Ford kuga 2010 61 plate rev counter green upshift light

Early models have red arrow for Max revs indicator.
Later models have an economy light which is about 2000RPM (gear dependent) except sixth.
In fact I also found out today that the green arrow also lights up again at approx 4000rpm to indicate its time to change up .....
So on the later cars it appears to be dual purpose
