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 valves and transmitters, contact your Toyota dealer as the tire pressure warning valves and transmitters 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 damaging the tire pressure warning valves and transmit- ters Do not use liquid sealants on flat tires. 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. 274
