1. Turn the ignition to run (one position before starting engine). 2. Bring up the odometer reading using the trip meter reset knob then the turn ignition off. 3. Hold down knob while turning the ignition key to the run position (one position before starting engine). 4. Hold down the knob until the light goes off.
