Use this method: turn the key to the run, (II) position. Push in the odometer reset button and hold it in. Turn key off and then back on, still holding down the odometer reset button. In a few seconds the service light will begin to flash. When it does, release the odometer button, and turn off the key. The light will be reset and won't come on again for another 7500 miles. This method doesn't work on '98's, I'm told, but it does on my '99.
