A method for operating a pneumatic system of a vehicle is disclosed. The pneumatic system comprises an electronically and/or pneumatically controlled compressor which supplies compressed air during a normal mode and which is switched off or idles when not supplying compressed air. In the method, an ambient temperature (T_Umg) around the pneumatic system is continuously sensed and compared with a predefined target temperature (T_Ziel), a freezing risk is detected when the ambient temperature (T_Umg) reaches or drops below the target temperature (T_Ziel), and when a freezing risk has been detected, a cold mode is activated in which the compressor delivers compressed air also outside delivery phases of the normal mode, and additional compressed air is supplied to pneumatic system components that risk freezing. An additional ON time (ED_zus) of the compressor in the cold mode is variably controlled.
