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.

AIR TEMPERATURE ADJUST-
MENT KNOBS
(fig. 101)
Turning the rings of knobs (2or6), clock-
wise or counter-clockwise, respectively high-
ers or lowers the temperature of the air re-
quired respectively in the left zone (knob 2)
or right zone (knob 6) of the passenger
compartment. The temperatures set are
shown on the displays (1) and (5) above
the knobs.
Separate operation of the temperatures set
is restored automatically using knob (6).
Turning the knob rings clockwise or
counter-clockwise until they reach the ex-
treme selections HIorLO, the maximum
heating or cooling functions are respective-
ly engaged:

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.

LO function
(highest cooling power - fig. 103)
This is turned on setting on the display a
temperature below 16,5°C; this setting is
shown on both displays.
This function can be engaged when re-
quiring to cool the passenger compartment
as quickly as possible, exploiting the maxi-
mum potential of the system.
The function cuts off air heating, engages
inside air re-circulation (to prevent admitting
hot air to the passenger compartment) and
the climate control compressor, takes air dis-
tribution to
REand the fan speed as set
by the system.
All manual settings are possible with this
function on.
To switch the function off, simply turn the
ring of knob (2) or (6) of the temperature
set on a value above 16,5°C; the opposite
display will show 16,5°C.
Pressing key (13)
AUTOthe display will
show a temperature of 16,5°C and returns

AIR DISTRIBUTION SELECTION
BUTTONS
(fig. 107)
Pressing one or more buttons (10) it is
possible to manually choose one of the 5
possible air distributions to the passenger
compartment:
REFlow of air to the dashboard centre
and side outlets and rear outlet.E
R
ZESplitting of the air flow between the
vents to the lower part of the pas-
senger compartment (warmest air)
and the dashboard centre and side
outlets and the rear outlet (coolest
air). The air flow distribution is par-
ticularly useful in spring and autumn,
when the sun is shining.
ZAir flow towards the front and rear
lower parts of the passenger com-
partment. Due to the natural tenden-
cy of heat to spread upwards, this
type of distribution allows heating of
the passenger compartment in the
shortest time, also giving a prompt
feeling of warmth to the coldest parts
of the body.
A0A0208b
Q
ZSplitting of the air flow between the
windscreen and side window defrost-
ing/demisting vents and the lower
part the of the vehicle. This type of air
distribution allows satisfactory heat-
ing of the passenger compartment
while preventing misting of the win-
dows.
QAir flow to the windscreen and front
side window vents to demist or de-
frost them.IMPORTANTPressing one of these but-
tons turns on (led on button itself on)
or off (led on button off) the associ-
ated functions if the combination cho-
sen is among the 5 possible ones; if
not it only activates the main function
of the button pressed, without the
possibility of turning off with anoth-
er press (at least in one distribution
the air flow should be spread in the
passenger compartment).
To restore automatic air distribution
control after a manual selection, press
button (13)

INSIDE AIR RE-CIRCULATION
ON/OFF BUTTON
(fig. 110)
Inside air re-circulation is controlled ac-
cording to three operating logics:
- automatic control, indicated by the turn-
ing on of the right led on the button;
- forced engagement (inside air re-circula-
tion always on), indicated by the turning on
of the left led on the button (and by the right
led going off at the same time);
- forced switching off (inside air re-circula-
tion always off with air inlet from outside),
indicated by the turning off of both leds.
These operating conditions are obtained
pressing in sequence the inside air re-circu-
lation button (8)
v.
When inside air re-circulation is controlled
automatically by the system, the right led
on the air re-circulation button (8)
v
stays on all the time and the left led shows
the air re-circulation condition:
on= air re-circulation operating;
off= air re-circulation off.
If inside air re-circulation has been turned
on or off manually, the led on button (13)
AUTOturns off.In automatic operation , inside air re-circu-
lation is turned automatically when the an-
tipollution sensor detects the presence of pol-
luted air, for example in cities, queues, tun-
nels and operation of the windscreen wash-
er (with the typical smell of spirits).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.
A0A0212b
With the outside temper-
ature below 4°C the cli-
mate control compressor is
unable to work. It is therefore un-
advisable to use the inside air re-
circulation feature
vwith low
outsidetemperature, as the win-
dows may quickly mist over.

BUTTON
(MAX-DEF FUNCTION)
(fig. 112)
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/defrost-
ing feature is on, the led on button (7)
-, the led on the rearscreen heating button
(9)
(and the led on button (14)√turn on; at the same time the leds on but-
ton (8)
v.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.
When the maximum demisting/defrost-
ing function is on, the only manual opera-
tion possible are manual adjustment of the
fan and switching rearscreen heating off.Pressing one of the following buttons
again: (7)

es off the maximum demisting/defrosting
function, restoring the operating conditions
of the system prior to turning it on, in ad-
dition to activating the last function required,
if any.
