Back lighting on dash only functions when night headlights are on , not with daytime running light . Also you can scroll to settings with the menu toggle and adjust the brightness. Check in your manual for specific procedure. Can't remember the exact steps but if you scroll to settings then to adjust backlighting, then to level 1 2 or 3 you push to lock it in. Again from memory so I may have missed something . I can go to the garage and run through it if you need me to .
