Learn how OnStar Emergency Services can help when you need assistance.

How It Works

Emergency Services are available to members who have Premium, Essentials, Safety & Security plans, or the OnStar Guardian app.


You can access Emergency Services in two ways:

  • Pushing the red SOS button in your vehicle or in the OnStar Guardian app
  • Calling 1-888-4ONSTAR


Both options connect you to an Advisor who can help you get assistance in cases of car crashes, downed power lines, medical emergencies, natural disasters and more. They can contact family members or emergency personnel.


The Good Samaritan feature also allows you to request help for others on the road in the case of an accident, abandoned vehicle or another emergency.
