I was poking around the Honda site and decided to check out the Pilot section. There is a good demo (a mix of silent Quicktime and Flash animation w/narration) of the VTM-4 system. Here is the url:

I guess we can assume that the Ridgeline will use this identical system or something very similar.
The demo mentions a user activated rear differential locker.
