Hill Descent Control IS in the Owner's Manual (the one that is on the DVD, not in the User's Guide which is provided in print form at purchase). Here is what it says:

Hill Descent Control (HDC) – If Equipped
HDC is only intended for low speed off-road driving. HDC maintains vehicle speed while descending hills in off-road driving conditions by applying the brakes when necessary.
The symbol indicates the status of the Hill Descent Control (HDC) feature. The lamp will be on solid when HDC is armed. HDC can only be armed when the transfer case is in the “4WD LOW” position and the vehicle speed is less then 30 mph (48 km/h). If these conditions are not met while attempting to use the HDC feature, the HDC indicator light will flash on/off.
When enabled, HDC senses the terrain and activates when the vehicle is descending a hill. HDC speed may be adjusted by the driver to suit the driving conditions. The speed corresponds to the transmission gear selected.
However, the driver can override HDC operation by applying the brake to slow the vehicle down below the HDC control speed. If more speed is desired during HDC control, the accelerator pedal will increase vehicle speed in the usual manner. When either the brake or the accelerator is released, HDC will control the vehicle at the original set speed.
Shift the transfer case into 4WD LOW range. Refer to “Four-Wheel Drive Operation” in “Starting and Operating” for further information.
Press the “Hill Descent” button. The “Hill Descent Control Indicator Light” in the instrument cluster will turn on solid.
Note: If the transfer case is not in 4WD LOW range, the “Hill Descent Control Indicator Light” will flash for five seconds and HDC will not be enabled.
Press the “Hill Descent” button or shift the transfer case out of 4WD LOW range. The “Hill Descent Control Indicator” light in the instrument cluster will turn off.

Hate to bring this back up but one question about operation during HD, when its engaged, going downhill, and going slowly, if I apply slightly more braking, I get the feel of the antiskid working through the brake pedal, and the sound of anti skid like a rumble sound, is this normal?
I have a 2013 sport and I'm pretty sure I don't have this feature. The only button I have is the esc button. Am I missing the location of the button?
My 2013 JKU Sport has this feature. It may have to have an automatic transmission to have this feature. On the bill of sale from my dealer this feature is listed as a sub-item of 5-Speed automatic transmission.
