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 a failure of the
automatic parking brake system, the
warning light ! on the instrument
panel and on the display illuminates.
Depending on the faults found, the
warning light is accompanied by the
following messages:
– Parking brake fault go to dealer
Slowly drive to the nearest Authorized
Maserati Dealer and remember that
the electric parking brake is not
functioning
– EPB is overheated
Turn off the engine for about 15
minutes and do not use the parking
brake. If the warning light comes on
again when restarting the engine,
slowly drive to the nearest Authorized
Maserati Dealer.

Follow the manual emergency
deactivation procedure in order to
release the parking brake.

wear limit: Contact your Authorized
Maserati Dealer to have the system

In the event of an EPB failure,

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 a
Authorized Maserati Dealer to resume
operation.
