Your vehicle is equipped with an electro-mechanical parking brake. The parking brake replaces the conventional handbrake, and is mainly intended to prevent the vehicle from rolling away accidentally.

However, the electro-mechanical parking brake also offers a number of convenience and safety features in addition to the functions of a normal handbrake.

When driving away

  • • The parking brake auto release function releases the parking brake automatically when you wish to start moving, “Driving away from a standstill”.
  • • When driving away on a gradient, the parking brake auto release function prevents the vehicle from rolling back unintentionally. The braking force of the parking brake is only released when there is enough power at the wheels to make the vehicle move in the desired direction.

Emergency braking function

An emergency braking function enables you to stop the vehicle even if the conventional foot brake should fail to work, “Emergency braking function”.

  • • The parking brake runs an automatic test cycle at regular intervals when the vehicle is parked. This may also cause a slight noise, which is normal.
