4x4 Question

[lowerider4]

I couldn't find a topic on this so sorry if there already is one but I have a question. This is my first Jeep I've ever owned and I'm curious about the 4x4 setting. I don't see an option to lock it in 4x4. If I would change from auto to either Snow, Sand, Rock does that lock in the 4X4?

It's full-time 4wd/AWD.

ok thanks, I wasn't sure on the Overland because I didn't see where it said full time 4wd. I know the limiteds it did but wasn't sure if there was something different with the Overland.
