fied level and initialize the tire pressure warning system again.

When the initialization of the tire pressure warning system has
failed
Initialization can be completed in a few minutes. However, in the follow-
ing 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 your Toyota
dealer.

When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.

After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for about 20
minutes.

Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation pres-
sure checks. Make sure to check tire inflation pressure as part of your rou-
tine of daily vehicle checks.
