◆Installing tire pressure warning valves and transmitters
When replacing the tires or wheels, the tire pressure warning valve
and transmitters must be insta lled to the wheels which will be
installed to the vehicle.
When new tire pressure warning valve and transmitters are
installed, new ID codes must be registered in the tire pressure
warning computer and the tire pr essure warning system must be
initialized. ( →P. 432)
◆Initializing the tire pressure warning system
■The tire pressure warning system must be initialized in the fol-
lowing circumstances:
● When the tire inflation pressure is changed such as when chang-
ing traveling speed or load weight.
● When the tire inflation pressure is changed such as when the tire
size is changed.
● When rotating the tires.
● Vehicles with a tire inflation pr essure display function: After per-
forming the transmitter ID co de registration procedure. (→P. 432)
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
Park the vehicle in a safe place and turn the power switch off.
The initialization procedure cannot be started while the vehicle is
moving.
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. ( →P. 532)
Make sure to adjust the tire pressu re to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
Turn the power switch to ON mode.
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the steer-
ing wheel. ( →P. 105, 119).

◆Registering ID codes
Vehicles without a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. In addition to the set of ti re pressure warning system sensor
ID codes initially registered to th e vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes can
be registered at your Toyota deal er. When 2 sets of ID codes have
been registered, either ID code set can be selected.
Vehicles with a tire inflat ion pressure display function
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 re gister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the mu lti-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are registered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch display)
or (7-inch display) of the multi-information display. It is not nec-
essary to reregister the ID codes each time the wheels are
changed.
For information regarding changing the registered ID codes for an
ID code set, contact your Toyota dealer.
■How to register the ID codes (vehicles with a tire inflation pres-
sure display function)
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the steer-
ing wheel. ( →P. 105, 119)

■Situations in which the tire pressure warning system may not oper-
ate properly
●In the following situations, the tire pressure warning system may not
operate properly.
• If non-genuine Toyota wheels are used.
• If a tire has been replaced with a tire that is not an OE (Original
Equipment) tire.
• If a tire has been replaced with a tire that is not of the specified size.
• If tire chains, etc. are installed.
• If a window tint that affects 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 mu ch higher than the specified level.
• If wheels not equipped with tire pressure warning valve and transmit- ter are used.
• If the ID codes of the tire pressure warning valve and transmitters are not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• When driving near a TV tower, electric power plant, gas station, radiostation, large display, airport or other facility that generates strong
radio waves or electrical noise
• When carrying a portable radio, cellular phone, cordless phone or other wireless communication device
Vehicles with a tire inflation pressure display function: If tire position
information is not correctly displayed due to the radio wave conditions,
the display may be corrected by changing the location of the vehicle as
the radio wave conditions may change.
●When the vehicle is stopped, the time taken for the warning to start or
turn off may be longer.
●When the inflation pressure of a tire drops rapidly, for example when a
tire has burst, the warning may not operate.

Maintenance and care
■Initialization procedure
●Make sure to perform the initialization procedure after adjusting the tire
inflation pressure.
Also, make sure the tires are cold before performing the initialization
procedure or adjusting the tire inflation pressure.
●If the power switch is turned off during initialization, it is not necessary to
restart the initializatio n procedure from the beginning as it will begin
automatically when the power switch is turned back to ON mode.
●If initialization has accidentally been started when it is not necessary,
adjust the tire inflation pressure to the specified level when the tires are
cold and then perform the initialization procedure again.
●Vehicles with a tire inflation pressure display function: While the position
of each tire is being determined and the inflation pressures are not being
displayed on the multi-information displa y, if the inflation pressure of a
tire drops, the ti re pressure warnin g light will come on.
■Warning performance of the ti re pressure warning system
The warning of the tire pressure warning system will change in accor-
dance with the conditions under which it was initialized. 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.
■If the tire pressure warning sy stem is not initialized properly
Vehicles without a tire inflation pressure display function
Initialization can be completed in a few minutes. However, in the following
cases, the settings have not been recorded and the system will not oper-
ate properly. If repeated attempts to record tire inflation pressure settings
are unsuccessful, have the vehicle inspected by your Toyota dealer.
●If initialization is attempted and the tire pressure warning light does not
blink 3 times.
●If, when the vehicle has been driven for about 20 minutes after perform-
ing initialization, the tire pressure warning light blinks for approximately
1 minute and th en illuminates.
