Interior features
This function automatically controls the air conditioning airflow so that
priority is given to the front seats. When the front passenger seat is
not occupied, airflow may switch to only the driver’s seat. Unneces-
sary air conditioning is suppressed, contributing to increased fuel effi-
ciency.

tions.
●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

seats only and to all seats can be switched via switch operation.
When the mode has been switched manually, automatic airflow
control stops operating.
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

■Opening and closing the air outlets
■ Using automatic mode
Fan speed is adjusted automatically 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 is pressed.
■ Setting confirmation screen
■ Operation of automatic airflow control
● In order to maintain a comfortable interior, airflow may be directed to seats
without passengers immediately after the hybrid system is started and at
other times depending on the outside temperature.
● After the hybrid system is started, if passengers move around inside or
enter/exit the vehicle, the system cannot accurately detect the presence of
passengers and automatic airflow control will not operate.
■ Operation of manual airflow control
Even if the function is manually switched to directing airflow to only the
front seats, when a rear seat is occupied, it may automatically direct air-
flow to all seats.

■To return to automatic airflow control
With the indicator off, turn the power switch off.
After 60 minutes or more elapse, turn the power switch to ON.
■Front seat concentrated airflow mode (S-FLOW) operation
■Changing settings using the multi-information display
The air conditioning system settings can be changed on the screen
of the multi-information display. (P. 148)
■Fogging up of the windows
●The windows will easily fog up when the humidity in the vehicle is high.
Turning on will dehumidify the air from the outlets and defog the
windshield effectively.
●If you turn 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 vehi-
cle after closing the windows, it is recommended 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 prevent-
ing dirty air from entering the vehicle interior and helping to cool 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.
■Fresh air intake system while parking
When parking, the system automatically switches to outside air mode to
encourage better air circulation throughout the vehicle, helping to reduce
odors that occur when starting the vehicle. When is pressed, the front seat
concentrated airflow mode (S-FLOW) sta-
tus is displayed on the multi-information
display.

PRIUS_OM_OM47F32E_(EE)■Operation of the air conditioning system when the blower customization
is set to “ECO”
●In the “ECO” 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
• Adjust the temperature setting
• Set the blower customization to “FAST” or “NORMAL” mode.
●When the driving mode is set to Eco driving mode, the fan speed setting
mode will be changed to “ECO” mode automatically. Even in this case, the
fan speed control mode can be changed by pressing . (P. 351)
■When the outside temperature falls to nearly 0C (32F)
The dehumidification function may not operate even when is pressed.
■Ventilation and air conditioning odors
●To let the fresh air in, set the air conditioning 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.
●In order to suppress odors that occur when the air conditioning system
starts, fresh air is automatically taken in when parked.
●To reduce potential odors from occurring, 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.
■Air conditioning filter

■Customization
Settings (e.g. outside/recirculated air mode) can be changed.

WARNING
■To prevent the windshield from fogging up
● Do not use during cool air operation in extremely humid weather.
The difference between the temperature of the outside air and that of the
windshield can cause the outer surface of the windshield to fog up, block-
ing your vision.
■ To prevent burns
Do not touch the rear view mirror surfaces when the outside rear view mirror
defoggers are on.
NOTICE
■ To prevent 12-volt battery discharge
Do not leave the air conditioning syst em on longer than necessary when the
hybrid system is off.
■ Air outlets
The air outlets become hot when used for heating. Therefore, use caution
and adjust the air outlets accordingly.
● 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 defogging.
