I imagine the auto 4 works the same way as the auto 4 on the Chevy's and Rams. Senses wheel slip and provides power to the non slipping tires.

Yea I am thinking it is typical traction control that uses the brakes to limit wheel spin. I am sure it sorta works but I think I far prefer upgraded differential systems to transfer torque.
