Changing Odometer/Trip from km to miles - Need Help

Here is what I have tried, so far:

Have to hold the "reset" button before turning vehicle on. The "gauge test" is first up and goes into a test immediately. After the test, nothing seems to happen, so I hit "reset" again.

The second menu looks like it might be where km/mi display might be changed, but nothing I do has any effect. Trying to press and hold it at that point just takes me to the next menu item.

BTW, does anyone know a good source to explain all the other abbreviations that show during the tests?
