on the dash there should be three buttons info, setup and reset one of those you press a few times and should show reset oil

First turn the key to the run position (dash lights on and gauges on) you do not have to start the car. Now look for the "info" button. Push the info button until you see "push set for system check". Then push the "set" button After you push "set" you will see the oil life setting. Mine was at 0% life remaining. Now push the "set" button for 5 to 10 seconds until you hear a beep. Then the oil life will show 100%. Start the car and the oil change warning should be off. If not just retry the procedure. Where i made my mistake was in not holding the set button down long enough. Both the info and set button are in the center of the dash near the radio.
