First go to an Auto parts store that will allow you to sign out a ODB Tester and run the code program to see what codes you have. Write them down!
Secondly , try this to extinguish the Maintenance Required light:
(Also covered in your Ref. Owner's Manual pages 67-68)
To reset the light press and hold down the odometer button as you turn "on" your car (you do not need to run your car - just turn it to the "on" position) and leave it pressed for about 20 seconds. Release and your light will go out.
Done deal.
