Window demisting
Climate control system
√is very use-
ful to speed up window demisting and
it is therefore to be turned on in the
event of considerable moisture. In any
case it is recommended to perform the
following preventive demisting proce-
dure:
❒turn air recirculation off (if on);
❒turn knob Cto second speed;
❒turn knob Bto Q.

DEMISTING/DEFROSTING
Press button (to activate the demist-
ing/defrosting function: when this func-
tion is on, the circular led around the but-
ton will turn on.
On certain versions, turning this function
on will also activate windscreen de-
frosting in the windscreen wiper area.
This function is timed and switches off
automatically after few minutes, or by
pressing again the button or by turning
the engine off. It will not be switched
on automatically when restarting the en-
gine.
IMPORTANTDo not apply stickers on
the inside of the heated rear window
over the heating filaments to avoid dam-
age that might cause it to stop work-
ing properly.
WARMING THE PASSENGER
COMPARTMENT
Proceed as follows:
❒turn knob Ato the required temper-
ature;
❒turn knob Cto the required speed;
❒turn knob Bto the required distribu-

LOOKING AFTER THE
SYSTEM
During the winter, the climate control
system
√must be turned on at least
once a month for about ten minutes.
Before summer, have the system
checked at Alfa Romeo Authorized Ser-
vices.
RECIRCULATION
To turn this function on press button
v: the button led will turn on.
This function is particularly useful when
the outside air is heavily polluted (in a
traffic jam, tunnel, etc.) However, it is
better not to use it for long periods, es-
pecially if there are several people in the
car to prevent window misting up.
Do not use the air recirculation function
on rainy/cold days as it would consid-
erably increase the possibility of the win-
dows misting inside.
IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required (“heating” or “cooling”)
conditions faster.
After connecting/dis-
connecting the battery,
wait for 3 minutes at
least before fitting the electronic
key into the ignition device in
order to allow the climate con-
trol system control unit to reset
the positions of the electric ac-
tuators that adjust air temper-
ature and distribution.

AUTOMATIC TWO-/
THREE-ZONE
CLIMATE CONTROL
SYSTEM
(for versions/markets,
where provided)
DESCRIPTION
The car is fitted with a two-/three-zone
climate control system which makes it
possible to separately adjust the air tem-
perature in the two/three passenger’s
compartment areas to reach the required
comfort.
For top quality temperature control in
the two/three areas of the passenger's
compartment, the system is fitted with
external temperature sensor, passen-
ger's compartment temperature sensor
and two-side sun radiation sensor.
The climate control system automatically
controls and adjusts the following pa-
rameters and functions:
❒air temperature at driver/passengers
vents;
❒fan speed;
❒air distribution at driver/passenger
vents;
❒compressor activation;
❒air recirculation.
The following parameters and functions
can be set or changed manually:
❒required temperature;
❒fan speed;
❒air distribution on seven levels ;
❒compressor on/off;
❒window demisting/defrosting;
❒air recirculation.
The system is fitted with AQS (Air Qual-
ity System) sensor (where provided),
that turns on air recirculation automati-
cally when it detects the presence of out-
side polluted air (for example in queues
and tunnels).
Where provided, the system is integrat-
ed with an anti-misting sensor A-fig. 48
set behind the driving mirror, capable of
“monitoring” a preset internal area of the
windscreen and of intervening automat-
ically to prevent or to reduce window mist-
ing up through a proper strategy.
A0E0091mfig. 48
This sensor can be deactivated through
any manual system control when the
strategy is operating. The sensor is en-
abled at each start-up and in any case
when the user presses one of the AUTO
buttons.
