The dots are a form of 'Blending' between the top/right/lower/and left direction arrow airflow indications. For instance, if you place the indicator to 3 oclock and turn it clockwise one click, it'll partially direct the flow to the 6 oclock position vents indicated at that 6 oclock position. See, it blends 2/3'rds to the 3 oclock position and 1/3rd to the 6 oclock positional vents listed. You might have to download the owners manual at the forum page for the documents collection (if I have totally flummoxed you trying to follow my overly detailed explanation). Good luck! And welcome, I know you'll do George proud caring for your new XF!
