Maintenance and care
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valve and trans mitters to detect low tire inflation
pressure before serious problems arise.
Vehicles without a tire inflat ion pressure display function
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 .
7-inch display: Select and then press and hold .

Select “Set Pressure” then
press and hold until
the tire pressure warning
light blinks 3 times.
Then a message will be dis-
played on the multi-information
display.
Vehicles with a tire inflation
pressure display function: “- -”
will be displayed on the multi-
information display for the
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)
4.2-inch display: Select “Vehicle Settings” and then press .
7-inch display: Select and then press and hold .
Select “TPWS” and then press .

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

■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.
