If the vehicle is equipped with seat mounted side impact or roof rail mounted head curtain air bags, those will deploy in a side impact. If the vehicle is equipped with a roll over capable head curtain air bags, a roll over sensor will deploy the head curtain air bags in a roll over incident. The frontal air bags will not deploy in a side impact or roll over, unless there is also a front or front-corner impact of sufficient severity to trigger the frontal airbags. The airbags will not deploy in a rear impact.
