4-3. Do-it-yourself maintenance CAUTION n When replacing wheels l Do not use wheels that are a different size from those recommended in the Owner's Manual, as this may result in loss of handling control. l Never use an inner tube in a leaking wheel which is designed for a tubeless tire. Doing so may result in an accident, causing death or serious injury. n Wheel bolts Observe the following precautions to reduce the risk of death or serious injury: l Do not over tighten. l Never use oil or grease on the wheel bolts. Oil and grease may cause the wheel bolts to be excessively tightened, leading to bolt or disc wheel damage. In addition, the oil or grease can cause the wheel bolts to loosen and the wheel may fall off, causing a serious accident. Remove any oil or grease from the wheel bolts. l If there are any cracks or deformations in the wheel bolts, or if the surface treat- ment becomes worn, have the wheel bolts replaced at your Lexus dealer. Failure to follow these precautions could cause the wheel bolts to loosen and the tire to fall off, resulting in death or serious injury. l If the wheels are frequently removed and installed due to circuit driving etc., Lexus recommends periodic changing of the wheel bolts. NOTICE n Replacing tire pressure warning valves and transmitters l Because tire repair or replacement may affect the tire pressure warning valves and transmitters, make sure to have tires serviced by your Lexus dealer or other qualified service shop. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Lexus dealer. l Ensure that only genuine Lexus wheels are used on your vehicle. Tire pressure warning valves and transmitters may not work properly with nongenuine wheels. 282
