When the message disappears, ini-
tialization is complete.
A message is displayed on the
multi-information di splay. Also, “--”
is displayed for inflation pressure of each tire on the m
ulti-information
display while the tire pressure
warning system determines the
position.
8 Drive straight (with occa-
sional left and right turns) at
approximately 25mph (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 initia lization 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 pres-
sure 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
power switch to OFF during initial-
ization, it is not necessary to
restart the initialization again as
initialization will re start automati-
cally when the power switch has
been turned to ON for the next
time.

Maintenance and care
●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-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 initialization cannot be completed
after performing the above proce-
dure, contact 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 hybrid system.
WARNING
■When initializing the tire pres-
sure warning system
Do not initialize tire inflation pres-
sure without first 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.
