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.

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.

Electronic Roll Mitigation (ERM)
This system anticipates the potential for wheel lift by
monitoring the driver ’s steering wheel input and the speed
of the vehicle. When ERM determines that the rate of
change of the steering wheel angle and vehicle’s speed are
sufficient to potentially cause wheel lift, it then applies the
appropriate brake and may also reduce engine power to
lessen the chance that wheel lift will occur. ERM will only
intervene during very severe or evasive driving maneu-
vers. ERM can only reduce the chance of wheel lift occur-
ring during severe or evasive driving maneuvers. It cannot
prevent wheel lift due to other factors, such as road
conditions, leaving the roadway, or striking objects or other
vehicles.
NOTE:ERM is disabled anytime the ESC is in “Full Off”
mode. Refer to Electronic Stability Control (ESC) in this
section for a complete explanation of the available ESC
modes.
WARNING!
Many factors, such as vehicle loading, road conditions,
and driving conditions, influence the chance that
(Continued)
WARNING! (Continued)
wheel lift or rollover may occur. Electronic Roll Miti-
gation (ERM) cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway or
striking objects or other vehicles. The capabilities of an
ERM-equipped vehicle must never be exploited in a
reckless or dangerous manner, which could jeopardize
the user’s safety or the safety of others.
Traction Control System (TCS)
This system monitors the amount of wheel spin of each of
the driven wheels. If wheel spin is detected, brake pressure
is applied to the slipping wheel(s) and engine power is
reduced to provide enhanced acceleration and stability. A
feature of the TCS system, Brake Limited Differential
(BLD), functions similar to a limited slip differential and
controls the wheel spin across a driven axle. If one wheel
on a driven axle is spinning faster than the other, the
system will apply the brake of the spinning wheel. This
will allow more engine torque to be applied to the wheel
that is not spinning. This feature remains active even if TCS
and ESC are in the “Partial Off” mode or the “Full Off”
mode. Refer to “Electronic Stability Control (ESC)” in this
section for further information.

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
Page 181 of 516

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.
5
SAFETY 179
Page 182 of 516

•The vehicle is driven greater than 25 mph (40 km/h)
(HDC exits immediately.)
Feedback To The Driver:
The instrument cluster has an HDC icon and the HDC
switch has an LED which offer feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate and
remain solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The switch lamp will flash for several seconds then
extinguish when the driver pushes the HDC switch
when enable conditions have not been met.
The Hill Descent Switch is located within the Selec-Terrain
knob in the upper right position.
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is re-
sponsible for maintaining a safe vehicle speed.
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two radar-
based sensors, located inside the rear bumper fascia, to
detect highway licensable vehicles (automobiles, trucks,
motorcycles, etc.) that enter the blind spot zones from the
rear/front/side of the vehicle.
When the vehicle is started, the BSM warning light will
momentarily illuminate in both outside rear view mirrors
to let the driver know that the system is operational. The
Rear Detection Zones
180 SAFETY
Page 183 of 516

BSM system sensors operate when the vehicle is in any
forward gear or REVERSE and enters stand-by mode when
the vehicle is in PARK.
The BSM detection zone covers approximately one lane
width on both sides of the vehicle, 10 ft (3 m). The zone
length starts at the outside mirror and extends approxi-
mately 20 ft (6 m) beyond the rear bumper of the vehicle.
The BSM system monitors the detection zones on both
sides of the vehicle when the vehicle speed reaches ap-
proximately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.
NOTE:
•The BSM system does NOT alert the driver about
rapidly approaching vehicles that are outside the detec-
tion zones.
• If a trailer is connected to the vehicle, it is necessary to
deactivate BSM system manually by settings menu to
avoid a misdetection. Refer to “Uconnect Settings” in
“Multimedia” for further information. The area on the rear fascia where the radar sensors are
located must remain free of snow, ice, and dirt/road
contamination so that the BSM system can function prop-
erly. Do not block the radar sensors located on the rear
fascia with foreign objects (bumper stickers, bicycle racks,
etc.).

The BSM system notifies the driver of objects in the
detection zones by illuminating the BSM warning light
located in the outside mirrors in addition to sounding an
audible (chime) alert and reducing the radio volume. Refer
to “Modes Of Operation” for further information.The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries.
