clean the entire area immediately or it will set.

(cid:127) (cid:127) (cid:127) (cid:127) Most stains can be removed with club soda water. To clean, use the following instructions: 1. For liquids: blot with a clean, soft, white cloth.

For solids: remove as much as possible and then vacuum or brush.

2. Apply club soda water to a clean, soft, white cloth.

Do not over-saturate; the cloth should not drip water.

3. Clean the entire area. Avoid getting the fabric

too wet.

4. Start cleaning from the seams into the stain

to avoid a ring effect.

5. Continue cleaning, using a clean area of the

cloth each time it becomes soiled.

6. When the stain is removed, blot the cleaned

area with another dry, clean, soft, white cloth.

Using Cleaner on Fabric 1. First, try the cleaner on an area of the fabric that is not easily seen to make sure the cleaner does not affect the color of the fabric.

2. For liquids: blot with a clean, soft, white cloth.

For solids: remove as much as possible and then vacuum or brush.

3. Spray a small amount of the cleaner onto a clean soft, white, cloth. Do not apply spray directly to the fabric.

4. Start cleaning from the seams into the stain to

avoid a ring effect.

5. Continue cleaning, using a clean area of the cloth

each time it becomes soiled.

6. When the stain is removed, blot the cleaned area

with another dry, clean, soft, white cloth.

7. If the cleaner leaves a ring effect, follow up with the

club soda water instructions given earlier in this section.

Special Fabric Cleaning Problems Stains caused by such things as catsup, black coffee, egg, fruit, fruit juice, milk, soft drinks, vomit, urine, and blood can be removed using the club soda water instructions given earlier in this section. If an odor lingers after cleaning vomit or urine, treat the area with a water and baking soda solution: 1 teaspoon (5 ml) of baking soda to 1 cup (250 ml) of lukewarm water. Let dry.

5-119

(cid:127) Soiled or stained leather should be cleaned

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

Instrument Panel Use only mild soap and water to clean the top surfaces of the instrument panel. Sprays containing silicones or waxes may cause annoying reﬂections in the windshield and even make it difficult to see through the windshield under certain conditions.

Interior Plastic Components Use only a mild soap and water solution on a soft cloth or sponge. Commercial cleaners may affect the surface ﬁnish.

Stains caused by oil and grease can be cleaned with an approved GM cleaner and a clean, white cloth. 1. Carefully scrape off excess stain. 2. Clean with cool water and allow to dry completely. 3. If a stain remains, follow the “Using Cleaner on

Fabric” instructions described earlier.

Vinyl Use warm water and a clean cloth. (cid:127) Rub with a clean, damp cloth to remove dirt. This may have to be done more than once. Things like tar, asphalt, and shoe polish will stain if they are not removed quickly. Use a clean cloth and vinyl 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.

(cid:127) Never use oils, varnishes, solvent-based or abrasive cleaners, furniture polish, or shoe polish on leather.

5-120

(cid:127) (cid:127) 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 Vehicle Care/Appearance Materials on page 5-125. Notice: glass surfaces on your vehicle, you could scratch the glass and/or cause damage to the rear window defogger and the integrated radio antenna. When cleaning the glass on your vehicle, use only a soft cloth and glass cleaner.

If you use abrasive cleaners when cleaning

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 6-13.

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. GM-approved cleaning products can be obtained from your dealer. See Vehicle Care/Appearance Materials on page 5-125. 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. 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.

5-121

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 5-121.

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 Vehicle Care/Appearance Materials on page 5-125. 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.

5-122

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 glass cleaning liquid or powder and water solution. The windshield is clean if beads do not form when it is rinsed 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 The vehicle may be equipped with 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.

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 GM-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.

5-123

If you drive your vehicle through an

Notice: 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. Do not 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 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.

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 GM dealer. Larger areas of ﬁnish damage can be corrected in your GM dealer’s body and paint shop.

5-124

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 GM dealer or an underbody car washing system can do this for you.

Chemical Paint Spotting Some weather and atmospheric conditions can create a chemical fallout. Airborne pollutants can fall upon and attack painted surfaces on 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, 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 Number (VIN)

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

5-126

Engine Identiﬁcation The eighth 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 will ﬁnd this label on the inside of the glove box. It is very helpful if you ever need to order parts. On this label, you will ﬁnd the following: (cid:127) VIN (cid:127) Model designation (cid:127) Paint information (cid:127) 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 airbag system. Before attempting to add anything electrical to your vehicle, see Servicing Your Airbag-Equipped Vehicle on page 1-77.

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 and not snow, etc., be sure to get it ﬁxed.

5-127

Instrument Panel Fuse Block

The fuse block access door is on the driver’s side edge of the instrument panel. Pull off the cover to access the fuse block.

To remove fuses, hold the end of the fuse between your thumb and index ﬁnger and pull straight out. You may have spare fuses located behind the fuse block access door. These can be used to replace a bad fuse. However, make sure it is of the correct amperage.

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

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

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 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 may not be covered by warranty.

6-2

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.

Using Your Maintenance Schedule We at General Motors 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 GM Goodwrench® dealer.

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 4-50. are driven on reasonable road surfaces within legal driving limits. are driven off-road in the recommended manner. See Off-Road Driving on page 4-20. use the recommended fuel. See Gasoline Octane on page 5-6.

The services in Scheduled Maintenance on page 6-4
should be performed when indicated. See Additional Required Services on page 6-6 and Maintenance Footnotes on page 6-8 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 GM Goodwrench® dealer to have a qualiﬁed technician do the work.

Some maintenance services can be complex. So, unless you are technically qualiﬁed and have the necessary equipment, you should have your GM Goodwrench® dealer do these jobs. When you go to your GM Goodwrench® dealer for your service needs, you will know that GM-trained and supported service technicians will perform the work using genuine GM parts. If you want to purchase service information, see Service Publications Ordering Information on page 7-13. Owner Checks and Services on page 6-10 tells you what should be checked, when to check it and what you can easily do to help keep your vehicle in good condition.

(cid:127) (cid:127) (cid:127) (cid:127) See Engine Oil Life System (Gasoline Engine) on page 5-23 for information on the Engine Oil Life System and resetting the system. When the CHANGE ENGINE OIL 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 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.

The proper replacement parts, ﬂuids and lubricants to use are listed in Recommended Fluids and Lubricants on page 6-13 and Normal Maintenance Replacement Parts on page 6-16. 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 GM parts.

Scheduled Maintenance When the CHANGE ENGINE OIL 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 may not indicate that vehicle service 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. Your GM Goodwrench® dealer has GM-trained service technicians who will perform this work using genuine GM 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.

Maintenance Footnotes † The U.S. Environmental Protection Agency or the California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of the vehicle’s useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded.

# Lubricate the front suspension, ball joints, steering linkage, transmission shift linkage and parking brake cable guides. Ball joints should not be lubricated unless their temperature is 10°F (−12°C) or higher, or they could be damaged. Vehicles used under severe commercial operating conditions require lubrication on a regular basis every 3,000 miles (5 000 km). (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 drum brake linings for wear or cracks. Inspect other brake parts, including drums, wheel cylinders, calipers, parking brake, etc.

6-8

(b) Visually inspect front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect power steering lines and hoses for proper hook-up, binding, leaks, cracks, chaﬁng, etc. Visually check constant velocity joints, rubber boots and axle seals for leaks. (c) Visually inspect hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, ﬁttings and clamps; replace with genuine GM 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. (d) Visually inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. (e) Make sure the safety belt reminder light and all your 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, body door hinges, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, tailgate hinges, tailgate linkage, tailgate handle pivot points, latch bolt, fuel door hinge, locks and folding seat hardware. 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) Check vent hose at transfer case for kinks and proper installation. (h) Change automatic transmission ﬂuid and ﬁlter if the vehicle GVWR is over 8600 lbs or 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 perform this service. See Engine Coolant on page 5-35 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap and ﬁller neck. Pressure test the cooling system and pressure cap.

6-9

(j) 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. (k) Inspect system. Check all fuel and vapor lines and hoses for proper hook-up, routing and condition. Check that the purge valve works properly (if equipped). Replace as needed. (l) Change clutch ﬂuid (or every 24 months, whichever occurs ﬁrst). (m) Change automatic transmission ﬂuid and ﬁlter 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.

(n) Vehicles with diesel engine or with GVWR above 10,000 lbs (4 536 kg) only: Inspect shields for damage or looseness. Adjust or replace as required. This is a Noise Emission Control Service. Applicable only to vehicles sold in the United States. (p) If you drive regularly under dusty conditions, inspect the ﬁlter or change indicator (if equipped) 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 GM Goodwrench® dealer 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 6-13. At the First 100, 1,000 and 6,000 Miles (160, 1 600 and 10 000 km) Check dual wheel nut torque. For proper torque, see Capacities and Speciﬁcations on page 5-136.

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 (Gasoline Engine) on page 5-20 for further details.

6-10

It is important to check your oil regularly

Notice: and keep it at the proper level. Failure to keep your engine oil at the proper level can cause damage to your 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 5-35 for further details. Windshield Washer Fluid Level Check Check the windshield washer ﬂuid level in the windshield washer tank and add the proper ﬂuid if necessary.

At Least Once a Month Tire Inﬂation Check Visually inspect your tires and make sure tires are inﬂated to the correct pressures. Do not forget to check your spare tire. See Tires on page 5-76 for further details. Check to make sure the spare tire is stored securely. Push, pull and then try to turn the spare tire. If it moves, tighten it. See Changing a Flat Tire on page 5-96.

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 2-49 if necessary. 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 starter should work only in PARK (P) or NEUTRAL (N). If the starter works in any other position, contact your GM Goodwrench® dealer for service.

6-11

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 2-49 if necessary. Be ready to apply the regular brake immediately if the vehicle begins to move.

3. With the engine off, turn the ignition to RUN, 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 GM Goodwrench® dealer for service.

Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn the ignition to LOCK in each shift lever position.

The ignition should turn to LOCK only when the shift lever is in PARK (P). The key should come out only in LOCK.

Contact your GM Goodwrench® dealer 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.

6-12

(cid:127) (cid:127) Park on a fairly steep hill, with the vehicle facing downhill. Keeping your foot on the regular brake, set the parking brake.

To check the parking brake’s holding ability: With the engine running and 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. 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 GM Goodwrench® dealer 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.

Customer Assistance and Information

Customer Satisfaction Procedure Your satisfaction and goodwill are important to your dealer and to Chevrolet. Normally, any concerns with the sales transaction or the operation of your vehicle will be resolved by your dealer’s sales or service departments. Sometimes, however, despite the best intentions of all concerned, misunderstandings can occur. If your concern has not been resolved to your satisfaction, the following steps should be taken:

STEP ONE: Discuss your concern with a member of dealership management. Normally, concerns can be quickly resolved at that level. If the matter has already been reviewed with the sales, service or parts manager, contact the owner of the dealership or the general manager.

STEP TWO: If after contacting a member of dealership management, it appears your concern cannot be resolved by the dealership without further help, contact the Chevrolet Customer Assistance Center by calling 1-800-222-1020. In Canada, contact GM of Canada Customer Communication Centre by calling 1-800-263-3777 (English) or 1-800-263-7854 (French).

We encourage you to call the toll-free number in order to give your inquiry prompt attention. Please have the following information available to give the Customer Assistance Representative:
