The seat-occupancy detector is only used for the seat belt warning.
If the crash safety module triggers the airbags and the front passenger seat is unoccupied, the front
passenger's airbag, and the side airbag and head airbag on the front passenger side will not be triggered.
Whether or not the belt tensioner on the front passenger side is activated depends on the status signal of the
seat belt buckle switch (seat belt fastened or not fastened). The seat belt tensioner is also triggered if the seat
belt is inserted in the seat belt buckle switch (only in the case of head-on/rear-end impact).

The seat-occupancy detector is based on an evaluation of the surface pressure generated when the seat is
loaded.
