Passenger Airbag: Operation
WARNING: This page is about a different car, the 2005 Dodge Stratus and 2005 Chrysler Sebring. However, it is still accessible from the selected car via links, so may be relevant.
When supplied with the proper electrical signal from the ORC, the inflator produces gas and discharges it directly into the pillow. The airbag will deploy and the pillow will fully inflate.
