To stop the operation, press .
■Automatic mode indicator
If the fan speed setting or air flow modes are operated, the
indicator goes off. However, automatic mode for functions other
than that operated is maintained.
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.
Front seat concentrated airflow mode operates in the following situa-
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
In front seat concentrated airflow 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, 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

■Heating
●In HV mode, the gasoline engine may operate in order to extract heat from
the engine coolant via the heater.
●In EV mode, heating is done by a heat pump system.
• When the outside temperature is low or it is snowing, compared to con-
ventional vehicles, heating may be less effective and warm air may not
come out.
• If frost has formed on the outside heat exchanger, the heating perfor-
mance will decline. The frost can be removed from the outside heat
exchanger by operating the Remote Air Conditioning System before driv-
ing (P. 535). When frosted over, the heating operation of the Remote
Air Conditioning System starts after defrosting.
• When is turned on, the heating is controlled optimally. Therefore,
the set heating performance may not be achieved even if the fan speed
setting is increased.
●In the following situations the gasoline engine may operate in order to
extract heat from the engine coolant via the heater even in EV mode.
• The outside temperature is approximately 14°F (-10°C) or low
• is operating
■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.
■Water droplets during air conditioning operation• When the outside heat exchanger is
frosted over, fan speed declines and it
may become harder to heat the inte-
rior. However, it is not a malfunction.
In this situation, the air temperature
from the outlets may not change even
though the set temperature is raised.
The outside heat exchanger, accumulator
and air conditioning piping may incur con-
densation or frost may form. During or
after the air conditioning operation, water
droplets may fall from the vehicle. How-
ever, it is not a malfunction.

■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 airflow to all
seats.
■To return to automatic airflow control
With the indicator off, turn the power switch off.

conditioning system, the setting confirma-
tion screen is shown as a pop-up on the
multi-information display.

5206-1. Using the air conditioning system and defogger
PRIUS PRIME_OM_OM47D71U_(U)■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.
■Windshield fog detection function
When automatic mode is set, the humidity sensor (P. 523) detects fog on
the windshield and controls the air conditioning system to prevent fog.
■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.
■Operation of the air conditioning system in the air conditioning eco
mode
●In the air conditioning 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
• Turn off the air conditioning eco mode
●When the driving mode is set to Eco driving mode, the air conditioning eco
mode will be turned on automatically. Even in this case, the air conditioning
eco mode can be turned off by pressing . (P. 430)
■When the outside temperature falls to nearly 32F (0C)
The dehumidification function may not operate even when is pressed.
