with the power on and the car not running in your drivers information center you will find the oil life monitor press and hold the enter key. it will have a check mark or a arrow like the enter key on your keyboard then you are done, or read your owners manual for this information like most or the answers to programming questions in here.
Turn the key on without starting the engine. Wait until all the lights on the dash are set, then pump the gas slowly 3 times. Your change oil light should flash. Anyway, that is how my vehicles work if they haven't changed it,.
