Axxis is correct: to reset the "Maint Req" light in the 2009 Corolla, the TRIP A odometer must be chosen before turning the key off. Then depress the trip odometer button and hold it before and after turning the key back on (but not starting the motor).
With the trip odometer button still pressed, a series of dashes will appear, followed by several zeroes. The Maint Req light will now be off.
-our '05 Camry requires the main odometer to be selected
-our '03 Corolla necessitates momentary disconnection of the battery ground
