WARNING: In certain conditions when
the battery voltage is low, the electric
parking brake system may temporarily
be deactivated for safety reasons.
Therefore, typically upon starting the
engine, when the battery voltage drops,
the message PARK OFF may temporarily
be displayed, indicating that automatic
operation is temporarily disabled.
WARNING: In case of performance starts,
check that the electric parking brake is
deactivated.

Malfunction indication

In the event of electric parking brake
system failures, the warning light
on the display will come on.
Depending on the message displayed,
it signals the following failures of the
EPB system:
– Parking brake failure.
If the message warning you to go to
the nearest Service Centre of the
Maserati Service Network is
displayed, drive slowly and
remember that the electric parking
brake device is not functioning.
– Excessive temperature.
If the vehicle has been stationary
(key to STOP) for about 15 minutes
without using the parking brake,
and the warning light illuminates
again after restarting the engine,
slowly drive to the nearest Service
Centre of the Maserati Service
Network.
If the parking brake failure is
accompanied by the message
"Mechanical release only", follow
!
the manual emergency deactivation
procedure in order to release the
parking brake.
– Parking brake system overhaul.
The EPB system requires
maintenance, therefore contact a
Service Centre of the Maserati
Service Network to have the system
corrected.
In the event of an EPB failure,
take your vehicle to the
nearest Maserati Service
Network Centre as soon as possible.

Emergency disengagement

In the event that the electric parking
brake locks with a total system failure,
you need to manually release the
parking brake using the special tool
provided in the toolkit.
To do this, proceed as follows:
– Remove the panel that covers the
spare wheel compartment in the
luggage compartment.
– Remove the cap on the right-hand side
of the EPB ECU.
– Insert the special tool in its seat.
– Turn the handle clockwise until
release.
– Remove the tool from its seat and close
it with the cap.
After each manual emergency
release, the electric parking
brake system remains
inefficient and must be repaired by the
Maserati Service Network to resume
operation.
