According to the owners manual for my 11 TL, there is a setting that can allow Mileage A, MPG and such to reset to 0 when refueling. I thought I activated the feature during the initial set-up of the vehicle. So far, the setting has never automatically reset. I must use the button on the steering wheel to do so. Am I missing a step somewhere? As always, thanks in advance for any information you can share.

 

Not sure never had to turn it on my 2010. It just worked, cuz I forgot to check before refuel, went to go refuel, get back in and it was at 0... I was like dangit needed to measure that amount lol! That was from 1/4 or less tank to just incase it only does at certain amounts? Not sure if it is any refuel or only below certain levels.

Hope you figure out, call to dealer might help but sure its in the manual as well.
