conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have poor traction performance. Warning: The traction grade assigned to this tire is based on straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.


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 dealer if any of these conditions exist. Your dealer will know the kind of wheel you need. Each new wheel should have the same load-carrying capacity, diameter, width, offset and be mounted the same way as the one it replaces.


If you need to replace any of your wheels, wheel bolts or wheel nuts, replace them only with new GM original equipment parts. This way, you will be sure to have the right wheel, wheel bolts and wheel nuts for your vehicle.


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 or tire chain clearance to the body and chassis. See Changing a Flat Tire on page 5-71 for more information.

If a Tire Goes Flat It’s unusual for a tire to “blow out” while you’re driving, especially if you maintain your tires properly. If air goes out of a tire, it’s much more likely to leak out slowly. But if you should ever have a “blowout”, here are a few tips about what to expect and what to do: If a front tire fails, the flat tire will create a drag that pulls the vehicle toward that side. Take your foot off the accelerator pedal and grip the steering wheel firmly. Steer to maintain lane position, and then gently brake to a stop well out of the traffic lane. A rear blowout, particularly on a curve, acts much like a skid and may require the same correction you’d use in a skid. In any rear blowout, remove your foot from the accelerator pedal. Get the vehicle under control by steering the way you want the vehicle to go. It may be very bumpy and noisy, but you can still steer. Gently brake to a stop - well off the road if possible. If a tire goes flat, the next part shows how to use your jacking equipment to change a flat tire safely.


Used Replacement Wheels


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


Tire Chains Notice: Use tire chains only where legal and only when you must. Use only SAE Class ”S” type chains that are the proper size for your tires. Install them on the rear axle tires and tighten them as tightly as possible with the ends securely fastened. Drive slowly and follow the chain manufacturer’s instructions. If you can hear the chains contacting your vehicle, stop and retighten them. If the contact continues, slow down until it stops. Driving too fast or spinning the wheels with chains on will damage your vehicle.


5-70


Changing a Flat Tire


If a tire goes flat, avoid further tire and wheel damage by driving slowly to a level place. Turn on your hazard warning flashers.


Changing a tire can cause an injury. The vehicle can slip off the jack and roll over you or other people. You and they could be badly injured. Find a level place to change your tire. To help prevent the vehicle from moving:


1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine. 4. Put the wheel blocks at the front and rear


of the tire farthest away from the one being changed. That would be the tire on the other side of the vehicle, at the opposite end.


The following steps will tell you how to use the jack and change a tire.


5-7 1


Removing the Spare Tire and Tools


The jacking equipment you’ll need is stored by your vehicle’s rear doors, along the passenger’s side wall.


1. Remove the jack cover by pulling it away from


the side wall and down to release the tabs securing the top of the cover.


2. Remove the wheel blocks by turning the top nut counterclockwise. Remove the nut and washer, then pull the wheel blocks off the bolt.


3. Push down on the bolt and remove the hooked end from the slot. Slide the jack toward the front of the vehicle and lift it from the mounting. Remove the extension and the ratchet from the pouch.


5-72


Your compact spare tire is stored underneath the rear of your vehicle. You will use the ratchet and extension to lower the compact spare tire.


The ratchet has an UP side.


It also has a DOWN side.


5-73


4. Attach the ratchet to the extension, with the DOWN


side facing you. The extension has a socket end and a flat chisel end.


5. Put the flat end of the extension on an angle through


the hole in the rear door frame, above the bumper. Be sure the flat end connects into the hoist shaft.


7. When the tire has


been lowered, tilt the retainer plate at the end of the cable and pull it through the wheel opening.


8. Pull the tire out from under the vehicle. Notice: To help avoid vehicle damage, do not drive the vehicle before the cable is restored.


6. Turn the ratchet counterclockwise to lower the compact spare tire to the ground. Keep turning the ratchet until the spare tire can be pulled out from under the vehicle.


5-74


B


The tools you’ll be using include the jack (A), wheel blocks (B), extension (C) and ratchet (D).


Removing the Wheel Covers YOU will have to take off the hub caps to reach the wheel nuts.


To remove the hub cap from the aluminum wheel, fit the flat end of the extension into the notch. Then, remove the center cap.


5-75


Removing the Flat Tire and Installing the Spare Tire 1 . Before you start, block the front and rear of the tire farthest away from the one being changed. Then put your c o r - x t spare tire near the flat tire.


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

Ra.,.ng positioned can damage the vehicle and even make the vehicle fall. To help avoid personal injury and vehicle damage, be sure to fit the jack lift head into the proper location before raising the vehicle.


5-76


2. With the DOWN side facing you, turn the


ratchet and socket to loosen all the wheel nuts counterclockwise. Don’t remove them yet.


3. The jack has a bolt on the end. Attach the socket


end of the extension to the jack bolt.


4. Attach the ratchet to the extension with the UP side


facing you.


5. Turn the ratchet clockwise. That will raise the jack


lift head a little.


6. Position the jack under the vehicle.

7. Raise the vehicle by turning the ratchet clockwise.


Make sure the UP mark faces you. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit underneath the wheel well.


8. Remove all the wheel nuts and take off the flat tire.


5-78


10. Put on the compact spare tire. Put the nuts on by hand. Make sure the cone-shaped end is toward the wheel. Tighten each nut by hand until the wheel is held against the hub. If a nut can’t be turned by hand, use the extension and see your dealer as soon as possible.


9. Remove any rust or dirt from the wheel bolts,


mounting surfaces and spare wheel.


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 a 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.


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


11. Lower the vehicle by turning the ratchet


counterclockwise. Lower the jack completely.


5-79


12. Tighten the wheel nuts


firmly in a crisscross sequence as shown. Turn the ratchet clockwise with the UP mark facing you.


Notice: Improperly tightened wheel nuts can lead to brake pulsation and rotor damage. To avoid expensive brake repairs, evenly tighten the wheel nuts in the proper sequence and to the proper torque specification. See “Capacities and Specifications” in the index for the wheel nut torque specification.


13. Remove the wheel blocks. Notice: Wheel covers won’t fit on your compact spare. If you try to put a wheel cover on your compact spare, you could damage the cover or the spare.


Incorrect wheel nuts or improperly tightened wheel nuts can cause the wheel to come 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. Stop somewhere as soon as you can and have the nuts tightened with a torque wrench to the proper torque specification. See “Capacities and Specifications” in the Index for wheel nut torque specification.


5-80


Stori J a Flat or Spare Tire and Tools


Storing a jack, a tire, or other equipment in the passenger compartment of the vehicle could cause injury. In a sudden stop or collision, loose equipment could strike someone. Store all these in the proper place.


1. Put the flat tire on the ground at the rear of the


vehicle with the valve stem pointed down.


2. Tilt the retainer plate downward and through the


wheel opening. Make sure it is fully seated across the underside of the wheel. Attach the ratchet, with the UP side facing you, to the extension.


3. Put the flat end of the extension on an angle


through the hole in the rear door frame, above the bumper. The compact spare is for temporary use only. Replace the compact spare tire with a full-size tire as soon as you can. See Compact Spare Tire on page 5-82. See the storage instructions label to restore your compact spare properly.


4. Raise the tire fully against the underside of the


vehicle by turning the ratchevwheel wrench until you hear two clicks or feel it skip twice. The spare tire hoist cannot be overtightened.


5. Make sure the tire is stored securely. Push, pull,


and then try to rotate or turn the tire. If the tire moves, use the ratchet/wheel wrench to tighten the cable. Return the jacking equipment to its proper location.


5-81


Compact Spare Tire Although the compact spare tire was fully inflated when your vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on your vehicle, you should stop as soon as possible and make sure your spare tire is correctly inflated. The compact spare is made to perform well at speeds up to 65 mph (1 05 km/h) for distances up to 3,000 miles (5 000 km), so you can finish your trip and have your full-size tire repaired or replaced where you want. Of course, it’s best to replace your spare with a full-size tire as soon as you can. Your spare will last longer and be in good shape in case you need it again.


Notice: When the compact spare is installed, don’t take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Don’t use your compact spare on other vehicles. And don’t mix your compact spare tire or wheel with other wheels or tires. They won’t fit. Keep your spare tire and its wheel together. Notice: Tire chains won’t fit your compact spare. Using them can damage your vehicle and can damage the chains too. Don’t use tire chains on your compact spare.

Appearance Care Remember, cleaning products can be hazardous. Some are toxic. Others can burst into flames if you strike a match or get them on a hot part of the vehicle. Some are dangerous if you breathe their fumes in a closed space. When you use anything from a container to clean your vehicle, be sure to follow the manufacturer’s warnings and instructions. And always open your doors or windows when you’re cleaning the inside. Never use these to clean your vehicle: 0 Gasoline 0 Benzene 0 Naphtha


Carbon Tetrachloride Acetone Paint Thinner Turpentine Lacquer Thinner Nail Polish Remover


They can all be hazardous - some more than others -and


they can all damage your vehicle, too.


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


Alcohol Laundry Soap Bleach Reducing Agents


Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl, leather, plastic and painted surfaces with a clean, damp cloth. FabridCarpet Your dealer has cleaners for the cleaning of fabric and carpet. They will clean normal spots and stains very well. You can get GM - approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on page 5-89.


5-83


Special Fabric Cleaning Problems Stains caused by such things as catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, vomit, urine and blood can be removed as follows:


1. Carefully scrape off excess stain, then sponge the


soiled area with cool water.


2. If a stain remains, follow the cleaner instructions


described earlier.


3. If an odor lingers after cleaning vomit or urine,


treat the area with a watedbaking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water.


4. Let dry. Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows:


1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the cleaner instructions


described earlier.


Here are some cleaning tips:


Always read the instructions on the cleaner label. Clean up stains as soon as you can - before they set. Carefully scrape off any excess stain. Use a clean cloth or sponge, and change to a clean area often. A soft brush may be used if stains are stubborn. If a ring forms on fabric after spot cleaning, clean the entire area immediately or it will set.


Using Cleaner on Fabric 1. Vacuum and brush the area to remove any loose dirt. 2. Always clean a whole trim panel or section.


Mask surrounding trim along stitch or welt lines.


3. Follow the directions on the container label. 4. Apply cleaner with a clean sponge. Don’t saturate


the material and don’t rub it roughly.


5. As soon as you’ve cleaned the section, use a


sponge to remove any excess cleaner.


6. Wipe cleaned area with a clean, water-dampened


towel or cloth.


7. Wipe with a clean cloth and let dry.


5-84


Vinyl Use warm water and a clean cloth.


Rub with a clean, damp cloth to remove dirt. You may have to do this more than once.


0 Things like tar, asphalt and shoe polish will stain if


you don’t get them off quickly. Use a clean cloth and vinyl/leather cleaner. See your dealer for this product.


Leather Use a soft cloth with lukewarm water and a mild soap or saddle soap and wipe dry with a soft cloth. Then, let the leather dry naturally. Do not use heat to dry. 0 For stubborn stains, use a leather cleaner. See your


dealer for this product.


0 Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather. Soiled or stained leather should be cleaned immediately. If dirt is allowed to work into the finish, it can harm the leather.


Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish. Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See GM Vehicle Care/Appearance Materials on page 5-89. Notice: Don’t use abrasive cleaners on glass, because they may cause scratches. Avoid placing decals on the inside rear window, since they may have to be scraped off later. If abrasive cleaners are used on the inside of the rear window, an electric defogger element may be damaged. Any temporary license should not be attached across the defogger grid.


5-85


Care of Safety Belts Keep bel- ;lean -.--I -’ry.


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


Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See Part D: Recommended Fluids and Lubricants on page 6-32.


Cleaning the Outside of Your Vehicle The paint finish on your vehicle provides beauty, depth of color, gloss retention and durability. Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Don’t wash your vehicle in the direct rays of the sun. Use a car washing soap. Don’t use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. You can get GM-approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on page 5-89. Don’t use cleaning agents that are petroleum based, or that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or an all-cotton towel to avoid surface scratches and water spotting. High pressure car washes may cause water to enter your vehicle. Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under “Washing Your Vehicle.”


5-86


Finish Care Occasional waxing or mild polishing of your vehicle by hand may be necessary to remove residue from the paint finish. You can get GM-approved cleaning products from your dealer. See GM Vehicle Care/Appearance Materials on page 5-89. If your vehicle has a “basecoaflclearcoat” paint finish. The clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoaflclearcoat paint finish. Nofice: Machine compounding or aggressive polishing on a basecoatlclearcoat paint finish may dull the finish or leave swirl marks. Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your vehicle garaged or covered whenever possible.


Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts. Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with a full-strength glass cleaning liquid. The windshield is clean if beads do not form when you rinse it with water. Grime from the windshield will stick to the wiper blades and affect their performance. Clean the blade by wiping vigorously with a cloth soaked in full-strength windshield washer solvent. Then rinse the blade with water. Check the wiper blades and clean them as necessary; replace blades that look worn.


5-87


Aluminum Wheels Keep your wheels clean using a soft clean cloth with mild soap and water. Rinse with clean water. After rinsing thoroughly, dry with a soft clean towel. A wax may then be applied. The surface of these wheels is similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, abrasive polishes, abrasive cleaners, cleaners with acid, or abrasive cleaning brushes on them because you could damage the surface. Do not use chrome polish on aluminum wheels. Don’t take your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Tires To clean your tires, use a stiff brush with tire cleaner. Nofice: When applying a tire dressing, always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle. Petroleum-based products may damage the paint finish and tires.


Sheet Metal Damage If your vehicle is damaged and requires sheet metal repair or replacement, make sure the body repair shop applies anti-corrosion material to parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty. Finish Damage Any stone chips, fractures or deep scratches in the finish should be repaired right away. Bare metal will corrode quickly and may develop into major repair expense. Minor chips and scratches can be repaired with touch-up materials avaliable from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop.


5-88


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 debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you. 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, GM will repair, at no charge to the owner, the surfaces of new vehicles damaged by this fallout condition within 12 months or 12,000 miles (20 000 km) of purchase, whichever occurs first.

Service Parts Identification Label You’ll find this label on the front passenger door frame. It’s very helpful if you ever need to order parts. On this label is:


your VIN, the model designation, paint information and a list of all production options and special equipment.


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


Vehicle Identification


Vehicle Identification Number (VIN)


This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver’s side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Vehicle Certification and Service Parts labels and the certificates of title and registration. Engine Identification The 8th character in your VIN is the engine code. This code will help you identify your engine, specifications and replacement parts.

Electrical System


Add-on Electrical Equipment


Notice: Don’t add anything electrical to your vehicle unless you check with your dealer first. Some electrical equipment can damage your vehicle and the damage wouldn’t be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Your vehicle has an air bag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Air Bag-Equipped Vehicle on page 1-69. Headlamp Wiring The headlamp wiring is protected by a circuit breaker in the lamp switch. An electrical overload will cause the lamps to flicker on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away.


Windshield Wiper Fuses 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. Although the circuit is protected from electrical overload, overload due to heavy snow, etc., may cause wiper linkage damage. Always clear ice and heavy snow from the windshield before using the windshield wipers. 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 in the fuse panel 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.


5-92


Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. Spare fuses and a fuse puller are located in the underhood fuse block. You can remove fuses with the fuse puller. Remember to replace any of the spare fuses you use, so you will have some if you ever need them again. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without - like the radio or cigarette lighter - and use its fuse, if it is the correct amperage. Replace it as soon as you can. There are two fuse blocks in your vehicle: one is inside the vehicle and one is in the engine compartment.

Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance can even affect the quality of the air we breathe. Improper fluid levels or the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to keep your vehicle in good condition, please maintain your vehicle properly. Maintenance Requirements Maintenance intervals, checks, inspections and recommended fluids and lubricants as prescribed in this manual are necessary to keep your vehicle in good working condition. Any damage caused by failure to follow recommended maintenance may not be covered by warranty.

How This Section is Organized This maintenance schedule is divided into five parts: “Part A: Scheduled Maintenance Services” explains what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified serIine center do these jobs.


to do some jobs,


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


If you want to get the service information, see Service Publications Ordering Information on page 7- I 1.


“Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what you can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department or another qualified service center should perform. “Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.


6-3


Part A: Scheduled Maintenance Services In this part are scheduled maintenance services which are to be performed at the mileage intervals specified. Using Your Maintenance Schedule We at General Motors want to help you to keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your dealer.


This part tells you the maintenance services you should have done and when you should schedule them. When you go to your dealer for your service needs, you’ll know that GM-trained and supported sewice people will perform the work using GM parts. The proper fluids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses them. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. These schedules are for vehicles that:


carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s CertificationRire label. See Loading Your Vehicle on page 4-29. are driven on reasonable road surfaces within driving limits. use the recommended fuel. See Gasoline Octane on page 5-5.


6-4


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: Short Trip/City Definition Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle:


Most trips are less than 5 miles (8 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in stop-and-go traffic). You frequently tow a trailer or use a carrier on top of your vehicle. If the vehicle is used for delivery service, police, taxi or other commercial application.


One of the reasons you should follow this schedule if you operate your vehicle under any of these conditions is that these conditions cause engine oil to break down sooner.


Short Trip/City Intervals Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs first). Chassis Lubrication (or 3 months, whichever occurs first). Drive Axle Fluid Check. Every 6,000 Miles (IO 000 km): Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection, if driving in dusty conditions. Front Wheel Bearing Repack (two-wheel drive only) (or at each brake relining, whichever occurs first). Automatic Transmission Service (severe conditions only). Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Fuel Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions). Transfer Case Fluid Change. Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Positive Crankcase Ventilation (PCV) Valve Inspection. Every 150,000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs first). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages.


6-5


Long Trip/Highway Definition Follow this scheduled maintenance only if none of the conditions from the Short Trip/City Scheduled Maintenance are true. Do not use this schedule if the vehicle is used for trailer towing, driven in a dusty area or used off paved roads. Use the Short Trip/City schedule for these conditions. Driving a vehicle with a fully warmed engine under highway conditions will cause engine oil to break down slower.


Long Trip/Highway Intervals


Every 7,500 Miles (12 500 km): Engine Oil and Filter Change (or every 12 months, whichever occurs first). Chassis Lubrication (or 12 months, whichever occurs first). Drive Axle Fluid Check. Tire Rotation. Every 15,000 Miles (25 000 km): Automatic Transmission Service (severe conditions only). Every 30,000 Miles (50 000 km): Fuel Filter Replacement. Engine Air Cleaner Filter Replacement. Front Wheel Bearing Repack (two-wheel drive only) (or at each brake relining, whichever occurs first). Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions). Transfer Case Fluid Change. Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Positive Crankcase Ventilation (PCV) Valve Inspection. Every 150,000 Miles (240 000 km): Cooling System Service (or every 60 months, whichever occurs first). Engine Accessory Drive Belt Inspection. These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages.


6-6


Short Trip/City Scheduled Maintenance The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after IQ0,OOQ miles (166 000 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6-26 and Part C: Periodic Maintenance Inspections on page 6-30. Footnotes t The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. # Lubricate the front suspension, ball joints and kingpin bushings, steering linkage, parking brake cable guides and brake pedal springs. + A good time to check your brakes is during tire rotation.
