STARTING AND OPERATING307
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
LaneSense 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.
TURNING LANESENSE ON OR OFF
The LaneSense button is located on
the switch panel below the Uconnect
display.
NOTE:
If your vehicle is equipped with a 12–inch Ucon -
nect Display screen, the LaneSense button is
located above the display.
To turn the LaneSense system on, push the
LaneSense button (LED turns off). A
“LaneSense On” message is shown in the
instrument cluster display.
Lane Sense On Message
To turn the LaneSense system off, push the
LaneSense button again (LED turns on).
NOTE:
The LaneSense system will retain the last system
state (on or off) from the last ignition cycle when
the ignition is placed in the ON/RUN position.
LANESENSE WARNING MESSAGE
The LaneSense system will indicate the current
lane drift condition through the instrument
cluster display.
When the LaneSense system is on, the lane
lines are gray when both of the lane boundaries
have not been detected and the LaneSense
telltale is solid white.

308STARTING AND OPERATING
Left Lane Departure — Only Left Lane Detected
When the LaneSense system is on, the Lane -
Sense Telltale is solid white when only the
left lane marking has been detected and the
system is ready to provide visual warnings in
the instrument cluster display if an uninten -
tional lane departure occurs on the left side.
When the LaneSense system senses the lane
has been approached and is in a lane depar -
ture situation, the visual warning in the
instrument cluster display will show the left
lane line flashing yellow (on/off). The Lane -
Sense telltale changes from solid white to
flashing yellow.
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.

STARTING AND OPERATING309
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.
Lane Crossed (Flashing Yellow Lane Line) With Flashing Yellow Telltale
NOTE:
The LaneSense system operates with similar
behavior for a right lane departure.
CHANGING LANESENSE STATUS
The LaneSense system has settings to adjust
the intensity of the torque warning and the
warning zone sensitivity (Early/Medium/Late)
that you can configure through the Uconnect
system screen. Refer to “Uconnect Settings” in
“Multimedia” for further information.
NOTE:
When enabled the system operates above
37 mph (60 km/h) and below 112 mph
(180 km/h).
Use of the turn signal suppresses the warn -
ings.
The system will not apply torque to the
steering wheel whenever a safety system
engages (Anti-Lock Brakes, Traction Control
System, Electronic Stability Control, Forward
Collision Warning, etc.).
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
Uconnect 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" icon to turn the Rear View Camera system on.
When the vehicle is shifted out of REVERSE (with
Camera delay turned off), the rear Camera mode
is exited and the previous screen appears again.

STARTING AND OPERATING345
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.

372IN CASE OF EMERGENCY
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 tightened twice. For the correct lug nut
torque refer to “Wheel And Tire Torque
Specifications” in “Technical Specifi -
cations”. 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.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated lug nuts.
TO STOW THE FLAT OR SPARE
NOTE:
Have the flat tire repaired or replaced immedi -
ately.
1. Turn the wheel so that the valve stem is facing the ground and toward the rear of
the vehicle for convenience in checking the
spare tire inflation. Slide the wheel retainer
through the center of the wheel.
Reinstalling The Retainer
2. Lift the spare tire with one hand to give clearance to tilt the retainer at the end of
the cable and position it properly across the
wheel opening.
WARNING!
A loose tire or jack thrown forward in a
collision or hard stop, could endanger the
occupants of the vehicle. Always stow the jack
parts and the spare tire in the places
provided.

TECHNICAL SPECIFICATIONS
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
application, 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
E
QUIPPED
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
conditions.
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
calibrated torque wrench using a high quality six
sided (hex) deep wall socket.
TORQUE SPECIFICATIONS
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.

NOTE:
Dual wheels are flat mounted, center piloted.
The lug nuts are a two-piece assembly. When
the tires are being rotated or replaced, clean
these lug nuts and add two drops of oil at the
interface between the lug nut/bolt and the
washer. Do not oil wheel studs.
Two-Piece Lug Nut
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
Wheel Mounting Surface
Tighten the lug nuts/bolts in a star pattern until
each nut/bolt has been tightened twice. Ensure
that the socket is fully engaged on the lug nut/
bolt (do not insert it halfway).
After 25 miles (40 km), check the lug nut/bolt torque to be sure that all the lug nuts/bolts are
properly seated against the wheel.
Four And Five Lug Nuts/Bolts Torque Pattern
WARNING!
To avoid the risk of forcing the vehicle off the
jack, do not tighten the lug nuts/bolts fully
until the vehicle has been lowered. Failure to
follow this warning may result in personal
injury.
