The invention relates to a method for controlling an actuating system of an automated clutch in a motor vehicle. The control of the actuating system is accomplished by means of a control unit. The actuating system comprises a piston, a cylinder, and a sealing ring arranged on the piston or on the cylinder in a circumferential direction. The purpose of the method is to position the piston in the cylinder in an axial direction. The cylinder and/or the piston has an opening in the respective lateral surface of the cylinder and/or of the piston, over which opening the sealing ring can travel during a piston movement in the axial direction in both directions. The method is characterised in that, during a specified standstill situation of the vehicle, the piston is moved to a parking position in the cylinder, which parking position is selected in the cylinder in such a way that the sealing ring is positioned without overlap with the opening.
