Turn off the engine and give the oil a few minutes to drain back into the oil pan. If you don’t, the oil dipstick might not show the actual level.


6-8


To Check Engine Oil Pull out the dipstick and clean it with a paper towel or cloth, then push it back in all the way. Remove it again, keeping the tip down.


When to Add Oil If the oil is at or below the ADD line, then you’ll need to add some oil. But you must use the right kind. This part explains what kind of oil to use. For crankcase capacity, see “Capacities and Specifications” in the Index.


NOTICE: Don’t add too much oil. If your engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, your engine could be damaged.


The engine oil filler cap is located on the driver’s side engine valve cover. Just fill it enough to put the level somewhere in the proper operating range. Push the dipstick all the way back in when you’re through.

What Kind of Oil fo Use Oils of the proper quality for your vehicle can be identified by looking for the “Starburst” symbol. The “Starburst” symbol indicates that the oil has been certified by the American Petroleum Institute (API), and is preferred for use in your gasoline engine.


If you change your own oil, be sure you use oil that has the “Starburst” symbol on the front of the oil container. If you have your oil changed for you, be sure the oil put into your engine is American Petroleum Institute certified for gasoline engines.

GM Goodwrench@ oil (in Canada, GM Engine Oil) meets all the requirements for your vehicle. Engine Oil Additives Don’t add anything to your oil. Your GM dealer is ready to advise if you think something should be added. When to Change Engine Oil See if any one of these is true for you: 0 Most trips are less than 5 to 10 miles (8 to 16 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).


0 You operate your vehicle in dusty areas or off-road frequently. 0 You frequently tow a trailer or use a carrier on top of your vehicle.


If any one of these is true for your vehicle, then you need to change your oil and filter every 3,000 miles (5 000 km) or 3 months - whichever comes first. If none of them is true, change the oil and filter every 7,500 miles (12 500 km) or 12 months - whichever comes first.

Four-wheel Drive Remote Oil Filter If your vehicle has four-wheel drive, you will have a remote oil filter. There is a special access door in the steering linkage shield assembly located under the radiator support. Twist the screw to lock or unlock the door.


Engine Coolant Heater An engine coolant heater can be a big help if you have to park outside in very cold weather, 0°F (-18 “C) or colder. If your vehicle has this option, see “Engine Coolant Heater” in the Index. What to Do with Used Oil Did you know that used engine oil contains certain elements that may be unhealthy for your skin and could even cause cancer? Don’t let used oil stay on your skin for very long. Clean your skin and nails with soap and water, or a good hand cleaner. Wash or properly throw away clothing or rags containing used engine oil. (See the manufacturer’s warnings about the use and disposal of oil products.) Used oil can be a real threat to the environment. If you change your own oil, be sure to drain all free-flowing oil from the filter before disposal. Don’t ever dispose of oil by putting it in the trash, pouring it on the ground, into sewers, or into streams or bodies of water. Instead, recycle it by taking it to a place that collects used oil. If you have a problem properly disposing of your used oil, ask your dealer, a service station or a local recycling center for help. Air Cleaner


To remove the rectangular air cleaner filter for the 4.3L (VIN W) engine, open both clamps and push the rear of the air cleaner back toward the rear of the engine compartment to change the filter.


6-13


While reassembling the air cleaner assembly, ensure that the air cleaner cover tabs are fully inserted into the slots in the air cleaner housing. On the 4.3L (VIN W) engine, also make certain that the PCV air tube is properly seated in the left hand valve cover. Refer to the Maintenance Schedule to determine when to redace the air filter. See “Scheduled Maintenance Services” in the Index.


NOTICE: If the air cleaner is off, a backfire can cause a damaging engine fire. And, dirt can easily get into your engine, which will damage it. Always have the air cleaner in place when you’re driving.


Automatic Transmission Fluid -When to Check and Change A good time to check your automatic transmission fluid level is when the engine oil is changed. Refer to the Maintenance Schedule to determine when to change your fluid. See “Scheduled Maintenance Services” in the Index. How to Check Because this operation can be a little difficult, you may choose to have this done at your GM dealership Service Department. If you do it yourself, be sure to follow all the instructions here, get a false reading on the dipstick.

NOTICE: Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.


Wait at least 30 minutes before checking the transmission fluid level if you have been driving:


When outside temperatures are above 90°F (32°C). At high speed for quite a while. In heavy traffic - especially in hot weather.


0 While pulling a trailer.


To get the right reading, the fluid should be at normal operating temperature, which is 180°F to 200°F (82°C to 93°C). To check transmissionfluid hot: Get the vehicle warmed up by driving about 15 miles (24 km) when outside temperatures are above 50°F (10°C). If it's colder than 50°F ( lO"C), drive the vehicle in THIRD GEAR (D) until the engine temperature gage moves and then remains steady for ten minutes. Then follow the hot check procedures. To check transmissionfluid cold: A cold check is rnaae after the vehicle has been sitting for eight hours or more with the engine off and is used only as a reference. Let the engine run at idle for five minutes if outside temperatures are 50°F (10°C) or more. If it's colder than 50°F (lO"C), you may have to idle the engine longer. Should the fluid level be low during a cold check, you must perform a hot check before adding fluid. This will give you a more accurate reading of the fluid level. To check the fluid hot or cold


Park your vehicle on a level place. Keep the engine running.


0 With the parking brake applied, place the shift lever in Park (P).


With your foot on the brake pedal, move the shift lever through each gear range, pausing for about three seconds in each range. Then, position the shift lever in Park (P). Let the engine run at idle for three minutes or more.

Then, without shutting off the engine, follow these steps:


1. Flip the handle


up and then pull out the dipstick and wipe it with a clean rag or paper towel.


2. Push it back in all the way, wait three seconds and then pull


it back out


again.


3. Check both sides of the dipstick, and read the lower level. The fluid


level must be in the COLD area for a cold check or in the HOT area or cross-hatched area for a hot check.


4. If the fluid level is in the acceptable range, push the dipstick back in all


the way; then flip the handle down to lock the dipstick in place.


6- 16


How to Add Fluid Refer to the Maintenance Schedule to determine what kind of transmission fluid to use. See “Recommended Fluids and Lubricants” in the Index. Add fluid only after checking the transmission fluid HOT. (A COLD check is used only as a reference.) If the fluid level is low, add only enough of the proper fluid to bring the level up to the HOT area for a hot check. It doesn’t take much fluid, generally less than a int. Don ’t overfill. We recommend you use only fluid labeled DEXRON -111, because fluid with that label is made especially for your automatic transmission. Damage caused by fluid other than DEXRON@-I11 is not covered by your new vehicle warranty.


After adding fluid, recheck the fluid level as described under “How to Check.”


0 When the correct fluid level is obtained, push the dipstick back in all


the way; then flip the handle down to lock the dipstick in place.


Manual Transmission Fluid When to Check A good time to have it checked is when the engine oil is changed. However, the fluid in your manual transmission doesn’t require changing. How to Check Because this operation can be a little difficult, you may choose to have this done at your GM dealership Service Department. If you do it yourself, be sure to follow all the instructions here, or you could get a false reading.


I NOTICE:


Too much or too little fluid can damage your transmission. Too much can mean that some of the fluid could come out and fall on hot engine parts or exhaust system parts, starting a fire. Be sure to get an accurate reading if you check your transmission fluid.


Check the fluid level only when your engine is off, the vehicle is parked on a level place and the transmission is cool enough for you to rest your fingers on the transmission case.

Brakes Brake Master Cylinder Your brake master cylinder is here. It is filled with DOT-3 brake fluid.


There are only two reasons why the brake fluid level in your master cylinder might go down. The first is that the brake fluid goes down to an acceptable level during normal brake lining wear. When new linings are put in, the fluid level goes back up. The other reason is that fluid is leaking out of the brake system. If it is, you should have your brake system fixed, since a leak or won’t work at means that sooner or later your brakes won’t work well, all. So, it isn’t a good idea to “top off’ your brake fluid. Adding brake fluid won’t correct a leak. If you add fluid when your linings are worn, then you’ll have too much fluid when you get new brake linings. You should add (or remove) brake fluid, as necessary, only when work is done on the brake hydraulic system.


Refer to the Maintenance Schedule to determine when to check your brake fluid. See “Periodic Maintenance Inspections” in the Index.

To Check Brake Fluid


.. .


You can check the brake fluid without taking off the cap. Just look at the windows on the brake fluid reservoir. The fluid levels should be above MIN. If they aren’t, have your brake system checked to see After work is done on the brake hydraulic system, make sure the levels are above MIN and below the top of each window.

NOTICE: 0 Don’t let someone put in the wrong kind of fluid. For


example, just a few drops of mineral-based oil, such as engine oil, in your brake system can damage brake system parts so badly that they’ll have to be replaced.


0 Brake fluid can damage paint, so be careful not to spill brake fluid on your vehicle. If you do, wash it off immediately. See “Appearance Care” in the Index.

Brake Wear Your vehicle has front disc brakes and rear drum brakes. Disc brake pads have built-in wear indicators that make a high-pitched warning sound when the brake pads are worn and new pads are needed. The sound may come and go or be heard all the time your vehicle is moving (except when you are pushing on the brake pedal firmly).


NOTICE: Continuing to drive with worn-out brake pads could result in costly brake repair.


Some driving conditions or climates may cause a brake squeal when the brakes are first applied or lightly applied. This does not mean something is wrong with your brakes. if you i?v& hear a Your rear drum brakes don’t have wear indicators, but rear brake rubbing noise, have the rear brake linings inspected. Also, the rear brake drums should be removed and inspected each time the tires are removed for rotation or changing. When you have the front brakes replaced, have the rear brakes inspected, too. Brake linings should always be replaced as complete axle sets. Brake Pedal Travel See your dealer if the brake pedal does not return to normal height, or if there is a rapid increase in pedal travel. This could be a sign of brake trouble. Brake Adjustment Every time you make a brake stop, your disc brakes adjust for wear. If your brake pedal goes down farther than normal, your rear drum brakes may need adjustment. Adjust them by backing up and firmly applying the brakes a few times.

Replacing Brake System Parts The braking system on a modern vehicle is complex. Its many parts have to be of top quality and work well together braking. Vehicles we design and test have top-quality GM brake parts in them, as your vehicle does when it is new. When you replace parts of your braking system - for example, when your brake linings wear down and you have to have new ones put in - be sure you get new genuine GM replacement parts. If you don’t, your brakes may no longer work properly. For example, if someone puts in brake linings that are wrong vehicle, the balance between your front and rear brakes can change - for the worse. The braking performance you’ve come to expect can change in many other ways if someone puts in the wrong replacement brake parts. Battery Every new vehicle has a Delco Freedom@ battery. You never have to add water to one of these. When it’s time for a new battery, we recommend a Delco Freedom@ battery. Get one that has the replacement number shown on the original battery’s label.

Air Conditioning Every now and then have your dealership check your air conditioning system to be sure it has not lost any cooling ability. If you think the system is not working properly, have your dealership check it out as soon as possible. The air conditioning will not work when the temperature is below 40°F (4°C).


Lock Cylinders To be sure your locks operate properly, they must be lubricated. Refer to the Maintenance Schedule to determine how often to lubricate them and what type of lubricant to use. You should not use penetrating oils because they could wash out me factory installed lubricant and cause the lock to bind. De-icers which contain alcohol could also wash away the lubricant, so be sure to lubricate the lock after using a de-icer of this type. Exhaust System To help prevent damage to your exhaust system, do not continue to drive your vehicle if you notice:


0 Engine misfiring 0 Loss of performance 0 Exhaust system components hanging lower than normal. 0 Loud exhaust system noises. 0 Other unusual operating conditions

Ma/function Indicator Lamp (SERVICE ENGINE SOON) This light on your instrument panel lets you know when your emission system needs service. See “Malfunction Indicator Lamp” in the Index. 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 vehicle. If your spare tire is a different brand than your road tires, you will have a tire warranty folder from each of these manufacturers.


Inflation - lire Pressure The Certificationire label which is on the driver’s door lock pillar, 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.


6-41


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:


Unusual wear Bad handling Rough ride


0 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.


How to Check Use a good quality pocket-type gage to check tire pressure. Simply looking at the tires will not tell you the pressure, especially if you have radial tires - which may look properly inflated even if they’re underinflated. If your tires have valve caps, be sure to put them back on. They help prevent leaks by keeping out dirt and moisture.

lire Inspection and Rotation Tires should be inspected every 6,000 to 8,000 miles (10 000 to 13 000 km) for any signs of unusual wear. If unusual wear 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. The purpose of regular rotation is to achieve more uniform wear for all tires on the vehicle. The first rotation is the most important.

When It’s Time for New Tires


Tkead Wear Indicators 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


0 You can see the indicators at three or more places around the tire. 0 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. The tire has a bump, bulge or split. The tire has a puncture, cut, or other damage that can’t be repaired well because of the size or location of the damage.


Buying New Tires To find out what kind and size of tires you need, look at the Certificatioflire 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.


6-44


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 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 lowest are: A, B, and C . They represent the tire’s ability to stop on wet pavement as measured under controlled conditions on specified government test surfaces of asphalt and concrete. A tire marked C may have 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 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.


6-45


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. 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 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 GM 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.


6-46


I NOTICE:


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

Tire Chains


NOTICE: If your vehicle has P235/75R15 or P235/70R15 size tires, don’t use tire chains; they can damage your vehicle. If you have other size tires, 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-wheeldrive 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 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.

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.


6-48


Never use these to clean your vehicle:


Gasoline Benzene Naphtha


0 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


0 Reducing Agents Cleaning the Inside of Your Vehicle Use a vacuum cleaner often to get rid of dust and loose dirt. Wipe vinyl or leather with a clean, damp cloth. Your GM 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.


0 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. 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.


6-49


Using Foam-Type Cleaner on Fabric 0 Vacuum and brush the area to remove any loose dirt. 0 Always clean a whole trim panel or section. Mask surrounding trim


along stitch or welt lines.


0 Mix Multi-Purpose Powdered Cleaner following the directions on the


container label.


0 Use suds only and apply with a clean sponge. 0 Don’t saturate the material.


Don’t rub it roughly.


0 As soon as you’ve cleaned the section, use a sponge to remove the


suds. Rinse the section with a clean, wet sponge.


0 Wipe off what’s left with a slightly damp paper towel or cloth. 0 Then dry it immediately with a blow dryer or a heat lamp. NOTICE: Be careful. A blow dryer may scorch the fabric.


0 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: 0 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 of the cloth.

Fabric Protection Your vehicle has upholstery and carpet that has been treated with Scotchgard" Fabric Protector, a 3M product. Scotchgard R'( 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 and carpet often to keep it looking new. Further information on cleaning is available by calling 1-800-433-3286 (in Minnesota, 1-800-642-6 167). SpeciaI CIeaning Problems


Greasy or Oily Stains Stains caused by grease, oil, butter, margarine, shoe polish, coffee with cream, chewing gum, cosmetic creams, vegetable oils, wax crayon, tar and asphalt can be removed as follows: 0 Carefully scrape off excess stain.


Follow the solvent-type instructions described earlier.


0 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.


Non-Greasy Stains Stains caused by catsup, coffee (black), egg, fruit, fruit juice, milk, soft drinks, wine, vomit, urine and blood can be removed as follows:


Carefully scrape off excess stain, then sponge the soiled area with cool water. 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 waterhaking 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 Stains caused by candy, ice cream, mayonnaise, chili sauce and unknown stains can be removed as follows:


Carefully scrape off excess stain, then clean with cool water and allow to dry. If a stain remains, clean it with solvent-type cleaner.


6-51


Cleaning Vinyl Use warm water and a clean cloth.


Rub with a clean, damp cloth to remove dirt. You may have to do it more than once. Things like tar, asphalt and shoe polish will stain if you don’t get them off quickly. Use a clean cloth and a solvent-type vinyl cleaner.


C/eaning 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 alcohol) and 90% water. Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish or shoe polish on leather.


0 Soiled leather should be cleaned immediately.


If dirt is allowed to work


into finish, it can harm the leather.


Creaning the Top of the Instrument Panel Use only mild soap and water to clean the top surfaces 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. Care of Safety Belts Keep belts clean and dry.

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 the Outside of the Windshield, Backglass 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. 105001 1). The windshield is clean if beads do not form when you rinse it with water. 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. Weatherstrips Silicone grease on weatherstrips will make them last 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 & Lubricants” in the Index.)

by washing


Washing Your Vehicle The best way to preserve your vehicle’s finish is to keep it clean 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 that contain acid or abrasives. All cleaning agents should be flushed promptly and not allowed to dry on the surface, or they could stain. Dry the finish with a soft, clean chamois or a 100% cotton towel to avoid surface scratches and water spotting. High pressure vehicle washes may cause water to enter your vehicle. 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 “basecoatklearcoat” 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 basecoatklearcoat paint finish.


NOTICE: 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. 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.


If necessary, use

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 GM 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. Aluminum Wheels (If So Equipped) Your aluminum wheels have a protective coating similar to the painted surface of your vehicle. Don’t use strong soaps, chemicals, chrome polish, abrasive cleaners or abrasive cleaning brushes on them because you could damage this coating. After rinsing thoroughly, a wax may be applied.


1 NOTICE:


If you have aluminum wheels, don’t use an automatic vehicle wash that has hard silicon carbide cleaning brushes. These brushes can take the protective coating off your aluminum wheels.


Tires To clean your tires, use a stiff brush with a tire cleaner. When applying a tire dressing always take care to wipe off any overspray or splash from painted surfaces. Petroleum-based products may damage the paint finish. 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. 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.


6-55


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 vehicle 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 comes first.

Scheduled Maintenance Services


Section


IMPORTANT: KEEP ENGINE OIL AT THE PROPER


LEVELAND CHANGE AS RECOMMENDED


This section covers the maintenance required for your vehicle. Your vehicle needs these services to retain its safety, dependability and emission control performance.


Protection Plan


Have you purchased the GM Protection Plan? The Plan supplements your new vehicle warranties. See your GM dealer for details. 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 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.


7-1


How This Section is Organized The remainder of this section is divided into five parts: “Part 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 service department or another qualified service center do these jobs.


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. “Part 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. “Part C: Periodic Maintenance Inspections” explains important inspections that your GM dealer’s service department or another qualified service center should perform. “Part 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. “Part 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 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.

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 GM vehicles, maintenance needs vary. You may even need more frequent checks and replacements than you’ll find in the schedules in this section. So please read this section and note how you drive. If you have any questions on how to keep your vehicle in good condition, see you GM 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:


carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s CertificationEire label. See “Loading Your Vehicle’’ in the Index. are driven on reasonable road surfaces within legal driving limits. are driven off-road in the recommended manner. See “Off Road Driving With Your Four-wheel Drive Vehicle” in the Index. 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:


7-3


I Schedule


Follow Maintenance Schedule I if any one of these is true for your vehicle: Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly important when outside temperatures are below freezing. Most trips include extensive idling (such as frequent driving in go traffic).

Footnotes ? 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 vehicle useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded in “Section E: Maintenance Record.” ** Drive axle service:


Locking Differential - Drain fluid and refill at first engine oil change. At subsequent oil changes, check fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km). Standard Differential - Check fluid level and add fluid as needed at every oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km) . More frequent lubrication may be required for heavy-duty or off-road use.
