    While showing off the car I accidently hit the reset button. Is there anyway to get my current tank mileage back?

    Sorry.
    I had to take Priapus in for work and they had to disconnect the 12v which wiped everything out.

    I ran the tank to the normal refill level (usually one bar blinking). Then, using the ODO reading, I calculated the number of miles driven between refills. Using the amount of gasoline I refilled with, I was able to calcualte the MPG. It shouldn't be too far off what the MFD would have shown.

    For other people with reading comprehension issues, he's talking about the "amount of gasoline [he] refilled with" previously.

    Reading this thread I first read "Can I undo by hitting the reset button" and it reminded me of a xbox360 game called full auto where you have a rewind button for when you crash your car

    Did I misread/misunderstand or are you saying that my post was difficult to understand. Neither one would surprise me much.

    In the event that it's the latter, allow me to explain a little better since I did seem to skim quite a bit up there.
    We'll start with a completely filled tank and an ODO showing 15,478.
    Approximately 200 miles into the tank, I hit the [RESET] button or whatever. The numbers on the MFD are now officially bumpkiss.
    Refill occurs about 300 miles later and requires 9.8 gallons. The ODO shows 15,982.

    This means that I traveled 504 miles, consumed 9.8 gallons, and averaged a paultry 51.43 MPG. It's purely a measurement of how far I drove since the last refill and how much gas it took to get there. Unfortunately, if you do not have the ODO reading from the most recent refill, you can't do the math.

    Okay, so apparently I read it the first time the way you meant it. But with fillups varying so much with the bladder I thought I might be reading it wrong. I then noticed you didn't actually say to refill the car. And that actually made more sense to me, because I bet that the actual amount of fuel in the tank whenever the last bar starts blinking is much more consistant than the amount of fuel in the tank whenever it has just been filled. Actually, I guess the way you're talking about doing it depends on both amounts being consistant, so using the previous fillup amount does seems like the way to go.

    Anyway, I found it pretty interesting to split up a couple tanks, and reset after each little trip. Okay, it's 20 cents to go to the library and back, 50 cents to work this way, 75 cents that way. I used trip A to get the mileage to the tenth (then added .05 to round correctly) and trip B to make sure I was still accurate for the whole tank. You can check out the 2nd sheet in my spreadsheet if you're interested.

    I'm keeping a lifetime average on the computer, so I reset occasionally like jeneric does.

    (Sorry, I don't reset, but I reset the MFD.) :)

    Just a note.

    Be careful when cleaning the MFD. Don't clean it when on this screen, switch to the map or consumption screen. Have read about "premature reset," though I never experienced it myself, of course.

    I'm still on my first tank and wondering if I should press 'reset' when I ultimately stop for a fill-up. What do most people do here? Reset with every fill-up, or never reset to see the lifetime average?

    No comment on 'premature reset'. :mellow:

    In the manual, it states that the mileage number will reset to zero when you put in a few gallons of gas (2.5gal comes to mind). Apparently the average MPG does not reset.

    Since I keep lifetime MPG figures in a spreadsheet, I reset the MFD periodically to demonstrate trip MPG when I'm curious.

    Hope you or someone reading this can help me.

    Just received our 2006 silver package 3 Prius. How do I get to the Lifetime MPG screen? Is this a permanent on going average, or do you u lose the lifetime when you hit reset? If so, why is it called lifetime? The manual does not seem to be to clear, as I have tried to figure this out via the manual.

    Anyone who quotes "lifetime MPG" figures keeps a spreadsheet. The only figures available on the 2004-2006 Prius screen are tank MPG and miles traveled. If you fill up with more than about 3 gallons, both figures automatically reset to zero (after all 10 bars are lit and a few revolutions of the wheel).

    When I fill up, I turn the car to IG-ON mode (two presses of the power button with NO foot on the brake) so I can write down odomerter reading, trip odometer, and trip MPG, and then I wait for all 10 bars on the gas gauge to be lit. THEN I put my foot on the brake and hit the power button again, and it immediately goes into READY mode (without the 7-second wait). Before I leave the gas station, the trip odometer has reset to zero.

    My 2004 reset both the miles traveled and MPG since last refill, BUT, my 2006 only resets the miles traveled. The MPG seems to be a lifetime unless you RESET. Does this match other 2006 owners?

    On my 2006 the mpg does not reset at fill up only the miles. Just like yours.

    When I fill up my 2006 Prius, the milage automatically resets, but not the MPG.

    On the other hand, I don't believe the MPG shown is a true "lifetime average" though, because it responds to extreems too easily. A true lifetime average would not really budge much if you had a few low MPG trips in a row or a few really high ones in a row. The more miles on your ODO, the more firm your lifetime MPG would be.

    Perhaps it is an average of the latest 500 miles or something... Anyone know?

    I've managed to accidentally hit the reset button so many times that I rarely use the consumption screen out of fear that I will accidentally lose my mileage tracking. I would dearly love to find a way to disable the reset button and actually recover the total lifetime mileage value. Has someone investigated this? I'm interested in seeing someone find a solution like was done for the annoying backup beeping.
