WARNING LIGHT FAILURE
This is shown on the reconfigurable multifunction display when a fault is detected to one of the
warning lights indicated.
POSSIBLE PRESENCE OF ICE ON THE ROAD
The symbol √+ message are shown by the reconfigurable multifunction display and the buzzer
sounds, when the outside temperature reaches or falls below 3° C to warn the driver about the pos-
sible presence of ice on the road. The buzzer lasts for 2 seconds while the outside temperature flash-
ing message is displayed for about 10 seconds; after that time, only the symbol
√is displayed until
the temperature goes beyond 6° C or the engine is stopped. If during travelling, after the signal of
possible presence of ice on the road, temperature goes beyond 6° C, the symbol disappears and if
the temperature reaches again 3°C, a new message (with outside temperature flashing) will be dis-
played together with the corresponding symbol
√accompanied by the sound signal.

AIR TEMPERATURE
ADJUSTMENT KNOB
Turn the ring of knob (1-fig. 95) clock-
wise or counter-clockwise respectively to
higher or lower the temperature of the air
admitted to the passenger compartment.
AIRDISTRIBUTION KNOB
Turning the knob ring (3-fig. 95), the
following positions are selected in sequence:
Air flow towards the upper centre,
front centre vents and from the front
and rear outlets with the possibility of ad-
justment using the controls on the actual
vents.
Splitting of air flow between the pre-
vious vents and the lower part of the
passenger compartment.
Air flow to the lower part of the pas-
senger compartment (front and rear).
Splitting of air flow between the
windscreen/front side windows and
the lower part of the passenger compart-
ment.
Air flow towards the windscreen and
front side windows for demist-
ing/defrosting.
Flow air to allow quick demist-
ing/defrosting of the windscreen
and front side windows, turning on
rearscreen heating for defrosting/demisting
(function called
MAX-DEF).

FAN SPEED ADJUSTMENT
KNOB
Turning the ring of knob (2-fig. 95) it is
possible to select one of the fan speeds to per-
sonalise the amount of air admitted to the pas-
senger compartment.
Position0turns off the fan and automati-
cally engages inside air re-circulation (shown
by the lighting up of the led next to the but-
ton4

outside air to the car.
To switch off inside air re-circulation, press
button (4)
v.

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
Pressing button (4-fig. 95)vacti-
vates inside air re-circulation and the led next
to the button lights up.
In this case the climate control system di-
rectly treats the air contained in the pas-
senger compartment, the fan is on.
To switch the air re-circulation feature off
and withdraw air from outside, press the but-
ton again.The inside air- re-circula-
tion system makes it pos-
sible to reach the required
“heating” or “cooling” conditions
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 con-
trol system is off.
It is advisable to turn on
the inside air re-circulation
system
vin queues or
tunnels to avoid admitting pollut-
ed air from outside. The prolonged
use of this function should howev-
er be avoided, especially with sev-
eral persons on board, to avoid the
possibility of the windows misting
inside.
REARSCREEN HEATING
ON/OFF BUTTON
Pressing the button (5-fig. 95) turns on
demisting/defrosting of the rearscreen, and
if present, the wing mirror heating coils; si-
multaneously the led next to the button
turns on. This function is timed and switched
off automatically after 20 minutes. To turn
off earlier, press the button again.
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 which might
cause it to stop working properly.
When cleaning the inside
of the rearscreen, take
care not to damage the
heating filaments.

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.

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.
