I tried to push the Trip button all the way possible, for like 300 times. But its still not working. What is weird is that when I push the Trip button for several seconds, it resets my Trip A (where my Trip A-Trip B-Lifetime display is stuck).
Also, I did 80.8 MPG on the FCD on my commute to CEGEP :
Took a picture of the engine bay :
And a picture of the trunk :
