Now I'm sure I'm not going mad. But I was driving the other day and I'm sure every time I went through a shady patch the dial lighting on my 500s would come on. Going in to the light and hey presto off they would go again. My other car has auto lights and intelligent interior illumination, I wasn't aware that the 500 did any of that kind of stuff. Is this a normal standard feature on a 2014 s???
