SRS AIRBAGS The SRS (Supplemental Restraint System) airbags are designed to provide further protection for the driver and front passenger when added to the primary protection provided by the seat belts. In response to a severe frontal impact, the SRS airbags 128 work together with the seat belts to help prevent or reduce injury by inflating, in order to decrease the likelihood of the driver's or front passenger's head or chest directly hitting the steering wheel or dashboard. The passenger airbag is activated even with no passenger in the front seat. Be sure to wear your seat belt.
