About OnStar® Emergency Services

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

How it works

Emergency Services* are available to members who have OnStar One, OnStar One Super Cruise and OnStar 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 in cases of car crashes, downed power lines, medical emergencies, natural disasters and more. Even if you don’t know where you are, the Advisor will, and 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.

For your security, please don’t include personal info such as phone number, address or credit card details.
