You got it, that little light tells you a service is due on your auto. You probably were proactive and did the oil change early and now the mileage has tripped the light telling you a service is due. There may be other things that should be checked at this mileage besides the oil and your maintenance schedule in the owners manual should confirm this. Normally the dealer would complete the maintenacne items for this mileage and reset the light as part of the servcice.

The oil change light system needs to be reset, check the owners manual on how to reset the oil change light.... -
