Deployment of the Airbags/Seat Belt Tensioners

Deployment Of The Airbags/Seat Belt Tensioners

The SRS (supplemental restraint system) system is extremely advanced and deploys the airbags and seat belt tensioners in the appropriate collision situation. Generally, it is not likely that all airbags and seat belt tensioners are deployed in the event of one accident. It is possible that only one airbag or seat belt tensioner deploys. This decision is taken by the supplemental restraint system module (SRS), based upon the forces of the collision.

1 stage deployment

The front airbags had 1-stage deployment in model year 1999-2000 cars.

When the Supplemental Restraint System Module (SRS) decides to deploy the airbags, deployment occurs at the same force.

2 stage deployment

The front airbags have 2-stage deployment in cars from model year 2001.

When the Supplemental Restraint System Module (SRS) deploys the front airbags, both stages are deployed. By varying the time between the two deployments, softer airbag deployment is achieved in the event of a low speed collision.
