sional left and right turns) at
approximately 25 mph (40
km/h) or more for approxi-
mately 10 to 30 minutes.
When initialization is complete, the
inflation pressure of each tire will be
displayed on the multi-information
display.
Even if the vehicle is not driven at
approximately 25 mph (40 km/h) or

more, initialization can be com-
pleted by driving for a long time.
However, if initialization does not
complete after driving for 1 hour or
more, park the vehicle in a safe
place for approximately 20 minutes
and then drive the vehicle again.
■When initializing
●Initialization is performed while
driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Make sure to carry out initializa-
tion after adjusting the tire inflation
pressure.
Also, make sure the tires are cold
before carrying ou t initialization or
tire inflation pressure adjustment.
●The tire pressure warning system
can be initialized by yourself, but
depending on the driving condi-
tions and driving environment, ini-
tialization may take some time to
complete.
■The initialization operation
●If you have accidentally turned the
engine switch to OFF during ini-
tialization, it is not necessary to
restart the initialization again as
initialization will restart automati-
cally when the engine switch has
been turned to ON for the next
time.
●If you accidentally perform initial-
ization when initialization is not
necessary, adjust the tire inflation
pressure to the specified level
when the tires are cold, and con-
duct initialization again.
●While the position of each tire is
being determined and the inflation
pressures are not being displayed
on the multi-inform ation display, if
the inflation pressure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not initialized properly
●In the following si tuations, initial- ization may take longer than usual
to be completed or may not be
possible. Normally, initialization
completes within approximately
30 minutes.
• Vehicle is not driven at approxi-
mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi- cles and system cannot recog-
nize tire pressure warning valve
and transmitters of your vehicle
over those of other vehicles.
• If the vehicle is driven in heavy
traffic or another situation where
other vehicles are driven close by,
it may take time for the system to
recognize the tire pressure warn-
ing valve and transmitters of your
vehicle over those of other vehi-
cles.
●If initialization does not complete
after driving for 1 hour or more,
park the vehicle in a safe place for
approximately 20 minutes and
then drive the vehicle again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so perform the ini-
tialization procedure again from
the beginning.
●In the following situations, initial-
ization will not be started or was
not completed properly and the
system will not operate properly.
Perform the initialization proce-
dure again.
• If, when attempting to start initial-
ization, 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 the inflation pressure of each
tire is still not displayed, have the
vehicle inspected by your Toyota
dealer.

Registering ID codes
4767-3. Do-it-yourself maintenance
■When registering ID codes
●ID code registration is performed
while driving at a vehicle speed of
approximately 25 mph (40 km/h)
or more.
●Before performing ID code regis-
tration, make sure that no wheels
with tire pressure warning valve
and transmitters installed are near
the vehicle.
●Make sure to initialize the tire
pressure warning system after
registering the ID codes. If the
system is initialized before regis-
tering the ID codes, the initialized
values will be invalid.
●ID codes can be registered by
yourself, but depending on the
driving conditions and driving
environment, registration may
take some time to complete.
●As the tires will be warm when
registration is completed, make
sure to allow the tires to cool
before performing initialization.
■Canceling ID code registration
●To cancel ID code registration
after it has been started, select
“Identify Wheel” on the multi-infor-
mation display and press and hold
