Cadillac 2007 owner manual 528

(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, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, rear compartment hinges, outer tailgate handle pivot points, latch bolt, fuel door hinge, 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)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.

(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. This service can be complex; you should have your dealer perform this service. See Engine Coolant on page 419 for what to use. Inspect hoses. Clean radiator, condenser, pressure cap, and filler neck. Pressure test the cooling system and pressure cap.

(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.
