My 05 corolla has a "maintenance required" light that has come on on the right side of my dash. I have taken care of the car and changed the oil every 3000 miles. I have changed the oil myself though so i dont have to pay 30 dollars for 8 dollars worth of oil. I'm thinking this light is just some programmed reminder, but if anybody knows what this light is and how i can turn it off please let me know. Thank you.
