■When rotating the tires
Make sure that the power switch is
off. If the tires are rotated while the
power switch is in ON, the tire posi-
tion information will not be updated.
If this accidentally occurs, either
turn the power switch to off and then
to ON, or initialize the system after
checking that the tire pressure is
properly adjusted.
Your vehicle is equipped with a
tire pressure warning system
that uses tire pressure warning
valves and transmitters to detect
low tire inflation pressure before
serious problems arise.
The tire pressure warning sys-
tem of this vehicle adopts a 2-
type warning system.
 When “Adjust Pressure” is
displayed (Normal Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire infl ation pressure
becomes low due to natural air
leakage or outside temperature. (Ways of coping:
P.561, 605)
 When “Immediately Check
tire when Safe” is displayed
(Emergency Warning)
The tire pressure warning light
comes on and a buzzer sounds
when the tire inflation pressure
becomes low suddenly due to a
blowout. (Ways of coping: P.561,
574)
However, the sys tem may not be
able to detect sudden tire ruptures
(bursting, etc.).
 The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
( P.161)
The illustration us ed is intended as
an example, and may differ from
the image that is actually displayed
on the multi-information display.
■How to change the unit
1 Park the vehicle in a safe
place and turn the power
switch off.
Changing the unit cannot be per-
formed while the vehicle is moving.

■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 pres-
sure 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
transmitters must also be
installed.
When new tire pressure warning
valves and transmitters are
installed, new ID codes must be
registered in the tire pressure
warning computer. ( P.522)
■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. In this
case, after driving for about 20 min-
utes, the tire pressure warning light
blinks for 1 minute and stays on to
indicate a system malfunction.
It is necessary to register the
position of each wheel after per-
forming a tire rotation.
Wheel position registration can
be performed by oneself. Wheel

NOTICE
■Repairing or replacing tires,
wheels, tire pressure warn-
ing valves, transmitters and
tire valve caps
●When removing or fitting the
wheels, tires or the tire pressure
warning valves and transmit-
ters, contact your Toyota dealer
as the tire pressure warning
valves and transmitters may be
damaged if not handled cor-
rectly.
●Make sure to install the tire
valve caps. If the tire valve caps
are not installed, water could
enter the tire pressure warning
valves, corrode the valve, and
cause sticking and air leaks.
●When replacing tire valve caps,
do not use tire valve caps other
than those specified. The cap
may become stuck.
■To avoid damage to the tire
pressure warning valves and
transmitters
When a tire is repaired with liquid
sealants, the tire pressure warn-
ing valve and transmitter may not
operate properly. If a liquid seal-
ant is used, contact your Toyota
dealer or other qualified service
shop as soon as possible. Make
sure to replace the tire pressure
warning valve and transmitter
when replacing the tire. ( P.518)
Registration of the posi-
tion of each wheel after
performing a tire rotation

5207-3. Do-it-yourself maintenance
■If the wheel position cannot be
registered easily
●In the following situations, wheel
position registration may take lon-
ger than usual to be completed or
may not be possible.
• Vehicle is not driven at approxi- mately 25 mph (40 km/h) or more
• Vehicle is driven on unpaved roads
• If wheel position registration does
not complete afte r driving for 1
hour or more, park the vehicle in a
safe place for approximately 15
minutes and then drive the vehicle
again.
●If the vehicle is reversed during
wheel position registration, all
data collected until then will be
cleared. Perform driving again.
In the following situations, it will
be necessary to perform the tire
inflation pressure setting proce-
dure of the tire pressure warning
system.
 When the specified tire infla-
tion pressure has changed,
such as due to carried load,
etc.
 When the tire inflation pres-
sure is changed such as
when the tire size is changed.
If the tire inflation pressure has
been adjusted to the specified
level, perform the tire inflation set-
ting procedure by selecting speci-
fied inflation pressure on the multi-
information display.
When the tire inflation pressure is
to be other than specified, such as
when tires other than the specified
size are used, etc., set the tire infla- tion pressure using the current
pressure. Make sure
to adjust the
tire inflation pressure of each tire to
the appropriate level before per-
forming tire pressure setting. The
tire pressure wa rning system oper-
ates based on this tire inflation
pressure.
■Setting by selecting a spec-
ified tire inflation pressure

tion pressure drops or may illumi-
nate even though the tire inflation
pressure is normal.

5227-3. Do-it-yourself maintenance
■Warning performance of the tire
pressure warning system
●When performing the tire pressure
setting using the current tire infla-
tion pressure, the warning timing
of the tire pressure warning sys-
tem will vary according to the con-
ditions under which tire pressure
setting was performed. Therefore,
a warning may be output even if
the tire inflation pressure drops
slightly or if the tire inflation pres-
sure increases above that when
the tire inflation pressure was set.
●Make sure to perform the tire
pressure setting procedure after
adjusting the tire inflation pres-
sure. Also, make su re the tires are
cold before performing the tire
pressure setting procedure or
adjusting the tire inflation pres-
sure.
■Tire inflation pressure setting
procedure
●If the power switch is turned off
while setting the tire inflation pres-
sure, the next time the power
switch is turned to ON, the setting
procedure will resume and it will
not be necessary to restart the
procedure.
●If the tire inflation pressure setting
procedure is started unnecessar-
ily, adjust the tire inflation pres-
sure to the specified level with the
tires cold and then perform setting
by selecting a specified tire infla-
tion pressure, or perform the tire
inflation pressure setting proce-
dure with the current tire inflation
pressure.
■If the tire inflation pressure can-
not be set easily
●Normally, the tire inflation pres-
sure setting procedure can be
completed in 2 or 3 minutes.
●If the tire pressure warning light
does not blink 3 times when start-
ing the tire inflation pressure set-
ting procedure, the procedure may not have started.
Perform the procedure again from
the beginning.
●If tire inflation
pressure setting
procedure cannot be completed
after performing the above proce-
dure, contact your Toyota dealer.
The tire pressure warning valve
and transmitter is equipped with
a unique ID code. When new
tire pressure warning valves and
transmitters are installed, new
ID codes must be registered in
the tire pressure warning com-
puter.
• ID codes can be registered by
yourself, but depending on
the driving conditions and
driving environment, registra-
tion may take some time to
complete.
• When using a wheel set which all of the ID codes have
already been registered, the
wheel set can be changed in
a short amount of time.
Before performing ID code reg-
istration, make sure that no
wheels with tire pressure warn-
ing valve and transmitters
installed are near the vehicle.
1 Park the vehicle in a safe
place, turn the power switch
off and wait 15 minutes or
more.
