Function requirements 

• No overvoltage or undervoltage
• Circuit 15R ON
• Circuit 15 ON
• Shutoff delay control activated
• The overhead control panel control unit (N70) detects the non-actuated state before the switch is actuated (no actuation within t= 1 s).

Shutoff delay control 

A shutoff delay control is implemented in the overhead control panel control unit (N70) for the drive of the roller sun blind and the panoramic sliding roof. The run-on time starts after c. 15R is "OFF" for 5 minutes, whereby the front doors should not be open and the vehicle should not be locked from the outside. The roller sun blind and the panoramic sliding roof can be operated during this time.

Function 

The "close panorama sliding roof" function is only available when the panorama sliding roof is in the normalized state. It is triggered by actuating the roof system switch (N70s1) to the pressure point toward the front of the vehicle while pressing the roof system switch(N70s1) manually. The overhead control panel control unit (N70) then actuates the panorama sliding roof motor (M12/6m1) which closes the panorama sliding roof. the is actuated as long as the switch is pressed or until the panoramic sliding roof is moved to its end position.

Interruption of sequence 

• The "close panoramic sliding roof" function is aborted if a lock-up of the panoramic sliding roof is detected.

The panoramic sliding roof is not equipped with an obstruction sensor.
