A method for operating a pressure control system having a multistage compressor includes providing, by the multistage compressor, a pressure medium that has been compressed multiple times in order to fill a pressure medium reservoir or pressure medium chambers of the pressure control system. The providing the pressure medium involves providing, by a first compression stage, a precompressed pressure medium and additionally compressing, via a second compression stage, the precompressed pressure medium, and/or introducing an already compressed charge pressure medium into an intermediate volume between the first compression stage and the second compression stage of the multistage compressor and further compressing, by the second compression stage, the charge pressure medium. The charge pressure medium simultaneously passes, via a control line, to a control input of a shut-off valve that interacts with the first compression stage, such that a charge pressure of the charge pressure medium predefines a control pressure.
