4-3. Do-it-yourself maintenance NOTICE n Repairing or replacing tires, wheels, tire pressure warning valves, transmitters and tire valve caps l When removing or fitting the wheels, tires or the tire pressure warning valve and transmitter, contact your Lexus dealer as the tire pressure warning valves and transmitter may be damaged if not handled correctly. l When replacing tire valve caps, do not use tire valve caps other than those speci- fied. The cap may become stuck. n To avoid damage to the tire pressure warning valves and transmitters 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 Lexus 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. 479) 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 If tire inflation pressures become low while driving Do not continue driving, or your tires and/or wheels may be ruined. 486
