Pinch protection system
If the closing force when closing the glass sun‐
roof exceeds a certain value, the closing move‐
ment is stopped, beginning at approximately
the middle of the opening in the roof, or from
the tilted position during closing.
The glass sunroof reopens slightly.
Danger of jamming even with pinch pro‐
tection
Despite the pinch protection system, check
that the glass sunroof's closing path is clear;
otherwise, the closing action may not be inter‐
rupted in certain extreme situations, such as
when thin objects are present.◀
Closing from the open position
without pinch protection
E. g. if there is an external danger, proceed as
follows:1.Press the reel forward beyond the resist‐
ance point and hold.
The pinch protection is limited and the
glass sunroof reopens slightly if the closing
force exceeds a certain margin.2.Press the reel forward again beyond the re‐
sistance point and hold until the glass sun‐
roof closes without jam protection. Make
sure that the closing area is clear.
Closing from the raised position
without pinch protection
If there is an external danger, push the reel for‐
ward past the resistance point and hold it.
The glass sunroof closes without jam protec‐
tion.
Initializing after a power failure After a power failure during the opening or
closing process, the glass sunroof can only be
operated to a limited extent.
Initializing the system
The system can be initialized when the vehicle
is stationary and the engine is running.
