Being new to the forum I am not sure if this the correct place to post this but here goes:- I have just bought a 2017 E220d (W213) Estate and sometimes when manoeuvring the letters LIM appear at the top left hand side of the parking sensor display (the one next to the camera display that shows "radar" lines). Does anyone have any idea what this is trying to tell me? I know LIM usually refers to the speed limiter but is it something different in this instance? There is no mention of it in the surprisingly poor Mercedes manual. Thanks.
