Rack and Pinion AssemblyInspect the rack and pinion assembly for signs of leak-
age, damage and loose electrical connections. Tighten
connections and if you discover any leakage or dam-
age, have it repaired immediately by a qualified tech-
nician.Road TestWhile driving the vehicle, check for proper operation
of engine, transmission, brakes and steering. Also
check for abnormal noise or vibration from any part
of the vehicle.Spark PlugsInstall new plugs of the same type as originally
equipped. Refer to your Owner’s Manual. A qualified
technician should perform this operation.Steering Linkage and BootsWith the vehicle stopped, check for excessive freeplay
in the steering wheel. Inspect the linkage for bending
and damage and the dust boots for deterioration, cracks and damage. Replace any damaged parts. A
qualified technician should perform these operations.
Timing Belt (except GS 300 and IS)Replace every 90,000 miles or 108 months. A qualified
technician should perform this operation. (The GS 300
and IS are equipped with a timing chain, which
requires no periodic inspection.)Tire RotationTires should be rotated according to the instructions
in your Owner’s Manual. When rotating tires, check
pressure and check for damage and uneven wear. If
the spare is not rotated, check the condition and pres-
sure of the spare.Transfer Case Fluid (GS 300 All-Wheel Drive,
IS 250 All-Wheel Drive)Periodic fluid checks and replacement of the transfer
case fluid are not required. Any repairs that require
adding or replacing fluid should be performed by a
qualified technician following procedures in Lexus
service and repair publications.MAINTENANCE
