    I would like to get the Auto feature. I believe the LE has all the needed sensors?

    Thank you.

    The Electrical Wiring Diagram (more info) shows that the AUTO and DRL switch positions are electrically the same. The functionality depends on programming in the Main Body ECU (Multiplex Network Body Computer), and I’m not sure what else might happen if you replaced that ECU with one from a different grade.
