Function 

The power window feature allows the front and rear side windows to be opened and closed.

There are two actuation possibilities:

• Manual window up/down feature
• One-touch up/down feature

The short stroke function  ensures that the doors and the frameless side windows can be opened and closed without malfunction.

With the convenience feature  it is possible to open or close all four side windows with the remote control key.

Soft start/soft stop 

Actuation of the power window motors starts and stops with reduced power. This control module function serves for reducing power window mechanical wear. When the motor actuation starts the control module power is approx. 15 %. It is linearly increased to 100 %. The power is reduced from 100 % to 70 % starting at an inside opening of approx. 30 mm before reaching the upper or lower stop.

The power is increased/decreased over a period of t = 250 ms.
