Visual Indications
The system indicates the presence of an
obstacle by displaying a single red arc in
the detected area, in relation to the
distance of the object and the position of
the vehicle.
If the obstacle is detected in the rear
central area, a single red arc will be
displayed as the obstacle approaches,
first constant, then flashing, in addition
to an acoustic signal.
If the obstacle is detected in the rear left
and/or right area, a single red flashing arc
will be shown in the corresponding area
on the display and the system will emit an
acoustic signal, either at frequent
intervals or constantly.
In general, the vehicle is closer to the
obstacle when a single red flashing arc is
shown on the display and the acoustic
signal becomes continuous.
If several obstacles are detected
simultaneously in the rear area, the
display will show all of them, regardless
of the area in which they were detected.
It is not possible to exit from the display
screen while the vehicle is in REVERSE.
Fault Indication
Parking sensor faults, if any, will be
indicated when REVERSE is engaged by a
message on the instrument cluster
display. Refer to "Warning Lights And
Messages On The Instrument Panel" in
"Getting To Know Your Instrument Panel"
for further information.
Messages On The Display
In case of system failure, a dedicated
message appears on the instrument
cluster for about five seconds.
Cleaning The Sensors: If the display
shows a message requiring the sensors
to be cleaned, make sure that the outer
surface and the underside of the rear
bumper is free of debris (e.g. snow, mud,
ice, etc.). Once these areas are clear,
cycle the ignition to the STOP position.
Then, return it to ON. If the message is
still displayed, contact your authorized
dealer.
Audio System Not Available: If the
display shows a message that the audio
system is not available, it means that the
acoustic signal will be emitted by the
instrument panel, and not through the
vehicles speakers.
Operation With A Trailer
The operation of the Park Sensors
System is automatically deactivated
when a trailer’s electrical connector is
plugged into the vehicle. The sensors are
automatically reactivated when the
electrical connector is removed.
Note: Some conditions may affect the
performance of the Park Sensors
System:
Reduced sensor sensitivity could be
due to the presence of ice, snow, mud, or
thick paint on the surface of the sensor.
The sensors may detect a false
obstacle (echo interference) due to
mechanical interference, for example
when washing the vehicle or in extreme
weather.
The signals sent by the sensors can
be altered by the presence of ultrasonic
systems (e.g. pneumatic brake systems
of trucks or pneumatic drills) near the
vehicle.
System performance can be
influenced by the position of the
sensors. For example, due to a change in
the ride setting (caused by wear to the
shock absorbers or suspension), by
changing tires, overloading the vehicle or
operations that require the vehicle to be
lowered.
Be sure not to place bumper stickers
or other adhesives over the sensors as
this will affect system performance.
The presence of a trailer hitch
without a trailer. This may interfere with
the operation of the parking sensors.
Before using the Park Sensors System,
it is recommended to remove or close
the trailer hitch assembly when the
vehicle is not being used for towing.
