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.

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.

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 is off). 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 on v
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).

NOTEWhen the Start&Stop function is active (engine off and
vehicle speed zero), the automatic recirculation management is
turned off always taking air in from outside, to reduce the proba-
bility of window misting up (as the compressor is off).
SUPPLEMENTARY ELECTRIC HEATER
(for versions/markets where provided)
This device speeds up passenger compartment warming when it is
very cold. The additional heater turns off automatically after reach-
ing the required comfort conditions.
Automatic dual zone climate control system
(for versions/markets, where provided)
The supplementary electric heater is operated automatically ac-
cording to environmental conditions and when the engine is run-
ning.
Manual climate control system
The supplementary heater is activated automatically by turning A
knob to the end of the red section and setting the fan (knob B)
to at least the 1
stspeed.
IMPORTANT NOTES
The heater only works if the outside temperature and engine coolant
temperature are low.
The heater will not activate if the battery voltage is too low.
START&STOP
Automatic climate control system
The automatic climate control system manages the Start&Stop
function (engine off when speed is zero) to ensure adequate com-
fort inside the passenger compartment.
Specifically, the Start&Stop function is turned off when the weath-
er is particularly hot or cold to guarantee an adequate level of com-
fort inside the passenger compartment; therefore, the engine will
not be stopped during these transient conditions, even if the speed
is zero.
When the Start&Stop is on and the engine is off at zero speed,
the climate control system will turn the engine back on if the in-
side temperature conditions should rapidly deteriorate (or if the
user asks for maximum cooling – LO – or quick demisting –
MAX-DEF).
With the Start&Stop function on and engine off at zero speed,
air flow is reduced to the minimum to main comfort conditions in-
side the passenger compartment as long as possible when the sys-
tem is in AUTO mod (LED N on).
The climate control system attempts to manage the discomfort
caused by the engine stopping (compressor and engine coolant
pump off) but operation of the climate control system can be priv-
ileged by turning the Start&Stop off by pressing the button on
the dashboard.
NOTEIn particularly severe climate conditions it is recommen-
ded 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.

Keep your speed down when snow chains are fit-
ted - do not exceed 50 km/h. Avoid potholes, steps
and pavements and also avoid driving for long dis-
tances on roads not covered with snow to avoid damag-
ing the car and the road surface.
SNOW CHAINS
The use of snow chains should be in compliance with local regu-
lations. Snow chains may be fitted only to the front wheel tyres
(drive wheels).
Check the tension of the chains after the first few metres have been
driven.
Use reduced bulk snow chains:
– All versions: for 195/55 R16”, 205/55 R16” and 225/45
R17” size tyres use low-clearance snow chains with a maximum
protrusion beyond the tyre profile of 9 mm.
IMPORTANT The space-saver wheel cannot be fitted with snow
chains. If a front (drive) wheel is punctured and snow chains must
be used, you must remove a normal wheel from the rear and re-
place this one with the space-saver wheel. In this way, with two
normal drive wheels, it is possible to use snow chains.
STORING THE CAR
If the car is to be left inactive for longer than a month, the following
precautions should be noted:
❍park the car in a dry, covered and, if possible, ventilated area;
engage a gear and check that the handbrake is not engaged;
❍disconnect the negative battery terminal and check battery
charge. Repeat this check once every three months during stor-
age;
❍clean and protect painted areas using protective wax;
❍clean and protect the shiny metal areas using special com-
mercially-available products;
❍sprinkle talcum powder on the rubber windscreen and rear win-
dow wiper blades and lift them off the glass;
❍slightly open the windows;
❍cover the car with a fabric or perforated plastic sheet. Do not
use compact plastic sheets which do not allow humidity to evap-
orate from the surface of the car.
❍inflate tyres to a pressure of +0.5 bar above the normal spec-
ified pressure and check the pressure at regular intervals;
❍if you have not disconnected the battery, check the battery
charge every thirty days;
❍do not drain the engine cooling system.
