Stating the obvious here, but are you stuck in the MPG mode? press the stick on the instrument panel to cycle between Trip 1, Trip 2, MPG, and a few other things I'm forgetting.

Hold the button in and it will reset. Here is an explanation on how it works: http://www.toyota-4runner.org/5th-g...les-empty-range-indicator-operates-print.html
It's a strange system to be sure. My Avalon never needs resetting and it continuously calculates and updates the fuel consumption. And it's 12 years old.

My wife's 05 Camry has an "instant" and an "average" MPG readout. You may be thinking of the instant readout. I can't speak for the 10-13 4Rs, but my 14's "instant" readout is just a bar graph, with the "average" as a numeric display in a different window. The average can be reset while the instant can't.
The point I was making above is if you run 10 tanks of gas through it without resetting the average MPG, it is going to indicate the average across all of the miles from those 10 tanks (3,500-4,000 miles?). So any change will be very minimal, if at all the longer you run without resetting it. I ran a 21 mpg tank through mine a couple weeks ago on a leisurely cruise through the Texas Hill country. The next day I topped off and reset. I refueled 200 miles later having run maybe 6 or 7 miles in 4 lo and off road. That tank showed a 14.3 mpg average. But if I had never reset the meter over several thousand miles that may have only brought an overall change in my average from 18.0 to 17.9.
It's like how a baseball player's batting average becomes harder and harder to change over the course of a season. Even if a guy has a big hitting streak somewhere during the late season his average won't change very much because of the 400+ other at bats he is being averaged against. If they reset every game some guys could finish the year with an .800 or better average.

lol on my 2014 I cant eve see to figure out where the speed needle is sitting inbetween ticks, so I have my main display always set to digital speed readout.
and the speed needle seems to be off by 1mph compared to the digital readout it seems. when it looks like dead center on the 60 tick, the readout says 59.

No, I understand. Both of my Toyotas have instant and average fuel consumption readouts. I leave them both on average 99 percent of the time.
When I said it's a strange system I was comparing my 2012 4runner to my 2003 Avalon. In average mode, the Avalon will update and, for the most part, reflect a reasonably close rate of fuel use without ever having to be reset (Frankly, I don't even think there is a reset option on that car, but don't quote me just yet). This is compared to several hand calculations I've done.
In the 4runner, I think your description of how that monitor works is accurate: it keeps data points ad infinitum and just seems to get "stuck" as it were. It might be more accurate over long periods of time, but I like the day-to-day, or even weekly results shown in the Avalon more.
The difference is probably that the Avalon dumps data and refreshes it's calculation more frequently, whereas the 4runner doesn't.
On another difference between the two, again preference going to the Avalons way of doing things, the 4runner uses two buttons to control the sunroof/moonroof. The Avalon uses one. These buttons accomplish the exact same things, venting and opening/closing the sunroof. But, the Avalon designers put it all into one button.
Sometimes, it seems to me, you need to leave good enough alone.

well I do know the time duration of trip counter rolls over since I have never reset it. on the few occasions I have flip thru that part I have seen high and low numbers for it.
as for the avg/instant, I haven't reset that since I picked mine up since I use an app to track all my service/fillup/maint/addons for the 4runner and Tacoma.
I haven't seen the avg budge from 15.x since I have bought mine back in 04-dec-13.
