My sister and I were on our way to the store, full stop, my sister just got on the front passenger side, my sister noticed that the passenger airbag detection light on the dash remained in the "passenger air bag disengage" position even if my sister was sitting on the passenger seat. My car is not equipped with a manual passenger airbag disengage switch of some sort. So I assume that the light goes on or off only by detecting significant weight on the front passenger seat.
