welp first off that light is telling you you to get an oil change (goes off every 7500 miles i believe)
anyway to turn it off on an integra:
look under the driverside dash kinda close to the center console
you will see a little button ( i think its blue )
with the key in the off position, press and hold the button
turn the key to the on position, dont start the car, still holding the button
after a few seconds, the maitenence light will blink a few times and then turn off
release the button turn the key off then start the car
the light should be off
