Door handles, hinges, and locks should be lubricated at least once a year. Use light lithium-base grease for hinges and handles. Use spray graphite for door locks. Do NOT inject oil into door locks; it attracts and holds dirt and grit, causing binding and stiff operation, particularly in cold weather.
Additionally, a small amount of grease should be applied to the hood and trunk latches and hinges periodically. Other moving components such as seat back pivots or cargo compartments should be attended to on as-needed basis.
When performing lubrication of any item in the passenger area (doors, locks, etc.) apply lubricant sparingly and thoroughly wipe up the excess to prevent lubricant getting onto upholstery and/or clothing.
Keep the exterior of the vehicle clean. Dirt can cause small scratches in the paint and the chemicals in road dirt and air pollution can cause paint damage. Frequent washing is recommended; this is particularly important for vehicles used in snowy areas, near salt water or any vehicle used off the road.
Wash the vehicle in the shade when the body is not hot to the touch. Wash with mild car-wash soap and rinse thoroughly before the soap dries on the paint. It may be necessary to wash and rinse the vehicle in sections to prevent the soap from streaking the paint. NEVER use gasoline or strong solvents to clean painted surfaces.
Use a chamois or soft, lint-free rag to dry the exterior. Wring the drying rag out frequently and keep it away from areas in which it may pick up dirt or grit. If the rag or chamois is dropped on the ground, rinse it thoroughly before continuing; it may carry grit that will scratch the finish.
After the paint is completely dry, the bodywork may be waxed with any of the commercial car polishes or waxes. Read the can carefully before purchase; use good judgment in deciding the condition of the finish. A wax for older finishes will have more abrasive to remove oxidized paint. A 'new car' wax will have much less abrasive. Toyota has some suggestions on washing and waxing your Toyota truck in the owner's guide.
