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 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 pounds (45 kg) in your rear area.

I NOTICE: I Your warranty does not cover parts or

components that fail because of over- loading.

Tires

We don't make tires. Your new vehicle comes 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.

Extended Mobility Tires (omoiv) If your Corvette has optional Goodyear Extended Mobility Tires (EMT’s), the tires will have “EMT” molded on the sidewalls. These tires perform so well without any air that a Low Tire Pressure Warning System (LTPWS) is used to alert you if a tire has lost pressure. A “LOWELAT TIRE” light will appear on your Driver Information Center if a tire’s inflation pressure is less than 25 psi (1 70 kPa). If the “LOWELAT TIRE” light comes on, check your tire pressures as soon as you can. See “Low Tire Pressure Warning System” in the Index for additional information. 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 distances of 50 miles (80 km) or less and at speeds of 55 mph (90 km/h) or less, there is a good chance that the tire can be repaired. The tire can operate effectively with no air pressure for up to 200 miles (320 km) at speeds up to 55 mph (90 km/h), but the tire would then have to be replaced. Also remember: When a tire is filled with air, it provides a cushion between the road and the wheel. Because you do not 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 before you’ve driven on the tire in a deflated condition. Whenever a tire has been damaged, or if you’ve driven any distance on a deflated EMT, check with a 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. See the Goodyear Extended Mobility Tire Owner’s Manual and Limited Warranty supplied with your Corvette for additional information.

205. .

Service and Appearance Care Inflation - Tire Pressure The Tire-Loading Information label which is on 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. For competitive driving or high-speed driving (over 150 mph or 240 krn/h), make sure your tires are inflated to 35 psi (240 kPa). When you end this type of driving, reduce the “cold” inflation pressures (if necessary) to those listed on the Tire-Loading Information label.

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

Bad fuel economy.

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

When to Check: Check your tires mce a month or more. Don’t forget your compact spare tire. It should be at 50 psi (420 Wa). How to Check: Use a good quality pocket-type gauge to check tire pressure. Simply looking at the tires will not tell you the pressure, =specially if you have radial tires - which may look properly inflated even if they’re underinflated. Lf your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture. Tire Rotation I’he tires on your Corvette are lirectional, asymmetrical, 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.

Unusual wear Bad handling

0 Rough ride

Needless damage from road hazards.

. . .206

0 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, yobr 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 a “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.

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 2/32 inch (1.6 mm) or less of tread remaining. You need a new tire if 0 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.

0 The tread or sidewall is cracked, cut

or snagged deep enough to show cord or fabric.

0 The tire has a bump, bulge or split.

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.)

Treadwear The treadwear grade is a comparative rating based on the wear rate of the tire when tested under controlled conditions

207. . .

Service and Appearance Care on a specified government test course. For example, a tire graded 150 would wear one and a half (1 1/2) times as well on the government course as a tire graded 100. The relative performance of tires depends upon the actual conditions of their use, however, and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics and climate. Traction - A, B, C The traction grades, from highest to iowest 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 poor traction performance. Warning: The traction grade assigned to this tire is based on braking (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 . . .208

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 buiidup and possible tire failure. These 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 General Motors performance standards and have been approved for use on General Motors vehicles. All passenger type (P Metric) tires 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 have 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 rusted. 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.

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

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:

0 Gasoline Benzene 0 Naphtha 0 Carbon Tetrachloride

Acetone

0 Paint Thinner 0 Turpentine

Lacquer Thinner

0 Nail Polish Remover

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

. . .210

Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: 0 Alcohol 0 Laundry Soap 0 Bleach

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 GM 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:

Always read the instructions on the cleaner label. Clean up stains as soon as you can - before they set. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn.

0 Use solvent-type cleaners in a

well-ventilated area only. If you use them, don’t saturate the stained area. If a ring forms after spot cleaning, clean the entire area immediately or it will set.

Using Foam-Type Cleaner on Fabric Vacuum and brush the area to remove any loose dirt. Always clean a whole trim panel or section. Mask surrounding trim along stitch or welt lines. Mix Multi-Purpose Powdered Cleaner following the directions on the container label. Use suds only and apply with a clean sponge. Don’t saturate the material. Don’t rub it roughly. As soon as you’ve cleaned the section, use a sponge to remove the suds. Rinse the section with a clean, wet sponge. Wipe off what’s left with a slightly damp paper towel or cloth.

Then dry it immediately with a blow dryer or a heat lamp.

I NOTICE: I Be careful with a hair dryer or heat

lamp. You could scorch the fabric.

Wipe with a clean cloth.

Using Solvent-Type Cleaner on Fabric First, see if you have to use solvent-type cleaner at all. Some spots and stains will clean off better with just water and mild soap. If you need to use a solvent:

Gently scrape excess soil from the trim material with a clean, dull knife or scraper. Use very little cleaner, light pressure and clean cloths (preferably cheesecloth). Cleaning should start at the outside of the stain, “feathering” toward the center. Keep changing to a clean section of the cloth. When you clean a stain from fabric, immediately dry the area with an air hose, hair dryer, or heat lamp to help prevent a cleaning ring. (See the previous NOTICE.)

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

Special Cleaning Problems Greasy or oily stains: Such as grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt.

Carefully scrape off excess stain. Follow the solvent-type instructions described earlier. Shoe polish, wax crayon, tar and asphalt will stain if left on a vehicle seat fabric. They should be removed as soon as possible. Be careful, because the cleaner will dissolve them and may cause them to spread.

211 ...

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 Speaker Covers Vacuum around a speaker cover gently, so that the speaker won’t be damaged. If something gets on one of them, follow the steps under “Using Solvent-Type Cleaner on Fabric.” Use as little solvent as you can.

Care of Safety Belts Keep belts clean and dry.

Service and Appearance Care Non-greasy stains: Such as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood. Carefully scrape off excess stain, then sponge the soiled area with cool water.

0 Things like tar, asphalt and shoe

polish will stain if you don’t get them off quickly. Use a clean cloth and solvent-type vinyl cleaner.

0 If a stain remains, follow the

foam-type instructions described earlier.

0 If an odor lingers after cleaning

vomit or urine, treat the area with a waterbaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water.

0 If needed, clean lightly with

solvent-type cleaner.

Combination stains: Such as candy, ice cream, mayonnaise, chili sauce and unknown stains. 0 Carefully scrape off excess stain, then clean with cool water and allow to dry.

0 If a stain remains, clean it with

solvent-type cleaner.

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.

. . .212

Cleaning Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap.

For stubborn stains, use a mild solution of 10% isopropyl alcohol (rubbing alchohol) and 90% water. Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. Soiled leather should be cleaned immediately. If dirt is allowed to work into finish, it can harm the leather.

Cleaning Soft-Touch Surfaces Use only mild soap and water to clean the Soft-Touch paint surfaces in your Corvette. For protection, use ArmorAll8 or equivalent.

Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel.

Glass 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. 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.

Cleaning Dulso-Coated Moldings These moldings are around the hatch opening in your Corvette’s rear area.

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 Dulso-coated molding by wiping briskly with the solvent-type cleaner described earlier. If a ring forms, repeat the

procedure over a larger area, feathering toward the center of the ring. If the ring still remains, wipe the whole molding.

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 or other material may be on the blade or windshield. Clean the outside of the windshield with GM Windshield Cleaner, Bon-Ami 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. Clean the blade by wiping vigorously with a cloth soaked in full strength windshield washer solvent. Then rinse the blade with water. Wiper blades should be checked on a regular basis and replaced when worn.

Cleaning a Removable Roof Panel Special care is necessary when cleaning, removing and/or storing the roof panel. Flush with water to remove dust and dirt, then dry the panel. Clean the panel with GM Glass Cleaner (GM Part No. 1050427) or a liquid household 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.

Do not use a glass treatment or conditioner containing ethyl alcohol or ethyl sulfate on the roof panel. These products may damage the panel.

They may not have enough durability. clearance for the undercarriage or for the extra wide rear tires on ZR-1 models. Check with the manager before using a car wash.

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 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 car washes may cause water to enter your vehicle.

Finish Care 3ccasional waxing or mild polishing of your Corvette may be necessary to -emove residue from the paint finish. You :an get GM approved cleaning products ?ram your dealer. (See “Appearance Care ind Materials” in the Index.) Your Corvette has a “basecoat/clearcoat” Jaint finish. The clearcoat gives more lepth and gloss to the colored basecoat. 4lways use waxes and polishes that are lon-abrasive and made for a >asecoat/clearcoat paint finish.

. . .214

NOTICE: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may dull the finish or leave swirl marks,

Cleaning Your Convertible Top Your convertible top should be cleaned often. If you use an automatic car wash, use one with water jets and hanging cloths. When you hand wash the top, do it in partial shade. Vacuum away any dust and other material. Use a mild soap, lukewarm water and a soft sponge. A chamois or cloth may leave lint on the top, and a brush can chafe the threads in the top fabric. Don’t use detergents, harsh cleaners, solvents or bleaching agents. When you clean the top, put one hand under it to support it. Wet the entire vehicle and wash the top evenly to avoid spots or rings. Let the soap remain on the fabric for a few minutes. When the top is really dirty, use a mild foam-type cleaner. Thoroughly rinse the entire vehicle, then let the top dry in direct sunlight.

To protect the convertible top: 0 After you wash the vehicle, make sure

the top is completely dry before you lower it.

0 Don’t get any cleaner on the vehicle’s painted finish; it could leave streaks.

0 If you decide to go through an

automatic car wash, ask the manager if the equipment could damage your top.

Cleaning and Storage of Your Hardtop The optional hardtop has the same durable finish as the painted surfaces of your Corvette. You can wash, polish and wax it. If you store the hardtop for a long time, keep it covered in a dry place. Apply silicone grease to all the weatherstrips.

Sngine Cleaning Jse care when cleaning the LT5 engine. 10 not direct water into the “V” area on he engine between the cylinder heads. NOTICE:

I Don’t use a cleaner with a strong

alkaline base. It will discolor the aluminum.

4luminum Wheels Your aluminum wheels have a protective zoating similar to the painted surface of your vehicle. Don’t use strong soaps, shemicals, chrome polish, or other abrasive cleaners on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.

I NOTICE: I Don’t use an automatic car wash that

has hard silicon carbide cleaning brushes. These brushes can take off the protective coating.

rires Your Chevrolet dealer has a GM White Sidewall Tire Cleaner. You can use a stiff )rush with the cleaner. When applying a tire dressing always take ;are to wipe off any overspray or splash from painted surfaces. Petroleum-based products may damage the paint finish.

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 eold, damp weather more frequent application may be required. (See “Recommended Fluids and Lubricants’’ in the Index.)

Foreign Material Calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, and other foreign matter can damage your vehicle’s finish if they remain on painted surfaces. Use cleaners that are marked safe for painted surfaces to remove foreign matter.

215 ...

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) D f purchase, whichever comes first.

Service and Appearance Care I NOTICE: Finish Damage Fiberglass Springs 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.

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.

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 vehicle washing system can do this for you.

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. There are three fuse centers on your vehicle. One is in the right side of your instrument panel. Turn the knob and pull the door to access the fuses.

The other two fuse blocks are in the engine compartment. One is part of the Forward Lamp wiring harness (A), and the other is part of the ECM-Engine wiring harness (B). 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 correct size. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one of the correct value. 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 size you need. Replace it as soon as you can.

Headlights The headlight wiring is protected by a circuit breaker in the switch. An electrical overload will cause the lights to go on and off, or in some cases to remain off. If this happens, have your headlight wiring checked right away.

Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. 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 windows 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.

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 to work, to do 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 checks 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 can be relied upon to use proper parts and practices.

the

Your Vehicle and Environment Proper vehicle maintenance not only keeps your vehicle in good working condition, but it 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 vehicle. To help protect our environment, and to help keep your vehicle in good condition, please maintain your vehicle properly.

How This Part is Organized The remainder of this part is divided into five sections: “Section A: Scheduled Maintenance Services’: shows what to have done, and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s

. . .230

service department or another qua service center do these jobs.

lified

If you are skilled enough to do some work on your vehicle, you will probably want to get the service information GM publishes. You will find a list of publications and how to get them in this manual. See “Service Publications” in the Index. “Section B: Owner Checks and Services’’ tells you what should be checked whenever you stop for fuel. It also explains what you can easily do to help keep your vehicle in good condition.

“Section C: Periodic Maintenance Inspections” explains important inspections that your Chevrolet dealer’s service department or another qualified service center should perform. “Section D: Recommended Fluids and Lubricants” lists some products GM recommends to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Section E: Maintenance Record” provides a place for you to record the maintenance performed on your vehicle. Whenever any maintenance is performed, be sure to write it down in this section. This will help you determine when your next maintenance should be done. In addition, it is a good idea to keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

Section A: Scheduled Maintenance Services

Using Your Maintenance Schedule This section tells you the maintenance services you should have done and when you should schedule them. Your Chevrolet dealer knows your vehicle best and wants you to be happy with it. If you go to your dealer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts. These schedules are for vehicles that: carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Tire-Loading Information label. See “Loading Your Vehicle” in the Index. are driven on reasonable road surfaces within legal driving limits. use the recommended unleaded fuel. See “Fuel” in the Index.

Selecting the Right Schedule First you’ll need to decide which of the two schedules is right for your vehicle. Here’s how to decide which schedule to follow: Schedule I Is any one of these true for your vehicle?

Most trips are less than 4 miles (6 km). Most trips are less than 10 miles (1 6 km) when outside temperatures are below freezing. The engine is at low speed most of the time (as in door-to-door delivery, or in stop-and-go traffic). You operate your vehicle in dusty areas.

If any one (or more) of these is true for your driving, follow Schedule I. Schedule I1 Follow Schedule I1 o& above conditions is true,

Maintenance Schedule L Section A: Scheduled Maintenance Services (Cont.) Explanation of Scheduled Maintenance Services Following are explanations of the services listed in Schedule I and Schedule 11. The proper fluids and lubricants to use are listed in Section D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. NOTE: To determine your engine’s displacement and code, see “Engine Identification” in the Index.

ITEM NO. SERVICE 1 Engine Oil and Filter Change* -

Always use SH or SG Energy Conserving I1 oils of proper viscosity. The engine requires a special oil meeting GM Standard GM4718M. Oils meeting this Standard may be identified as synthetic, and should also be identified as API Service SH or SG. However, not all Synthetic API Service SH oils will meet

. . .236

this GM Standard. You should look for and use only an oil that meets GM Standard GM4718M. To determine the preferred viscosity for your vehicle’s engine (e.g., SAE 5W-30 or SAE 10W-30), see “Engine Oil” in the Index. Your vehicle has an Engine Oil Life Monitor. This monitor will show you when to change the oil - usually between 3,000 miles (5 000 km) and 7,500 miles ( 12 500 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 7,500 miles (12 500 km) or 12 months without an oil change. 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.

ITEM NO.

SERVICE Remember to reset the Oil Life Monitor when the oil has been changed. For more information, see “Engine Oil Life Monitor” in the Index. Chassis Lubrication - Lubricate suspension and steering linkage. Lubricate the transmission shift linkage, and parking brake cable guides, underbody contact points and linkage. Engine Accessory Drive Belt(s) Inspection - Inspect the belt(s) for cracks, fraying, wear and proper tension. Replace as needed. (Belts can have many small cracks in individual ribs without affecting performance.) Cooling System Service* - Drain, flush and refill the system with new or approved recycled coolant conforming to GM Specification 1825M. Keep coolant at the proper mixture as specified. See “Coolant” in the

Index. This provides proper freeze and boil protection, corrosion inhibitor level and maintains proper engine operating temperature. Inspect hoses and replace if they are cracked, swollen or deteriorated. Tighten screw-type hose clamps. Clean the outside of the radiator and air conditioning condenser. Wash the pressure cap and neck. To help ensure proper operation, we recommend a pressure test of both the cooling system and the pressure cap.

5 Transmission Service - For manual transmissions, fluid doesn’t require changing. See “Periodic Maintenance Inspection.” For automatic transmissions, change both the fluid and filter every 15,000 miles (25 000 km)

if the vehicle is mainly driven under one or more of these conditions:

In heavy city traffic where the outside temperature regularly reaches 90 O F (32 O C) or higher. In hilly or mountainous terrain. Uses such as found in taxi, police car or delivery service.

If you do not use your vehicle under any of these conditions, change both the fluid and filter every 100,000 miles (1 66 000 km).

6 Spark Plug Replacement* - Replace spark plugs with the proper type. See “Replacement Parts” in the Index.

7 Spark Plug Wire Inspection*? - Inspect for burns, cracks or other damage. Check the boot fit at the coils and at the spark plugs. Replace wires as needed.
