Passenger Airbag Canister Vent
WARNING: This page is about a different car, the 2017 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
The passenger airbag canister vent is a deployable device that is part of the passenger airbag. Canister venting controls the inflation rate of the passenger airbag and the escape rate of gases from the vent. The canister vent cannot be serviced separately from the passenger airbag.
