more for approximately 10 to 30
minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information dis-
play.
Even if the vehicle is not driven at
approximately 40 km/h (25 mph) or
more, initialization can be completed by
driving for a long time. However, if ini-
tialization does not complete after driv-
ing for 1 hour or more, park the vehicle
in a safe place for approximately 20
minutes and then drive the vehicle
again.
QWhen initializing
OInitialization is performed while driving
at a vehicle speed of approximately
40 km/h (25 mph) or more.
OMake 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.
OThe tire pressure warning system can
be initialized by yourself, but depend-
ing on the driving conditions and driv-
ing environment, initialization may
take some time to complete.
QThe initialization operation
OIf you have accidentally turned the
power switch to OFF during initializa-
tion, it is not necessary to restart the
initialization again as initialization will
restart automatically when the power
switch has been turned to ON for the
next time.
OIf you accidentally perform initializa-
tion when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.
OWhile the position of each tire is being
determined and the inflation pres-
sures are not being displayed on the
multi-information display, if the infla-tion pressure of a tire drops, the tire
pressure warning light will come on.
QIf the tire pressure warning system
is not initialized properly
OIn the following situations, initialization
may take longer than usual to be com-
pleted or may not be possible. Nor-
mally, initialization completes within
approximately 30 minutes.
• Vehicle is not driven at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles.
• If the vehicle is driven in heavy traffic
or another situation where other vehi-
cles are driven close by, it may take
time for the system to recognize the
tire pressure warning valve and trans-
mitters of your vehicle over those of
other vehicles.
OIf initialization does not complete after
driving for 1 hour or more, park the
vehicle in a safe place for approxi-
mately 20 minutes and then drive the
vehicle again.
OIf the vehicle is reversed during initial-
ization, the data up to that point is
reset, so perform the initialization pro-
cedure again from the beginning.
OIn the following situations, initialization
will not be started or was not com-
pleted properly and the system will not
operate properly. Perform the initial-
ization procedure again.
• If, when attempting to start initializa-
tion, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven
for about 20 minutes after performing
initialization, the tire pressure warning
light blinks for approximately 1 minute
and then illuminates.
If initialization cannot be completed after
performing the above procedure, con-
tact any authorized Toyota retailer or
Toyota authorized repairer, or any reli-

pressure warning light will go off and
the inflation pressure of each tire will be
displayed on the multi-information dis-
play.
Even if the vehicle is not driven at
approximately 40 km/h (25 mph) or
more, registration can be completed by
driving for a long time. However, if reg-
istration does not complete after driving
for 1 hour or more, perform the proce-
dure again from the beginning.
7Initialize the tire pressure warn-
ing system. (P.468)
QWhen registering ID codes
OID code registration is performed
while driving at a vehicle speed of
approximately 40 km/h (25 mph) or
more.
OBefore performing ID code registra-
tion, make sure that no wheels with
tire pressure warning valve and trans-
mitters installed are near the vehicle.
OMake sure to initialize the tire pres-
sure warning system after registering
the ID codes. If the system is initial-
ized before registering the ID codes,
the initialized values will be invalid.
OID codes can be registered by your-
self, but depending on the driving con-
ditions and driving environment,
registration may take some time to
complete.
OAs the tires will be warm when regis-
tration is completed, make sure to
allow the tires to cool before perform-
ing initialization.
QCanceling ID code registration
OTo cancel ID code registration after it
has been started, select “Identifying
Each Wheel & Position” on the multi-
information display and press and
hold again.
OIf ID code registration has been can-
celed, the tire pressure warning light
will blink for approximately 1 minute
when the power switch is turned to ON and then illuminate. The tire pres-
sure warning system will be opera-
tional when the tire pressure warning
light turns off.
OIf the warning light does not turn off
even after several minutes have
elapsed, ID code registration may not
have been canceled correctly. To can-
cel registration, perform the ID code
registration start procedure again and
then turn the power switch off before
driving.
QIf ID codes are not registered prop-
erly
OIn the following situations, ID code
registration may take longer than
usual to be completed or may not be
possible. Normally, registration com-
pletes within approximately 30 min-
utes.
If ID code registration is not complete
after driving for approximately 30 min-
utes, continue driving for a while.
• Vehicle is not parked for approxi-
mately 20 minutes or more before
driving
• Vehicle is not driven at approximately
40 km/h (25 mph) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehicles
and system cannot recognize tire
pressure warning valve and transmit-
ters of your vehicle over those of other
vehicles
• Wheel with tire pressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete after
driving for 1 hour or more, perform the
ID code registration procedure again
from the beginning.
OIf the vehicle is reversed during regis-
tration, the data up to that point is
reset, so perform the registration pro-
cedure again from the beginning.
OIn the following situations, ID code
registration will not be started or was
not completed properly and the sys-
tem will not operate properly. Perform
