This is killing me too. The auto setting is too bright in the night. I tried manual and it does not allow me to make changes when lights are on.
It sucks. I will be going to the dealer tomorrow and get some info. Stay tuned.
OK. So you can change it using the controls on the steering wheel. Go to vehicle settings and then to backlight. There you can chose to what you like. Will it stay like that when you start next day, I will find out tomorrow
