Actuation via control switch
^ Driver-side power window switch group (S20/1)
^ Front passenger power window switch (S21/2)
^ Left rear power window switch (S21/3)
^ Right rear power window switch (S21/4)

Actuation or activation via the driver-side power window switch group (S20/1) cannot be affected by the power window switch (S21/2, S21/3, S21/4).
An activation or an already active function from a power window switch (S21/2, S21/3 or S21/4) is terminated if a new request is received by the driver-side power window switch group (S20/1) for the corresponding window.
When the power window is activated again after locking up, the drive is switched off after approx. 0.6 s, when more than two Hall sensor edge changes from the corresponding power window motor (M10/3, M10/4, M10/5 or M10/6) are not recognized.

The windows can still be opened or closed for 5 min. after switching off circuit 15 or circuit 15R as long as the doors are not opened.The valid door status (door open or closed) is transmitted to the rear SAM control module with fuse and relay module (N10/2) by the left door contact switch (S17/3) and right door contact switch (S17/4), which then relays the information to the CAN class B bus.When a door is opened, all active power window functions are terminated.

Priority 1: Comfort closing and opening via soft top control button (S84/10) only on model (209.4)
Priority 2 : Driver-side power window switch group (S20/1)
Priority 3: Power window switch (S21/2, S21/3 and S21/4)
Priority 4: Comfort closing and opening via transmitter key (A8/1)
Priority 5: Comfort closing and opening via recirculated air switch (N22s2) with code (581a) Automatic air conditioning or recirculated air switch (N22/7s2) with code (581b) Comfort automatic air conditioning

A power window control command with higher priority is carried out if a power window function with lower priority is currently active.
A lower priority power window command cannot affect an active power window function of higher priority.
If the low-priority control command continues to exist after the function with higher priority is complete, then the power window control command is ignored. The park position of the lower priority power window control command must first be detected before the corresponding function is activated.
The first power window control command with a higher priority leads to discontinuation of the function, the second actuation to activation of the function.
