45mpg

I finally cycled through my LED console display on my 2015 Yaris and saw that I averaged 32.2 mpg during my first week of ownership. Except for jumping on the highway to zip down a few exits here and there, all my driving is typically city street-light to street-light commute type driving here in Phoenix, so I am not surprised that I am only averaging lower-end "CITY MPG".

It dawned on me last week after I posted this that I never reset the Avg. MPG Computer on my console display when I first received my car, so no telling what data was already in it. I reset it, and halfway into my second week of driving my new 2015 SE m/t I am averaging 37.6 MPG on my daily in-town work commute and errands. Much better!

I don't know if such funtionschanged with the '15, or if I suffer from a lack of knowledge because I only skimmed over the owner's manual . I followed what some others have posted and assumed that the avg mpg reading = for the life of the car and isn't able to be reset. Don't know if the '12-'14 can't be reset, or if those years are the same as the '15 . I should probably look at the owner's manual . I've never reset mine, and it shows 40.6 MPG. Others have pointed out that this gauge probably overstates because when you take your foot off the gas, etc. the gauge often goes to 99.9, and you really aren't getting 99.9 MPG during those (albeit short) periods.

Yeah, the 'real time' MPG function seems sort of worthless/annoying, as it jumps around a lot while you drive depending upon the exact circumstance at the moment.

I prefer the 'average' MPG function. When I pressed the button and held it down, the old 32.X 'average' reset to 0, and then seemed to restart from that point on - as it was less then 20mpg for the first few minutes of driving, while leaving my house and poking around my neighborhood streets in 1st/2nd gear before hitting the main road. The'average' display on mine never jumps around, and slowly either goes up or down by 0.1 (or stays the same) as you drive under different conditions.

I meant the average MPG function re the my 40.6 since new and the '99.99' as a 'default' on the 'instantaneous MPG' gauge/reading when you take your foot off the gas, etc . I didn't know the average MPG gauge/reading was able to be reset at all until your post (it would probably make sense that this is a function that also exists on the '12-'14...I just didn't know about it re only scanning the owner's manual). The display on my 'Average MPG Gauge' behaves just like your description re your 'Average MPG Gauge', and the display on my 'Instantaneous MPG Gauge' behaves just like your description re your 'Instantaneous MPG Gauge'.

When other posters have mentioned the '99.9' on the 'instantaneous MPG Gauge' in various posts, they have usually done so (at least in my observation) re how the '99.9' MPG on the 'Instantaneous MPG Gauge' ends up effecting (overstating) the Average MPG reading. These past posts led me to think that the Average MPG Gauge 'Calculates' using (fully or partially) some sort of sampling of the 'Instantaneous MPG'. Those past posts from others re the effect any '99.9' instantaneous readings have on the 'Average MPG reading' could be 'all wet', so to speak .

I just use the 'Average MPG Gauge' as a guide. I still do an old school written log book, and calculate each tank separately.

I averaged 38.2 MPG for the week, after AVG MPG computer reset last week (to clear out any pre-delivery/purchase data). Almost all in-town "city driving" for my weekly work commute and errands. Even with a decent margin of error for the computer calculations, I should easily be averaging 35+ MPG weekly. Very satisfied!
