● Toyota technicians are well-trained specialists and are kept up to date with
the latest service information. They are well informed about th e operations
of all systems on your vehicle.
● Keep a copy of the repair order. It proves that the maintenance that has
been performed is under warranty coverage. If any problem should arise
while your vehicle is under warranty, your Toyota dealer will p romptly take
care of it.

◆Installing tire pressure warning valves and transmitters
When replacing the tires or wheels, the tire pressure warning v alve
and transmitters must be install ed 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. 448)
◆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 ti re
size is changed.
● When rotating the tires.
● Vehicles with a tire inflation pr essure display function: After per-
forming the transmitter ID code registration procedure. ( P. 4 4 8 )
When the tire pressure warning sy stem 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 stop the hybrid system for 20
minutes or more.
The initialization procedure cannot be started while the vehicle is
moving.
Adjust the tire inflation pressure to the specified cold tire i nflation
pressure level. ( P. 550)
Make sure to adjust the tire pre ssure to the specified cold tire infla-
tion pressure level. The tire pressure warning system will oper ate
based on this pr essure level.
Start the hybrid system. ( P. 2 0 6 )
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the ste er-
ing wheel. ( P. 109, 126).
4.2-inch display: Select “Vehi cle Settings” and then press .

◆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 tire pressure warning system se nsor
ID codes initially registered to the vehicle, a second set of ID codes
can be registered.
A second set of tire pressure warning system sensor ID codes ca n
be registered at your Toyota dealer. When 2 sets of ID codes ha ve
been registered, either ID code set can be selected.
Vehicles with a tire inflation pressure display function
Every tire pressure warning valve and transmitter has a unique ID
code. When replacing a tire pressure warning valve and transmit ter,
it is necessary to reg ister the ID codes.
The ID codes can be registered on (4.2-inch display) or (7-
inch display) of the multi-information display.
■Changing the available set of ID codes (vehicles without a tire
inflation pressure display function)
When 2 sets of ID codes are reg istered, the corresponding ID code
set for the installed wheels can be selected on (4.2-inch disp lay)
or (7-inch display) of the multi-information display. It is no t 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 pr es-
sure display function)
Park the vehicle in a safe place, wait for approximately 20 min -
utes, and then start t he hybrid system. (P. 206)
Select (4.2-inch display) or (7-inch display) on the multi-
information display using the meter control switches on the ste er-
ing wheel. ( P. 109, 126)

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 at approximately 25 mph (40 km/h) or more for approxi-
mately 10 to 30 minutes.
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.
Even if the vehicle is not driven at approximately 25 mph (40 k m/h)
or more, registration can be completed by driving for a long ti me.
However, if registration does not complete after driving for 1 hour or
more, perform t he procedure again from the beginning.
Initialize the tire pressure warning system. ( P. 446)

■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 t o
expose the fabric, and bulges indicating internal damage
●A tire goes flat repeatedly or c annot 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 transmit ters 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 indicat e a system
malfunction.
■Tire life
Any tire over 6 years old must be checked by a qualified techni cian even
if it has seldom or never been u sed 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 chec k tire inflation pressure as part of
your routine of daily vehicle checks.
■Low profile tires (vehicl es with 18-inch wheels)
Generally, low profile tires will wear more rapidly and tire gr ip 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 r oads and
drive carefully at a speed approp riate for road and weather conditions.
■Maximum load of tire
Check that the maximum load of t he replacement tire is greater than 1/2
of the Gross Axle Weight Ratings (GAWR) of either the front axl e 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 5 6 )

Maintenance and care
■Tire types
●Summer tires
Summer tires are high-speed performance tires best suited to highway
driving under dry conditions. Si nce summer tires do not have th e 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 sno w and to
be adequate for driving in most winter conditions as well as fo r use
year-round. All season tires, however, do not have adequate tra ction
performance compared with snow tires in heavy or loose snow. Al so, all
season tires fall short in acceleration and handling performanc e com-
pared with summer tires in highway driving.
●Snow tires
For driving on snow-covered roads or icy roads, we recommend us ing
snow tires. If you need snow tires, select tires of the same si ze, con-
struction and load capacity as t he originally installed tires. Since your
vehicle has radial tires as original equipment, make sure your snow
tires also have radial construct ion. Do not install studded tires without
first checking local regulations for possible restrictions. Sno w tires
should be install ed on all wheels. ( P. 360)
■If the tread on snow tires wea rs down below 0.16 in. (4 mm)
The effectiveness of the tires 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 m ay not
operate properly.
• If non-genuine Toyota wheels are used.
• If a tire has been replaced with a tire that is not an OE (Ori ginal
Equipment) tire.
• If a tire has been replaced with a tire that is not of the spe cified size.
• If tire chains, e tc. are installed.
• If a window tint that affects r adio 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 specifi ed level.
• If wheels not equipped with tire pressure warning valve and tr ansmit-
ter are used.
• If the ID codes of the tire pre ssure warning valve and transmi tters 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 statio n, radio
station, large display, airport or other facilit y 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 ti re position
information is not correctly displayed due to the radio wave co nditions,
the display may be corrected by changing the location of the ve hicle 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 exampl e when a
tire has burst, the warning may not operate.
