2010 Lexus IS 350 Scheduled Maintenance Guide - Page 29

EXPLANATION OF MAINTENANCE ITEMS Brake Pads, Calipers and Rotors Check brake pads and rotors for excessive wear; check brake rotors for runout. Check brake calipers for fluid leakage. Check the parking brake linings (shoes) and drums for scoring, burning, fluid leakage, broken parts and excessive wear. Some models are equipped with directional rotors. When servicing these rotors, reinstall at same location. A qualified technician should perform these operations. See inside front cover for additional brake information. Differential Oil Inspect each differential component for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician. Refer to your Owner's Manual for fluid specifications. For ISF, replace rear differential oil at specified intervals. Drive Belt Inspect for cracks, excessive wear and oiliness. Check the belt tension and adjust if necessary. Replace the belt if it is damaged. Engine Air Filter Check for damage, excessive wear 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 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-nitrate, non-borate ethylene-glycol coolant with long-life hybrid organic acid technology (i.e., a combination of low phosphates and organic acids). Check that the radiator is not blocked with leaves, dirt or insects and clean if necessary. Also check the hose connections for corrosion and condition of installation. 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.
