254STARTING AND OPERATING
advantage to increasing ride height is the posi -
tive effect it has on approach/departure and
break over angles.
This system is controlled by the electronic
control sway bar switch located below the
instrument panel.

Sway Bar Disconnect Button

Push the SWAY BAR switch to activate the
system. Push the switch again to deactivate the
system. The “Sway Bar Indicator Light” (located
in the instrument cluster) will illuminate when
the bar is disconnected. The “Sway Bar Indi -
cator Light” will flash during activation transi -
tion, or when activation conditions are not met.
The stabilizer/sway bar should remain in
on-road mode during normal driving conditions. To disconnect the stabilizer/sway bar, shift to
either 4WD HIGH or 4WD LOW and push the
SWAY BAR button to obtain the Off-Road posi
-
tion. Refer to “Four Wheel Drive Operation” in
“Starting And Operating” for further informa -
tion. The “Sway Bar Indicator Light” will flash
until the stabilizer/sway bar has been fully
disconnected. NOTE:
The stabilizer/sway bar may be torque locked
due to left and right suspension height differ
-
ences. This condition is due to driving surface
differences or vehicle loading. In order for the
stabilizer/sway bar to disconnect/reconnect,
the right and left halves of the bar must be
aligned. This alignment may require that the
vehicle be driven onto level ground or rocked
from side to side.
To return to the On-Road mode, push the SWAY
BAR button again.WARNING!
Do not disconnect the stabilizer bar and drive
on hard surfaced roads or at speeds above
18 mph (29 km/h), you may lose control of
the vehicle, which could result in serious
injury or death. The front stabilizer bar
enhances vehicle stability and assists in
maintaining control of the vehicle. The system
monitors vehicle speed and will attempt to
reconnect the stabilizer bar at speeds over
18 mph (29 km/h). This is indicated by a
flashing off road light and solid on road light.
Once vehicle speed is reduced below 14 mph
(22 km/h), the system will attempt to return
to the Off-Road mode.
WARNING!
If the stabilizer/sway bar will not return to
On-Road mode, vehicle stability is reduced.
Do not attempt to drive the vehicle over
18 mph (29 km/h). Driving faster than
18 mph (29 km/h) may cause loss of control
of the vehicle, which could result in serious
injury or death. Contact your local service
center for assistance.

264STARTING AND OPERATING
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.
LIMITED-SLIP DIFFERENTIAL
The limited-slip differential provides additional
traction on snow, ice, mud, sand and gravel,
particularly when there is a difference between
the traction characteristics of the surface under
the right and left rear wheels. During normal
driving and cornering, the limited-slip unit
performs similarly to a conventional differential.
On slippery surfaces, however, the differential
delivers more of the driving effort to the rear
wheel having the better traction.
The limited-slip differential is especially helpful
during slippery driving conditions. With both
rear wheels on a slippery surface, a slight appli -
cation of the accelerator will supply maximum
traction. When starting with only one rear wheel
on an excessively slippery surface, slight
momentary application of the parking brake
may be necessary to gain maximum traction. Care should be taken to avoid sudden accelera-
tions when both rear wheels are on a slippery
surface. This could cause both rear wheels to
spin, and allow the vehicle to slide sideways on
the crowned surface of a road or in a turn.
WINCH USAGE — POWER WAGON ONLY (IF
EQUIPPED)
Things To Know Before Using Your Winch
General Winch Information
Your vehicle is equipped with an electric vehicle
recovery winch. This winch uses the electrical
power from the vehicle charging system to
power a motor that winds the winch rope onto
the winch drum via planetary gear reduction. By
nature, a winch is capable of generating very
high forces and should be used with care. Do
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.
WARNING!
On vehicles equipped with a limited-slip
differential never run the engine with one rear
wheel off the ground since the vehicle may
drive through the rear wheel remaining on the
ground. You could lose control of the vehicle.

STARTING AND OPERATING299
LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at speeds
above 37 mph (60 km/h) and below 112 mph
(180 km/h). It uses a forward looking camera to
detect lane markings and measure vehicle posi -
tion within the lane boundaries.
When both lane markings are detected and the
driver unintentionally drifts out of the lane while
no turn signal has been applied OR the driver
departs the lane on the opposite side of the
applied turn signal (if the left turn signal is applied and the vehicle departs to the right), the
LaneSense system provides a haptic warning in
the form of torque applied to the steering wheel
to prompt the driver to remain within the lane
boundaries. The LaneSense system will also
provide a visual warning through the instrument
cluster display to prompt the driver to remain
within the lane boundaries.
The driver may manually override the haptic
warning by applying torque into the steering
wheel at any time.
When only a single lane marking is detected
and the driver unintentionally drifts across that
lane marking (no turn signal applied), the Lane
-
Sense system provides a visual warning
through the instrument cluster display to
prompt the driver to remain within the lane.
When only a single lane marking is detected, a
haptic (torque) warning will not be provided.
NOTE:
When operating conditions have been met, the
LaneSense system will monitor if the driver’s
hands are on the steering wheel and provides
an audible and visual warning to the driver
when the driver’s hands are not detected on the
steering wheel. The system will cancel if the
driver does not return their hands to the wheel.
WARNING!
Drivers must be careful when backing up
even when using ParkSense. Always check
carefully behind your vehicle, look behind
you, and be sure to check for pedestrians,
animals, other vehicles, obstructions, and
blind spots before backing up. You are
responsible for safety and must continue to
pay attention to your surroundings. Failure
to do so can result in serious injury or
death.
Before using ParkSense, it is strongly
recommended that the ball mount and
hitch ball assembly is disconnected from
the vehicle when the vehicle is not used for
towing. Failure to do so can result in injury
or damage to vehicles or obstacles
because the hitch ball will be much closer
to the obstacle than the rear fascia when
the loudspeaker sounds the continuous
tone. Also, the sensors could detect the ball
mount and hitch ball assembly, depending
on its size and shape, giving a false indica -
tion that an obstacle is behind the vehicle.
CAUTION!
ParkSense is only a parking aid and it is
unable to recognize every obstacle,
including small obstacles. Parking curbs
might be temporarily detected or not
detected at all. Obstacles located above or
below the sensors will not be detected
when they are in close proximity.
The vehicle must be driven slowly when
using ParkSense in order to be able to stop
in time when an obstacle is detected. It is
recommended that the driver looks over
his/her shoulder when using ParkSense.

Lane Crossed (Flashing Yellow Lane Line) With Yellow
Telltale

NOTE:
The LaneSense system operates with similar
behavior for a right lane departure when only
the right lane marking has been detected.
Left Lane Departure — Both Lane Lines
Detected
When the LaneSense system is on and both
the lane markings have been detected, the
system is "armed" to provide visual warnings
in the instrument cluster display and a torque
warning in the steering wheel if an uninten -
tional lane departure occurs. The lane lines
turn from gray to white and the LaneSense
telltale is solid green.
Lanes Sensed (White Lines) With Green Telltale

When the LaneSense system senses a lane
drift situation, the left lane line turns solid
yellow. The LaneSense telltale changes
from solid green to solid yellow. At this time
torque is applied to the steering wheel in the
opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.

Lane Approached (Solid Yellow Lane Line) With Solid
Yellow Telltale

When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the left lane line flashes yellow
(on/off). The LaneSense telltale changes
from solid yellow to flashing yellow. At this
time torque is applied to the steering wheel in
the opposite direction of the lane boundary.
For example: If approaching the left side of
the lane the steering wheel will turn to the
right.5

PARKVIEW REAR BACK UP CAMERA
Your vehicle may be equipped with the
ParkView Rear Back Up Camera that allows you
to see an image of the rear surroundings of your
vehicle whenever the gear selector is put into
REVERSE or whenever it is initiated through the
"Backup Camera" button in the "Controls"
menu. Whenever the gear selector is put into
REVERSE, the image will be displayed in the
rearview mirror display (if equipped) or Ucon -
nect screen (if equipped). If the image is
displayed in the Uconnect screen, a caution
note to “check entire surroundings” will display across the top of the screen. After five seconds
this note will disappear.
Manual Activation Of The Rear View Camera:

1. Press the "Controls" button located on the
bottom of the Uconnect display.

2. Press the "Backup Camera" button to turn the Rear View Camera system on.
When the vehicle is shifted out of REVERSE

6. Finish tightening the lug nuts. Push down on the lug wrench while at the end of the handle
for increased leverage. Tighten the lug nuts in
a star pattern until each nut has been tight -
ened twice. For the correct lug nut torque refer
to “Wheel And Tire Torque Specifications” in
“Technical Specifications”. If in doubt about
the correct tightness, have them checked with
a torque wrench by an authorized dealer or
service station. 7. Install the wheel center cap and remove the
wheel blocks. Do not install chrome or
aluminum wheel center caps on the spare
wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. Stow the replaced tire, jack, and tools as
previously described.
NOTE:
The bottle jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary to
use the jack driver in order to lower the jack.
9. Adjust the tire pressure when possible.

IDENTIFICATION DATA
Vehicle Identification Number
The Vehicle Identification Number (VIN) is found
on the left front corner of the instrument panel,
visible through the windshield.
Vehicle Identification Number

NOTE:
It is illegal to remove or alter the VIN.
BRAKE SYSTEM
If power assist is lost for any reason (for
example, repeated brake applications with the
engine off), the brakes will still function. However, you will experience a substantial
increase in braking effort to stop the vehicle.
If either the front or rear hydraulic system loses
normal braking capability, the remaining
system will still function with some loss of
overall braking effectiveness. This will be
evident by increased pedal travel during appli
-
cation, greater pedal force required to slow or
stop, and activation of the “Brake Warning
Light” and/or the “ABS Warning Light” during
brake use.
Hydraulic Brake Assist — If Equipped
The brake system power assist is provided by a
hydro-boost unit which shares fluid with the
power steering system. You may experience
some clicking or hissing noises from the
hydro-boost system during hard braking condi -
tions.
NOTE:
Under cold temperatures, pedal effort will be
higher than normal until the power steering fluid
reaches operating temperature.
WHEEL AND TIRE TORQUE SPECIFICATIONS
Proper lug nut/bolt torque is very important to
ensure that the wheel is properly mounted to
the vehicle. Any time a wheel has been removed
and reinstalled on the vehicle, the lug nuts/
bolts should be torqued using a properly cali -
brated torque wrench using a high quality six
sided (hex) deep wall socket.
