How does the SRS (Supplemental Restraint System) work?

The Supplemental Restraint System is a supplement to the seat belts. It is intended to protect the upper body of the riders in the front seats. To understand the Supplemental Restraint System.

  1. The SRS will deploy the airbags when the vehicle decelerates quicker than normal, indicating that something is wrong.

  2. The airbags will deploy to protect the upper body of the passengers where the seat belt could not.

  3. There may be a smelly, powdery residue after they deploy and this is normal.
