Explanation of Maintenance Items Differential Oil Replace at specified intervals. When performing inspections, check each component for signs of leakage. If you discover any leakage, have it repaired by a qualified technician immediately. Drive Belts Inspect for cracks, excessive wear and oiliness. Check the belt tension and adjust if necessary. Replace the belts if they are damaged. Drive Shaft Boots Check the drive shaft boots and clamps for cracks, deterioration and damage. Replace any deteriorated or damaged parts and, if necessary, repack the grease. Selected models also require periodic inspection of the drive shaft bolt for proper torque. A qualified technician should perform these operations. Engine Air Filter Replace at specified intervals. When performing inspections, check for damage, excessive wear and oiliness, and replace if necessary. Engine Coolant Drain and flush the cooling system and refill with an ethylene-glycol type coolant. Inspect the radiator, condenser and/or intercooler for leaves, dirt and insects and clean if necessary. Inspect hoses and connections for corrosion and leaks. Tighten connections and replace parts as necessary. A qualified technician should perform these operations. (For further details, refer to "Radiator, Condenser and Hoses" in the "Vehicle Maintenance and Care" section of the Owner's Manual.) Note: Your Toyota is equipped with Genuine Toyota Super Long-Life Coolant. The replacement intervals for engine coolant recommended in this booklet are based on replacement with Genuine Toyota Super Long-Life Coolant or similar highquality non-silicate, non-amine, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). If another type of ethylene-glycol coolant is used, replacement intervals may be different. Engine Oil and Oil Filter Replace the oil filter and drain and refill the engine oil at specified intervals. For recommended oil grade and viscosity, refer to the Owner's Manual. 37
