location of a cut or other damage

adjust the tire inflation pressure to th e specified level when the tires are cold,

Initialization can be completed in a few minutes. However, in the following cases,
the settings have not been recorded and the system will not operate properly. If
repeated attempts to record tire inflation pressure se ttings are unsu ccessful, have
the vehicle inspected by your Lexus dealer. ●
