Abstract: A method for controlling a motor vehicle having at least one park lock. A drive train of the motor vehicle has a drive motor, wheel, and a transmission. An operating element actuates the park lock, which can assume a blocking position, in which the park lock blocks the drive train and/or a part of the drive train, and a release position. After actuation of the operating element, the park lock is switched from the release position into the blocking position (or vice versa). Here, the speed of the motor vehicle is determined. After actuation of the operating element and if the park lock assumes the release position beforehand, it is checked whether the speed is greater than a predefined first threshold value. If this check was successful, a first warning signal is produced; and the switching of the park lock into the blocking position is performed.
