Alfa Romeo Giulia Quadrifoglio 2017 Owner's Manual page 49

The engagement of the recirculation
system makes it possible to reach the
required heating or cooling conditions
faster. It is, however, inadvisable to use
it on rainy/cold days as it can increase
the possibility of the windows fogging.
When the outside temperature is low,
recirculation is forced off to prevent the
windows from fogging up.
A/C Compressor
Push the A/C button to activate or
deactivate the A/C compressor
(indicator illuminated when activated).
The A/C compressor will remain off
even after the engine has stopped.
When the A/C compressor is turned off,
the system deactivates air recirculation
to prevent the windows from fogging
up. If the climate control system can
maintain the temperature, with the A/C
turned off, the AUTO feature will remain
on and the AUTO button indicator light
will not switch off.
To restore automatic control of the A/C
compressor, push the A/C button
the AUTO button. With the A/C
compressor off, the air speed can be
set manually using the Air Speed
Adjustment Knob.
When the A/C compressor is on, and
the engine is running, air speed cannot
be lower than the minimum speed (only
one indicator light is lit).
Note: When the A/C is off the Climate
Control system can not produce air that
is colder than the current outside
temperature. Under certain
environmental conditions, windows
could fog up rapidly, since the air is not
dehumidified.
Front Defroster And
MAX-DEF Function
Push the Front Defroster button
(indicator illuminated) to defrost the
windshield and side windows.
While in MAX-DEF function, the air
conditioner will:
Activate the air conditioner
compressor when the weather allows
Turn air recirculation off
Set the maximum air temperature (HI)
on both the driver and passenger side
Activate a blower speed based on
the temperature of the engine coolant
Adjust the air flow towards the
windshield and front side windows
Activate the Rear Window Defroster
Display the fan speed (indicators
illuminated) and current air distribution
or
setting
Note: The MAX-DEF function remains
active for approximately three minutes
once the engine coolant reaches the
proper temperature.
When the function is on, AUTO mode
will deactivate. The only manual
operations possible are adjusting
blower speed and turning off the Rear
Window Defroster.
Pushing the button switches off the
MAX-DEF function.
Rear Defroster
Push the Rear Defroster button to
activate (indicators illuminated) the Rear
Defroster.
The Rear Defroster will turn off after
20 minutes or once the engine is turned
off. To reactive the Rear Defroster, push
the Rear Defroster button.
Note: To avoid damage, do not apply
stickers over the interior heating
filaments of the Rear Defroster.
Humidity Sensor
The Humidity Sensor helps to prevent
the windows from fogging up. The
AUTO function (indicator illuminated)
must be on for the Humidity Sensor to
function.
When outside temperature is low, the
system may turn the compressor on
and turn air recirculation off for safer
driving.
