Automatic Crash Response

The moment a crash is detected, a specially-trained Emergency Advisor is connected to your vehicle. If you request help, or can't answer, emergency responders are sent to your precise GPS location. Advisors monitor the OnStar network 24 hours a day, so there's always someone to help when you need it most.

Your vehicle also transmits important crash data to OnStar, including direction and number of impacts, rollover status, and a maximum velocity at impact. This measures the impact, and helps first responders gauge severity. An Advisor shares this potentially life-saving information with responders before they even arrive.

After a crash, an invisible countdown begins. Emergency professionals call it "the Golden Hour:" it's the best time to minimize injury and maximize outcomes. Automatic Crash Response helps medical workers get to you faster, armed with information about your emergency.
