MFD MPG resetting itself...

<div class='quotetop'>QUOTE(Rufaro @ Jul 26 2006, 06:08 PM) [snapback]292792[/snapback]</div>

I'm not clear what you mean - assu,ing your 'odometer/trip meter is on trip A, do you mean you clear trip A by holding down the ODO button, then press it again to display trip B, then hold it down to clear trip B? If that's what you mean, then the MFD MPG SHOULDN'T reset itself. It should ONLY reset itself if you press the 'RESET' on the MFD consumption screen, I believe.

I think my 2006 manual says that the MPG and miles shown on the consumption screen is supposed to reset itself when you fill the gas tank, but I've never had that happen.

Caveat: I've never re-set my trip B meter - it shows the miles I've driven since I bought the car in April. The odometer is about 65 miles more, because the car had been test-driven a lot before I bought it.

 

The MFD MPG will reset itself when you fill up, but not (on mine) instantly. But this has no connection with resetting the trip-meter mileage, other than the fact that both usually occur when you fill up.

Doesn't the trip odomenter only go to 999 miles? It does on the '04 then goes back to zero!

When I first bought my '04 the MFD never reset on a new tank of gas. I liked that because I could see the mileage for an entire trip of several tankfulls. With a computer upgrade during a TSB now the MFD always resets when I fill up. I liked the other way better.

To agree with the answers to the first post, resetting the ODO/Trip meters should not effect the MFD in any way.

Ditto

Sometimes it does and sometimes it does not reset. Go figure.

Although only by experience, I believe that only the mileage on the MFD screen resets to 0 after a fill-up. I believe the MPG average doesn't reset unless you press the reset button. So, potentially, you could have lifetime MPG average (while the mileage display next to it resets each fill-up).

The 2006 is apparently different in this regard than the pre-2006 (which reset both miles and mpg).

It sounds as if you're confusing "mileage"---not "gas mileage"---which displays on the bottom of your MFD, with MPG.

MPG displays only in one place, the bottom of the MFD screen. "Mileage" displays both on yer odometer AND on the MFD. What davis is saying is that on the 06, no. of miles driven (mileage) resets itself, but MPG doesn't. Thus, if you never reset your MFD manually, as you clear your odometer miles, your MFD MPG number will become a cumulative average, spread over several tankfuls of gas---even LIFETIME MPG if never reset.

If I may confuse you more, please let me know.

My trip meter B is showing over 2700 miles at the moment in my 2006, so I guess it's different from the 2004 model.
