Hi, Can someone tell me the function of the small battery icon at the top of the infotainment screen? More often than not it is coloured fully green but occasionally only half green?

Thanks for the reply. I checked again last night and notice that the button will illuminate when pressed but no option to change driving mode shows up on the infotainment screen, in fact the screen doesn't change from whatever is being displayed at the time. Having looked on youtube it appears that there should be an indicator on the top left of the screen showing which mode is currently selected but there's nothing showing on mine.

Have just tried to adjust the driving mode on my 2016 1.6Tdi SE Business Estate but the mode button seems not to do anything when pressed and there is no indication on any of the displays what the current driving mode is set to. Is it a case that my car doesn't have this feature ( in which case why provide a dummy button ) or is there another reason?
