My '18 was due for oil change at 9,430 miles. I just had it done this morning. 5.5 quarts of 0w20. I did not get an indicator message, I just old schooled it and changed at the window sticker indicated interval. So, what do I do when/if the service message appears? There are two reset procedures floating around in this and other forums. The first is "press the run button without starting the engine, press the accelerator down three times slowly within 30 seconds and press the run button again to turn off . The second is to press the run button without turning on the engine and pressing and holding down the accelerator for 30 seconds, take foot of the accelerator and then tap the brake pedal and turn off the run buttong. So, what the heck do I do? what procedure do I follow? If I change the oil before the service message appears do I reset anyway? Yikes, a little help or clarification from my learned colleagues please.
