Function
The purpose of closing the side windows via PRE-SAFE is to prevent objects from entering the vehicle interior or to prevent occupant body parts (e.g., arms) from reaching out of the vehicle in the event of an accident.

The door control units (N69/1, N69/2, N69/3 and N69/4) receive the signal for automatic closing of the side windows over the Controller Area Network bus Class B (interior) (CAN-B) from the central gateway control unit (N93).

The side windows are closed until only a gap remains, in order to ensure that, in the event of a subsequent impact, any smoke particles generated by the pyrotechnical restraint systems can escape.

When the side windows are closed via PRE-SAFE, the obstruction sensor is active. If required, the closing process is reversed. Automatic closing of the side windows can be interrupted at any time by manually operating the power window switches (S20/1s1, S20/1s2, S20/1s3, S20/1s4, S21/2, S21/3 and S21/4) for each side window.

If automatic closing is activated via PRE-SAFE during an automatic lowering process, the automatic lowering process is aborted and closing is carried out via PRE-SAFE.

The side windows have to be manually moved back into the desired position after the PRE-SAFE situation has ended.
