Footnotes

(1): 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 the recall liability prior to the completion of the vehicle's useful life. It is, however, strongly recommended that all recommended maintenance services be performed at the indicated intervals and that the maintenance be recorded.

(2):  Lubricate the suspension, steering linkage, transaxle shift linkage and the underbody contact points and linkage.

(3): Visually inspect the brake lines and the hoses for proper hook-up, binding, leaks, cracks, chafing, etc. Inspect the disc brake pads for wear and inspect the rotors for surface condition. Inspect other brake parts, including the calipers, the parking brake, etc. Inspect the parking brake adjustment.

(4): Visually inspect the front and rear suspension and the steering system for damaged, loose or missing parts, for signs of wear, or for lack of lubrication. Inspect the power steering lines and the hoses for proper hook-up, binding, leaks, cracks, chafing, etc.

(5): Visually inspect the hoses and replace any that are cracked, swollen or deteriorated. Inspect all pipes, fittings and clamps. Replace as needed. To help ensure proper operation, pressure test the cooling system and the pressure cap, and clean the outside of the radiator and the air conditioning condenser at least once a year.

(6): Visually inspect the wiper blades for wear or cracking. Replace all blade inserts that appear worn or damaged or that streak or miss areas of the windshield.

(7): Verify that the safety belt reminder light and all of the belts, buckles, latch plates, retractors and anchorages are working properly. If the vehicle has a built-in child restraint, verify that the harness straps, latch plates, buckle, clip, child head restraint and anchorages are working properly. Look for any other loose or damaged safety belt system parts. Repair anything that might keep a safety belt system from doing the job. Replace any torn or frayed safety belts. Also look for any opened or broken air bag coverings, and repair or replace these parts. The air bag system does NOT need regular maintenance.

(8): Lubricate all key lock cylinders, hood latch assembly, secondary latch, pivots, spring anchor, release pawl, rear compartment hinges, outer liftgate handle pivot points, rear door detent link, roller mechanism, liftgate handle pivot points, latch bolt, fuel door hinge, cargo door hinge, locks and folding seat hardware. Lubricate the hood and door hinges, rear folding seats, liftgate hinges, fuel door hinge, power sliding door cable and sliding door tracks. More frequent lubrication may be required when the vehicle has been exposed to a corrosive environment. Applying silicone grease on weather-strips with a clean cloth will ensure longer life, create a better seal, and prevent sticking or squeaking.

(9): If the vehicle is driven regularly under dusty conditions, the filter may require replacement more often.

(10): Change the automatic transmission transaxle fluid and the filter if the vehicle is mainly driven under one or more of the following conditions:

    • In heavy city traffic where the outside temperature regularly reaches 32°C (90°F) or higher
    • In hilly or mountainous terrain
    • When doing frequent trailer towing
    • In uses such as found in taxi, police or delivery service
(11): Drain, flush and refill the cooling system. Refer to Cooling System Draining and Filling for the proper procedure. Inspect the hoses. Clean the radiator, the condenser, the pressure cap, and the filler neck. Pressure test the cooing system and the pressure cap.

(12): Inspect the throttle system for interference or binding and for damaged or missing parts. Replace parts as needed. Replace any components that have high effort or excessive wear. Do NOT lubricate the accelerator or the cruise control cables.

(13): A fluid loss in any vehicle system could indicate a problem. Inspect and repair the system and inspect the fluid level. Add fluid if needed.
