3065-3. Using the air conditioning system and defogger
If the fan speed setting or air flow modes
are operated, the automatic mode indica-
tor goes off. However, automatic mode for
functions other than that operated is main-
tained.
■Using automatic mode
Fan speed is adjusted automatically accord-
ing 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 immedi-
ately after the automatic mode switch is
pressed or “AUTO” is selected.
Cool air may blow ar ound the upper body
even when the heater is on due to sunlight.
■Automatic mode for air intake control (if
equipped)
In automatic mode, the system detects
exhaust gas and other pollutants and auto-
matically switches between outside air and
recirculated air modes.
When the dehumidificati on function is off,
and the fan is operating, turning automatic
mode on will activate the dehumidification
function.
This function automatically controls the
air conditioning airflo w 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.
■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.
