† 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) Visually inspect brake lines and hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect drum brake linings for wear or cracks. Inspect disc brake pads for wear and rotors for surface condition. Inspect other brake parts, including drums, wheel cylinders, 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. 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 and fuel door hinges, latches and locks (including glove box and console doors), hood latch assembly, secondary latch, pivots, spring anchor, release pawl and any moving seat hardware. Lubricate hood safety lever pivot and prop rod pivot and tailgate latch bolt, handle assembly pivot points and 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 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. |
(i) Drain, flush and refill cooling system. See Engine Coolant for what to use. Inspect hoses. Clean radiator, condenser, pressure cap and filler neck. Pressure test the cooling system and pressure cap.
