SOS Post-Crash Alert System™

The system automatically flashes the turn signal lamps and sounds the horn three times at four second intervals in the event of a serious impact that deploys an airbag (front, side, side curtain [if equipped] or Safety Canopy [if equipped]) or the safety belt pretensioners.
The system can be turned off when any one of the following actions are taken by the driver or any other person:
• pressing the hazard control button,
• or pressing the panic button on the remote entry transmitter.
The feature will continue to operate until the vehicle runs out of power.
