Hello together, is there a trick at Arona to adjust the brightness of the instrument lighting? My dealer is overwhelmed and doesn’t know what to do. We found the entry in the menu / setup, but as soon as you want to set a value that is 100% different, only the message “Function not available”. Do you have to activate something somewhere before? Thanks for tips! Menu: “Car”=>”Setup”=>”Light”=>”Interior lighting”
