Gear Approximate HDC Set Speed
1st 1 mph (1.5 km/h)
2nd 2.5 mph (4 km/h)
3rd 4 mph (6.5 km/h)
4th 5.5 mph (9 km/h)
DRIVE 7.5 mph (12 km/h)
REVERSE 1 mph (1.5 km/h)
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.
Enabling HDC
1. Shift the transfer case into 4WD LOW range. Refer to
“Four-Wheel Drive Operation” in “Starting and Oper-
ating” for further information.
2. Push 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.
If the ESC senses that the brakes are overheating the
“Hill Descent Control Indicator Light” will flash for
five seconds and HDC will become deactivated until
the brakes have cooled.
Disabling HDC
Push 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.
