Front
To equalize tire wear and help extend
tire life, Toyota recommends that tire
rotation is carried out approximately
every 10000 km (6000 miles).
When rotating front and rear tires which
have different tire inflation pressures,
do not fail to initialize the tire pressure
warning system after tire rotation.
Your vehicle is equipped with a tire
pressure warning system that uses
tire pressure warning valves and
transmitters to detect low tire infla-
tion pressure before serious prob-
lems arise.
The tire pressure warning system
of this vehicle adopts a 2-type
warning system.
zWhen “Adjust Pressure” is dis-
played (Normal Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is an unknown level of low tire
pressure with the appearance of the tire
due to natural air leakage as well as the
pressure lowering due to changes in
the pressure according to the outside
temperature. (Ways of coping: →P.375,
417)
zWhen “Immediately Check tire
when Safe” is displayed (Emer-
gency Warning)
A warning with the tire pressure warn-
ing light and warning buzzer when
there is a known level of low tire pres-sure with the appearance of the tire due
to pressure suddenly lowering. (Ways
of coping: →P.379, 389)
However, the system may not be able
to detect sudden tire ruptures (bursting,
etc.).
The tire pressure detected by the
tire pressure warning system can
be displayed on the multi-informa-
tion display.
The unit can be changed.
■How to change the unit
1Park the vehicle in a safe place
and turn the engine switch off.
Changing the unit cannot be performed
while the vehicle is moving.

■Routine tire inflation pressure
checks
The tire pressure warning system does
not replace routine tire inflation pressure
checks. Make sure to check tire inflation
pressure as part of your routine of daily
vehicle checks.
■Tire inflation pressure
●It may take a few minutes to display
the tire inflation pressure after the
engine switch is turned to ON. It may
also take a few minutes to display the
tire inflation pressure after inflation
pressure has been adjusted.
●Tire inflation pressure changes with
temperature. The displayed values
may also be different from the values
measured using a tire pressure
gauge.
■Situations in which the tire pres-
sure warning system may not oper-
ate properly
●In the following cases, the tire pres-
sure warning system may not operate
properly.
• If non-genuine Toyota wheels are
used.
• A tire has been replaced with a tire
that is not an OE (Original Equipment)
tire.
• A tire has been replaced with a tire
that is not of the specified size.
• Tire chains, etc. are equipped.
• An auxiliary-supported run-flat tire is
equipped.• If a window tint that affects the radio
wave signals is installed.
• If there is a lot of snow or ice on the
vehicle, particularly around the wheels
or wheel housings.
• If the tire inflation pressure is
extremely higher than the specified
level.
• If tires not equipped with tire pressure
warning valves and transmitters are
used.
• If the ID code on the tire pressure
warning valves and transmitters is not
registered in the tire pressure warning
computer.
●Performance may be affected in the
following situations.
• Near a TV tower, electric power plant,
gas station, radio station, large dis-
play, airport or other facility that gen-
erates strong radio waves or electrical
noise.
• When carrying a portable radio, cellu-
lar phone, cordless phone or other
wireless communication device.
●When the vehicle is parked, the time
taken for the warning to start or go off
could be extended.
●When tire inflation pressure declines
rapidly for example when a tire has
burst, the warning may not function.
■Warning performance of the tire
pressure warning system
The warning of the tire pressure warning
system will change in accordance with
driving conditions. For this reason, the
system may give a warning even if the
tire pressure does not reach a low
enough level, or if the pressure is higher
than the pressure that was adjusted to
when the system was initialized.
When replacing tires or wheels, tire
pressure warning valves and trans-
mitters must also be installed.

and turn the engine switch off.
Initialization cannot be performed while
the vehicle is moving.
2Adjust the tire inflation pressure
to the specified cold tire inflation
pressure level. (→P.417)
Make sure to adjust the tire pressure to
the specified cold tire inflation pressure
level. The tire pressure warning system
will operate based on this pressure
level.
3Turn the engine switch to ON.

until the tire pressure warn-
ing light blinks 3 times.
Then a message will be displayed on
the multi-information display. “--” will be
displayed on the multi-information dis-
play for the inflation pressure of each tire while initialization is being per-
formed.
8Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Initialization is complete when the posi-
tion of each tire is determined and the
inflation pressure of each tire is dis-
played on the multi-information display.
Initialization may take longer than
approximately 1 hour in certain situa-
tions, such as when the vehicle is
stopped for a long time at traffic lights,
etc. (→P.337)
■Initialization procedure
●Make sure to carry out initialization
after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold
before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the
engine switch off during initialization, it
is not necessary to press the reset
switch again as initialization will
restart automatically when the engine
switch is turned to ON the next time.
●If you accidentally press the reset
switch when initialization is not neces-
sary, adjust the tire inflation pressure
to the specified level when the tires
are cold, and conduct initialization
again.

5Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Registration is complete when the tire
pressure warning light turns off and the
inflation pressure of each tire is dis-
played on the multi-information display.
Registration may take longer than
approximately 1 hour in certain situa-
tions, such as when the vehicle is
stopped for a long time at traffic lights,
etc. (→P.337)
After registering the ID codes, make
sure to initialize the tire pressure warn-ing system. (→P.335)
■When registering ID codes
●Before performing ID code registra-
tion, make sure that no wheels with
tire pressure warning valve and trans-
mitters installed are near the vehicle.
●Make sure to initialize the tire pres-
sure warning system after registering
the ID codes. If the system is initial-
ized before registering the ID codes,
the initialized values will be invalid.
●As the tires will be warm when regis-
tration is completed, make sure to
allow the tires to cool before perform-
ing initialization.
■Canceling ID code registration
●To cancel ID code registration after it
has been started, turn the engine
switch off before driving the vehicle.
If the vehicle is driven after ID code
registration is started, to cancel regis-
tration, perform the ID code registra-
tion start procedure again and turn the
engine switch off before driving.
●If ID code registration has been can-
celed, the tire pressure warning light
will blink for approximately 1 minute
when the engine switch is turned to
ON mode and then illuminate. The tire
pressure warning system will be oper-
ational when the tire pressure warning
light turns off.
●If the warning light does not turn off
even after several minutes have
elapsed, ID code registration may not
have been canceled correctly. To can-
cel registration, perform the ID code
registration start procedure again and
then turn the engine switch off before
driving.
■If ID codes are not registered prop-
erly
●In the following situations, ID code
registration may take longer than
usual to be completed or may not be
