●“READY” indicator is not illumi-
nated.
●The shift lever is in a range other
than D or S.
■Outside temperature display
●In the following si tuations, the cor-

be displayed, or the display may
take longer than normal to
change.
• When stopped, or driving at low speeds (less than 12 mph [20
km/h])
• When the outside temperature has changed suddenly (at the
entrance/exit of a garage, tunnel,
etc.)
●When “--” or “E” is displayed, the
system may be malfunctioning.
Take your vehicle to your Toyota
dealer.
●Displays the outside temperature
within the range of -40°F (-40°C)
to 122°F (50°C).
●When the outside temperature is
approximately 37°F (3°C) or

indicator will flash for approxi-
mately 10 seconds , then stay on.

the “ODO TRIP” switch.
When the trip meter is dis-
played, pressing and holding the
switch will reset the trip meter.
WARNING
■The information display at
low temperatures
Allow the interior of the vehicle to
warm up before using the liquid
crystal information display. At
extremely low temperatures, the
display monitor may respond
slowly, and display changes may
be delayed.
For example, there is a lag
between the driver’s shifting and
the new shift range appearing on
the display. This lag could cause
the driver to downshift again,
causing rapid and excessive
engine braking and possibly an
accident resulting in death or
injury.
NOTICE
■To prevent damage to the
engine and its components
The engine may be overheating if
the engine coolant temperature
gauge is in the red zone (“H”). In
this case, immediately stop the
vehicle in a safe place, and check
the engine after it has cooled
completely. ( P.511)

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 th e 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 out
initialization or tir e 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 initia lization again as
initialization will restart automati-
cally when the power switch has
been turned to ON for the next
time.
●If you accidentally perform initial-
ization when initi alization 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 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
• Vehicle is driven on unpaved roads
• Vehicle is driven near other vehi- cles and system cannot recog-
nize tire pressure warning valve
and transmitters o f 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 f or the system to
recognize the ti re 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 v ehicle again.
●If the vehicle is reversed during
initialization, the data up to that
point is reset, so p erform 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 oper ate 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

Maintenance and care
●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
“Identifying Each Wheel & Posi-
tion” on the multi-information dis-
play and press and hold “OK”
again.
●If ID code registration has been
canceled, the tire pressure warn-
ing light will blink for approxi-
mately 1 minute when the power
switch is turned to ON and then
illuminate. The tir e pressure warn-
ing system will be operational
when the tire pressure warning
light turns off.
●If the warning light does not turn
off even after se veral minutes
have elapsed, ID code registration
may not have bee n canceled cor-
rectly. To cancel registration, per-
form the ID code registration start
procedure again and then turn the
power switch off before driving.
■If ID codes are not registered
properly
●In the following situations, ID code
registration may take longer than
usual to be completed or may not
be possible. Normally, registra-
tion completes within approxi-
mately 30 minutes.
If ID code registration is not com-
plete after driving for approxi-
mately 30 minutes, continue
driving for a while. • Vehicle is not pa
rked for approxi-
mately 20 minutes or more before
driving
• 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 o f your vehicle
over those of other vehicles
• Wheel with tire p ressure warning
valve and transmitter installed is
inside or near the vehicle
If registration does not complete
after driving for 1 hour or more, per-
form the ID code registration proce-
dure again from the beginning.
●If the vehicle is reversed during
registration, the data up to that
point is reset, so p erform the reg-
istration procedure again from the
beginning.
●In the following situations, ID code
registration will not be started or
was not completed properly and
the system will not operate prop-
erly. Perform the ID code registra-
tion procedure again.
• If, when attempt ing to start ID
code registration, the tire pressure
warning light does not blink slowly
3 times.
• If, when the veh icle has been
driven for about 20 minutes after
performing ID code registration,
the tire pressure warning light
blinks for approximately 1 minute
and then illuminates.
If the ID codes cannot be registered
even when performing the above
procedure, contact your Toyota
dealer.
