The parking brake button is located in the center console behind the gear lever switch (GWS). With the engine running or vehicle moving: The parking brake has a hydraulic effect on the disc brakes of the front and rear axle via the DSC. With the engine off and vehicle at a standstill: The parking brake employs Bowden cables and the electromechanical actuator unit to operate the drum brakes on the rear axle.
