■ Initialization procedure

  • 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 pressure adjustment.
  • If you have accidentally turned the engine switch off during initialization, it is not necessary to press the reset switch again as initialization will restart automatically when the engine switch to ON for the next time.
  • If initialization has accidentally been started when it is not necessary, adjust the tire inflation pressure to the specified level when the tires are cold, and then perform the initialization procedure again.

■ 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 your Toyota dealer.

  • When attempting to start initialization, the tire pressure warning light does not blink 3 times.
  • After driving for a certain period of time since the initialization has been completed, the warning light comes on after blinking for 1 minute.

Do not initialize the tire pressure warning system without first adjusting the tire inflation pressure to the specified level. Otherwise, the tire pressure warning light may not come on even if the tire inflation pressure is low, or it may come on when the tire inflation pressure is actually normal.
