On-Demand Diagnostics - OnStar FMV Owner's Manual

On-Demand Diagnostics

If the "Check Engine" light comes on or if some other type of vehicle problem
occurs, an OnStar Advisor can tell you if the problem requires immediate
attention, or if it's something simple that can wait.
If it's a serious problem, the Advisor can:
• Contact Roadside Service or help find a dealership near your current location.
• Give directions to get to the nearest dealership.
• Call the dealership to schedule an appointment.
No matter where or when a concern occurs with the vehicle, have the peace of
mind knowing an OnStar Advisor, and hundreds of dealers, are ready to help.
Capabilities vary by model. Visit onstar.ca for details and system limitations.
