4-3. Do-it-yourself maintenance n When replacing wheels The wheels of your Toyota are equipped with tire pressure warning valves and transmitters that allow the tire pressure warning system to provide advanced warning in the event of a loss in tire inflation pressure. Whenever wheels are replaced, the tire pressure warning valves and transmitters must be switched over from the old wheels. (→P. 380) 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. 4 NOTICE Maintenance and care n Replacing tire pressure warning valves and transmitters l Because tire repair or replacement may affect the tire pressure warn- ing valves and transmitters, make sure to have tires serviced by your Toyota dealer. In addition, make sure to purchase your tire pressure warning valves and transmitters at your Toyota dealer. l Ensure that only genuine Toyota wheels are used on your vehicle. Tire pressure warning valves and transmitters may not work properly with non-genuine wheels. 393 PRIUS_U_(L/O_0802)
