I have a V6 with the Premium Package (not the Tech). Yesterday, I noticed that the instrument lighting kept switching betweeen very bright and very dim regardless of whether the lights were set to "parking lights", "headlights", or "auto". This happened around dusk. I suspect that I have a lighting problem, but does anyone know if there is a "feature" that dims the instrument lights under certain outside lighting conditions? Again, this happened well after the lights were set to "on", not when the switch was first moved from "off" to "on". Has anyone else experienced this? Thanks!!
