Maintaince required on toyotas means you need oil change at 5000 miles. If you change oil yourself then you push start button go to odometer button. Hold odometer button down, and push the start button again. Don’t start the vehicle. Keep holding odometer button and 6 little lines will appear keep holding odometer button down until all the lines are gone. You’ve now reset oil/maintaince button for another 5000 miles. Good luck
