Best MFD indicators for good mpg's?

Try to keep your instant MPG readout at least half your MPH while accellerating.
When slowing down or in city travel below 40 MPH do a glide with no arrows, just barely feather the pedal (enough to not have blue, but not quite yellow). You want to barely ever have all yellow arrows as it is more inefficient to recharge the battery. I use it only for idling through parking lots and the rare instance when you know you are about to go down a long hill and will be able to regen on the way down. As far as Highway travel just drive steady and non aggressively. That seems to work for me.

 

if you want my best tips for good mileage.
1) air pressure at least 40 front 38 rear (if not higher, your handling will vary)
2) Turn off your climate control for the first 5 - 10 minutes of all your trips. (if safe to do so with no foggy windshield)
3) Look ahead at the patterns of traffic lights and know your route, if you know what hills you can glide down and what lights you can glide to before hand you have an advantage.
4) I don't get to much into the pulse and glide thing, My opinion it is too easy to do it wrong. I save all my glides for traffic, hills, and upcoming stops. and now that the weather is getting warmer I'm back up to 53 MPG.

 

This is how I drive as well. I do put more air in my tires but the rest is exactly the same.

 

Also:

Don't tailgate!

Everytime you touch the brakes, you just gave away some of the gas you bought. If you leave enough following distance, even when traffic slows, you can often maintain your momentum when it moves again. Even with the regenerative braking, you're going to lose at least 50% of that energy.

I have found that the biggest obstacle for getting good mileage is other people.

 

...and at least partially block your grill.
