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.

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.

ng maintenance work on a vehicle can

Per 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- 10. “Part B: Owner Checks and Services” tells you what should be checked and when. It also explains what YOU can easiiy do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your dealer’s service department or another qualified service center should perform. “Part D: Recommended Fluids and Lubricants” lists some recommended products necessary to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” is a place for you to record and keep track of the maintenance performed on your vehicle. Keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

6-3

Part A: Scheduled Services

Maintenance

and chassis lubrication

This part contains engine oil scheduled maintenance which explains the engine oil life system and how it indicates when to change the engine oil and filter. Lubricate chassis components with each oil change. Also, listed are scheduled maintenance services which are to be performed at the mileage intervals specified.

Using Your Maintenance Schedule

We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or in many other ways. Because of all the different ways people use their vehicles, maintenance needs vary. You may need more frequent checks and replacements. So please read the following and note how you drive. If you have any questions on how to keep your vehicle in good condition, see your dealer.

6-4

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. This schedule is for vehicles that:

carry passengers and cargo within recommended limits. You will find these limits on your vehicle’s Certification/Tire label. See Loading Your Vehicle on page 4-56. are driven on reasonable road surfaces within legal driving limits. are driven off-road in the recommended manner. See Off-Road Driving with Your Four-Wheel-Drive Vehicle on page 4-2 I. use the recommended fuel. See Gasoline Octane on page 5-5.

Scheduled Maintenance

The services shown in this schedule up to 100,000 miles (1 66 000 km) should be repeated after 100,000 miles (166 899 km) at the same intervals for the life of this vehicle. The services shown at 150,000 miles (240 000 km) and 200,000 miles (332 000 km) should be repeated at the same interval after 150,000 miles (240 000 km) and 200,000 miles (332 000 km) for the life of this vehicle. See Part B: Owner Checks and Services on page 6- I I and Part C: Periodic Maintenance Inspections on page 6- 16. 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. + A good time to check your brakes is during tire rotation. See Brake System Inspection on page 6- 17.

Engine Oil and Chassis Lubrication Scheduled Maintenance Change engine oil and filter as indicated by the GM Oi! Life SystemTM (or every 12 months, whichever occurs first). Reset the system. Your vehicle has a computer system that lets you know when to change the engine 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 oil 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. A CHANGE ENGINE OIL 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.

6-5

If the system is ever reset accidentally, you must change your oil at 3,000 miles (5 000 km) since your last oil change. Remember to reset the oil life system whenever the oil is changed. See Engine Oil on page 5-17for information on resetting the system. An Emission Control Service. Lubricate chassis components with each engine oil and filter change. Vehicles used under severe commercial operating conditions require lubrication on a regular basis every 3,000 miles (5 000 km). 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. After the services are performed, record the date, odometer reading and who performed the service on the maintenance record pages in Part E of this schedule.

Part B: Owner Checks and Services

Listed in this part are owner checks and services which should be performed at the intervals specified to help ensure the safety, dependability and emission control performance of your vehicle. 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 Part D.

At the First 100, 1,000 and 6,000 Miles (160, 1 600 and 10 000km)

Check dual wheel nut torque. For proper torque, see Capacities and Specifications on page 5-120.

At Each Fuel Fill

It is imponlant for you or a service station attendant 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 5- I7 for further details.

Engine Coolant Level Check Check the engine coolant level and add DEX-COOL@ coolant mixture if necessary. See Engine Coolant on page 5-33 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. See Windshield Washer Fluid on page 5-46 for further details.

At Least Once a Month Tire Inflation Check

Make sure tries are inflated to the correct pressures. Don’t forget to check your spare tire. See Tires on page 5-72 for further details. Cassette Tape Player Service Clean cassette tape player. Cleaning should be done every 50 hours of tape play. See Audio System(s) on page 3-68 for further details.

6-1 1

At Least Twice a Year Restraint System Check 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 air bag coverings, and have them repaired or replaced. (The air bag system does not need regular maintenance.) Wiper Blade Check Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. Also see Cleaning the Outside of Your Vehicle on page 5-105. Spare Tire Check At least twice a year, after the monthly inflation check of the spare tire determines that the spare is inflated to the correct tire inflation pressure, make sure that the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrenchhatchet to tighten the cable. See Changing a Flat Tire on page 5-84. 6-1 2

Engine Air Cleaner Filter Restriction Indicator Check (If Equipped) Your vehicle has an indicator located on the air cleaner in the engine compartment that lets you know when the air cleaner filter is dirty and needs to be changed. Check indicator at least twice a year or when your engine oil is changed, whichever occurs first. See Engine Air Cleaner/Filter on page 5-23 for more information. Inspect your air cleaner filter restriction indicator more often if the vehicle is used in dusty areas or under off road conditions. Weatherstrip Lubrication 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 more frequent application may be required. See Part D: Recommended Fluids and Lubricants on page 6-18. Manual Transmission Check Check the transmission fluid level; add if needed. See Manual Transmission Fluid on page 5-31. Check for leaks. A fluid leak is the only reason for fluid loss. Have the system inspected and repaired if needed.

Automatic Transmission Check Check the transmission fluid level; add if needed. See Automatic Transmission Fluid (Except Allison Transmission) on page 5-25 or Automatic Transmission Fluid (Allison Transmission) on page 5-28. A fluid loss may indicate a problem. Check the system and repair if needed. Hydraulic Clutch System Check Check the fluid level in the clutch reservoir. See Hydraulic Clutch on page 5-32. A fluid loss in this system could indicate a problem. Have the system inspected and repaired at once. At Least Once a Year Key Lock Cylinders Service Lubricate the key lock cylinders with the lubricant specified in Part D. Body Lubrication Service Lubricate all body door hinges, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, tailgate hinge, tailgate linkage, tailgate handle pivot points, latch bolt, fuel door hinge, locks and folding seat hardware. Part D tells you what to use. More frequent lubrication may be required when exposed to a corrosive environment.

Starter Switc- I- Check

I When you are doing this check, the vehicle

could move suddenly. If it does, you or others could be injured. Follow the steps below.

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 2-44 if necessary. Do not use the accelerator pedal, and be ready to turn off the engine immediately if it starts.

3. On automatic transmission vehicles, 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, your vehicle needs service. On manual transmission vehicles, put the shift lever in NEUTRAL (N), push the clutch down halfway and try to start the engine. The starter should work only when the clutch is pushed down all the way to the floor. If the starter works when the clutch isn’t pushed all the way down, your vehicle needs service.

6-1 3

Automatic Transmission Shift Lock Control System Check

When you are doing this check, the vehicle could move suddenly. If it does, you or others could be injured. Follow the steps below.

Ignition Transmission Lock Check While parked, and with the parking brake set, try to turn the

ignition key to LOCK in each shift lever position. With an automatic transmission, the key should turn to LOCK only when the shift lever is in PARK (P). With a manual transmission, the key should turn to LOCK only when you press the key release button. all vehicles, the key should come out only in LOCK.

On

Before you start, be sure you have enough room around the vehicle. It should be parked on a level surface. Firmly apply the parking brake. See Parking Brake on page 2-44 if necessary. Be ready to apply the regular brake immediately if the vehicle begins to move. With the engine off, turn the key to the RUN position, but don’t 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), your vehicle needs service.

6-1 5

Part C: Periodic Maintenance Inspections Listed in this part are inspections and services which should be performed at least twice a year (for instance, each spring and fall). You should let your dealer’s service department or other qualified service center do these jobs. Make sure any necessary repairs are completed at once. Proper procedures to perform these services may be found in a service manual. See Service Publications Ordering Information on page 7- IO. Steering and Suspension Inspection Inspect the front and rear suspension and steering system for damaged, loose or missing parts, signs of wear or lack of lubrication. Inspect the power steering lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc.

Exhaust System Inspection Inspect the complete exhaust system. Inspect the body near the exhaust system. Look for broken, damaged, missing or out-of-position parts as well as open seams, holes, loose connections or other conditions which could cause a heat build-up in the floor pan or could let exhaust fumes into the vehicle. See Engine Exhaust on page 2-49. Fuel System Inspection Inspect the complete fuel system for damage or leaks. Engine Cooling System Inspection Inspect the hoses and have them replaced if they are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps; replace as needed. Clean the outside of the radiator and air conditioning condenser. To help ensure proper operation, a pressure test of the cooling system and pressure cap is recommended at least once a year.

6-1 6

Brake System Inspection Inspect the complete system. 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. You may need to have your brakes inspected more often if your driving habits or conditions result in frequent braking.

Throttle System Inspection Inspect the throttle 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 and cruise control cables. Transfer Case and Front Axle (Four-Wheel Drive) Inspection Every 12 months or at engine oil change intervals, check front axle and transfer case and add lubricant when necessary. A fluid loss could indicate a problem; check and have it repaired, if needed. On manual shift transfer case, oil the control lever pivot point. Check vent hose at transfer case for kinks and proper installation. More frequent lubrication may be required on off-road use.

Customer Assistance 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 in Oshawa by calling 1-800-263-3777 (English) or 1-800-263-7854 (French).

7-2

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:

Vehicle Identification Number (This is available from the vehicle registration or title, or the plate at the top left of the instrument panel and visible through the windshield.) Dealership name and location Vehicle delivery date and present mileage

When contacting Chevrolet, please remember that your concern will likely be resolved at a dealer’s facility. That is why we suggest you follow Step One first if you have a concern.

STEP THREE: Both General Motors and your dealer are committed to making sure you are completely satisfied with your new vehicle. However, if you continue to remain unsatisfied after following the procedure outlined in Steps One and Two, you should file with the GM/BBB Auto Line Program to enforce any additional rights you may have. Canadian owners refer to your Warranty and Owner Assistance Information booklet for information on the Canadian Motor Vehicle Arbitration Plan (CAMVAP).

The BBB Auto Line Program is an out of court program administered by the Council of Better Business Bureaus to settle automotive disputes regarding vehicle repairs or the interpretation of the New Vehicle Limited Warranty. Although you may be required to resort to this informal dispute resolution program prior to filing a court action, use of the program is free of charge and your case will generally be heard within 40 days. If you do not agree with the decision given in your case, you may reject it and proceed with any other venue for relief available to you. You may contact the BBB using the toll-free telephone number or write them at the following address: BBB Auto Line Council of Better Business Bureaus, Inc. 4200 Wilson Boulevard Suite 800 Arlington, VA 22203-1 804 Telephone: 1-800-955-51 00 This program is available in all 50 states and the District of Columbia. Eligibility is limited by vehicle age, mileage and other factors. General Motors reserves the right to change eligibility limitations and/or discontinue its participation in this program.

Courtesy Transportation Chevrolet has always exemplified quality and value in its offering of motor vehicles. To enhance your ownership experience, we and our participating dealers are proud to offer Courtesy Transportation, a customer support program for new vehicles. The Courtesy Transportation program is offered to retail purchase/lease customers in conjunction with the Bumper-to-Bumper coverage provided by the New Vehicle Limited Warranty. Several transportation options are available when warranty repairs are required. This will reduce your inconvenience during warranty repairs. Plan Ahead When Possible When your vehicle requires warranty service, you should contact your dealer and request an appointment. By scheduling a service appointment and advising your service consultant of your transportation needs, your dealer can help minimize your inconvenience. If your vehicle cannot be scheduled into the service department immediately, keep driving it until it can be scheduled for service, unless, of course, the problem is safety-related. If it is, please call your dealership, let them know this, and ask for instructions. If the dealer requests that you simply drop the vehicle off for service, you are urged to do so as early in the work day as possible to allow for same day repair.

7-7

Courtesy Rental Vehicle When your vehicle is unavailable due to overnight warranty repairs, your dealer may arrange to provide you with a courtesy rental vehicle or reimburse you for a rental vehicle you obtained, at actual cost, up to a maximum of $30.00 per day supported by receipts. This requires that you sign and complete a rental agreement and meet state, local and rental vehicle provider requirements. Requirements vary and may include minimum age requirements, insurance coverage, credit card, etc. You are responsible for fuel usage charges and may also be responsible for taxes, levies, usage fees, excessive mileage or rental usage beyond the completion of the repair. Generally it is not possible to provide a like-vehicle as a courtesy rental.

Transportation Options

Warranty service can generally be completed while you wait. However, if you are unable to wait Chevrolet helps minimize your inconvenience by providing several transportation options. Depending on the circumstances, your dealer can offer you one of the following: Shuttle Service Participating dealers can provide you with shuttle service to get you to your destination with minimal interruption of your daily schedule. This includes a one way shuttle ride to a destination up to 10 miles from the dealership. Public Transportation or Fuel Reimbursement If your vehicle requires overnight warranty repairs, reimbursement up to $30 per day (five day maximum) may be available for the use of public transportation such as taxi or bus. In addition, should you arrange transportation through a friend or relative, reimbursement for reasonable fuel expenses up to $1 0 per day (five day maximum) may be available. Claim amounts should reflect actual costs and be supported by original receipts.

7-8

Additional Program Information

Courtesy Transportation is available during the Bumper-to-Bumper warranty coverage period, but it is not part of the New Vehicle Limited Warranty. A separate booklet entitled “Warranty and Owner Assistance Information” furnished with each new vehicle provides detailed warranty coverage information. Courtesy Transportation is available only at participating dealers and all program options, such as shuttle service, may not be available at every dealer. Please contact you dealer for specific information about availability. All Courtesy Transportation arrangements will be administered by appropriate dealer personnel. Canadian Vehicles: For warranty repairs during the Complete Vehicle Coverage period of the General Motors of Canada New Vehicle Limited Warranty, alternative transportation may be available under the Courtesy Transportation Program. Please consult your dealer for details. General Motors reserves the right to unilaterally modify, change or discontinue Courtesy Transportation at any time and to resolve all questions of claim eligibility pursuant to the terms and conditions described herein at its sole discretion.

Reporting Safety Defects to the United States Government If you believe that your vehicle has a defect which could cause a crash or could cause injury or death, you should immediately inform the National Highway Traffic Safety Administration (NHTSA), in addition to notifying General Motors. If NHTSA receives similar complaints, it may open an investigation, and if it finds that a safety defect exists in a group of vehicles, it may order a recall and remedy campaign. However, NHTSA cannot become involved in individual problems between you, your dealer or General Motors. To contact NHTSA, you may either call the Auto Safety Hotline toll-free at 1-800-424-9393 (or 366-0123 in the Washington, D.C. area) or write to: NHTSA, U.S. Department of Transportation Washington, D.C. 20590 You can also obtain other information about motor vehicle safety from the hotline.

Supplement to the 2003 Silverado, Sierra, Tahoe, Suburban,

r’s Manual

Passenger Sensing System Accident statistics show that children are safer if they are restrained in the rear rather than the front seat. General Motors, therefore, recommends that child restraints be secured in a rear seat, including an infant riding in a rear-facing infant seat, a child riding in a forward-facing child seat and an older child riding in a booster seat. Never put a child in rear-facing child restraint in the tight front passenger seat unless your vehicle has the passenger sensing system and the passenger air bag status indicator shows off. Never put a rear-facing child restraint in the right front passenger seat unless the air bag is off.

A child in a rear-facing child restraint can be seriously injured or killed if the right front passenger’s air bag inflates. This is because the back of the rear-facing child restraint would be very close to the inflating air bag. Be sure the air bag is off before using a rear-facing child restraint in the right front seat position.

CAUTION:

(Continued)

Litho in U.S.A. Part No. 15189747

‘Copyright General Motors Corporation 06/24/02 All Rights Reserved

The passenger sensing system is designed to turn off the right front passenger’s frontal air bag if:

the right front passenger seat is unoccupied the system determines that an infant is present in a rear-facing infant seat the system determines that a small child is present in a forward-facing child restraint the system determines that a small child is present in a booster seat a right front passenger takes hislher weight off of the seat for a period of time the right front passenger seat is occupied by a smaller person, such as a child who has outgrown child restraints or if there is a critical problem with the air bag system or the passenger sensing system.

For some children who have outgrown child restraints and for very small adults, the passenger sensing system may or may not turn off the right front passenger’s frontal air bag, depending upon the person’s seating posture and body build. Everyone in your vehicle who has outgrown child restraints should wear a safety belt properly - whether or not there is an air bag for that person.

Even though the passenger sensing system is designed to turn off the passenger’s frontal air bag if the system detects a rear-facing child restraint, no system is fail-safe, and no one can guarantee that an air bag will not deploy under some unusual circumstance, even though it is turned off. General Motors, therefore, recommends that rear-facing child restraints be secured in the rear seat whenever possible, even if the air bag is off.
