How do you turn the passenger side airbag off in a 2010 Toyota Corolla?

Answer 1

According to the owner's manual, the passenger seat includes a detection system that takes into account how much weight is on the seat and if the seat belt is clicked. If the car determines there is no passenger in the seat, the air bag will not deploy during an accident (but there's no indicator light for that). If the car determines that there is a child in the seat the "airbag "off" indicator light should be illuminated and the air bag should not deploy during an accident. If the car determines the passenger is an adult, the air bag will deploy during an accident.

I am trying to find out what are the specific conditions the car uses to distinguish between a child and an adult. No details on that in the manual. Hope that helps.
