I haven’t noticed any issues with unstable messages while tweaking ambient lighting. If you could share a screenshot or the exact wording of the warning, that would help.
I’m thinking you might be in accessory mode, which could trigger a warning about draining the 12v battery or anything, not sure about that though.
Just last week, I ran into that same annoying error message while trying to tweak the charging settings on my car, which is still practically fresh out of the box at just three weeks old! I've been at it, but I still can’t figure out what’s causing the hiccup.
It is very possible that the system might be having trouble processing the changes you made to the interior lighting. It could be a temporary glitch, so try restarting the car to see if that clears the message.
