CLIMATE CONTROL SYSTEM (cooling)
Proceed as follows to cool the passenger compartment:
❍turn A knob to the blue section;
❍press F button to turn air recirculation on (the circular LED
around the button should be on);
❍turn E knob to r;
❍press B button to turn the climate control system on and turn C
knob to at least 1 (1stspeed); for faster action, turn C knob to 6
(maximum fan speed).
Adjusting cooling
❍turn A knob to right to increase the temperature;
❍press F button to turn air recirculation system off (the circular
LED around the button should be off);
❍turn C knob to reduce fan speed.
PASSENGER COMPARTMENT HEATING
Proceed as follows to rapidly heat the passenger compartment:

AUTOMATIC DEMISTING/DEFROSTING
(MAX-DEF function)
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);
❍turn E knob to -and move it to position u(B-fig. 38a) if
demisting does not take place;
❍turn C knob to the 2ndspeed.

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 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.
A0K0083m
Four other positions are provided (see diagram below):
v(A Position) Air flow distribution between centre/side dash-
board vents, rear vent and windscreen and front side window
demisting/defrosting vents. This distribution setting ventilates
the passenger compartment and prevents the windows from
misting up.
u(B Position) Air flow distributed between foot well vents and
windscreen and front side window defrosting/demisting vents.
This distribution setting allows warms up the passenger com-
partment and prevents the windows from misting up.
w(C Position) Air flow distribution between footwell vents
(warmer air) and centre/side dashboard vents and rear vent
(cooler air).
-(D Position) Automatic demisting/defrosting activation (see
description of the previous pages).

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.
