2007 GMC Acadia Owners Manual

in which you or others could be injured. Always use the correct wheel, wheel bolts, and wheel nuts for replacement.

{CAUTION:

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

455

Tire Chains

{CAUTION:

Do not use tire chains. There is 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.

CAUTION:

(Continued)

CAUTION:

(Continued)

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 is contacting your vehicle, and do not spin your vehicle’s wheels. If you do find traction devices that will fit, install them on the front tires.

456

If a Tire Goes Flat It is unusual for a tire to blowout while you are driving, especially if you maintain your vehicle’s tires properly. If air goes out of a tire, it is 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 would 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.

{CAUTION:

Lifting a vehicle and getting under it to do maintenance or repairs is dangerous without the appropriate safety equipment and training. The jack provided with your vehicle is designed only for changing a flat tire. If it is used for anything else, you or others could be badly injured or killed if the vehicle slips off the jack. Use the jack provided with your vehicle only for changing a flat tire.

If a tire goes flat, the next part shows how to use the jacking equipment to change a flat tire safely.

457

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 vehicle’s hazard warning flashers. See Hazard Warning Flashers on page 172 for more information.

{CAUTION:

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

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

CAUTION:

(Continued)

CAUTION:

(Continued)

3. Turn off the engine and do not restart

while the vehicle is raised.

4. Do not allow passengers to remain in

the vehicle.

To be even more certain the vehicle will not move, you should 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, at the opposite end of the vehicle.

When your vehicle has a flat tire, use the following example as a guide to assist you in the placement of wheel blocks.

458

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

5. Tilt the retainer and slip it through the wheel

opening to remove the spare tire from the cable.

6. Turn the wrench clockwise to raise the cable

back up after removing the spare tire. Do not store a full-size or a flat road tire under the vehicle. See Storing a Flat or Spare Tire and Tools on page 472.

461

To continue changing the flat tire, see Removing the Flat Tire and Installing the Spare Tire on page 463.

If the spare tire will not lower, the secondary latch could be engaged.

462

Do the following to check the cable: 1. Check under the vehicle to see if the cable is

visible.

2. If it is not visible, see Secondary Latch

System on page 468. If it is visible, first try to tighten the cable by turning the lug wrench clockwise until you hear two clicks or feel it skip twice. You cannot over-tighten the cable.

3. Loosen the cable by turning the wrench

counterclockwise three or four turns.

4. If the spare tire has not lowered, tighten the cable all the way and then loosen it at least two times. If the spare tire did lower to the ground, continue with Step 5 under “Removing the Spare Tire (Vehicles with the Rear Convenience Center)” listed previously.

5. If you still cannot lower the spare tire to the

ground, see Secondary Latch System on page 468.

Removing the Flat Tire and Installing the Spare Tire 1. It is recommended that you do a safety check

before preceding. See Changing a Flat Tire on page 458 for more information.

2. If the vehicle has a wheel cover, loosen the

plastic nut caps with the wheel wrench. They will not come off. Then, using the flat end of the wheel wrench, pry along the edge of the cover until it comes off. Be careful; the edges may be sharp. Do not try to remove the cover with your bare hands. Store the wheel cover securely in the rear of the vehicle until you have the flat tire repaired or replaced. If your vehicle has aluminum wheels, remove the wheel nut caps using the wheel wrench.

3. Loosen the wheel nuts — but do not

remove them — using the lug wrench. For wheels with a wheel lock key, use the wheel lock key between the lock nut and lug wrench. The key is supplied in the front passenger door pocket.

If your vehicle has wheel locks and an

Notice: impact wrench is used to remove the wheel nuts, the lock nut or wheel lock key could be damaged. Do not use an impact wrench to remove the wheel nuts if your vehicle has wheel locks.

463

Notice: If a jack is used to raise the vehicle without positioning it correctly, your vehicle could be damaged. When raising your vehicle on a jack, avoid contact with the rear axle control arms. 5. Do not raise the vehicle yet. Put the compact

spare tire near you.

{CAUTION:

4. To identify the appropriate jacking location, find the triangle about 12 inches (30.5 cm) from the front tire or about 10.5 inches (27 cm) from the rear tire.

The triangle is located near each wheel on the vehicle’s exterior.

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.

464

{CAUTION:

Raising your vehicle with the jack 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.

6. Attach the lug wrench to the jack, and turn the wrench clockwise to raise the jack head 3 inches (7.6 cm).

7. Place the jack under the vehicle as identified

in Step 3. Raise the vehicle by turning the lug wrench clockwise in the jack. Raise the vehicle far enough off the ground so that there is enough room for the spare tire to fit under the wheel well.

8. Remove all the wheel nuts and take off the

flat tire.

9. Remove the plastic spare tire heat shield by

pulling the rubber latch. Store the plastic spare tire heat shield. See Storing a Flat or Spare Tire and Tools on page 472 for more information.

465

{CAUTION:

{CAUTION:

Rust or dirt on the wheel, or on the parts to which it is fastened, can make the wheel nuts become loose after time. The wheel could come off and cause an accident. When changing a wheel, remove any rust or dirt from the places where the wheel attaches to the vehicle. In an emergency, a cloth or a paper towel can be used to do this; but be sure to use a scraper or wire brush later, if needed, to get all the rust or dirt off.

Never use oil or grease on studs or nuts. Because the nuts might come loose. The vehicle’s wheel could fall off, causing a serious accident.

10. Remove any rust or dirt from the wheel bolts, mounting surfaces, and spare wheel.

11. Install the compact spare tire. 12. Lower the vehicle by attaching the lug wrench

to the jack and turning the wrench counterclockwise. Lower the jack completely.

466

{CAUTION:

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 on page 497 for wheel nut torque specification.

Improperly tightened wheel nuts can

Notice: 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 on page 497
for the wheel nut torque specification.

13. Tighten the wheel

nuts firmly in a crisscross sequence, as shown.

Notice: Wheel covers will not fit on your vehicle’s compact spare. If you try to put a wheel cover on the compact spare, the cover or the spare could be damaged.

467

Secondary Latch System Your vehicle has an underbody mounted tire hoist assembly that has a secondary latch system. It is designed to stop the compact spare tire from suddenly falling off your vehicle if the cable holding the spare tire is damaged. For the secondary latch to work, the tire must be stowed with the valve stem pointing down. See Storing a Flat or Spare Tire and Tools on page 472 for instructions on storing the spare tire correctly.

{CAUTION:

Before beginning this procedure read all the instructions. Failure to read and follow the instructions could damage the hoist assembly and you and others could get hurt. Read and follow the instructions listed next.

468

To release the spare tire from the secondary latch:

{CAUTION:

Someone standing too close during the procedure could be injured by the jack. If the spare tire does not slide off the jack completely, make sure no one is behind you or on either side of you as you pull the jack out from the under spare.

1. If the cable is not visible, start this procedure

at Step 3.

8. Disconnect the lug wrench from the jack and

carefully remove the jack. Use one hand to push against the spare tire while firmly pulling the jack out from under the spare tire with the other hand.

9. Tilt the retainer and slip it through the wheel

opening when the spare tire has been completely lowered.

10. Turn the lug wrench clockwise to raise the

cable back up if the cable is hanging.

Have the hoist assembly inspected as soon as you can. You will not be able to store a spare tire using the hoist assembly until it has been repaired or replaced.

471

Storing a Flat or Spare Tire and Tools Storing the Spare Tire

{CAUTION:

The underbody-mounted spare tire needs to be stored with the valve stem pointing down. If the spare tire is stored with the valve stem pointing upwards, its secondary latch will not work properly and the spare tire could loosen and suddenly fall from your vehicle. If this happened when your vehicle was being driven, the tire might contact a person or another vehicle, causing injury and, of course, damage to itself as well. Be sure the underbody-mounted spare tire is stored with its valve stem pointing down.

472

{CAUTION:

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

To store the spare tire: 1. Lay the compact spare tire near the rear of

the vehicle with the valve stem down.

2. Reinstall the plastic spare tire heat shield on

the compact spare tire.

3. If the vehicle has aluminum wheels, remove the small center cap by tapping the back of the cap with the extension of the shaft.

4. Slide the cable retainer through the center of

the wheel and start to raise the compact spare tire. Make sure the retainer is fully seated across the underside of the wheel.

5. When the compact spare tire is almost in the

stored position, turn the tire so the valve is toward the rear of the vehicle. This position helps when checking the air pressure in the compact spare tire.

6. Raise the tire fully against the underside of the vehicle. Continue turning the lug wrench until you feel more than two clicks. This indicates that the compact spare tire is secure and the cable is tight. The spare tire hoist cannot be overtightened.

7. Make sure the tire is stored securely. Push,

pull (A), and then try to turn (B) the tire. If the tire moves, use the lug wrench to tighten the cable.

473

Storing the Flat Tire Notice: Storing the full-size flat tire in the underbody hoist system can expose it to heat from the exhaust system. This can damage the tire and underbody hoist system. Do not store the full-size flat tire in the underbody hoist system. 1. Remove the cable package from the jack

storage area.

2. Remove the small center cap by tapping the

back of the cap with the extension of the shaft, if the vehicle has aluminum wheels.

3. Put the flat tire in the rear storage area with

the valve stem pointing toward the rear of the vehicle.

474

4. Hook on end of the cable onto the outside

portion of the liftgate hinge opposite (B).

5. Pull the cable (A) through the door striker (E),

the center of the wheel (D), and the plastic spare tire heat shield (C), as shown.

6. Hook the other end

of the cable onto the outside portion of the liftgate hinge (B).

9. Push the tube

toward the front of the vehicle.

7. Pull on the cable to make sure it is secure.

8. Make sure the metal tube is centered at

the striker.

10. Close the liftgate and make sure it is latched

properly.

475

Storing the Tools

A. Tool Bag B. Wing Bolt C. Jack

476

Put back all tools as they were stored in the jack storage compartment and put the compartment cover back on. 1. Make that the bottom of the jack is facing

toward you.

2. Turn the jack (C) on its side and place it down

on the holding bracket.

3. Reinstall the wing bolt (B) by turning it

clockwise.

4. To replace the cover, line up the tabs on the bottom of the cover with the slots in the cover opening. Push the cover in place, insuring that the upper front and rear tabs are in the opening and push the cover closed. Make sure that the center latch is fully engaged. This secures the cover in place.

Store the center cap or the plastic bolt-on wheel covers until a full size tire is put back on the vehicle. When you replace the compact spare with a full-size tire, reinstall the bolt-on wheel covers or the center cap. Hand-tighten them over the wheel nuts, using the lug wrench.

Compact Spare Tire Although the compact spare tire was fully inflated when the vehicle was new, it can lose air after a time. Check the inflation pressure regularly. It should be 60 psi (420 kPa). After installing the compact spare on the vehicle, stop as soon as possible and make sure the 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 the full-size tire repaired or replaced at your convenience. Of course, it is best to replace the spare with a full-size tire as soon as possible. The spare tire will last longer and be in good shape in case it is needed again.

Notice: When the compact spare is installed, do not take your vehicle through an automatic car wash with guide rails. The compact spare can get caught on the rails. That can damage the tire and wheel, and maybe other parts of your vehicle. Do not use the compact spare on other vehicles. And do not mix the compact spare tire or wheel with other wheels or tires. They will not fit. Keep the spare tire and its wheel together. The All-Wheel Drive (AWD) system will be automatically disabled when you use the compact spare. To restore the AWD and prevent excessive wear on the clutch in your AWD, replace the compact spare tire with a full-size tire as soon as possible. Notice: Tire chains will not fit your compact spare. Using them can damage your vehicle and can damage the chains too. Do not use tire chains on your compact spare.

477

Appearance Care

Cleaning the Inside of Your Vehicle Your vehicle’s interior will continue to look its best if it is cleaned often. Although not always visible, dust and dirt can accumulate on your upholstery. Dirt can damage carpet, fabric, leather, and plastic surfaces. Regular vacuuming is recommended to remove particles from your upholstery. It is important to keep your upholstery from becoming and remaining heavily soiled. Soils should be removed as quickly as possible. Your vehicle’s interior may experience extremes of heat that could cause stains to set rapidly. Lighter colored interiors may require more frequent cleaning. Use care because newspapers and garments that transfer color to your home furnishings may also transfer color to your vehicle’s interior.

If you use abrasive cleaners when

When cleaning your vehicle’s interior, only use cleaners specifically designed for the surfaces being cleaned. Permanent damage may result from using cleaners on surfaces for which they were not intended. Use glass cleaner only on glass. Remove any accidental over-spray from other surfaces immediately. To prevent over-spray, apply cleaner directly to the cleaning cloth. Notice: cleaning glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner. Many cleaners contain solvents that may become concentrated in your vehicle’s breathing space. Before using cleaners, read and adhere to all safety instructions on the label. While cleaning your vehicle’s interior, maintain adequate ventilation by opening your vehicle’s doors and windows.

478

Dust may be removed from small buttons and knobs using a small brush with soft bristles. Your dealer/retailer has a product for cleaning your vehicle’s glass. Should it become necessary, you can also obtain a product from your dealer/retailer to remove odors from your vehicle’s upholstery. Do not clean your vehicle using the following cleaners or techniques: (cid:129) Never use a knife or any other sharp object to

remove a soil from any interior surface.

(cid:129) Never use a stiff brush. It can cause damage

to your vehicle’s interior surfaces. (cid:129) Never apply heavy pressure or rub

aggressively with a cleaning cloth. Use of heavy pressure can damage your interior and does not improve the effectiveness of soil removal.

(cid:129) Use only mild, neutral-pH soaps. Avoid laundry

detergents or dishwashing soaps with degreasers. Using too much soap will leave a residue that leaves streaks and attracts dirt. For liquid cleaners, about 20 drops per gallon (3.78 L) of water is a good guide.

(cid:129) Do not heavily saturate your upholstery while

cleaning.

(cid:129) Damage to your vehicle’s interior may result

from the use of many organic solvents such as naptha, alcohol, etc.

479

Fabric/Carpet Use a vacuum cleaner with a soft brush attachment frequently to remove dust and loose dirt. A canister vacuum with a beater bar in the nozzle may only be used on floor carpet and carpeted floor mats. For soils, always try to remove them first with plain water or club soda. Before cleaning, gently remove as much of the soil as possible using one of the following techniques: (cid:129) For liquids: gently blot the remaining soil

with a paper towel. Allow the soil to absorb into the paper towel until no more can be removed.

(cid:129) For solid dry soils: remove as much as

possible and then vacuum.

To clean, use the following instructions: 1. Saturate a lint-free, clean white cloth with

water or club soda.

2. Wring the cloth to remove excess moisture. 3. Start on the outside edge of the soil and gently

rub toward the center. Continue cleaning, using a clean area of the cloth each time it becomes soiled.

4. Continue to gently rub the soiled area until the

cleaning cloth remains clean.

5. If the soil is not completely removed, use a mild soap solution and repeat the cleaning process that was used with plain water.

If any of the soil remains, a commercial fabric cleaner or spot lifter may be necessary. When a commercial upholstery cleaner or spot lifter is to be used, test a small hidden area for colorfastness first. If the locally cleaned area gives any impression that a ring formation may result, clean the entire surface. After the cleaning process has been completed, a paper towel can be used to blot excess moisture from the fabric or carpet.

480

Leather A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a soft cloth dampened with a mild soap solution can be used. Allow the leather to dry naturally. Do not use heat to dry. Never use steam to clean leather. Never use spot lifters or spot removers on leather. Many commercial leather cleaners and coatings that are sold to preserve and protect leather may permanently change the appearance and feel of your leather and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Never use shoe polish on your leather.

Instrument Panel, Vinyl, and Other Plastic Surfaces A soft cloth dampened with water may be used to remove dust. If a more thorough cleaning is necessary, a clean soft cloth dampened with a mild soap solution can be used to gently remove dust and dirt. Never use spot lifters or removers on plastic surfaces. Many commercial cleaners and coatings that are sold to preserve and protect soft plastic surfaces may permanently change the appearance and feel of your interior and are not recommended. Do not use silicone or wax-based products, or those containing organic solvents to clean your vehicle’s interior because they can alter the appearance by increasing the gloss in a non-uniform manner. Some commercial products may increase gloss on your instrument panel. The increase in gloss may cause annoying reflections in the windshield and even make it difficult to see through the windshield under certain conditions.

481

Care of Safety Belts Keep belts clean and dry.

{CAUTION:

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

Weatherstrips Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather frequent application may be required. See Recommended Fluids and Lubricants on page 511.

Washing Your Vehicle The paint finish on the vehicle provides beauty, depth of color, gloss retention, and durability. The best way to preserve the vehicle’s finish is to keep it clean by washing it often with lukewarm or cold water. Do not wash the vehicle in the direct rays of the sun. Use a car washing soap. Do not use strong soaps or chemical detergents. Be sure to rinse the vehicle well, removing all soap residue completely. Approved cleaning products can be obtained from your dealer/retailer. See Vehicle Care/Appearance Materials on page 487. Do not 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. Avoid using hard brushes during cleaning. It may damage your vehicle’s finish. 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 the vehicle. Avoid using high pressure washes closer than 12 inches (30 cm) to the surface of the vehicle.

482

Cleaning Exterior Lamps/Lenses Use only lukewarm or cold water, a soft cloth and a car washing soap to clean exterior lamps and lenses. Follow instructions under Washing Your Vehicle on page 482.

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 approved cleaning products from your dealer/retailer. See Vehicle Care/Appearance Materials on page 487. If your vehicle has a basecoat/clearcoat paint finish, the clearcoat gives more depth and gloss to the colored basecoat. Always use waxes and polishes that are non-abrasive and made for a basecoat/clearcoat paint finish. Notice: Machine compounding or aggressive polishing on a basecoat/clearcoat paint finish may damage it. Use only non-abrasive waxes and polishes that are made for a basecoat/clearcoat paint finish on your vehicle.

Foreign materials such as calcium chloride and other salts, ice melting agents, road oil and tar, tree sap, bird droppings, chemicals from industrial chimneys, etc., can damage your vehicle’s finish if they remain on painted surfaces. Wash the vehicle as soon as possible. If necessary, use non-abrasive cleaners that are marked safe for painted surfaces to remove foreign matter. Exterior painted surfaces are subject to aging, weather and chemical fallout that can take their toll over a period of years. You can help to keep the paint finish looking new by keeping your vehicle garaged or covered whenever possible. Protecting Exterior Bright Metal Parts Bright metal parts should be cleaned regularly to keep their luster. Washing with water is all that is usually needed. However, you may use chrome polish on chrome or stainless steel trim, if necessary. Use special care with aluminum trim. To avoid damaging protective trim, never use auto or chrome polish, steam or caustic soap to clean aluminum. A coating of wax, rubbed to high polish, is recommended for all bright metal parts.

483

Windshield, Backglass, and Wiper Blades Clean the outside of the windshield and backglass with glass cleaner. Clean the rubber blades using a lint free cloth or paper towel soaked with windshield washer fluid or a mild detergent. Wash the windshield thoroughly when you clean the blades. Bugs, road grime, sap and a buildup of vehicle wash/wax treatments may cause wiper streaking. Replace the wiper blades if they are worn or damaged. Wipers can be damaged by: (cid:129) Extreme dusty conditions (cid:129) Sand and salt (cid:129) Heat and sun (cid:129) Snow and ice, without proper removal

Aluminum or Chrome-Plated Wheels and Trim Your vehicle may have either aluminum or chrome-plated wheels. Keep the 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. Notice: Chrome wheels and other chrome trim may be damaged if you do not wash your vehicle after driving on roads that have been sprayed with magnesium, calcium or sodium chloride. These chlorides are used on roads for conditions such as ice and dust. Always wash your vehicle’s chrome with soap and water after exposure.

484

If you use strong soaps, chemicals,

Notice: abrasive polishes, cleaners, brushes, or cleaners that contain acid on aluminum or chrome-plated wheels, you could damage the surface of the wheel(s). The repairs would not be covered by your warranty. Use only approved cleaners on aluminum or chrome-plated wheels. The surface of these wheels is similar to the painted surface of your vehicle. Do not 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. Notice: Using chrome polish on aluminum wheels could damage the wheels. The repairs would not be covered by your warranty. Use chrome polish on chrome wheels only. Use chrome polish only on chrome-plated wheels, but avoid any painted surface of the wheel, and buff off immediately after application.

Notice: If you drive your vehicle through an automatic car wash that has silicone carbide tire cleaning brushes, you could damage the aluminum or chrome-plated wheels. The repairs would not be covered by your warranty. Never drive a vehicle equipped with aluminum or chrome-plated wheels through an automatic car wash that uses silicone carbide tire cleaning brushes.

Tires To clean the tires, use a stiff brush with tire cleaner. Notice: Using petroleum-based tire dressing products on your vehicle may damage the paint finish and/or tires. When applying a tire dressing, always wipe off any overspray from all painted surfaces on your vehicle.

485

Sheet Metal Damage If the 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 available from your dealer/ retailer. Larger areas of finish damage can be corrected in your dealer’s/retailer’s body and paint shop.

486

Underbody Maintenance Chemicals used for ice and snow removal and dust control can collect on the underbody. If these are not removed, corrosion and rust can develop on the underbody parts such as fuel lines, frame, floor pan, and exhaust system even though they have corrosion protection. At least every spring, flush these materials from the underbody with plain water. Clean any areas where mud and debris can collect. Dirt packed in close areas of the frame should be loosened before being flushed. Your dealer/retailer or an underbody car washing system can do this for you. Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on the vehicle. This damage can take two forms: blotchy, ring-shaped discolorations, and small, irregular dark spots etched into the paint surface. Although no defect in the paint job causes this, we 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)

This is the legal identifier for your vehicle. It appears on a plate in the front corner of the instrument panel, on the driver side. You can see it if you look through the windshield from outside your vehicle. The VIN also appears on the Certification/Tire and Service Parts labels and the certificates of title and registration.

Engine Identification The eighth character in the VIN is the engine code. This code helps you identify your vehicle’s engine, specifications, and replacement parts.

Service Parts Identification Label This label is on the inside of the glove box. It is very helpful if you ever need to order parts. The label has the following information: (cid:129) Vehicle Identification Number (VIN) (cid:129) Model designation (cid:129) Paint information (cid:129) Production options and special equipment Do not remove this label from the vehicle.

488

Electrical System

High Voltage Devices and Wiring

{CAUTION:

Exposure to high voltage can cause shock, burns, and even death. The high voltage systems in your vehicle can only be serviced by technicians with special training. High voltage devices are identified by labels. Do not remove, open, take apart, or modify these devices. High voltage cable or wiring has orange covering. Do not probe, tamper with, cut, or modify high voltage cable or wiring.

Add-On Electrical Equipment Notice: Do not add anything electrical to your vehicle unless you check with your dealer/retailer first. Some electrical equipment can damage your vehicle and the damage would not be covered by your warranty. Some add-on electrical equipment can keep other components from working as they should. Add-on equipment can drain your vehicle’s battery, even if your vehicle is not operating. Your vehicle has an airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 90.

Look at the silver-colored band inside the fuse. If the band is broken or melted, replace the fuse. Be sure you replace a bad fuse with a new one of the identical size and rating. If you ever have a problem on the road and do not have a spare fuse, you can borrow one that has the same amperage. Just pick some feature of your vehicle that you can get along without, like the radio or cigarette lighter, and use its fuse if it is the correct amperage. Replace it as soon as you can.

Instrument Panel Fuse Block The instrument panel fuse block is located under the instrument panel on the passenger side of the vehicle. Pull down on the cover to access the fuse block.

Windshield Wiper Fuses The windshield wiper motor is protected by a circuit breaker and a fuse. If the motor overheats due to heavy snow or ice, the wiper will stop until the motor cools. If the overload is caused by some electrical problem, have it fixed.

Power Windows and Other Power Options Circuit breakers in the fuse panel protect the power windows and other power accessories. When the current load is too heavy, the circuit breaker opens and closes, protecting the circuit until the problem is fixed.

Fuses and Circuit Breakers The wiring circuits in your vehicle are protected from short circuits by a combination of fuses, circuit breakers and fusible thermal links. This greatly reduces the chance of fires caused by electrical problems.

Maintenance Schedule

Introduction Important: Keep engine oil at the proper level and change as recommended.

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

Maintenance Requirements Notice: Maintenance intervals, checks, inspections, replacement parts, 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 scheduled maintenance might not be covered by warranty.

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 is 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, be sure to maintain your vehicle properly.

500

Using the Maintenance Schedule We want to help you keep your vehicle in good working condition. But we do not know exactly how you will drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands, or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your dealer/retailer. This schedule is for vehicles that:

carry passengers and cargo within recommended limits. You will find these limits on the Tire and Loading Information label. See Loading Your Vehicle on page 361. are driven on reasonable road surfaces within legal driving limits. use the recommended fuel. See Gasoline Octane on page 388.

The services in Scheduled Maintenance on page 502 should be performed when indicated. See Additional Required Services on page 504 and Maintenance Footnotes on page 506 for further information.

{CAUTION:

Performing maintenance work on a vehicle can be dangerous. In trying to do some jobs, you can be seriously injured. Do your own maintenance work only if you have the required know-how and the proper tools and equipment for the job. If you have any doubt, see your dealer/retailer to have a qualified technician do the work. See Doing Your Own Service Work on page 386.

Some maintenance services can be complex. So, unless you are technically qualified and have the necessary equipment, you should have your dealer/retailer do these jobs.

501

(cid:129) (cid:129) (cid:129) When you go to your dealer/retailer for your service needs, you will know that trained and supported service technicians will perform the work using genuine parts. If you want to purchase service information, see Service Publications Ordering Information on page 535. Owner Checks and Services on page 507 tells you what should be checked, when to check it, and what you can easily do to help keep your vehicle in good condition. The proper replacement parts, fluids, and lubricants to use are listed in Recommended Fluids and Lubricants on page 511 and Normal Maintenance Replacement Parts on page 512. When your vehicle is serviced, make sure these are used. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. We recommend the use of genuine parts from your dealer/retailer.

Scheduled Maintenance When the CHANGE ENGINE OIL SOON message comes on, it means that service is required for your vehicle. Have your vehicle serviced as soon as possible within the next 600 miles (1 000 km). It is possible that, if you are driving under the best conditions, the engine oil life system might not indicate that vehicle service is necessary for over a year. However, the engine oil and filter must be changed at least once a year and at this time the system must be reset. Your dealer/retailer has trained service technicians who will perform this work using genuine parts and reset the system. If the engine oil life system is ever reset accidentally, you must service your vehicle within 3,000 miles (5 000 km) since your last service. Remember to reset the oil life system whenever the oil is changed. See Engine Oil Life System on page 400 for information on the Engine Oil Life System and resetting the system.

502

When the CHANGE ENGINE OIL SOON message appears, certain services, checks, and inspections are required. Required services are described in the following for “Maintenance I” and “Maintenance II.” Generally, it is recommended that your first service be Maintenance I, your second service be Maintenance II, and that you alternate Maintenance I and Maintenance II thereafter. However, in some cases, Maintenance II may be required more often.

Maintenance I — Use Maintenance I if the CHANGE ENGINE OIL SOON message comes on within 10 months since the vehicle was purchased or Maintenance II was performed. Maintenance II — Use Maintenance II if the previous service performed was Maintenance I. Always use Maintenance II whenever the message comes on 10 months or more since the last service or if the message has not come on at all for one year.

Maintenance Footnotes (a) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including calipers, parking brake, etc. Check parking brake adjustment. (b) Visually inspect front and rear suspension and steering system for damaged, loose, or missing parts or signs of wear. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. (c) Visually inspect hoses and have them replaced if they are cracked, swollen, or deteriorated. Inspect all pipes, fittings and clamps; replace with genuine parts as needed. To help ensure proper operation, a pressure test of the cooling system and pressure cap and cleaning the outside of the radiator and air conditioning condenser is recommended at least once a year.

506

(d) Inspect wiper blades for wear, cracking, or contamination. Clean the windshield and wiper blades, if contaminated. Replace wiper blades that are worn or damaged. See Windshield Wiper Blade Replacement on page 434 and Windshield, Backglass, and Wiper Blades on page 484 for more information. (e) Make sure the safety belt reminder light and all belts, buckles, latch plates, retractors, and anchorages are working properly. Look for any other loose or damaged safety belt system parts. If you see anything that might keep a safety belt system from doing its job, have it repaired. Have any torn or frayed safety belts replaced. Also look for any opened or broken airbag coverings, and have them repaired or replaced. The airbag system does not need regular maintenance. (f) Lubricate all key lock cylinders, hood latch assemblies, secondary latches, pivots, spring anchor and release pawl, hood and door hinges, rear folding seats, and liftgate hinges. More frequent lubrication may be required when exposed to a corrosive environment. Applying silicone grease on weatherstrips with a clean cloth will make them last longer, seal better, and not stick or squeak.

(g) A fluid loss in any vehicle system could indicate a problem. Have the system inspected and repaired and the fluid level checked. Add fluid if needed. (h) Change automatic transmission fluid if the vehicle is mainly driven under one or more of these conditions:

− In heavy city traffic where the outside

temperature regularly reaches 90°F (32°C) or higher.

− In hilly or mountainous terrain. − When doing frequent trailer towing. − Uses such as found in taxi, police, or

delivery service.

(i) Drain, flush, and refill cooling system. This service can be complex; you should have your dealer/retailer perform this service. See Engine Coolant on page 406 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap, and filler neck. Pressure test the cooling system and pressure cap.

(j) Check system for interference or binding and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do not lubricate accelerator or cruise control cables. (k) Visually inspect belt for fraying, excessive cracks, or obvious damage. Replace belt if necessary. (l) If you drive regularly under dusty conditions, inspect the filter at each engine oil change.

Owner Checks and Services These owner checks and services should be performed at the intervals specified to help ensure the safety, dependability, and emission control performance of your vehicle. Your dealer/retailer can assist you with these checks and services. Be sure any necessary repairs are completed at once. Whenever any fluids or lubricants are added to your vehicle, make sure they are the proper ones, as shown in Recommended Fluids and Lubricants on page 511.

507

At Least Once a Month Tire Inflation Check Inspect your vehicle’s tires and make sure they are inflated to the correct pressures. Do not forget to check the spare tire. See Inflation - Tire Pressure on page 442. Check to make sure the spare tire is stored securely. See Changing a Flat Tire on page 458. Tire Wear Inspection Tire rotation may be required for high mileage highway drivers prior to the Engine Oil Life System service notification. Check the tires for wear and, if necessary, rotate the tires. See Tire Inspection and Rotation on page 448.

It is important to check the engine oil

At Each Fuel Fill It is important to perform these underhood checks at each fuel fill. Engine Oil Level Check Check the engine oil level and add the proper oil if necessary. See Engine Oil on page 397 for further details. Notice: regularly and keep it at the proper level. Failure to keep the engine oil at the proper level can cause damage to the engine not covered by your warranty. Engine Coolant Level Check Check the engine coolant level and add DEX-COOL® coolant mixture if necessary. See Engine Coolant on page 406 for further details. Windshield Washer Fluid Level Check Check the windshield washer fluid level in the windshield washer fluid reservoir and add the proper fluid if necessary.

508

At Least Once a Year Starter Switch Check

{CAUTION:

When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured.

1. Before you start, be sure you have enough

room around the vehicle.

2. Firmly apply both the parking brake and the

regular brake. See Parking Brake on page 134. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts.

3. Try to start the engine in each gear. The vehicle should start only in PARK (P) or NEUTRAL (N). If the vehicle starts in any other position, contact your dealer/retailer for service.

Automatic Transmission Shift Lock Control System Check

{CAUTION:

When you are doing this inspection, the vehicle could move suddenly. If the vehicle moves, you or others could be injured.

1. Before you start, be sure you have enough

room around the vehicle. It should be parked on a level surface.

2. Firmly apply the parking brake. See Parking

Brake on page 134. Be ready to apply the regular brake immediately if the vehicle begins to move. 3. With the engine off, turn the ignition to ON,

but do not start the engine. Without applying the regular brake, try to move the shift lever out of PARK (P) with normal effort. If the shift lever moves out of PARK (P), contact your dealer/retailer for service.

509

Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake. (cid:129) To check the parking brake’s holding ability:

With the engine running and the transmission in NEUTRAL (N), slowly remove foot pressure from the regular brake pedal. Do this until the vehicle is held by the parking brake only.

(cid:129) To check the PARK (P) mechanism’s holding

ability: With the engine running, shift to PARK (P). Then release the parking brake followed by the regular brake.

Contact your dealer/retailer if service is required. Underbody Flushing Service At least every spring, use plain water to flush any corrosive materials from the underbody. Take care to clean thoroughly any areas where mud and other debris can collect.

Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn the ignition to OFF in each shift lever position. (cid:129) The ignition should turn to OFF only when the

shift lever is in PARK (P).

(cid:129) The ignition key should come out only in OFF. Contact your dealer/retailer if service is required. Parking Brake and Automatic Transmission Park (P) Mechanism Check

{CAUTION:

When you are doing this check, your vehicle could begin to move. You or others could be injured and property could be damaged. Make sure there is room in front of your vehicle in case it begins to roll. Be ready to apply the regular brake at once should the vehicle begin to move.
