The air bag did not go off, I think that there is a relay that stops the airbag from going off when it is in 4lo. Let me show you what happened. When she called arb, she asked them if they had any trouble with similar setups, and they said only when the vehicle was in a wreck!! The guy said that they couldn't change the design because of all the areas the bumper was sold in, it wouldn't meet crash regulations in Australia.
