If i remember correctly. Turn the ignition on but don't start the engine. Press the menu button on the turn signal stalk till oil life is displayed. Press and hold the set/clear button on the end of the t/sig stalk till the oil life reads 100%.
I was at a stop light after I changed my oil and as long as ur at 0mph/kph you can just go to oil life and press and hold te button for 10 seconds it'll beep once keep holding it and it'll go up to 100%
