256STARTING AND OPERATING
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.
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
Uconnect Display screen, the LaneSense button
is located above the display. To turn the LaneSense system on, push the
LaneSense button (LED turns off). A “Lane
-
Sense 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 changed to the
ON/RUN position.

STARTING AND OPERATING257
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 tell -
tale is solid white.

System ON (Gray Lines) With White Telltale 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.

258STARTING AND OPERATING
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.

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 (Low/Medium/High) 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 a 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.

IN CASE OF EMERGENCY317
5. Remove the lug nuts and pull the wheel off.
Install the spare wheel and lug nuts with the
cone shaped end of the nuts toward the
wheel on Single Rear-Wheel (SRW) models.
On Dual Rear-Wheel models (DRW) the lug
nuts are a two-piece assembly with a flat
face. Lightly tighten the nuts. To avoid risk
of forcing the vehicle off the jack, do not
fully tighten the nuts until the vehicle has
been lowered.
6. Using the lug wrench, finish tightening the nuts using a crisscross pattern. For the
proper lug nut torque specifications 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 at a service station. 7. Install wheel center cap (if equipped) and
remove 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. If the 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. Stow the replaced tire, jack, and tools
as previously described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut torque with a torque wrench to ensure that
all lug nuts are properly seated against the
wheel.
Dual Rear Wheels
Slots in the wheels will assist in properly
orienting the inner and outer wheels. Align
these slots when assembling the wheels for
best access to the tire valve on the inner wheel.
The tires of both dual wheels must be
completely off the ground when tightening to
insure wheel centering and maximum wheel
clamping.
Dual wheel models require a special heavy-duty
lug nut tightening adapter (included with the
vehicle) to correctly tighten the lug nuts. Also,
when it is necessary to remove and install dual
rear wheels, use a proper vehicle lifting device.
NOTE:
When installing a spare tire (if equipped) as part
of a dual rear wheel end combination, the tire
diameter of the two individual tires must be
compared. If there is a significant difference,
the larger tire should be installed in a front loca-
tion. The correct direction of rotation for dual
tire installations must also be observed.WARNING!
Raising the vehicle higher than necessary can
make the vehicle less stable. It could slip off
the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
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.

318IN CASE OF EMERGENCY
It is recommended that wheel stud nuts be kept
torqued to specifications at all times. Torque
wheel stud nuts to specifications at each lubri -
cation interval.
Refer to “Wheel And Tire Torque Specifications”
in “Technical Specifications” for further infor -
mation.
Wheel Nuts
All wheel nuts should be tightened occasionally
to eliminate the possibility of wheel studs being
sheared or the bolt holes in the wheels
becoming elongated. This is especially
important during the first few hundred miles/
kilometers of operation to allow the wheel nuts
to become properly set. All wheel nuts should
first be firmly seated against the wheel. The
wheel nuts should then be tightened to recom -
mended torque. Tighten the wheel nuts to final
torque in increments. Progress around the bolt
circle, tightening the wheel nut opposite to the
wheel nut just previously tightened until final
torque is achieved. Refer to “Wheel And Tire Torque Specifications”
in “Technical Specifications” for further infor
-
mation.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builder’s Guide for infor -
mation on stowing your spare tire (if equipped).
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising
the vehicle off the ground. For 3500 Single Rear-Wheel (SRW) models, use
the flat end of the lug wrench to hook and pull
off the hub cap. Find the opening in the hub cap,
insert the lug wrench, and pull off the cap. If you
need to pry against the wheel, protect the wheel
surface.

Lug Wrench Insertion Location — Hub Cap

CAUTION!
Use extreme caution when removing the front
and rear wheel covers. Damage can occur to
the center cap and/or the wheel if
screwdriver type tools are used. A pulling
motion, not a pry off motion, is recommended
to remove the caps.

368SERVICING AND MAINTENANCE
Automatic Transmission
Selection Of Lubricant
It is important to use the proper transmission
fluid to ensure optimum transmission perfor-
mance and life. Use only the manufacturer’s
specified transmission fluid. Refer to “Fluids
And Lubricants” in “Technical Specifications”. It
is important to maintain the transmission fluid
at the correct level using the recommended
fluid. No chemical flushes should be used in any
transmission; only the approved lubricant
should be used.
Special Additives
The manufacturer strongly recommends
against using any special additives in the trans -
mission. Automatic Transmission Fluid (ATF) is
an engineered product and its performance
may be impaired by supplemental additives.
Therefore, do not add any fluid additives to the
transmission. The only exception to this policy is
the use of special dyes for diagnosing fluid
leaks in six-speed transmissions. Avoid using
transmission sealers as they may adversely
affect seals.
Fluid Level Check — Eight-Speed
Transmission
The fluid level is preset at the factory and does
not require adjustment under normal operating
conditions. Routine fluid level checks are not
required, therefore the transmission has no dipstick. An authorized dealer can check your
transmission fluid level using special service
tools.
If you notice fluid leakage or transmission
malfunction, visit an authorized dealer immedi
-
ately to have the transmission fluid level
checked. Operating the vehicle with an
improper fluid level can cause severe transmis -
sion damage.
Fluid Level Check — Six-Speed Transmission
It is best to check the fluid level when the trans -
mission is at normal operating temperature
(158-176°F / 70-80°C). This normally occurs
after at least 15 miles (25 km) of driving. At
normal operating temperature the fluid cannot
be held comfortably between the fingertips. You
can read the transmission sump temperature in
the instrument cluster screen (refer to “Instru -
ment Cluster Display” in “Getting To Know Your
Instrument Panel” for further information).
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may
cause deterioration in transmission shift
quality and/or torque converter shudder, and
(for six-speed transmissions) will require
more frequent fluid and filter changes. Refer
to “Fluids And Lubricants” in “Technical
Specifications” for fluid specifications.
CAUTION!
Do not use chemical flushes in your
transmission as the chemicals can damage
your transmission components. Such damage
is not covered by the New Vehicle Limited
Warranty.
CAUTION!
If a transmission fluid leak occurs, visit an
authorized dealer immediately. Severe
transmission damage may occur. An
authorized dealer has the proper tools to
adjust the fluid level accurately.

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. This number
also appears on the vehicle frame etched on
right hand center rail, as well as the Automobile
Information Disclosure Label affixed to a
window on your vehicle, the vehicle registration
and title.
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.

Torque Specifications
**Use only authorized dealer recommended
lug nuts/bolts and clean or remove any dirt or
oil before tightening.
Inspect the wheel mounting surface prior to
mounting the tire and remove any corrosion or
loose particles.
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 hex and the washer.
Ensure that the socket is fully engaged on the
lug nut/bolt (do not insert it half way).

Oil Interface Location

Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.

Wheel Mounting Surface
Retighten the wheel nuts in the same sequence
to the torques listed in the table. Go through the
sequence a second time to verify that specific
torque has been achieved. Retighten to specifi
-
cations after 25 miles (40 km) and check the
lug nut/bolt torque to be sure that all the lug
nuts/bolts are properly seated against the
wheel.

6.4L Engine
Do not use E-85 flex fuel or ethanol blends
greater than 15% in this engine.
This engine is designed to meet all
emissions regulations and provide
satisfactory fuel economy and perfor -
mance when using high quality
unleaded gasoline having a posted octane
number range of 87 to 89 as specified by the
(R+M)/2 method. The use of 89 octane “Plus”
gasoline is recommended for optimum perfor -
mance and fuel economy.
While operating on gasoline with an octane
number of 87, hearing a light knocking sound
from the engine is not a cause for concern.
However, if the engine is heard making a heavy
knocking sound, see dealer immediately. Use of
gasoline with an octane number lower than 87
can cause engine failure and may void or not be
covered by the New Vehicle Limited Warranty. Poor quality gasoline can cause problems such
as hard starting, stalling, and hesitations. If you
experience these symptoms, try another brand
of gasoline before considering service for the
vehicle.
Reformulated Gasoline
Many areas of the country require the use of
cleaner burning gasoline referred to as “Refor
-
mulated Gasoline”. Reformulated gasoline
contains oxygenates and are specifically
blended to reduce vehicle emissions and
improve air quality.
The use of reformulated gasoline is recom -
mended. Properly blended reformulated gaso -
line will provide improved performance and
durability of engine and fuel system compo -
nents.
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.
