Note:Initial replacement is at 120 months/100,000
miles. Replace every 60 months/50,000 miles there-
after.Engine Oil and Oil FilterReplace 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.
Refer to your Owner’s Manual.Engine Valve Clearance (except GS 300 and IS)Inspect for excessive lifter noise and engine vibration
and adjust if necessary. A qualified technician should
perform this operation. (The GS 300 and IS are
equipped with hydraulic valve lash adjusters, which
require no periodic clearance inspection or adjustment.)
Exhaust Pipes and MountingsVisually inspect the exhaust pipes, muffler and hang-
ers for cracks, deterioration and damage. Start the
engine and listen carefully for any exhaust gas leakage.
Tighten connections or replace parts as necessary.Fuel Lines and Connections, Fuel Tank Band and
Fuel Tank Vapor Vent System HosesVisually inspect for corrosion, damage, cracks and
loose or leaking connections. Tighten connections or
replace parts as necessary.Fuel Tank Cap GasketVisually inspect for cracks, deterioration and damage
and replace if necessary.Nuts and Bolts on ChassisRe-tighten the seat mounting bolts and front/rear
suspension member retaining bolts to specified torque. MAINTENANCE
