2018 Corolla LE: Avg MPG Display: 20.8 ???

#3
Press and hold the DISP button on your steering wheel to reset the average mpg. Mine was stuck at 26mpg when I first got mine, no matter how much highway driving I did. I reset mine after every fill up and it shows 32 to 36mpg average per tank with the type of driving I do.
