Parking sensors

To assist the driver during parking
manoeuvres, the vehicle may come
equipped with four sensors housed in
the rear bumper and four sensors in
the front bumper (optionals in the
latter case).

During parking manoeuvres, the
parking sensors provide the driver with
information on the distance between
obstacles found behind and in front of
the vehicle. The information about the
obstacle distance is given to the driver
by means of a acoustic and visual
signals. The acoustic signals generated
by the system add to the driver's field
of vision, allowing him to avoid hitting
any obstacles during manoeuvres.
However, the driver remains
responsible during parking
manoeuvres and in other
potentially dangerous situations. The
system has actually been designed
only as a supplementary aid during
parking manoeuvres, since it allows
the driver to detect obstacles outside
his field of vision.
The front and rear parking sensors are
automatically activated when the key
is turned to MAR, when reversing.

Parking sensors
If the vehicle is also equipped with
front sensors, these may be activated
by pressing button A; When the front
sensors are active, the button
illuminates with an amber colour. To
deactivate the front sensors, press
button A once again. When reverse
gear is disengaged, all the sensors
remain active. The rear sensors remain
active for about 10 seconds or until a
speed of approx. 6 mph (10 Km/h) is
exceeded. The front sensors remain
active until a speed of about 6 mph
(10 Km/h) is exceeded.
When the rear or front sensors are
activated, an acoustic signal (beep)
warns the driver that the system is
active.
When the sensors are activated, the
system begins to beep as soon as an
obstacle is detected, and the tone
A
frequency increases as the vehicle
approaches the obstacle.
The acoustic signals are emitted by two
buzzers, one under the dashboard (if
the vehicle is equipped with front
sensors) and one in proximity of the
luggage shelf (if the vehicle is
equipped with rear sensors).
When the obstacle is located at a
distance of less than 14 in (35 cm) from
the bumper, the beep is continuous.
The warning beep stops immediately
if the distance between the vehicle and
the obstacle increases.
The tone cycle is constant if the
distance measured by the central
sensors remains unaltered, while if this
occurs with the lateral sensors, the
signal stops after approximately 7
seconds, to prevent for example
continuous beeps in the event of
manoeuvres alongside walls.
