Initialization procedure
●
Make sure to carry out initializa-
tion 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
power switch off during initializa-
tion, it is not necessary to press
the reset switch again as initializa-
tion will restart automatically when
the power switch to ON for the
next time.
●
If initialization has accidentally
been started when it is not neces-
sary, adjust the tire inflation pres-
sure to the specified level when
the tires are cold, and then per-
form 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 follow-
ing cases, the settings have not
been recorded and the system will
not operate properly. If repeated
attempts to record tire inflation pres-
sure settings are unsuccessful,
have the vehicle inspected by your
Toyota dealer.
●
When attempting to start initializa-
tion, 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 min-
ute.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When replac-
ing a tire pressure warning valve
and transmitter, it is necessary
to register the ID code. Have the
ID code registered by your
Toyota dealer.
Your vehicle is equipped with
tire pressure warning system
with the function to have ID
codes registered for a second
wheel set, for example a winter
set, by Toyota dealer.
After registration of a second
wheel set, either of these two
wheel sets can be selected for
usage with the tire pressure
warning system.
WARNING
■
When initializing the tire pres-
sure warning system
Do not initialize the tire pressure
warning system without first
adjusting the tire inflation pres-
sure to the specified level. Other-
wise, 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 infla-
tion pressure is actually normal.
