1. A lever for the temporary disengagement of a parking lock of a vehicle drive unit, wherein:
the lever comprises a fixing piece,
the fixing piece is designed for fitting the lever onto a parking lock shaft which serves to actuate the parking lock and extends at least partially inside the vehicle drive unit,
the lever is in the form of a dedicated hand lever with a gripping handle,
the gripping handle is designed to be directly gripped by a user and thereby to enable manual force to be applied, by the user, for the manual actuation of the lever,
the lever is designed such that when it is fitted onto the parking lock shaft:
when the gripping handle is moved from an engagement position to a disengagement position, by movement of the fixing piece, the parking lock shaft moves with the gripping handle, and, in the engagement position, the parking lock is engaged whereas in the disengagement position the parking lock is disengaged, and
in the disengagement position, by a further movement, the gripping handle is movable to a locking position in which the lever is blocked from a reverse movement out of the disengagement position.
