Air quality control is also entrusted to a
combined particle and activated carbon fil-
ter. The climate control system automatically
controls and adjusts the following parame-
ters and functions:
– temperature of the air admitted to the
passenger compartment (for the driver’s and
passenger’s side separately)
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
It is possible to change the setting of the
following functions manually:
– fan speed
– air distribution
– inside air re-circulation on/off
– climate control compressor on/off en-
able.
The control of functions not changed man-
ually remains automatic and in any case the
temperature of the air admitted to the pas-
senger compartment is controlled automati-
cally according to the temperatures set on
the driver’s and passenger’s displays.
IMPORTANTManual selections prevail
over automatic ones and remain in storage
until the user decides to resume automatic
control. The settings selected manually are
stored when the engine is switched off and
resumed the next time it is started. To ensure correct opera-
tion of the incipient mist-
ing sensor, stickers must
not be applied (road licence holder,
time card etc.) in the “control”
area between the sensor and the
windscreen. Care should also be
given to cleaning the windscreen
and the actual sensor, avoiding the
accumulation of dust and other sub-
stances.IMPORTANTThe demisting procedure
is enabled each time the ignition key is
turned to MARor pressing the
AUTObut-
ton. When this procedure is working it can
be turned off pressing one of the following
buttons: compressor, air re-circulation, air
flow, air capacity. This operation inhibits the
incipient misting sensor signal until the
AU-
TObutton is pressed again or the next time
the ignition key is turned to MAR.
On certain versions, the system is inte-
grated by an antipollution sensor capable of
automatically switching on inside air re-cir-
culation to lessen the harmful effects of pol-
luted air in cities, queues, tunnels and op-
eration of the windscreen washer (with the
typical smell of spirits).
IMPORTANTThe function of the an-
tipollution sensor is subordinate to safety
conditions; therefore disabling the climate
control compressor or at an outside tem-
perature below 4°C the sensor is disabled.
The sensor can be re-enabled pressing the
re-circulation button
vuntil taking it to
the automatic mode. On some versions the system is integrat-
ed with an incipient misting sensor installed
behind the inside rear-view mirror, capable
of “controlling” a predefined area of the
windscreen inner surface which can auto-
matically act on the system to prevent or re-
duce misting through a series of operations
such as: opening air re-circulation, enabling
the compressor, air flow to the windscreen,
fan speed sufficient for demisting; in the
case of heavy misting, enabling the
MAX-
DEFfunction.

HI function
(highest heating power - fig. 79)
This is turned on setting on the display a
temperature above 32.5°C, and can be ac-
tivated independently from the driver’s or
passenger’s side or both; this setting brings
the system to the “monozone” mode and
is shown on both displays.
This function can be engaged when re-
quiring to heat the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
This function uses the maximum temper-
ature of the coolant fluid, while air distribu-
tion and fan speed are controlled according
to the system settings.
This function is unadvisable with
the engine cold to prevent admit-
ting air that is not warm enough to
the passenger compartment.
All manual settings are possible with this
function on.
To switch the system off, simply turn the
ring of knob (2) or (6) of the temperature
set to a value below 32.5°C; the opposite
display will show 32.5°C.

off to prevent misting the windows; even
if unadvisable, it is still possible to restore
automatic operation of inside air re-circula-
tion pressing button (8)
v.
With the climate control compressor off, it
is not possible to admit air to the passenger
compartment with a temperature below
the outside temperature; in this case, the
value flashes on the display concerning the
temperature that cannot be reached and the
left led on button (13

Pressing button (7)
-the climate con-
trol automatically activates timed operation
of all the functions needed to quicken
demisting/defrosting of the windscreen and
front side windows, i.e.:
- it turns on the climate control compres-
sor;
- switches off inside air re-circulation, if on
(both leds off);
- sets the maximum air temperature (HI)
on both displays (1) and (5);
- operates the fan at a predefined speed;
- directs the flow of air towards the wind-
screen and front side window vents;
- turns on rearscreen heating and, if pre-
sent, the wing mirror coils.
When the maximum demisting/defrosting
feature is on, the led on button (7)

DEFROSTING/DEMISTING
BUTTON
((fig. 90)
Pressing button (9)
(turns on demist-
ing/defrosting of the rearscreen and, if pre-
sent, the wing mirror coils.
The turning on of this function is shown by
the turning on of the led on the button.
This function is timed and switches off au-
tomatically after 20 minutes, or pressing the
button again; the function is also switched
off when the engine is stopped and will not
be switched on again the next time the en-
gine is started.
IMPORTANTThe system turns on
rearscreen heating automatically if the tem-
perature is below 3
°C.
IMPORTANTDo not apply stickers on
the inside of the rearscreen over the heat-
ing filaments to avoid damage that might
cause it to stop working properly.
POLLEN FILTER
Have the conditions of the filter checked
by Alfa Romeo Authorised Services at least
once a year, preferably at the onset of sum-
mer.
If the vehicle is used mainly in dusty or pol-
luted areas it should be checked and if nec-
essary replaced, at shorter intervals.
A0A0214m
The filter has the specific capability of com-
bining the mechanical filtering of the air with
an electrostatic effect so that the outside air
admitted to the passenger compartment is
purified and free of particles such as dust,
pollen, etc.
In addition to the above, it also effective-
ly reduces the concentration of pullutants.
The filtering action takes place under all
air inlet conditions and it is clearly most ef-
fective with the windows shut.The failure to replace the
filter may considerably re-
duce the effectiveness of
the climate control system up to
blocking the air flow from the out-
lets and vents.

To change gear smoothly,
the clutch pedal must be
fully depressed. Therefore, there
should be no obstacles on the floor
under the pedal unit: make sure
that any mats are well laid and do
not interfere with the pedals.
WARNING
IMPORTANTReverse gear may only be
engaged with the car completely at a stand-
still. With the engine running, before en-
gaging reverse gear it is necessary to wait
for at least 3 seconds with the clutch pedal
fully depressed to prevent clashing and the
possibility of damaging the gears.
