WARNING!(Continued)
vehicle modification or poor vehicle maintenance
that reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.
ESC Operation Modes
To disable ESC and other safety systems, follow the instruc-
tion below.
There are three modes of active safety systems present on
the vehicle:
•ESC On
• Partial Off
• Full Off ESC On – Two Wheel Drive Vehicles And Four Wheel
Drive Vehicles In 2WD And 4WD High Range
This is the normal operating mode for ESC when operating
a two-wheel drive vehicle. It is also the normal mode for
operating a four-wheel drive vehicle in 2WD or 4WD
HIGH range. The ESC system will be in “ESC On” mode
whenever the vehicle is started or the power transfer unit
(if equipped) is shifted out of 4WD LOW range. This mode
should be used for most driving situations. ESC should
only be turned to “Partial Off” or “Full Off” for specific
reasons as noted. Refer to “Partial Off” and to “Full Off” for
additional information.
NOTE:
It is recommended to select the mode Partial Off
or Full Off only for specific reasons.5
SAFETY 173
Partial Off – Two Wheel Drive Vehicles And Four Wheel
Drive Vehicles In 2WD And 4WD High Range
The “Partial Off” mode is intended for driving in deep
snow, sand, or gravel. This mode raises the threshold for
TCS and ESC activation, which allows for more wheel spin
than what ESC normally allows.
To enter the “Partial Off” mode, momentarily push the
“ESC Off” button and the ESC Off indicator light will
illuminate. To turn the ESC on again, momentarily pushthe ESC OFF button and the ESC Off indicator light will
turn off. This will restore the normal “ESC On” mode of
operation.
NOTE:
To improve the vehicle’s traction when driving
with snow chains, or when starting off in deep snow, sand,
or gravel, it may be desirable to switch to the “Partial Off”
mode by momentarily pushing the “ESC Off” button. Once
the situation requiring “Partial Off” mode is overcome,
turn ESC back on by momentarily pushing the “ESC Off”
button. This may be done while the vehicle is in motion.
WARNING!
• When in “Partial Off” mode, the TCS functionality
of ESC, (except for the limited slip feature described
in the TCS section), has been disabled and the “ESC
Off Indicator Light” will be illuminated. When in
“Partial Off” mode, the engine power reduction
feature of TCS is disabled, and the enhanced vehicle
stability offered by the ESC system is reduced.
• Trailer Sway control (TSC) is disabled when the ESC
system is in the “Partial Off” mode.
ESC OFF Button
174 SAFETY
Full Off – Four-Wheel Drive Vehicles In 4WD High And
4WD Low Range
The “Full Off” mode is intended for off-highway and
off-road use when ESC stability features could inhibit
vehicle maneuverability due to trail conditions. The “ESC
Off” button is located in the lower switch bank above the
climate control panel. To enter “Full Off” mode, push and
hold the “ESC Off” button for five seconds while the
vehicle is stopped with the engine running. After five
seconds, the ESC Off indicator light will illuminate and an
“ESC Off” message will appear in the odometer.
In this mode, ESC and TCS are turned off (except for the
“limited slip” feature described in the TCS section) until
the vehicle reaches a speed of 40 mph (64 km/h). At speeds
over 40 mph (64 km/h), the system automatically switches
to “Partial Off” mode, described above. When the vehicle
speed returns to less than 35 mph (56 km/h), the ESC
system will return to “Full Off” mode. The ESC OFF
indicator light is always illuminated when ESC is off. To
turn ESC on again, momentarily push the “ESC Off”
button. This will restore the normal “ESC On” mode of
operation.NOTE:
With the ESC switched off, the enhanced vehicle
stability offered by ESC is unavailable. In an emergency
evasive maneuver, the ESC system will not engage to assist
in maintaining stability. “Full Off” mode is only intended
for off-highway or off-road use.
NOTE:
• “Full Off” is the only operating mode for ESC in 4WD
LOW range. The ESC system will be in this mode
whenever the vehicle is started in 4WD LOW range or
the power transfer unit is shifted into 4WD LOW range.
• The “ESC OFF” message will display and a chime will
sound when the gear selector is moved from any posi-
tion to the PARK position and then moved out of the
PARK position. This will occur even if the message was
cleared previously.
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 performance in
specific modes.
Partial or full off of the active safety systems will be
indicated by a light in the instrument cluster.

SAFETY 175
InSAND andMUD, 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 ESC button.
NOTE: In 4WD LOW, the active safety systems are com-
pletely 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 run-
ning. If the “ESC Activation/Malfunction Indicator Light”
comes on continuously with the engine running, a mal-
function 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 authorized 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 flashes
when Traction Control System 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.
NOTE:
•
The “ESC Activation/Malfunction Indicator Light” and
the “ESC OFF Indicator Light” come on momentarily
each time the ignition switch is turned ON.
• Each time the ignition is turned ON, 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.
TheESC OFF Indicator Light indicates the
Electronic Stability Control (ESC) is partially off
or full off.
The ESC OFF switch is located in the center console.
176 SAFETY
Dynamic Steering Torque (DST)
The DST function uses the integration of the ESC system
with the electric power steering to increase the safety level
of the whole car. In critical situations (understeering,
oversteering, braking with different grip conditions),
through the DST function the ESC system controls the
steering to implement an additional torque contribution on
the steering wheel, to suggest the most correct maneuver 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.
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).
Hill Descent Control (Trailhawk)
178 SAFETY
2. Enabled (feature is enabled and ready but activationconditions are not met, or driver is actively overriding
with brake or throttle application).
3. Active (feature is enabled and actively controlling ve- hicle 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 ’s 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 magnitude
(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 ’s door opens.

SAFETY 179
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.
• The active braking is enabled only if the front seat belts
are fastened.
• The active braking is disabled when a trailer is con-
nected with a Mopar Trailer Towing system. If the vehicle is equipped with an aftermarket system, it is
recommended that the Active Braking is turned off
manually.
WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect every
type of potential collision. The driver has the respon-
sibility to avoid a collision by controlling the vehicle
via braking and steering. Failure to follow this warn-
ing could lead to serious injury or death.
Turning FCW On Or Off
The Forward Collision menu setting is located in the
Uconnect settings.
NOTE:
The default status of FCW is “Warning + Active
Braking,” this allows the system to warn you of a possible
collision with the vehicle in front of you and enable the
active braking.
• Changing the FCW status to “off” deactivates the sys-
tem, so no warning or active braking will be available in
case of a possible collision
