Repairing or replacing tires, wheels, tire pressure warning valves, transmit-

ters and tire valve caps

When removing or fitting the wheels, tires or the tire pressure warning

valves and transmitter, contact any authorized Lexus dealer or repairer, or

another duly qualified and equipped professional as the tire pressure

warning valves and transmitters may be damaged if not handled correctly.

When replacing tire valve caps, do not use tire valve caps other than those

specified. The cap may become stuck.

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

any authorized Lexus dealer or repairer, or another duly qualified and

equipped professional 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. 498)

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.

If tire inflation pressure of each tire becomes low while driving

Do not continue driving, or your tires and/or wheels may be ruined.
