“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)
(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”).

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-
tion 1-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
(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.

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 0or 2
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
(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.

Obstacles are detected by 4 sensors lo-
cated in the rear bumper fig. 86.
A0F0232mfig. 86
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.

If a failure is indicated, stop the car, turn
the engine off and then clean the sen-
sors. Make sure to be far from possible
ultrasound sources (e.g.: truck pneu-
matic brakes or pneumatic hammers).
If failure cause has been eliminated the
system will resume regular operation
and message + symbol on the display
will turn off.
If the warning light stays on, contact Al-
fa Romeo Authorized Services to have
the system inspected, although the sys-
tem keeps on working. If the failure de-
tected does not impair system operation,
the system keeps on working and fail-
ure is stored in order to be then detect-
ed by Alfa Romeo Authorized Services
at next inspection.GENERAL WARNINGS
When parking, take the utmost care to
obstacles that may be set above or un-
der the sensors. Objects set close to the
car, under certain circumstances are not
detected and could therefore cause dam-
ages to the car or be damaged.
Indications sent by the sensors can be
altered by dirt, snow or ice deposited on
the sensors or by ultrasound systems
(e.g.: truck pneumatic brakes or pneu-
matic hammers) set nearby the car.
TOWING TRAILERS
Sensors are reactivated automatically
when removing the trailer cable plug.
FAILURE INDICATIONS
The system control unit checks every
system component each time the key is
fitted into the ignition device. Sensors
and relevant electrical connections are
then constantly monitored during sys-
tem operation.
Sensor failure is indicated by message
+ symbol on the display (see section
“Warning lights and messages”).
Sensors operation is de-
activated automatically
when the trailer electric
cable plug is fitted into the car
tow hook socket.
