Function And Application
The seat airbag is a supplemental restraint system component mounted in the side of the driver’s seat. Its function is to inflate rapidly during a side-impact or certain rollover events to protect the torso and pelvis from intrusion and blunt-force trauma. Proper operation depends on intact wiring to the SRS system, a functioning squib connector, and correct seat position and mounting.
Fitment And Replacement Notes
This airbag is intended for vehicles listed above; compatibility is typically verified by matching OE part numbers and connector type. When replacing, confirm that the airbag shape, mounting points and electrical connector match the original unit. Seat airbags can differ between model years and trim levels (for example where seatbelt pretensioners or occupancy sensors are integrated), so inspect the existing assembly carefully before installation.

Most Common Causes Of Failure
Seat airbags usually fail or require replacement for a limited set of reasons: Deployment During A Collision, Connector Corrosion Or Damage From Moisture, Mechanical Damage From Seat Movement Or Improper Repair, Electrical Faults In The Squib Circuit, Or Damage From Previous Improper Disassembly. Airbags Do Not Typically Wear Out Like Mechanical Parts, but exposure to water or violent impact will compromise functionality.
