Following interruptions in electrical
power supply
After a power failure, there is a possibility that
the glass roof can only be raised. The system
must be initialized. BMW recommends having
this work done by your BMW center.
Closing manually*
In the event of an electrical malfunction, you can
move the glass roof manually:
1. Unclip the front of the cover of the interior
lamps using the screwdriver from the
onboard vehicle tool kit, refer to page 233.
2. Insert the screwdriver into the openings on
each side to press the clips.
3. Remove the control unit.
4. Unplug the motor. Considerably less effort
will be required for manual operation.

into the opening provided. Move the glass
roof in the desired direction.

Convertible: retractable
hardtop
The retractable hardtop combines reliable
weather protection with simple and convenient
operation.
The following tips will enhance your driving
pleasure in your Convertible:
> It is advisable that you close the retractable
hardtop when you park the vehicle. Not only
does the closed hardtop protect the vehicle
interior against unanticipated weather dam-
age, it also offers theft protection. However,
even when the hardtop is closed, valuables
should only be stored in the locked cargo
area.
> Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.
>
Do not attach rack systems to the trunk lid,
and in particular do not attach magnetic
racks.
> When the retractable hardtop is operated,
the trunk lid swings back and up. Before
operating the retractable hardtop, ensure
that there is enough clearance, e.g. when
parked in front of a wall.
