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.) Engine Air Cleaner Filter Restriction Indicator Check 6.0 L Engine Only: Your vehicle has an engine air cleaner filter restriction indicator located on the air cleaner in the engine compartment. The indicator lets you know when the air cleaner filter is dirty and needs to be changed. Check the indicator at least twice a year or when your engine oil is changed, whichever occurs first. See Engine Air Cleaner/Filter on page 5-19 for more information. Inspect your air cleaner filter restriction indicator more often if the vehicle is used in dusty areas or under off road conditions. 5.3 L Engine: See Scheduled Maintenance on page 6-5. Wiper Blade Check Inspect wiper blades for wear or cracking. Replace blade inserts that appear worn ordamaged or that streak or miss areas of the windshield. Also see Cleaning the Outside of Your Vehicle on page 5-93. 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. Spare Tire Check At least twice a year, after the monthly inflation check of the spare tire determines that the spare is inflated to the correct tire inflation pressure, make sure that the spare tire is stored securely. Push, pull, and then try to rotate or turn the tire. If it moves, use the wheel wrenchhatchet to tighten the cable. See Changing a Flat Tire on page 5-74. Automatic Transmission Check Check the transmission fluid level; add if needed. See Automatic Transmission Fluid on page 5-21. A fluid loss may indicate a problem. Check the system and repair if needed. 6-1 1
