This gage shows when the vehicle is operating at a fuel efficient point.

By modifying driving behavior to increase the economy time during driving, fuel mileage will be improved. When driving in a way that increases the fuel economy, the indicator moves into the high efficiency band. When driving in a way that decreases fuel economy, the indicator moves into the less efficient band. There are several zones on the gage, indicating several levels of efficiency when accelerating or decelerating.
