250 SAFETY
The ESC Activation/Malfunction Indicator Light
starts to flash as soon as the tires lose traction and
the ESC system becomes active. The ESC Activation/
Malfunction Indicator Light also flashes when TCS is
active. If the ESC Activation/Malfunction Indicator
Light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving to
the prevailing road conditions.
The ESC OFF Indicator Light indicates the
customer has elected to have the Electronic
Stability Control (ESC) in a reduced mode.
NOTE:
The ESC Activation/Malfunction Indicator Light

and the ESC OFF Indicator Light come on
momentarily each time the ignition is placed in
the ON/RUN mode.
Each time the ignition is placed in the ON/RUN

mode, the ESC system will be on even if it was
turned off previously.
The ESC system will make buzzing or clicking

sounds when it is active. This is normal; the
sounds will stop when ESC becomes inactive
following the maneuver that caused the ESC
activation.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off-road
driving while in 4WD Low. HDC maintains
vehicle speed while descending hills
during various driving situations. HDC
controls vehicle speed by actively controlling the
brakes.
HDC Has Three States:
1. Off (feature is not enabled and will not
activate).
2. Enabled (feature is enabled and ready but
activation conditions are not met, or driver is
actively overriding with brake or throttle
application).
3. Active (feature is enabled and actively
controlling vehicle speed).
Enabling HDC
HDC is enabled by pushing the HDC switch, but the
following conditions must also be met to enable
HDC:
The driveline is in 4WD Low.

The vehicle speed is below 5 mph (8 km/h).

The parking brake is released.

The driver door is closed.

Activating HDC
Once HDC is enabled it will activate automatically
if driven down a grade of sufficient magnitude.
The set speed for HDC is selectable by the driver,
and can be adjusted by using the gear shift +/-.
The following summarizes the HDC set speeds:
