Sensors are reactivated on removing
the trailer's electrical connection.
Before using the Park Assist system, it
is recommended to remove the tow
hook ball assembly and the relevant
attachment from the vehicle 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. In
addition, the sensors may provide a
false indication, interpreting the tow
hook ball assembly and the relevant
attachment as an obstacle in the area
behind the vehicle.
❒ 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;
WARNING
121) Parking and other potentially
dangerous manoeuvres are, however,
always the driver’s responsibility. When
performing these operations, always make
sure that there are no other people
(especially children) or animals on the route
you want to take. The parking sensors are
an aid for the driver, but the driver must
never allow their attention to lapse during
potentially dangerous manoeuvres, even
those executed at low speeds.
❒ 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 vehicle or fitting
specific trims 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. If a fixed tow hook is installed,
the parking sensors cannot operate
correctly. In the case of vehicles fitted
with removable tow hook, whether
as standard or installed after the vehicle
was purchased, it is advisable to
remove it whenever it is not used, to
prevent incorrect operation of the
sensors;
WARNING
42) The sensors must be clean of mud,
dirt, snow or ice in order for the system to
operate correctly. Be careful not to scratch
or damage the sensors while cleaning
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 away.
GENERAL WARNINGS
Some conditions may influence the
performance of the parking system:
❒ reduced sensor sensitivity and a
reduction in the parking assistance
system performance could be due to
the presence of: ice, snow, mud, paint,
etc. on the surface of the sensor;
❒ the presence of adhesives on the
sensors. Therefore, take care not to
place adhesives on the sensors.
43) Have interventions on the bumper in
the area of the sensors carried out only by
a Fiat Dealership. Interventions on the
bumper that are not carried out properly
may compromise the operation of the
parking sensors.
❒ the sensor may detect a non-existent
obstacle ("echo interference") due to
mechanical interference, for example
when washing the vehicle, in rain
(strong wind), hail;
