Anti-trapping function
If the force of the power window motor exceeds a certain value while closing the window, the closing process stops immediately and the glass lowers slightly.
Always make sure there are no obstacles in the path of the windows, because in rare cases (for example, if a thin object is in the path of the glass) the anti-trapping function may not respond.
If the switch is held past the detent while closing the window, the protective function is limited. In this case, upon encountering an obstacle, the window opens only a few millimeters.
If the switch is pulled again past the detent within 4 seconds and then held in this position, the anti-trapping function is switched off.◄
