Turning the front and rear sensors
on/off (where provided)
The system can be turned off using the
"Driver Assistance" menu and then select
"Comfort" on the Connect system.
When the ignition device is set to ON
the Park Sensors system keeps the
last state when the engine was stopped
(activated or deactivated) in its memory.
If the button fig. 183 is pressed with a
system failure, the LED flashes for about
5 seconds, then it stays on constantly.

System activation/deactivation
For 4-sensor versions: the system, when
engaged, is automatically activated by
engaging the reverse gear, while it is
deactivated by engaging another gear.
For 8-sensor versions: when the reverse
gear is engaged and the system is on, the
front and rear sensors are activated.
If a different gear is engaged, the rear
sensors are deactivated, while the front
07176V0001EM
sensors remain active until 9 mph (15
km/h) are exceeded.
WARNING In particular operating
conditions the system could start
detecting the obstacle only after the car
has moved slightly (a few centimetres).
Acoustic warning
When reverse gear is engaged and an
obstacle is encountered at the rear
(for versions with 4 or 8 sensors) or
at the front (only for versions with 8
sensors), an acoustic signal with variable
frequency is activated that:
increases as the distance between the
car and the obstacle decreases;
becomes continuous when the
distance between the car and the
obstacle is less than 12 in (30 cm) and
stops if the distance increases;
is constant if the distance between the
car and the obstacle is unchanged.
For 4-sensor versions: If several
obstacles are detected by the sensors,
07176V0002EM
only the nearest one is considered. The
acoustic signal is not activated if the
lever is positioned in position P (Park) or
N (Neutral).
For 8-sensor versions:iIf the sensors
detect several front and rear obstacles,
the acoustic signal concerning the
closest obstacle is emitted, or an
intermittent signal if the obstacles are at
the same distance.
When the system emits an acoustic
signal, the volume of the Connect
system, if activated, is automatically
lowered.
Warning on display
The Park Sensors system signals are
shown along with an acoustic indication
only if the function was enabled on the
Connect system. To access the function,
on the main menu select the following
items in sequence: "Settings", "Driver
Assistance", "Parking sensors", "Mode"
and "Sound and Display".
The system indicates the presence of
an obstacle by displaying a single arc in
one of the possible areas, in accordance
with the distance of the object and the
position in relation to the car.
If the obstacle is detected in the front
or rear central area (excluding 4-sensor
versions), a single arc will be displayed as
the obstacle approaches, first constant,
then flashing, in addition to an acoustic
signal.
