The electric parking brake replaces the traditional manual parking brake. It’s operated by means of two geared electric motors on the rear disc brakes. The mechanical components are designed to hold your parked car securely, even if the onboard electric power supply fails. Indicator lights on the instrument panel and on the dashboard switch, plus an operating sound, tell you when the parking brake has been activated.
The easy push-button operation offers more comfort and safety as well. For example, the dynamic automatic brake release makes it unnecessary to manually release the parking brake. All you have to do is drive off, and the brake releases automatically. And because the conventional parking brake lever is no longer necessary, you get more storage space between the front seats. Furthermore, the braking performance is constant at all times and reduces wear resistance.
The system is also employed in Hill Hold Control (HHC) and in the emergency braking function, greatly contributing to safety and driving comfort.
