Function requirements

 No overvoltage/undervoltage

 Circuit 15R ON or

 Circuit 15 ON

 The blinds are retracted.

Function

The sliding roof is opened by moving the roof system switch (N70s1) toward the rear of the vehicle to the actuation point. The overhead control panel control module (N70) reads the state of the switch and actuates the roof system motor (M12m1) for as long as the switch is activated, or until the panoramic sliding roof is completely open.

 Further actuation is only possible once the control module senses that the switch is in the neutral position (i.e. not activated for more than 1 second).

Function abort

If the overhead control panel control module (N70) detects a lock-up, the "open panoramic sliding roof" function is aborted.

When denormalized, the "open panoramic sliding roof" function is restricted. The motor can then be actuated for a maximum of 1 second. The switch must then be released and pressed again before another actuation can take place.
