Abstract: Methods and systems are provided for controlling operation of an engine of a vehicle to supply power to a power box that in turn supplies power to loads external to the vehicle. In one example, a method comprises, via a controller, detecting that the vehicle is in a condition of reduced air exchange, and in response to a request to operate the engine to supply power to the power box, alerting the vehicle operator of the condition and discontinuing engine operation if a response to the alert is not received within a threshold duration. In this way, engine control strategy may account for the condition of reduced air exchange when the vehicle operator has acknowledged that the engine is operating under such conditions.
