Hello all... yesterday I finally got myself a 2013 Prius. I've always wanted one... and am loving it. I have one question though so far. How do I get it to display my lifetime MPG's? I have the Prius III package with navigation. When I turn the car off I get the reading for the last trip with the odometer reading and savings vs my F150 that got 13 miles to the gallon but was hoping to find info on what my overall mpg is for all the trips combined? Thanks in advance for any info... and have enjoyed reading this forum for a long time.
Yeah... I haven't seen an a or b odometer display. Like I say... the only time I see an odometer of any kind is when I power the car down after a trip. I know I'm missing something... All cars have tripmeters and such. And usually real time mpg stats. I'm sure its right there for me to see... but no luck so far.
There's a trip button on your steering wheel. Each time you press it, it sequences to Trip A, Trip B, distance to empty then back to the odometer. You can choose A or B as your "forever trip odometer". If you hold the trip button down for a second or more it will reset whichever trip odometer is shown at the time.
On my 2012,those A and B trip odos reset after so many miles,I think 1k miles,just like every other car I've owned.
On my Canadian 2010, trip A reads 9895.1 km. There is no space for more digits so I guess it will roll over shortly. I'll check to see if the L/100km restarts or carries on. I assume that the US cars do the same thing every 10k miles
On the event that the odometer rolls over or resets is it possible that the mpg calculation continues?
You're probably right,I've got about 14k on my car and don't remember when A or B started over.My point was,they are NOT a lifetime display,I too,would be interested to know if that's available.I don't think it is.
Most of us use Fuelly or something like it and track every fillup. It's more accurate, and you don't lose your data in the car if you accidentally hit the button too long or the dealership unhooks your battery, or something like that. One thing I've found after tracking well over 100 fillups is that the number pretty much never changes. Average being the calculation that it is, I would have to have literally dozens of monumentally different (ie. abnormally high or low) fillups to change my average. Lately I've been wondering why I even bother doing it anymore as I fill up at the same "blip" each time and reset my trips to keep track of per-tank average every fillup anyway.
Yes. Like any "average" display, once you get into the data some distance the average won't change much or very fast. The longer the average the slower the change. I use the old fashioned method - I write the numbers down and calculate the MPG. As stated above it's more accurate, though it's not necessarily accurate for one fillup, as it's difficult to fill to the same level each time. But over several fillups it gets more and more accurate. Oh, and I can still loose the data. The book I write it in could be lost or could burn in a fire.
This is what I did. There are some spreadsheet examples available on these forums, and when I use a spreadsheet backed by Google docs, I setup the Google docs spreadsheet with a web form so that I could input the data into the form via my smartphone when I'm at the pump. So, I just put a shortcut on my phone that takes me to this form. The cool thing is that building the form from the spreadsheet in Google docs allows for lists which can be populated with predefined selections so that I don't have to type everything. But the data I enter in the form goes into the Google spreadsheet like magic. And, I enable the Google form's email notification so that I would receive a confirming the data was received and input.

I intended to keep the lifetime MPG by not resetting the B odometer. However, when I took my car in for its first maintenance, one of Toyota's people reset it for me (for reasons that I have no idea why). So, not resetting the B odometer is a good possibility, but some other person might ruin your plan. I don't think you can completely prevent it. So, if you really want to do this, and to be safe, I think you'll have to manually save the numbers and calculate accordingly. My problem is that I'll forgot to write down the numbers. Mike
That's the key right there. Did this on "A" for three straight years until my dealer replaced the front passenger seat for defects. They reset everything back to zero - perhaps by pulling the battery.
