Yes. If you don't wait until the oil life gets to 15% you will never see the maintenance codes so you'll have no idea what is due. Your MM will assume you did the maintenance and reset the codes that would have come up.
The simple answer to this problem is to follow the owner's manual. Which says to change your oil when the MM tells you to. And do whatever other maintenance comes up at that time. This is so simple but there are plenty of debates on DA on when to do this, that or the other maintenance.
And in the interest of full disclosure, there is a method you can use to see maintenance codes for upcoming maintenance without having to wait for the oil life to get to 15%. If you follow the MM reset procedure but stop one step short of actually resetting it, at step 3 you will see the codes that will show up the next time the oil life gets to 15%. If you then proceed to step 4 (Press the Select/Reset knob for 5 seconds), you will reset the oil life and the other MM codes.
Here's the reset procedure straight out of the owners manual:
1. Turn the ignition switch to ON.
2. Display the engine oil life by repeatedly pressing the Select/Reset knob.
3. Press and hold the knob for ten seconds or more. (The engine oil life indicator and the maintenance item codes blink.)
4. Press the Select/Reset knob for 5 seconds or more.
