Tires Your new vehicle 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 GM Warranty booklet for details.


CAUTION:


Poorly maintained and improperly used tires are dangerous. D 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)


CAUTION: (Continued)


D 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.


D 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.


D Worn, old tires can cause accidents. If your


tread is badly worn, or if your tires have been damaged, replace them.


6-47


Inflation -- Tire Pressure The Certification/Tire label, which is on the driver’s door edge, above the door latch, 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).


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: D Too much flexing D Too much heat D Tire overloading D Bad wear D Bad handling D Bad fuel economy


NOTICE: (Continued)


6-48


NOTICE: (Continued)


If your tires have too much air (overinflation), you can get the following: D Unusual wear D Bad handling D Rough ride D Needless damage from road hazards


When to Check Check your tires once a month or more. Also, check the tire pressure of the spare tire. If you have a compact spare tire, it should be at 60 psi (420 kPa).


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 Inspection and Rotation Tires should be rotated every 6,000 to 8,000 miles (10 000 to 13 000 km). Any time you notice unusual wear, rotate your tires as soon as possible and check wheel alignment. Also check for damaged tires or wheels. See “When It’s Time for New Tires” and “Wheel Replacement” later in this section for more information. Make sure the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrench to tighten the cable. See “Storing a Flat or Spare Tire and Tools” in the Index. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Scheduled Maintenance Services” in the Index for scheduled rotation intervals.


When rotating your tires, always use one of the correct rotation patterns shown here.


6-49


If your vehicle has a compact spare tire or a spare tire that does not match your vehicle’s regular road tires and wheels in size and type, do not include the spare in the tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Certification/Tire label. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” in the Index.


CAUTION:


Rust or dirt on a wheel, or on the parts to which it is fastened, can make 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 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. See “Changing a Flat Tire” in the Index.


6-50


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: D You can see the indicators at three or more places


around the tire.


D You can see cord or fabric showing through the


tire’s rubber.


D The tread or sidewall is cracked, cut or snagged deep


enough to show cord or fabric.


D The tire has a bump, bulge or split. D 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 Certification/Tire 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.


CAUTION:


Mixing tires could cause you to lose control while driving. If you mix tires of different sizes or types (radial and bias-belted tires), the vehicle may not handle properly, and you could have a crash. Using tires of different sizes may also cause damage to your vehicle. Be sure to use the same size and type tires on all wheels. It’s all right to drive with your compact spare (if you have one). It was developed for use on your vehicle.


CAUTION:


If you use bias-ply tires on your vehicle, the wheel rim flanges could develop cracks after many miles of driving. A tire and/or wheel could fail suddenly, causing a crash. Use only radial-ply tires with the wheels on your vehicle.


6-51


Uniform Tire Quality Grading Quality grades can be found where applicable on the tire sidewall between tread shoulder and maximum section width. For example: Treadwear 200 Traction AA Temperature A 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. Traction -- AA, A, B, C The traction grades, from highest to lowest, are AA, A, B, and C. Those grades 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 straight-ahead braking traction tests, and does not include acceleration, cornering, hydroplaning, or peak traction characteristics.


6-52


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.


6-53


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.


CAUTION:


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 or tire chain clearance to the body and chassis.


See “Changing a Flat Tire” in the Index for more information.


Used Replacement Wheels


CAUTION:


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


6-54


Tire Chains


CAUTION:


If your vehicle has P235/75R15, P235/70R15, P235/55R16 or 31x10.50R15LT/C size tires, don’t use tire chains. They can damage your vehicle because there’s not enough clearance. Tire chains used on a vehicle without the proper amount of clearance can cause damage to the brakes, suspension or other vehicle parts. The area damaged by the tire chains could cause you to lose control of your vehicle and you or others may be injured in a crash. Use another type of traction device only if its manufacturer recommends it for use on your vehicle and tire size combination and road conditions. Follow that manufacturer’s instructions. To help avoid damage to your vehicle, drive slowly, readjust or remove the device if it’s contacting your vehicle, and don’t spin your wheels. If you do find traction devices that will fit, install them on the rear tires.


NOTICE:


If your vehicle has a tire size other than P235/75R15, P235/70R15, P235/55R16 or 31x10.50R15LT/C, 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 drive axle tires (four-wheel-drive vehicles can use chains on both axles) 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.

Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle: D Alcohol D Laundry Soap D Bleach D 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. Cleaning of Fabric/Carpet 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 “Appearance Care and Materials” in the Index.


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 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: D Gasoline D Benzene D Naphtha D Carbon Tetrachloride D Acetone D Paint Thinner D Turpentine D Lacquer Thinner D Nail Polish Remover They can all be hazardous -- some more than others -- and they can all damage your vehicle, too.


6-56


Here are some cleaning tips: D Always read the instructions on the cleaner label. D Clean up stains as soon as you can -- before they set. D Carefully scrape off any excess stain. D Use a clean cloth or sponge, and change to a clean


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


D 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.


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 water/baking 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. First, clean with cool water and allow to dry


completely.


3. If a stain remains, follow the cleaner instructions


described earlier.


6-57


Cleaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions. Cleaning Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface finish. Cleaning Wood Panels Use a clean cloth moistened in warm, soapy water (use mild dish washing soap). Dry the wood immediately with a clean cloth.


Cleaning Vinyl Use warm water and a clean cloth. D Rub with a clean, damp cloth to remove dirt. You


may have to do it more than once.


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


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


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


dealer for this product.


D Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather.


D Soiled or stained leather should be cleaned


immediately. If dirt is allowed to work into the finish, it can harm the leather.


6-58


Care of Safety Belts Keep belts clean and dry.


CAUTION:


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


Cleaning Glass Surfaces Glass should be cleaned often. GM Glass Cleaner or a A liquid household glass cleaner will remove normal tobacco smoke and dust films on interior glass. See “Appearance Care and Materials” in the Index.


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.


6-59


Cleaning the Outside of the Windshield and Wiper Blades If the windshield is not clear after using the windshield washer, or if the wiper blade chatters when running, wax, sap or other material may be on the blade or windshield. Clean the outside of the windshield with 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. Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth at least every six months. During very cold, damp weather more frequent application may be required. See “Recommended Fluids and Lubricants” in the Index.


6-60


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 “Appearance Care and Materials” in the Index. 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.” 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 “Appearance Care and Materials” in the Index. Your vehicle has a “basecoat/clearcoat” 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 basecoat/clearcoat paint finish.


NOTICE:


Machine compounding or aggressive polishing on a basecoat/clearcoat 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.


6-61


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. Cleaning Aluminum Wheels (If Equipped) 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 silicon carbide tire cleaning brushes. These brushes can also damage the surface of these wheels. Cleaning Tires To clean your tires, use a stiff brush with a tire cleaner.


NOTICE:


When applying a tire dressing always take care to wipe off any overspray or splash from all painted surfaces on the body or wheels of the vehicle. Petroleum-based products may damage the paint finish 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 the parts repaired or replaced to restore corrosion protection. Original manufacturer replacement parts will provide the corrosion protection while maintaining the warranty.


6-62


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.


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 a major repair expense. Minor chips and scratches can be repaired with touch-up materials available from your dealer or other service outlets. Larger areas of finish damage can be corrected in your dealer’s body and paint shop. Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, accelerated corrosion (rust) can occur on the underbody parts such as fuel lines, frame, floor pan and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and other debris can collect. Dirt packed in closed areas of the frame should be loosened before being flushed. Your dealer or an underbody car washing system can do this for you.

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. Service Parts Identification Label You’ll find this label on the inside of the glove box. It’s very helpful if you ever need to order parts. On this label is: D your VIN, D the model designation, D paint information and D a list of all production options and special


equipment.


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


6-65


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” in the Index.


Headlamps The headlamp wiring is protected by an internal circuit breaker. An electrical overload will cause the lamps to go on and off, or in some cases to remain off. If this happens, have your headlamp wiring checked right away. Windshield Wipers The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice the wiper will stop until the motor cools. If the overload is caused by some electrical problem, 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.


6-66


Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses and circuit breakers. This greatly reduces the chance of fires caused by electrical problems. Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and don’t have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without -- like the radio or cigarette lighter -- and use its fuse, if it is the correct amperage. Replace it as soon as you can.

Introduction 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.


Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your Warranty and Owner Assistance booklet or your dealer for details.


7-2


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 service center do these jobs.


CAUTION:


Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, 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 and Owner Publications” in the Index.


“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.


7-3


Part A: Scheduled Maintenance Services Using Your Maintenance Schedule 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 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. 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.


The proper fluids and lubricants to use are listed in Part 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. These schedules are for vehicles that: D carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Certification/Tire label. See “Loading Your Vehicle” in the Index.


D are driven on reasonable road surfaces within legal


driving limits.


D are driven off-road in the recommended manner. See


“Off-Road Driving With Your Four-Wheel-Drive Vehicle” in the Index.


D use the recommended 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:


7-4


Scheduled Maintenance


Short Trip/City Definition


Short Trip/City Intervals


Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle: D Most trips are less than 5 miles (8 km). This is


particularly important when outside temperatures are below freezing.


D Most trips include extensive idling (such as frequent


driving in stop-and-go traffic).


D Your vehicle has the 2200 L4 (Code 5) flexible


fuel engine and you have used ethanol fuel (85% Ethanol/E-85).


D You frequently tow a trailer. D 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.


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 Service.


Every 6,000 Miles (10 000 km): Tire Rotation. Every 15,000 Miles (25 000 km): Engine Air Cleaner Filter Inspection, if driving in dusty conditions. Front Wheel Bearing Repack (2WD 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 (4.3L V6 engine only).


Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions).


Every 60,000 Miles (100 000 km): Engine Accessory


Drive Belt Inspection.


(Continued)


7-5


Scheduled Maintenance


Short Trip/City Intervals


Long Trip/Highway Definition


Every 90,000 Miles (150 000 km): Fuel Filter


Replacement (2200 L4 engine only).


Every 100,000 Miles (166 000 km): Spark Plug Wire


Inspection. Spark Plug Replacement. 4.3L V6 Engine Only: Positive Crankcase Ventilation (PCV) Valve Inspection.


Every 150,000 Miles (240 000 km): Cooling System


Service (or every 60 months, whichever occurs first).


These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages.


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. Do not use this schedule if you have the 2200 L4 (Code 5) flexible fuel engine and you have used ethanol fuel (85% Ethanol/E-85). 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.


7-6


Scheduled Maintenance


Long Trip/Highway Intervals


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 every 12 months, whichever occurs first). Drive Axle Service. 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 (4.3L V6 engine only). Engine Air Cleaner Filter Replacement. Front Wheel Bearing Repack (2WD only) (or at each brake relining, whichever occurs first).


Every 50,000 Miles (83 000 km): Automatic Transmission Service (normal conditions).


Every 60,000 Miles (100 000 km): Engine Accessory


Drive Belt Inspection.


Every 90,000 Miles (150 000 km): Fuel Filter


Replacement (2200 L4 engine only).


Every 100,000 Miles (166 000 km): Spark Plug Wire


Inspection. Spark Plug Replacement. 4.3L V6 Engine Only: Positive Crankcase Ventilation (PCV) Valve Inspection.


Every 150,000 Miles (240 000 km): Cooling System


Service (or every 60 months, whichever occurs first).


These intervals only summarize maintenance services. Be sure to follow the complete scheduled maintenance on the following pages.


7-7


Short Trip/City Scheduled Maintenance


The services shown in this schedule up to 100,000 miles (166 000 km) should be repeated after 100,000 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 “Owner Checks and Services” and “Periodic Maintenance Inspections” following. Footnotes [ 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, steering linkage, parking brake cable guides, propshaft splines, universal joints and brake pedal springs. + A good time to check your brakes is during tire rotation. See “Brake System Inspection” under “Periodic Maintenance Inspections” in Part C of this schedule. ** Drive axle service. See “Recommended Fluids and Lubricants” in the Index for proper lubricant to use: D Check fluid level and add fluid as needed. If driving in dusty areas or when towing a trailer, drain fluid and refill every 15,000 miles (25 000 km).


D If your vehicle has a locking differential, drain fluid


and refill at first engine oil change.


D More frequent lubrication may be required for


heavy-duty or off-road use.
