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. The system works by identifying a proper
parking space, providing audible/visual instructions, and
controlling the steering wheel only, or the accelerator,
gear selector, brakes, and the steering wheel (if equipped
with the Fully Automated system). 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).
Two types of ParkSense Active Park Assist systems are
available:
Semi-Automatic ParkSense Active Park Assist
 ParkSense Automated Parking system Semi-Automatic ParkSense Active Park Assist —
If Equipped
The Semi-Automatic system detects parking spaces, and
controls the steering wheel only. The driver maintains
control of the accelerator, gear selector and brakes.
ParkSense Automated Parking — If Equipped
The Fully Automated system detects parking spaces, and
controls the accelerator, gear selector, brakes, and
steering wheel. In this mode, the system also provides
obstacle detection by providing visual and audible
warnings and automatic braking to avoid a collision.
If your vehicle is equipped with the Fully Automated
system, you can switch between Semi-Automatic and Fully
Automated mode in the Uconnect Settings
Úpage 197.
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 or Fully Automated
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.
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 respon -
sible 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 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 contin -
uous 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 Park -
Sense 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 Park -
Sense.
CAUTION!

23_WS_OM_EN_USC_t.book Page 160

STARTING AND OPERATING161
The system may not work in all conditions (e.g. environ -
mental 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 calibrated and
performs accurately. This is due to the system’s
dynamic vehicle calibration to improve the perfor -
mance of the feature. The system will also continuously
perform the dynamic vehicle calibration to account for
differences such as over or under inflated tires and
new tires.
ENABLING AND DISABLING THE
P
ARKSENSE ACTIVE PARK ASSIST

The ParkSense Active Park Assist system allows a
maximum number of shifts between DRIVE and REVERSE.
If the maneuver cannot be completed within the maximum
amount of shifts, the system will cancel and the
instrument cluster display will instruct the driver to
complete the maneuver manually. The ParkSense Active Park Assist system will only operate
and search for a parking space when the following
conditions are present:

Gear selector is in DRIVE
 Ignition is in the RUN position
 ParkSense Active Park Assist switch is activated
 All of the doors are closed
 Rear liftgate is closed
 Vehicle speed is less than 15 mph (25 km/h) during a

 The outer surface and the underside of the front and
rear fascias/bumpers are clean and clear of snow, ice,
mud, dirt or other obstruction
NOTE:
During a Semi-Automatic maneuver, if the vehicle is
driven above approximately 15 mph (25 km/h), the
instrument cluster display will instruct the driver to
slow down. If the vehicle is driven above approximately
18 mph (30 km/h), the system will cancel. The driver
must then reactivate the system by pushing the Park -
Sense Active Park Assist switch.
 During a Fully Automated maneuver, if the vehicle is
driven above approximately 25 mph (40 km/h), the
instrument cluster display will instruct the driver to

(Continued)
The system will then instruct the driver to remove hands
from the steering wheel and feet from the pedals. This
screen will be shown for a minimum of two seconds, or
until the driver releases the brake pedal.
When the parking sequence is initiated by the driver after
the previously described conditions are met, the Uconnect
system will display a Top View along with either a rear
camera view (if the vehicle is placed in REVERSE) or a
forward camera view (if the vehicle is placed in DRIVE).
The Top View will have integrated ParkSense arcs in the
image at the front and rear of the vehicle. The arcs will
change color from yellow to red corresponding the
distance zones to the oncoming object.
The system will then perform the parking maneuver. Once
the maneuver is complete, the vehicle will automatically
shift into PARK.
The system will display a “Complete!” message and
instruct the driver to release the Active Park Assist switch.
Once the Active Park Assist switch is released, a chime will
sound and the LED on the switch will turn off. After
approximately five seconds, the previous Uconnect screen
will display.
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 vehicle either when
instructed to, or when driver intervention is required.
 When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.
 The system will cancel the maneuver if the vehicle
speed exceeds 28 mph (40 km/h) during active
steering guidance into the parking space. The system
will provide a warning to the driver at 28 mph
(40 km/h) that tells them to slow down. The driver is
then responsible for completing the maneuver if the
system is canceled.
 If the system is canceled during the maneuver for any
reason, the driver must take control of the vehicle.
WARNING!
Drivers must be careful when performing parallel or
perpendicular parking maneuvers 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 pedestrians, animals, other vehicles, obstruc -
tions, 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 disconnected from
the vehicle when the vehicle is not used for towing.
Failure to do so can result in injury or damage to vehi -
cles or obstacles because the hitch ball will be much
closer to the obstacle than the rear fascia/bumper
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.

166STARTING AND OPERATING
Once active steering begins, a camera image will appear
in the Uconnect display with instructions that will display
for the duration of the maneuver.
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.

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 “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 vehicle either when
instructed to, or when driver intervention is required.
 It is the driver’s responsibility to use the brake and
accelerator during the Semi-Automatic parking
maneuver.
 When the system instructs the driver to remove their
hands from the steering wheel, the driver should check
their surroundings and begin to back up slowly.
 The ParkSense Active Park Assist system will allow a
maximum of eight shifts between DRIVE and REVERSE.
If the maneuver cannot be completed within eight
shifts, the system will cancel and the instrument
cluster display will instruct the driver to complete the
maneuver manually.
 The system will cancel the maneuver if the vehicle
speed exceeds 18 mph (30 km/h) during active
steering guidance into the parking space. The system
will provide a warning to the driver at 15 mph

STARTING AND OPERATING167
Parallel Park Exit
Enable the ParkSense Active Park Assist system by
pressing the ParkSense Active Park Assist switch. To
initiate a parking space exit maneuver, the vehicle must
be stopped, and the driver must press “Exit” on the
Uconnect display.
After the driver chooses a parallel park exit maneuver, the
system will then prompt the driver to choose an exit
method. The exit method options are Forward Left and
Forward Right.

Choose Exit Method

After an exit maneuver method has been selected, the
driver will be instructed to remove hands from the steering
wheel and shift into REVERSE.

Remove Hands From Wheel And Shift To Reverse

Release the steering wheel and use the brake and
accelerator pedals and gear selector as instructed, while
the system handles the steering automatically for exiting
the parking space. If the driver touches or holds the steering wheel
(voluntarily or not) during the exit maneuver, the
maneuver will be interrupted.
The Semi-Automatic maneuver ends when the display
shows the message of a completed maneuver. At the end
of the maneuver, the system gives vehicle control back 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).
CAUTION!
 The ParkSense Active Park Assist system 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 the
ParkSense Active Park Assist system 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 the ParkSense Active Park
Assist system.

242SAFETY
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 these 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.
ESC Operating Modes
Depending upon model and mode of operation, the ESC
system may have multiple operating modes.
ESC On
This is the normal operating mode for the ESC. Whenever
the vehicle is started, the ESC system will be in this mode.
This mode should be used for most driving conditions.
Alternate ESC modes should only be used for specific
reasons as noted in the following paragraphs.
Partial Off
This mode may be useful if the vehicle becomes stuck.
This mode may modify TCS and ESC thresholds for
activation, which allows for more wheel spin than normally
allowed.
To enter the “Partial Off” mode, momentarily push the ESC
OFF button and the ESC OFF Indicator Light will illuminate.
To turn the ESC on again, momentarily push the ESC OFF
button and the ESC OFF Indicator Light will turn off.
NOTE:For vehicles with multiple partial ESC modes, the push and
release of the button will toggle the ESC modes. Multiple
attempts may be required to return to "ESC On" mode.
WARNING!
 Electronic Stability Control (ESC) cannot prevent the
natural laws of physics from acting on the vehicle,
nor can it increase the traction afforded by prevailing
road conditions. ESC cannot prevent accidents,
including those resulting from excessive speed in
turns, driving on very slippery surfaces, or hydro -
planing. ESC also cannot prevent accidents resulting
from loss of vehicle control due to inappropriate
driver input for the conditions. Only a safe, attentive,
and skillful driver can prevent accidents. The capabil -
ities of an ESC equipped vehicle must never be
exploited in a reckless or dangerous manner which
could jeopardize the user’s safety or the safety of
others.
 Vehicle modifications, or failure to properly maintain
your vehicle, may change the handling characteris -
tics of your vehicle, and may negatively affect the
performance of the ESC system. Changes to the
steering system, suspension, braking system, tire
type and size or wheel size may adversely affect ESC
performance. Improperly inflated and unevenly worn
tires may also degrade ESC performance. Any vehicle
modification or poor vehicle maintenance that
reduces the effectiveness of the ESC system can
increase the risk of loss of vehicle control, vehicle
rollover, personal injury and death.

23_WS_OM_EN_USC_t.book Page 242

SAFETY247
Trailer Sway Control (TSC)
TSC uses sensors in the vehicle to recognize an
excessively swaying trailer and will take the appropriate
actions to attempt to stop the sway. TSC will become
active automatically once an excessively swaying trailer is
recognized.
NOTE:TSC cannot stop all trailers from swaying. Always use
caution when towing a trailer and follow the trailer tongue
weight recommendations
Úpage 178.
When TSC is functioning, the ESC Activation/Malfunction
Indicator Light will flash, the engine power may be reduced
and you may feel the brakes being applied to individual
wheels to attempt to stop the trailer from swaying. TSC is
disabled when the ESC system is in the “Partial Off” mode.
AUXILIARY DRIVING SYSTEMS
BLIND SPOT MONITORING (BSM)
BSM system uses two radar sensors, located inside the
rear fascia/bumper, to detect highway licensable vehicles
(automobiles, trucks, motorcycles, etc.) that enter the
blind spot zones from the rear/front/side of the vehicle.

Rear Detection Zones

When the vehicle is started, the BSM Warning Light will
momentarily illuminate in both outside rearview mirrors to
let the driver know that the system is operational. The
BSM system sensors operate when the vehicle is in any
forward gear.
The BSM detection zone covers approximately one lane in
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the side of the vehicle, near the B-pillar,
and extends approximately 10 ft (3 m) beyond the rear
fascia/bumper of the vehicle. The BSM system monitors
the detection zones on both sides of the vehicle when the
vehicle speed is 7 mph (11 km/h) or higher and will alert
the driver of vehicles in these areas. BSM will alert earlier
on faster-approaching vehicles – up to 33 mph (54 km/h)
difference.
NOTE:The BSM system detection zone DOES NOT change if your
vehicle is towing a trailer. Therefore, visually verify the
adjacent lane is clear for both your vehicle and trailer
before making a lane change. If the trailer or other object
(i.e., bicycle, sports equipment) extends beyond the side of your vehicle, this may result in random false detections
on the trailer, and false chimes when the turn signal is
used
Úpage 197.
The BSM system can become blocked if snow, ice, mud, or
other road contaminations accumulate on the rear fascia/
bumper where the radar sensors are located. The system
may also detect blockage if the vehicle is operated in
areas with extremely low radar returns such as a desert or
parallel to a large elevation drop. If blockage is detected,
a “Blind Spot Temporarily Unavailable, Sensor Blocked”
message will display in the cluster, both mirror lights will
illuminate, and BSM and RCP alerts will not occur. This is
normal operation. The system will automatically recover
and resume function when the condition clears or when
an ignition cycle occurs. To minimize system blockage, do
not block the area of the rear fascia/ bumper where the
radar sensors are located with foreign objects (bumper
stickers, bicycle racks, etc.) and keep it clear of road
contaminations.

Sensor Location (Left Side Shown)

WARNING!
If TSC activates while driving, slow the vehicle down,
stop at the nearest safe location, and adjust the trailer
load to eliminate trailer sway.

23_WS_OM_EN_USC_t.book Page 247

250SAFETY
Blind Spot Alert Lights/Chime
When operating in Blind Spot Alert Lights/Chime mode,
the BSM system will provide a visual alert in the
appropriate side view mirror based on a detected object.
If the turn signal is then activated, and it corresponds to
an alert present on that side of the vehicle, an audible
chime will also be sounded. Whenever a turn signal and
detected object are present on the same side at the same
time, both the visual and audible alerts will be issued. In
addition to the audible alert the radio (if on) will also be
muted.
NOTE:Whenever an audible alert is requested by the BSM
system, the radio is also muted.
When the system is in RCP, the system shall respond with
both visual and audible alerts when a detected object is
present. Whenever an audible alert is requested, the radio
is also muted. Turn/hazard signal status is ignored; the
RCP state always requests the chime.
Blind Spot Alert Off
When the BSM system is turned off, there will be no visual
or audible alerts from either the BSM or RCP systems.
NOTE:The BSM system will store the current operating mode
when the vehicle is shut off. Each time the vehicle is
started, the previously stored mode will be recalled and
used.
FORWARD COLLISION WARNING (FCW)
W
ITH MITIGATION
FCW with Mitigation system provides the driver with
audible warnings, visual warnings (within the instrument
cluster display), and may apply a brake jerk to warn the
driver when it detects a potential frontal collision. The
warnings and limited braking are intended to provide the
driver with enough time to react, avoid or mitigate the
potential collision.
NOTE:FCW monitors the information from the forward looking
sensors as well as the Electronic Brake Controller (EBC), to
calculate the probability of a forward collision. When the
system determines that a forward collision is probable, the
driver will be provided with audible and visual warnings
and may provide a brake jerk warning. If the driver does
not take action based upon these progressive warnings,
then the system will provide a limited level of active
braking to help slow the vehicle and mitigate the potential
forward collision. If the driver reacts to the warnings by
braking and the system determines that the driver intends
to avoid the collision by braking but has not applied suffi -
cient brake force, the system will compensate and provide
additional brake force as required.
If a Forward Collision Warning with Mitigation event begins
at a speed below 39 mph (62 km/h), the system may provide the maximum or partial braking to mitigate the
potential forward collision. If the Forward Collision
Warning with Mitigation event stops the vehicle
completely, the system will hold the vehicle at a standstill
for two seconds and then release the brakes.
FCW Message

When the system determines a collision with the vehicle in
front of you is no longer probable, the warning message
will be deactivated.
NOTE:
 The minimum speed for FCW activation is 3 mph
(5 km/h).
 The FCW alerts may be triggered on objects other than
vehicles, such as guardrails or sign posts based on the
course prediction. This is expected and is a part of
normal FCW activation and functionality.
 It is unsafe to test the FCW system. To prevent such
misuse of the system, after four Active Braking events
within an ignition cycle, the Active Braking portion of
FCW will be deactivated until the next ignition cycle.
 The FCW system is intended for on-road use only. If the
vehicle is taken off-road, the FCW system should be
deactivated to prevent unnecessary warnings to the
surroundings. If the vehicle enters 4WD Low, the FCW
system will be automatically deactivated.
