A suitable electrical system for a motor vehicle is provided, which system requires a voltage supply during a possible towing-away operation. A voltage-supply control device recognizes the provision of an external voltage supply, in particular by way of a towing vehicle for the motor vehicle, and controls the voltage supply in the motor vehicle in such a manner that only one or more subsystems of the entire electrical system of the motor vehicle are supplied with voltage.
