First I always have the MFD displaying the battery\Ice. I also usually keep the consumption screen up on the Nav display.

As far as being at 60MPG I have this happen sometimes when I am coasting and other times the MFD shows dual power (Ice\Electric).

I think I have caught on pretty quick, with some help from this site, as to how to feather the pedal to get into E-mode and how to deal with hills. On some of the different routes I drive I will try and reach the speed limit +5mph by the crest of the hill, while in E-mode, so that after I crest I will start to go more than +5mph over and thus get a little brake regen in while I get myself back closer to the speed limit. I have noticed that as it has warmed up I have been able to achieve E-mode right up to 45mph at times.

I have already seen the 99mpg figure after refueling. It was quit amusing.

"If you're coasting with a cold engine at 30 miles per hour, are you burning gas when the needle is at 60MPG?" I had wondered this too. As both the MFD and the Energy screen show the ICE is off.
