WARNING:

Never use an ohmmeter or similar tool to test airbags, inflatable curtains, adaptive belt force limiters, adaptive steering column or belt tensioners. Disconnect airbags, inflatable curtains, adaptive seat belt limiters, adaptive steering column or belt tensioners before testing them. Failure to do so may result in accidental deployment, which in turn could result in serious injury or death.

There are two side airbags connected to the supplemental restraint system module (SRS). Their connectors are electrically separated from each other. The side airbags are on the outer edge of the front seat backrests, underneath the upholstery. The side airbags are only deployed on the side nearest the point of the impact. Their task is to protect the hips, chest and upper body in the event of a side-on collision.

The side airbags together with the inflatable curtains and other safety systems can help to protect the driver and front passenger in the event of a side-on collision.

The side airbag uses a pyrotechnic component in combination with a reservoir which stores a gas. In the event of deployment, the pyrotechnic charge combusts and mixes with the stored gas. The gas mixture inflates the airbag.
