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. Driving off against the blocked brake pressure leads to another pressure increase and a Check Control message. Starting the engine leads to a switch from electromechanical to hydraulic parking brake engagement.
