depending on your year integra there are 2 ways to get rid of the light....or maybe 3

1 if you have a 96 integra there is a key slot on the left side of your steering wheel to the bottom all you have to do is insert the key and it will reset

2. if you have an older integra there is a bluish green button located to the right of the steering wheel and under near the pedals you will have to look almost up at it lying down near the pedals to see it hold the button down for a few secs and it will clear

3 any newer then 96 or older then gen 3 integras i would consult the owners manual or if you dont have it call an acura dealership and ask them where the reset is located

the maint req light is set off according to mileage to the last time it was reset depending on the mileage it will blink or stay on for ignition or in your case (over 7500 miles) stay on...
