A motor vehicle has an engine kill device that can automatically stop the engine. The vehicle has components for determining the engine may have been errantly left running, in which case the vehicle sends a notice to the user. The vehicle is capable of receiving a response from the user with instructions to leave the engine running. If no response is received, the vehicle can activate the engine kill device and stop the engine, or the vehicle can leave the engine running if a response is received from the user indicating the engine should remain running.
