Reset MPG average

I reset mine every time I fill my tank while the car is stationary and it gives me a true reading after the first mile or two. Same with the Average Speed.
It's MPG since the last reset.

I don't get it either. Why you need to reset the average MPG while the car is rolling? I reset it anytime I want and I do get pretty accurate average MPG reading every time.
Yeah, since last reset. The INFO rocker switch is 3-position push-button switch and the middle position is for the reset.
Maybe they fixed it on newer models. On my 2014.5 CX-5 if you reset while sitting still, it will read very low AVG MPG (17mpg) and take 50 miles to creep up to actual 28mpg. If you reset while rolling, and drive 5 miles, it will show 28mpg right away.
I doubt that's a newer model thing. If you start from a dead stop when you leave the gas station and are travelling city streets for a while, your average MPG will be low because of the constant use of the accelerator. If you reset average MPG while driving on the highway, your average MPG will be higher because of less frequent use of the accelerator.
My 2014.5 takes several days to display correct AVG MPG if reset from a stop, or about 50 miles. If reset from a roll and driven 5 minutes, the AVG MPG is correct. Can't imagine it varies from car to car. It an error in averaging by computer.
I just found the option to reset Average MPG when you reset the Trip A odometer. While the car is on, but not moving, if you go into the Info Screen on the instrument cluster, then into Averages, there should be an option under Average MPG to reset it when you reset Trip A.
