Introduced on selected 2000 models, the Side Impact Air Bag System is designed to further enhance the effectiveness of the vehicle's inflatable restraint system. The Side Impact Air Bag System supplements the protection offered by the driver door, the front passenger door, and the vehicle structure. The Side Impact Air Bag system deploys an air bag from the side of the driver or front passenger seat. A side crash of sufficient force will deploy a side air bag.

The inflatable restraint Side Impact Sensor (SIS), the inflatable restraint front side impact module and the connecting wires make up the side impact deployable loop. The function of the side impact deployment loop is to supply current through the side impact inflator module, which will cause deployment of the side impact air bag. Deployment occurs when the SIS detects a side impact severe enough to warrant deployment.

The SIS contains a sensing device (accelerometer) that converts acceleration into an electrical (analog) signal. This signal is converted by a microprocessor in the SIS into acceleration and velocity data. This data is used by a sensing algorithm and compared to various predetermined boundary conditions. When the acceleration value exceeds the predetermined threshold, and the velocity boundary is crossed, the SIS signals the SDM to cause current to flow through the appropriate inflatable restraint front side impact module, deploying the front side impact air bag.
