The miles-to-empty estimate resets itself after each fill-up, but the running MPG tallies are tied to the car's two trip odometers. Reset one of the trip odometers and it resets the mileage calculation for that trip odometer. Push the button on the left side of the instrument cluster to change odometers, and you'll see the running MPG calc change accordingly.Someone mentioned resetting their avg MPG indicator every fill up. How does one manually reset it? Mine resets itself when you re-fuel.
I'm over in central OR and do regular trips to northern CA. The interesting thing I found is avg mpg relative to altitude, since all other factors are similar. Maybe this is a known fact. I'm guessing with altitude and subsequent leaner air the computer is adjusting fuel accordingly. So while overall power might suffer at elevation, cursing under nominal load means less fuel at the jets.I took a trip to Bend and back yesterday thru Salem and over Santiam Pass. Went from about 90ft above sea level to a little over 4800 there and back. Had a tailwind on the way back down the mountain. After driving 433.2 miles, I filled up today and it took only 11.024 gallons which equates to 39.3 mpg, my best ever! The Average MPG indicator said 40.2 so it was closer than most fillups.
I'd have to disagree to your point. The cruise is electronically controlled speed controller and it's meant to maintain speed. Manual feather of the peddle is less likely produce better MPG than using the cruise. Today's CVTs are well matched to the cruise uphill/downhill, etc... and whether you use cruise or manual, you'll have to increase the RPM to maintain speed and my guess is that our ECUs can out-maneuver any heal/toe manual throttling.Careful of Cruise! It can kill MPG. Its purpose is to maintain speed. On hills and inclines it will increase RPMs to maintain speed. This means it may burn more gas then if you gradually maitained the speed manually.
I agree with this-- maintaining a constant speed will not always result in the best gas mileage. I can see the road ahead and make decisions the car cannot. For example on a short steep up and down it is more economical to drop a little speed along the way up and then have gravity make it up for you on the way back down rather than maintaining a speed up the hill with cruise and converting that speed to brake dust on the way down.Maybe so, but they can't anticipate ups and downs, whereas you can because you can see them coming.
