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.
