AUTOMATIC
TWO-ZONE CLIMATE
CONTROL SYSTEM
(for versions/markets,
where provided)
DESCRIPTION
The car is fitted with a two-zone climate
control system which makes it possible
to separately adjust the air temperature
in the two passenger’s compartment ar-
eas to reach the required comfort.
To obtain top control of both zones, the
system is fitted with outside temperature
sensor, passenger’s compartment tem-
perature sensor and bilateral sun radia-
tion sensor.
The climate control system automatically
controls and adjusts the following pa-
rameters and functions:
❒air temperature at driver/passengers
vents;
❒fan speed;
❒air distribution at driver/passenger
vents;
❒compressor activation;
❒air recirculation.
The following parameters and functions
can be set or changed manually:
❒required temperature;
❒fan speed;
❒air distribution on seven levels;
❒compressor on/off;
❒window demisting/defrosting;
❒air recirculation.
The system is fitted with AQS (Air Qual-
ity System) sensor (where provided),
that turns on air recirculation automati-
cally when it detects the presence of out-
side polluted air (for example in queues
and tunnels).
Where provided, the system is integrat-
ed with an anti-misting sensor A-fig. 42
set behind the driving mirror, capable of
“monitoring” a preset internal area of the
windscreen and of intervening automat-
ically to prevent or to reduce window mist-
ing up, through a proper strategy. This
sensor can be deactivated through any
manual system control when the strate-
gy is operating. The sensor is enabled at
each start-up and in any case when the
user presses one of the AUTO buttons.

“FOLLOW ME HOME”
DEVICE
This function allows the illumination of
the space in front of the car for a pre-
set period of time.
Activation
Pull the stalk towards the steering wheel
within 2 minutes from when the engine
is turned off.
At each single movement of the stalk,
the staying on of the lights is extended
by 30 seconds up to a maximum of 3.5
minutes; then the lights are switched off
automatically.
Each time the stalk is operated, the
3
warning light turns on together with the
message on the display (see section
“Warning lights and messages”).
Deactivation
Keep the stalk pulled towards the steer-
ing wheel for more than 2 seconds.
AUTOMATIC HEADLIGHTS
SENSOR (daylight sensor)
(for versions/markets,
where provided)
It detects the changes of the external
light intensity of the car according to the
light sensitivity set: the greater the sen-
sitivity is, the smaller the amount of ex-
ternal light necessary to control the
switching-on of the external headlights
will be.
The daylight sensor sensitivity can be ad-
justed through the “Setup Menu” of the
display (see “Reconfigurable multifunc-
tion display” in this section).
Activation
Turn the knurled ring A-fig. 44to
2A:
in this way, the automatic activation of
the side/taillights and dipped beam
headlights is simultaneously enabled ac-
cording to outside brightness.
With lights switched on automatically
and in the presence of a switching off
control by the sensor, the main beams
will be switched off first and a few sec-
onds after also the sidelights.Deactivation
As a result of the sensor control, the
dipped beam headlights will switch off
and, after a few seconds, sidelights will
switch off too. The sensor is not able
to detect the fog presence, lights shall
therefore be switched on manually.
Failure warnings
Headlight sensor failure is shown by a
dedicated message on the display (see
section “Warning lights and mes-
sages”).

OF THE CAR
The rain sensor is activated automatical-
ly moving the right-hand stalk to position
1-fig. 47and it has a range of adjust-
ment that gradually varies between wiper
stationary (no wiping) when the wind-
screen is dry, to wiper at second speed
(continuous, medium) with heavy rain.
Turning the knurled ringA-fig. 47it
is possible to increase the sensitivity of
the rain sensor, obtaining a quicker
change from stationary (no wiping)
when the windscreen is dry, to first con-
tinuous speed (continuous, slow). This
action is confirmed by one wiping
stroke.
Operating the windscreen washer with
the rain sensor activated (stalk at posi-
tion1-fig. 47) the normal washing
cycle is performed at the end of which
the rain sensor resumes its normal au-
tomatic function. “Smart washing” function
Pulling the stalk towards the steering
wheel (unstable position) operates the
windscreen washer.
Keeping the stalk pulled with just one
movement it is possible to operate the
washer jet and the wiper at the same
time; the wiper actually comes into op-
eration automatically when the stalk is
pulled for more than half a second.
The wiper stops working 3 strokes after
releasing the stalk; a further stroke af-
ter about 6 seconds will complete the
wiping operation.
RAIN SENSOR
(for versions/markets,
where provided)
The rain sensor A-fig. 48, located be-
hind the driving mirror, is an electronic de-
vice combined with the windscreen wiper
which has the purpose of automatically
adjusting the number of wipes during in-
termittent operation, to intensity of the
rain. All the other functions controlled by
the right-hand stalk remain unchanged.

CORRECT USE
OF THE CAR
Rain sensor shall be de-
activated when washing
the car at automatic car-
wash.
Make sure the rain sen-
sor is deactivated if
there is ice on the wind-
screen.
Removing the electronic key from the
ignition device, the rain sensor is deac-
tivated and the next time the engine is
started it will not be reactivated even if
the stalk has remained in position 1-
fig. 47. In this case to activate the rain
sensor, simply move the stalk to 0or2
and then back to 1.
When the rain sensor is reactivated in
this way, the wiper performs one stroke,
even if the windscreen is dry, to indicate
that reactivation has occurred.IMPORTANTIn the event of rain sen-
sor failure, windscreen wiper operation
with right-hand stalk at 1-fig. 47is in-
termittent. If failure takes place during
automatic operation, the system will
keep the last wiper operating condition.
Moving the stalk to other positions, op-
eration is however guaranteed.
The rain sensor is able to recognize and
automatically adjust itself in the pres-
ence of the following particular condi-
tions:
❒impurities on the controlled surface
(salt, dirt, etc.);
❒difference between day and night.Failure warnings
Sensor failure is indicated by a dedicat-
ed message on the display (see section
“Warning lights and messages”).

PARKING SENSORS
(for versions/markets, where provided)
Parking sensors inform the driver about
the presence of obstacles behind the car.
This system is therefore an aid for the
driver when parking the car since it de-
tects obstacles out of the driver’s sight
range.
The presence and the distance from the
car of an obstacle is indicated by a warn-
ing buzzer - as the distance from the ob-
stacle decreases, the acoustic alarm be-
comes more frequent.Parking manoeuvres
however are always
under the driver’s responsibil-
ity that shall always check the
absence of people (specially
children) or animals in the ma-
noeuvre space. This system is
just a help for the driver but
she/he shall never reduce at-
tention during dangerous ma-
noeuvres even if performed at
low speed.
WARNINGACTIVATION
Sensors are activated automatically,
with electronic key fitted into the igni-
tion device, when the reverse gear is en-
gaged.
Sensors will deactivate when exceeding
18 km/h.
When sensors are on, rear indicators will
sound warning signals as soon as an ob-
stacle is detected: as the distance from
the obstacle decreases, the acoustic
alarm becomes more frequent.
When the distance between the car and
the obstacle is less than 30 cm, the
acoustic alarm becomes continuous.
The acoustic alarm will stop immediately
as distance raises. The acoustic alarm is
constant if the distance measured by
central sensors is unvaried, whereas if
this situation takes place for side sen-
sors the acoustic alarm is muted after
about 3 seconds to prevent sound indi-
cations when performing manoeuvres
near walls.

BUZZER
The presence of any obstacle and its dis-
tance from the car is indicated by the
buzzers installed in the rear area of the
passenger compartment.
SENSOR DETECTION RANGE
Sensors enable the system to monitor
he rear part of the car.
Actually their position covers the central
and side areas of the rear part of the car.
An obstacle positioned at central area is
detected at a distance less than approx.
1.40 m.
An obstacle positioned at side area is de-
tected at a distance less than 0.6 m.
For proper operation,
the parking sensors shall
always be clean from
mud, dirt, snow or ice. When
cleaning the sensors, take the
utmost care to prevent their
damaging; do not use therefore
dry or rough clothes. Sensors
shall be washed with clean wa-
ter and car detergent, if re-
quired. In washing stations,
clean sensors quickly keeping
the vapour jet/high pressure
washing nozzles at 10 cm at
least from the sensors.
Repainting the bumpers
or touch-up in the sen-
sor area, if required,
shall be carried out at Alfa
Romeo Authorized Services on-
ly. Incorrect repainting may im-
pair regular operation of the
parking sensors.
