conditioning system is turned on, cool
dehumidified air will flow through the
vents into the cabin. For improved fuel
economy, press the "A/C" button to
turn off the air conditioning and
manually adjust the blower and
airflow mode settings.
When the "A/C" and "AUTO" are
switched off it is not possible to have
air at a lower temperature than the
outside.
Recirculation and Air Quality
4 Sensor (AQS)
When outside air contains smoke,
odours, or high humidity, or if rapid
cooling is desired, you may wish to
recirculate interior air by pressing the
recirculation control button to activate
the two different functionalities.
The recirculation function, that allows
to open/close the A/C air inlet by
operating the relevant button on the
climate control panel/MTC+ softkey, is
integrated with the Air Quality Sensor.
This sensor, positioned upstream of the
A/C filter, in front of the air intake of
the A/C system, detects the presence of
polluting substances and submits an
electric signal to the A/C control unit,
that closes the intake of the external
air by activating the air recirculation.

The recirculation button/MTC+ softkey
can therefore enable three operating
modes, switchable in sequence.
Starting from the outside air
condition, in which the external air is
aspirated by the A/C system and
treated to be introduced into the
passenger compartment, subsequent
actuations of the button/MTC+ softkey
change the state as follows.
• First press: the A/C system activates
the recirculation, the LED on the
button/MTC+ softkey lights up. The
A/C system will stay this way up to a
new actuation, or until the increased
humidity could lead to windshield
fogging: in this case the recirculation
automatically switches to external
air.
• Second press: the A/C system
activates the automatic recirculation
control by using the signal
transmitted from the AQS. The
symbol ''A'' on the recirculation
button/MTC+ softkey lights up.
• Third press: the A/C system switches
back to external air.
The next press of the recirculation
button/MTC+ softkey restars the
operating cycle just described.
NOTE:
To avoid the risk of fogging, the AQS is
disabled when the external
temperature falls below 2 °C (35 °F).
NOTE:
In cold weather, use of recirculation
mode may lead to window fogging.
Select the MIX mode and increase
the blower speed to prevent fogging.
