■Set cooling and dehumidifica-
tion function
Press the “A/C” switch.
When the function is on, the indicator
illuminates on the “A/C” switch.
■Defogging the windshield
Defoggers are used to defog the
windshield and front side windows.
Press the windshield defogger
switch.
Set the outside/recirculated air mode
switch to outside air mode if the recircu-
lated air mode is used. (It may switch
automatically.)
To defog the windshield and the side

Each time the “FAST/ECO” switch
is pressed, the fan speed setting
mode toggles as follows.
Normal  “ECO”  “FAST”  Nor-
mal
When “ECO” is displayed on the air
conditioning screen, the air condi-
tioning is controlled with low fuel
consumption prioritized such as
reducing fan speed, etc.
When “FAST” is displayed on the
screen, fan speed will be
increased.
■Fogging up of the windows
●The windows will easily fog up when
the humidity in the vehicle is high. Turning “A/C” on will dehumidify the air from the outlets and defog the

windshield effectively.
●If you turn “A/C” off, the windows may fog up more easily.
●The windows may fog up if the recir-culated air mode is used.
■When driving on dusty roads
Close all windows. If dust thrown up by the vehicle is still drawn into the vehicle after closing the windows, it is recom-
mended that the air intake mode be set to outside air mode and the fan speed to any setting except off.
■Outside/recirculated air mode
●Setting to the recirculated air mode temporarily is recommended in pre-
venting dirty air from entering the vehicle interior and helping to cool the vehicle when the outside air tempera-
ture is high.
●Outside/recirculated air mode may
automatically switch depending on the temperature setting or the inside tem-perature.
■Operation of the air conditioning
system in Eco drive mode
●In Eco drive mode, the air conditioning
system is controlled as follows to pri- oritize fuel efficiency:• Engine speed and compressor opera-
tion controlled to restrict heating/cool- ing capacity• Fan speed restricted when automatic
mode is selected
●To improve air conditioning perfor-
mance, perform the following opera- tions:• Adjust the fan speed
• Turn off Eco drive mode ( P.275)
●Even when the drive mode is set to
Eco drive mode, the air conditioning eco mode can be turned off by press-ing the “FAST/ECO” switch. ( P.290)
■When the outside temperature falls
to nearly 0°C (32°F)
The dehumidification function may not operate even when “A/C” switch is
pressed.
■Ventilation and air conditioning
odors
●To let fresh air in, set the air condition-
ing system to the outside air mode.
●During use, various odors from inside
and outside the vehicle may enter into and accumulate in the air conditioning system. This may then cause odor to
be emitted from the vents.
●To reduce potential odors from occur-
ring: • It is recommended that the air condi-tioning system be set to outside air
mode prior to turning the vehicle off. • The start timing of the blower may be delayed for a short period of time
immediately after the air conditioning system is started in automatic mode.
●When parking, the system automati-cally switches to outside air mode to encourage better air circulation
throughout the vehicle, helping to reduce odors that occur when starting the vehicle.

■Customization
Some functions can be customized. ( P.431)
WARNING
■To prevent the windshield from fogging up
Do not use the windshield defogger
switch during cool air operation in extremely humid weather. The differ-ence between the temperature of the
outside air and that of the windshield can cause the outer surface of the windshield to fog up, blocking your
vision.
■When the outside rear view mir-
ror defoggers are operating
Do not touch the outside rear view mirror surfaces, as they can become
very hot and burn you.

8 Drive straight (with occasional
left and right turns) at approxi-
mately 40 km/h (25 mph) or
more for approximately 10 to 30
minutes.
Even if the vehicle is not driven at approximately 40 km/h (25 mph) or more, initialization can be completed by
driving for a long time. However, if ini- tialization does not complete after driv-ing for 1 hour or more, park the vehicle
in a safe place for more than 15 min-
utes and please drive a vehicle once
again with the power switch ON. ( P.340)
■Initialization procedure
●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 power switch off during initialization, it is not necessary to press the reset
switch again as initialization will restart automatically when the power switch is turned to ON 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 infla-
tion pressure of a tire drops, the tire pressure warning light will come on.
■If the tire pressure warning system is not initialized properly
●In the following situations, initialization
may take longer than usual to be com- pleted or may not be possible. (Usu-ally, the vehicle will need to be driven
for approximately 10 to 30 minutes to complete initialization.) If initialization is not complete after driving approxi-
mately 30 minutes, continue driving for a while.• If the vehicle is driven on an unpaved
road, it may take longer to complete initialization.• If the vehicle is backed up while per-
forming initialization, data collected during initialization will be cleared and it will take longer than normal to com-
plete. • If the vehicle is driven in heavy traffic or another situation where other vehi-

cles are driven close by, it may take
time for the system to recognize the tire pressure warning valve and trans-mitters of your vehicle over those of
other vehicles.
If initialization is not complete after driv-
ing 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 com- pleted properly and the system will not operate properly. Perform the initial-
ization procedure again. • If, when attempting to start initializa-tion, the tire pressure warning light
does not blink 3 times. • If, when the vehicle has been driven for about 20 minutes after performing
initialization, the tire pressure warning light blinks for approximately 1 minute and then illuminates.
●If initialization cannot be completed after performing the above procedure,
contact any authorized Toyota retailer or Toyota authorized repairer, or any reliable repairer.
The tire pressure warning valve
and transmitter is equipped with a
unique ID code. When replacing a
tire pressure warning valve and
transmitter, it is necessary to regis-
ter the ID code.
The ID codes can be registered on
of the multi-information display.
Park the vehicle in a safe place,
wait for approximately 15 minutes
or more and perform the procedure.

WARNING
■When initializing the tire pres- sure warning system
Do not initialize the tire pressure
warning system without first adjusting the tire inflation pressure to the speci-fied 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.
