There are two inflatable curtains connected to the supplemental restraint system module (SRS). These connections are electrically separated from each other. The inflatable curtains are located in the roof between the A and C posts. The inflatable curtains have only one ignition component. The inflatable curtain protects the heads and upper bodies of any occupants in the event of a side on collision. The supplemental restraint system (SRS) module deploys the inflatable curtains individually, depending on the signals from the side impact sensors.

The inflatable curtain uses a pyrotechnic component in combination with a reservoir which stores a gas. On activation the pyrotechnic charge and mixes with the stored gas. The gas mixture is blown into the inflatable curtain which falls and covers the side windows and B post.

NOTE:

Never use an ohmmeter or similar tool to test airbags or seat belt tensioners. Disconnect airbags or seat belt tensioners before testing them. Failure to do so may result in accidental deployment. This could result in serious injury or death.
