Here's how to reset the maintenance indicator light on a 2003 Honda Accord LX:
1. Turn the ignition switch to the "ON" position (without starting the engine).
2. Locate the trip odometer reset button. This is usually a small button on the instrument cluster, often near the speedometer. It might be labeled "TRIP" or have a small arrow symbol.
3. Press and hold the trip odometer reset button.
4. While holding the button, turn the ignition key to the "OFF" position. You should continue holding the button for a few seconds *after* turning the key off.
5. Release the button.
The maintenance required light should now be off. If it doesn't reset after attempting this process, try repeating the steps.
Important Note: If the light comes back on shortly after, there might be another maintenance item due besides the oil change. Check your owner's manual to see what other services might be needed based on your mileage. Ignoring maintenance alerts can lead to more significant problems down the line.
