underhood electric fan.

In order to avoid possible contact of the hood to the headlamp doors, care should be taken in raising the hood with the headlamps up, or shut off the lamps prior to opening the hood.

Things that burn can get on hot engine parts and start a fire. These include liquids like gasoline, oil, coolant, brake fluid, windshield washer and other fluids, and plastic or rubber. You or others could be burned. Be careful not to drop or spill things that will burn onto a hot engine.

To open the hood, first pull the handle inside

Then go to the side of the vehicle and pull up on the rear edge of the hood, near the windshield.

6-9

You’ll see the following when you open the hood:

A. Coolant Surge Tank and

Pressure Cap

B. Battery C. Engine Oil Dipstick 6-10

D. Engine Oil Fill Cap E, Air Cleaner F. Power Steering Fluid Reservoir G. Brake Fluid Reservoir

H. Hydraulic Clutch Fluid Reservoir (if equipped) 1. Windshield Washer Fluid

Reservoir

Before closing the hood, be sure all the filler caps are on properly. Then, just pull the hood down and close it firmly. Engine Oil If the LOW OIL LEVEL message on the Driver Information Center comes on, it means you need to check your engine oil level right away. For more information, see “Driver Information Center” in the Index. You should check your engine oil level regularly; this is an added reminder. It’s a good idea to check your engine oil level every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground.

The engine oil dipstick is next to the coolant surge tank. The dipstick handle is a round, yellow loop.

Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.

6-11

Checking Engine Oil Pull out the dipstick and clean it with a paper towel or a cloth, then push it back in all the way. Remove it again, keeping the tip down.

When to Add Oil If the oil is at or below the ADD mark, you’ll need to add at least one quart of oil. But you must use the right kind. This part explains what kind of oil to‘use. For crankcase capacity, see “Capacities and Specifications” in the Index.

NOTICE:

Don’t add too much oil. If your engine has so much oil that the oil level gets above the upper mark that shows the proper operating range, your engine could be damaged.

6-12

The engine oil fill cap is on top of the right valve rocker arm cover.

What Kind of Oil to Use Look for two things:

GM4718M The Corvette engine requires a special oil meeting GM Standard GM47 18M. Oils meeting this Standard may be identified as synthetic. However, not all synthetic oils will meet this GM Standard. You should look for and use only an oil that meets GM Standard GM47 18M.

Be sure to fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

1 NOTICE:

If you use oils that don’t have the GM4718M Standard designation, you can cause engine damage not covered by your warranty.

6-13

RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS

FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE SAE VISCOSITY GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.

LOWEST

HOT

WEATHER

LOOK

FOR MIS SYMBOL

SAE 5W-30 As shown in the viscosity chart, SAE 5W-30 is best for your vehicle. However, you can use SAE 1OW-30 if it’s going to be 0°F (-18°C) or above. These numbers on an oil container show its viscosity, or thickness. Do not use other viscosity oils such as SAE 20W-50.

Oils meeting these requirements should also have the “Starburst” symbol on the container.

COLD WEATHER

DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED

This symbol indicates that the oil has been certified by the American Petroleum Institute (API). Do not use any oil which does not carry this Starburst symbol. You should look for this on the oil container, and use only those oils that are identified as meeting GM Standard 47 18M and have the Starburst symbol on the front of the oil container.

Your Corvette engine is filled at the factory with a Mobil l@ synthetic oil, which meets all requirements for your vehicle. Substitute Oil: When adding oil to maintain engine oil level, oil meeting GM Standard GM4718M may not be available. You can add substitute oil designated SAE 5W-30 with the “Starburst” symbol at all temperatures. If temperatures are above 0°F (- 18 O C), you may substitute SAE 1OW-30 with the “Starburst” symbol. Substitute oil not meeting GM Standard GM4718M should not be used for an oil change. Engine Oil Additives Don’t add anything to your oil. Your Chevrolet dealer is ready to advise if you think something should be added. When to Change Engine Oil Your Corvette has an Engine Oil Life Monitor. This feature will let you know when to change your oil and filter -- usually between 3,000 miles (5 000 km) and 10,000 miles (1 6 000 km) since your last oil change. Under severe conditions, the indicator may come on before 3,000 miles (5 000 km). Never drive your vehicle more than 10,000 miles (1 6 000 km) or 12 months (whichever occurs first) without an oil change. Use engine oil meeting the GM Standard GM4718M.

The system won’t detect dust in the oil. So, if you drive in a dusty area, be sure to change your oil every 3,000 miles (5 000 km) or sooner if the CHANGE OIL light comes on. Remember to reset the Engine Oil Life Monitor when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index. When Changing the Engine Oil There is a special procedure for changing engine oil. Contact your Chevrolet dealer for additional information or the procedure can be found in a Corvette Service Manual. To purchase a service manual, see “Service and Owner Publications” in the Index. How to Reset the Engine Oil Life Monitor Press RESET to acknowledge the CHANGE OIL SOON warning. The oil page on the DIC will then show a message such as OIL LIFE 0%. To reset the monitor, press and hold RESET for two seconds. You will then receive a message such as OIL LIFE 99%.

Air Cleaner

Refer to the Maintenance Schedule to determine when to replace the air filter. See “Scheduled Maintenance Services” in the Index.

What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your slun and nails with soap and water, or a good hand cleaner. Wash or throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help.

6-16

‘ A CAUTION:

- -

Air Filter Replacement To remove the air filter:

Operating the engine with the air cleaner off can cause you or others to be burned. The air cleaner not only cleans the air, it stops flame if the engine backfires. If it isn’t there, and the engine backfires, you could be burned. Don’t drive with it off, and be careful working on the engine with the air cleaner off.

NOTICE:

If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.

1. Pull up on the clips on each side to release

the assembly.

Automatic Transmission Fluid How to Check Because this operation is difficult, you may choose to have this done at your Chevrolet dealer service department. 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 Chevrolet dealer service department and have it repaired as soon as possible. There is a special procedure for checking and changing the transmission fluid, Contact your Chevrolet dealer for additional information or the procedure can be found in a Corvette Service Manual. To purchase a service manual, see “Service and Owner Publications” in the Index.

NOTICE:

We recommend that only fluid labeled DEXR0N’-I11 be used, because fluid with that label is made specially for your automatic transmission. Damage caused by fluid other than DEXRON@-I11 is not covered by your new vehicle warranty.

2. Pull the assembly out. 3. Replace the filter. 4. Push the assembly back into place. 5. Fasten the clips.

Change both the fluid and filter every 50,000 miles (80 000 km) if the vehicle is mainly driven under one of these conditions:

In heavy city traffic where the outside temperature regularly reaches 90” F (32” C) or higher. In hilly or mountainous terrain.

0 High performance operation. If you do not use your vehicle under one of these conditions, the fluid and filter do not require changing. See “Scheduled Maintenance Services” in the Index for the proper service intervals for the transmission fluid and filter. 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.

I 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. Be sure to 1 get an accurate reading if you check your transmission fluid.

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.

6-19

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.

6-20

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 Ib-ft. (27 N-m). Hydraulic Clutch The 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

How To Check and Add Fluid The clutch master cylinder is on the driver’s side of the engine compartment, near the fender. To check the fluid, remove the cap and rubber seal.

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.

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. Replace the rubber seal and cap.

6-21

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

What to Use To add lubricant when the level is low, use Axle Lubricant (GM Part No. 12345977) or SAE 8OW-90 GL-5 gear lubricant. To completely refill after draining, add 4 ounces (1 18 ml) of Limited-Slip Differential Lubricant Additive (GM Part No. 1052358). Then fill to the bottom of the filler plug hole with Axle Lubricant (GM Part No. 12345977) or SAE 8OW-90 GL-5 gear lubricant. Engine Coolant The cooling s stem in your vehicle is filled with DEX-COOL 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-COOL6 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.

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.

6-22

A 50/50 mixture of water and DEX-COOL@ coolant will:

Give freezing protection down to -34°F (-37°C). Give boiling protection up to 265 "F (129" C). Protect against rust and corrosion. Help keep the proper engine temperature, Let the warning lights and gages work as they should.

NOTICE:

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

What to Use Use a mixture of one-half clean water (preferably distilled) and one-half DEX-COOL' coolant which won't damage aluminum parts. If you use this mixture, you don't need to add anything else.

Adding only plain water to your cooling system can be dangerous. Plain water, or some other liquid like alcohol, can boil before the proper coolant mix will. Your vehicle's coolant warning system is set for the proper coolant mix. With plain water or the wrong mix, 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 mix of clean water and DEX-COOL@ coolant.

6-23

Checking Coolant

The coolant surge tank is in the engine compartment behind the headlamp on the passenger’s side.

NOTICE:

If you use an improper coolant mix, your engine could overheat and be badly damaged. The repair cost wouldn’t be covered by your warranty. Too much water in the mix 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

A CAUTION: -

Adding Coolant If you need more coolant, add the proper DEX-COOL@ coolant mixture at the surge tank, but only when the

I- ~ lbrning 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.

engine is cool. A CAUTION:

Never turn the surge tank pressure cap -- even a little -- when the engine and radiator are hot.

When your engine is cold,, the coolant level should be at the FULL COLD mark. Don’t overfill the surge tank. Too much coolant can result in an overflow when the fluid is hot. If the LOW COOLANT message comes on, it means you’re low on engine coolant.

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.

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

6-25

Surge Tank Pressure Cap

Power Steering Fluid

NOTICE:

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.

When you replace the surge tank pressure cap, a GM cap is recommended. Thermostat Engine coolant temperature is controlled by a thermostat in the engine coolant system. The thermostat stops the flow of coolant through the radiator until the coolant reaches a pre-set temperature. When you replace the thermostat, a GM thermostat is recommended.

6-26

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.

How To Check Power Steering Fluid When the engine compartment is cool, 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.

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. 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.

When the engine compartment is hot, the level should be at the HOT mark. When the engine compartment is cool, the level should be at the FULL COLD mark.

Adding Washer Fluid

NOTICE:

When using concentrated washer fluid, follow the manufacturer’s instructions for adding water.

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

0 Don’t use radiator antifreeze in your

windshield washer. It can damage your washer system and paint.

Open the cap labeled WASHER FLUID ONLY. Add washer fluid until the tank is full.

Brakes Brake Fluid

Your brake master cylinder reservoir is here. It is filled with DOT-3 brake fluid. 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.

A 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.

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 -- such as Delco Supreme ll@ (GM Part No. 12377967). Use new brake fluid from a sealed container only. 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.

NOTICE:

0 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.

0 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.

With the wrong kind of fluid in your b,,ke 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. 6-30

Brake Wear Your Corvette 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).

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. Brake Adjustment As you make brake stops, your disc brakes automatically adjust for wear.

6-31

Replacing Brake System Parts The braking system on a modern 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 have to have 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. Battery Every new Corvette has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom battery. Get one that has the replacement number shown on the original battery’s label. For battery replacement, see your dealer or the Corvette Service Manual. To purchase a service manual, see “Service and Owner Publications” in the Index. After the battery has been replaced, refer to the

6-32

“Remote Function Actuation System” in the Index to resynchronize your transmitter(s). Vehicle Storage If you’re not going to drive your vehicle for 25 days or more, take off the black, negative (-) cable from the battery. This will help keep your battery from running down.

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. Halogen Bulbs

HeadlampsLHighbeam 1. The headlamps need to be halfway open. Turn the

headlamp switch on, then quickly back to the parking lamps setting. You may have to do this a few times to get the half-open position.

Tires Your new Corvette 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 Corvette Warranty booklet for details.

Poorly maintained and improperly used tires are dangerous. 0 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)

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. 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.

-- Tire Pressure” in this section

See “Inflation the correct inflation pressure for competitive or high-speed driving.

Extended Mobility Tires Your Corvette, 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. 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.

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 P a ) and 25 psi (170 Wa). 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 Wa). 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.

6-41

I 9 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.

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 k d 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. Call Chevrolet at 1-800-CHEV-USA (1-800-243-8872) or Goodyear at 1-800-789-9878 24-hours a day for information on the location of the nearest EMT servicing facility. In Canada, contact the Customer Communication Center at 1-800-263-3777, or Canadian Roadside Assistance at 1-800-268-6800. You can also use the Goodyear number listed above to locate an authorized EMT servicing facility.

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).

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.

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 fi-om an authorized Goodyear EMT retailer. These tires will improve snow traction while maintaining your Corvette’s extended mobility feature. See the Goodyear Extended Mobility Tire Owner’s Manual and Limited Warranty supplied with your Corvette for additional information.

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. Tire Rotation The tires on your Corvette are directional and 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.

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: 0 Too much flexing 0 Too much heat 0 Tire overloading 0 Bad wear

Bad handling

0 Bad fuel economy. If your tires have too much air (overinflation), you can get the following:

Unusual wear 0 Bad handling

Rough ride

0 Needless damage from road hazards.

6-44

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).

6-45

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.

I \ CAJTION:

Mixing tires could cause you to lose control while driving. If you mix tires of different sizes (other than those originally installed on your Corvette) 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 Corvette) may also cause damage to your vehicle. Be sure to use the correct size and type tires on all four wheels.

If you feel that winter tires are needed, see “Extended Mobility Tires” in the Index.

Uniform Tire Quality Grading 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. Tkaction -- A, B, C The traction grades, from highest to lowest, are A, B, and C, and they 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 bralung (straight ahead) traction tests and does not include cornering (turning) traction.

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.

6-47

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 Chevrolet 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 Corvette.

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.

A CAUTION:

A CAUTION:

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

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

NOTICE:

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

If you

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.

6-49

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 an accident. If you have to replace a wheel, use a new GM original equipment wheel.

Using the Wheel Lock Key The wheel lock key sits in a small depression in the trunk rail directly under the left-hand rear compartment cover. Your vehicle 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.

6-50

If you or someone else is going to remove the wheels on your vehicle, make sure that the special wheel nut socket and wheel lock key are being used.

NOTICE:

Your wheels could be damaged if the wheel nut socket is not used to remove your vehicle’s wheels.

The wheel nut socket can be used with an air wrench or a torque wrench. The wheel lock key can be used with a torque wrench, but not with an air or impact wrench.

NOTICE:

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

Tire Chains

NOTICE:

Don’t use tire chains. They can damage your vehicle because there’s not enough clearance. 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.

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 Corvette, 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 Naphtha Carbon Tetrachloride Acetone Paint Thinner Turpentine Lacquer Thinner Nail Polish Remover

They can all be hazardous -- some more than others -- and they can all damage your vehicle, too.

6-51

Don't use any of these unless this manual says you can. In many uses, these will damage your vehicle:

5. If a ring forms after spot cleaning, clean the entire

area immediately or it will set.

Alcohol Laundry Soap Bleach Reducing Agents

Cleaning the Inside of Your Corvette Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your Chevrolet dealer has two cleaners, a solvent-type spot lifter and a foam-type powdered cleaner. They will clean normal spots and stains very well. Do not use them on vinyl or leather. Here are some cleaning tips: 1. Always read the instructions on the cleaner label. 2. Clean up stains as soon as you can -- before they set. 3. Use a clean cloth or sponge, and change to a

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

4. Use solvent-type cleaners in a well-ventilated area

only. If you use them, don't saturate the stained area.

Fabric Protection Your Corvette has carpet that has been treated with Scotchgard" Fabric Protector, a 3M product. It protects fabrics by repelling oil and water, which are the carriers of most stains. Even with this protection, you still need to clean your carpet often to keep it looking new. Further information on cleaning is available by calling 1-800-433-3296 (in Minnesota, 1-800-642-6167). Cleaning Vinyl Use warm water and a clean cloth. 0 Rub with a clean, damp cloth to remove dirt. You

may have to do it more than once.

0 Things like tar, asphalt and shoe polish will stain if you don't get them off quickly. Use a clean cloth and a vinyyleather cleaner. See your dealer for this product.

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. Cleaning Soft-Touch Paint Surfaces Use only mild soap and water to clean the Soft-Touch paint surfaces in your Corvette. 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.

Cleaning Coated Moldings These moldings are around the hatch opening in your Corvette’s rear area. 0 When lightly soiled, wipe with a sponge or soft

lint-free cloth dampened with water. When heavily soiled, use warm soapy water.

You can remove scratches from a coated molding by wiping briskly with the solvent-type cleaner described earlier. If a ring forms, repeat the procedure over a larger area, wiping toward the center of the ring. If the ring still remains, wipe the whole molding. 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. 0 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.

6-53

Care of Safety Belts Keep belts clean and dry.

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

Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner (GM Part No. 1050427) or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. 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.

Powder (non-scratching

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 GM Windshield Cleaner, Bon glass cleaning powder), GM Part No. 1050011. 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 horn 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. 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. Don’t use abrasive cleaning materials.

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

I 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 Corvette 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. Don’t use strong soaps or chemical detergents. Use liquid hand, dish or car washing (mild detergent) soaps. 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.

6-55

High pressure car washes may cause water to enter your vehicle.

L NOTICE:

Conveyor systems on some automatic car washes may damage a Corvette. They may not have enough clearance for the undercarriage or for the wide rear tires. Check with the manager before using a car wash.

Your Corvette has a “basecoatklearcoat” 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 basecoatklearcoat paint finish.

I NOTICE:

Machine compounding or aggressive polishing on a basecoatklearcoat paint finish may dull the finish or leave swirl marks.

Cleaning Exterior LampsLenses Use lukewarm or cold water, a soft cloth and a liquid hand, dish or car washing (mild detergent) soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.” Finish Care Occasional waxing or mild polishing of your Corvette 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.)

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 Corvette garaged or covered whenever possible.

6-56

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 or abrasive cleaning brushes on them because you could damage the surface. 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. 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.

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. 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.

6-57

Fiberglass Springs

I 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.

Service Parts Identification Label You’ll find this label on the cover assembly for the rear left-hand compartment storage pocket. It’s very helpful if you ever need to order parts. On this label is: 0 your VIN,

the model designation, 0 paint information and 0 a list of all production options and special

equipment.

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

Vehicle Identification Number (VIN)

This is the legal identifier for your Corvette. 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.

Electrical System Add-on Electrical Equipment

NOTICE:

Don’t add anything electrical to your Corvette 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 Corvette, see “Servicing Your Air Bag-Equipped Corvette” in the Index.

Accessory Power Plug This plug can be used to connect electrical equipment such as a cellular phone or CB radio. The accessory power plug is located at the top left corner of the passenger’s side footwell. Be sure to follow the installation instructions included with the equipment. To use the accessory power plug: 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 left top 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 three separate wires:

The orange wire connects to battery power. The yellow wire connects to ignition power. Power is only available in the ignition ON position. The black wire connects to ground.

6-61

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. 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.

NOTICE:

When using the accessory plug:

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. 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 plug and damage your electrical system and the damage would not be covered by your warranty.

6-62

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. 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 interior fuse center is on the passenger’s side of the vehicle, under the instrument panel and under the toe board.

Remove the toe board and carpet covering to access the fuse block. Then turn the fuse block door knob and pull the door to access the fuses.
