Systems and methods of electrically heating catalyst (EHC) driver notification are provided. With the goal of increasing driver cooperation in reducing emissions, EHC driver notification systems notify the driver when the EHC is in an inefficient operation state. This notification is provided to the driver so that the driver may consciously operate the vehicle in a fashion that reduces emissions while the EHC is in the inefficient operation state. EHC driver notifications systems may also restrict operation of the vehicle when the EHC is in an inefficient operation state. However, for safety reasons, these systems provide the driver a function to bypass the restriction as needed.
