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, 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 damage, excessive wear and oiliness. Replace if necessary. Engine Coolant (RX 350) or Engine/Inverter Coolant (RX 450h) When inspecting, visually check the level of the engine coolant or engine/inverter coolant on the seethrough reservoir. Add coolant as necessary. When replacing, drain and flush the cooling system and refill with coolant. Always use Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, nonamine, 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. RX 450h owners: Please refer to the important safety precautions 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 of engine coolant is at 120 months/100,000 miles. Replace every 60 months/ 50,000 miles thereafter. Initial replacement of inverter coolant is at 180 months/150,000 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. SAE 0W-20 oil is the best choice for good fuel economy and good starting in cold weather. If SAE 0W-20 is not available, SAE 5W-20 may be used; however, it must be replaced with SAE 0W-20 at the next oil change. See your Lexus dealer for 28 Scheduled Maintenance Log
