3 - air distribution knob:
Air flow to the windscreen and front side window diffusers to demist/defrost them.
Air flow to the front and rear footwell diffusers. This air distribution allows the passenger compartment to be warmed up quickly.
Air flow distribution between front and rear diffusers, centre/side dashboard diffusers, rear diffuser and windscreen and front
side window demisting/defrosting diffusers.
Air flow to central/side dashboard diffusers (passenger’s body).
4 - air recirculation on/off button
5 - heated rear window on/off button;
6 - climate control compressor on/off button;
IMPORTANT In warm-humid weather conditions, using cold air on the windscreen may cause external condensation.

7 - passenger's side temperature adjustment knob;
8 - MONO function button (set temperature alignment) driver/passenger side;
9 - air distribution selection buttons;
10 - fan speed knob;
11 - climate control system on/off button;
12 - internal air recirculation on/off button;
Air distribution selection
Air flow to the windscreen and front side window vents to demist/defrost them.
Air flow at central and side dashboard vents to ventilate the chest and the face during the hot season.
Air flow to the front and rear footwell vents. This air distribution setting heats the passenger compartment most quickly, giving
a prompt sensation of warmth
IMPORTANT In warm-humid weather conditions, using cold air on the windscreen may cause external condensation.
In AUTO mode, the climate control system automatically manages air distribution (the LEDs on buttons H are off). When set
manually, the air distribution is indicated by the LEDs on the selected buttons switching on.
You can also set a combination of the air distribution settings described above. In combined function mode the relevant function is
enabled simultaneously with those already set by pressing the corresponding button. If a button whose function is already active is
pressed, the operation is cancelled and the corresponding LED switches off. To restore automatic control of the air distribution after
a manual selection, press the AUTO button.
Start&Stop
The automatic dual zone climate control system manages the Start&Stop system (engine off when car speed is 0 km/h) to ensure
adequate comfort inside the car. When the Start&Stop system is on (engine off and car at a standstill), the automatic recirculation
management is turned off always taking air in from outside, to reduce the probability of the windows misting up (as the compressor
is off).
IMPORTANT
2)The system uses a coolant that is compatible with the laws in force in the countries where the vehicle is sold, R134a or R1234yf (indicated on a
specific plate in the engine compartment). The use of other coolants affects the efficiency and condition of the system. Also the compressor
coolants used must be compatible with the indicated coolant.

KNOWING THE INSTRUMENT PANEL

MISSED ENGINE STOPPING
CONDITIONS
When the system is active, for a higher
comfort and safety, and to reduce
emissions, the engine does not stop in
certain ambient conditions, engine
conditions, with the doors not closed and
seat belts unfastened.
30)
ENGINE RESTARTING CONDITIONS
Due to comfort, emission control and
safety reasons, the engine can restart
automatically without any action by the
driver, when the vehicle and the climate
control system are in certain conditions,
such as:
With gear engaged, automatic engine
restarting is possible only by fully
pressing the clutch pedal. The driver is
informed by the displaying of a message
on the display and - for versions/markets,
where provided - by the flashing of the
symbol
.
SAFETY FUNCTIONS
When the engine is stopped by the
Start&Stop system, if the driver releases
his/her seat belt and opens the driver's or
passenger's door, the engine can be
restarted only by the ignition key.
The driver is informed by a buzzer and by
the flashing of the symbol
on the
display (on some versions, a message is
displayed as well).
"ENERGY SAVING" FUNCTION(for versions/markets, where provided)
If, following the automatic engine
restarting, the driver does not carry out
any action on the vehicle for over
3 minutes, the Start&Stop system stops
the engine definitely, to prevent fuel
consumption. In these cases, the engine
can be restarted only using the ignition
key.
NOTE In any case, it is possible to keep
the engine running by deactivating the
Start&Stop system.
IRREGULAR OPERATION
In the event of malfunction, the
Stop/Start system is deactivated.
The driver is informed of the fault by the
flashing of the symbol
.For
versions/markets, where provided, a
warning message will also appear on the
display.
In this case, contact an Alfa Romeo
Dealership.
VEHICLE INACTIVITY
In the event of vehicle inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection of the
battery power supply.
98)
IMPORTANT
30)If climate comfort is to be favoured, the
Stop/Start system can be deactivated, for a
continuous operation of the climate control
system.
WARNING
98)When replacing the battery, always
contact an Alfa Romeo Dealership. Replace
the battery with one of the same type
(HEAVY DUTY) and with the same
specifications.
