A method is provided for operating a motor vehicle (100) having a headlight (1) with a projection module (2). The projection module (2) is moved into a projection position by a motor (3) to regulate a beam width of the headlight (1). The motor (3) is controlled to move the projection module (2) into the projection position and to reach a motor setpoint value. The motor setpoint value is stored in a non-volatile memory (4) of the headlight (1) and, when a voltage supply to the headlight (1) is activated following deactivation of the voltage supply, the projection module (2) is moved, starting from the stored motor setpoint value, into a leaving-home position so as to illuminate an environment adjacent to the motor vehicle (100). A headlight (1) and a motor vehicle (100) also are provided.
