Scheduled Maintenance Services

Section

KEEP ENGINE OIL AT THE PROPER

LEVEL AND CHANGE AS RECOMMENDED

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

I protection Plan

Introduction Your Vehicle and the Environment Proper vehicle maintenance not only helps to keep your vehicle in good working condition, but also helps the environment. All recommended maintenance procedures are important. Improper vehicle maintenance or the removal of important components can significantly affect the quality of the air we breathe. Improper fluid levels or even the wrong tire inflation can increase the level of emissions from your vehicle. To help protect our environment, and to help keep your vehicle in good condition, please maintain your vehicle properly.

7-1

How This Section is Organized The remainder of this section is divided into five parts: “Part A: Scheduled Maintenance Services” shows what to have done and how often. Some of these services can be complex, so unless you are technically qualified and have the necessary equipment, you should let your dealer’s service department or another qualified service center do these jobs.

If you are skilled enough to do some work on your vehicle, you will probably want to get the service information GM publishes. See “Service Publications” in the Index. “Part B: Owner Checks and Services” tells you what should be checked whenever you stop for fuel. It also explains what you can easily do to help keep your vehicle in good condition. “Part C: Periodic Maintenance Inspections” explains important inspections that your GM dealer’s service department or another qualified service center should perform. “Part D: Recommended Fluids and Lubricants” lists some products GM recommends to help keep your vehicle properly maintained. These products, or their equivalents, should be used whether you do the work yourself or have it done. “Part E: Maintenance Record” provides a place for you to record the maintenance performed on your vehicle. Whenever any maintenance is performed, be sure to write it down in this part. This will help you determine when your next maintenance should be done. In addition, it is a good idea to keep your maintenance receipts. They may be needed to qualify your vehicle for warranty repairs.

7-2

Part A: Scheduled Maintenance Services Using Your Maintenance Schedule We at General Motors want to help you keep your vehicle in good working condition. But we don’t know exactly how you’ll drive it. You may drive very short distances only a few times a week. Or you may drive long distances all the time in very hot, dusty weather. You may use your vehicle in making deliveries. Or you may drive it to work, to do errands or i n many other ways. Because of all the different ways people use their GM vehicles, maintenance needs varv. You may even need more frequent checks and replacements than you‘ll find in the schedules in this section. So please read this section and note how you drive. If you have any questions on how to keep your vehicle in good condition. see your GM dealer. This part tells you the maintenance services you should have done and when you should schedule them. If you go to your dealer for your service needs, you’ll know that GM-trained and supported service people will perform the work using genuine GM parts. The proper fluids and lubricants to use are listed in Part D. Make sure whoever services your vehicle uses these. All parts should be replaced and all necessary repairs done before you or anyone else drives the vehicle. These schedules are for vehicles that:

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

Selecting the Right Schedule The proper maintenance schedule for your vehicle depends on which engine you have in your vehicle and how you use your vehicle. Gasoline engine vehicles and diesel engine vehicles have different maintenance requirements. If you have a diesel engine, follow a schedule designated for diesel engine vehicles only. If you have a gasoline engine. you must first determine whether your engine has a light duty or a heavy duty emissions classification. Follow a maintenance schedule designated for c easoline engines with the emissions classification (light duty or heavy duty) for your engine. See “Engine Identification” in the Index to find your engine‘s emission classification.

7-3

If your engine has more than one emissions classification, the classification is determined by the Gross Vehicle Weight Rating (GVWR) of your vehicle as shown on the Certification Label. See “Loading Your Vehicle” in the Index. Once you’ve determined your engine type and, if necessary, emissions classification, you’ll need to decide which of the two schedules is right for your vehicle. See Definitions for Maintenance Schedule I and Maintenance Schedule I1 following.

Schedule I Definition - Gasoline Engines With Light Duty Emissions

Follow Maintenance Schedule I if any one of these is true for your vehicle: iII Most trips are less than 5 to 10 miles (8 to 16 km). This is particularly

Footnotes 3 The California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. :$* Drive axle service:

Locking Differential - Drain fluid and refill at first engine oil change. At subsequent oil changes, check fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km).

0 Standard Differential - Check fluid level and add fluid as needed at

every oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km). More frequent lubrication may be required for heavy-duty or off-road use. 3500 HD Models with applications requiring extreme overload/trailer towing conditions and high speed (above 45 mph or 72 kmh) conditions for extended periods of time must have the drive axle fluid changed every 3,000 miles (5 000 km) or 3 months, whichever occurs first, or must use 75W-140 synthetic fluid meeting GM specifications.
