How do I reset the maintenance required light after changing the oil in the 2006 Corolla?

This is something the dealer can do for you.

For the 2006 Corolla, first make sure display is in ODO (not TRIP A or B). Turn ignition to LOCK. Press and hold the trip reset button. Turn ignition to ON (do not start engine) and watch the dashes count down until it displays 000000. Release the reset button and you are done.

Thanks was very helpful.
