2003 Pontiac Bonneville Owners Manual

Your vehicle has a visual optical headlamp aiming system equipped with horizontal aim indicators. The aim has been preset at the factory and should need no further adjustment. This is true even though your horizontal aim indicators may not fall exactly on the “0” (zero) marks on their scales.

5-52

If your vehicle is damaged in an accident, the headlamp aim may be affected. Aim adjustment to the low beam may be necessary if it is difficult to see lane markers (for horizontal aim), or if oncoming drivers flash their high beams at you (for vertical aim). If you believe your headlamps need to be re-aimed, we recommend that you take your vehicle to your dealer for service. However, it is possible for you to re-aim your headlamps as described in the following procedure. Notice: To make sure your headlamps are aimed properly, read all the instructions before beginning. Failure to follow these instructions could cause damage to headlamp parts. The vehicle should be properly prepared as follows:

The vehicle should be placed so the headlamps are 25 ft. (7.6 m) from a light colored wall or other flat surface. The vehicle must have all four tires on a perfectly level surface which is level all the way to the wall or other flat surface. The vehicle should be placed so it is perpendicular to the wall or other flat surface.

The headlamp aiming devices are under the hood near the headlamps.

0 The vehicle should not have any snow, ice or mud

attached to it.

* The vehicle should be fully assembled and all other work stopped while headlamp aiming is being done.

0 The vehicle should be normally loaded with a

full tank of fuel and one person or 160 Ibs. (75 kg) on the driver’s seat. Tires should be properly inflated.

Headlamp aiming is done with the vehicle low beam lamps. The high beam lamps will be correctly aimed if the low beam lamps are aimed properly.

If you believe your headlamps need horizontal (lefthight) adjustment, follow the horizontal aiming procedure. If you believe your headlamps need only vertical -:-:-- \Up/UUvvl I) ~ U J U ~ C I procedure. Adjustment screws can be turned with an E8 Torx@ socket or T i 5 Torx@ screwdriver.

Headlamp Horizontal Aiming Turn the horizontal aiming screw (A) until the indicator (B) is lined up with zero.

1. Find the aim dot on the lens of the low

beam lamps.

Once the horizontal aim is adjusted, then adjust the vertical aim. Headlamp Vertical Aiming

Notice: Horizontal aiming must be performed before making any adjustments to the vertical aim. Adjusting the vertical aim first will result in an incorrect headlamp aim.

5-54

2. Measure the distance from the ground to the aim dot on each lamp; if left low beam, subtract two inches. Record this distance.

3. At the wall or other flat surface, measure from the ground upward the recorded distance from Step 2 and draw or tape a horizontal line the width of the vehicle.

4. Turn on the low-beam headlamps and place a piece of cardboard or equivalent in front of the headlamp not being aimed. This should allow only the beam of light from the headlamp being aimed to be seen on the flat surface.

Norice: DO noi cover a heariiarnp iu iii-lpi-uie 5386~ cut-off when aiming. Covering a headlamp may cause excessive heat build-up which may cause damage to the headlamp.

5. Turn the vertical aiming

screw (C) until the headlamp beam is aimed to the horizontal tape line. The top edge of the cut-off should be positioned at the bottom edge of the horizontal tape line.

6. Repeat Steps 4 and 5 for the opposite headlamp.

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 P

tiac Warranty booklet for details.

Poorly maintained and improperly used tires are dangerous. 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. 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.

CAUTION:

(Continued)

5-62

Overinflated tires are more likely be cut, punctured or broken by a sudden impact - such as when you hit a pothole. Keep tires at the recommended pressure. Worn, old tires can cause accidents. If your tread is badly worn, or if your tires have been damaged, replace them. See ”Inflation - Tire Pressure” in this section for inflation pressure adjustment for higher speed driving.

Inflation -- Tire Pressure

The Tire-Loading Information label, which is on the rear edge of the driver’s door, shows the correct inflation pressures for your tires when they’re cold. “Cold” means your vehicle has been sitting for at least three hours or driven no more than 1 mile (1.6 km). If you’ll be driving at high speeds (e.g., speeds of 100 mph (160 km/h) or higher), where it is legal, set the cold inflation pressure to the maximum inflation pressure shown on the tire sidewall, or to 35 psi (244 kPa), whichever is lower.

See the example below. When you end this high-speed driving, return to the cold inflation pressure shown on the Tire-Loading Information label. Example: You’ll find maximum load and inflation pressure molded on the tire’s sidewall, in small letters near the rim flange. It will read something like this: Maximum load 690 kg (1521 Ibs) @ 300 kPa (44 psi) Max. Press. For this example, you would set the inflation pressure for high-speed driving at 35 psi (244 kPa). 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:

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

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

Unusual wear Bad handling Rough ride Needless damage from road hazards

When to Check Check your tires once a month or more. Don’t forget your compact spare tire. It should be at 60 psi (420 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 keenin9 out dirt and moisture.

5-63

Check Tire Pressure System The check tire pressure system can alert you to a large change in the pressure of one tire. The system won’t alert you before you drive that a tire is low or flat. You must begin driving before the system will work properly. The CHECK TIRE PRESSURE message will appear on the Driver Information Center (DIC) or the system monitor TIRE PRESS light will come on if pressure difference (low pressure) is detected in one tire. The check tire pressure system may not alert you if:

more than one tire is low, the vehicle is moving faster than 65 mph (105 km/h), the system is not yet calibrated, the compact spare tire is installed, the tire treadwear is uneven, tire chains are being used, or the vehicle is being driven on a rough or frozen road.

5-64

If the anti-lock brake system warning light comes on, the check tire pressure system may not be working properly. See your dealer for service. Also, see Anti-Lock Brake System Warning Light on page 3-43. The check tire pressure system detects differences in tire rotation speeds that are caused by changes in tire pressure. The system can alert you about a low tire - but it doesn’t replace normal tire maintenance. See Tires on page 5-62. When the CHECK TIRE PRESSURE message appears on the Driver Information Center (DIC) or the systems monitor TIRE PRESS light comes on, you should stop as soon as you can and check all your tires for damage. If a tire is flat, see If a Tire Goes Flat on page 5-72. Also check the tire pressure in all four tires as soon as you can. See Inflation -- Tire Pressure on page 5-62. Any time you adjust a tire’s pressure or have one or more tires repaired or replaced, you’ll need to reset (calibrate) the check tire pressure system. You’ll also need to reset the system whenever you rotate the tires, buy new tires and install or remove the compact spare. Don’t reset the check tire pressure system without first correcting the cause of the problem and checking and adjusting the pressure in all four tires. If you reset the system when the tire pressures are incorrect, the check tire pressure system will not work properly and may not alert you when a tire is low or high.

The system Completes the calibration process during driving. Calibration time can take 45 to 90 minutes, depending on your driving habits. After the system has been calibrated, the system will alert the driver that a tire is low, up to a maximum speed of 65 mph (1 05 km/h).

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 Is Time for New Tires on page 5-67 and Wheel Replacement on page 5-69 for more information. Tne purpose oi reguiar rorarion is io acnieve more uniform wear for all tires on the vehicle. The first rotation is the most important. See “Part A: Scheduled Maintenance Services,” in Section 6, for scheduled rotation intervals.

5-65

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.

When rotating your tires, always use the correct rotation pattern shown here. Don’t include the compact spare tire in your tire rotation. After the tires have been rotated, adjust the front and rear inflation pressures as shown on the Tire-Loading Information label. Reset the check tire pressure system. See Check Tire Pressure System on page 5-64. Make certain that all wheel nuts are properly tightened. See “Wheel Nut Torque” under Capacities and Specifications on page 5- 100.

5-66

When It Is 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:

You can see the indicators at three or more places around the tire. YOU can see cord or tabric snowing tnrougn tne tire’s rubber. The tread or sidewall is cracked, cut or snagged deep enough to show cord or fabric.

The tire has a bump, bulge or split.

b The tire has a puncture, cut or other damage that

can’t be repaired well because of the size or location of the damage. Buying New Tires

To find out what kind and size of tires you need, look at the Tire-Loading Information label. The tires installed on your vehicle when it was new had a Tire Performance Criteria Specification (TPC Spec) number on each tire’s sidewall. When you get new tires, get ones with that same TPC Spec number. That way 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.

5-67

to lose control

Mixing tires couh :ause you 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, though. It was developed for use on your vehicle.

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.

5-68

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 (1.5) 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. Temperature - A, B, C The temperature grades are A (the highest), B, and C, representing the tire’s resistance to the generation i-ledf vvi-Iei-1 t&& ui ireai ar~d iis aLiiiiy iu dissip& 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.

5-69

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.

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 5-73 for more information. Used Replacement Wheels

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.

Putting a us 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.

Notice: If your vehicle has a tire size other than P235/55R17 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 front tires and tighten them as tightly as possible with the ends securely fastened. Drive slowiy 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.

Tire Chains

If your vehicle has P235/55R17 size tires, don’t use tire chains, 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 front tires.

Accessory Inflator

Notice: Don’t run your air inflator for longer than 30 minutes at one time. If you do, you may damage the system. The air inflator comes with a kit that includes a 20-foot (6.1 m) hose and an air pressure gage, as well as instructions and special adapters for inflating things like an air mattress or a basketball. 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.

-1

If your vehicle has an air inflator, it is located in the trunk. The air inflator will wo only with the ignition on.

Inflating something too much can make it explode, and you or others could be injured. Be sure to read the inflator instructions, and inflate any object only to its recommended pressure.

Pressing the AIR button will activate the inflator for ten minutes.

5-72

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 hazar ' varning flasl s.

Changing L h e can cause an 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:

y. ... 2

1. Set the parking brake firmly. 2. Put the shift lever in PARK (P). 3. Turn off the engine.

To be even more certain the vehicle won't move: you can put 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.

5-73

Removing the Spare Tire and Tools

5. Remove the wheel wrench, jack and the spare tire

from the trunk.

The equipment you’ll need is in the trunk.

1. Pull the carpeting from the floor of the trunk. 2. Remove the retainer, then lift and remove the cover. 3. Remove the compact spare tire. See Compact Spare Tire on page 5-81 for more information about the compact spare tire.

4. Unscrew the wing nuts to remove the container that

holds the wrench and jack.

The tools you’ll be using include the jack (A) and wheel wrench (B). Removing the Wheel Covers and Wheel Nut Caps If your vehicle has aluminum wheels and a center cover hides the wheel nuts, remove the center cover by using the flat end of the wrench to pry it off. Do not drop the cover or lay it face down, as it could become scratched or damaged. Do not use a hammer or mallet on this type of cover.

5-74

Removing the Flat Tire and Installing the Spare Tire

2. The jack has a bolt at the end. Attach the wheel

wrench to the bolt to create a jack handle.

1. Use the wheel wrench to loosen the wheel nuts, but

don't remove them.

3. Turn the wheel wrench counterclockwise to lower

the jack lift head until it fits under the vehicle.

5-75

I

4. Put the jack head into a notch in the frame which is

located near each wheel well. The front notch is 11 inches (28 cm) back from the front wheel well. The rear notch is 3.5 inches (9 cm) forward from the rear wheel well.

5-76

Getting under a vehicle when it is jacked up is 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.

Raising your vehicle with the ja improperly 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. Raise the vehicle by turning the wheel wrench clockwise. Raise the vehicle far enough off the ground so there is enough room for the compact spare tire to fit under the wheel well.

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

7. 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.

5-77

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

8. Place the compact spare tire on the wheel-mounting

surface.

9. Then reinstall the

wheel nuts with the rounded end of the nuts toward the wheel.

Make sure each wheel bolt is centered in each wheel hole while tightening the nuts. Tighten each nut by hand until the wheel is held against the hub.

5-78

10. Lower the vehicle by turning the wheel wrench counterclockwise. Lower the jack completely.

11. Tighten the wheel nuts

firmly in a crisscross sequence.

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.

12. Don’t try to put the wheel cover on the compact spare tire. It won’t fit. Store the wheel cover in the trunk until you have replaced the compact spare tire with a regular tire.

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.

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. When you reinstall the full size wheel and tire, you install the wheel cover or nut caps at this point. When reinstalling the nut caps on aluminum wheels, AI-- --_- -_..- ..,:&I- &L- ..,L--l llylllell tile Lapa a11uy v v l u I 11 I G V V I I G G I continue tightening one-quarter turn for plastic caps, or one-eighth turn for steel caps.

After you’ve put the compact spare tire on your vehicle, you’ll need to store the flat tire in your trunk. Store the flat tire as far forward in the trunk as possible. Store the jack and wheel wrench in their compartment in the trunk. For storage, the jack must be raised until the screw end is flush with the edge of the jack.

The compact spare tire 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 5-87. See the storing instructions label to return your compact spare tire into your trunk properly.

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 (105 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. You must: calibrate the Check Tire Pressure System after installing or removing the compact spare. See Check Tire Pressure System on page 5-64. 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 vehic!e 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 ether t!!hee!s spare tire and its wheel together. Nofice: 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:

Gasoline Benzene Naphtha Carbon Tetrachloride Acetone Paint Thinner Turpentine Lacquer Thinner Nail Polish Remover

They can all be hazardous - some more than others -and Don’t use any of these unless this manual says you can. In many uses, these will damage your vehicle:

they can all damage your vehicle, too.

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 5-88.

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.

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 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

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 5-88. 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.

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. 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.

For stubborn stains, use a leather cleaner. See your dealer for this product. 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.

5-84

Care of Safety Belts Keep belts clean and dry.

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 appiicaiiorl may ue required. See Fari E. %cur/////e/f&d Fluids and Lubricants on page 6-24. 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 5-88. 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. wearwg tmtmur L ~ I I I ~ W L ~ I I S ~ S 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 GM Vehicle Care/Appearance Materials on page 5-88. If 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 basecoatklearcoat 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.

5-86

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. Aluminum or Chrome-Plated Wheels Your vehicle may be equipped with either aluminum or chrome-plated 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. Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application. 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.

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.

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 everv sprinq, 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.

5-a7

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.

Vehicle Identification

Vehicle Identification Number (VIN)

SAMPLE4UXl M072675

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 your spare tire cover. 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.

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 1-55. Headlamp Wiring 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 neaaiamp system cneckea right away.

Windshield Wiper Fuses The windshield wiper motor is protected by an internal circuit breaker and a fuse. If the motor overheats due to heavy snow, etc., the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed. Power Windows and Other Power Options Circuit breakers in the rear fuse block 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.

5-91

Fuses and Circuit Breakers

Engine Compartment Fuse Block

The engine compartment fuse block is located in the front of the engine compartment on the passenger’s side. Lift the cover to gain access.

Fuse 22 or 23 can be moved to the outer position to enable the accessory power outlet or cigarette lighter when the ignition is not on. See your dealer for additional assistance, if needed.

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 damage 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. The MaxiFuses are located in two fuse blocks, one in the engine compartment and the other under the rear seat. If a MaxiFuse should blow, have your vehicle serviced by your dealer immediately. Removing Fuses You will find a fuse puller attached in both of the fuse blocks. Snap the wide end of the fuse puller on to the fuse, at the side indentations holding the puller and pull the fuse out.

Removing the Rear Seat Cushion

Notice: The battery and main fuse blocks are located under the rear seat cushion. The battery’s ground terminal and some relay wires are exposed. To help avoid damage to the battery and wires, be careful when removing or reinstalling the seat cushion. Do not remove covers from covered parts. Do not store anything under the seat, as objects could touch exposed wires and cause a short. To remove the rear seat cushion, do the following: 1. Pull up on the front of the cushion to release the

front hooks,

2. Pull the cushion up and out toward the front of the

vehicle.

To reinstall the rear seat cushion, do the following:

A safety belt tha sn’t properly roL.---. _hrough the seat cushion or is twisted won’t prowide the protection needed in a crash. If the safety belt hasn’t been routed through the seat cushion at all, it won’t be there to work for the next passenger. The person sitting in that position could be badly injured. After reinstalling the seat cushion, always check to be sure that the safety belts are properly routed and are not twisted.

Plan

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.

6-2

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.

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 Publications Ordering Information on page 7-9. “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 petform. “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 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 the different ways people use their vehicles, maintenance needs may vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have 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 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 on your vehicle’s Tire-Loading Information label. See Loading Your Vehicle on page 4-34. are driven on reasonable road surfaces within legal 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:

Follow the Short Trip/City Scheduled Maintenance if any one of these conditions is true for your vehicle: 0 Most trips are less than 5 miles (8 km). This is

particularly important when outside temperatures are below freezing.

0 Most trips include extensive idling (such as frequent

driving in stop-and-go traffic).

0 You frequently tow a trailer or use a carrier on top

of your vehicle.

0 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 TriplCity Intervals Every 3,000 Miles (5 000 km): Engine Oil and Filter Change (or 3 months, whichever occurs first). 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. Every 30,000 Miles (50 000 km): Engine Air Cleaner Filter Replacement. Supercharger Oil Check (or every 36 months, whichever occurs first) (3800 Code 1 V6 engine only). Every 50,000 Miles (83 000 km): Automatic Transaxle Service (severe conditions only). Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Automatic Transaxle Service (normal conditions). Every 150 000 Miles (240 000 km): Cooling System Service [nr every 60 months, whichever nccIJrs 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). Tire Rotation.

Every 30,000 Miles (50 000 km): Supercharger Oil Check (or every 36 months, whichever occurs first) (3800 Code 1 V6 engine only). Engine Air Cleaner Filter Replacement. Every 50,000 Miles (83 000 km): Automatic Transaxle Service (severe conditions only).

Every 100,000 Miles (166 000 km): Spark Plug Wire Inspection. Spark Plug Replacement. Automatic Transaxle Service (normal conditions). 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. Short Trip/City Scheduled Maintenance The services shown in this schedule up to 100,000 miles (1 66 000 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 Part B: Owner Checks and Services on page 6-18 and Part C: Periodic Maintenance Inspections on page 6-22.

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. *If your vehicle has the GM Oil Life SystemTM, a computer system lets you know when to change the oil and filter. This is based on engine revolutions and engine temperature and not on mileage. Based on driving conditions, the mileage at which an oil change will be indicated can vary considerably. For the oii life system to work properly, you must reset the system every time the oil is changed. When the system has calculated that oil life has been diminished, it will indicate that an oil change is necessary. An ENGINE OIL CHANGE SOON message will come on. Change your oil as soon as possible within the next two times you stop for fuel. It is possible that, if you are driving under the best conditions, the oil life system may not indicate that an oil change is necessary for over a year. However, your engine oil and filter must be changed at least once a year and at this time the system must be reset. It is also important to check your oil regularly and keep it at the proper level.

If the system is ever reset accidentally, you must
