Wherever you are, we’re with you

Nothing is needed faster than help. With OnStar, you have it — in your vehicle, on your phone and at home. Our safety technology puts you in touch with Emergency Advisors at a moment’s notice. It’s our way of helping you be safe out there.

Emergency Services

If you spot an emergency situation on the road or have one of your own, push the red Emergency button to connect with an OnStar Emergency Advisor. They’ll direct First Responders to your location and offer critical assistance until help arrives.

Automatic Crash Response

If you’re in a crash, built-in vehicle sensors can automatically alert an OnStar Emergency Advisor who can contact help for you.

Stolen Vehicle Assistance

If your vehicle’s ever stolen, OnStar can work with law enforcement to help get it back quickly and safely.
