THIS VEHICLE CONFORMS TO ALL APPLI- CABLE U.S. FEDERAL MOTOR VEHICLE SAFETY, BUMPER, AND THEFT PREVENTION STANDARDS IN EFFECT ON THE DATE OF MANUFACTURE SHOWN ABOVE.

The other label is the Certification label, found on the rear edge of the driver’s door. It tells you the gross weight capacity of your vehicle, called the GVWR (Gross Vehicle Weight Rating). The GVWR includes the weight of the vehicle, all occupants, fuel and cargo. Never exceed the GVWR for your vehicle, or the GAWR (Gross Axle Weight Rating) for either the front or rear axle. And, if you do have a heavy load, you should spread it out. Don’t carry more than 100 pounds (45 kg) in your rear area.

' A CA"T1ON:

Do not load your vehicle any heavier than the GVWR, or either the maximum front or rear GAWR. If you do, parts on your vehicle can break, or it can change the way your vehicle handles. These could cause you to lose control. Also, overloading can shorten the life of your vehicle.

NOTICE:

Your warranty does not cover parts or components that fail because of overloading.

Jump Starting If your battery has run down, you may want to use another vehicle and some jumper cables to start your Corvette. But please use the following steps to do it safely.

NOTICE:

Ignoring these steps could result in costly damage to your vehicle that wouldn’t be covered by your warranty. Trying to start your Corvette by pushing or pulling it could damage your vehicle, even if you have a manual transmission. And if you have an automatic transmission, it won’t start that way.

Batteries can hurt you. They can be dangerous because:

They contain acid that can burn you.

0 They contain gas that can explode or ignite. 0 They contain enough electricity to

burn you.

If you don’t follow these steps exactly, some or all of these things can hurt you.

1. Check the other vehicle. It must have a 12-volt

battery with a negative ground system.

I NOTICE:

If the other system isn’t a 12-volt system with a negative ground, both vehicles can be damaged.

4. Open the hoods and locate the batteries. Find the positive (+) and negative (-) terminals on each.

A CAUTION:

An electric fan can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

2. Get the vehicles close enough so the jumper cables

can reach, but be sure the vehicles aren’t touching each other. If they are, it could cause a ground connection you don’t want. You wouldn’t be able to start your Corvette, and the bad grounding could damage the electrical systems.

3. Turn off the ignition on both vehicles. Unplug

unnecessary accessories plugged into the cigarette lighter or accessory plug. Turn off all lamps that aren’t needed as well as radios. This will avoid sparks and help save both batteries. In addition, it could save your radio!

NOTICE:

If you leave your radio on, it could be badly damaged. The repairs wouldn’t be covered by your warranty.

5-4

’ Using a match near a battery can cause battery

flashlight if

gas to explode. People have been hurt doing this, and some have been blinded. Use a you need more light. Be sure the battery has enough water. You don’t need to add water to the Delco Freedom’ battery installed in every new GM vehicle. But if a battery has filler caps, be sure the right amount of fluid is there. If it is low, add water to take care of that first. If you don’t, explosive gas could be present. Battery fluid contains acid that can burn you. Don’t get it on you. If you accidentally get it in your eyes or on your skin, flush the place with water and get medical help immediately.

5. Check that the jumper cables don’t have loose or

missing insulation. If they do, you could get a shock. The vehicles could be damaged, too. Before you connect the cables, here are some basic things you should know. Positive (+) will go to positive (+) and negative (-) will go to an unpainted metal engine part or a body metal surface. Don’t connect positive (+) to negative (-) or you will get a short that would damage the battery and maybe other parts, too. And don’t connect negative (-) to negative (-) on the dead battery, as this can cause sparks. Follow Step 9 carefully.

Fans or other moving engine parts can injure you badly. Keep your hands away from moving parts once the engine is running.

7. Don't let the other end . . Connect , \ it

touch metal. to the positive (+) terminal of the good battery. Use a remote positive (+) terminal if

8. Now connect the

black negative (-) cable to the good battery's negative (-) terminal. Don't let the other end touch anything until the next step.

6. Positive (+) goes to positive (+) and negative (-)

goes to negative (-) or a metal engine part. Connect the red positive (+) cable to the positive (+) terminal of the vehicle with the dead battery. Use a remote positive (+) terminal if the vehicle has one.

5-6

11. Try to start the vehicle with the dead battery. If it won’t start after a few tries, it probably needs service.

12. Remove the cables in reverse order to prevent

electrical shorting. Take care that they don’t touch each other or any other metal.

I - +

9. The other end of the negative (-) cable doesn’t go to the dead battery. It goes to a heavy, unpainted metal part on the engine of the vehicle with the dead battery. Attach the cable at least 18 inches (45 cm) away from the dead battery, but not near engine parts that move. The electrical connection is just as good there, but the chance of sparks getting back to the battery is much less.

10. Now start the vehicle with the good battery and run

the engine for a while.

Towing Your Vehicle Try to have a GM dealer or a professional towing service tow your vehicle. They can provide the right equipment and know how to tow your vehicle without damage. If your vehicle has been changed or modified since it was factory new by adding aftermarket items like fog lamps, aero skirting, or special tires and wheels, these instructions and illustrations may not be correct. Before you do anything, turn on the hazard warning flashers.

When you call, tell the towing service: 0 That your vehicle cannot be towed with

sling-type equipment. That your vehicle has rear-wheel drive. The make, model and year of your vehicle. 0 Whether you can still move the shift lever. 0 If there was an accident, what was damaged. 0 If the vehicle is to be towed from the rear with a wheel-lift truck, a front dolly will be required.

When the towing service arrives, let the tow operator know that this manual contains detailed towing instructions and illustrations. The operator may want to see them.

I ’ A CAUTION:

To help avoid injury to you or others:

A vehicle can fall from a car carrier if it isn’t adequately secured. This can cause a collision, serious personal injury and vehicle damage. The vehicle should be tightly secured with chains or steel cables before it is transported. Don’t use substitutes (ropes, leather straps, canvas webbing, etc.) that can be cut by sharp edges underneath the towed vehicle. Always use R-hooks inserted in the front and rear R-hook slots. Never use J-hooks. They will damage drivetrain and suspension components.

Never let passengers ride in a vehicle that is being towed. Never tow faster than safe or posted speeds. Never tow with damaged parts not fully secured. Never get under your vehicle after it has been lifted by the tow truck. Always secure the vehicle on each side with separate safety chains when towing it. Use only R-hooks.

When your vehicle is being towed, have the ignition key in the OFF position. The steering wheel should be clamped in a straight-ahead position, with a clamping device designed for towing service. Do not use the vehicle’s steering column lock for this. The transmission should be in NEUTRAL (N) and the parking brake released.

Front Towing Tow Limits -- 35 mph (55 k d ) , 50 miles (80 km)

NOTICE:

Do not tow with sling type equipment or bumper, fog lamps and air dam damage will occur. Use wheel-lift or car-carrier equipment. Additional ramping may be required for car-carrier equipment. Use safety chains and wheel straps. Use the shipping slots for car-carrier securing. Don’t have your vehicle towed on the rear wheels unless you have to. If the vehicle must be towed on the rear wheels, don’t exceed the tow limits or your transmission will be damaged. Towing a vehicle over rough surfaces could damage the vehicle. Damage can occur from vehicle to ground or vehicle to wheel-lift equipment. To help avoid damage, install a towing dolly and raise the vehicle until adequate clearance is obtained between the ground and/or wheel-lift equipment.

Engine Overheating You will find an engine coolant temperature gage on the instrument cluster and a COOLANT OVER TEMP message on the Driver Information Center. Overheated Engine Protection Operating Mode Should a low coolant condition exist and the messages COOLANT OVERTEMP and REDUCED ENGINE POWER are displayed, along with the CHECK ENGINE light, an overheat protection mode which alternates firing groups of four cylinders helps prevent engine damage. In this mode, you will notice a loss in power and engine performance. This operating mode allows your vehicle to be driven to a safe place in an emergency; you may drive up to 50 miles (80 km).

NOTICE:

After driving in the overheated engine protection operating mode, to avoid engine damage, allow the engine to cool before attempting any repair. The engine oil will be severely degraded. Repair the cause of coolant loss, change the oil and reset the oil life monitor. See “Engine Oil, When to Change” in the Index.

5-13

If Steam Is Coming From Your Engine

A A

’ L

F-J

’ \

5-14

Steam from an overheated engine can burn you badly, even if you just open the hood. Stay away from the engine if you see or hear steam coming from it. Just turn it off and get everyone away from the vehicle until it cools down. Wait until there is no sign of steam or coolant before you open the hood. If you keep driving when your engine is overheated, the liquids in it can catch fire. You or others could be badly burned. Stop your engine if it overheats, and get out of the vehicle until the engine is cool.

NOTICE:

If your engine catches fire because you keep driving with no coolant, your vehicle can be badly damaged. The costly repairs would not be covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index.

If No Steam Is Coming From Your Engine If you get the overheat warning but see or hear no steam, the problem may not be too serious. Sometimes the engine can get a little too hot when you:

Climb a long hill on a hot day. Stop after high-speed driving. 0 Idle for long periods in traffic. If you get the overheat warning with no sign of steam, try this for a minute or so: 1. 2.

Turn off your air conditioner. Turn on your heater to full hot at the highest fan speed and open the window as necessary. If you’re in a traffic jam, shift to NEUTRAL (N); otherwise, shift to the highest gear while driving -- AUTOMATIC OVERDRIVE (@) or DRIVE (D) for automatic transmissions.

3.

If you no longer have the overheat warning, you can drive. Just to be safe, drive slower for about 10 minutes. If the warning doesn’t come back on, you can drive normally. If the warning continues, pull over, stop, and park your vehicle right away. If there’s still no sign of steam, you can idle the engine for two or three minutes while you’re parked, to see if the warning stops. But then, if you still have the warning, turn ofthe engine and get everyone out of the vehicle until it cools down. Also, see “Overheated Engine Protection Operating Mode” listed previously in this section. You may decide not to lift the hood but to get service help right away.

5-15

Cooling System When you decide it’s safe to lift the hood, here’s what you’ll see:

A CAUTION:

An electric fan under the hood can start up even when the engine is not running and can injure you. Keep hands, clothing and tools away from any underhood electric fan.

If the coolant inside the coolant surge tank is boiling, don’t do anything else until it cools down.

A. Electric Engine Fans B. Coolant Surge Tank

The coolant level should be at or above the FULL COLD mark. If it isn’t, you may have a leak in the radiator hoses, heater hoses, radiator, water pump or somewhere else in the cooling system.

Heater and radiator hoses, and other engine parts, can be very hot. Don’t touch them. If you do, you can be burned. Don’t run the engine if there is a leak. If you run the engine, it could lose all coolant. That could cause an engine fire, and you could be burned. Get any leak fixed before you drive the vehicle.

1 NOTICE:

Engine damage if you keep running your engine without coolant isn’t covered by your warranty. See “Overheated Engine Protection Operating Mode” in the Index.

If there seems to be no leak, with the engine on, check to see if the electric engine fans are running. If the engine is overheating, both fans should be running. If they aren’t, your vehicle needs service.

5-17

How to Add Coolant to the Coolant Surge Tank If you haven’t found a problem yet, but the coolant level isn’t at the FULL COLD mark, add a 50/50 mixture of clean water (preferably distilled) and DEX-COOL@ coolant at the coolant surge tank, but be sure the cooling system, including the coolant surge tank pressure cap, is cool before you do it. (See “Engine Coolant” in the Index for more information.)

Steam and scalding liquids from a hot cooling system can blow out and burn you badly. They surge tank pressure cap -- even a little -- they are under pressure, and if you turn the coolant can come out at high speed. Never turn the cap when the cooling system, including the coolant surge tank pressure cap, is hot. Wait for the cooling system and coolant surge tank pressure cap to cool if you ever have to turn the pressure cap.

1 A CAUTION:

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 50150 mix of clean water and DEX-COOL@ coolant.

NOTICE:

In cold weather, water can freeze and crack the engine, radiator, heater core and other parts. So use the recommended coolant.

A CAUTIOK

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

5-19

3. Then fill the coolant surge tank with the proper mix,

up to the FULL COLD mark.

1. You can remove the coolant surge tank pressure cap when the cooling system, including the coolant surge tank pressure cap and upper radiator hose, is no longer hot. Turn the pressure cap slowly about one-quarter turn to the left and then stop. If you hear a hiss, wait for that to stop. A hiss means there is still some pressure left. Then keep turning the pressure cap slowly, and remove it.

2.

5-20

4. With the coolant surge tank pressure cap off, start the

engine and let it run until you can feel the upper radiator hose getting hot. Watch out for the engine fans. By this time, the coolant level inside the coolant surge tank may be lower. If the level is lower, add more of the proper mix to the coolant surge tank until the level reaches the FULL COLD mark.

5. Then replace the pressure cap. Be sure the pressure

cap is tight.

5-21

-I ’ A CAUTION:

If You’re Stuck: In Sand, Mud, Ice or Snow What you don’t want to do when your vehicle is stuck is to spin your wheels too fast. The method known as “rocking” can help you get out when you’re stuck, but you must use caution.

A QUTION:

If you let your tires spin at high speed, they can explode, and you or others could be injured. And, the transmission or other parts of the vehicle can overheat. That could cause an engine compartment fire or other damage. When you’re stuck, spin the wheels as little as possible. Don’t spin the wheels above 35 mph (55 km/h) as shown on the speedometer.

If a Tire Goes Flat Your Corvette has neither a spare tire nor tire changing equipment, because it was built with Goodyear Extended Mobility Tires (EMT). See “Extended Mobility Tires” in the Index.

Because your vehicle has no spare tire, no tire changing equipment, and no provisions to store a tire in the vehicle, special tools and procedures are required if a tire needs to be serviced. If these tools and procedures aren’t used, you or others could be injured and your vehicle could be damaged. Always be sure the proper tools and procedures, as described in the Corvette Service Manual, are used.

To order a service manual, see “Service and Owner Publications” in the Index.

5-22

NOTICE:

Spinning your wheels can destroy parts of your vehicle as well as the tires. If you spin the wheels too fast while shifting your transmission back and forth, you can destroy your transmission.

For information about using tire chains on your vehicle, see “Tire Chains” in the Index.

Rocking Your Vehicle To Get It Out First, turn your steering wheel left and right. That will clear the area around your front wheels. You should turn your TCS off. (See “Traction Control System” in the Index.) Then shift back and forth between REVERSE (R) and a forward gear, spinning the wheels as little as possible. For a manual transmission, shift slowly between either FIRST (1) or SECOND (2) and REVERSE (R), allowing the wheels to stop before shifting into gear. Release the accelerator pedal while you shift, and press lightly on the accelerator pedal when the transmission is in gear. If that doesn’t get you out after a few tries, you may need to be towed out. If you do need to be towed out, see “Towing Your Vehicle” in the Index.

Doing Your Own Service Work If you want to do some of your own service work, you’ll want to get the proper Corvette Service Manual. It tells you much more about how to service your Corvette than this manual can. To order the proper service manual, see “Service and Owner Publications” in the Index. Your vehicle has an air bag system. Before attempting to do your own service work, see “Servicing Your Air Bag-Equipped Corvette” in the Index. You should keep a record with all parts receipts and list the mileage and the date of any service work you perform. See “Maintenance Record” in the Index.

6-2

c You can be injured and your vehicle could be damaged if you try to do service work on a vehicle without knowing enough about it. Be sure you have sufficient knowledge, experience, the proper replacement parts and tools before you attempt any vehicle maintenance task. Be sure to use the proper nuts, bolts and other fasteners. “English” and “metric” fasteners can be easily confused. If you use the wrong fasteners, parts can later break or fall off. You could be hurt.

Adding Equipment to the Outside of Your Vehicle Things you might add to the outside of your vehicle can affect the aifflow around it. This may cause wind noise and affect windshield washer performance. Check with your Chevrolet dealer before adding equipment to the outside of your vehicle.

Fuel Use premium unleaded gasoline rated at 91 octane or higher for best performance. You may use middle grade or regular unleaded gasolines, but your vehicle may not accelerate as well. At a minimum, the gasoline you use should meet specifications ASTM D48 14 in the United States and CGSB 3.5-M93 in Canada. Improved gasoline specifications have been developed by the American Automobile Manufacturers Association (AAMA) for better vehicle performance and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and emission control system protection compared to other gasolines. Be sure the posted octane for premium is at least 91 (at least 89 for middle grade and 87 for regular). If the octane is less than 87, you may get a heavy knocking noise when you drive. If it’s bad enough, it can damage your engine.

6-3

If you’re using fuel rated at the recommended octane or higher and you hear heavy knocking, your engine needs service. But don’t worry if you hear a little pinging noise when you’re accelerating or driving up a hill. That’s normal, and you don’t have to buy a higher octane fuel to get rid of pinging. It’s the heavy, constant knock that means you have a problem. If your vehicle is certified to meet California Emission Standards (indicated on the underhood emission control label), it is designed to operate on fuels that meet California specifications. If such fuels are not available in states adopting California emissions standards, your vehicle will operate satisfactorily on fuels meeting federal specifications, but emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on and/or your vehicle may fail a smog-check test. If this occurs, return to your authorized Chevrolet dealer for diagnosis to determine the cause of failure. In the event it is determined that the cause of the condition is the type of fuels used, repairs may not be covered by your warranty. Some gasolines that are not reformulated for low emissions contain an octane-enhancing additive called methylcyclopentadienyl manganese tricarbonyl (MMT); ask your service station operator whether or not his fuel contains MMT. General Motors does not recommend the use of such gasolines. If fuels containing MMT are used, 6-4

spark plug life may be reduced and your emission control system performance may be affected. The malfunction indicator lamp on your instrument panel may turn on. If this occurs, return to your authorized Chevrolet dealer for service. To provide cleaner air, all gasolines in the United States are now required to contain additives that will help prevent deposits from forming in your engine and fuel system, allowing your emission control system to function properly. Therefore, you should not have to add anything to the fuel. In addition, gasolines containing oxygenates, such as ethers and ethanol, and reformulated gasolines may be available in your area to help clean the air. General Motors recommends that you use these gasolines if they comply with the specifications described earlier.

NOTICE:

Your vehicle was not designed for fuel that I contains methanol. Don’t use it. It can corrode metal parts in your fuel system and also damage I plastic and rubber parts. That damage wouldn’t 1 be covered under your warranty.

Fuels in Foreign Countries If you plan on driving in another country outside the United States or Canada, the proper fuel may be hard to find. Never use leaded gasoline or any other fuel not recommended in the previous text on fuel. Costly repairs caused by use of improper fuel wouldn’t be covered by your warranty. To check on fuel availability, ask an auto club, or contact a major oil company that does business in the country where you’ll be driving. You can also write us at the following address for advice. Just tell us where you’re going and give your Vehicle Identification Number (VIN).

Filling Your Tank

The fuel fill door is on the driver’s side of the vehicle. The fuel cap is attached by a tether for your convenience.

Gasoline vapor is highly flammable. It burns violently, and that can cause very bad injuries. Don’t smoke if you’re near gasoline or refueling your vehicle. Keep sparks, flames and smoking materials away from gasoline.

6-5

The fuel fill door release is located at the right front corner of the center console storage compartment.

I-

If your fuel filler door release won’t operate, there is a manual release tab. The tab is located against the upper trim on the driver’s side in the rear compartment. 6-6

When you put the cap back on, turn it to the right (clockwise) until you hear a clicking sound. Make sure you fully install the cap.

NOTICE:

If you need a new cap, be sure to get the right type. Your dealer can get one for you. If you get the wrong type, it may not fit or have proper venting, and your fuel tank and emissions system might be damaged.

If you get gasoline on yourself and then something ignites it, you could be badly burned. Gasoline can spray out on you if you open the fuel filler cap too quickly. This spray can happen if your tank is nearly full, and is more likely in hot weather. Open the fuel filler cap slowly and wait for any “hiss” noise to stop. Then unscrew the cap all the way.

Be careful not to spill gasoline. Clean gasoline from painted surfaces as soon as possible. See “Cleaning the Outside of Your Corvette” in the Index.

6-7

Checking Things Under the Hood

Hood Release

NOTICE:

An electric fan under the hood can start up and injure you even when the engine is not running. Keep hands, clothing and tools away from any 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.

6-8

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

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.

6-43

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.

When It’s Time for New Tires

One way to tell when it’s time for new tires is to check the treadwear indicators, which will appear when your tires have only 1/16 inch (1.6 mm) or less of tread remaining.

You need a new tire if any of the following statements are true:

You can see the indicators at three or more places around the tire. You can see cord or fabric showing through the tire’s rubber.

The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric. The tire has a bump, bulge or split. The tire has a puncture, cut or other damage that can’t be repaired well because of the size or location of the damage.

Buying New Tires To find out what kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way your vehicle will continue to have tires that are designed to give proper endurance, handling, speed rating, traction, ride and other things during normal service on your vehicle. If your tires have an all-season tread design, the TPC number will be followed by an “MS” (for mud and snow).

If you ever replace your tires with those not having a TPC Spec number, make sure they are the same size, load range, speed rating and construction type (bias, bias-belted or radial) as your original tires.

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.

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.
