EXPLANATION OF MAINTENANCE ITEMS 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 ethyleneglycol 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. 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. 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 oil specifically formulated for your vehicle's engine. For instructions on how to reset the reminder light, refer to your Owner's Manual. Note: If you do the majority of your driving under any of the special operating conditions indicated on page 44, you should replace the engine oil and oil filter every six months or 5,000 miles, regardless of the oil used or the certification of the vehicle. Exhaust Pipes and Mountings Visually inspect the exhaust pipes, muffler and hangers for cracks, deterioration and damage. Start the engine and listen carefully for any exhaust leakage. Tighten connections and replace parts as necessary. MAINTENANCE 70 Note: Initial replacement is at 120 months/100,000 miles. Replace every 60 months/50,000 miles thereafter. Scheduled Maintenance Log
