Part B: Owner Checks and Services Listed below 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, I 600 and IO 000 km) For vehicles with dual wheels, check dual wheel nut torque. For proper torque, see “Wheel Nut Torque’’ in the Index.

At Each Fuel Fill

Engine Oil Level Check the engine oil level and add the proper oil if necessary. See “Engine Oil” in the Index for further details.

Engine Coolant Level Check the engine coolant level and add the proper coolant mix if necessary. See ”Coolant” in the Index for further details.

Windshield Washer Fluid Level Check the windshield washer fluid level in the windshield washer tank and add the proper fluid if necessary. See ”Windshield Washer Fluid” in the Index for further details. At Least Once a Month

Tire Inflation Check tire inflation. Make sure tires are inflated to the pressures specified on the Certification/Tire label which is located on the rear edge of the driver’s door or on the incomplete vehicle document in the cab. See “Tires” in the Index for further details.

Cassette Deck Clean cassette deck. Cleaning should be done every 50 hours of tape play. See “Audio Systems” in the Index for further details. At Least Once a Year

Key Lock Cylinders Lubricate the key lock cylinders with the lubricant specified in Part D.

Body Lubrication Lubricate all fuel doors, body hood and body door hinges, tailgate and tailgate handle pivot points, latches, 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 Switch A CAUTION:

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. It

should be parked on a level surface.

2. Firmly apply both the parking brake (see “Parking Brake” in the Index

if necessary) and the regular brake. NOTE: 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.

Parking Brake and Automatic Transmission PARK (P) Mechanism Check

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: 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: Shift to PARK (P). Then release all brakes.

Lap and Shoulder Belts Condition and Operation Inspect belt system, including: webbing, buckles, latch plates, retractors, guide loops and anchors. Have a belt assembly replaced if the webbing has been cut or otherwise damaged.

Part C: Periodic Maintenance lnspections Listed below are inspections and services which should be performed at least twice a year (for instance, each spring and fall). You should let your GM dealer’s service department or other qualified service center do these jobs. Make sure any necessary repairs are completed at once.

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 power steering lines and hoses for proper hookup, binding, leaks, cracks, chafing, etc. (On vehicles equipped with manual steering gear, check for seal leakage.)

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” in the Index.

Accelerator Control System On gasoline engines. lubricate the pivot at the TBI throttle lever stud with engine oil. Do not oil any accelerator or cruise control cables. Replace any cables that have high effort or excessive wear.

Drive Axle Service Check readfront axle fluid level and add as needed. Check constant velocity Joints and axle seals for leaking.

Transfer Case (Four- Wheel Drive) Inspection Every 12 months or at oil change intervals, check front axle and transfer case and add lubricant when necessary. Oil the control lever pivot point and all exposed control linkage. Check vent hose at transfer case for kinks and proper installation. More frequent lubrication may be required on off-road use.
