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.) 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 and fuel door hinges, rear compartment hinges, latches and locks including the glove box, console doors and the body hood and any moving seat hardware.
