EXPLANATION OF MAINTENANCE ITEMS Spark Plugs Replace at specified interval. Install new plugs of the same type as originally equipped. A qualified technician should perform this operation. 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 Chain The timing chain requires no periodic inspection. Tire Rotation See your Owner's Manual for tire rotation requirements. Check tire pressure and check tires for damage and uneven wear. If the vehicle is equipped with a spare tire, 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. Scheduled Maintenance Log 71 MAINTENANCE
