The acoustic indications are only
activated when the obstacle is on the
trajectory of the car and so there is a real
risk of collision.
The visual indications instead are also
provided to the driver, even when the
obstacle is not on the trajectory of the
car.
ACTIVATION / DEACTIVATION
The system can operate only after
driving a short distance and if the vehicle
speed is between 0 and 13 km/h (0 and 8
mph).
If the Park Assist system is active, the
Side Distance Warning system can be
disabled (and subsequently re-enabled)
using the "Settings" menu of the Alfa
Connect system. If the Park Assist
system is disabled, the Side Distance
Warning system will be automatically
disabled.
The activation conditions of the
Side Distance Warning system, the
characteristics of the acoustic signals
and the characteristics of the display
signals correspond to those of the 12-
sensor Park Assist system, as described
in the chapter "Park Assist system -
versions with 8 or 12 sensors".
OPERATION WITH A TRAILER
The system is automatically deactivated
when the trailer is plugged to the tow
hook socket of the car. Unplugging the
trailer cable will automatically reactivate
the system.
GENERAL WARNINGS
Some conditions may influence the
performance of the Side Distance
Warning system:
reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to the
presence of: ice, snow, mud, thick paint,
on the surface of the sensor
The sensor may detect a non-existent
obstacle (echo interference) due to
mechanical interference, for example
when washing the car, in rain (strong
wind), hail
the signals sent by the sensor can also
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems
of trucks or pneumatic drills) near the
vehicle
parking assistance system
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 car or carrying out
specific tuning operations that require
the car to be lowered
the presence of stickers on the
sensors can adversely affect the correct
operation of the system. Therefore, take
care not to place stickers on the sensors
IMPORTANT
67) The sensors must be clean of mud,
dirt, snow or ice in order for the system
to operate correctly. While cleaning the
sensors, make sure not to scratch or
damage them; avoid using dry, rough or hard
cloths. The sensors should be washed
using clean water with the addition of car
shampoo if necessary. When using special
washing equipment such as high pressure
jets or steam cleaning, clean the sensors
very quickly keeping the jet more than 10 cm
(4 inches) away.
68) Only have the bumper repainted or any
retouches to the paintwork in the area of
the sensors carried out by an Alfa Romeo
Dealership. Incorrect paint application could
affect the operation of the parking sensors.
