DESCRIPTIONThe automatic dual zone climate control system regulates the air
temperatures/distribution in the passenger compartment in two areas:
driver side and passenger side.
The system keeps the passenger compartment comfort level constant
and compensates for any variations in external conditions, including
solar radiation detected by a specific sensor.
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 air temperature 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).The system allows the following to be set or adjusted manually:
❒driver's/passenger side air temperature;
❒fan speed (continuous variation);
❒air distribution to 7 positions (driver/passenger);
❒compressor enabling;
❒rapid defrosting/demisting function;
❒air recirculation;
❒heated rear window;
❒system deactivation.
SWITCHING ON THE CLIMATE
CONTROL SYSTEMThe climate control system can be switched on in different ways: we
recommend pressing one of the AUTO buttons and turning the knobs
to set the desired temperatures.
It is possible to select different temperatures for the driver and
passenger, with a maximum difference of 7°C.
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.
During fully automatic operation the only manual intervention is the
possible activation of the following functions:
❒MONO, to align the air temperature and distribution set on the
passenger side with that on the driver side;
❒
air recirculation (keeping the function always either on or
off);

When the parking lights are switched on, the number plate lights and
the front and rear side lights switch on as well (the daytime running
lights (DRLs) remain off however).
The warning light
switches on on the instrument panel.
When the direction indicator stalk is activated the side for the lights
(left or right) can be selected.
AUTOMATIC LIGHTING CONTROL
(AUTOLIGHT) (Dusk sensor)(for versions/markets, where provided)
This infrared LED sensor, combined with the rain sensor and located on
the windscreen, detects the variations in outside brightness depending
on the light sensitivity set with the Set-up Menu: the greater the
sensitivity, the less external light is required to activate the exterior
lights.Activation
The dusk sensor activates when ring nut A fig. 35 is turned to
.In
this way the side lights and dipped headlights are activated
automatically according to the external light level.
IMPORTANT The sensor is unable to detect the presence of fog.
Therefore under these circumstances, these lights must be turned on
manually.
When the lights are turned on by the sensor, the fog lights (for
versions/markets, where provided) and the rear fog lights may be
turned on.
When the lights are automatically switched off, the front and rear fog
lights (if activated) are also switched off. The next time the lights are
switched on automatically, the fog lights must be reactivated manually
(if required).
With the sensor active, it is possible to flash the headlights but the
main beam headlights cannot be switched on. If you need to turn these
lights on, turn ring nut A to position
and turn the dipped
headlights on.
When the lights have been activated automatically and are then
switched off by the sensor, the dipped beam headlights are switched
off first, followed by the side lights a few seconds later.
If the sensor is activated but is malfunctioning, the side lights and
dipped beam headlights are switched on irrespective of the outside
light level and the sensor failure is indicated on the instrument panel
display.
It is also possible to deactivate the sensor and switch on these lights if
necessary.

Move the stalk upwards (unstable position) to limit operation to the
time for which the stalk is held in this position. When released, the
stalk will return to its default position and the wiper will be
automatically stopped.
Do not use the windscreen wiper to remove layers of
snow or ice from the windscreen. In such conditions,
the windscreen wiper may be subjected to excessive
stress and the motor protection, which prevents operation for a
few seconds, may intervene. If operation is not restored, even
after turning the key and restarting the engine, contact Alfa
Romeo Authorized Services.Do not operate the windscreen wiper with the blades
lifted from the windscreen.
"Smart washing" function
Pull the lever towards the steering wheel (unstable position) to operate
the windscreen washer. Keep the stalk pulled for more than half a
second, with just one movement, to operate windscreen washer/wiper
jet at the same time.
The wiper stops working three strokes after the stalk is released. A
further stroke after approximately 6 seconds completes the cycle.RAIN SENSOR(for versions/markets, where provided)
This is an infra-red LED sensor fitted on the car windscreen fig. 37.It is able to detect the presence of rain and consequently manage
windscreen wiping in accordance with the amount of water on the
windscreen.
Activation
The sensor is activated when ring nut A fig. 36 is turned to “automatic”
position (“AUTO” control): the windscreen wiper stroke frequency is
thus adjusted in accordance with the amount of water on the
windscreen.
This frequency can vary from no stroke (no rain - windscreen dry) up
to the 2
ndconstant speed operation (heavy rain - windscreen wet).
The sensitivity of the rain sensor can be adjusted through the Set-up
menu (see paragraph “Menu Items” in this section).
If the engine is stopped with the lever in “automatic” position, when it
is next started no wiping cycle will take place even if it is raining.
This prevents accidental activation of the rain sensor when the engine
is started (e.g. when the windscreen is being washed by hand or
the wipers are stuck to the windscreen when there is ice).
