Alfa Romeo Giulia 2024 Owner's Manual page 57

CAUTION!
The system uses R1234yf refrigerant, which does not
pollute the environment in the event of accidental
leakage. Under no circumstances, use R134a and
R12 fluids, which are incompatible with the
components of this system.
Description
The Automatic Dual Zone Climate Control System
adjusts the temperature and air distribution
independently between the driver and passenger.
The system maintains the set temperature inside the
passenger compartment and compensates for outside
temperature change.
NOTE:
The reference temperature is 72°F (22°C) for optimal
comfort management.
The automatic setting will adjust the following to
maintain comfort within the passenger compartment:
□
Air temperature from the driver/front passenger
side vents
□
Air distribution from the driver/front passenger side
vents
□
Fan speed (continuous variation of the air flow)
□
Compressor variations (for cooling/dehumidifying
the air)
□
Air recirculation
The Climate Control system can also be operated
manually by using the buttons and knobs on the
faceplate.
Manual selections will override the automatic settings,
which are stored until the AUTO button is pushed. If the
system intervenes for safety reasons, the automatic
setting will take control of the system.
The following operations will not deactivate the
automatic (AUTO) function:
□
Air Recirculation activation/deactivation
□
A/C activation/deactivation
□
SYNC function activation
□
Rear Window Defrost activation/deactivation
When in AUTO mode, the vehicle's internal temperature
is controlled according to the set temperature.
The following can be manually set or adjusted:
□
Driver/passenger air temperature
□
Blower speed (continuous variation)
□
Air distribution (seven positions for driver and
passenger)
□
A/C activation
□
Front Defrost
□
Air recirculation
□
Rear Defrost
□
System deactivation
A/C Compressor
Push the A/C button or the icon 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 or 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.
Air Recirculation And Air Quality System (AQS)
Air Recirculation is managed according to
the following operating mode:
□
Automatic engagement: indicator is illuminated
above the "A" on the Air Recirculation Button
□
Forced activation (air circulation always activated):
indicator illuminated above the icon on the Air
Recirculation Button
□
Forced deactivation (air recirculation always off with
intake of outside air): both indicators not illuminated
on the Air Recirculation Button
The three operating conditions are obtained by pushing
the Air Recirculation Button in sequence.
Enabling The Air Quality System (AQS) Function —
If Equipped
When the automatic recirculation function is selected,
the AQS function automatically activates internal air
recirculation when the outside air is polluted (e.g. in
heavy traffic and tunnels).
