STARTING AND OPERATING171
Selection Of The Maneuver Side
Use the direction indicators to choose the direction
that you want to perform the maneuver. Use the
right arrow indicator to perform the maneuver to
the right side and use the left arrow indicator to
perform the maneuver to the left.
During the maneuver, the system instructs the
driver to shift to REVERSE, and operate the turn
signal in the direction you want to exit. Let go of the
steering wheel and use the brake or accelerator
pedals as instructed, while the system handles the
steering automatically for exiting the parking
space. If the driver continues to carry out a
voluntary or involuntary action on the steering
wheel during the exit maneuver (touching or
holding the steering wheel to prevent its
movement), the maneuver will be interrupted.
Shift To Reverse Then Move Backward Shift To Drive Then Move Forward
End Of Maneuver
The semi-automatic maneuver ends when the
display shows the message of a completed
maneuver. At the end of the maneuver, the system
gives back the vehicle control to the driver.
ACTIVE LANE MANAGEMENT SYSTEM —
IF EQUIPPED
ACTIVE LANE MANAGEMENT OPERATION
The Active Lane Management (ALM) system uses a
forward facing camera to detect lane markings or
road edges and to measure vehicle position within
the lane boundaries. It also uses the Blind Spot
Monitoring (BSM) sensors to detect vehicles in
adjacent lanes while the driver is preparing to
change lanes. The system is operational at speeds above 37 mph
(60 km/h) and below 112 mph (180 km/h).
When both lane markings are detected, and the
vehicle approaches (or crosses) the lane marking
with no turn signal applied, and the blind spot zone
is not occupied, the ALM system provides warnings
to prompt the driver to remain within the lane
boundaries. These warnings include a visual
warning in the instrument cluster along with
steering assist torque (if configured in Uconnect
Settings).
If the driver crosses the lane marking, the system
will either guide the vehicle back to the center of
the lane, provide a vibration in the steering wheel,
or both, depending on radio settings.
When both lane markings are detected, and the
driver uses the turn signal to indicate a lane
change, and a vehicle is detected in the BSM zone
on that side of the vehicle, the ALM system
provides a warning in the form of steering assist
and/or steering vibration (depending on radio
settings) to guide the vehicle back to the center of
the lane.NOTE:
The system will suppress visual warnings,
steering vibration (if selected in radio settings),
and steering assistance (if selected in radio
settings) when the driver activates the turn
signal, the blind spot zone is clear of vehicles,
and a lane change is occurring.

172STARTING AND OPERATING
If the Blind Spot Monitoring (BSM) system
detects a vehicle in the adjacent lane, and the
turn signal is applied in that direction, the BSM
LED on the mirror will flash. If the driver
continues to attempt the lane change, steering
wheel torque will be provided to keep the
vehicle within its lane markings.
The driver may manually override the steering
assist warning by applying force to the steering
wheel at any time.
When only a single lane marking is detected and
the driver drifts across the lane marking (no turn
signal applied), the Active Lane Management
system provides a visual warning in the instrument
cluster, as well as a steering assist torque (if
configured in Uconnect Settings), to prompt the
driver to remain within the lane boundaries. If the
driver continues to drift out of the lane, the system
provides a flashing visual warning through the
instrument cluster display as well as a haptic
steering wheel vibration (if configured in Uconnect
Settings) when the vehicle crosses the lane
boundary.
NOTE:When operating conditions have been met, the
Active Lane Management system will monitor if the
driver’s hands are on the steering wheel and
provides an audible and visual warning to the
driver if removed. The system will cancel if the
driver does not return their hands to the wheel.

The Active Lane Management system will indicate
the current lane drift condition through the
instrument cluster display.
When the system is on, the lane lines are gray
when both of the lane boundaries have not been
detected.
System On (Gray Lines)
Left Lane Departure — Only Left Lane Detected
When the system is on and only the left lane
marking has been detected, and the system is
ready to provide visual warnings in the instru-
ment cluster display and a vibration and/or
steering assist warning in the steering wheel if a
lane departure occurs, the left lane line will be
green.
When the system senses the lane line has been
approached (but not crossed), the left lane line
will change to solid yellow and the system will
provide a haptic steering wheel vibration and/or
steering assist torque (if programmed in
Uconnect Settings).
When the system senses the lane line is being
crossed, the left lane line will change to flashing
yellow.

174STARTING AND OPERATING
NOTE:
The Active Lane Management system operates
with similar behavior for a right lane departure.
If the turn signal is activated, and the vehicle
begins to depart the lane at the same time the
Blind Spot Monitoring (BSM) system detects
another vehicle in the BSM zones, the system
will provide a haptic steering wheel vibration
and/or steering assist torque (if programmed in
Uconnect Settings).

PARKVIEW REAR BACK UP CAMERA
Your vehicle is equipped with the ParkView Rear
Back Up Camera that allows you to see an
on-screen image of the rear surroundings of your
vehicle whenever the gear selector is put into
REVERSE. The image will be displayed on the
Uconnect display screen along with a caution note
to “Check Entire Surroundings” across the top of
the screen. After five seconds this note will
disappear. The ParkView camera is located on the
rear of the vehicle above the rear license plate.
When the vehicle is shifted out of REVERSE with
camera delay turned off, the rear camera mode is
exited and the previous screen appears. Manual Activation Of The Back Up Camera
1. Press the Vehicle button located on the
bottom of the Uconnect display and then
select the Controls menu.
2. Press the Back Up Camera icon to turn the Rear View Camera system on.
NOTE:The ParkView Rear Back Up Camera has program -
mable modes of operation that may be selected
through the Uconnect system Ú page 204.
When the vehicle is shifted out of REVERSE with
camera delay turned off, the rear camera mode is
exited and the previous screen appears. When the
vehicle is shifted out of REVERSE with camera delay
turned on, the camera image will continue to be
displayed for up to 10 seconds unless the following
conditions occur: the vehicle speed exceeds 8 mph
(13 km/h), the vehicle is shifted into PARK, the
vehicle’s ignition is placed in the OFF position, or the
touchscreen X button to disable the display of the
Rear View Camera is pressed.
When enabled, active guidelines are overlaid on
the image to illustrate the width of the vehicle and
its projected backup path based on the steering
wheel position. A dashed center line overlay
indicates the center of the vehicle to assist with

202STARTING 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, partic -
ularly on the chassis, drivetrain components,
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 mate -
rial can cause a wheel imbalance 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.

250SAFETY
ELECTRONIC BRAKE CONTROL (EBC)
S
YSTEM
If applicable, refer to the “Hybrid Supplement” for
additional information.
Your vehicle is equipped with an advanced EBC
system. This system includes the Anti-Lock Brake
System (ABS), Brake Assist System (BAS),
Electronic Brake Force Distribution (EBD), Electronic Roll Mitigation (ERM), Electronic
Stability Control (ESC), Hill Start Assist (HSA), and
Traction Control System (TCS). These systems work
together to enhance both vehicle stability and
control in various driving conditions.
Your vehicle may also be equipped with Dynamic
Steering Torque (DST), Rain Brake Support (RBS),
Ready Alert Braking (RAB), and Trailer Sway
Control (TSC).
Brake Assist System (BAS)
The BAS is designed to optimize the vehicle’s
braking capability during emergency braking
maneuvers. The system detects an emergency
braking situation by sensing the rate and amount
of brake application and then applies optimum
pressure to the brakes. This can help reduce
braking distances. The BAS complements the
Anti-Lock Brake System (ABS). Applying the brakes
very quickly results in the best BAS assistance. To
receive the benefit of the system, you must apply
continuous braking pressure during the stopping
sequence (do not “pump” the brakes). Do not
reduce brake pedal pressure unless braking is no
longer desired. Once the brake pedal is released,
the BAS is deactivated.
Brake System Warning Light
The red Brake System Warning Light will turn on
when the ignition is placed in the ON/RUN mode
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
is placed in the ON/RUN mode, have the light
repaired as soon as possible.
WARNING!
Before exiting a vehicle, always come to a
complete stop, then shift the automatic trans
-
mission into PARK and apply the parking
brake.
Always make sure the keyless ignition node is
in the OFF position, key fob is removed from
the vehicle and vehicle is locked.
Never leave children alone in a vehicle, or with
access to an unlocked vehicle. Leaving chil -
dren in a vehicle unattended is dangerous for
a number of reasons. A child or others could
be seriously or fatally injured. Children should
be warned not to touch the parking brake,
brake pedal or the gear selector.
Do not leave children or animals inside parked
vehicles in hot weather. Interior heat buildup
may cause serious injury or death.
WARNING!
The Brake Assist System (BAS) cannot prevent
the natural laws of physics from acting on the
vehicle, nor can it increase the traction afforded
by prevailing road conditions. BAS cannot
prevent collisions, including those resulting from
excessive speed in turns, driving on very slippery
surfaces, or hydroplaning. The capabilities of a
BAS-equipped vehicle must never be exploited in
a reckless or dangerous manner, which could
jeopardize the user's safety or the safety of
others.
23_WL_OM_EN_USC_t.book Page 250
Page 253 of 424
SAFETY251
Electronic Brake Force Distribution (EBD)
EBD 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
prevent overslip of the rear wheels to avoid vehicle
instability, and to prevent the rear axle from
entering ABS before the front axle.
Electronic Roll Mitigation (ERM)
ERM anticipates the potential for wheel lift by
monitoring the driver’s steering wheel input and
the speed of the vehicle. When ERM determines
that the rate of change of the steering wheel angle
and vehicle’s speed are sufficient to potentially
cause wheel lift, it then applies the appropriate
brake and may also reduce engine power to lessen
the chance that wheel lift will occur. ERM can only
reduce the chance of wheel lift occurring during
severe or evasive driving maneuvers; it cannot
prevent wheel lift due to other factors, such as
road conditions, leaving the roadway, or striking
objects or other vehicles.
NOTE:ERM is disabled any time the ESC is in “Full Off”
mode (if equipped). See Ú page 251 for a
complete explanation of the available ESC modes.
Electronic Stability Control (ESC)
ESC enhances directional control and stability of
the vehicle under various driving conditions. ESC
corrects for oversteering or understeering of the
vehicle by applying the brake of the appropriate
wheel(s) to assist in counteracting the following
conditions. Engine power may also be reduced to
help the vehicle maintain the desired path.
Oversteer — when the vehicle is turning more
than appropriate for the steering wheel position.
Understeer — when the vehicle is turning less
than appropriate for the steering wheel position.
ESC uses sensors in the vehicle to determine the
vehicle path intended by the driver and compares
it to the actual path of the vehicle. When the actual
path does not match the intended path, ESC
applies the brake of the appropriate wheel to
assist in counteracting the oversteer or understeer
condition.
The ESC Activation/Malfunction Indicator Light
located in the instrument cluster will start to flash
as soon as the ESC system becomes active. The
ESC Activation/Malfunction Indicator Light also
flashes when the Traction Control System (TCS) is
active. If the ESC Activation/Malfunction Indicator
Light begins to flash during acceleration, ease up
on the accelerator and apply as little throttle as
possible. Be sure to adapt your speed and driving
to the prevailing road conditions.
WARNING!
Many factors, such as vehicle loading, road
conditions and driving conditions, influence the
chance that wheel lift or rollover may occur. ERM
cannot prevent all wheel lift or rollovers,
especially those that involve leaving the roadway
or striking objects or other vehicles. The
capabilities of an ERM-equipped vehicle must
never be exploited in a reckless or dangerous
manner which could jeopardize the user's safety
or the safety of others.

Disabling And Enabling HSA
This feature can be turned on or turned off. To
change the current setting, proceed as follows:
If disabling HSA using your instrument cluster
display, see Ú page 98 for further information.
If disabling HSA using Uconnect Settings, see
Úpage 204 for further information.
Towing With HSA
HSA will also provide assistance to mitigate roll
back while towing a trailer.
Rain Brake Support (RBS)
RBS may improve braking performance in wet
conditions. It will periodically apply a small amount
of brake pressure to remove any water buildup on
the front brake rotors. It functions when the
windshield wipers are in LO or HI speed. When RBS
is active, there is no notification to the driver and
no driver interaction is required.
Ready Alert Braking (RAB)
RAB may reduce the time required to reach full
braking during emergency braking situations. It
anticipates when an emergency braking situation
may occur by monitoring how fast the throttle is
released by the driver. The Electronic Brake
Controller (EBC) will prepare the brake system for
a panic stop.
Selec-Speed Control (SSC) — If Equipped
SSC is intended for off-road driving in
4WD Low only. SSC maintains vehicle
speed by actively controlling engine
torque and brakes.
SSC has three states:
1. Off (feature is not enabled and will not activate)
2. Enabled (feature is enabled and ready but activation conditions are not met, or driver is
actively overriding with brake or throttle
application)
3. Active (feature is enabled and actively controlling vehicle speed)
WARNING!
There may be situations where the Hill Start
Assist (HSA) will not activate and slight rolling
may occur, such as on minor hills or with a
loaded vehicle, or while pulling a trailer. HSA is
not a substitute for active driving involvement. It
is always the driver’s responsibility to be
attentive to distance to other vehicles, people,
and objects, and most importantly brake
operation to ensure safe operation of the vehicle
under all road conditions. Your complete
attention is always required while driving to
maintain safe control of your vehicle. Failure to
follow these warnings can result in a collision or
serious personal injury.
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 accel -
eration, manually activate 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 exiting your vehicle.
Also, be certain to place the transmission in
PARK.
Failure to follow these warnings can result in a
collision or serious personal injury.

PERIODIC SAFETY CHECKS YOU SHOULD
M
AKE OUTSIDE THE VEHICLE
Tires
Examine tires for excessive tread wear and uneven
wear patterns. Check for stones, nails, glass, or
other objects lodged in the tread or sidewall.
Inspect the tread for cuts and cracks. Inspect
sidewalls for cuts, cracks, and bulges. Check the
lug nut/bolt torque for tightness. Check the tires
(including spare) for proper cold inflation pressure.
Lights
Have someone observe the operation of brake
lights and exterior lights while you work the
controls. Check turn signal and high beam
indicator lights on the instrument panel.
Door Latches
Check for proper closing, latching, and locking.
Fluid Leaks
Check area under the vehicle after overnight
parking for fuel, coolant, oil, or other fluid leaks.
Also, if gasoline fumes are detected or if fuel or
brake fluid leaks are suspected, the cause should
be located and corrected immediately.
EXHAUST GAS
NEVER place any objects under the floor mat
(e.g., towels, keys, etc.). These objects could
change the position of the floor mat and may
cause interference with the accelerator,
brake, or clutch pedals.
If the vehicle carpet has been removed and
re-installed, always properly attach carpet to
the floor and check the floor mat fasteners are
secure to the vehicle carpet. Fully depress
each pedal to check for interference with the
accelerator, brake, or clutch pedals then
re-install the floor mats.
It is recommended to only use mild soap and
water to clean your floor mats. After cleaning,
always check your floor mat has been properly
installed and is secured to your vehicle using
the floor mat fasteners by lightly pulling mat.
WARNING!
WARNING!
Exhaust gases can injure or kill. They contain
carbon monoxide (CO), which is colorless and
odorless. Breathing it can make you
unconscious and can eventually poison you. To
avoid breathing (CO), follow these safety tips:
Do not run the engine in a closed garage or in
confined areas any longer than needed to
move your vehicle in or out of the area.
If you are required to drive with the trunk/lift -
gate/rear doors open, make sure that all
windows are closed and the climate control
BLOWER switch is set at high speed. DO NOT
use the recirculation mode.
If it is necessary to sit in a parked vehicle with
the engine running, adjust your heating or
cooling controls to force outside air into the
vehicle. Set the blower at high speed.

SERVICING AND MAINTENANCE351
AUTOMATIC TRANSMISSION
Special Additives
The manufacturer strongly recommends against
using any special additives in the transmission.
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.
Avoid using transmission sealers as they may
adversely affect seals.
Fluid Level Check
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
immediately to have the transmission fluid level
checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage.
Fluid And Filter Changes
Routine fluid and filter changes are not required.
However, change the fluid and filter if the fluid
becomes contaminated (with water, etc.), or if the
transmission is disassembled for any reason.
Selection Of Lubricant
It is important to use the proper transmission fluid
to ensure optimum transmission performance and
life. Use only the manufacturer's specified
transmission fluid Úpage 402. It is important to
maintain the transmission fluid at the correct level
using the recommended fluid.
NOTE:No chemical flushes should be used in any trans -
mission; only the approved lubricant should be
used.
FRONT/REAR AXLE FLUID
For normal service, periodic fluid level checks are
not required. When the vehicle is serviced for other
reasons the exterior surfaces of the axle assembly
should be inspected. If gear oil leakage is
suspected inspect the fluid level.
Front Axle Fluid Level Check
The front axle oil level needs to be no lower than
1/8 inch (3 mm) below the bottom of the fill hole.
The front axle fill and drain plugs should be
tightened to 22 to 29 ft-lb (30 to 40 N·m).
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.
CAUTION!
Using a transmission fluid other than the
manufacturer’s recommended fluid may cause
deterioration in transmission shift quality and/or
torque converter shudder.
CAUTION!
Do not overtighten the plugs as it could damage
them and cause them to leak.
