— Low Washer Fluid Warning Light —
If Equipped
This warning light will illuminate when the
windshield washer fluid is low.
— Engine Check/Malfunction Indica-
tor Warning Light (MIL)
The Engine Check/Malfunction Indicator
Light (MIL) is a part of an Onboard Diagnostic
System called OBD II that monitors engine
and automatic transmission control systems.
This warning light will illuminate when the
ignition is in the ON/RUN position before
engine start. If the bulb does not come on
when turning the ignition switch from OFF to
ON/RUN, have the condition checked
promptly.
Certain conditions, such as a loose or missing
gas cap, poor quality fuel, etc., may illumi-
nate the light after engine start. The vehicle
should be serviced if the light stays on
through several typical driving styles. In most
situations, the vehicle will drive normally and
will not require towing.When the engine is running, the MIL may
flash to alert serious conditions that could
lead to immediate loss of power or severe
catalytic converter damage. The vehicle
should be serviced by an authorized dealer as
soon as possible if this occurs.WARNING!
A malfunctioning catalytic converter, as
referenced above, can reach higher tem-
peratures than in normal operating condi-
tions. This can cause a fire if you drive
slowly or park over flammable substances
such as dry plants, wood, cardboard, etc.
This could result in death or serious injury
to the driver, occupants or others.
CAUTION!
Prolonged driving with the Malfunction
Indicator Light (MIL) on could cause dam-
age to the vehicle control system. It also
could affect fuel economy and driveability.
If the MIL is flashing, severe catalytic
converter damage and power loss will soon
occur. Immediate service is required.
— AdBlue® (UREA) Injection System
Failure Warning Light — If Equipped
This warning light will illuminate along with a
dedicated message on the display (If
Equipped) if an unknown fluid not conform-
ing with acceptable characteristics is in-
serted, or if an average consumption of
AdBlue
®(UREA) over 50% is detected. Con-
tact an authorized dealer as soon as possible.
If the problem is not solved, a specific mes-
sage will appear on the Instrument Cluster
Display whenever a certain threshold is
reached until it will no longer be possible to
start the engine.
When about 125 mi (200 km) are remaining
before the AdBlue
®tank is empty, a continu-
ous dedicated message will appear on the
instrument panel, accompanied by a buzzer
sound (If Equipped).
SERV4WD— Service 4WD Warning Light — If
Equipped
This warning light will illuminate to signal a
fault with the 4WD system. If the light stays
on or comes on during driving, it means that
the 4WD system is not functioning properlyGETTING TO KNOW YOUR INSTRUMENT PANEL

hicle start-ups as long as the malfunction
exists. When the malfunction indicator is
illuminated, the system may not be able to
detect or signal low tire pressure as intended.
TPMS malfunctions may occur for a variety of
reasons, including the installation of replace-
ment or alternate tires or wheels on the ve-
hicle that prevent the TPMS from functioning
properly. Always check the TPMS malfunc-
tion telltale after replacing one or more tires
or wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
CAUTION!
The TPMS has been optimized for the
original equipment tires and wheels.
TPMS pressures and warning have been
established for the tire size equipped on
your vehicle. Undesirable system opera-
tion or sensor damage may result when
using replacement equipment that is not
of the same size, type, and/or style. After-
market wheels can cause sensor damage.
Using aftermarket tire sealants may cause
CAUTION!
the Tire Pressure Monitoring System
(TPMS) sensor to become inoperable. Af-
ter using an aftermarket tire sealant it is
recommended that you take your vehicle
to your authorized dealer to have your
sensor function checked.
The system only warns the tire pressure is
low: it is not able to inflate them.

Dynamic Steering Torque (DST)
Dynamic Steering Torque is a feature of the
ESC and Electric Power Steering (EPS) mod-
ules that provides torque at the steering
wheel for certain driving conditions in which
the ESC module is detecting vehicle instabil-
ity. The torque that the steering wheel re-
ceives is only meant to help the driver realize
optimal steering behavior in order to reach/
maintain vehicle stability. The only notifica-
tion the driver receives that the feature is
active is the torque applied to the steering
wheel.
NOTE:
The DST feature is only meant to help the
driver realize the correct course of action
through small torques on the steering wheel,
which means the effectiveness of the DST
feature is highly dependent on the driver’s
sensitivity and overall reaction to the applied
torque. It is very important to realize that this
feature will not steer the vehicle, meaning
the driver is still responsible for steering the
vehicle.
Hill Descent Control (HDC) — If Equipped
HDC is intended for low speed off road driv-
ing while in 4WD Low Range. HDC maintains
vehicle speed while descending hills during
various driving situations. HDC controls ve-
hicle 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 5 mph (8 km/h).
• Parking brake is released.
• Driver door is closed.Activating HDC
Once HDC is enabled it will activate auto-
matically if driven down a grade of sufficient
magnitude. The set speed for HDC is select-
able by the driver, and can be adjusted by
using the gear shift +/-. The following sum-
marizes the HDC set speeds:
HDC Target Set Speeds
• P = No set speed. HDC may be enabled but
will not activate.
• R = 0.6 mph (1 km/h)
• N = 1.2 mph (2 km/h)
• D = 0.6 mph (1 km/h)
• 1st = 0.6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)
• 8th = 5.0 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
SAFETY
94

NOTE:
During HDC the +/- shifter input is used for
HDC target speed selection, but will not af-
fect the gear chosen by the transmission.
When actively controlling HDC the transmis-
sion will shift appropriately for the driver-
selected set speed and corresponding driving
conditions.
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 20 mph (32 km/h)
but remains below 40 mph (64 km/h).
• Vehicle is on a downhill grade of insuffi-
cient magnitude, 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.
• 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) (HDC exits immediately).
• HDC detects excessive brake temperature.
Feedback To The Driver
The instrument cluster has an HDC icon and
the HDC switch has an LED icon, which offers
feedback to the driver about the state HDC is
in.
• The cluster icon and switch lamp will illu-
minate and remain on solid when HDC is
enabled or activated. This is the normal
operating condition for HDC.• The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the HDC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash
for several seconds then extinguish when
HDC disables due to excess speed.
• The cluster icon and switch lamp will flash
when HDC deactivates due to overheated
brakes. The flashing will stop and HDC will
activate again once the brakes have cooled
sufficiently.
WARNING!
HDC is only intended to assist the driver in
controlling vehicle speed when descend-
ing hills. The driver must remain attentive
to the driving conditions and is responsible
for maintaining a safe vehicle speed.
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.
95

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 pushing 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 automati-
cally once the following conditions are met:
• Driver releases throttle.
• Driver releases brake.
•
Transmission is in any selection other than P.
• Vehicle speed is below 20 mph (32 km/h).
The set speed for SSC is selectable by the
driver, and can be adjusted by using the gear
shift +/-. Additionally, the SSC set speed may
be reduced when climbing a grade and the
level of set speed reduction depends on the
magnitude of grade. The following summa-
rizes the SSC set speeds:
SSC Target Set Speeds
• 1st = .6 mph (1 km/h)
• 2nd = 1.2 mph (2 km/h)
• 3rd = 1.8 mph (3 km/h)
• 4th = 2.5 mph (4 km/h)
• 5th = 3.1 mph (5 km/h)
• 6th = 3.7 mph (6 km/h)
• 7th = 4.3 mph (7 km/h)• 8th = 5 mph (8 km/h)
• 9th = 5.6 mph (9 km/h) – If Equipped
• REVERSE = .6 mph (1 km/h)
• NEUTRAL = 1.2 mph (2 km/h)
• PARK = SSC remains enabled but not
active
NOTE:
• During SSC the +/- shifter input is used for
SSC target speed selection but will not
affect the gear chosen by the transmission.
While actively controlling SSC the trans-
mission will shift appropriately for the
driver-selected set speed and correspond-
ing driving conditions.
• SSC performance is influenced by the Ter-
rain Select mode. This difference may be
notable to the driver and may be perceived
as a varying level of aggressiveness.
Driver Override:
The driver may override SSC activation with
throttle or brake application at any time.
SAFETY
96

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 following conditions occur:
• The driver pushes 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 feed-
back to the driver about the state SSC is in.

SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must re-
main attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar sensors, located inside the
rear bumper fascia, to detect highway licens-
able vehicles (automobiles, trucks, motor-
cycles, etc.) that enter the blind spot zones
from the rear/front/side of the vehicle.
97

Forward Collision Warning (FCW) With
Mitigation
The Forward Collision Warning (FCW) with
Mitigation system provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a
brake jerk to warn the driver when it detects a
potential frontal collision. The warnings and
limited braking are intended to provide the
driver with enough time to react, avoid or
mitigate the potential collision.
NOTE:
FCW monitors the information from the for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-
tem determines that a forward collision is
probable, the driver will be provided with
audible and visual warnings and may provide
a brake jerk warning. If the driver does not
take action based upon these progressive
warnings, then the system will provide a lim-
ited level of active braking to help slow the
vehicle and mitigate the potential forward
collision. If the driver reacts to the warningsby braking and the system determines that
the driver intends to avoid the collision by
braking but has not applied sufficient brake
force, the system will compensate and pro-
vide additional brake force as required.
If a Forward Collision Warning with Mitigation
event begins at a speed below 26 mph
(42 km/h), the system may provide the maxi-
mum or partial braking to mitigate the poten-
tial forward collision. If the Forward Collision
Warning with Mitigation event stops the ve-
hicle completely, the system will hold the
vehicle at a standstill for two seconds and
then release the brakes.
W
hen 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
1 mph (2 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.• It is unsafe to test the FCW system. To
prevent such misuse of the system, after
four Active Braking events within an igni-
tion cycle, the Active Braking portion of
FCW will be deactivated until the next igni-
tion cycle.
• The FCW system is intended for on-road use
only. If the vehicle is taken off-road, the
FCW system should be deactivated to pre-
vent unnecessary warnings to the surround-
ings. If the vehicle enters 4WD Low Range
or ESC Full-Off Mode is active, the FCW
system will be automatically deactivated.
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 responsibility
to avoid a collision by controlling the ve-
hicle via braking and steering. Failure to
follow this warning could lead to serious
injury or death.
