I have noticed that my headlights are coming on in full sun light when set to auto. I noted advice from other threads that this maybe due to them coming on when doing over 90mph, but on my way back from 5s tonight in some lovely evening sunshine I noticed that they had come on again. I had maybe got up to 60mph max on the journey.
I was wondering whether it was maybe a shadow being cast on the sensor, or perhaps the lights are supposed to come on when the sun is low in the sky. I have checked the manual and do not see any mention of this though, mind you, nor do I see any mention of the lights coming on when doing over 90!
