06 GV 4wd/2wd Question???

Hi all, I am new here and this is my first post, I am in Australia and have the 06 Grand Vitara (in Oz spec).
I am trying to find info on the tranfer case setup.
Is it possible to have the option to change between 2wd and 4wd? Over here all the GV's are 4wd only and I can't find anyone who can tell me about the 2wd/4wd thing. The only options my selector gives me is 4H 4H-lock 4L-lock or N. What I would like is to have say 2H 4H-lock and 4L-lock or something close to that.
Any help will be much appreciated as I can't find info here.

Cheers
