When it gets overcast/dull/dusk, my headlights come on, the instrument binacle lights up as does the sat nav, However, the control buttons for the telephone, heater, radio etc do not! Now when it gets darker, they do suddenly spring to life. It's like the car's telling me "I don't think you need these illuminated yet". I can't seem to trick it either by manually turning on the headlights. Does it know something I don't?
