It says off until someone or something is on the seat, I think it is around 50 pounds or so. There is a pressure switch that gets activated. If someone is on the seat and it still says off, take it to the dealer as you are probably still under warranty.I have a 2006 corolla xrs..My passenger airbag light says its off. Can it be that I just have to reset it? If so how can I do that. Or can it be that I have to replace the sensor?
