It's like that, by design.
You can shift from 2 Hi to 4 Hi, and vice-versa, while moving. I remember the manual stating you can do this up to 55 mph, and I've done so.
If you're in 2 Hi, just push the "hi" button in -- it stays in and the transfer case shifts to 4 Hi. If you're in 4 Hi, just push the "hi" button again -- it pops out and the transfer case shifts to 2 Hi.
To shift to 4 Lo, you must already be in 4 Hi. Stop moving, put the gear shift in neutral, and press "lo" -- the button doesn't stay in, but the transfer case shifts to 4 Lo. If you're in 4 Lo, stop moving, put the gear shift in neutral, and press "lo" -- the button doesn't stay in, but the transfer case shifts to 4 Hi.
Why doesn't the "lo" button stay in?
Because you can shift from 4 Lo directly to 2 Hi. If you're in 4 Lo, stop moving, put the gear shift in neutral, and press "hi". The botton pops out and the transfer case shifts from 4 Lo to 2 Hi. If the "lo" button stayed in, this wouldn't work, but people would try to do it anyway.
Why does the "hi" button stay in?
Beats me.
