PARKING SENSORS
(where provided)
Parking sensors inform the driver about
the presence of obstacles behind the car
(versions fitted with 4 rear sensors) or
behind and in front of the car (versions
fitted with 4 rear sensors and 4 front
sensors).
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 - and, only on cer-
tain versions, by an image on the dis-
play (see paragraph “Indications on the
display).

ACTIVATION
Versions with 4 sensors
Front sensors are automatically activat-
ed with electronic key fitted into the ig-
nition device when reverse gear is en-
gaged or when pressing the front ceil-
ing light button A-fig. 103 with speed
below 15 km/h.
Sensors are deactivated when exceed-
ing 18 km/h or, on certain versions by
pressing again the button if the speed is
lower than 15 km/h A-fig. 103. If
the system is off on versions with de-
activation button, the button led is off.Versions with 8 sensors
Front and rear sensors are automatical-
ly activated with electronic key fitted in-
to the ignition device when reverse gear
is engaged or when pressing the front
ceiling light buttonA-fig. 103with
speed below 15 km/h.
Sensors are deactivated by pressing
again button A-fig. 103if the speed
is lower than 15 km/h or when ex-
ceeding 18 km/h. If the system is off,
the button led is off.
When sensors are on, front and rear in-
dicators will sound warning signals as
soon as an obstacle is detected: as the
distance from the obstacle decreases,
the acoustic alarm becomes more fre-
quent.
When the distance between the car and
the obstacle is less than 30 cm, the
acoustic alarm becomes continuous. Ac-
cording to obstacle position (in front or
behind the car), the acoustic alarm will
be emitted by front or rear indicators.
In any case the system will indicate the
obstacle closest to the car.

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.
SENSORS
Obstacles are detected by 4 sensors lo-
cated in the front bumper (where pro-
vided)fig. 104and 4 sensors located
in the rear bumperfig. 105.
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.

BUZZER
The presence of any obstacle and its dis-
tance from the car is indicated by the
buzzers installed inside the passenger
compartment:
❒on versions with 4 rear sensors, the
rear buzzer will indicate the presence
of rear obstacles;
❒on versions with 8 sensors (4 front
sensors and 4 rear sensors) obstacles
are indicated by rear and front
buzzers. This feature gives the dri-
ver the direction (front/rear) of the
obstacle.

SENSOR DETECTION
RANGE
Sensors enable the system to monitor
the front part (versions with 8 sensors)
and the rear part of the car.
Actually their position covers the central
and side areas of the front and rear part
of the car.
An obstacle positioned at central area is
detected at a distance less than 0.9 m
(front) and 1.40 m (rear).
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.
INDICATIONS ON THE
DISPLAY (where provided)
On versions with 8 sensors, sensor acti-
vation is indicated on the “Reconfig-
urable multifunction display” (where pro-
vided) by screen fig.106; therefore ob-
stacle presence and distance is indicated
(in addition to buzzer) also on the in-
strument panel display.
In the event of several obstacles, the ob-
stacle closest to the car will be indicat-
ed.

DASHBOARD
AND
CONTROLS
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 warning
tand the corresponding
warning message 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 front or rear part, under certain cir-
cumstances are not detected and could
therefore cause damages 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
Rear sensors are reactivated automati-
cally 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 turning on
of warning light
t(where provided)
on the instrument panel (on certain ver-
sions together with the message on the
display) (see section “Warning lights
and messages”).
Rear sensors operation
is deactivated automat-
ically when the trailer
electric cable plug is fitted into
the car tow hook socket.
