How do i reset the maintenance required light?

On the typical Honda gauge layout, there is a small, rectangular, recessed button directly to the left of the "Maintenance Required" light. Using a key, you can press this button in, With the key off, hold down the trip meter reset button. turn the key on and continue holding the reset button in until the maintenance light goes off, about 10 seconds. which will cause the light to turn green. The maintenance light (at least on Civic) will come on about every 4000 miles if not reset (for oil changes), and also periodically for other scheduled maintenance.
