STARTING AND OPERATING201
For additional information on the appropriate
use of each transfer case mode position, see
the information below:
AWD Auto
All-Wheel Drive Auto Range – This range sends
power to the rear wheels. The all-wheel drive
system will be automatically engaged when the
vehicle senses a loss of traction. Additional
traction for varying road conditions.
LOW Range
All-Wheel Drive Low Range – This range
provides low speed all-wheel drive. Locks the
front and rear driveshafts together forcing the
front and rear wheels to rotate at the same
speed. Additional traction and maximum pulling
power for loose, slippery road surfaces only. Do
not exceed 25 mph (40 km/h).
NEUTRAL (N)
This range disengages both the front and rear
driveshafts from the powertrain. To be used for
flat towing behind another vehicle. Refer to
“Recreational Towing” in this chapter for further
information.
SHIFTING PROCEDURE
NOTE:
If any of the requirements to select a new
transfer case position have not been met, the
transfer case will not shift. The position indi -
cator light for the previous position will
remain on and the newly selected position
indicator light will continue to flash until all
the requirements for the selected position
have been met. To retry a shift: return the control switch back
to the original position, make certain all shift
requirements have been met, wait five
seconds and try the shift again.
If all the requirements to select a new
transfer case position have been met, the
current position indicator light will turn off,
the selected position indicator light will flash
until the transfer case completes the shift.
When the shift is complete, the position indi
-
cator light for the selected position will stop
flashing and remain on.
AWD Auto To Low Range
NOTE:
When shifting into or out of LOW RANGE some
gear noise may be heard. This noise is normal
and is not detrimental to the vehicle or occu -
pants.
Shifting can be performed with the vehicle
rolling 2 to 3 mph (3 to 5 km/h) or completely
stopped. Use either of the following procedures:
WARNING!
You or others could be injured or killed if you
leave the vehicle unattended with the transfer
case in the NEUTRAL position without first
fully engaging the parking brake. The transfer
case NEUTRAL position disengages both the
front and rear drive shafts from the
powertrain and will allow the vehicle to roll,
even if the transmission is in PARK. The
parking brake should always be applied when
the driver is not in the vehicle.

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.

204STARTING AND OPERATING
The engine will shut down, the tachometer will
move to the zero position and the Stop/Start
telltale will illuminate indicating you are in
Autostop. Customer settings will be maintained
upon return to an engine running condition.
Refer to the “Stop/Start System” in the
“Starting And Operating” section for further
information.
POSSIBLE REASONS THE ENGINE DOES
N
OT AUTOSTOP
Prior to engine shut down, the system will check
many safety and comfort conditions to see if
they are fulfilled. Detailed information about the
operation of the Stop/Start system may be
viewed in the instrument cluster display Stop/
Start Screen. In the following situations, the
engine will not stop:

(Continued)
ADAPTIVE CRUISE CONTROL (ACC)
O
PERATION
The Speed Control buttons (located on the right
side of the steering wheel) operate the Adaptive
Cruise Control (ACC) system.
Adaptive Cruise Control Buttons

NOTE:
Any chassis / suspension or tire size modifica -
tions to the vehicle will affect the performance
of the ACC and Forward Collision Warning
system.
The ACC system:
Does not react to pedestrians,
oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather
conditions into account, and may be
limited upon adverse sight distance
conditions.
Does not always fully recognize
complex driving conditions, which can
result in wrong or missing distance
warnings.
Will bring the vehicle to a complete stop
while following a target vehicle and hold
the vehicle for two seconds in the stop
position. If the target vehicle does not
start moving within two seconds the
ACC system will display a message that
the system will release the brakes and
that the brakes must be applied manu -
ally. An audible chime will sound when
the brakes are released.
WARNING! (Continued)
You should switch off the ACC system:
When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway construc -
tion zones).
When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
When towing a trailer up or down steep
slopes.
When circumstances do not allow safe
driving at a constant speed.

20_WD_OM_EN_USC_t.book Page 209

STARTING AND OPERATING213
The ACC system applies the brake down to a
full stop when following a target vehicle. If an
ACC host vehicle follows a target vehicle to a
standstill, the host vehicle will release the
vehicle brakes two seconds after coming to a
full stop.
The ACC system maintains set speed when
driving uphill and downhill. However, a slight
speed change on moderate hills is normal. In
addition, downshifting may occur while
climbing uphill or descending downhill. This
is normal operation and necessary to main -
tain set speed. When driving uphill and down -
hill, the ACC system will cancel if the braking
temperature exceeds normal range (over -
heated).
SETTING THE FOLLOWING DISTANCE IN
ACC
The specified following distance for ACC can be
set by varying the distance setting between four
bars (longest), three bars (long), two bars
(medium) and one bar (short). Using this
distance setting and the vehicle speed, ACC
calculates and sets the distance to the vehicle
ahead. This distance setting displays in the
instrument cluster display.
Distance Settings

To increase the distance setting, push the
Distance Setting Increase button and release.
Each time the button is pushed, the distance
setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting Decrease button and release.
Each time the button is pushed, the distance
setting decreases by one bar (shorter). If there is no vehicle ahead, the vehicle will
maintain the set speed. If a slower moving
vehicle is detected in the same lane, the
instrument cluster displays the ACC Set with
Target Indicator Light icon, and the system
adjusts vehicle speed automatically to maintain
the distance setting, regardless of the set
speed.
The vehicle will then maintain the set distance
until:
The vehicle ahead accelerates to a speed
above the set speed.
The vehicle ahead moves out of your lane or
view of the sensor.
The distance setting is changed.
The system disengages. (Refer to the infor
-
mation on ACC Activation).
The maximum braking applied by ACC is limited;
however, the driver can always apply the brakes
manually, if necessary.
NOTE:
The brake lights will illuminate whenever the
ACC system applies the brakes.
1 — Longest Distance Setting (Four Bars)
2 — Long Distance Setting (Three Bars)
3 — Medium Distance Setting (Two Bars)
4 — Short Distance Setting (One Bar)
5

20_WD_OM_EN_USC_t.book Page 213

214STARTING AND OPERATING
A Proximity Warning will alert the driver if ACC
predicts that its maximum braking level is not
sufficient to maintain the set distance. If this
occurs, a visual alert “BRAKE” will flash in the
instrument cluster display and a chime will
sound while ACC continues to apply its
maximum braking capacity.

Brake Alert

NOTE:
The “BRAKE!” screen in the instrument cluster
display is a warning for the driver to take action
and does not necessarily mean that the
Forward Collision Warning system is applying
the brakes autonomously.OVERTAKE AID
When driving with ACC engaged and following a
vehicle, the system will provide an additional
acceleration up to the ACC set speed to assist in
passing the vehicle. This additional acceleration
is triggered when the driver utilizes the left turn
signal and will only be active when passing on
the left hand side.
ACC OPERATION AT STOP
If the ACC system brings your vehicle to a
standstill while following a target vehicle, if the
target vehicle starts moving within two seconds
of your vehicle coming to a standstill, your
vehicle will resume motion without the need for
any driver action.
If the target vehicle does not start moving within
two seconds of your vehicle coming to a
standstill, the ACC with Stop system will cancel
and the brakes will release. A cancel message
will display on the instrument cluster display
and produce a warning chime. Driver
intervention will be required at this moment. While ACC with Stop is holding your vehicle at a
standstill, if the driver seat belt is unbuckled or
the driver door is opened, the ACC with Stop
system will cancel and the brakes will release.
A cancel message will display on the instrument
cluster display and produce a warning chime.
Driver intervention will be required at this
moment.
ADAPTIVE CRUISE CONTROL (ACC)
M
ENU
The instrument cluster display will show the
current Adaptive Cruise Control (ACC) system
settings. The instrument cluster display is
located in the center of the instrument cluster.
The information it displays depends on ACC
system status.
WARNING!
When the ACC system is resumed, the driver
must ensure that there are no pedestrians,
vehicles or objects in the path of the vehicle.
Failure to follow these warnings can result in
a collision and death or serious personal
injury.

20_WD_OM_EN_USC_t.book Page 214

218STARTING AND OPERATING
Lane Changing
ACC may not detect a vehicle until it is
completely in the lane in which you are
traveling. In the illustration shown, ACC has not
yet detected the vehicle changing lanes and it
may not detect the vehicle until it's too late for
the ACC system to take action. ACC may not
detect a vehicle until it is completely in the lane.
There may not be sufficient distance to the
lane-changing vehicle. Always be attentive and
ready to apply the brakes if necessary.

Lane Changing Example

Narrow Vehicles
Some narrow vehicles traveling near the outer
edges of the lane or edging into the lane are not
detected until they have moved fully into the
lane. There may not be sufficient distance to the
vehicle ahead.
Narrow Vehicle Example

Stationary Objects And Vehicles
ACC does not react to stationary objects and
stationary vehicles. For example, ACC will not
react in situations where the vehicle you are
following exits your lane and the vehicle ahead
is stopped in your lane. Always be attentive and
ready to apply the brakes if necessary.
Stationary Object And Stationary Vehicle Example

20_WD_OM_EN_USC_t.book Page 218

STARTING AND OPERATING227
PARKSENSE FRONT AND REAR PARK ASSIST
— IF EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the distance
between the rear and/or front fascia and a
detected obstacle when backing up or moving
forward (e.g. during a parking maneuver). If your vehicle is equipped with an automatic
transmission, the vehicle brakes may be
automatically applied and released when
performing a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
NOTE:
The driver can disable the automatic braking
function by turning ParkSense off via the
ParkSense switch. The driver can also over
-
ride automatic braking by changing the gear
or by pressing the gas pedal over 90% of its
capacity during the braking event.
Automatic brakes are not available if the
vehicle is in 4WD Low.
Automatic brakes will not be available if there
is a faulted condition detected with the Park -
Sense Park Assist system or the Braking
System Module.
The automatic braking function may only be
applied if the vehicle deceleration is not
enough to avoid colliding with a detected
obstacle.
The automatic braking function may not be
applied fast enough for obstacles that move
toward the rear of the vehicle from the left
and/or right sides.
The automatic braking function can be
enabled/disabled from the Customer
Programmable Features section of the Ucon -
nect System.
ParkSense will retain its last known configu -
ration state for the automatic braking func -
tion through ignition cycles.
The automatic braking function is intended to
assist the driver in avoiding possible collisions
with detected obstacles when backing up in
REVERSE gear.
NOTE:
The driver is always responsible for
controlling the vehicle.
The system is designed to assist the driver
and not to substitute the driver.
The driver must stay in full control of the
vehicle's acceleration and braking and is
responsible for the vehicle's movements.
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.
