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.) Automatic Transaxle Check Check the transaxle fluid level; add if needed. See Automatic Transaxle Fluid on page 5-24. A fluid loss may indicate a problem. Check the system and repair if needed. At Least Once a Year Key Lock Cylinders Service Lubricate the key lock cylinders with the lubricant specified in Part D. Wiper Blade Check Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn or damaged or that streak or miss areas of the windshield. Also see "Windshield Wiper and Wiper Blades" under Cleaning the Outside of Your Vehicle on page 5-93. Body Lubrication Service Lubricate all hood hinges, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, door hinges, rear compartment, glove box door, console door and any folding seat hardware. Part D tells you what to use. More frequent lubrication may be required when exposed to a corrosive environment. Weatherstrip Lubrication Silicone grease on weatherstrips will make them last longer, seal better, and not stick or squeak. Apply silicone grease with a clean cloth. During very cold, damp weather more frequent application may be required. See Part D: Recommended Fluids and Lubricants on page 6-16. 6-11
