1. A method of operating a motor vehicle with a motor, a driving transmission having at least one shifting element, a power take-off and a power take-off clutch by which the power take-off is coupleable to the driving transmission, the method comprising at least the following steps:
detecting a request to couple the power take-off;
checking whether respective boundary conditions for coupling the power take-off are fulfilled;
when the respective boundary conditions are fulfilled, building-up a system pressure sufficient for actuating the power take-off clutch;
checking whether a system pressure sufficient for actuating the power take-off clutch has been built up;
when sufficient system pressure has been built up, producing a confirmation signal that actuation of the power take-off clutch is permitted; and
modifying a driving transmission control unit in reaction to the confirmation signal, in order to actuate the at least one shifting element of the driving transmission with a higher actuation pressure than with an unmodified driving transmission control unit.
