Hill Descent button

I tried the hill descent button today going down my driveway in 16" of snow, and then again going down a steep hill near my home, and both times the button would blink and then go out. Does the hill descent function only work when in tow mode? or 4-low?

The Hill Start Assist system assists the driver when starting a vehicle from a stop on a hill.
The Hill Descent Control system maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD HIGH range and 4WD LOW range.

from the owners manual:


Hill Descent Control (HDC) — Four-Wheel Drive
Models With MP3023 Two-Speed Transfer Case Only HDC maintains vehicle speed while descending hills during off-road driving situations and is available in 4WD LOW range only. To enable HDC, press the HDC switch or put the Selec-Terrain™ system in "ROCK" mode ("ROCK" mode is only available in 4WD LOW range).

I had the same problem as you where the button would blink then go out. I read the manual and I too interpreted the AWD HIGH range as meaning I could just press the button and down the hill I went. I guess not. Gotta put it on low and then descend. Not quite what the manual said.
