The initialization operation
■
Make sure to carry out initialization after adjusting the tire inflation pressure.
●
Also, make sure the tires are cold before carrying out initialization or tire infla-
tion pressure adjustment.
If you have accidentally turned the "ENGINE START STOP" switch off during
●
initialization, it is not necessary to press the reset switch again as initialization
will restart automatically when the "ENGINE START STOP" switch has been
turned to IGNITION ON mode for the next time.
If you accidentally press the reset switch when initialization is not necessary,
●
adjust the tire inflation pressure to the specified level when the tires are cold,
and conduct initialization again.
Warning performance of the tire pressure warning system
■
The warning of the tire pressure warning system will change in accordance with
driving conditions. 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 warning system has failed
■
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 settings are unsuccessful, have
the vehicle inspected by any authorized Lexus dealer or repairer, or another duly
qualified and equipped professional.
When operating the tire pressure warning reset switch, the tire pressure warn-
●
ing light does not blink 3 times.
After carrying out the initialization procedure, the tire pressure warning light
●
blinks for 1 minute then stays on after driving for 10 minutes.
