4 wheel drive

I believe this has the lever like my wife's 2007 Liberty.  You can pull back the lever to whichever 4WD option you want, at anywhere up to 55 mph.  Same deal if it has electronic 4WD, you simply turn the knob to the 4WD setting you want.

I would suggest always putting the transmission in neutral before putting the transfer case in 4x4. ALWAYS put it in neutral before going to low range. Pull the lever back.
