The invention relates to a circuit for selectively actuating drive elements (), which are operated on direct current, in a motor vehicle by means of half-bridges (). According to the invention, the circuit is designed for selectively actuating eight drive elements () for locking and, respectively, unlocking four doors of the motor vehicle from the outside and/or from the inside. The circuit contains nine half-bridges (), wherein the outputs of eight of the nine half-bridges () are each connected to a first pole of one of the eight drive elements () and the output of the ninth half-bridge () is connected to all second poles of the eight drive elements ().

Circuit for selectively actuating DC motors in a motor vehicle

A method for operating a motor vehicle having one or more electrical systems/devices, wherein the systems/devices are operable in at least two different modes. In a normal mode, a vehicle key is required for activation of at least one of the electrical devices. After enabling of a presentation mode, activation of the at least one device is possible without use of the vehicle key. The presentation mode is optimized for use in a dealership, where certain electrical/electronic functions of the vehicle should be available for use by a potential buyer without the requirements of a dealership employee being present with the vehicle key.
