Yup, must be in 4L, then press the button to engage the system. If you start down an incline in 4L with HDC on, the Jeep will brake individual tires to maintain Xmph based on your current gear. You'll have to read the manual to see the actual speeds, but it's close to:
1st = 1mph
2nd = 2.5mph
3rd = 4mph
etc
Some people don't like HDC, and think it's too much of a nanny. Personally, I like knowing that it's there. I prefer to brake myself when crawling down a hill, but I know that if my foot were to slip off the pedal the Jeep wouldn't get away from me.
In my testing, I've also found the following undocumented features:
- If the system is actively slowing the Jeep and you accidentally press the HDC button, HDC will not disengage until you reach flat ground.
- If the system is actively slowing the Jeep and you accidentally knock the shifter into N, HDC will bring the Jeep to a complete stop.
A little extra peace of mind can't hurt.

In reality, the system isn't going to do anything that your foot wouldn't do. Brake like crazy, let off to avoid slippage, repeat. Of course, HDC can brake individual wheels, using the most grippy tires for the job. I suspect, though, that if the hill is steep enough that your tires can no longer grab, who's managing the brakes is kinda irrelevant.

I recently used my GDC and it worked great.
We did a trail up a mountain side and if course what goes up must come down. I was worried about overheating or riding the breaks all the way down.
I have an auto and it worked great. It kept it slow at steep inclines close to the cliffs edge and it kept it slow and controlled the whole time.
I covered the break the whole time but rarely had to actually press it. When the terrain leveled a bit I just used the gas and it allowed me to speed up.
As soon as I let of the gas it would bring it back to the gears speed threshold. Great feature.
