the soft-key, 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 soft-key can therefore enable
3 operating modes, switchable in
sequence: "Auto", "Manual" and "Open".
Starting from the outside air condition
4
("Open" mode) with soft-key not colored
in amber, 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 soft-key change the state as follows.
• First press - "Auto" mode : the A/C
system activates the automatic
recirculation control by using the signal
transmitted from the AQS. The MIA
soft-key with the symbol "A" in white
illuminates in amber
• Second press - "Manual" mode: the
A/C system activates the recirculation,
the soft-key with the symbol "M"
in white illuminates in amber. 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.
• Third press - "Open" mode: the A/C
system switches back to external air
(default operating mode).
The next press of the soft-key restarts
the operating cycle just described.
NOTE:
To avoid the risk of fogging, the AQS is
disabled when the external temperature
falls below 35 ° F (2 ° C).
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.
MAX A/C
Activating this function, the system
switches to exit automatic mode and
enter A/C and recirculation functions.
The minimum temperature (LO) in both
zones, the maximum blower speed and
the "Dashboard" air distribution mode
are also selected.
The blower speed can be adjusted
without exiting "MAX A/C". To exit "MAX
A/C" touch the relevant MIA soft-key or
exit A/C or recirculation functions.
Selecting , "AUTO", or "OFF", will also
exit "MAX A/C".
Automatic Temperature Control
(ATC)
Automatic operation

the following ways:
• Press the "AUTO" soft-key of driver
and/or passenger zone on the relevant

speeds.
• Set the desired temperature
adjusting the driver and/or passenger
temperature control buttons or soft-
