Side Air Bags Front And Rear (Thorax)

The side airbags are mounted on the inner door frame of the front and rear doors. Deployment of the side airbags is dependent on the triggering thresholds programmed in the MRS III control module and based on the inputs from the satellite sensors and internal crash sensors.

The side airbags use the same cold gas inflation method as the driver's and passenger's front bags.

Rear side airbags arrive de-activated from the factory and can only be enabled upon written customer request. This is designed to prevent a risk of injury to small children who may be sitting out of position and too close to an airbag in the back seat.
