the circle around the speedometer that usually indicated if you are accelerating too fast for good fuel economy is not operating properly. what is this circle [really 2 arcs] called & what causes this
It is called Eco Assist or Ecological Drive Assist System. It is Honda's way of providing feedback directly to a driver on whether they are driving efficiently or not. Smooth accelerating and decelerating obviously saves gas and the arc glows green. More aggressive driving burns more gas and the green fades to another color (usually blue or white).
