage would not be covered by your warranty.

Headlamp Wiring The headlamp wiring is protected by a circuit breaker. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. Windshield Wiper Fuses The windshield wiper motor is protected by 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 and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is tlxed or goes away.

5-85

Fuses and Circuit 5reakers

instrument Panel Fuse Block

The wiring circuits in your vehicle are protected from short circuits by a combination of maxi-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 don’t 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.

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.

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 procedures are 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, please maintain your vehicle properly. Maintenance Requirements Maintenance intervals, checks, inspections 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 recommended maintenance may not be covered by warranty.

Maintenance Schedule

Introduction

IMPORTANT: KEEP ENGINE OIL AT THE PROF

LEVEL AND CHAluut 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.

6-2

How This Section is Organized This maintenance schedule is divided into five parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs.

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, have a qualified technician do the work.

If you want to get the service information, see Service Publications Ordering Information on page 7- IO.

“Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what you can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department or another qualified service center should perform. “Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part: E: Maintenance Recsrd” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

6-3

Part A: Scheduled Maintenance Services This part contains engine oil scheduled maintenance which explains the engine oil life system and how it indicates when to change the engine oil and filter. Also, listed are scheduled maintenance services which are to be performed at the mileage intervals specified. Using Your Maintenance Schedule We at General Motors want to keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive 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 the different ways people use their vehicles, maintenance needs may vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have questions on how to keep your vehicle in good condition, see your dealer. This part tells you the maintenance services you should have done and when you should schedule them. When you go to your dealer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts.

6-4

The proper fluids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. This schedule is for vehicles that:

carry passengers and cargo within recommended limits. You will find these on your vehicle’s Tire-Loading Information label. See Loading Your Vehicle on page 4-33. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 5-5.

Scheduled Maintenance The services shown in this schedule up to 100,000 miles (1 66 000 km) should be repeated after 100,000 miles (1 66 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6-7, Part C: Periodic Maintenance Inspections on page 6-1 I and Part D: Recommended Fluids and Lubricants on page 6- 13.

Footnotes t The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emissions warranty or limit recall liability prior to the completion of the vehicle's useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. Engine Oil Scheduled Maintenance Change engine oil and filter as indicated by the Engine Oil Life System@ (or every 12 months, whichever occurs first). Reset the system. Your vehicle has a computer system that lets you know when to change the engine oil and filter. This is based on engine revolutions and engine temperature, and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can varv considerablv. For the oil life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. A CHANGE OIL SOON message will come on. Change your oii as soon as possibie within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life

system may not indicate that an oil change 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. It is also important to check your oil regularly and keep it at the proper level. If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. See Engine Oil on page 5-13 for information on resetting the system. Use engine oil meeting the GM Standard GM4718M. After the services are performed, record the date, odometer reading and who performed the service on the maintenance record pages in part E of this schedule.
