Operation with trailer
The operation of the rear sensors is
automatically deactivated when the
trailer's electric cable plug is inserted
in the tow hook socket of the vehicle,
while the front sensors stay active
and can provide acoustic and visual
warnings. In this case, the LED on
the button (A) on the dashboard
fig. 219 stays off. The rear sensors are
automatically reactivated when the
trailer's cable plug is removed.
Fault indication
Parking sensor faults, if any, will be
indicated by a message on the display
(see description in the "Warning
lights and messages" chapter in the
"Knowing the instrument panel"
section).
Messages on the display
In case of system failure, a dedicated
message is shown on the display for
about 5 seconds.
If the display shows messages
requiring the front, side or rear sensor
cleaning, make sure that the outer
surface and the underside of the
bumper is free of dirt (e.g. snow, mud,
ice, etc.).
After performing this check, place the
ignition device in STOP position, then
turn it to position the MAR position and
check whether the messages are no
longer displayed. If messages are still
displayed, contact a Fiat Dealership.
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, thick
paint, on the surface of the sensor;
The sensor may detect a non-
existent obstacle (echo noise) due to
mechanical noises, for example when
washing the vehicle, in case of rain,
strong wind,;
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 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 ParkSense ® system, it is
recommended to remove the
removable tow hook ball assembly
and the respective attachment from
the vehicle 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 warning 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 is advisable
to contact a Fiat Dealership for
the ParkSense ® system update
operations because the tow hook could
be detected as an obstacle by the
central sensors;
the presence of adhesives on the
sensors. Therefore, take care not to
place stickers on the sensors;
the rear footrest (where provided)
must remain retracted to avoid false
signals from the ParkSense ® system;
opening the driver's door, passenger
door, side door and rear load
compartment door causes the side
detection system to be deactivated;
the side indication starts at the side
panel and does not take the size of the
exterior mirrors into account.
