Electronic Stability Control (ESC)
This system enhances directional control and
stability of the vehicle under various driving
conditions. Electronic Stability Control (ESC)
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the oversteer
or understeer condition. Engine power may also
be reduced to help the vehicle maintain the
desired path. 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 posi
-
tion.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel posi -
tion.
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 Traction
Control System (TCS) 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.
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.
WARNING!
Electronic Stability Control (ESC) cannot
prevent the natural laws of physics from
acting on the vehicle, nor can it increase
the traction afforded by prevailing 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 resulting from loss of
vehicle control due to inappropriate driver
input for the conditions. Only a safe, atten -
tive, and skillful driver can prevent acci -
dents. The capabilities of an ESC equipped
vehicle must never be exploited in a reck -
less or dangerous manner which could
jeopardize the user’s safety or the safety of
others.

ESC Operating Modes
NOTE:
Depending upon model and mode of operation,
the ESC system may have multiple operating
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 should be used
for most driving conditions. Alternate ESC
modes should only be used for specific reasons
as noted in the following paragraphs.
Partial Off
The “Partial Off” mode is intended for times
when a more spirited driving experience is
desired. This mode may modify TCS and ESC
thresholds for activation, which allows for more
wheel spin than normally allowed. This mode
may be useful if the vehicle becomes stuck.
To enter the “Partial Off” mode, momentarily
push the “ESC OFF” switch and the “ESC OFF
Indicator Light” will illuminate. To turn the ESC
on again, momentarily push the “ESC OFF”
switch and the “ESC OFF Indicator Light” will
turn off. NOTE:
For vehicles with multiple partial ESC modes a
momentary button push will toggle the ESC
mode. Multiple momentary button pushes may
be required to return to “ESC On” mode.Vehicle modifications, or failure to properly
maintain your vehicle, may change the
handling characteristics of your vehicle,
and may negatively affect the performance
of the ESC system. Changes to the steering
system, suspension, braking system, tire
type and size or wheel size may adversely
affect ESC performance. Improperly
inflated and unevenly worn tires may also
degrade ESC performance. Any 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.
WARNING!
(Continued)
WARNING!
When in “Partial Off” mode, the TCS func -
tionality 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.

Resetting Active Head Restraints (AHR)
Active Head Restraint (AHR) Deployed
If the Active Head Restraints are triggered
during a collision, the front half of the head
restraint will be extended forward and
separated from the rear half of the head
restraint (See Image). Do not drive your vehicle
after the AHRs have deployed. The head
restraint must be reset into the original position
to best protect the occupant for all types of
collisions. An authorized FCA US LLC dealer
must reset the AHRs on the driver’s and front
passenger’s seat before driving. Personally
attempting to reset the AHRs may result in
damage to the AHRs that could impair their
function.
SUPPLEMENTAL RESTRAINT SYSTEMS
(SRS)
Some of the safety features described in this
section may be standard equipment on some
models, or may be optional equipment on
others. If you are not sure, ask an authorized
dealer.
The air bag system must be ready to protect you
in a collision. The Occupant Restraint Controller
(ORC) monitors the internal circuits and
interconnecting wiring associated with the
electrical Air Bag System Components. Your
vehicle may be equipped with the following Air

STARTING AND OPERATING199
SPORT MODE — IF EQUIPPED
Your vehicle is equipped with a Sport Mode
feature. This mode is a configuration set up for
typical enthusiast driving. The engine,
transmission, and steering systems are all set
to their SPORT settings. Sport Mode will provide
improved throttle response and modified
transmission shift points for an enhanced
driving experience, as well as greater amount of
steering feel. This mode may be activated and
deactivated by pushing the Sport button on the
instrument panel switch bank.
ALL-WHEEL DRIVE OPERATION
SINGLE-SPEED OPERATING
I
NSTRUCTIONS/PRECAUTIONS— IF
E
QUIPPED
This system contains a single-speed (HI range
only) transfer case, which provides convenient
full-time All-Wheel Drive (AWD). No driver
interaction is required. The Brake Traction
Control (BTC) System, which combines standard
ABS and Traction Control, provides resistance
to any wheel that is slipping to allow additional
torque transfer to wheels with traction. NOTE:
This system is not appropriate for conditions
where LOW range is recommended. Refer to
“Driving Tips” in this chapter for further informa-
tion.
ELECTRONICALLY SHIFTED TRANSFER
C
ASE (THREE-POSITION SWITCH) — IF
E
QUIPPED
This is an electronically shifted transfer case
and it is operated by the AWD Control Switch,
which is located on the center console.
AWD Control Switch (Three-Position)
This electronically shifted transfer case
provides three mode positions:
All-wheel drive automatic range (AWD AUTO)
All-wheel drive low range (LOW RANGE)
Neutral (NEUTRAL)
This electronically shifted transfer case is
designed to be driven in the AWD AUTO position
for normal street and highway conditions on dry
hard surfaced roads.
For variable driving conditions, the AWD AUTO
mode can be used. In this mode, the front axle
is engaged, but the vehicle's power is sent to
the rear wheels. All-wheel drive will be
automatically engaged when the vehicle senses
a loss of traction.
When additional traction is required, the
transfer case LOW RANGE position can be used
to lock the front and rear driveshafts together
forcing the front and rear wheels to rotate at the
same speed. This is accomplished by rotating
the AWD Control Switch to the desired position.
Refer to “Shifting Procedure” for specific
shifting instructions.

20_WD_OM_EN_USC_t.book Page 199
202STARTING AND OPERATING
Preferred Procedure
1. With the engine running, slow the vehicle
to 2 to 3 mph (3 to 5 km/h).
2. Shift the transmission into NEUTRAL.
3. While still rolling, rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear.
Alternate Procedure
1. Bring the vehicle to complete stop.
2. With the ignition in ON/RUN position and engine running, shift the transmission to
NEUTRAL.
3. Rotate the AWD control switch to the desired position.
4. After the desired position indicator light is on (not flashing), shift the transmission
back into gear. NOTE:
If steps 1 or 2 of either the Preferred or Alter
-
nate Procedure are not satisfied prior to
attempting the shift or if they no longer are
being met while the shift attempt is in
process, the desired position indicator light
will flash continuously while the original posi -
tion indicator light is on, until all require -
ments have been met.
The ignition switch must be in the ON/RUN
position for a shift to take place and for the
position indicator lights to be operable. If the
ignition switch is not in the ON/RUN position,
then the shift will not take place and no posi -
tion indicator lights will be on or flashing.
NEUTRAL Shift Procedure
For information regarding the transfer case
NEUTRAL (N) shift procedure, refer to “Shifting
Into NEUTRAL (N)” in “Recreational Towing” in
this chapter.
FUEL SAVER TECHNOLOGY 5.7L/6.4L ONLY
— IF EQUIPPED
This feature offers improved fuel economy by
shutting off four of the engine's eight cylinders
during light load and cruise conditions. The
system is automatic with no driver inputs or
additional driving skills required.
NOTE:
This system may take some time to return to full
functionality after a battery disconnect.
POWER STEERING
The electric power steering system will give you
good vehicle response and increased ease of
maneuverability in tight spaces. The system will
vary its assist to provide light efforts while
parking and good feel while driving. If the
electric steering system experiences a fault that
prevents it from providing assist, you will still
have the ability to steer the vehicle manually.
20_WD_OM_EN_USC_t.book Page 202
STARTING AND OPERATING203
Alternate electric power steering efforts can be
selected through the Uconnect System. Refer to
”Customer Programmable Features” within
“Uconnect Settings” in “Multimedia” for further
information.
If the Electric Power Steering warning
icon is displayed and the “SERVICE
POWER STEERING” or the “POWER
STEERING ASSIST OFF – SERVICE
SYSTEM” message is displayed within the
instrument cluster display, this indicates the
vehicle needs to be taken to the dealer for
service. Refer to “Warning Lights And
Messages” in “Getting To Know Your
Instrument Panel” for further information. NOTE:
Even if the power steering assistance is no
longer operational, it is still possible to steer
the vehicle. Under these conditions there will
be a substantial increase in steering effort,
especially at low speeds and during parking
maneuvers.
If the condition persists, see an authorized
dealer for service.
If the Steering icon is displayed and the
“POWER STEERING SYSTEM OVER TEMP”
message is displayed on the instrument cluster
screen, they indicate that extreme steering
maneuvers may have occurred which caused
an over temperature condition in the power
steering system. Once driving conditions are
safe, pull over and let the vehicle idle for a few
moments until the icon and message turn off.
STOP/START SYSTEM — IF EQUIPPED
The Stop/Start function is developed to reduce
fuel consumption. The system will stop the
engine automatically during a vehicle stop if the
required conditions are met. Releasing the
brake pedal or pressing the accelerator pedal
will automatically re-start the engine. This vehicle has been upgraded with a heavy
duty starter, enhanced battery, and other
upgraded engine parts, to handle the additional
engine starts.
AUTOMATIC MODE
The Stop/Start feature is enabled
after every normal customer engine
start. At that time, the system will go
into STOP/START READY and if all
other conditions are met, can go into a STOP/
START AUTOSTOP ACTIVE “Autostop” mode.
To Activate The Autostop Mode, The Following
Must Occur:
The system must be in STOP/START READY
state. A STOP/START READY message will be
displayed in the instrument cluster display
within the Stop/Start section. Refer to
“Instrument Cluster” in “Getting To Know
Your Instrument Panel” for further informa -
tion.
The vehicle must be completely stopped.
The gear selector must be in a forward gear
and the brake pedal depressed.
WARNING!
Continued operation with reduced assist
could pose a safety risk to yourself and
others. Service should be obtained as soon
as possible.

260STARTING AND OPERATING
After Driving Off-Road
Off-road operation puts more stress on your
vehicle than does most on-road driving. After
going off-road, it is always a good idea to check
for damage. That way you can get any problems
taken care of right away and have your vehicle
ready when you need it.
Completely inspect the underbody of your
vehicle. Check tires, body structure, steering,
suspension, and exhaust system for damage.
Inspect the radiator for mud and debris and
clean as required.
Check threaded fasteners for looseness,
particularly on the chassis, drivetrain compo -
nents, steering, and suspension. Retighten
them, if required, and torque to the values
specified in the Service Manual.
Check for accumulations of plants or brush.
These things could be a fire hazard. They
might hide damage to fuel lines, brake hoses,
axle pinion seals, and propeller shafts.
After extended operation in mud, sand,
water, or similar dirty conditions, have the
radiator, fan, brake rotors, wheels, brake
linings, and axle yokes inspected and
cleaned as soon as possible.
If you experience unusual vibration after
driving in mud, slush or similar conditions,
check the wheels for impacted material.
Impacted material can cause a wheel imbal-
ance and freeing the wheels of it will correct
the situation.
WARNING!
Abrasive material in any part of the brakes
may cause excessive wear or unpredictable
braking. You might not have full braking
power when you need it to prevent a collision.
If you have been operating your vehicle in
dirty conditions, get your brakes checked and
cleaned as necessary.
