Trailer Stabilization

NOTE: Activating this feature is only permitted for cars that come with a trailer hitch as factory installed equipment or where the retrofitted trailer hitch is similar to the factory installed one, additionally there are legal limitations for USA, Canada and Australia which do not permit the activation of this feature. Make sure the vehicle has been produced after 06/06/2005 (MY 2006+), earlier models may not support this feature - same applies for newer ones where you get an error when accessing the adaptation channel in question.
