Display on unlock

Had a question on the display on the speedometer that shows the km. When I unlock the car...the display turns on and shows the cars milage. Is there a way to change what it shows or to turn it off from showing?
Thanks!
Mine has always done this from new. Whatever mode I leave the car in when switching off it always reverts to this when switching on. Not aware of a way to disable it. May be possible in "engineering menu" but have never seen it mentioned in this forum in 6 years of reading them.
I have only owned the 2013 and 2014 C300 and that is how mine both work.
