How Onstar Helps

Learn More at OnStar.com

If your air bag deploys, OnStar is designed to send a signal to a trained Advisor, who is there for you 24 hours a day, 7 days a week. OnStar's state-of-the-art technology can also call for help when you need it, even if airbags do not deploy. It's the only safety, security and communications system available across a wide range of vehicles that combines these important safety features.

Advanced Automatic Crash Notification (AACN)

See the full list

AACN enables an OnStar Advisor to provide emergency personnel with crash severity information even if air bags do not deploy (by using additional sensors to detect moderate-to-severe rear and side impacts.) AACN is available on select 2006 and newer GM vehicles.
