WILL A SIDE OR REAR IMPACT OR ROLLOVER CAUSE THE AIR BAG TO DEPLOY?

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.
