Parking sensors (optional)
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 your
Authorized Maserati
Dealer to have the system checked.
WARNING: During parking maneuvers,
always take the utmost care with
obstacles that could be located above
or underneath the sensors. In fact, in
certain circumstances, objects located
near the rear of the vehicle may not be
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.
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 are only a
supplementary aid for the driver.
