For digital ODO:

3. Press and hold trip button for a few seconds
4. Continue to hold button while turning ignition to ON position.
5. Hold button for 4 more seconds then release
6. Press button again and a 1 or 2 digit number should appear. I'm not exactly sure what this number represents, but 10,000 km lots until next belt change might be a reasonable guess.
