Welcome to the forum.
Maybe you will find an enthusiast here, who will know the answer, but why not call your local MB dealer or 800 FOR MERC, assuming you are in USA.
This forum is for DIY who work on their cars and new cars need to age few years before the topics on them will become popular on this forum.
Good luck on your shopping.
