Seat occupied recognition sensor
If the front passenger seat is occupied by a person, the pressure load of the seat area increases. This changes the resistance of the force sensing resistors in the sensor mat. If the pressure on the seat surface exceeds a defined value, the electronic analysis system detects that the front passenger seat is occupied by a person and transmits an "occupied" signal to the restraint systems control unit (N2/7). The seat occupation status is continuously monitored. After the load on the front passenger seat has been removed, the occupied signal is retained for approximately 2 min. The signal is retained to prevent immediate shutoff of the safety devices if the load on the front passenger seat is removed for a short period.

Automatic child seat recognition
The functionality of the automatic child seat recognition is only given where a Mercedes-Benz approved and control-unit coded child seat are used. This child seat must be equipped with 2 transponders, which are located in its base on the left and right. Where a child seat is in its position, the signals from the transponders located in the child seat, which the electronic analysis system sends via the transmitting antennas, are changed. These signals are picked up by the respective receiving antennas in the sensor mat and forwarded to the electronic analysis system. The front passenger seat occupied and child seat recognition sensor (B48) evaluates these signals and notifies the restraint systems control unit (N2/7) about the following statuses:
^ Child seat present/not present
^ Child seat installed facing/facing away from direction of travel
