A method is for operating a vehicle's electropneumatic brake system. The brake system includes a service brake system and a parking brake system. The parking brake system includes a spring brake cylinder. A control signal for maintaining a spring brake pressurization pressure, which pressurizes the spring brake cylinder, is provided via a control unit. The provision of the control signal is suspended in at least one of a fault event and/or in the event of an electrical failure and/or in a diagnostic event of the control unit and thus automatically ending the maintenance of the spring brake pressurization pressure to ventilate the spring brake cylinder and thus initiating a spring brake failsafe braking operation of the vehicle via the parking brake system. The ventilation of the spring brake pressurization pressure is performed by a service brake ventilation function of the service brake system.
