If the soft top has jammed
in an intermediate position,
because its movement was
intentionally stopped or due to a
failure of the hydraulic and electric
systems, after remaining in this
position for approx. 10 minutes
the hydraulic circuit loses pressure,
thereby allowing the soft top and
the relative housing cover (driven
by their weight) to reach a resting
position. Therefore, take the greatest
care to avoid that people or objects
in the vicinity may interfere with
4
the soft top travel during this time.
In this case, do not operate the soft
top using the automatic control until
the system has reached a steadily
balanced position (fully open or fully
closed).
WARNING: The soft top failure
temporarily disables, for approx.
10 minutes, the power windows'
operation. After this time, the
power windows will resume normal
functioning.

Soft top manual operation in
the event of an emergency
Manual operation of the soft
top for emergency closing
requires the presence of two
persons in order to prevent personal
injury or damage to the car.
When moving the soft top
by hand, take the greatest
care as its movable parts
could squeeze or trap objects or parts
of your body.
In case of need, the soft top may be
opened and closed manually.
WARNING: The emergency procedure
described below must be used to close
the soft top if it is not possible for
you to contact the Maserati Service
Network immediately and you cannot
keep the soft top open.
WARNING: If the failure occurs while
opening the soft top, do not attempt
to open it manually: contact the
Maserati Service Network.
If the failure occurs when the opening
procedure is already in progress,
do not attempt to complete the
procedure - close back the soft top
manually according to the following
instructions. After depressurizing
the hydraulic circuit by turning the
key to STOP, perform the emergency
procedure starting from the point at
which the opening stage jammed.
After depressurizing the
system, the soft top will
move freely. Therefore, if it
is not in a balanced position, it will
close or open as a consequence of
its weight. Take the greatest care to
avoid being squeezed or trapped by
its levers and mechanisms.
WARNING: In the case of a failure
of the hydraulic operation system,
contact the Maserati Service Network
directly. If this is not possible, close
the soft top manually and then
contact the Maserati Service Network
to have the system checked.
