How Onstar Helps

Learn More at OnStar.com

With OnStar, you get the help you need even if you can't ask for it. In a crash, built-in vehicle sensors can automatically alert an OnStar Advisor who is immediately connected into your vehicle and can request emergency help to be sent to your exact location. OnStar Advisors are available 24 hours a day, 7 days a week and will stay on the line for as long as you need. OnStar is the only safety, security and communications system available across a wide range of GM vehicles that combines these important safety features.

Advanced Automatic Crash Notification (AACN)

See the full list

In a crash, built-in crash sensors around your vehicle automatically send an alert to OnStar. An Advisor is immediately connected into your vehicle to see if you're okay. Even if you're unable to respond, the Advisor knows your exact location through Global Positioning Satellite technology and requests emergency help be sent right away - no matter how remote the location. The Advisor can also relay critical crash information to emergency responders such as the severity and type of crash so responders are better equipped to treat you at the scene.
