OnStar Mobile App

With an iPhone® or Android™-based mobile device, an OnStar mobile app can be downloaded. The vehicle can be remote started, if equipped, or the doors can be unlocked from anywhere there is cell phone service. It can also check the fuel level, tire pressure, and oil life.

It can connect to an OnStar Advisor anytime. For OnStar mobile app compatibility or further information, see www.onstar.com.
