Two labels on your vehicle show how much weight it may properly carry. The Tire-Loading Information label found on the rear edge of the driver's door tells you the proper size, speed rating and recommended inflation pressures €or the tires on your vehicle. It also gives you impartant information about the number of people that can be in your vehicle and the total weight that you can carry. This weight is called the Vehicle Capacity Weight and includes the weight of all occupants, cargo, and all nonfactory-installed options.

The other label is the Certification label, also 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 Gross Axle Weight Rating (GAWR) 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 lbs. (45 kg) in the rear area of your Corvette.

= * 280

If you put things inside your vehicle- like: suitcases, iook, packages, or mything eke-they will go as fast ais the vehicle goes. Xyou have to stop or turn quickly, or if there is a crash, they'll keep, going.

Thingslyuulput inside..your vehicle can strike. and-injure people in a sudden-stop or twn, or in a crash.

Put things in the rear area of your vehicle. Try to spread the weight evenly. Never stack heavier things, like suitcases, inside the vehicle so that some of them are above the tops of the seats. When you carry something inside the vehicle, secure it whenever you can. Don't leave a seat folded down unless you need to.

Tires

We don't make tires. your new vehicle c o w s with high quality tires made by a leading tire manufacturer. These tires are warranted by the tire manufacturers and their warranties are delivered with every new Corvette. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.

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 a mile. If you have to check tires when they’re not cold, add 4 psi (28 kPa) to the numbers on the sticker.

Tire Rotation The tires on your Corvette are directional, asymmetrical, and are different sizes front tu rear. Due to this, your tires should not be rotated. Each tire and wheel should be used only in theqosition it is in.

When to Check: Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 1tPa). How to Check: Use the tire pressure gage provided in your center storage console to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires-which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture.

Sewice & Appearance Care

.: ;.- -

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

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%2 inch (1.6 mm) or less of tread remaining. You need a new tire if: * You can see the indicators at three places around the tire. You can see cord or fabric showing through the tire’s rubber. The tread or sidewall is cracked, cut or snagggd 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 he 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 Per€omance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that s m e 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 Spec number will be followed by an “MS” (for mud and snow).

Unijiim Tire Quality Grading The following information relates to the system developed by the United States National Highway Tr&c Safety Administration which grades tires by treadwear, traction and temperature performance. (This applies only to vehicles sold in the United States.)

Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire wh

Service & Appearance Care

Tra~ti~n-A, 6, C 33% traction grades, from highest to .lowest are: A, B, and C. 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 podr.traction p-erformance. Warning: The traction grade assigned to. this tire is based on braking (straight- ahead) traction tests and does not include cornering (turning) traction.

...

186.

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 inaterid af the tire to degenwate.-and reduce tire @e, and excessive temperature can lead to. sudden tire failure. The-grade C corresponds t o . a level of performance which d l passenger car tires must meet under:the Federal Motor Vehicle Sa€ety Standard NO.. 109. Grades B.and A represent higher levels of perfomnance on the laboratory test wheel than the minimum required by law.

Warning: The temperatute grade for this tire 'is established for a tire that is properly inftated and not overloaded. Excessive speed, underinflation, or excessive loading, iither separately or in combination, cah cause heat buildup and possible tire failure. Those grades are molded on the sidewalls of passenger car tires. While the tires available as standard or optional equipment on General Motors vehicles may vary with. respect to these grades, all such tires meet Gene$d. Motors performance standards and have been appToved for use QII General Motors vehicles. All passenger type (P Metric) tifes .must conform to federal safety requirements in addition to these. grades.

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. In most cases, you will'not need to ha\ your wheels aligned again. 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 ruste-d. If wheel nuts keep coming loose, the wheel, wheel bolts, and wheel nuts should be replaced. If the wheel leaks air out, 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 lund 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.

Automatic Vehicle Washes

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 lulcwarm 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 (non-detergent) soaps. Don’t use cleaning agents 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 a 100% cotton towel to avoid surface scratches and water spotting. High pressure vehicle washes may cause water to enter your vehicle.

c

Cleaning Your Removable Roof Panel If your Corvette is equipped with the transparent removable -roof panel option, the panel is made of acrylic plastic with a special hard coat to help resist abrasion. Special care is necessary when cleaning, removing and/or storing the roof panel.

Flush off dust and dirt with water, then dry the panel. Clean the panel with GM Glass Cleaner. Leave the cleaner on the pard for one minute, then h p e the panel with a soft, lint-free cloth. Don't use abrasive cleaning ..materials.

Cleaning Your Convertible Top Hand washing your Corvette's convertible t.op is highly recommended and the most preferred-method of cleaning. Although most automatic vehicle washes will not harm the top's fabric, vehicle washes mtith water jets and hanging cloths are preferred to those using heavy barrel brushes. Carefully vacuuming the convertible top before washing will help rem'ove excess dust and other foreign particlesi Wash the vehicle in partial shade rather than direct sunlight. U-se a sponge to wet the entire vihicle with a 1uluiwa-m mild soap solution. Using a- chamois or cloth will leave lint -on the top and using a brush may abrade the threads in the top's material. Wash the top uniformly to avoid spots or rings. Let the soap solution remain on fabric fur two to five minutes.

Maintenance Schedule Introduction

A Word About Maintenance We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may .drive it errands or in many other ways. Because of all the different ways people use their GM vehicles, maintenance needs vary. You may even need more frequent che~ks and replacements than you will find in the schedules in this part. So please read this part and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your Chevrolet dealer, the place many GM owners choose to have their maintenance work done. Your dealer c q be relied upon to use proper parts and practices.

to work, to do

Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good woxking condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance or the removal of important components can significantly affect the quality of the air we breathe. Improper fluid levels or even the wrong tire inflation can increase the level of emissions from your vehicIe. To help protect our environment, and to help keep your vehicle in good condition, please maintain your vehicle. properly.
