1. A method for operating a motor vehicle that includes a prime mover (1), a drive output (2), and a parking lock (4), the parking lock (4) configured to block a shaft (3) coupled to the drive output (2) in an engaged condition and to release the shaft (3) in a disengaged condition, the method comprising:
coupling at least one coupling mass (6) to the shaft (3) when the shaft is blocked in order to increase a moment of inertia effective at the shaft (3); and
disengaging the parking lock (4) while the at least one coupling mass (6) is coupled to the shaft (3).
