We have noticed this on two different CX-9s, when my wife, a tiny thing of 89 pounds, is in the passenger seat the Passenger Airbag Off light will at times light up and stay on while driving. Is there some kind of adjustment that needs to be made to make it stay on while she is in the seat and buckled up? When I am in the passenger seat, a much larger person, the light never goes on, just when she is there. It doesnt come on right away either, could be driving for some time before it pops up, but it seems to want to when she is in that seat.
