Doing so may cause streaking on the vehicle's painted surfaces, as well as
damaging the pump leading to problems of the washer fluid not spraying.
■Diluting washer fluid
Dilute washer fluid with water as necessary.
Refer to the freezing temperatures listed on the label of the washer fluid bot-
tle.

Tire pressure warning system
Your vehicle is equipped with a tire pressure warning system that uses
tire pressure warning valve and transmitters to detect low tire inflation
pressure before serious problems arise.
● The tire pressure detected by
the tire pressure warning sys-
tem can be displayed on the
multi-information display.
*: If equipped
*
● If the tire pressure drops below
a predetermined level, the
driver is warned by a screen
display and a warning light.

6-3. Do-it-yourself maintenance
◆ Installing tire pressure warning valve and transmitters
When replacing the tires or wheels, the tire pressure warning valve
and transmitters must be installed 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 pressure warning system must be
initialized. (P. 439)
◆ 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.
● After performing the transmitter ID code registration procedure.
(P. 439)
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 engine switch off.
1
The initialization procedure cannot be started while the vehicle is
moving.
2
Adjust the tire inflation pressure to the specified cold tire inflation
pressure level. (P. 540)
Make sure to adjust the tire pressure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will operate
based on this pressure level.
3
Start the engine. (P. 207, 210)

performed.
Drive straight (with occasional left and right turns) at approxi-
8
mately 25 mph (40 km/h) or more for approximately 10 to 30 min-
utes.
Initialization is complete when the position of each tire is determined
and the inflation pressure of each tire 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. 444)
◆ Registering ID codes
6
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 register the ID codes.
The ID codes can be registered on
of the multi-information dis-
play.

■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 code of the tire pressure warning valve and transmitter is not reg-
istered, the tire pressure warning system will not work properly. After driv-
ing for about 20 minutes, the tire pressure warning light blinks for 1
minute and stays on 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 sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Maximum load of tire
6
Check that the number given by dividing the maximum load by
1.10 of the
replacement 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. 545)
442
6-3. Do-it-yourself maintenance
■ 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 roads. 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 originally 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 for possible restrictions. Snow tires
should be installed on all wheels. (P. 342)
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■ Warning performance of the tire 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.

■ Situations in which the tire pressure warning system may not oper-
ate properly
● In the following cases, the tire pressure warning system may not operate
properly.
• If non-genuine Toyota wheels are used.
• A tire has been replaced with a tire that is not an OE (Original Equip-
ment) tire.
• A tire has been replaced with a tire that is not of the specified size.
• Tire chains etc. are equipped.
• If a window tint that affects the 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 extremely higher than the specified
level.
• If the spare tire is in a location subject to poor radio wave signal
reception.
• If a large metallic object which can interfere with signal reception is
put near the spare tire.
• If tires not equipped with the tire pressure warning valves and trans-
mitters are used.
• If the ID code on the tire pressure warning valves and transmitters is
not registered in the tire pressure warning computer.
●Performance may be affected in the following situations.
• Near a TV tower, electric power plant, gas station, radio station, large
display, airport or other facility that generates strong radio waves or
6
electrical noise
• When carrying a portable radio, cellular phone, cordless phone or
other wireless communication device
● When the vehicle is parked, the time taken for the warning to start or go
off could be extended.
●When tire inflation pressure declines rapidly for example when a tire has
burst, the warning may not function.

6-3. Do-it-yourself maintenance
■The initialization operation
●Make sure to carry out initialization after adjusting the tire inflation pres-
sure.
Also, make sure the tires are cold before carrying out initialization or tire
inflation pressure adjustment.
●If you have accidentally turned the engine switch to the “LOCK” position
(vehicles without a smart key system) or off (vehicles with a smart key
system) during initialization, it is not necessary to press the reset switch
again as initialization will restart automatically when the engine switch
has been turned to the “ON” position (vehicles without a smart key sys-
tem) or IGNITION ON mode (vehicles with a smart key system) for the
next time.
●If you accidentally press the reset switch when initialization is not neces-
sary, adjust the tire inflation pressure to the specified level when the
tires are cold, and conduct initialization again.
●While the position of each tire is being determined and the inflation pres-
sures are not being displayed on the multi-information display, if the
inflation pressure of a tire drops, the tire pressure warning light will come
on.
■When initialization of the tire pressure warning system has failed
●Do not move the vehicle backward during initialization. Initialization is
started again from the beginning and it may take longer than usual.
● Initialization may take longer to complete if the vehicle is driven on an
unpaved road.
When performing initialization, drive on a paved road if possible.
Depending on the driving environment and condition of the tires, initial-
ization will be completed in approximately 10 to 30 minutes.
• If initialization is not complete after driving approximately 30 minutes,
continue driving for a while.
• If initialization is not complete after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left and right turns) at approximately 25 mph
(40 km/h) or more* for approximately 10 to 30 minutes.
• If initialization is still not complete, have the vehicle inspected by your
Toyota dealer.
*: Except when making a left/right turn
●In the following situations, the tire inflation pressure will not be recorded
and the system will not operate properly. Perform initialization again.
• When operating the tire pressure warning reset switch, the tire pres-
sure warning light does not blink 3 times.
• After performing initialization, the tire pressure warning light blinks for
1 minute then stays on after driving for about 20 minutes.

■ When ID code registration has failed
●Registration may take long time or the ID codes may not be registered in
the following situations.
• When the vehicle is moved backward during registration.
Registration is started again from the beginning and it may take lon-
ger than usual.
• When another vehicle is running the side of the vehicle such as in
heavy traffic.
It may take longer to detect the vehicle’ tire pressure warning valves
and transmitters.
• If tire pressure warning valves and transmitters are in the vehicle.
The ID codes may not be registered.
●When performing registration, drive on a paved road if possible.
Depending on the driving environment and condition of the tires, regis-
tration will be completed in approximately 10 to 30 minutes.
• If registration is not complete after driving approximately 30 minutes,
continue driving for a while.
• If registration is not complete after driving approximately 1 hour, park
the vehicle in a safe place for approximately 20 minutes. Then drive
straight (with occasional left and right turns) at approximately 40 km/h
(25 mph) or more* for approximately 10 to 30 minutes.
If registration is still not complete, have the vehicle inspected by your
Toyota dealer.
: Except when making a left/right turn
●When the tire pressure warning light does not blink slowly 3 times, the
6
ID code will not be registered and the system will not operate properly.
Perform registration again.
■When registering ID codes
●Initialize the tire pressure warning system after ID code registration. Ini-
tialization is disabled if the system was initialized before registration.
●After ID code registration, the tires are hot by driving. Initialize the tire
pressure warning system after the tires become cold.
■Canceling the change wheel set mode
●If turning the engine switch to the “LOCK” position (vehicles without a
smart key system) or off (vehicles with a smart key system) when in the
change wheel set mode before driving, the change wheel set mode is
canceled.
●After driving when in the change wheel set mode, the change wheel set
mode cannot be canceled. To cancel the mode, perform the procedure
for ID code registration again and turn the engine switch to the “LOCK”
position (vehicles without a smart key system) or off (vehicles with a
smart key system) before driving.
●If the change wheel set mode is canceled, the ID codes that have
already been registered are communicated. When communication is fin-
ished, the tire pressure warning light will turn off.

WARNING
■When inspecting or replacing tires
Observe the following precautions to prevent accidents.
Failure to do so may cause damage to parts of the drive train as well as
dangerous handling characteristics, which may lead to an accident
resulting in death or serious injury.
●Do not mix tires of different makes, models or tread patterns.
Also, do not mix tires of remarkably different treadwear.
● Do not use tire sizes other than those recommended by Toyota.
●Do not mix differently constructed tires (radial, bias-belted or bias-ply
tires).
●Do not mix summer, all season and snow tires.
● Do not use tires that have been used on another vehicle.
Do not use tires if you do not know how they were used previously.
■When initializing the tire pressure warning system
Do not operate the tire pressure warning reset switch without first
adjusting the tire inflation pressure to the specified level. Otherwise, the
tire pressure warning light may not come on even if the tire inflation
pressure is low, or it may come on when the tire inflation pressure is
actually normal.
