EXPLANATION OF MAINTENANCE ITEMS Spark Plugs Replace at specified interval. A qualified technician should perform this operation. To ensure optimum engine performance on ES 350, replace only with Denso FK20HR11 plugs or equivalent. Steering Linkage and Boots With 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 (SC) Replace every 90,000 miles or 108 months. A qualified technician should perform this operation. Timing Chain (ES, GS, IS, LS) The ES, GS, IS and LS are equipped with a timing chain that requires no periodic inspection. Tire Rotation Tires 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 pressure of the spare. Tire-Pressure Warning Sensors A tire-pressure sensor is mounted on each full-size wheel. These sensors do not require periodic maintenance. When a sensor's long-life lithium battery becomes discharged, the battery should be replaced by a qualified technician following procedures in Lexus service and repair publications. Transfer Case/Transmission Inspect each transfer case/transmission component for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician. Note: The transfer case/transmission and transmission fluid are a completely sealed unit. Therefore, periodic checks and replacement of the transmission fluid are not required, and there is no dipstick on the transmission. Any repairs that require adding or replacing fluid should be performed by a qualified technician following procedures in Lexus service and repair publications. MAINTENANCE 69 Scheduled Maintenance Log
