Closing
There are several different ways to close the
liftgate:
• Manually by grasping the liftgate closing
handle and initiating lowering of the lift-
gate. Release the handle when the liftgate
takes over the closing effort.
• Key Fob
• Hands-Free
• Liftgate Instrument Panel Button
• Power Liftgate Button On The Pillar In The
Cargo Area
To Lock The Liftgate
With a valid Passive Entry key fob within 5 ft
(1.5 m) of the liftgate, pushing the Keyless
Enter-N-Go — Passive Entry lock/push but-
ton located to the left of the back-up camera
will lock the vehicle only.The power liftgate may be closed by pushing
the button, located in the upper left trim in
the liftgate opening. Pushing the button will
only close the liftgate. This button cannot be
used to open the liftgate.
Hands-Free Liftgate — If Equipped
To open or close the liftgate using hands-free
activation, use a straight in and out kicking
motion under the vehicle activation zone in
the general location below the rear license
plate. Do not move your foot sideways or in a
sweeping motion or the sensors may not de-
tect the motion.

GETTING TO KNOW YOUR VEHICLE
56

NOTE:
Activation zone is the same for vehicles
equipped with and without trailer tow package.
When a valid kicking motion is completed,
the liftgate will chime, the hazard lights will
flash and the liftgate will open after approxi-
mately one second, or close after approxi-
mately three seconds. This assumes all op-
tions are enabled in the radio.
NOTE:
• Opening or closing the Hands-Free Liftgate
requires a valid Passive Entry key fob within
5 ft (1.5 m) of the door handle. If a valid
Passive Entry key fob is not within 5 ft
(1.5 m), the liftgate will not respond to any
kicks.
• The Hands-Free Liftgate feature may be
turned on or off in Uconnect Settings. Refer
to “Uconnect Settings” in “Multimedia” in
the Owner’s Manual for further information.
The Hands-Free Liftgate feature should be
turned off during Jacking, Tire Changing,
Manual Car Wash, and Vehicle Service.NOTE:
The Hands-free liftgate feature can be acti-
vated by any metallic object making a similar
in-and-out motion under the rear bumper,
such as cleaning using a metal broom.
NOTE:
• The Hands-Free Liftgate will only operate
when the transmission is in PARK.
• If anything obstructs the Hands-Free lift-
gate while it is opening or closing, the
liftgate will automatically reverse to the
closed/open position, provided it meets
sufficient resistance.
• There are pinch sensors attached to the
side of the liftgate opening. Light pressure
anywhere along these strips will cause the
liftgate to return to the open position.
• If the power liftgate encounters multiple
obstructions within the same cycle, the
system will automatically stop. If this oc-
curs, the liftgate must be operated manu-
ally.• The power liftgate will release, but not
power open, in temperatures below −12° F
(−24° C). Be sure to remove any buildup of
snow or ice from the liftgate before opening
the liftgate.
• If the liftgate is left open for an extended
period of time, the liftgate may need to be
closed manually to reset power liftgate
functionality.
WARNING!
• Driving with the liftgate open can allow
poisonous exhaust gases into your ve-
hicle. You and your passengers could be
injured by these fumes. Keep the liftgate
closed when you are operating the ve-
hicle.
• If you are required to drive with the
liftgate open, make sure that all win-
dows are closed, and the climate control
blower switch is set at high speed. Do
not use the recirculation mode.

CAUTION!
Do not continue driving with one or more
flat tires as handling may be compro-
mised. Stop the vehicle, avoiding sharp
braking and steering. If a tire puncture
occurs, repair immediately using the dedi-
cated tire repair kit and contact an autho-
rized dealer as soon as possible.
Each tire, including the spare (if provided),
should be checked monthly when cold and
inflated to the inflation pressure recom-
mended by the vehicle manufacturer on the
vehicle placard or tire inflation pressure la-
bel. (If your vehicle has tires of a different
size than the size indicated on the vehicle
placard or tire inflation pressure label, you
should determine the proper tire inflation
pressure for those tires.)
As an added safety feature, your vehicle has
been equipped with a Tire Pressure Monitor-
ing System (TPMS) that illuminates a low tire
pressure telltale when one or more of your
tires is significantly under-inflated. Accord-
ingly, when the low tire pressure telltale illu-
minates, you should stop and check your tiresas soon as possible, and inflate them to the
proper pressure. Driving on a significantly
under-inflated tire causes the tire to overheat
and can lead to tire failure. Under-inflation
also reduces fuel efficiency and tire tread
life, and may affect the vehicle’s handling
and stopping ability.
Please note that the TPMS is not a substitute
for proper tire maintenance, and it is the
driver’s responsibility to maintain correct tire
pressure, even if under-inflation has not
reached the level to trigger illumination of the
TPMS low tire pressure telltale.
Your vehicle has also been equipped with a
TPMS malfunction indicator to indicate when
the system is not operating properly. The
TPMS malfunction indicator is combined
with the low tire pressure telltale. When the
system detects a malfunction, the telltale will
flash for approximately one minute and then
remain continuously illuminated. This se-
quence will continue upon subsequent ve-
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
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
71

CAUTION!
your authorized dealer to have your sensor
function checked.
Yellow Indicator Lights
— Active Speed Limiter Fault Indica-
tor Light — If Equipped
This warning light will illuminate to signal
when there is a fault detected with the Active
Speed Limiter.
— Forward Collision Warning Off Indi-
cator Light — If Equipped
This light indicates that Forward Collision
Warning is off.
— 4WD Low Indicator Light — If
Equipped
This light alerts the driver that the vehicle is
in the four-wheel drive LOW mode. The front
and rear driveshafts are mechanically locked
together forcing the front and rear wheels to
rotate at the same speed. Low range provides
a greater gear reduction ratio to provide in-
creased torque at the wheels.Refer to “Four-Wheel Drive Operation — If
Equipped” in “Starting And Operating” for
further information on four-wheel drive op-
eration and proper use.
— Rear Axle Lock Indicator Light
This light indicates when the rear axle lock
has been activated.
— Rear Fog Indicator — If Equipped
This indicator light will illuminate when the
rear fog lights are on.
— Glow Plug Light — If Equipped
This vehicle will inhibit engine cranking
when the ambient temperature is less than
–22° F (–30° C) and the oil temperature
sensor reading indicates an engine block
heater has not been used. The Glow Plug
light will flash during in cold weather for up
to ten seconds.
If equipped with a block heater harness the
message "Plug In Engine Heater", will be
displayed in the instrument cluster when theambient temperature is below 5°F (-15° C) at
the time the engine is shut off as a reminder
to avoid possible crank delays at the next cold
start.
— Low Diesel Exhaust Emissions Addi-
tive (UREA) Indicator Light — If Equipped
The Low Diesel Exhaust Emissions Additive
(UREA) indicator light illuminates when the
UREA level is low.
Fill the UREA tank as soon as possible with at
least 1.3 gallons (5 liters) of UREA.
If filling the tank is done with a remaining
range of UREA in the tank equal to zero, you
may need to wait 2 minutes before starting
the vehicle.
Refer to “Starting And Operating” for further
information.
— Water In Fuel Indicator Light — If
Equipped
The “Water In Fuel Indicator Light” will illu-
minate when there is water detected in the
fuel filter. If this light remains on, DO NOT

ESC uses sensors in the vehicle to determine
the vehicle path intended by the driver and
compares it to the actual path of the vehicle.
When the actual path does not match the
intended path, ESC applies the brake of the
appropriate wheel to assist in counteracting
the oversteer or understeer condition.
• Oversteer — when the vehicle is turning
more than appropriate for the steering
wheel position.
• Understeer — when the vehicle is turning
less than appropriate for the steering wheel
position.
The “ESC Activation/Malfunction Indicator
Light” located in the instrument cluster will
start to flash as soon as the ESC system
becomes active. The “ESC Activation/
Malfunction Indicator Light” also flashes
when the TCS is active. If the “ESC
Activation/Malfunction Indicator Light” be-
gins 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.WARNING!
• Electronic Stability Control (ESC) can-
not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize the user’s safety or the safety of
others.
• Vehicle modifications, or failure to prop-
erly maintain your vehicle, may change
the handling characteristics of your ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating modes.
ESC On
This is the normal operating mode for the
ESC. Whenever the vehicle is started, the
ESC system will be in this mode. This mode

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 (if equipped). 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 wheel lift or
rollover may occur. ERM cannot prevent
all wheel lift or roll overs, 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.
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize
an excessively swaying trailer and will take
the appropriate actions to attempt to stop the
sway. TSC will become active automatically
once an excessively swaying trailer is recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
When TSC is functioning, the “ESC
Activation/Malfunction Indicator Light” will
flash, the engine power may be reduced and
you may feel the brakes being applied to
individual wheels to attempt to stop the
trailer from swaying. TSC is disabled when
the ESC system is in the “Partial Off” or “Full
Off” modes.WARNING!
If TSC activates while driving, slow the
vehicle down, stop at the nearest safe
location, and adjust the trailer load to
eliminate trailer sway.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.

• 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.
• The cluster icon and switch lamp will illu-
minate and remain on solid when SSC is
enabled or activated. This is the normal
operating condition for SSC.• The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the SSC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash
for several seconds then extinguish when
SSC disables due to excess speed.
• The cluster icon and switch lamp will flash
then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
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-based sensors, located inside
the rear bumper fascia, to detect highway
licensable vehicles (automobiles, trucks, mo-
torcycles, 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 out-
side rear view mirrors to let the driver know
