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. 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.

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. Note: Initial replacement is at 120 months/100,000 miles. Replace every 60 months/50,000 miles thereafter.
