Obstruction sensor
The excess force limiter (indirect obstruction sensor) is active while the windows are being closed.

Normalization
The power window must be normalized (upper mechanical window stop learned in) for the automatic raising and lowering function and the obstruction sensor.

PRE-SAFE (model 164.8)
The PRE-SAFE function is intended to prevent objects penetrating into the passenger cell when the vehicle skids as well as body or body parts of the vehicle occupants from swinging out of the vehicle.

The open side windows and the open tilting/sliding roof are closed leaving a gap of approx. 50 mm. This closing procedure can only be interrupted by actuating the driver power window and outside mirror adjustment switch group.

The power window must be normalized for the PRE-SAFE function.

The PRE-SAFE functions are described under foresighted vehicle occupant protection
