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 turn the ignition key
back to position
MAR . This way, if the
cause of the operating malfunction
has been corrected, the system will
start functioning again automatically
and the failure buzzer will stop.
If the failure warning signal remains
on, contact the
Maserati Service
Network to have the system checked.
During parking manoeuvres,
always take the greatest
care to avoid 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.
The signals transmitted
by the sensors can also be
altered by damage to the
sensors or by dirt, snow or ice on
the sensors or even by ultrasound
systems (e.g., pneumatic truck
brakes or pneumatic hammers) in the
vicinity.
The driver always remains
responsible during parking
manoeuvres and in other
potentially dangerous situations.
When performing 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
always take care during potentially
dangerous manoeuvres, even at low
speeds.
