4-3. Do-it-yourself maintenance NOTICE n Repairing or replacing tires, wheels, tire pressure warning valves and transmitters and tire valve caps l When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Toyota dealer as the tire pressure warning valve and transmitter may be damaged if not handled correctly. l When replacing tire valve caps, do not use tire valve caps other than those specified. The cap may become stuck. n To avoid damage to the tire pressure warning valves and transmit- ters When a tire is repaired with liquid sealants, the tire pressure warning valve and transmitter may not operate properly. If a liquid sealant is used, contact your Toyota dealer or other qualified service shop as soon as possible. Make sure to replace the tire pressure warning valve and transmitter when replacing the tire (→P. 454) n Driving on rough roads Take particular care when driving on roads with loose surfaces or potholes. These conditions may cause losses in tire inflation pressure, reducing the cushioning ability of the tires. In addition driving on rough roads may cause damage to the tires themselves, as well as the vehicle's wheels and body. n Low profile tires (vehicles with 17-inch tires) Low profile tires may cause greater damage than usual to the wheel when receiving impact from the road surface. Therefore pay attention to the following: l Be sure to use proper tire inflation pressure. If tires are under-inflated, they may be damaged more severely. l Avoid pot holes, uneven pavement, curbs and other road hazards. Failure to do so can lead to severe tire and wheel damage. n If tire inflation pressures become low while driving Do not continue driving, or your tires and/or wheels may be ruined. 462 PRIUS_U (OM47685U) DVD
