Sorry, but I cannot believe the number of questions about this that have been coming up lately. Ian has even created a "transfer case shifting 101" thread on XOC in response.
As for having my OM in front of me, I don't. I'm just familiar with the proper operation of my Xterra and I have retained some of the the information in my OM, especially since it keeps coming up it's hard to get rusty.
