The initialization operation
●
Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●
If you have accidentally turned the engine switch to the “LOCK” position
during initialization, it is not necessary to press the reset switch again as
initialization will restart automatically when the engine switch has been
turned to the “ON” position for the next time.
●
If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.
●
While the position of each tire is being determined and the inflation pres-
sures 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 accor-
dance with the conditions 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
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 initial-
ization is not complete after driving approximately 10 to 30 minutes, con-
tinue driving for a while.
If the inflation pressure of each tire is not displayed after driving for
approximately 1 hour, perform the following procedure.
●
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.
However, in the following situations, the tire inflation pressure will not be
recorded and the system will not operate properly. Perform initialization
again.
●
When operating the tire pressure warning reset switch, the tire pressure
warning light does not blink 3 times.
●
After performing initialization, the tire pressure warning light blinks for 1
minute then stays on while driving about 20 minutes.
If the inflation pressure of each tire is still not displayed, have the vehicle
inspected by your Toyota dealer.
