Electronic Stability Control (ESC)
The Electronic Stability Control (ESC)
system 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 oversteer or understeer
condition. Engine power may also be
reduced to help the vehicle maintain the
desired path.
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.
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.
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 TCS is active. If the “ESC Activa
-
tion/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!
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 acci -
dents, including those resulting from
excessive speed in turns, driving on very
slippery surfaces, or hydroplaning. ESC
also cannot prevent accidents resulting
from loss of vehicle control due to inap -
propriate driver input for the conditions.
Only a safe, attentive, and skillful driver
can prevent accidents. The capabilities
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 prop -
erly maintain your vehicle, may change
the handling characteristics of your
vehicle, and may negatively affect the
performance of the ESC system.
Changes to the steering system, suspen -
sion, 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 modifica-
tion 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.

Traction Control System (TCS)
The Traction Control System (TCS) monitors
the amount of wheel spin of each of the
driven wheels. If wheel spin is detected, the
TCS may apply brake pressure to the spin-
ning wheel(s) and/or reduce engine power to
provide enhanced acceleration and stability.
A feature of the TCS, Brake Limited Differen -
tial (BLD), functions similar to a limited slip
differential and controls the wheel spin
across a driven axle. If one wheel on a driven
axle is spinning faster than the other, the
system will apply the brake of the spinning
wheel. This will allow more engine torque to
be applied to the wheel that is not spinning.
BLD may remain enabled even if TCS and
Electronic Stability Control (ESC) are in a
reduced mode.
Trailer Sway Control (TSC)
Trailer Sway Control (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 exces -
sively 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 recommen
-
dations. Refer to “Trailer Towing” in
“Starting And Operating” for further informa -
tion.
When TSC is functioning, the “ESC Activa -
tion/Malfunction Indicator Light” will flash,
the engine power may be reduced and you
may feel the brakes being applied to indi -
vidual wheels to attempt to stop the trailer
from swaying. TSC is disabled when the ESC
system is in the “Partial Off” or “Full Off”
modes.
AUXILIARY DRIVING
SYSTEMS
Blind Spot Monitoring (BSM) — If
Equipped
The Blind Spot Monitoring (BSM) system
uses two radar-based sensors, located inside
the rear bumper fascia, 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 rear view mirrors to let the
driver know that the system is operational.
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.

Modes Of Operation
Three selectable modes of operation are
available in the Uconnect System. Refer to
“Uconnect Settings” in “Multimedia” in the
Owner’s Manual for further information.
Blind Spot Alert Lights Only
When operating in Blind Spot Alert mode,
the BSM system will provide a visual alert in
the appropriate side view mirror based on a
detected object. However, when the system
is operating in Rear Cross Path (RCP) mode,
the system will respond with both visual and
audible alerts when a detected object is
present. Whenever an audible alert is
requested, the radio is muted.
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 objectare 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 oper
-
ating mode when the vehicle is shut off.
Each time the vehicle is started the previ -
ously stored mode will be recalled and used.
Forward Collision Warning (FCW) With
Mitigation — If Equipped
FCW With Mitigation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with
audible warnings, visual warnings (within the
instrument cluster display), and may apply a
haptic warning to warn the driver when it
detects a potential frontal collision. The
warnings 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 Elec -
tronic Brake Controller (EBC), to calculate
the probability of a forward collision. When
the system determines that a forward colli -
sion is probable, the driver will be provided
with audible and visual warnings and may
provide a haptic warning in the form of a
brake jerk.
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

To Deactivate
A soft tap on the brake pedal, pushing the
CANC (cancel) button, or normal brake pres-
sure while slowing the vehicle will deactivate
the speed control without erasing the set
speed from memory.
Pushing the on/off button or placing the igni -
tion in the OFF position, erases the set speed
from memory.
ADAPTIVE CRUISE
CONTROL (ACC) — IF
EQUIPPED
If your vehicle is equipped with Adaptive
Cruise Control (ACC), the controls operate
exactly the same as the Speed Control with
only a couple of differences. With this
option, you can set a specified distance you
would like to maintain between you and the
vehicle in front of you. Adaptive Cruise Switches
NOTE:
If the sensor does not detect a vehicle
ahead of you, ACC will maintain a fixed set
speed.
If the ACC sensor detects a vehicle ahead,
ACC will apply limited braking or acceler -
ation (not to exceed the original set speed) automatically to maintain a preset
following distance, while matching the
speed of the vehicle ahead.

1 — Normal (Fixed Speed) Cruise Control On/Off

2 — SET (+)/Accel
3 — RES/Resume
4 — SET (-)/Decel
5 — Distance Setting Increase
6 — Adaptive Cruise Control (ACC) On/Off
7 — Distance Setting Decrease
8 — CANC/Cancel
WARNING!
Adaptive Cruise Control (ACC) is a conve-
nience system. It is not a substitute for
active driving involvement. It is always
the driver’s responsibility to be attentive
of road, traffic, and weather conditions,
vehicle speed, distance to the vehicle
ahead; 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 and
death or serious personal injury.
The ACC system:
Does not react to pedestrians, oncoming vehicles, and stationary
objects (e.g., a stopped vehicle in a
traffic jam or a disabled vehicle).
Cannot take street, traffic, and weather conditions into account, and
may be limited upon adverse sight
distance conditions.

(resume) button, or apply the accelerator
pedal to reengage the ACC to the existing
set speed.
The ACC system maintains set speed when
driving uphill and downhill. However, a
slight speed change on moderate hills is
normal. In addition, downshifting may
occur while climbing uphill or descending
downhill. This is normal operation and
necessary to maintain set speed. When
driving uphill and downhill, the ACC
system will cancel if the braking tempera-
ture exceeds normal range (overheated).
Setting The Following Distance In ACC
The specified following distance for ACC can
be set by varying the distance setting
between four bars (longest), three bars
(long), two bars (medium) and one bar
(short). Using this distance setting and the
vehicle speed, ACC calculates and sets the
distance to the vehicle ahead. This distance
setting appears in the instrument cluster
display.

To increase the distance setting, push the
Distance Setting — Increase button and
release. Each time the button is pushed, the
distance setting increases by one bar (longer).
To decrease the distance setting, push the
Distance Setting — Decrease button and
release. Each time the button is pushed, the
distance setting decreases by one bar
(shorter).
PARKSENSE REAR PARK
ASSIST — IF EQUIPPED
The ParkSense Rear Park Assist system
provides visual and audible indications of
the distance between the rear fascia and a
detected obstacle when backing up (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. Refer to “Ucon
-
nect Settings” in “Multimedia” in the
Owner’s Manual for information on turning
Rear Braking Assist on or off.
Refer to “ParkSense System Usage Precau -
tions” in this section for limitations of this
system and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
ParkSense Sensors
The four ParkSense sensors, located in the
rear fascia/bumper, monitor the area behind
the vehicle that is within the sensors’ field of
view. The sensors can detect obstacles from
approximately 12 inches (30 cm) up to
79 inches (200 cm) from the rear fascia/
bumper in the horizontal direction,
depending on the location, type and orienta -
tion of the obstacle.
ParkSense Warning Display
The ParkSense Warning screen will only be
displayed if Sound and Display is selected
from the Customer - Programmable Features
section of the Uconnect System.
Refer to "Uconnect Settings” in “Multi -
media” in the Owner’s Manual for further
information.
The ParkSense Warning screen is located
within the instrument cluster display. It
provides visual warnings to indicate the
distance between the rear fascia/bumper and
the detected obstacle.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
the Owner’s Manual for further information.

PARKSENSE FRONT AND
REAR PARK ASSIST — IF
EQUIPPED
The ParkSense Park Assist system provides
visual and audible indications of the
distance between the rear and/or front fascia
and a detected obstacle when backing up or
moving forward (e.g. during a parking
maneuver). The vehicle brakes may be auto-
matically applied and released when
performing a reverse parking maneuver if the
system detects a possible collision with an
obstacle.
Refer to “ParkSense System Usage Precau -
tions” in “Starting And Operating” in the
Owner’s Manual for limitations of this system
and recommendations.
ParkSense will retain the last system state
(enabled or disabled) from the last ignition
cycle when the ignition is changed to the ON/
RUN position.
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 atten -
tion 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 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 ParkSense 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 ParkSense.

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-auto-
matic” 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).
NOTE:
The driver is always responsible for
controlling the vehicle, responsible for any
surrounding objects, and must intervene
as required.
The system is provided 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 dealer 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
performance 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.
The ParkSense Active Park Assist system can
be enabled and disabled with the ParkSense
Active Park Assist switch, located on the
switch panel below the Uconnect display. To enable the ParkSense Active
Park Assist system, push the Park
-
Sense Active Park Assist switch
once (LED turns on).
To disable the ParkSense Active Park Assist
system, push the ParkSense Active Park
Assist switch again (LED turns off).
Refer to the Owner’s Manual for further infor -
mation.LANESENSE — IF EQUIPPED
LaneSense Operation
The LaneSense system is operational at
speeds above 37 mph (60 km/h) and below
112 mph (180 km/h). The LaneSense
system uses a forward looking camera to
detect lane markings and measure vehicle
position within the lane boundaries.

When both lane markings are detected and the
driver unintentionally drifts out of the lane (no
turn signal applied), the LaneSense system
provides a haptic warning in the form of torque
applied to the steering wheel, as well as a
visual warning in the instrument cluster
display, to prompt the driver to remain within
the lane boundaries. The LaneSense system
