Maintenance and care
■ 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 inflation pres-
sure adjustment.
● If you have accidentally turned the engine switch off during initialization, it is not neces-
sary to manually restart the initialization again, as initialization will restart automatically
the next time the engine switch is turned to IGNITION ON mode.
● If you accidentally perform initialization when initialization is not necessary, adjust the
tire inflation pressure to the specified level when the tires are cold, and conduct initial-
ization again.
● While the position of each tire is being determined and the inflation pressures are not
being displayed on the multi-information display, if the inflation pressure of a tire drops,
the tire pressure warning light will come on.
■ Warning performance of the tire pressure warning system
The warning of the tire pressure warning system 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 warning system has failed
● Do not move the vehicle backward during initialization. Initialization is started again
from the beginning and it may take longer than usual.
● Initialization may take longer to complete if the vehicle is driven on an unpaved road.
When performing initialization, drive on a paved road if possible. Depending on the
driving environment and condition of the tires, initialization will be completed in
approximately 10 to 30 minutes.
• If initialization is not complete after driving approximately 30 minutes, continue
driving for a while.
• If initialization is not complete after driving approximately 1 hour, park the vehicle in
a safe place for approximately 20 minutes. Then drive straight (with occasional left
and right turns) at approximately 25 mph (40 km/h) or more
* for approximately 10
to 30 minutes.
If initialization is still not complete, have the vehicle inspected by your Lexus dealer.
*: Except when making a left/right turn
● In the following situations, the tire inflation pressure will not be recorded and the system
will not operate properly. Perform initialization again.
• If, when attempting to start initialization, the tire pressure warning light does not
blink 3 times.
• If, when the vehicle has been driven for about 20 minutes after performing initializa-
tion, the tire pressure warning light blinks for approximately 1 minute and then illumi-
nates.
