SRS Air Bags

Supplemental Restraint System (SRS) Precautions

How the SRS Air Bags Work

Seat Belt Pretensioners

The pretensioners operate differently depending on what types of air bags are equipped. For more details about seat belt pretensioner operation, refer to the SRS Air Bag Deployment Criteria (Search).

Front

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 roll-over accident is detected.

Rear Outboard

The rear outboard 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 roll-over accident is detected.

  1. The front and side air bags for the front passenger and seat belt pretensioner and knee air bag are designed to deploy depending on the condition of the total seated weight on the front passenger seat.

  2. In a roll-over accident, the seat belt pretensioners and the curtain air bags deploy.

 


  • In a frontal offset collision, the equipped air bags and pretensioners may all deploy depending on the direction, angle, and rate of impact.

  • Some airbags and the pretensioners may not deploy depending on the level of the impact.
