There is a procedure for resetting the lamp. The lamp is purely mileage based and will come on every 3000 miles. Try this:
Sit in your Chrysler Sebring's driver-side seat. Put the key in, and then turn it to "On/Run." Starting the engine is not required.
Push the accelerator pedal to the floor three times; be sure to do this fairly quickly (within 10 seconds).
Turn the key to "Lock" and remove it. Re-insert it, and then start the engine. Verify that the oil message is gone.
