Fault signals
The system's ECU runs all the checks on
the components every time the reverse
gear is engaged.
A parking sensor system failure is
indicated by a continuous warning
signal from the buzzer when the
reverse gear is engaged.
In the event of a failure signal, stop the
vehicle and rotate the ignition key to
the STOP position. 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.
WARNING During parking maneuvers,
always take the utmost care over
obstacles that could be located above
or underneath 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.
WARNING 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.
However, the driver remains
responsible during parking
maneuvers and in other
potentially dangerous situations.
When these maneuvers are
performed, always make sure there
are no people (especially children) or
animals in the maneuvering area. The
parking sensors must be considered an
aid for the drivee who, in any case,
must never take less care during
potentially dangerous maneuvers,
even if they are carried out at low
speeds.
