OnStar®
For vehicles with an active OnStar subscription, OnStar uses several innovative technologies and live Advisors to provide a wide range of safety, security, navigation, diagnostics, and calling services.
Automatic Crash Response
In a crash, built-in sensors automatically alert an OnStar Advisor who is immediately connected to the vehicle to see if you need help.
