The trip computer's menu is in a variable loop. One of the alternatives is that the trip computer's three displays extinguish - this also marks the start/end of the loop.

OK - Opens the loop with the trip computer's functions + Activates the selected option.
Thumbwheel - Opens the loop with the trip computer's headings + Scrolls through the options.
RESET - Undoes, zeroes or backs out of a function after making a selection.
