If the tire pressure drops below a predetermined level, the driver is
warned by a screen display and a warning light. ( →P. 483)
Vehicles with a tire inflat ion pressure display function
● The tire pressure detected by the tire pressure warning system can
be displayed on the multi-information display.
● If the tire pressure drops below a predetermined level, the driver is
warned by a screen display and a warning light. ( →P. 483)

◆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).
4.2-inch display: Select “Vehicle Settings” and then press .

inflation pressure of each tire
while initialization is being per-
formed.
Vehicles with a tire inflation pressure display function: Drive
straight (with occasional left and right turns) at approximately 25
mph (40 km/h) or more for approximately 10 to 30 minutes.
Initialization is complete when the position of each tire is determined
and the inflation pressure of each ti re is displayed on the multi-infor-
mation display.
Initialization may take longer than approximately 1 hour in certain
situations, such as when the vehicle is stopped for a long time at
traffic lights, etc. ( →P. 437)

◆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)

■When to replace your vehicle’s tires
Tires should be replaced if:
●The treadwear indicators are showing on a tire.
●You have tire damage such as cuts, splits, cracks deep enough to
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or cannot be properly repaired due to the size
or location of a cut or other damage
If you are not sure, consult with your Toyota dealer.
■Replacing tires and wheels
If the ID codes of the tire pressure warning valve and transmitters are not
registered, the tire pres sure warning system will not work properly. In this
case, after driving for about 20 minute s, the tire pressure warning light will
blink for approximately 1 minute and then illuminate to indicate a system
malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified technician even
if it has seldom or never been used or damage is not obvious.
■Routine tire inflation pressure checks
The tire pressure warning system does not replace routine tire inflation
pressure checks. Make su re to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (vehicle s with 18-inch wheels)
Generally, low profile tires will wear mo re rapidly and tire grip perfor-
mance will be reduced on snowy and/ or icy roads when compared to
standard tires. Be sure to use snow tires on snowy and/or icy roads and
drive carefully at a speed appropriate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of the re placement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axle or the
rear axle, whichever is greater.
For the GAWR, see the Certification
Label. For the maximum load of the tire,
see the load limit at maximum cold tire
inflation pressure mentioned on the
sidewall of the tire. ( →P. 538)

Maintenance and care
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Since summer tires do not have the same
traction performance as snow tires, summer tires are inadequate for
driving on snow-covered or icy ro ads. For driving on snow-covered
roads or icy roads, the use of snow tires is recommended. When install-
ing snow tires, be sure to replace all four tires.
●All season tires
All season tires are designed to provide better traction in snow and to
be adequate for driving in most winter conditions as well as for use
year-round. All season tires, however, do not have adequate traction
performance compared with snow tires in heavy or loose snow. Also, all
season tires fall short in acceleration and handling performance com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend using
snow tires. If you need snow tires, select tires of the same size, con-
struction and load capacity as the or iginally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construction. Do not install studded tires without
first checking local regulations fo r possible restrictions. Snow tires
should be installed on all wheels. ( →P. 338)
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tire s as snow tires is lost.

4366-3. Do-it-yourself maintenance
■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.

4386-3. Do-it-yourself maintenance
Vehicles with a tire inflation pressure display function
●In the following situations, initialization may take longer than usual to be
completed or may not be possible. (Usually, the vehicle will need to be
driven for approximately 10 to 30 mi nutes to complete initialization.)
If initialization is not complete af ter driving approximately 30 minutes,
continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer to com-
plete initialization.
• If the vehicle is backed up while performing initialization, data col-
lected during initialization will be cleared and it will take longer than
normal to complete.
• 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 recog-
nize the tire pressure warning valve and transmitters of your vehicle
over those of other vehicles.
If initialization is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
drive the vehicle again.
●In the following situations, initialization will not be started or was not
completed properly and the system w ill not operate properly. Perform
the initialization procedure again.
• If, when attempting to start initializ ation, the tire pressure warning light
does not blink 3 times.
• If, when the vehicle has been driven for about 20 minutes after per-
forming initialization, th e tire pressure warning light blinks for approxi-
mately 1 minute and then illuminates.
●If initialization cannot be complet ed after performing the above proce-
dure, contact your Toyota dealer.
■When registering ID codes (vehicles with a tire inflation pressure dis-
play function)
●Before performing ID code registrati on, make sure that no wheels with
tire pressure warning valve and transmitters installed are near the vehi-
cle.
●Make sure to initialize the tire pressure warning system after registering
the ID codes. If the system is initia lized before registering the ID codes,
the initialized va lues will be invalid.
●As the tires will be warm when regist ration is completed, make sure to
allow the tires to cool befo re performing initialization.
