HELP! I cannot reset the Average MPGs on my Consumption display.

I have a "new to me" 2009 Touring that I purchased on 9/2/10. She had approximately 35K miles on her and an Average MPG of 39.6. While I have managed to increase that average up to 41.7, I'm tired of looking at the results of the previous owner's bad habits.

I have hit the Reset button on the Consumption screen several times, but the only thing resetting is the number of miles driven. I have reset both the Trip A and Trip B Odometers, again the only change is the trip odometer reading, NOT the Average MPGs.

This is making me a little crazy as my previous car was a 2004 Prius and the Average MPGs AND miles driven automatically reset any time I filled up with fuel.

Please.....I need someone to offer me a "fix" for this situation, I've been looking in these threads for over 3 weeks and I can't seem to find the answer anywhere.

Thank you for any and all assistance, in advance

Is it possible that I'm missing a simple, but obviously important, step???

 

If you're asking about the reset button on the Consumption Display, that's the only reset button that I know of, so Yes......
(the Trip Odometer resetting was done by holding down the trip/odo button)

Thanks,

No problem!

 

I've toggled back and forth between the Consumption and Energy screens, I haven't seen any issues when on the audio/climate/phone/navigation screens.

I'm not sure I understand what you mean when you say touch other parts of the screen to see if it will trigger the reset.

 

Will this cause everything to be reset as Politburo indicated?

 

BUMMER!

I purchased this as a Toyota Certified Pre-Owned Vehicle, do you think the mechanics at the dealership would be able to correct the situation? I'm not sure that I can disconnect the 12v battery myself.

 

I have fueled up 3 or 4 times and have been pushing the buttons for just over a month....not sure how much longer I can take it!!!

 

Thanks, Patrick.......fuses I can do! I'll give this a shot over the weekend. Do I need leave them out for the 5 minutes as suggested for the battery terminal or just long enough to get them all out and then put them all back in?

Thanks again!

Okay.....so on my way to my Mother's home last night (a 65 mile trip), I'm thinking and thinking about all the little pearls of wisdom I've read on this discussion board. I kept coming back to all the threads related to the display lockouts while the car is moving and I thought "I"ve always been driving when resetting so that I could zero out at the right time". Soooo I decided to try the reset ONE MORE TIME when I PARKED at my Mom's and low and behold......what a BEATUTIFIL sight of 0.0 MPG! :dance:

Thank you for all the suggestions. I'm off to post on the "Most Obscure Prius Facts" thread! :grouphug:

Have a great weekend!
