Hill Descent Control (HDC) – Four-Wheel Drive
Models With NV245 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 (transfer case
must be in 4WD LOW range), press the HDC switch. If
the HDC switch is pressed when the vehicle is not in
4WD LOW range, the light in the switch will flash for five
seconds and HDC will not be enabled.
Hill Descent Switch
When HDC is properly enabled, the message "HILL
DESCENT CONTROL" will appear in the EVIC and the
light in the switch will be illuminated. HDC will auto-
matically apply the brakes to control downhill speed
when necessary. HDC has the capability to sense terrain
and will only activate when the vehicle is descending a
hill. It will usually not activate on level ground.
