remote control, refer to page 27 or 29.
Anti-trapping mechanism
If the closing force rises beyond a pre-
defined threshold during closing, the sys-
tem will immediately stop moving the win-
dow prior to lowering it slightly.
Convertible: the back windows and
rear window are not equipped with an
anti-trapping mechanism.<
Despite the anti-trapping mechanism,
you should always inspect the front
side window's travel path prior to closing it,
as the safety feature might fail to detect
certain kinds of obstructions, such as very
thin objects, and the window would con-
tinue closing.
Pulling the switch beyond the resistance
point and holding it limits the response of
the anti-trapping mechanism. Under these
conditions, the window will respond to
forces beyond a defined threshold by only
opening a few inches/millimeters.
If you again pull the switch past the resis-
tance point and hold it in position within a
period of roughly 4 seconds, the anti-trap-
ping mechanism will be deactivated.<
Accessories in window area
After installing any accessory – such as a
clamp-on antenna for a portable phone –
within the window's travel range, you will
need to have the system reinitialized for
use under the new conditions. Please con-
tact your BMW center for assistance.

To prevent injuries, exercise care
when closing the glass roof and keep
it in your field of vision until it is shut.
When leaving the vehicle, always remove
the key and close the doors, as otherwise
children could operate the roof and injure
themselves etc.<

Anti-trapping mechanism
If the glass roof encounters resistance
when closing from the raised position, the
closing action is interrupted and the glass
roof opens.
If the sliding panel encounters resistance
when closing within approx. 8 in/20 cm, the
closing action is interrupted and the sliding
panel opens approx. 8 in/20 cm.
Despite the anti-trapping mechanism,
you should always inspect the roof's
travel range prior to closing it, as the safety
feature might fail to detect certain kinds of
obstructions, such as very thin objects, and
the roof would continue closing.
The anti-trapping mechanism for closing
the glass roof is deactivated if the switch is
pressed beyond the resistance point and
held there. The closing action is immedi-
ately interrupted when you release the
switch.<
Following interruptions in electrical
power supply
After disconnecting the battery, it can
occur that the glass roof does not move.
The system has to be initialized. Should
this occur, please have the roof initialized
at your BMW center.
