Optima Ambient lighting (Platinum, GT-Line, GT and PHEV)

Hello dear KIA-community! I would like to turn to the Optima-employee in particular: When buying I had not even paid attention to it, or for some time now not thought about it… at some point it came to mind again. According to the brochure Optima from platinum or also in GT-Line, GT and PHEV have an ambience lighting as standard with it… now I ask myself, of course, where this ambience lighting is. Have already searched all the menus in my PHEV and also the I … but unfortunately I won’t find out. Has someone already wondered the same thing or maybe even figured out what it is about? Perhaps with an explanation where that is and how to get it started.
