The concept

The parking brake is used to prevent the vehicle from rolling when it is parked.

  • Engine switched off: the parking brake acts on the rear wheels.
  • Engine running: the parking brake acts on the disc brakes of the front and rear wheels via the hydraulic brake system.

The parking brake can be set manually or automatically:

  • Manual: by pulling and pushing the switch.
  • Automatic: by activating Automatic Hold.
