EXPLANATION OF MAINTENANCE ITEMS ENGINE COOLANT Drain the cooling system and refill with an ethylene-glycol type coolant. Inspect hoses and connections for corrosion and leaks. Tighten connections and replace parts when necessary. A qualified technician should perform these operations. (For further details, refer to ЉRadiator, Condenser and HosesЉ in the ЉVehicle Maintenance and CareЉ section of the Owner's Manual). NOTE: Your Toyota is equipped with Genuine Toyota Super Long-Life Coolant. The replacement intervals for engine coolant recommended in this booklet are based on replacement with Genuine Toyota Super Long-Life Coolant or similar high-quality non-silicate, non-amine, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). If another type of ethylene-glycol coolant is used, replacement intervals may be different. ENGINE OIL AND FILTER Replace the oil filter and drain and refill the engine oil at specified intervals. For recommended oil grade and viscosity, refer to the Owner's Manual. When using E85 fuel, your engine oil may need to replaced more often. If using E85 fuel more than 50% of the time, change the engine oil every 2,500 miles or 3 months. If using E85 fuel less than 50% of the time, follow the normal engine oil change schedule (5,000 miles or 6 months). ENGINE VALVE CLEARANCE Check for tappet noise and engine vibration and adjust if necessary, 2UZ-FE engine only. 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 gas leakage. Tighten connections or replace parts as necessary. FRONT OR REAR DIFFERENTIAL OIL Inspect or replace at specified intervals. When performing inspections, check each component for signs of leakage. If you discover any leakage, have it repaired by a qualified technician immediately. 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 or replace parts as necessary. FUEL TANK CAP GASKET Visually inspect for cracks, deterioration and damage and replace if necessary.
