DESCRIPTION
The automatic dual zone climate control
system regulates the air temperatures
in the passenger compartment in two
areas: driver side and passenger side.
The system maintains comfort inside
the passenger compartment and
compensates for possible variations in
external climate conditions.
NoteThe reference temperature is
22°C for optimal comfort management.
The automatically controlled
parameters and functions are:
❒air temperature at the driver's/front
passenger side vents;
❒air distribution at the driver's/front
passenger side vents;❒fan speed (continuous variation of the
air flow);
❒compressor engagement (for
cooling/dehumidifying the air);
❒air recirculation.
All these functions can be adjusted
manually by operating the system and
selecting one or more functions and
modifying their parameters. Automatic
control of the manually changed
functions will be suspended: the
system will only override the settings for
safety reasons.
Manual selections always have higher
priority than automatic settings and are
stored until the AUTO button is
pressed, except for cases in which the
system intervenes for safety reasons.
You can adjust one function manually
without affecting the automatic control
of 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 temperature of the air sent is
always automatically controlled
according to the temperature set on the
display (except for when the system is
off or in certain conditions when the
compressor is not running).
2)
The system allows the following to be
set or adjusted manually:
❒driver's/passenger side air
temperature;
❒fan speed (continuous variation);
❒air distribution pattern with 7
positions;
❒compressor enabling;
❒rapid defrosting/demisting function;
❒air recirculation;
❒heated rear window;
❒system deactivation.
CLIMATE CONTROL
SYSTEM OPERATING
MODES
The climate control system can be
activated in different ways: it is
advisable to press the AUTO button
and turn the knobs to set the desired
temperatures.
In this way the system operates
completely automatically to adjust the
temperature, quantity and distribution
of the air introduced into the passenger
compartment. It also manages the air
recirculation system and the activation
of the air conditioning compressor.
29

With the compressor on and the engine
running, manual ventilation cannot be
lower than the minimum speed (only
one LED lit).
IMPORTANT With the compressor off,
air cannot be introduced to the
passenger compartment with
a temperature lower than the outside
temperature. Moreover, under certain
environmental conditions, windows
could mist up rapidly since the air is not
dehumidified.
RAPID WINDOW
DEMISTING/DEFROSTING
(MAX-DEF function)
Press the
button to activate (LED
on button on) the windscreen and side
windows demisting/defrosting function.
The climate control system carries out
the following operations:
❒switches on the air conditioning
compressor when climatic conditions
are suitable;
❒deactivates air recirculation;
❒sets maximum air temperature (HI) in
both zones;
❒sets fan speed according to the
engine coolant temperature;
❒directs air flow to windscreen and
front side windows diffusers;❒activates the heated rear window.
❒displays the fan speed (LED G lit).
IMPORTANT The MAX-DEF function
remains on for about 3 minutes from
when the engine coolant reaches the
appropriate temperature.
When the function is activated, the LED
on the AUTO button switches off.
With the function activated the only
possible manual adjustments are
adjusting the fan speed and turning the
heated rear window off.
When the B, C,
or AUTO buttons
are pressed, the climate control system
will turn the MAX-DEF off.
HEATED REAR WINDOW
DEMISTING/DEFROSTING
Press the
button to activate (LED
on button on) heated rear window
demisting/defrosting.
This function switches off automatically
after about 20 minutes or when the
engine is turned off. It is not switched
on automatically the next time the
engine is started.
For versions/markets where provided,
press the
button to activate
demisting/defrosting of exterior rear
view mirrors and heated nozzles (for
versions/markets, where provided).IMPORTANT Do not affix stickers to the
inside of the heated rear window over
the heating filaments, to avoid damage
that might cause them to stop working
properly.
Thermal comfort
windscreen
(for versions/markets, where provided)
Some versions feature a thermal
comfort windscreen which, with the car
exposed to the sun, reduces the
temperature in the passenger
compartment relative to the outside
temperature, thus ensuring greater
comfort.
Humidity sensor
(for versions/markets, where provided)
The humidity sensor helps to prevent
the windows from misting up. For
full functionality, it is advisable to
activate the AUTO function (LED N on).
When the outside temperature is low,
the system could automatically turn the
compressor on and turn air recirculation
off for safer driving.
33

The driver is informed of the fault by the
flashing
symbol (versions with
multifunction display) or
symbol
(versions with reconfigurable
multifunction display). For versions/
markets where provided, a message is
also displayed.
In this case, contact an Alfa Romeo
Dealership.
CAR INACTIVITY
In the event of car inactivity (or if the
battery is replaced), special attention
must be paid to the disconnection
of the battery power supply.
Proceed as follows: detach connector
A fig. 83 (by pressing button B) from
sensor C for monitoring the status
of the battery installed on the negative
battery pole D. This sensor should
never be disconnected from the pole
except if the battery is replaced.
48)
IMPORTANT After turning the ignition
key to STOP and having closed the
driver's side door, wait at least one
minute before disconnecting and then
reconnecting the battery electrical
supply.
JUMP STARTING
When jump starting, never connect the
negative lead (–) of the auxiliary battery
to the negative pole A fig. 84 of the
car battery, but rather to an
engine/gearbox earth point.
49)
IMPORTANT
10) If you wish to run the air
conditioning system, you may
deactivate the Start&Stop system
to allow continuous operation of
the air conditioning system.

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 covered, dry and if
possible well-ventilated premises and
slightly open the windows;
❒check that the handbrake is not
engaged;
❒disconnect the negative battery
terminal and check the battery
charge. Repeat this check once
every three months during storage;
❒if the battery is not disconnected
from the electrical system, checks its
state of charge every thirty days;
❒clean and protect the painted parts
using protective wax;
❒clean and protect the shiny metal
parts using special compounds
available commercially;
❒sprinkle talcum powder on the
windscreen and rear window wiper
rubber blades and lift them off the
glasses;
❒slightly open the windows;❒cover the car with a cloth or
perforated plastic sheet. Do not use
compact plastic sheets which do
not allow humidity to evaporate from
the surface of the car.
❒inflate tyres to +0.5 bar above the
standard prescribed pressure and
check it periodically;
❒do not drain the engine cooling
system;
❒Any time the car is left inactive for
two weeks or more, operate the
air conditioning system with engine
idling for at least 5 minutes, setting
external air and with fan at maximum
speed. This operation will ensure a
suitable lubrication to minimise
possibility of damage to the
compressor when the system is
operated again.
IMPORTANT After turning the ignition
key to STOP, wait at least 1 minute
before disconnecting the electrical
supply to the battery.
