200STARTING AND OPERATING
The LOW RANGE position is designed for loose,
slippery road surfaces only. Driving in the LOW
RANGE position on dry hard surfaced roads may
cause increased tire wear and damage to the
driveline components.
Transfer Case Position Indicator Messages
The Transfer Case Position Indicator messages
(AWD AUTO and LOW RANGE) are located in the
instrument cluster and indicate the current and
desired transfer case selection. Refer to
“Instrument Cluster Display” in “Getting To
Know Your Instrument Panel” for further
information. When you select a different
transfer case position, the position indicator
lights will do the following:
If All Shift Conditions Are Met:

1. The current position indicator light will turn
off.

2. The selected position indicator light will flash until the transfer case completes the
shift.
3. When the shift is complete, the indicator light for the selected position will stop
flashing and remain on. If shift conditions are not met, one or more of
the following events may occur:

1. The indicator light for the current position
will remain on.

2. The newly selected position indicator light will continue to flash.
3. The transfer case will not shift.
NOTE:
Before retrying a selection, make certain that all
the necessary requirements for selecting a new
transfer case position have been met. To retry
the selection, turn the control knob back to the
current position, wait five seconds, and retry
selection. To find the shift requirements, refer
to the "Shifting Procedure" for your transfer
case, located in this section.
The “SERV AWD” Warning Light monitors the
electronic shift all-wheel drive system. If this
light remains on after engine start up or
illuminates during driving, it means that the
all-wheel drive system is not functioning
properly and that service is required. NOTE:
Do not attempt to make a shift while only the
front or rear wheels are spinning. This could
cause damage to driveline components.
When operating your vehicle in LOW RANGE, the
engine speed is approximately three times that
of the AWD AUTO position at a given road speed.
Take care not to overspeed the engine and do
not exceed 25 mph (40 km/h).
Proper operation of all-wheel drive vehicles
depends on tires of equal size, type and
circumference on each wheel. Any difference in
tire size can cause damage to the transfer case.
Because all-wheel drive provides improved
traction, there is a tendency to exceed safe
turning and stopping speeds. Do not go faster
than road conditions permit.
WARNING!
Always engage the parking brake when
powering down the vehicle if the “SERV AWD
Warning Light” is illuminated. Not engaging
the parking brake may allow the vehicle to roll
which may cause personal injury.

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.

216STARTING AND OPERATING
If the sensor or front end of the vehicle is
damaged due to a collision, see an autho -
rized dealer for service.
Do not attach or install any accessories near
the sensor, including transparent material or
aftermarket grilles. Doing so could cause an
ACC system failure or malfunction.
When the condition that deactivated the system
is no longer present, the system will return to
the “Adaptive Cruise Control Off” state and will
resume function when reactivated.
NOTE:
If the “ACC/FCW Unavailable Wipe Front
Radar Sensor” message occurs frequently
(e.g. more than once on every trip) without
any snow, rain, mud, or other obstruction,
have the radar sensor realigned at an autho -
rized dealer.
Installing a snow plow, front-end protector,
an aftermarket grille or modifying the grille is
not recommended. Doing so may block the
sensor and inhibit ACC/FCW operation.
“Clean Front Windshield” Warning
The “ACC/FCW Limited Functionality Clean
Front Windshield” warning will display and a
chime will sound when conditions temporarily
limit system performance. This most often
occurs at times of poor visibility, such as in
snow or heavy rain and fog. The ACC system
may also become temporarily blinded due to
obstructions, such as mud, dirt, or ice on
windshield and fog on the inside of glass. In
these cases, the instrument cluster display will
display “ACC/FCW Limited Functionality Clean
Front Windshield” and the system will have
degraded performance.
The “ACC/FCW Limited Functionality Clean
Front Windshield” message can sometimes be
displayed while driving in adverse weather
conditions. The ACC/FCW system will recover
after the vehicle has left these areas. Under
rare conditions, when the camera is not
tracking any vehicles or objects in its path this
warning may temporarily occur.
If weather conditions are not a factor, the driver
should examine the windshield and the camera
located on the back side of the inside rear view
mirror. They may require cleaning or removal of
an obstruction. When the condition that created limited
functionality is no longer present, the system
will return to full functionality.
NOTE:
If the “ACC/FCW Limited Functionality Clean
Front Windshield” message occurs frequently
(e.g. more than once on every trip) without any
snow, rain, mud, or other obstruction, have the
windshield and forward facing camera
inspected at an authorized dealer.
Service ACC/FCW Warning
If the system turns off, and the instrument
cluster displays “ACC/FCW Unavailable Service
Required” or “Cruise/FCW Unavailable Service
Required”, there may be an internal system
fault or a temporary malfunction that limits ACC
functionality. Although the vehicle is still
drivable under normal conditions, ACC will be
temporarily unavailable. If this occurs, try
activating ACC again later, following an ignition
cycle. If the problem persists, see an authorized
dealer.

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.

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.
