The FCD button is essentially another trip odometer... super odd. It's modal; push the button to alternate between "normal odometer" and "FCD odometer" modes.
When you're in "FCD" mode:
-There's only one odometer (the "FCD Odometer").
-To clear this odometer, hold the FCD button down for a couple seconds.
-The "Trip" button (right side of instrument panel) doesn't do anything.
-Pushing the "FCD" button will switch you to "normal" mode.
When you're in "normal" mode:
-There are three odometers (A/B/lifetime).
-Pushing the "Trip" button cycles between these odometers.
-To clear an odometer, hold the "Trip" button for a couple seconds.**
-Pushing the "FCD" button will switch you to "FCD" mode.
It doesn't make any sense why the behavior is as above... but that's how it works.
Pro tip: Normally the MPG value only updates once per minute. However, you can force an update at any time by double pressing the "FCD" button.
**FYI: If pressing the "Trip" button doesn't do anything in "normal" mode, then your button is broken. This is a very common problem. New buttons cost around $1 and can be user-replaced if you know how to solder. There's a complete writeup on this forum.
