I found it on an other forum and it works.
1. turn ignition to ON position.
2. toggle the trip/odometer display to display Odometer.
3. turn ignition to OFF position.
4. WHILE holding the ODOMETER button down, TURN the ignition to the ON position. Keep holding the ODOMETER button down until you see the light stay on in 2 seconds and then flash and then OFF.
turn ignition off and then back on to confirm that it's off.
