MY CHEST HIT THE STEERING WHEEL AND THEN THE AIR BAG DEPLOYED IMMEDIATELY ALL FUNCTIONS STOPPED WORKING.THE CAR FILLED WITH WHITE SMOKE FROM THE AIR BAG. MY WINDOWS WERE UP AND I COULD NOT ROLL THEM DOWN NOR STEER.I COULD NOT BREATH THE CAR WAS ROLLING IT STOPPED AT APPROX. 50 FT.WHEN I GOT OUT I WAS GASPING I HAD A WHITE SUBSTANCE ALL OVER ME IN MY NOSE. I'M VERY CONCERNED.
