Maintenance and care
Select “Change Wheel” then
press and hold until
the tire pressure warning
light blinks slowly 3 times.
Then a message will be dis-
played on the multi-information
display.
When registration is being per-
formed, the tire pressure warn-
ing light will blink for
approximately 1 minute then
illuminate and “- -” will be dis-
played for the inflation pres-
sure of each tire on the multi-
information display.
Drive straight (with occasional left and right turns) at approxi-
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Registration is complete when the tire pressure warning light turns
off and the inflation pressure of eac h tire is displayed on the multi-
information display.
Registration 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. 439)
After registering the ID codes, make sure to initialize the tire pres-
sure warning system. ( →P. 430)

■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.

■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.

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.

Maintenance and care
■Canceling ID code registration (vehicles with a tire inflation pressure
display function)
●To cancel ID code registration afte r it has been started, turn the power
switch off before driving the vehicle.
If the vehicle is driven after ID code registration is started, to cancel reg-
istration, perform the ID code regist ration start procedure again and turn
the power switch off before driving.
●If ID code registration has been canceled, the tire pressure warning light
will blink for approximately 1 minute when the power switch is turned to
ON mode and then illuminate. The tire pressure warning system will be
operational 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 cancelled correctly. To
cancel registration, perform the ID code registration start procedure
again and then turn the power switch off before driving.
■If ID codes are not registered properly (vehicles with a tire inflation
pressure display function)
●In the following situations, ID code registration 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 minutes to complete ID
code registration.)
If ID code registration is not complete after driving for approximately 30
minutes, continue driving for a while.
• If the vehicle is driven on an unpaved road, it may take longer than normal to comple te registration.
• If the vehicle is backed up while performing registration, data col- lected during registration 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 a wheel with a tire pressure wa rning valve and transmitter installed
is inside or near the vehicle, registration of the ID codes for the
installed wheels may not be possible.
If ID registration is not complete after driving for approximately 1 hour,
park the vehicle in a safe place for approximately 20 minutes and then
perform the ID code registration procedure again.
