My Daughter just got a low mile 2015 Jeep Compass, 4WD I believe it has the 2.4L and 6spd Automatic and 4WD. It has a 4WD Lock T lever. I advised her not to ever engage the 4 wheel lock on dry pavement. As best I understand it, it will lock the differential between the front/rear axles and make the system part time 4WD, i.e. 4X4; and all know what that means for turns on dry pavement. I can't seem to find much info on this Freedom Drive, its only marketing terms, dumb down stuff just making big claims. Some contradictory information, some saying its FWD and implying engaging the 4WD lock just engages the rear axle to make it full time 4WD. And then other sources claim its FWD or automatically switches to full time 4WD, and implies the 4WD lock mode changes it to part time 4WD. I looked at a PDF of the Owners Manual and there is no warning about 4WD Lock and not engaging it on dry pavement. So whats the deal? Does engaging 4WD Lock actually locks the center differential, make it part time 4WD and thus should never be driven on dry pavement in those conditions? Does the system switch back and forth between FWD and 4WD during normal driving? If it does, is it electronically controlled to do so with the ECC? Or is it merely a reaction from applying brakes to limit wheel slip, results in directing power to the rear axle. There is a Power Transfer unit attached to the starboard side of transmission output. It has at least a ring and pinion to a 2 segment driveshaft to an Electronic Controlled Coupling unit, then too the rear differential. So I guess, the key to understanding this, is just exactly does this rear electronically controlled coupling do?
