Speed limit exceeded (red)
(for versions/markets, where provided)
The warning light (for versions/markets where pro-
vided) comes on when the speed exceeds 120 km/h.
When the car exceeds the speed limit set in the setup Menu (e.g.
120 km/h), on some versions a message and a symbol are shown
in the display and an acoustic signal is activated.

Always drive at a speed appropriate to the traffic
conditions, the weather and the laws in force. The
engine may be turned off while the DPF light is on;
however, repeated interruption of the regeneration process
may result in premature degradation of the engine oil.
For this reason, it is always advisable to wait for the light
to go off before turning off the engine, following the in-
structions appearing above. It is not a good idea to com-
plete DPF regeneration with the vehicle stationary.Generic fault (amber)

The warning light turns on in the following circumstances:
Contact Alfa Romeo Authorized Services as soon as possi-
ble to eliminate the fault.

Headlight sensor (Automatic headlight/dusk
sensor sensitivity adjustment)
(for versions/markets, where provided)
This function is used to turn the headlights on or off according to
external lighting conditions.
The dusk sensor sensitivity can be adjusted according to 3 levels
(level 1= minimum sensitivity, level 2= average sensitivity, level
3= maximum sensitivity); the greater the sensitivity set, the less
the external light variation needed to control turning on the lights
(e.g. with a setting on level 3 at sunset the headlights are expected
to come on in relation to levels1 and 2).
Proceed as follows to set:
– briefly press SET ESC: the previously set brightness level flash-
es in the display;
– press “
Ò▲“ or “▼“ to select;

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.

DEMISTING/DEFROSTING
HEATED REAR WINDSCREEN
Press(to turn heated rear windscreen demisting/defrosting func-
tion on (LED on button lit). 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, pressing the
(button it is al-
so possible to defrost/demist the external rearview mirrors (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 on 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, limits the extent of temperature in-
crease inside the passenger compartment, thus ensuring greater
comfort.
Humidity sensor (for versions/markets, where provided)
The humidity sensor prevents the windows from misting up. For
full operation, it is advisable to turn the AUTO on (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.
TURNING THE CLIMATE CONTROL SYSTEM OFF
Pressgbutton (LED on button off):
❍air recirculation is on, thus isolating the passenger compartment
from the outside;
❍the compressor is off;
❍the fan is off.
❍the heated rear windscreen can be switched on or off.
❍the AQS (Air Quality System) function cannot be turned on.
IMPORTANT The climate control system control unit stores the tem-
peratures set before the system was switched off and restores
the same conditions when any button of the system is pressed (ex-
cept for D button).
Press AUTO button to restart the climate control system in fully
automatic mode.
