That button on the bottom raises or lowers the rear if you have the Adventure Package or the Air Suspension package. I have the Adventure Package on my '06 and to be honest, I've only used that button once. In a previous post someone raised the rear with that button and then drove into his garage and got the garage door with his roof racks. I can't find it in the owners manual but I believe it raises the rear 2 and half inches.
The adventure package on the 2009 H3 includes front and rear lockers on any model. You can use the front and or rear lock at your choosing because of the switches are seperate buttons.
You can't get rear locking by its self starting in 2009 on the H3. Either both or nothing.
