In an emergency, pushing the red Emergency button connects you to a specially trained OnStar Advisor who can notify first responders. Before help arrives, Advisors are certified to provide Emergency Medical Dispatch (EMD) assistance for situations such as shortness of breath, cuts, concussions, childbirth and other emergencies.
You can use Emergency Services* to help others on the road too. If you witness a crash or see a stranded vehicle or a downed power line, you can become a Good Samaritan by pushing the red Emergency button. A specially trained Advisor can use GPS technology and the information you provide to rush whatever assistance may be needed. Emergency services are only available to Members with a paid plan.
In severe weather conditions or a crisis, our Advisors provide a fast, knowledgeable resource if you need emergency assistance, help finding a route, or other services. They can also contact family members for you.
If you're in a crash, built-in sensors can automatically alert an OnStar Advisor and predict the likelihood of a serious injury. An Advisor is immediately connected into your vehicle to see if you need help, even if you can't ask for it. You don't have to do a thing.
It’s someone who pushes the red Emergency button to help someone else when they see an emergency on the road. An Advisor can use GPS technology and the information you provide to locate the emergency and contact the nearest emergency service provider.
No. Pushing the button connects you to a specially trained OnStar Advisor who is certified to provide EMD assistance. They will also contact emergency service providers like dialing 911 would. These EMD-certified OnStar Emergency Advisors can pinpoint your location and offer critical assistance until help arrives.
