Examples of the types of accidents in which it is possible that the driver’s/driver’s and front passenger’s SRS frontal airbag(s) will deploy.

Only the driver’s SRS frontal airbag or both driver’s and front passenger’s SRS frontal airbags may be activated when the vehicle sustains a hard impact in the undercarriage area from the road surface (such as when the vehicle plunges into a deep ditch, is severely impacted or knocked hard against an obstacle on the road such as a curb).
