OPERATION WITH A
TRAILER
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;
PARKING SENSORS
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.

SENSORS
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 sensors are located in the rear
bumper fig. 89 and their function is to
detect the presence of any obstacles
near the rear part of the car and inform
the driver, through an intermittent
acoustic signal.
IMPORTANT NOTES
When parking, take the utmost care
over obstacles that may be above
or under the sensor.
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, this must
always be disconnected from
Objects close to the car are not
detected under certain circumstances
and could therefore cause damage
to the car or be damaged.
The following conditions may influence
the performance of the parking
assistance system:
the crossmember whenever the trailer
is not attached to prevent the activation
of the sensors.
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;

WARNING
ACTIVATION/
DEACTIVATION
mechanical interference (e.g.
washing the car, rain, strong wind, hail)
may cause the sensor to detect a
non-existent obstacle ("echo
interference");
127) Parking manoeuvres, however, are
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 used
to assist the driver, who must never allow
his attention to lapse during potentially
dangerous manoeuvres, even those
executed at low speeds.
The sensors are automatically activated
when reverse gear is engaged. The
acoustic warning becomes more
frequent as the obstacle behind the car
gets closer.
