There are 2 way to reset the maintenance light on Civic.
1. Manually reset
To reset this maintenance light, you will put the key in the ignition. Next you will press and hold the odometer reset knob, which can be found on the dash where the car's current mileage is located. While you continue holding that know, you will turn the key to the first position but do not start the engine. After about 10 seconds, the maintenance light should disappear. If the light is still on, you can turn off the vehicle and then try the process again. Once the light is off, you are all set until your next schedule maintenance.
2. Hook up a HDS (Honda Diagnostic System) software on a laptop, the light will go off within minutes.
