Seatbelt sensor tells the system someone is there, the mat and seat sensor are an attempt to make sure the passenger is the right size to use the airbag. SO called smart airbags. Meh, I'd take them out if it wasn't such a freeking liability. Hate airbags. They are there to total cars not save lives. If your belt is properly on you dont even hit them. (In my experience....)
