AIR TEMPERATURE
ADJUSTMENT KNOBS
Turning the knob knurled rings (B/
E/P), clockwise or counter-clockwise,
respectively raises or lowers the tem-
perature of the air required respective-
ly in the left front zone (knob B) or right
front zone (knob E) or rear zone (knob
P) of the passenger compartment. The
temperatures set are shown on the dis-
play D/S.
Turning the knob knurled rings fully
clockwise or counter-clockwise until they
reach the extreme selections HI or LO,
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 passengers’ side, or
both of them; this setting brings the sys-
tem 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 (excluding
(, 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
passengers).

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.
It is inadvisable to use
air recirculation on
rainy/cold days as it would
considerably increase the pos-
sibility of windows misting up
inside.

AIR RECIRCULATION AND
AQS FUNCTION (AIR
QUALITY SYSTEM)
ON/OFF
(for versions/markets,
where provided)
Inside air recirculation is controlled ac-
cording to the following operating log-
ics:
❒automatic control, indicated by but-
ton led “A”;
❒forced switching on (inside air recir-
culation always on), indicated by the
turning on of the circular led around
the button;
❒forced switching off (air recirculation
always off with air inlet from the out-
side), indicated by the turning off of
the circular led around the button.
With A.Q.S. (air quality sensor - where
provided), the operating logics becomes
sequential by pressing button
v.IMPORTANTThe inside air recircula-
tion system makes it possible to reach
the required heating or cooling condi-
tions faster. It is however inadvisable to
use it on rainy/cold days as it would
considerably increase the possibility of
the windows misting inside, especially
if the climate control compressor is off.
It is advisable to turn on the inside air
recirculation system in queues or tunnels
to avoid admitting polluted air from out-
side. The prolonged use of this function
should however be avoided, especially
with several persons on board, to avoid
the possibility of the windows misting
inside and to guarantee the required
fresh air inlet.
In certain weather con-
ditions (e.g. outside
temperature around
0°C) and with automatic air re-
circulation control on, mist may
form on the windows. In this
case press button
vto
switch off recirculation and if
necessary press button + to in-
crease the flow of air to the
windscreen.
With the outside tem-
perature below -1°C the
climate control compres-
sor is unable to work. It is
therefore inadvisable to use the
inside air recirculation function
with low outside temperature
as windows may mist over
quickly.

POLLEN FILTER/ ACTIVATED
CARBON POLLEN FILTER
According to versions, the car can be fit-
ted with pollen filter or activated carbon
pollen filter (where provided). The filter
has the specific capability of admitting to
the passenger compartment purified air,
free from particles such as dust, pollen,
etc. The filtering action takes place un-
der all air inlet conditions and it is clear-
ly most effective with the windows shut.
Have the conditions of the filter checked
by Alfa Romeo Authorized Services at
least once a year, preferably at the on-
set of summer.
If the car is used mainly in polluted or
dusty areas it should be checked and if
necessary replaced at shorter intervals
than specified in the Service Schedule
(see section “Car Maintenance”). AQS function (Air Quality
System) (for versions/markets,
where provided)
The AQS function turns on automatical-
ly air recirculation when it detects the
presence of polluted air (e.g. in queues
and tunnels).
IMPORTANTWith AQS function on,
after a preset time with recirculation on,
the compressor will enable outside air
inlet (for about 1 minute) to change air
inside the passenger compartment, re-
gardless of outside air pollution level.
IMPORTANTThe AQS function is dis-
abled when the outside temperature is
cold to prevent window misting up. To
reactivate this function, press button
v. Led “A” on button vwill
turn on to indicate that the function is
on.
Failure to replace the fil-
ter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the
outlets and vents.
