As some of you may know, I have a 97 Terrano (pathfinder) on the way. When I was going through the photos i noticed that there is a 2wd, auto, lock dial on the dash board. There is a also a floor shifter that enables the driver to put the vehicle into 2wd, 4wd-H and 4wd-L. So I am curious as to how to properly use this system without damaging any components. I dont have an owners manual for this particular vehicle, but if someone does, it would be nice to have a PDF copy of it! As far as I understand if this system is in auto mode, it basically pops the vehicle into 4wd when needed. What if the floor shifter is in the 2wd position but I have the dial on auto, i cant imagine the vehicle ever going into 4wd if the system detects slippage. What if the floor shifter is in 4wd-H but the dial is on 2wd? Does that mean that the vehicle is in 2wd, or 4wd no matter what? I cant seem to make sense of it at all. I would greatly appreciate if someone would be able to explain this to me. Ive been searching all over the web to no avail.
