Note: This does not apply to Pakistani Civics
Oil change is just one of the things it displays. It displays the type of service that the car needs, whether a simple oil and oil filter change, or a more extensive service.
You will not find the maintenance schedule in the owner's manual of the Civic, because the maintenance minder determines the schedule for you. This way, you will only need to do the necessary service; no more and no less. The dealers won't be able to rip you off. You can save a lot of money this way.
