■When replacing the tires and
wheels
If the ID code of the tire pressure
warning valve and transmitter is not
registered, the tire pressure warning
system will not work properly. After
driving for about 20 minutes, the tire
pressure warning light blinks for 1
minute and stays on to indicate a
system malfunction.
■The tire pressure warning
system must be initialized
in the following circum-
stances:
 When rotating the tires. 
When changing the tire.
 After registering the ID codes.
( P.476)
 When changing between two
registered wheel sets.
When the tire pressure warning
system is initialized, the current
tire inflation pressure is set as
the benchmark pressure.
■How to initialize the tire
pressure warning system
1 Park the vehicle in a safe
place and stop the hybrid
system for 20 minutes or
more.
Initialization cannot be performed
while the vehicle is moving.
2Adjust the tire inflation pres-
sure to the specified cold tire
inflation pressure level.
( P.555)

play and the tire pressure warning
light will blink 3 times.
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 multi-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, initializat ion 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 th e vehicle again.
■When initializing
●Initialization is performed 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.
●If you accidentally perform initial-
ization when initia lization is not
necessary, adjust the tire inflation
pressure to the s pecified 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 pressure of a tire
drops, the tire pressure warning
light will come on.
■If the tire pressure warning sys-
tem is not initia lized 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

4767-3. Do-it-yourself maintenance
• 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 si tuations, initial-
ization will not be started or was
not completed properly and the
system will not ope rate properly.
Perform the initialization proce-
dure again.
• If, when attempting to start initial- ization, the tire pressure warning
light does not b link 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 t he 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.
2 Press or of the meter
control switches on the steer-
ing wheel and select .

■When registering ID codes
●ID code registrati on 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 initi alize 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.
