After a little search, I found something. As other members said, I'm sure that the two front airbags will inflate in a severe accident if there is a person in the passenger's seat or not. It's written in the owner's manual. But there is an exception explained there too. An extract says this:«It is possible that, in a crash involving the front of yourvehicle, only one of the two frontal air bags in yourvehicle will deploy. This is rare, but it can happen in acrash just severe enough to make a frontal air baginflate.»This can be found in
