Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driving while in
4WD Low Range. 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:
•Driveline is in 4WD Low Range.
•Vehicle speed is below 7.5 mph (12 km/h).
•Electric Park Brake (EPB) is released.
•Driver door is closed.

Activating HDC
Once HDC is enabled, it will activate automatically if
driven down a grade of sufficient magnitude (greater
than approximately 8%). The set speed for HDC is
selectable by the driver and can be adjusted using brake
and throttle input.
Driver Override:
The driver may override HDC activation with throttle or
brake application at anytime.
Deactivating HDC
HDC will be deactivated but remain available if any of
the following conditions occur:
•Driver overrides HDC set speed with throttle or brake
application.
•Vehicle speed exceeds 7.5 mph (12 km/h) but remains
below 25 mph (40 km/h).
•Vehicle is on a downhill grade of insufficient magni-
tude (less than approximately 8%), is on level ground,
or is on an uphill grade.
•Vehicle is shifted to PARK.
Disabling HDC
HDC will be deactivated and disabled if any of the
following conditions occur:
•The driver pushes the HDC switch.
•The driveline is shifted out of 4WD Low Range.
•Driver door opens.
•The vehicle is driven greater than 25 mph (40 km/h)
(HDC exits immediately.)

Selec-Terrain™ — If Equipped
On models equipped with Selec-Terrain™, the activation
of some driving modes provide partial off or full off of
some active safety systems in order to optimize perfor-
mance in specific modes.
Partial or full off of the active safety systems will be
indicated by a light in the instrument cluster.
In#SAND#and#MUD#the active safety systems are
partially disabled and put in place to ensure maximum
performance in the specific mode of operation. However,
you can reactivate them completely at any time by
pushing the button.
NOTE:In 4WD LOW, the active safety systems are
completely bypassed in order to ensure maximum off-
road performance.
ESC Activation/Malfunction Indicator Light And
ESC OFF Indicator Light
The “ESC Activation/Malfunction Indicator
Light” in the instrument cluster will come on
when the ignition switch is turned to the ON
position. It should go out with the engine
running. If the “ESC Activation/Malfunction Indicator
Light” comes on continuously with the engine running, a
malfunction has been detected in the ESC system. If this
light remains on after several ignition cycles, and the
vehicle has been driven several miles/kilometers at
speeds greater than 30 mph (48 km/h), see your autho-
rized dealer as soon as possible to have the problem
diagnosed and corrected.
The “ESC Activation/Malfunction Indicator Light” (lo-
cated in the instrument cluster) starts to flash as soon as
the tires lose traction and the ESC system becomes active.
The “ESC Activation/Malfunction Indicator Light” also

on the steering wheel, to suggest the most correct ma-
neuver to the driver. The coordinated action of brakes
and steering increases the safety and car control feeling.
NOTE:The DST is a driving aid system and does not
replace the driver ’s actions while driving the car.
Selec Speed Control (SSC) — If Equipped
SSC is intended for off road driving in 4WD Low Range
only. SSC maintains vehicle speed by actively controlling
engine torque and brakes.
SSC 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 SSC
SSC is enabled by pressing the SSC switch, but the
following conditions must also be met to enable SSC:
•Driveline is in 4WD Low Range
•Vehicle speed is below 5 mph (8 km/h)
•Parking brake is released
•Driver door is closed
•Driver is not applying throttle
Activating SSC
Once SSC is enabled it will activate automatically once
the following conditions are met:
•Driver releases throttle
•Driver releases brake

Driver Override:
The driver may override SSC activation with throttle or
brake application at any time.
Deactivating SSC
SSC will be deactivated but remain available if any of the
following conditions occur:
•Driver overrides SSC set speed with throttle or brake
application.
•Vehicle speed exceeds 20 mph (32 km/h) but remains
below 40 mph (64 km/h).
•Vehicle is shifted to park.
Disabling SSC
SSC will deactivate and be disabled if any of the follow-
ing conditions occur:
•The driver presses the SSC switch.
•The driveline is shifted out of 4WD Low Range.
•The parking brake is applied.
•Driver door opens.
•The vehicle is driven greater than 20 mph (32 km/h)
for greater than 70 seconds.
•The vehicle is driven greater than 40 mph (64 km/h)
(SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and the SSC
switch has an LED which offer feedback to the driver
about the state SSC is in.
•The cluster icon and switch lamp will illuminate and
remain on solid when SSC is enabled or activated. This
is the normal operating condition for SSC.

When the system determines a collision with the vehicle
in front of you is no longer probable, the warning
message will be deactivated.
NOTE:
•The minimum speed for FCW activation is 4 mph
(7 km/h).
•The maximum speed for FCW activation is 124 mph
(200 km/h).
•The FCW alerts may be triggered on objects other than
vehicles such as guard rails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
•The FCW system is intended for on-road use only. If
the vehicle is taken off-road, the FCW system should
be deactivated to prevent unnecessary warnings to the
surroundings.
•If the vehicle enters 4WD Low Range, the FCW system
will be automatically deactivated.
