performance can also be influenced by
the position of the sensors, for example
due to a change in the ride setting
(caused by wear to the shock absorbers,
suspension), or by changing tyres,
overloading the vehicle or carrying out
specific tuning operations that require
the vehicle to be lowered;
the presence of a tow hook without
trailer, which may interfere with the
correct operation of the parking sensors.
Before using the Park Sensors system, it
is recommended to remove the
removable tow hook ball assembly and
the relevant attachment from the car
when the latter is not used for towing
operations. Failure to comply with this
prescription may cause personal injuries
or damage to vehicles or obstacles since,
when the continuous acoustic signal is
emitted, the tow hook ball is already in a
position that is much closer to the
obstacle than the rear bumper. If you
wish to leave the tow hook fitted without
towing a trailer, it is advisable to contact
an Alfa Romeo Dealership for the Park
Sensors system update operations
because the tow hook could be detected
as an obstacle by the central sensors.

sensors. Therefore, take care not to place
stickers on the sensors.
VERSIONS WITH 8 SENSORS
The parking sensors, located in the front
(fig. 184 ) and rear (fig. 185 ) bumper,
detect the presence of any obstacles and
warn the driver through an acoustic
warning and, where provided, visual
indications on the instrument panel
display.

Engagement/disengagement
To disengage the system press button
fig. 183.
The LED in the button will light up or not
when the system switches from on to off
(and vice versa).
The LED on the button is off with the
system engaged, and on with the system
disengaged or in the case of a failure.
If the button is pressed with a system
failure, the LED flashes for about
5 seconds, then it stays on constantly.
System activation/deactivation
When the reverse gear is engaged and
the system is on, the front and rear
sensors are activated. If a different gear
is engaged, the rear sensors are
deactivated, while the front sensors
remain active until 9 mph (15 km/h) are
exceeded.
IMPORTANT In particular operating
conditions the system could start

detecting the obstacle only after the car
has moved slightly (a few centrimetres).
Acoustic signal
In the presence of an obstacle at the
front or the rear of the car, an acoustic
signal with variable frequency is
activated:
increases as the distance between the
vehicle and the obstacle decreases;
becomes continuous when the
distance between the car and the
obstacle is less than 12 in (30 cm) and
