EXPLANATION OF MAINTENANCE ITEMS Engine Coolant When inspecting, visually check the engine coolant level 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. 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. Some models are 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. Engine Valve Clearance (GX) Inspect for excessive lifter noise and engine vibration and adjust if necessary. A qualified technician should perform this operation. (The LX 570 and RX 350 are equipped with hydraulic valve lash adjusters that require no periodic clearance inspection or adjustment.) 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. Fuel Lines and Connections, Fuel Tank Band and Fuel Tank Vapor Vent System Hoses Visually inspect for corrosion, damage, cracks, and loose or leaking connections. Tighten connections and replace parts as necessary. Fuel Tank Cap Gasket Visually inspect for cracks, deterioration and damage and replace if necessary. MAINTENANCE 68 Scheduled Maintenance Log
