Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine, transmission, Power Trans-
fer Unit and Rear Drive Module) to assure they have not
been contaminated. Contaminated fluids and lubricants
(milky, foamy in appearance) should be flushed/changed
as soon as possible to prevent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the 4WD system to the appropriate terrain
mode, using 4WD LOW if necessary. Refer to “Four-
Wheel Drive Operation” in “Starting And Operating” for
further information. Do not shift to a lower gear than
necessary to maintain headway. Over-revving the engine
can spin the wheels and traction will be lost.Avoid abrupt downshifts on icy or slippery roads be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the 4WD System to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose headway while climbing a
steep hill, allow your vehicle to come to a stop and
immediately apply the brakes. Restart the engine and shift
to REVERSE. Back slowly down the hill allowing the
compression braking of the engine to help regulate your
speed. If the brakes are required to control vehicle speed,
apply them lightly and avoid locking or skidding the tires.
508 STARTING AND OPERATING
WARNING!
If the engine stalls or you lose headway or cannot
make it to the top of a steep hill or grade, never
attempt to turn around. To do so may result in
tipping and rolling the vehicle. Always back straight
down a hill in REVERSE gear carefully. Never back
down a hill in NEUTRAL using only the brake.
NOTE: Remember, never drive diagonally across a hill -
drive straight up or down.
If the wheels start to slip as you approach the crest of a
hill, ease off the accelerator and maintain headway by
turning the front wheels slowly left and right. This may
provide a fresh “bite” into the surface and will usually
provide traction to complete the climb.
Traction Downhill
Shift the transmission into a low gear and the 4WD
System to 4WD LOW range or Select Hill Descent
Control if equipped (refer to Electronic Brake Control
System in this section for further information). Let the
vehicle go slowly down the hill with all four wheels
turning against engine compression drag. This will per-
mit you to control the vehicle speed and direction.
When descending mountains or hills, repeated braking
can cause brake fade with loss of braking control. Avoid
repeated heavy braking by downshifting the transmis-
sion whenever possible.
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.
5
STARTING AND OPERATING 509
•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 components, steering, and sus-
pension. 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.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.
• 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 imbalance and freeing the wheels of it will
correct the situation.
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
510 STARTING AND OPERATING
light efforts while parking and good feel while driving. If
the electric steering system experiences a fault that
reduces assist or prevents the vehicle from providing
assist, you will still have the ability to steer the vehicle
manually.
WARNING!
Continued operation with reduced assist could pose
a safety risk to yourself and others. Service should be
obtained as soon as possible.If the “SERVICE POWER STEERING OR
POWER STEERING ASSIST OFF - SERVICE
SYSTEM” message and a steering wheel icon
are displayed on the EVIC/DID screen, it indi-
cates that the vehicle needs to be taken to the dealer for
service. It is likely the vehicle has lost power steering
assistance. Refer to “Electronic Vehicle Information (EVIC) or
Driver Information Display (DID)” in “Under-
standing Your Instrument Panel” for further information.
If the “POWER STEERING SYSTEM HOT - PERFOR-
MANCE MAY BE LIMITED” message and an icon are
displayed on the EVIC/DID screen, it indicates that
extreme steering maneuvers may have occurred, which
caused an over temperature condition in the power
steering system. You will lose power steering assistance
momentarily until the over temperature condition no
longer exists. Once driving conditions are safe, then pull
over and let vehicle idle for a few moments until the light
turns off. Refer to “Electronic Vehicle Information
(EVIC)/Driver Information Display (DID)” in “Under-
standing Your Instrument Panel” for further information.5
STARTING AND OPERATING 511
The park brake will release automatically when the
ignition switch is ON, the transmission is in DRIVE or
REVERSE, the driver seat belt is buckled, and an attempt
is made to drive away.
To release the park brake manually, the ignition switch
must be in the ON/RUN position. Put your foot on the
brake pedal, then push the park brake switch down
momentarily. You may hear a slight whirring sound from
the back of the car while the parking brake disengages.
You may also notice a small amount of movement in the
brake pedal. Once the park brake is fully disengaged, The
BRAKE warning lamp in the instrument cluster and the
LED indicator on the switch will extinguish.NOTE:
When parking on a hill, it is important to turn the
front wheels toward the curb on a downhill grade and
away from the curb on an uphill grade. Apply the park
brake before placing the shift lever in PARK, otherwise
the load on the transmission locking mechanism may
make it difficult to move the shift lever out of PARK. The
parking brake should always be applied whenever the
driver is not in the vehicle.
WARNING!
• Never use the PARK position as a substitute for the
parking brake. Always apply the parking brake
fully when parked to guard against vehicle move-
ment and possible injury or damage.
• When leaving the vehicle, always remove the Key
Fob from the ignition and lock your vehicle.

514 STARTING AND OPERATING
ELECTRONIC BRAKE CONTROL SYSTEM
Your vehicle is equipped with an advanced Electronic
Brake Control system (EBC). This system includes Elec-
tronic Brake Force Distribution (EBD), Anti-Lock Brake
System (ABS), Brake Assist System (BAS), Hill Start
Assist (HSA), Traction Control System (TCS), Electronic
Stability Control (ESC), and Electronic Roll Mitigation
(ERM). These systems work together to enhance both
vehicle stability and control in various driving condi-
tions.
Your vehicle may also be equipped with Trailer Sway
Control (TSC), Ready Alert Braking (RAB), Rain Brake
Support (RBS), Dynamic Steering Torque (DST), Hill
Descent Control (HDC), and Selec-Speed Control (SSC).
Electronic Brake Force Distribution (EBD)
This function manages the distribution of the braking
torque between the front and rear axles by limiting
braking pressure to the rear axle. This is done to preventoverslip of the rear wheels to avoid vehicle instability,
and to prevent the rear axle from entering ABS before the
front axle.
Brake System Warning Light
The red “Brake System Warning Light” will turn on when
the ignition switch is turned to the ON position and may
stay on for as long as four seconds.
If the “Brake System Warning Light” remains on or
comes on while driving, it indicates that the brake system
is not functioning properly and that immediate service is
required. If the “Brake System Warning Light” does not
come on when the ignition switch is turned to the ON
position, have the light repaired as soon as possible.
Anti-Lock Brake System (ABS)
The Anti-Lock Brake System (ABS) provides increased
vehicle stability and brake performance under most
520 STARTING AND OPERATING
braking conditions. The system automatically prevents
wheel lock, and enhances vehicle control during braking.
The ABS performs a self-check cycle to ensure that the
ABS is working properly each time the vehicle is started
and driven. During this self-check you may hear a slight
clicking sound as well as some related motor noises.
ABS is activated during braking when the system detects
one or more wheels begins to lock. Road conditions such as
ice, snow, gravel, bumps, railroad tracks, loose debris, or
panic stops may increase the likelihood of ABS activation(s).
You also may experience the following when ABS activates:
•The ABS motor noise (it may continue to run for a
short time after the stop).
• The clicking sound of solenoid valves.
• Brake pedal pulsations.
• A slight drop of the brake pedal at the end of the stop. These are all normal characteristics of ABS.
WARNING!
•
The ABS contains sophisticated electronic equip-
ment that may be susceptible to interference
caused by improperly installed or high output
radio transmitting equipment. This interference
can cause possible loss of anti-lock braking capa-
bility. Installation of such equipment should be
performed by qualified professionals.
• Pumping of the Anti-Lock Brakes will diminish
their effectiveness and may lead to a collision.
Pumping makes the stopping distance longer. Just
press firmly on your brake pedal when you need to
slow down or stop.
• The ABS cannot prevent the natural laws of phys-
ics from acting on the vehicle, nor can it increase

STARTING AND OPERATING 521
WARNING!
•If you use a trailer brake controller with your
trailer, the trailer brakes may be activated and
deactivated with the brake switch. If so, there may
not be enough brake pressure to hold both the
vehicle and the trailer on a hill when the brake
pedal is released. In order to avoid rolling down an
incline while resuming acceleration, manually ac-
tivate the trailer brake or apply more vehicle brake
pressure prior to releasing the brake pedal.
• HSA is not a parking brake. Always apply the
parking brake fully when leaving your vehicle.
Also, be certain to leave the transmission in PARK.
• Failure to follow these warnings can result in a
collision or serious personal injury.
Disabling And Enabling HSA
This feature can be turned on or turned off. To change the
current setting, proceed as follows:
• For vehicles equipped with the Electronic Vehicle
Information Center (EVIC) or Driver Information Dis-
play (DID), refer to “Electronic Vehicle Information
Center (EVIC)” or “Driver Information Display (DID)”
in “Understanding Your Instrument Panel” for further
information.
• If disabling HSA using Uconnect Settings, refer to
“Uconnect Settings” in “Understanding Your Instru-
ment Panel” for further information.
For vehicles not equipped with the EVIC/DID, perform
the following steps:
1. Center the steering wheel (front wheels pointing straight forward).
