(fast cooling)
IMPORTANTThe compressor √can
be enabled only if the ventilation is en-
abled.
Proceed as follows:
❒turn knob Acompletely leftwards;
❒turn knob Cto top speed;
❒turn knob BtoO;
❒press buttons √andv(buttons
leds on).
How to keep the required
cooling
Proceed as follows:
❒turn air recirculation off (if on).
❒turn knob Ato the required tem-
perature;
❒turn the knurled ring Cto the re-
quired fan speed.
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/discon-
necting the battery,
wait for 3 minutes at
least before fitting the elec-
tronic key into the ignition de-
vice in order to allow the cli-
mate control system control unit
to reset the positions of the
electric actuators that adjust air
temperature and distribution.

AUTOMATIC
TWO-ZONE CLIMATE
CONTROL SYSTEM
(for versions/markets,
where provided)
DESCRIPTION
The car is fitted with a two-zone climate
control system which makes it possible
to separately adjust the air temperature
in the two passenger’s compartment ar-
eas to reach the required comfort.
To obtain top control of both zones, the
system is fitted with outside temperature
sensor, passenger’s compartment tem-
perature sensor and bilateral sun radia-
tion 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. 42
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. This
sensor can be deactivated through any
manual system control when the strate-
gy is operating. The sensor is enabled at
each start-up and in any case when the
user presses one of the AUTO buttons.

AIR TEMPERATURE
ADJUSTMENT KNOBS
Turning the knob knurled rings (B/E),
clockwise or counter-clockwise, respec-
tively highers or lowers the temperature
of the air required respectively in the left
zone (knob B) or right zone (knob E)
of the passenger compartment. The tem-
peratures set are shown on the display
D.
Turning the knob knurled rings fully
clockwise or counter-clockwise until they
reach the extreme selections HIorLO,
the maximum heating or cooling func-
tions are respectively engaged.HI function (HIGH)
(maximum heating power)
It is switched on by setting a tempera-
ture of more than 32°C on the display,
and can be switched on independently
from the driver’s or passenger’s side,
or both of them; this setting brings the
system to the “one-zone” mode and it
is shown by both displays.
This functions can be switched on when
you wish to heat the passenger com-
partment as quickly as possible, by tak-
ing the greatest advantage from the sys-
tem potential.
The function uses the maximum tem-
perature of the heating fluid, whereas
air distribution and fan speed are con-
trolled automatically by the system.
SWITCHING THE CLIMATE
CONTROL SYSTEM ON
The system can be turned on by press-
ing any button (except
(,vand
OFF); it is however advisable to set the
required temperatures on the display
and then to press the AUTO button.
The climate control system allows to per-
sonalise required temperatures (driver and
passenger).

LO function (LOW)
(highest cooling power)
It is switched on by setting a tempera-
ture lower than 16°C on the display;
this setting is shown on the display. This
function can be switched on when you
wish to cool the passenger compartment
as quickly as possible, by taking the
greatest advantage from the system po-
tential.
The function cuts off air heating, switch-
es on both internal air recirculation (to
prevent hot air from entering the com-
partment) and the climate control com-
pressor, brings air distribution to
¯/˙
and the fan speed is controlled auto-
matically by the system. With the function switched on, howev-
er, all the manual settings can be made.
To switch the function off, you only need
to turn the ring of knob B/Eof the tem-
perature set to a value greater than
16°C; the opposite display will show
16°C.
Pressing button AUTO, the display will
show a temperature of 16°C and re-
turns to an operating condition with au-
tomatic temperature adjustment. This function should not be ac-
tivated when the engine is cold,
to prevent air not warm enough
from entering the passenger
compartment.
With the function switched on, howev-
er, all the manual settings can be made.
To switch the function off, you only need
to turn the ring of knob (BorE) of the
temperature set to a value lower than
32°C; the opposite display will show
32°C.
Pressing button AUTO, the display will
show a temperature of 32°C and re-
turns to an operating condition with au-
tomatic temperature adjustment.
