●Make sure to carry out initialization after adjusting the tire inflation pressure. Also, make sure the tires are cold before carry ing out initialization or tire inflation pres-
sure adjustment.
●If you have accidentally turned the power switch off during initialization, it is not neces- sary to manually restart the initialization ag ain, as initialization will restart automatically
the next time the power switch is turned to ON mode.
●If you accidentally perform in itialization when initialization is not necessary, adjust the tire inflation pressure to the specified leve l when the tires are cold, and conduct initial-
ization again.
■Warning performance of the tire pressure warning system (if equipped)
The warning of the tire pressure warning syst em will change in accordance with the con-
ditions under which it was initialized. For this reason, the system may give a warning even if the tire pressure does not reach a low enough level, or if the pressure is higher than the pressure that was adjusted to when the system was initialized.
■When initialization of the tire pressure warn ing system has failed (vehicles with the tire pressure warning system)
Initialization can be co mpleted in a few minutes. However, in the following cases, the set-
tings have not been recorded and the syst em will not operate properly. If repeated attempts to record tire inflation pressure settings are unsuccessful, have the vehicleinspected by any authorized Lexus retailer or Lexus authorized repairer, or any reliable
repairer.
●The initialization message is not displayed on the multi-information display when per- forming initialization.
●After carrying out the initializat ion procedure, the tire pressure warning light blinks for 1 minute then stays on after driving for 20 minutes.
■Registering ID codes (vehicles with the tire pressure warning system)
The ID codes of the tire pressure warning valve and transmitters for two sets of wheels can be registered.
It is not necessary to register the ID codes wh en replacing normal tires with snow tires, if the ID codes for the wheels of both normal tires and snow tires are registered before-hand.
For information about changing ID codes, ask any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer.
