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 De-

scent 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.
