Can some one please clear this up for me. I have a 07 Pack #2 and reset the consumption "RESET BUTTON" each time I fill up. I see this resets the miles driven to Zero , is the new
"AVERAGE" [of miles per gallon] for this tank full only ? OR For the life time of the car ?

Thank you,
Terry

on the 07, pressing reset will reset both the mpg and miles.
If you do this at every fill up, you will have the tank average mpg and miles on the tank.
By keeping track of each tank MPG and tank miles you can figure your lifetime MPG.

Aparently, though I've never done this. If you never press reset, the MPG readout is never reset and so it will read your lifetime MPG, however the miles gets reset automatically within a few miles of each fill up automatically.

Sometimes if they have to do something on your car though, like um, unplug your battery for some reason while they're doing something in the shop.. it will reset your MPG/miles on the MFD :(. This has happened twice.. once when they fixed the rattle under my dash, and the last when they had to replace the HID controllers/assembly.

I have an 2006 Prius. With each fillup I religiously write down on a printed spreadsheet form the date, the odometer, miles driven since last fillup, the gallons I put in, the calculated mpg, the MFD mpg, the price per gallon I paid, and the total cost.

Sometimes, the MFD resets automatically before I had a chance to write down its reported mpg. This happens only occasionally and I can't seem to figure out what triggers it. It happens when I restart the car after filing up. My best guess is that it only happens when I take on more than 10.5 gallons but it's still not consistent. I have made a habit of simply taking a mental note of the mpg before filling up.

Did you do that with the cars you had *before* your Prius?

Actually, I did, sort of, but only enough to calculate and record the mileage. I usually have the luxury of doing the recording while my wife drives.

I did with my Saturn when I was given a calculator/notepad as a vendor promo at work.

Which reminds me, I still didn't record my fillup from Wednsday.

As for reset, it takes a little time for the Prius to acknowledge a complete fillup. You'll notice that the gas guage slowly climbs. So if you take off right away, then the car hasn't yet registered that you had filled up enough to warrant a reset until a mile or so down the road. I usually have the car in at least Ig-On if not READY as I record everything, so by the time I am ready to roll, the guage shows full, so it resets immediately (maybe half a turn of the wheel) on taking off. That is, if I didn't manually reset it already.

This is the first time I've heard this. Is this correct? It seems like a strange combination-- to reset the miles, but not the MPG. My next door neighbor just got a 2007 and I don't want to give him wrong info.

That is correct. The 04 and 05 Prius automatically resets the mileage and MPG at each fill-up. The 06 and 07 resets the mileage but not the MPG. To reset the MPG you have to do it manually using the soft reset button on the Consumption screen

Thanks. I still think it is a strange combination. I wish the MPGometer was similar to the odometer/tripometer-- one lifetime and two resettable.
