EXPLANATION OF MAINTENANCE ITEMS Driver's Floor Mat • Only use the driver's floor mat designed specifically for the model and model year of your vehicle. • 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/Inverter Coolant When inspecting, visually check the engine/inverter coolant level on the see-through 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 highquality non-silicate, non-amine, nonnitrate, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). A qualified technician should perform these operations. Please refer to the important safety precautions found on the inside front cover of this booklet. Check the radiator and condenser for blockage by leaves, dirt or insects and clean if necessary. Also check the hose connections for corrosion and condition of installation. Note: Initial replacement is at 120 months/100,000 miles. Replace every 60 months/50,000 miles thereafter. 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 your Owner's Manual. The LS 600h L is equipped with a replaceable oil-filter element and oil-filter cap O-ring; replace both at each oil change. For instructions on how to reset the reminder light, refer to your Owner's Manual.
