EXPLANATION OF MAINTENANCE ITEMS Brake Pads, Calipers and Rotors Check brake pads and rotors for excessive wear; check brake rotors for runout. Check brake calipers for fluid leakage. Some models are equipped with directional rotors. When servicing these rotors, reinstall at same location. A qualified technician should perform these operations. See inside front cover for additional brake information. Differential Oil Inspect each differential component for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician. Refer to your Owner's Manual for fluid specifications. For ISF, replace rear differential oil at specified intervals. Drive Belt Inspect for cracks, excessive wear and oiliness. Check the belt tension and adjust if necessary. Replace the belt if it is damaged. Driver's Floor Mat • Only use the driver's floor mat designed specifically for the model and model year of your vehicle, such as Lexus Genuine floor mats. • Always properly secure the driver's floor mat using the retaining hooks. • Never install another floor mat on top of the existing driver's floor mat. • Never install the driver's floor mat upside down. Engine Air Filter Check for excessive dirt, damage and oiliness. Replace if necessary. Engine Coolant When inspecting, visually check the engine coolant level on the seethrough reservoir. Add coolant as necessary. When replacing, drain the cooling system and refill with coolant. Always use Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, non-amine, non-nitrate, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). Check that the radiator is not blocked with leaves, dirt or insects and clean if necessary. Also check the hose connections for corrosion and condition of installation. A qualified technician should perform these operations. MAINTENANCE 69 Scheduled Maintenance Log
