5-3. Using the air conditioning system
Interior features
controls the air conditioning system to pre-
vent fog.
Q Automatic mode for air intake control
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidification function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function. The next time the dehumidification
function is turned off, automatic mode for
switching between outside air and recircu-
lated air modes is canceled.
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. Unnecessary air conditioning is
suppressed, contributing to increased
fuel 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.
Q Manually turning front seat con-
centrated 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 operat-
ing.
Select on the center display
and switch the airflow.
 Indicator illuminated: Airflow to the
front seats only
 Indicator off: Airflow to all the seats
Q Operation of automatic airflow control
O In order to maintain a comfortable inte-
rior, airflow may be directed to seats
without passengers immediately after the
hybrid system is started and at other
times depending on the outside tempera-
ture.
O After the hybrid system is started, if pas-
sengers move around inside or enter/exit
the vehicle, the system cannot accurately
detect the presence of passengers and
automatic airflow control will not oper-
