4166-3. Do-it-yourself maintenance
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 the tire pressure drops below
a predetermined level, the
driver is warned by a screen
display and a warning light.

Maintenance and care
◆Installing tire pressure warning valves 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. 419)
◆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. 419)
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. 508)
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.
Start the hybrid system. (P. 1 9 6 )
Select on the multi-information display using the meter con-
trol switches on the steering wheel. (P. 1 1 1 )

performed.
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.
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. 423)

Maintenance and care
◆Registering ID codes
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.
■How to register the ID codes
Select on the multi-information display using the meter con-
trol switches on the steering wheel. (P. 1 1 1 )
Select and then press and hold .
Select “TPWS” and then press .
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 each 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. 424)
After registering the ID codes, make sure to initialize the tire pres-
sure warning system. (P. 417)

■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 pressure warning system will not work properly. In this
case, after driving for about 20 minutes, 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 sure to check tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (vehicles with 18 or 19-inch wheels)
Generally, low profile tires will wear more 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 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. 5 1 3 )

4226-3. 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 much 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, radio
station, 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
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.
■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 initialization 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.
●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.

Maintenance and care
■Tire pressure warning system certification
FCC ID: PAXPMVE000
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 initialize the tire pressure warning system without first adjusting
the tire inflation pressure to the specified level. Otherwise, the tire pres-
sure 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 nor-
mal.
