The Supplemental Inflatable Restraint (SIR) system supplements the protection that the following restraint systems provide:

    • The driver and the front passenger seat belts (2)
    • The air bag (1)
        The air bag provides protection from the following locations:
       - The front center of the steering wheel
       - The top of the right side instrument panel

The air bag (1) deploys when the vehicle is involved in a frontal crash of sufficient force up to 30 degrees off the centerline of the vehicle. In order to further absorb the crash energy a knee bolster (3) is located beneath the instrument panel for both the driver and the passenger. The steering column is collapsible. Refer to Restraints.
