NOTE:If damage to the windshield occurs, have the wind -
shield replaced by an authorized dealer as soon as
possible.
PARKSENSE FRONT/REAR PARK ASSIST
SYSTEM — IF EQUIPPED
The ParkSense Park Assist system provides visual
and audible indications of the distance between
the rear, and if equipped, the front fascia/bumper
and a detected obstacle when backing up or
moving forward (e.g. during a parking maneuver).
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 override
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 ParkSense
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 Program -
mable Features section of the Uconnect system.
ParkSense will retain its last known configura -
tion state for the automatic braking function
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 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.

166STARTING AND OPERATING
ParkSense Usage Precautions
Some conditions may influence the performance
of the Side Distance Warning system:
NOTE:
Ensure that the front and rear fascia/bumper
are free of snow, ice, mud, dirt and debris to
keep the ParkSense system operating properly.
Construction equipment, large trucks, and other
vibrations could affect the performance of
ParkSense.
When you turn ParkSense off, the message to
appear in the instrument cluster display will
read “PARKSENSE OFF.” Furthermore, once you
turn ParkSense off, it remains off until you turn
it on again, even if you cycle the ignition key.
ParkSense, when on, will reduce the volume of
the radio when it is sounding a tone.
Clean the ParkSense sensors regularly, taking
care not to scratch or damage them. The
sensors must not be covered with ice, snow,
slush, mud, dirt or debris. Failure to do so can
result in the system not working properly. The
ParkSense system might not detect an obstacle
behind or in front of the fascia/bumper, or it
could provide a false indication that an obstacle
is behind or in front of the fascia/bumper.
The presence of a tow hook without a trailer may
interfere with the correct operation of the
parking sensors. Before using the ParkSense system, it is recommended to remove the
removable tow hook ball assembly and any
attachments from the vehicle when it is not
used for towing operations.

PARKSENSE ACTIVE PARK ASSIST SYSTEM —
IF EQUIPPED

The ParkSense Active Park Assist system is
intended to assist the driver during parallel and
perpendicular parking maneuvers by identifying a
proper parking space, providing audible/visual
instructions, and controlling the steering wheel.
The ParkSense Active Park Assist system is
defined as “semi-automatic” since the driver
maintains control of the accelerator, gear selector
and brakes. Depending on the driver's parking
maneuver selection, the ParkSense Active Park
Assist system is capable of maneuvering a vehicle
into a parallel or a perpendicular parking space on
either side (i.e., driver side or passenger side).
WARNING!
Drivers must be careful when backing up even
when using ParkSense. Always check carefully
behind your vehicle, look behind you, and be
sure to check for pedestrians, animals, other
vehicles, obstructions, and blind spots before
backing up. You are 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 recom
-
mended that the ball mount and hitch ball
assembly be 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 vehicle 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
indication that an obstacle is behind the
vehicle.
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 recom -
mended that the driver looks over his/her
shoulder when using ParkSense.

23_WL_OM_EN_USC_t.book Page 166

STARTING AND OPERATING167
NOTE:
The driver is always responsible for controlling
the vehicle, responsible for any surrounding
objects, and must intervene as required.
The system is designed to assist the driver and
not to substitute the driver.
During a semi-automatic maneuver, if the driver
touches the steering wheel after being
instructed to remove their hands from the
steering wheel, the system will cancel, and the
driver will be required to manually complete the
parking maneuver.
The system may not work in all conditions (e.g.
environmental conditions such as heavy rain,
snow, etc., or if searching for a parking space
that has surfaces that will absorb the ultrasonic
sensor waves).
New vehicles from the dealership must have at
least 30 miles (48 km) accumulated before the
ParkSense Active Park Assist system is fully cali -
brated and performs accurately. This is due to
the system’s dynamic vehicle calibration to
improve the performance of the feature. The
system will also continuously perform the
dynamic vehicle calibration to account for differ -
ences such as over or under inflated tires and
new tires.
ENABLING AND DISABLING THE

The system may then instruct the driver to wait for
steering to complete before then instructing to
check the vehicle’s surroundings, and move
backward.
Several more gear shifts (DRIVE and REVERSE)
while keeping hands off of the steering wheel will
be instructed to the driver while checking the
vehicle’s surroundings before completing the
parking maneuver.
When the vehicle is in the parking position, the
maneuver is complete and the driver will be
instructed to check the vehicle's parking position,
then shift the vehicle into PARK. The message
“Active ParkSense Complete - Check Parking
Position” will be displayed momentarily.
NOTE:
It is the driver's responsibility to use the brake
and stop the vehicle. The driver should check
their surroundings and be prepared to stop the

even when using the ParkSense Active Park
Assist system. Always check carefully behind
and in front of your vehicle, look behind and in
front of you, and be sure to check for pedes -
trians, animals, other vehicles, obstructions,
and blind spots before backing up and moving
forward. You are 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 the ParkSense Active Park Assist
system, it is strongly recommended that the
ball mount and hitch ball assembly be discon -
nected 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

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.
4

23_WL_OM_EN_USC_t.book Page 171

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.

Lane Crossed (Flashing Yellow Line)

NOTE:The Active Lane Management system operates
with similar behavior for a right lane departure
when only the right lane marking has been
detected.
Left Lane Departure — Both Lanes Detected
When the system is on, the lane lines turn from
gray to green to indicate that both of the lane
markings have been detected. When both lane
markings have been detected, 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.
Lanes Sensed (Green Lines)

When the system senses a lane drift situation,
the left lane line turns solid yellow. At this time,
steering assist warning 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 Drift (Solid Yellow Line)
When the system senses the lane line is being
crossed, the left lane line changes from solid
yellow to flashing yellow (on/off). At this time,
vibration is applied to the steering wheel.
For example: If approaching the left side of the
lane, the steering wheel will turn to the right.
