A method for operating a vehicle having a vehicle drive train (1) and a vehicle brake (7) downshifting an automatic transmission (3) in a coasting condition, during which at least one friction-locking shift element is to be disengaged and one form-fit shift element is to be engaged. An output torque present at a driven end (4) is at least partially supported at a drive motor (2) at the point in time of a demand for the coasting downshift. The drive motor (2) is actuated before the implementation of the coasting downshift in order to reduce the portion of the output torque which is supportable at the drive motor (2), and a portion of the output torque is supported in the area of the vehicle brake (7) by an appropriate actuation of the vehicle brake (7).
