To the left of the steering wheel should be 2 dials, one farthest from the steering wheel is for the gauges and dome light on/off. The second is closest to the wheel and controls accent lighting brightness..
I find it odd that the red "island" or whatever they call it is not lit up. If adjusting the brightness with that dial doesn't fix the problem, I know there is an interior lighting fuse. (location is as usually, open driver door and the cover is on the side of the dash.)
