Salam,
I am owner of honda N box+ 2013 model, the ambient speedometer light used to be solid green, o ne day on moterway it suddenly changed to white with acceleration. And when i decelerate it turn green. I have searched online and its ECO assist honda function for drivers to drive efficiently.
Strange thing is that it stayed solid green for the past 1 year and the car fuel average was 20 with normal foot. Now it hardly gives 13 with extra light foot.
Car battery is under warranty and in perfect condition. No codes nothing, car is running perfectly except fuel average.
Did any one else's speedometer light stayed solid green, or it changes with acceleration.
