Lights out

I have a 2001 Honda Civic that I no longer take to the dealer for service. But the maintenance required loght has been on for months and the friend that fixes my car doesn’t know how to turn it off. Do you have any hints.? Its driving me nuts.

Push and hold the reset button for the odometer. Insert the ignition key and turn the ignition switch to the run position so that the dash lights come on. Continue holding the reset button for ten seconds until the light turns off.
