Failure indicators

The system ECU checks all the
components every time reverse gear is
engaged.
In the event that the parking sensors
fail, the relative warning light
illuminates on the display,
accompanied by the message "Parking
help unavailable".
In the event of a failure signal, stop the
vehicle and turn the ignition key to
Stop. Then try cleaning the sensors or
moving the vehicle away from any
possible ultrasound sources (e.g.
pneumatic truck brakes or pneumatic
hammers) and rotate the ignition key
to the MAR position. This way, if the
cause of the operating fault has been
removed, the system will start
functioning again automatically and
the failure buzzer will stop.
If however, the failure beep continues,
contact the Maserati Service Network
to have the system checked.
During parking manoeuvres,
always be extremely careful
with obstacles that might be
located above or below the sensors. In
fact, in certain circumstances, objects
located near the rear of the vehicle are
not detected by the system and
therefore could damage the vehicle or
be damaged themselves.
The signals transmitted by the
sensors can also be altered by
damage to the sensors or by
dirt, snow or ice on the latter or even
by ultrasound systems (e.g. pneumatic
truck brakes or pneumatic hammers)
in the vicinity.
The driver is fully responsible
for parking and other
potentially dangerous
manoeuvres. During these
manoeuvres, always make sure there
are no people (especially children) or
animals in the manoeuvring area. The
parking sensors must be considered an
aid for the driver who, in any case,
must never take less care during
potentially dangerous manoeuvres,
even at low speeds.
