continuous sound is emitted. If there
are several obstacles, the closest one
is indicated.
FAULT INDICATIONS
Any parking sensor faults will be
indicated when reverse is engaged
by the warning light
(for versions with colour display)
in the instrument panel and by the
relevant message in the display (for
versions/markets, where provided).
OPERATION WITH A
TRAILER
(except the 1.0 FireFly Hybrid version)
The operation of the sensors is
automatically deactivated when the
trailer electric cable plug is inserted in
the tow hook socket of the car. The
sensors are automatically reactivated
when the trailer's cable plug is
removed.
GENERAL WARNINGS
When parking, take the utmost care
over obstacles that may be above
or under the sensor. Under certain
circumstances, objects close to the
vehicle are not detected by the system
and could therefore cause damage to
the car or be damaged themselves.
138
The following conditions may influence
the performance of the parking
assistance system:
the presence of ice, snow, mud or
multiple layers of paint on the surface
of the sensor may reduce its sensitivity
and the system performance;
or the icon
mechanical interference (e.g.
washing the car, rain, strong wind, hail)
may cause the sensor to detect a non-
existent obstacle ("echo interference");
the presence of ultrasonic systems
(e.g. pneumatic brake systems of
trucks or pneumatic drills) near the
vehicle could alter the signals sent to
the sensor;
the variation in sensor position,
caused by variation in ride (due to
suspension or shock absorber wear),
changing tyres, overloaded car, or
tuning that lowers the car, for example,
may affect parking sensor system
performance;
the presence of a tow hook without
trailer interferes with the correct
operation of the parking sensors. If a
fixed tow hook is installed, the sensors
cannot be used. If the customer installs
a removable tow hook, it should be
disconnected from the crossmember
whenever the trailer is not attached to
prevent the activation of the sensors.
the presence of adhesives on the
sensors. Therefore, take care not to
place stickers on the sensors.
WARNING
145) Parking and other dangerous
manoeuvres are, however, always the
driver's responsibility. While carrying out
these manoeuvres, always make sure that
no people (especially children) or animals
are in the area concerned. 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.
IMPORTANT
49) For correct operation of the system,
sensors must always be clean from mud,
dirt, snow or ice. Be careful not to scratch
or damage the sensors while cleaning
them. Avoid using dry, rough or hard
cloths. The sensors must be washed using
clean water, with the addition of vehicle
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.
50) 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.
