How do I display average MPG on 2013 Prius - by tankful

TJM, not too sure but I think after you fill the tank, select the trip meter (A or B) and reset to 0, then the MPG should reset for that Trip (A or B) and you will begin to track the MPG.

Brian - thanks for the response. Stopped a woman in Post Office parking lot - she showed me how - her 14 yr old son had figured it out. All Prius' should come with 14 yr old to explain them!

Mark, could you please tell me what the 14 year old said so I can do it too? We've been going crazy. The 2005 seemed more intuitive.

First off - you are correct - the older Prius' were more intuitive. Toyota has outdone themselves with useless software. 1. Set the two TRIP buttons to ZERO 2. Set the display button to Hybrid Systems Indicator - that's it. I have been using Trip A for each gas tank, and just letting B run on, showing the total MPG over a longer period of time

Thank you! I will try that!
