OnStar Guardian app highlights

Roadside Assistance*

When experiencing roadside trouble, you and your loved one can use the Guardian app to get help for any car or motorcycle.

A person's hand reaches for a rose-gold smartphone resting on a brown leather handbag, displaying an OnStar notification that reads "OnStar Emergency Advisor has detected a crash."

Mobile Crash Response

In a crash, the smartphone’s sensors can alert an OnStar Advisor to check in with you and help send First Responders to your location.

A first responder, wearing a uniform and carrying a medical bag, attends to a damaged dark SUV on the side of a road, with an ambulance with flashing lights visible just behind the vehicle.

Safety Services

We’re here for you and your family 24/7 — just push the red Emergency button in the app. Or enable Siri^®* or Google Assistant* with your voice to get help.

A hand holds a smartphone displaying a map application with the user's location near a lake, showing options to "Roadside," "Call OnStar," and "Call SOS," with a bicycle blurred in the background, suggesting outdoor activity.

Location Services*

For less worrying as you get going, use your smartphone to see your family on a live map, share and save locations, and set arrival and departure notifications.
