An inflatable airbag system provides cushioning restraint of a vehicle occupant during an impact event of a vehicle. The airbag system can be configured to be mounted to a frontal region of a vehicle. The airbag system includes an inflatable airbag and a selectively actuatable vent that can be actuated in response to detection of an oblique impact event and/or a small overlap collision event. The selectively actuatable vent is actuated to open to provide additional venting and thus a lower pressure within the inflatable airbag. A lower pressure can reduce force and momentum on the vehicle occupant's head at an offset angled contact with the airbag. A lower pressure may also prevent the occupant from deflecting or rolling off of an airbag and colliding with other surfaces within the vehicle.
