4-3. Do-it-yourself maintenance CAUTION n When inspecting or replacing tires Observe the following precautions to prevent accidents. Failure to do so may cause damage to parts of the drive train, as well as dangerous handling characteristics, which may lead to an accident resulting in death or serious injury. l Do not mix tires of different makes, models or tread patterns. Also, do not mix tires of remarkably different treadwear. l Do not use tire sizes other than those recommended by Lexus. l Do not mix differently constructed tires (radial, bias-belted or bias-ply tires). l Do not mix summer, all season and snow tires. n When initializing the tire pressure warning system Do not press the satellite switch without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal. 4 Maintenance and care NOTICE n Repairing or replacing tires, wheels, tire pressure warning valves and transmit- ters and tire valve caps l When removing or fitting the wheels, tires or the tire pressure warning valves and transmitters, contact your Lexus 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 speci- fied. The cap may become stuck. n To avoid damaging the tire pressure warning valves and transmitters Do not use liquid sealants on flat tires. 395
