Automatic Transmission Fluid How to Check It is not necessary to check the transmission fluid level. A transmission fluid leak is the only reason for fluid loss. If a leak occurs, take the vehicle to your dealer service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid. Because this procedure is difficult, you should have this done at your dealer service department. Contact your dealer for additional information or the procedure can be found in the service manual. To purchase a service manual, see “Service and Owner Publications” in the Index.

Change both the fluid and filter every 50,000 miles (80 000 km) if the vehicle is mainly driven under one of these conditions: D In heavy city traffic where the outside temperature

regularly reaches 90_F (32_C) or higher.

D In hilly or mountainous terrain. D High performance operation. If you do not use your vehicle under one of these conditions, change the fluid and filter every 100,000 miles (166 000 km). See “Scheduled Maintenance Services” in the Index for the proper service intervals for the transmission fluid and filter.

NOTICE:

We recommend that only fluid labeled DEXRONR-III be used, because fluid with that label is made specially for your automatic transmission. Damage caused by fluid other than DEXRONR-III is not covered by your new vehicle warranty.

6-19

Manual Transmission Fluid When to Check A good time to have it checked is when the engine oil is changed. However, the fluid in your manual transmission doesn’t require changing. How to Check Because this operation can be difficult, you may choose to have this done at your Chevrolet dealership service department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading.

NOTICE:

Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot exhaust system parts, starting a fire. Too little fluid could cause the transmission to overheat. Be sure to get an accurate reading if you check your transmission fluid.

6-20

Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case. Then, follow these steps:

1. Remove the filler plug. 2. Check that the lubricant level is up to the bottom of

the filler plug hole.

3. If the fluid level is good, install the plug and be sure

it is fully seated. If the fluid level is low, add more fluid as described in the next steps.

How to Add Fluid Here’s how to add fluid. Refer to the Maintenance Schedule to determine what kind of fluid to use. See “Recommended Fluids and Lubricants” in the Index. 1. Remove the filler plug. 2. Add fluid at the filler plug hole. Add only enough fluid to bring the fluid level up to the bottom of the filler plug hole.

3. Install the filler plug. Be sure the plug is fully seated. 4. Tighten the plug to 20 lb-ft (27 N·m).

Hydraulic Clutch The hydraulic clutch linkage in your vehicle is self-adjusting. The clutch master cylinder reservoir is filled with hydraulic clutch fluid. It is not necessary to regularly check clutch fluid unless you suspect there is a leak in the system. Adding fluid won’t correct a leak. A fluid loss in this system could indicate a problem. Have the system inspected and repaired.

When to Check and What to Use

The clutch master cylinder reservoir is located at the rear of the engine compartment on the driver’s side. See “Engine Compartment Overview” in the Index for more information on location. Refer to the Maintenance Schedule to determine how often you should check the fluid level in your clutch master cylinder reservoir and for the proper fluid. See “Owner Checks and Services” and “Recommended Fluids and Lubricants” in the Index.

6-21

How to Check and Add Fluid

Rear Axle When to Check Lubricant Refer to the Maintenance Schedule to determine how often to check the lubricant. See “Periodic Maintenance Inspections” in the Index. How to Check Lubricant

Fluid should be added if the fluid level is below the step on the inside of the reservoir. There are additional instructions on the reservoir cap. Put the rubber seal and cap back on. See “Engine Compartment Overview” in the Index for more information on location.

6-22

To get an accurate reading, the vehicle should be on a level surface.

If the level is below the bottom of the filler plug hole, you’ll need to add some lubricant. Add enough lubricant to raise the level to the bottom of the filler plug hole. What to Use To add lubricant when the level is low, use SAE 75W-90
Synthetic Gear Lubricant (GM Part No. 12378261) or equivalent meeting GM Specification 9986115. To completely refill after draining, add 4 ounces (118 ml) of Limited-Slip Differential Lubricant Additive (GM Part No. 1052358) or equivalent. Then fill to the bottom of the filler plug hole with the Synthetic Gear Lubricant.

Engine Coolant The cooling system in your vehicle is filled with DEX-COOLR engine coolant. This coolant is designed to remain in your vehicle for 5 years or 150,000 miles (240 000 km), whichever occurs first, if you add only DEX-COOLR extended life coolant. The following explains your cooling system and how to add coolant when it is low. If you have a problem with engine overheating, see “Engine Overheating” in the Index.

A 50/50 mixture of clean, drinkable water and DEX-COOLR coolant will: D Give freezing protection down to -34_F (-37_C). D Give boiling protection up to 265_F (129_C). D Protect against rust and corrosion. D Help keep the proper engine temperature. D Let the warning lights and gages work as

they should.

NOTICE:

When adding coolant, it is important that you use only DEX-COOLR (silicate-free) coolant. If coolant other than DEX-COOL is added to the system, premature engine, heater core or radiator corrosion may result. In addition, the engine coolant will require change sooner -- at 30,000 miles (50 000 km) or 24 months, whichever occurs first. Damage caused by the use of coolant other than DEX-COOLR is not covered by your new vehicle warranty.

6-23

What to Use Use a mixture of one-half clean, drinkable water and one-half DEX-COOLR coolant which won’t damage aluminum parts. If you use this coolant mixture, you don’t need to add anything else.

CAUTION:

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid such as alcohol, can boil before the proper coolant mixture will. Your vehicle’s coolant warning system is set for the proper coolant mixture. With plain water or the wrong mixture, your engine could get too hot but you wouldn’t get the overheat warning. Your engine could catch fire and you or others could be burned. Use a 50/50 mixture of clean, drinkable water and DEX-COOLR coolant.

NOTICE:

If you use an improper coolant mixture, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mixture can freeze and crack the engine, radiator, heater core and other parts.

If you have to add coolant more than four times a year, have your dealer check your cooling system.

NOTICE:

If you use the proper coolant, you don’t have to add extra inhibitors or additives which claim to improve the system. These can be harmful.

6-24

Checking Coolant

The coolant surge tank is located in the engine compartment behind the passenger’s side headlamp. See “Engine Compartment Overview” in the Index for more information on location.

CAUTION:

Turning the surge tank pressure cap when the engine and radiator are hot can allow steam and scalding liquids to blow out and burn you badly. Never turn the surge tank pressure cap -- even a little -- when the engine and radiator are hot.

The vehicle must be on a level surface. When your engine is cold, the coolant level should be at the FULL COLD mark. The FULL COLD mark is on the front of the coolant surge tank. Don’t overfill the surge tank. Too much coolant can result in an overflow when the fluid is hot.

6-25

Adding Coolant If you need more coolant, add the proper DEX-COOLR coolant mixture at the surge tank, but only when the engine is cool.

Surge Tank Pressure Cap

NOTICE:

CAUTION:

You can be burned if you spill coolant on hot engine parts. Coolant contains ethylene glycol, and it will burn if the engine parts are hot enough. Don’t spill coolant on a hot engine.

The surge tank pressure cap is a 15 psi (105 kPa) pressure-type cap and must be tightly installed to prevent coolant loss and possible engine damage from overheating.

See “Engine Compartment Overview” in the Index for information on location.

When replacing the pressure cap, make sure it is hand-tight.

6-26

Power Steering Fluid

When to Check Power Steering Fluid It is not necessary to regularly check power steering fluid unless you suspect there is a leak in the system or you hear an unusual noise. A fluid loss in this system could indicate a problem. Have the system inspected and repaired. See “Engine Compartment Overview” in the Index for reservoir location.

How to Check Power Steering Fluid Turn the key off, let the engine compartment cool down, wipe the cap and the top of the reservoir clean, then unscrew the cap and wipe the dipstick with a clean rag. Replace the cap and completely tighten it. Then remove the cap again and look at the fluid level on the dipstick. The level should be at the FULL COLD mark. If necessary, add only enough fluid to bring the level up to the mark.

D When the engine

compartment is hot, the level should be at the HOT mark.

D When the engine

compartment is cool, the level should be at the FULL COLD mark.

What to Use To determine what kind of fluid to use, see “Recommended Fluids and Lubricants” in the Index. Always use the proper fluid. Failure to use the proper fluid can cause leaks and damage hoses and seals.

6-27

Windshield Washer Fluid What to Use When you need windshield washer fluid, be sure to read the manufacturer’s instructions before use. If you will be operating your vehicle in an area where the temperature may fall below freezing, use a fluid that has sufficient protection against freezing. See “Engine Compartment Overview” in the Index for reservoir location. Adding Washer Fluid

Open the cap with the washer symbol on it. Add washer fluid until the tank is full.

NOTICE:

D When using concentrated washer fluid,

follow the manufacturer’s instructions for adding water.

D Don’t mix water with ready-to-use washer fluid. Water can cause the solution to freeze and damage your washer fluid tank and other parts of the washer system. Also, water doesn’t clean as well as washer fluid.

D Fill your washer fluid tank only

three-quarters full when it’s very cold. This allows for expansion if freezing occurs, which could damage the tank if it is completely full.

D Don’t use engine coolant (antifreeze) in your windshield washer. It can damage your washer system and paint.

6-28

Brakes Brake Fluid

Your brake master cylinder reservoir is on the driver’s side of the engine compartment. It is filled with DOT-3
brake fluid. See “Engine Compartment Overview” in the Index. There are only two reasons why the brake fluid level in the reservoir might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear.

When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak means that sooner or later your brakes won’t work well, or won’t work at all. So, it isn’t a good idea to “top off” your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.

CAUTION:

If you have too much brake fluid, it can spill on the engine. The fluid will burn if the engine is hot enough. You or others could be burned, and your vehicle could be damaged. Add brake fluid only when work is done on the brake hydraulic system. See “Checking Brake Fluid”in this section.

6-29

Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections” in the Index.

Checking Brake Fluid You can check the brake fluid without taking off the cap. Just look at the brake fluid reservoir. The fluid level should be above the MIN mark on the reservoir. If it isn’t, have your brake system checked to see if there is a leak. After work is done on the brake hydraulic system, make sure the level is between the MIN and MAX marks.

What to Add When you do need brake fluid, use only DOT-3 brake fluid. Use new brake fluid from a sealed container only. See “Recommended Fluids and Lubricants” in the Index. Always clean the brake fluid reservoir cap and the area around the cap before removing it. This will help keep dirt from entering the reservoir.

6-30

CAUTION:

With the wrong kind of fluid in your brake system, your brakes may not work well, or they may not even work at all. This could cause a crash. Always use the proper brake fluid.

NOTICE:

D Using the wrong fluid can badly damage

brake system parts. For example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced. Don’t let someone put in the wrong kind of fluid.

D If you spill brake fluid on your vehicle’s painted surfaces, the paint finish can be damaged. Be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

Brake Wear Your vehicle has four-wheel disc brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).

CAUTION:

The brake wear warning sound means that soon your brakes won’t work well. That could lead to an accident. When you hear the brake wear warning sound, have your vehicle serviced.

NOTICE:

Continuing to drive with worn-out brake pads could result in costly brake repair.

Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. Brake linings should always be replaced as complete axle sets. See “Brake System Inspection” in Section 7 of this manual under Part C “Periodic Maintenance Inspections.” Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble.

6-31

Battery Your new vehicle comes with a maintenance free ACDelcoR battery. When it’s time for a new battery, get one that has the replacement number shown on the original battery’s label. We recommend an ACDelco battery. For battery replacement, see your dealer or the service manual. To purchase a service manual, see “Service and Owner Publications” in the Index. WARNING: Battery posts, terminals and related accessories contain lead and lead compounds, chemicals known to the State of California to cause cancer and reproductive harm. Wash hands after handling.

Brake Adjustment As you make brake stops, your disc brakes automatically adjust for wear. Replacing Brake System Parts The braking system on a vehicle is complex. Its many parts have to be of top quality and work well together if the vehicle is to have really good braking. Your vehicle was designed and tested with top-quality GM brake parts. When you replace parts of your braking system -- for example, when your brake linings wear down and you need new ones put in -- be sure you get new approved GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong for your vehicle, the balance between your front and rear brakes can change -- for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts.

6-32

Vehicle Storage If you’re not going to drive your vehicle for 25 days or more, remove the black, negative (-) cable from the battery. This will help keep your battery from running down.

CAUTION:

Batteries have acid that can burn you and gas that can explode. You can be badly hurt if you aren’t careful. See “Jump Starting” in the Index for tips on working around a battery without getting hurt.

Contact your dealer to learn how to prepare your vehicle for longer storage periods. Also, for your audio system, see “Theft-Deterrent Feature” in the Index.

Bulb Replacement For the proper type of replacement bulb, see “Replacement Bulbs” in the Index. For any bulb changing procedure not listed in this section, contact your Chevrolet dealer’s service department. Halogen Bulbs

CAUTION:

Halogen bulbs have pressurized gas inside and can burst if you drop or scratch the bulb. You or others could be injured. Be sure to read and follow the instructions on the bulb package.

Windshield Wiper Blade Replacement Windshield wiper blades should be inspected at least twice a year for wear or cracking. See “Wiper Blade Check” in the index for more information. Replacement blades come in different types and are removed in different ways. For the proper type and length, see “Normal Maintenance Replacement Parts” in the Index. It’s a good idea to clean or replace the wiper blade assembly every six months.

NOTICE:

Use care when removing or installing a blade assembly. Accidental bumping can cause the arm to fall back and strike the windshield.

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 Chevrolet Warranty booklet for details.

CAUTION:

Poorly maintained and improperly used tires are dangerous. D 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.

CAUTION: (Continued)

CAUTION: (Continued)

D 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.

D 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.

D Worn, old tires can cause accidents. If your

tread is badly worn, or if your tires have been damaged, replace them.

6-40

Extended Mobility Tires (Except ZO6 Models) 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 Chevrolet or Goodyear EMT servicing facility for inspection and repair or replacement. To locate the nearest Chevrolet or Goodyear EMT servicing facility, call Roadside Assistance. For phone numbers and Roadside Assistance details, see “Roadside Assistance” or “Canadian Roadside Assistance” in the Index. You may also contact Goodyear, for the nearest authorized EMT servicing facility, by calling 1-800-789-9878.

6-41

CAUTION:

NOTICE:

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 an extended mobility tire. 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” in the Index. 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.

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.

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 Corvette’s extended mobility feature. When using winter tires on your vehicle, be sure to use them on all four wheels. See “Buying New Tires” in the Index.

6-42

NOTICE: (Continued)

If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards

When to Check Check your tires once a month or more.

Inflation -- Tire Pressure The Tire-Loading Information label, which is on the rear 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: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy

NOTICE: (Continued)

6-43

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. 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” and “Driver Information Center (DIC)” in the Index.

Tire Pressure Monitor (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 operation. 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.

6-44

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 (170 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 (170 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” in the Index. The TPM will also alert you if a tire’s pressure 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” in the Index.

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” in the Index.

CAUTION:

When the LOW 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.

6-45

D The tread or sidewall is cracked, cut or snagged

deep enough to show cord or fabric. D The tire has a bump, bulge or split. D 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).

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’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: D You can see the indicators at three or more places

around the tire.

D You can see cord or fabric showing through the

tire’s rubber.

6-46

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.

If your vehicle is equipped with Extended Mobility Tires and you feel that winter tires are needed, see “Extended Mobility Tires” in the Index.

CAUTION:

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.

CAUTION:

If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle.

6-47

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 1/2) 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.

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.

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.

6-49

Wheel Replacement Replace any wheel that is bent, cracked, or badly rusted or corroded. If wheel nuts keep coming loose, the wheel, wheel bolts and wheel nuts should be replaced. If the wheel leaks air, replace it (except some aluminum wheels, which can sometimes be repaired). See your dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces. If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.

CAUTION:

Using the wrong replacement wheels, wheel bolts or wheel nuts on your vehicle can be dangerous. It could affect the braking and handling of your vehicle, make your tires lose air and make you lose control. You could have a collision in which you or others could be injured. Always use the correct wheel, wheel bolts and wheel nuts for replacement.

NOTICE:

The wrong wheel can also cause problems with bearing life, brake cooling, speedometer or odometer calibration, headlamp aim, bumper height, vehicle ground clearance and tire clearance to the body and chassis.

6-50

CAUTION:

CAUTION:

Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after a time. The wheel could come off and cause a crash. When you change a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, you can use a cloth or 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.

CAUTION:

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

NOTICE:

Improperly tightened wheel nuts can lead 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.

6-51

Used Replacement Wheels

CAUTION:

Putting a used wheel on your vehicle is dangerous. You can’t know how it’s been used or how far it’s been driven. It could fail suddenly and cause a crash. If you have to replace a wheel, use a new GM original equipment wheel.

Using the Wheel Lock Key If you have a Z06, the wheel lock key sits in a small depression in the trunk rail on the left side, underneath the carpeting. If you have a coupe or a convertible, the wheel lock key sits in a small depression in the trunk rail directly under the left rear compartment cover.

Your vehicle’s wheel lock key has a unique registration number. The registration number is printed on a card included in your lock nut package. Also on this card is lost key replacement information. This number is not recorded by GM or your dealer, so be sure not to lose this card. You will need the information if you ever lose your wheel lock key. If you or someone else is going to remove the wheels on your vehicle, make sure that the special wheel lock key is being used to remove the wheel locks.

NOTICE:

Your wheel lock key or lock nuts could be damaged if an air or impact wrench is used with this key.

6-52

Tire Chains

CAUTION:

Lifting Your Corvette

CAUTION:

Don’t use tire chains. There’s 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 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.

6-53

CAUTION:

Getting under a vehicle when it is jacked up is dangerous. If the vehicle slips off the jack, you could be badly injured or killed. Never get under a vehicle when it is supported only by a jack.

CAUTION:

Raising your vehicle with the jack improperly positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to 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: D Be sure to place a block or pad between the

jack and the vehicle.

D Make sure the jack you’re using spans

at least two crossmember ribs.

D Lift only in the areas shown in the

following pictures.

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

6-54

Lifting From the Front

Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flame 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: D Gasoline D Benzene D Naphtha D Carbon Tetrachloride D Acetone D Paint Thinner D Turpentine D Lacquer Thinner D 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: D Alcohol D Laundry Soap D Bleach D 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. Cleaning of Fabric/Carpet 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 “Appearance Care and Materials” in the Index.

6-57

Here are some cleaning tips: D Always read the instructions on the cleaner label. D Clean up stains as soon as you can -- before they set. D Carefully scrape off any excess stain. D Use a clean cloth or sponge, and change to a

clean area often. A soft brush may be used if stains are stubborn.

D If a ring forms on fabric after spot cleaning,

clean the entire area immediately or it will set.

Cleaning Coated Moldings These moldings are around the hatch opening in the rear area. D When lightly soiled, wipe with a sponge or soft

lint-free cloth dampened with water.

D When heavily soiled, use warm soapy water.

Cleaning 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. D For stubborn stains, use a leather cleaner. See your

dealer for this product.

D Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather.

D Soiled or stained leather should be cleaned

immediately. If dirt is allowed to work into the finish, it can harm the leather.

Cleaning the 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 in the windshield and even make it difficult to see through the windshield under certain conditions.

6-58

Cleaning Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish. Cleaning the Security Shade and Convenience Net Wash with warm water and mild detergent, rinse with cold water and tumble dry on low. Do not use chlorine bleach.

Care of Safety Belts Keep belts clean and dry.

CAUTION:

Do not bleach or dye safety belts. If you do, it may severely weaken them. In a crash, they might not be able to provide adequate protection. Clean safety belts only with mild soap and lukewarm water.

Cleaning 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 “Appearance Care and Materials” in the Index.

NOTICE:

Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.

6-59

Cleaning the Outside of the 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 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.

Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See “Recommended Fluids and Lubricants” in the Index.

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

then dry the panel.

D 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.

D Don’t use abrasive cleaning materials.

6-60

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, 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.

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 “Appearance Care and Materials” in the Index. 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.

6-61

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 “Appearance Care and Materials” in the Index. Your 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 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. 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.

6-62

Cleaning Your 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. For normal hand washing of the top, have your vehicle 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 and rinse well. For an occasional cleaning using GM Convertible Top Cleaner (GM Part No. 12378520) is recommended to keep your convertible top looking good. After cleaning, reseal the surface with GM Water Repellent (GM Part No. 12378519) to repel water and dirt.

To protect the convertible top: D After you wash the vehicle, make sure the top is

completely dry before you lower it.

D Don’t get any cleaner on the vehicle’s painted finish;

it could leave streaks.

D If you decide to go through an automatic car wash,

ask the manager if the equipment could damage your top.

Cleaning 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 silicon carbide tire cleaning brushes. These brushes can also damage the surface of these wheels.

6-63

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 other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.

Cleaning Tires To clean your tires, use a stiff brush with a 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 available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.

6-64

Titanium Exhaust System (Z06 Model) 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.

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on your vehicle. This damage can take two forms: blotchy, ringlet-shaped discolorations, and small irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, Chevrolet 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.

6-65

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 8th 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’ll find this label located inside the glovebox. It’s very helpful if you ever need to order parts. On this label is: D your VIN, D the model designation, D paint information and D a list of all production options and

special equipment.

Be sure that this label is not removed from the vehicle.

6-67

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” in the Index.

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. To use the accessory power plug, do the following: 1. Remove the toe-board panel by lifting up on the

latches 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.

6-68

The plug has the following three separate wires: D The orange wire connects to battery power. D The yellow wire connects to ignition power.

(Power is only available when the ignition is in ON.)

D The black wire connects to ground.

NOTICE:

When using the accessory power plug: D DO NOT splice wires directly into the vehicle electrical wire harness. If done incorrectly, splicing may cause damage to your electrical system and would not be covered by the vehicle’s warranty.

D The maximum load of any electrical

equipment should not exceed 15 amps.

NOTICE: (Continued)

NOTICE: (Continued)

D 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.

D 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.

Headlamps 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.

6-69

Windshield Wipers 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 fixed or goes away. Fuses and Circuit Breakers 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.

6-70

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.

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 lifting up on the latches 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.

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.

CAUTION:

Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, have a qualified technician do the work.

If you want to get the service information, see “Service and Owner Publications” in the Index.

“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 Record” 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.

Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll 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 dealer.

This part tells you the maintenance services you should have done and when you should schedule them. If 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. 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: D carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Tire-Loading Information label. See “Loading Your Vehicle” in the Index.

D are driven on reasonable road surfaces within legal

driving limits.

D use the recommended fuel. See “Fuel” in the Index.

Footnotes [ 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.

Scheduled Maintenance

Engine Oil Scheduled Maintenance Change engine oil and filter as indicated by the Engine Oil Life SystemR (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 vary considerably. 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.
