■Using the automatic mode
Fan speed is adjusted automatically in accordance with the temperature set-
ting and ambient conditions. As a result, the following may occur.
●Immediately after
is pressed, the fan may stop for a while until
warm or cool air is ready to flow.
● Cool air may flow to the area around the upper body when the heater is
on.
■ Switching between outside air and recirculated air modes
Recirculated air mode or outside air mode may be automatically switched in
accordance with under these condition, such as temperature setting and
inside temperature.
Also, outside air mode may be automatically switched to when the outside
temperature is low.
■ When the outside temperature exceeds 75
F (24C) and the air condi-
tioning system is on
● In order to reduce the air conditioning power consumption, the air condi-
tioning system may switch to recirculated air mode automatically. This
may also reduce fuel consumption.
● Recirculated air mode is selected as a default mode when the “POWER”
switch is turned to ON mode.
● It is possible to switch to outside air mode at any time by pressing
.
■ Using the system in recirculated air mode
The windows will fog up more easily if the recirculated air mode is used.
■ Window defogger feature
●Recirculated air mode may automatically switch to outside air mode in
situations where the windows need to be defogged.
● When the outside air temperature is low, it may take a while for the con-
densation to clear from the windshield.

Interior features
■If air flow from the vents decreases dramatically
The filter may be clogged. Contact your Toyota dealer.
■ Operation of the air conditio ning system in Eco drive mode
In the Eco drive mode, the air conditioning system is controlled as follows to
prioritize fuel efficiency:
● Engine speed and compressor operation controlled to restrict heating/
cooling capacity
● Fan speed restricted when automatic mode is selected
To improve air conditioning performance, perform the following operations:
● Adjust the fan speed
● Turn off Eco drive mode ( P. 206)
● Customize the air conditioning control of Eco drive mode. ( P. 596)
■ When outside air temperature is below 32 °F (0 °C)
The cooling and dehumidification function may not operate even when
is pressed.
■ Air conditioning odors
●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 occurring:
• It is recommended that the air conditioning 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.
■ Customization
Settings (e.g. enable/disable automatic operation of the air conditioning
compressor when the “AUTO” switch ON) can be changed.

If the interior lights remain on when the door is not fully closed and the inte-
rior light switch (door position on/off) is on, the lights will go off automatically
after 20 minutes.
■ Customization
Setting (e.g. The time elapsed before lights turn off) can be changed.

Maintenance and care
■Initializing the tire pressure warning system
Initialize the system with the tire infl
ation pressure adjusted to the speci-
fied level.
■If the tread on snow tires wears down below 0.16 in. (4 mm)
The effectiveness of the tires as snow tires is lost.
■If you press the tire pressure warning reset switch accidentally
If initialization is performed, adjust t he tire inflation pressure to the speci-
fied level and initialize the tire pressure warning system again.
■When initialization of the tire pressure warning system has failed
Initialization can be completed in a few minutes. However, in the follow-
ing cases, the settings have not been recorded and the system will not
operate properly. If repeated attempts to record tire inflation pressure
settings are unsuccessful, have the vehicle inspected by your Toyota
dealer.
●When operating the tire pressure warning reset switch, the tire pres-
sure warning light doe s not blink 3 times.
●After carrying out the initialization procedure, the tire pressure warn-
ing light blinks for 1 minute then stays on after driving for 20 minutes.
