heated air.
■Setting the fan speed
Operate the fan speed control
switch upwards to increase the
fan speed and downwards to
decrease the fan speed.
Press the “OFF” switch to turn off
the fan.
■Change the airflow mode
Operate the airflow mode con-
trol switch upwards or down-
wards.
The mode changes as follows each
time the switch is operated.
1 Air flows to the upper body.
2 Air flows to the upper body

■Switching between outside
air and recirculated air
modes
Press the outside/recirculated
air mode switch.
The mode switches between out-
side air mode (the indicator is off)
and recirculated air mode (the indi-
cator is on) each time the switch is
pressed.
■Set cooling and dehumidifi-
cation function
Press the “A/C” switch.
When the function is on, the indica-
tor illuminates on the “A/C” switch.
■Defogging the windshield
Defoggers are used to defog the
windshield and front side win-
dows.
Press the windshield defogger
switch.
Set the outside/recirculated air
mode switch to outside air mode
if the recirculated air mode is
used. (It may switch automati-
cally.)
To defog the windshield and the
side windows quickly, turn the
air flow and temperature up.

When the windshield defogger
switch is on, the indicator illumi-
nates on the windshield defog-
ger switch.
■Defogging the rear window
and outside rear view mir-
rors
Defoggers are used to defog the
rear window and to remove rain-
drops, dew and frost from the
outside rear view mirrors.
Press the rear window and out-
side rear view mirror defogger
switch.
The defoggers will automati-
cally turn off after a period of
time.
■Windshield wiper de-icer (if
equipped)
This feature is used to prevent
ice from building up on the wind-
shield and wiper blades.
Press the windshield wiper de-
icer switch.
The indicator comes on when
the windshield wiper de-icer is
on.
The windshield wiper de-icer will
automatically turn off after a
period of time.
■Fogging up of the windows
●The windows will easily fog up
when the humidity in the vehicle is
high. Turning “A/C” switch on will
dehumidify the air from the outlets
and defog the windshield effec-
tively.
●If you turn “A/C” switch off, the
windows may fog up more easily.
●The windows may fog up if the
recirculated 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 recommended that the air intake
mode be set to outside air mode and
the fan speed to a ny setting except
off.
■Outside/recirculated air mode
●Setting to the recirculated air
mode temporarily is recom-
mended in preventing dirty air
from entering the vehicle interior
and helping to c ool the vehicle
when the outside air temperature
is high.
●Outside/recirculated air mode may
automatically switch depending on
the temperature setting or the
inside temperature.
■When the outside temperature
exceeds 75°F (24°C) and the air
conditioning system is on
●In order to reduce the air condi-
tioning power consumption, the air
conditioning system may switch to

Interior features
recirculated air mode automati-
cally. This may also reduce elec-
tricity consumption.
●Recirculated air mode is selected
as a default mode when the power
switch is turned to ON.
●It is possible to switch to outside
air mode at any time by pressing
the outside/recirculated air mode
switch.
■When the outside temperature
falls to nearly 32°F (0°C)
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 condi-
tioning system to the outside air
mode.
●During use, various odors from
inside and outside the vehicle may
enter into and a ccumulate 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 out-
side 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 con-
ditioning system is started in auto-
matic mode.
●When parking, the system auto-
matically switches to outside air
mode to encourage better air cir-
culation throughout the vehicle,
helping to reduce odors that occur
when starting the vehicle.

for functions other than that
operated is maintained.
■Using automatic mode
Fan speed is adjusted automati-
cally according to the temperature
setting and the ambient conditions.
Therefore, the fan may stop for a
while until warm or cool air is ready
to flow immediately after the auto-
matic mode switch is pressed.
To turn on the “SYNC” mode,
perform any of the following pro-
cedures:
 Press the “SYNC” mode
switch.
 Adjust the front passenger’s

The indicator comes on when the
“SYNC” mode is on.
WARNING
■To prevent the windshield
from fogging up
Do not use the windshield defog-
ger switch during cool air opera-
tion in extremely humid weather.
The difference between the tem-
perature of the outside air and
that of the windshield can cause
the outer surface of the wind-
shield to fog up, blocking your
vision.
■To prevent burns
●Do not touch the rear view mir-
ror surfaces when the outside
rear view mirror defoggers are
on.
●Vehicles with windshield wiper
de-icer: Do not touch the glass
at lower part of the windshield
or to the side of the front pillars
when the windshield wiper de-
icer is on.
NOTICE
■To prevent 12-volt battery dis-
charge
Do not leave the air conditioning
system on longer than necessary
when the EV system is off.
■When repairing/replacing
parts of the air conditioning
system
Have repair/replacement per-
formed by your Toyota dealer.
When a part of the air conditioning
system, such as the evaporator, is
to be replaced, it must be
replaced with a new one.

This function automatically con-
trols the air conditioning airflow
so that priority is given to the
front seats. Unnecessary air
conditioning is suppressed, con-
tributing to increased electricity
consumption efficiency.
Front seat concentrated airflow
mode operates in the following
situations.
No passengers are detected
in the rear seats
 The windshield defogger is
not operating
While operating, illuminates.
■Manually turning front seat
concentrated airflow mode
on/off
In front seat concentrated air-
flow mode, directing airflow to
the front seats only and to all
seats can be switched via switch
operation. When the mode has
been switched manually, auto-
matic airflow control stops oper-
ating.
Press on the air conditioning
operation panel and switch the
airflow.
 Indicator illuminated: Airflow
to the front seats only
 Indicator off: Airflow to all the
seats
■Operation of automatic airflow
control
●In order to maintain a comfortable
interior, airflow may be directed to
seats without passengers immedi-
ately after the EV system is
started and at other times depend-
ing on the outside temperature.
●After the EV system is started, if
passengers move around inside
or enter/exit the vehicle, the sys-
tem cannot accura tely detect the
presence of passengers and auto-
matic airflow control will not oper-
ate.
■Operation of manual airflow
control
Even if the function is manually
switched to directing airflow to only
the front seats, w hen a rear seat is
occupied, it may automatically direct
airflow to all seats.
WARNING
■To not interrupt the wind-
shield defogger from operat-
ing
Do not place anything on the
instrument panel which may cover
the air outlets. Otherwise, air flow
may be obstructed, preventing the
windshield defoggers from defog-
ging.
