EXPLANATION OF MAINTENANCE ITEMS Timing Chain The timing chain requires no periodic inspection. 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. Tire Rotation Tires should be rotated according to the instructions in your Owner's Manual. When rotating tires, check tire pressure and check tires for damage and uneven wear. If the spare is not rotated, check the condition and pressure of the spare. Transfer Case Oil Check for correct oil level and inspect each component for signs of leakage. If you discover any leakage, have it repaired immediately by a qualified technician. For correct oil, refer to your Owner's Manual. Transmission The 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 precedures in Lexus service and repair publications. MAINTENANCE 72 Scheduled Maintenance Log
