√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 BtoQ.

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.

AUTOMATIC TWO-/
THREE-ZONE
CLIMATE CONTROL
SYSTEM
(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;
❒one-zone function.
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 also features
a demisting sensorA-fig. 48 ( set be-
hind the driving mirror), capable of mon-
itoring a preset area of the internal wind-
screen pane and to cut in automatically
to prevent or to reduce misting up through
a suitable strategy.
A0E0091mfig. 48
This sensor can be disabled by any man-
ual control and it is activated each time
the engine is started and in any case
when the user presses one of the AUTO
buttons.

FAN SPEED ADJUSTMENT
Press buttons +/–to increase or to de-
crease the fan speed.
The fan speed is shown by the lit bars on
the display:
❒min fan speed = one bar lit;
❒max fan speed = 6 bars lit;
At starting, if climate control system is
operating in automatic mode, the fan
speed is kept at minimum until the en-
gine has started.
With compressor on and engine running,
the fan speed cannot fall below the min.
speed.
The fan can be cut off (all bars off) on-
ly if the climate control compressor has
been switched off by pressing button
√.
To restore automatic fan speed control
after a manual adjustment, press but-
tons AUTO. AUTO will also go off if the system (spe-
cially when compressor is turned off
manually) cannot reach or cannot keep
the required temperature.
Button
√will not turn off AUTO if the
system can keep the required comfort.
It is inadvisable to use
air recirculation on
rainy/cold days as it would
considerably increase the pos-
sibility of windows misting up
inside.
WARNING
AUTOMATIC OPERATION
(AUTO BUTTON)
Pressing button AUTO (front and rear
controls) the displays will show FULL AU-
TO and the system will automatically ad-
just:
❒fan speed;
❒air distribution in passenger com-
partment;
❒air recirculation;
❒compressor;
and it will cancel all the previous man-
ual adjustments.
Wording FULL will disappear from the
display of the involved area (driver or
front passenger side or rear passenger
side) when performing whatever oper-
ation (excluding temperature change).
