Ford Expedition is equipped with six standard airbags, strategically placed to help protect you and your passengers.* There are dual-stage front seat airbags, front seat-mounted side airbags, and side curtain airbags (part of the Safety Canopy® System)* that deploy from the headliner on both sides of the vehicle. A rollover sensor directs side curtain and side airbag deployment in the event of a rollover or certain side-impact collisions. The airbag inflators for the side curtain are on the rail rail between the C-pillar and the D-pillar.
