This Shouldn't make a difference, I'd imagine your air bags are fully functional. I think that is just a warning that the seat (or it thinks is not) isn't mounted right and air bag won't protect you as well, but this is a newer model so I'm not sure. But if it does worry you I'd take it in to a dealer.
