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.
