Drive straight (with occa-
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 p erformed while
driving at a veh icle 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 out 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 re start automati-
cally when the engine switch has
been turned to ON for the next
time.
●If you accidentally perform initial-

3586-3. Do-it-yourself maintenance
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-information display, if
the inflation pres sure 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 situations, 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 tran smitters 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 veh icle 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 pr essure of each
tire is still not displayed, have the
vehicle inspected by your Toyota
dealer.
Every tire pressure warning
valve and transmitter has a
unique ID code. When replacing
a tire pressure warning valve
and transmitter, it is necessary
to register the ID code.
When registering the ID codes,
perform the following procedure.
1 Park the vehicle in a safe
place, wait for approximately
20 minutes, and then start
the engine.
WARNING
■When initializing the tire pres-
sure warning system
Do not initializing tire inflation
pressure without f irst adjusting
the tire inflation pressure to the
specified level. Otherwise, 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 inflation pressure is
actually normal.

tration, make sure that no wheels
with tire pressur e 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 initializ ed 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” o n the multi-infor-
mation display and press and hold
