I drive an electric vehicle. Do I have any special features in the app?

Yes. In addition to the standard capabilities of your vehicle's mobile app, drivers will be able to easily manage the capabilities of their electric vehicle with extended range including setting charge alerts, checking on current battery charge level and contacting a dedicated Advisor. This includes:

Remote commands: Your vehicle's mobile app will allow you to control a number of key vehicle functions and OnStar features from your mobile device. Drivers will be able to manage vehicle charging, read the state of battery charge, and review vehicle history data such as odometer readings, miles per gallon and miles driven in EV mode. In addition, you can perform traditional OnStar and key fob functionality such as door lock/unlock, horn and lights. An OnStar paid service plan is required for these functions.

Charge command status: You will receive a message on the application when a command has been successfully sent to the vehicle. If in view of the vehicle, the dash LED will be solid when charging, flash when the charge is on delay, and blink quickly if the battery is full and the vehicle is still plugged in.
