This function automatically demists/defrosts the following: wind-
screen and front side windows, heated spray nozzles, heater ex-
ternal rearview mirrors.
To activate the function on, turn the E knob to the “Defrosting”
symbol identified by the
-symbol. The manual climate control
system will automatically set itself to the following configuration:
❍demisting symbol-from red to orange (to indicate that the
function is on);
❍the heated rear windscreen (and all the installed defrosting
devices) will be turned on. The circular LED around the button
(will light up to indicate that the function is on;
❍the air flow will go to maximum speed (6);
❍air circulation will be opened, if it was closed (the circular LED
about the corresponding button will be off);
❍air mixing to maximum heating;
❍additional electric heater (for versions/markets, where pro-
vided) will be turned on;
❍the compressor will be activated (the circular LED will stay on
to indicate that the AC function is on).
Window demisting
The climate control system is very useful in preventing the windows
from misting up in the event of high levels of humidity.
In the event of considerable outside moisture and/or rain and/or
considerable differences in temperature inside and outside the pas-
senger compartment, proceed as follows to demist the windows:
❍turn A knob to the red section;
❍press F button to disable the air recirculation system (the LED
on the button should be off);

DEMISTING/DEFROSTING
HEATED REAR WINDSCREEN
Press D button (() to turn the function on/off. The function is au-
tomatically deactivated after 20 minutes.
For versions/markets, where provided, pressing the
(button
also defrost/demist the external rearview mirrors, the heated wind-
screen (for versions/markets, where provided) and the heated
spray nozzles (for versions/markets, where provided).
IMPORTANT Do not affix stickers to the inside of the heated rear
windscreen over the heating filaments, to avoid damage that might
cause them to stop working properly.
AIR RECIRCULATION
Press F (v) button so that the LED on the button lights up. It
is advisable to switch air recirculation on while standing in traffic
or in tunnels to prevent the introduction of polluted air.
Do not use the function for a long time, particularly if there are many
passengers on board, to prevent the windows from misting up.
IMPORTANT The air recirculation system makes it possible to reach
the required heating or cooling conditions faster. Do not use the air
recirculation function on rainy/cold days as it would considerably
increase the possibility of the windows misting.
AIR DISTRIBUTION SELECTION
Turn E knob fig. 38 to manually select one of the four possible
air distribution settings in the passenger compartment:
xAir flow to the windscreen and front side window vents to
demist/defrost them.
sAir flow to the front and rear footwell vents. This air distrib-
ution allows the passenger compartment to be warmed up
quickly.
yAir flow distribution between front and rear vents, centre/side
dashboard vents, rear vent and windscreen and front side win-
dow demisting/defrosting vents.
rAir flow distribution to centre/side dashboard vents (pas-
senger’s body).

START&STOP
Manual climate control system
The system will remain set to the air flow setting made by the user
when the Start&Stop function is operated (engine off when speed
is zero). Cooling and heating in the passenger compartment is not
guaranteed in these conditions because the compressor and the
engine coolant pump are both stopped. To privilege climate con-
trol system operation, press the button on the dashboard to turn
the Start&Stop function off.
NOTAIn particularly severe climate conditions it is recommended
to limit the use of the Start&Stop function to prevent the com-
pressor from continuously switching on and off, with following fa-
st window misting and accumulation of humidity with unpleasant
smells in the passenger compartment.
SYSTEM MAINTENANCE
Operate the climate control system for at least 10 minutes every
month during the winter. Have the system checked by Alfa Romeo
Authorized Services before the summer.

You can adjust one function automatically and have the automat-
ic system control all the others. The amount of air introduced into
the passenger compartment is not affected by vehicle speed; it is
electronically controlled by a fan. The air temperature is always au-
tomatically controlled according to the temperature shown on the
display (except for when the system is off or in certain conditions
when the compressor is not running).
The system can manually programme and adjuste:
❍air temperature on driver’s/passenger’s side;
❍fan speed (continuous variation);
❍air distribution to 7 positions;
❍climate control compressor enabled;
❍fast demisting/defrosting function;
❍air recirculation;
❍heated rear windscreen;
❍turning the system off.
DESCRIPTION
The automatic dual zone climate control system regulates the tem-
perature in the passenger compartment in two areas. The system
keeps the comfort in the passenger compartment constant and
compensates for variable external conditions.
NOTEThe reference temperature is 22°C for optimal comfort man-
agement.
The automatically controlled parameters and functions are:
❍air temperature delivered to driver/front passenger vents;
❍air distribution to driver/front passenger vents;
❍fan speed (continuous air flow variation);
❍switching the compressor fan on (for cooling/dehumidifying
the air);
❍air recirculation.
All these functions can be manually adjusted by operating the sys-
tem and selecting one or more functions and modifying their pa-
rameters. Automatic control of the manually changed functions will
be suspended: the system will only override your settings for safe-
ty reasons.
Manual selections will always have higher priority over automatic
settings and will be stored until the AUTO button is pressed, except
for the cases in which the system will intervene for particular, safe-
ty-related reasons.
The climate control system uses an average radi-
ating temperature sensor installed under a cover
below the inner rearview mirror. To ensure opti-
mal operation of the climate control system, do not ob-
struct the detection cone of this sensor with any object.

ADJUSTING THE AIR TEMPERATURE
Turn A or L knob to right or left to adjust the air temperature: A
knob for the front left-hand area, L knob for the front right-hand
area of the passenger compartment. The set temperatures are
shown on the display.
Press the MONO button to align the air temperature between the
two zones.
Turn L knob to go back to the separate management of air tem-
peratures in the two zones.
Turn the knobs fully clockwise or anti-clockwise to engage respec-
tively HI (maximum heating) or LO (maximum cooling). To de-
activate these functions, rotate the temperature knob to the de-
sired temperature.
SWITCHING THE CLIMATE CONTROL SYSTEM ON
The system can be turned on in different ways: you are recom-
mended to press the AUTO button and turn the knobs to set the re-
quired temperatures.
In this way the system operates completely automatically to ad-
just the temperature, quantity and distribution of the air introduced
into the passenger compartment. It also manages the air recircu-
lation system and the enablement of the air conditioning com-
pressor.
During fully automatic system operation, you can change at any
time the set temperatures, air distribution and fan speed by using
the relevant buttons or knobs: the system will automatically change
its settings to adjust to the new requirements.
During fully automatic operation (AUTO), the word AUTO will dis-
appear if the air distribution and/or flow rate and/or engagement
of the compressor and/or recirculation settings are changed.
In this way the climate control system will continue to automati-
cally manage all functions except for those that have been manu-
ally adjusted. There is only one fan speed in all the areas of the
passenger compartment.

In AUTO mode, the climate control system automatically manage
air distribution settings; the LED on H buttons are off.
When set manually, the set distribution is shown by the LEDs on
the selected buttons.
In combined function mode the relevant function is enabled si-
multaneously with those already set by pressing the correspond-
ing button. If a button whose function is active yet is pressed, the
operation is cancelled and the corresponding LED goes off. To re-
store automatic control of the air distribution after a manual se-
lection, press the AUTO button.SETTING THE AIR DISTRIBUTION
Press H (//) buttons to manually select one of the sev-
en possible air distribution settings:
Air flow to the windscreen and front side window vents to
demist/defrost them.
Air flow from central and side dashboard vents to ventilate
the chest and the face during the hot season.
Air flow to the front and rear footwell vents. This air distribu-
tion setting heats the passenger compartment most quickly,
giving a prompt sensation of warmth.

Air flow distribution between footwell vents (hotter air) and
centre and side dashboard vents (cooler air). This distribution
setting is useful in spring and autumn on a sunny day.

Air flow distributed between foot well vents and windscreen
and front side window defrosting/demisting vents. This distri-
bution setting allows to warm up the passenger compartment
and prevents the windows from misting up.

Air flow distribution between windscreen demisting/defrosting
vents and side and central dashboard vents. This setting allows
air to be sent to the windscreen in conditions of strong sunlight.


Air flow distribution to all vents in the car.

It is advisable not to use the air recirculation func-
tion when the outside temperature is low to pre-
vent the windows from rapidly misting up.
Turning the AQS (Air Quality System)
function on
The AQS function automatically activates internal air recirculation
when the outside air is polluted (e.g. in traffic queues and tunnels).
IMPORTANT With the AQS function active, after the internal air
recirculation system has been running for a certain time, the cli-
mate control system enables the intake of outside air for approx-
imately 1 minute. This takes place regardless of the pollution lev-
el of the outside air.
IMPORTANT The air recirculation system makes it possible to reach
the required heating/cooling conditions faster. It is, however, in-
advisable to use it on rainy/cold days as it would considerably in-
crease the possibility of the windows misting up inside (especially
if the climate control system isoff). When the outside tempera-
ture is low, recirculation is forced off (air drawn from the outside)
to prevent the windows misting up.
In automatic operation inside air recirculation will be controlled auto-
matically by the system according to outside environmental condi-
tions.
AIR RECIRCULATION AND AQS
(Air Quality System) FUNCTION
The air recirculation is managed according to the following oper-
ating logics:
❍automatic engagement: A word on B button on;
❍forced engagement (air recirculation always on): LED onv
A button on and A word off;
❍forced disengagement (air recirculation always off, air taken
from the outside): the LED on
vA buttons will switch off
and the A word on B button will switch off.
Forced on/off mode can be selected by pressing button
vA..
When
g(E button off ) is pressed, the climate control system
automatically activates air recirculation (the LED on
vA but-
ton should be on). Press
vA button to turn external air recir-
culation on (LED on button lit) and vice versa.
AQS (Air Quality System) function cannot be operated when
g
button is pressed (LED on button off).

CLIMATE CONTROL SYSTEM COMPRESSOR
Press C to turn the compressor on/off (the LED on the button will
light up when the compressor is on). The system remembers that
the compressor has been switched off, even after the engine has
stopped.
When the compressor is switched off the system deactivates air re-
circulation to prevent the windows from misting up and deactivates
the AQS function. In this case, although the system is capable of
maintaining the required temperature, the AUTO LED will go out.
The temperatures will flash for a few seconds if the required tem-
perature cannot be maintained.
To restore automatic control for switching on the climate control
compressor, press C button again or press the AUTO button.
With compressor off:
❍if the outside temperature is higher than the set one, the sys-
tem will not be able to satisfy the request. The temperature
value will then flash on the display for a few seconds;
❍the fan speed can be manually reset.
When the compressor is on and the engine is running, manual ven-
tilation cannot drop under the maximum speed (only one LED on).
IMPORTANT With the climate control compressor off, it is not pos-
sible to admit air into the passenger compartment with a tempera-
ture below the outside temperature; moreover, under certain envi-
ronmental conditions the windows could mist up very quickly since
the air cannot be dehumidified.
RAPID WINDOW DEMISTING/DEFROSTING
(MAX-DEF function)
Press-to turn windscreen and side window demisting/defrosting
function on (LED on button lit). The climate control system carries
out the following operations:
❍switches on the climate control compressor when climatic con-
ditions allow;
❍turns air recirculation off;
❍sets maximum air temperature (HI) in both zones;
❍sets proper fan speed according to the engine coolant tem-
perature;
❍directs air flow to the windscreen and front side windows vents;
❍theheatedrearwindscreenisturnedon
❍shows fan speed (LED G lit).
IMPORTANT The MAX-DEF function will remain on for approximately
3 minutes from when the engine coolant reaches adequate tem-
perature.
The LED on the AUTO button will go out when the function is on.
With the function activated the only possible manual adjustments
are adjusting the fan speed and the turning the heated rear wind-
screen off. By pressing B, C,
-or AUTO buttons, the climate
control system will turn the MAX-DEF off.
