DEMISTING
AND/OR DEFROSTING THE
WINDSCREEN AND FRONT SIDE
WINDOWS, REARSCREEN AND
WING MIRRORS
(MAX-DEF FUNCTION)(fig. 97)
Proceed as follows:
- turn the ring of the air distribution knob
(3)to the
-symbol.
The climate control activates all the functions
necessary to quicken demisting/defrosting of
the windscreen and side windows with tim-
ing (switching off automatically after 3 min-
utes), as follows:
- switches off air re-circulation, if engaged;
- sets the maximum air temperature;
- 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 max def function is on, the fol-
lowing are on: the led next to the rearscreen
heating button (5)
(.
IMPORTANTIf the engine is not hot
enough, the function does not immediate-
ly engage the pre-established fan speed, to
restrict the inlet of air to the passenger com-
partment that is not warm enough to demist
the windows.
After demisting/defrosting, simply use the
controls to maintain the optimum conditions
of vision and comfort.
IMPORTANTThe hotter the engine the
more effective defrosting will be.IMPORTANTIn cases of heavy damp
and/or rain and/or big differences in tem-
perature between inside the car and outside,
it is advisable to proceed as follows to
demist the windows:
- air re-circulation off, led next to button
(4)
voff;
- pointer of knob (2) at fan second speed
at least;
- pointer of knob (3) on symbol
≤with
the possibility of passing to position
yif
more misting is noted;
To defrost/demist the rearscreen, press
button (5)
(, led next to button on.

HEATING (fig. 98)
To obtain the temperature required, pro-
ceed as follows:
- temperature adjustment knob pointer (1)
on the red sector as required;
- air quantity adjustment knob pointer (2)
on the fan speed required to personalise the
amount of air admitted;
- air distribution knob pointer (3) on the
required position.
To obtain the maximum heating power pro-
ceed as follows:
- knob pointer (1) as far as it will go clock-
wise (maximum temperature red sector);
- knob pointer (2) on maximum fan
speed;
- air distribution knob pointer (3) on the
required position (position
w) is recom-
mended.
IMPORTANTTo be able to obtain sat-
isfactory passenger compartment warming,
the engine should have reached normal op-
erating temperature.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 mentioned func-
tions, is also reduces the concentration of
pollutants.
The filtering action is active in all air inlet
conditions and it is clearly more effective
with the windows closed.
Have the conditions of the filter checked
at least once a year, preferably at the on-
set of summer by Alfa Romeo Authorised
Services.If the car is habitually used in dusty or pol-
luted areas, the filter should be checked and
replaced at shorter intervals than those spec-
ified in the Programmed Maintenance
Schedule.
If the filter is not replaced
the efficiency of the cli-
mate control system may
be seriously compromised up to
blocking the air flow at the outlets
and vents.

AUTOMATIC TWO-ZONE CLIMATE CONTROL SYSTEM
(for versions/markets where applicable)
To start the system (fig. 99):
- turn the knob rings to set the required
temperatures (driver’s side - passenger’s
side).
- press the
AUTObutton.
IMPORTANTThe climate control sys-
tem makes it possible to personalise the
temperatures required on the two side with
a maximum difference of 7°C between the
driver’s side and the passenger’s side.
IMPORTANTThe climate control com-
pressor only works with the engine running
and an outside temperature above 4°C.
With an outside tempera-
ture below 4°C the climate
control compressor is un-
able to work. It is therefore unad-
visable to use the inside air re-cir-
culation feature
vwith a low
temperature as the windows might
mist over quickly.
For further details about the system and
how to make the best use of it, read the
instructions given in pages that follow.
A0A0203b
fig. 99
The coolant used for the
climate control system is
R134a which meets cur-
rent regulations and does not harm
the environment in the event of ac-
cidental spillage.
Absolutely avoid the use of oth-
er fluids which are incompatible
with the system components.
GENERAL
The car is fitted with a two-zone climate
control system, controlled by an electronic
control unit which makes it possible to sep-
arately adjust the air temperature on the dri-
ver’s side and on the passenger’s side. To
obtain optimum temperature control in the
two areas of the passenger compartment,
the system has an outside sensor, a pas-
senger compartment sensor and a two-zone
sun ray sensor.

GETTING TO KNOW YOUR CAR
109
- 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.). 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 recirculation, air
flow, air capacity. This operation inhibits the
incipient misting sensor signal until the
AUTObutton is pressed again or the next
time the ignition key is turned toMAR.
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 spirit).
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.
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: 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. 102)
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.

IMPORTANTThe system automatically
turns on rearscreen heating if the tempera-
ture 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.
A0A0214b
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 mentioned func-
tion, it also reduces the concentration of pol-
lutants.
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.
