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.
SENSORS
The sensors are located in the rear
bumper fig. 123 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 warning.
GENERAL WARNINGS
When parking, take the utmost care
over obstacles that may be above or
under the sensor.
Objects close to the car are not
detected under certain circumstances
and could therefore cause damage to
the car or be damaged.
ACOUSTIC WARNING
When reverse gear is engaged and
there is an obstacle behind the car an
acoustic warning is activated and the
warning varies as the distance of the
obstacle from the bumper varies.
The frequency of the acoustic warning:
increases as the distance between
car and obstacle decreases
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;
mechanical interference (e.g.

becomes continuous when the
washing the vehicle, 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,
ACTIVATION/
DEACTIVATION
distance between the car and the
obstacle is less than 30 cm and stops
immediately if the distance increases
is constant if the distance between
the car and the obstacle is unchanged.
The sensors are automatically activated
when reverse gear is engaged. The
acoustic warning becomes more
frequent as the obstacle behind the car
gets closer.
Detection distances
If several obstacles are detected by
the sensors, only the nearest one is
considered.
OPERATION WITH A
TRAILER
