The top two bars are green, the bottom are violet. They represent a full and low SOC

I believe the consumption screen bars are laid out in 1 minute increments. Deceptive untill you understand them because speed and actual distance coverd is not easily compared when your looking at a mpg reading over time.

The bar graph on the fan works well once you get used to recognizing it.

The ENERGY screen will teach you to understand how your system works. One specific mode, not shown on the non-nav system is when the ICE is driving the wheels AND charging the battery. When I am in that mode in rolling hills I am able to achieve >50 mpg. Your terrain may not allow for that. If you watch the screen for a while you will understand the system.

As far as maximizing FE, the handiest item is still the instant FE gage on the left side of the dash. It's a constant reminder to lift your foot.
