When TSC is functioning, the “ESC Activation/
Malfunction Indicator Light” will flash, the engine power
may be reduced and you may feel the brakes being applied
to individual wheels to attempt to stop the trailer from
swaying. TSC is disabled when the ESC system is in the
“Partial Off” or “Full Off” modes.
WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.
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.
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 apply-
ing 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.
