Pinch protection system
If the glass roof encounters an obstruction dur-
ing closing from approximately the middle of
the opening in the roof, or during closing from
the tilted position, the closing movement is
interrupted and the glass roof is opened again
slightly.
Despite the pinch protection system
check and clear the roof's travel path prior
to closing it; otherwise, the safety system might
fail to detect certain kinds of obstructions, such
as very thin objects, and the roof would con-
tinue closing.<
Closing without pinch protection
If there is an external danger, press the switch
forward past the resistance point. The roof
closes without pinch protection.
Following interruptions in electrical
power supply
After a power failure, there is a possibility that
the glass roof can only be tilted. The system
must be initialized. BMW recommends having
this work performed by your BMW center.
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 trunk.
> Do not attach roof rack systems to the
retractable hardtop, and in particular do not
attach magnetic racks.

Opening and closing
> 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.
> If you open the hardtop while it is wet, e.g.
after driving in the rain, water may drip into
the trunk. If necessary, remove items from
the trunk beforehand to avoid water stains
or soiling.
Do not place any objects on the retract-
able hardtop or on the trunk lid; other-
wise, they could fall during movements of the
retractable hardtop and cause damage or injury.
Never move the retractable hardtop when the
rollover protection system is in the activated
position.
Driving when the hardtop is not fully opened or
closed may result in damage or injury.
Do not reach into the mechanism during the
opening or closing procedure. Keep children
away from the swiveling area of the retractable
hardtop.<
The retractable hardtop cannot be moved
at temperatures below
The retractable hardtop can only be
opened and closed when the vehicle is
stationary. To avoid causing damage, do not
drive off until the hardtop has stopped mov-
ing.<
Before opening and closing
>
Comply with the safety precautions
described above.
> Ensure that the trunk partition is folded
down and engaged on both sides, refer to
page 117; otherwise, it will not be possible
to open the retractable hardtop.
> Do not place any objects near or on the
trunk partition, refer to page 117.
