Maintenance and care

The initialization operation
●Make sure to carry out in
itialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold be fore 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 the “ON” position (vehi-
cles without a smart key system) or IGNITION ON mode (vehicles with a
smart key system) for the next time.
●If you accidentally press the reset s witch when initialization is not neces-
sary, adjust the tire inflation pressu re to the specified level when the
tires are cold, and conduct initialization again.
■Warning performance of the ti re pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with driving conditions. For th is 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 pr essure 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 oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●When operating the initialization of th e system, the tire pressure warning
light does not blink 3 times and the setting message does not appear on
the multi-information display.
●After driving for a certain period of time since the initialization has been
completed, the warning light comes on after blinking for 1 minute.
