WARNING: This page is about a different car, the 2018 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
The side airbag is a single-stage airbag which is designed to provide protection for the seat occupant's torso. It deploys upon receipt of current flow and is attached to the outboard side of each front seat. It is used in conjunction with the side air curtain.
