    Front Seat Belt Pretensioners

    The front seat belt pretensioners are designed to deploy in moderate or severe frontal, near frontal collisions.

    In addition, the pretensioners operate when a side collision or a rollover accident is detected. The pretensioners operate differently depending on what types of air bags are equipped. For more details about the seat belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria.
