Convenience closing function via recirculated air

When the recirculated air switch (N18s2, N22s2 or N22/7s2) is actuated and held down, the current window positions of the front power windows are stored and the windows are closed.

The request is transmitted to the left door control unit (N69/1), right door control unit (N69/2) and the power soft top control unit (N52) by the control and operating unit (N18, N22 or N22/7).

The left door control unit (N69/1) actuates the left front power window motor (M10/3). The right door control unit (N69/2) actuates the right front power window motor (M10/4).

The power soft top control unit (N52) actuates the left rear power window motor (M10/5) and the right rear power window motor (M10/6).

The stored window positions remain stored for 5 minutes after c. 15R or c. 15 OFF, if the doors are not opened and the vehicle is locked or unlocked via the transmitter key
