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
Activation/Malfunction Indicator Light” be-
gins 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) can-
not prevent the natural laws of physics
from acting on the vehicle, nor can it
increase the traction afforded by prevail-
ing road conditions. ESC cannot prevent
accidents, including those resulting
from excessive speed in turns, driving on
very slippery surfaces, or hydroplaning.
ESC also cannot prevent accidents re-
sulting from loss of vehicle control due
to inappropriate driver input for the con-
ditions. Only a safe, attentive, and skill-
ful driver can prevent accidents. The
capabilities of an ESC equipped vehicle
must never be exploited in a reckless or
dangerous manner which could jeopar-
dize 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 ve-
hicle, and may negatively affect the per-
formance of the ESC system. Changes to
the steering system, suspension, brak-
WARNING!
ing system, tire type and size or wheel
size may adversely affect ESC perfor-
mance. Improperly inflated and un-
evenly worn tires may also degrade ESC
performance. Any vehicle modification
or poor vehicle maintenance that re-
duces the effectiveness of the ESC sys-
tem can increase the risk of loss of
vehicle control, vehicle rollover, per-
sonal injury and death.
ESC Operating Modes
NOTE:
Depending upon model and mode of opera-
tion, the ESC system may have multiple op-
erating 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

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 anytime the ESC is in “Full
Off” mode (if equipped). Refer to “Electronic
Stability Control (ESC)” in this section for a
complete explanation of the available ESC
modes.
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 roll overs, 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.
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 recog-
nized.
NOTE:
TSC cannot stop all trailers from swaying.
Always use caution when towing a trailer and
follow the trailer tongue weight recommenda-
tions. Refer to “Trailer Towing” in “Starting
And Operating” for further information.
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” or “Full
Off” modes.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.
Ready Alert Braking (RAB)
Ready Alert Braking may reduce the time
required to reach full braking during emer-
gency braking situations. It anticipates when
an emergency braking situation may occur by
monitoring how fast the throttle is released by
the driver. The EBC will prepare the brake
system for a panic stop.
Rain Brake Support (RBS)
Rain Brake Support may improve braking
performance in wet conditions. It will periodi-
cally apply a small amount of brake pressure
to remove any water buildup on the front
brake rotors. It functions when the wind-
shield wipers are in LO or HI speed. When
Rain Brake Support is active, there is no
notification to the driver and no driver inter-
action is required.
SAFETY
84

• Vehicle is shifted to PARK.
Disabling SSC
SSC will deactivate and be disabled if any of
the following conditions occur:
• The driver pushes the SSC switch.
• The driveline is shifted out of 4WD Low
Range.
• The parking brake is applied.
• Driver door opens.
• The vehicle is driven greater than 20 mph
(32 km/h) for greater than 70 seconds.
• The vehicle is driven greater than 40 mph
(64 km/h) (SSC exits immediately).
Feedback To The Driver:
The instrument cluster has an SSC icon and
the SSC switch has an LED which offer feed-
back to the driver about the state SSC is in.
• The cluster icon and switch lamp will illu-
minate and remain on solid when SSC is
enabled or activated. This is the normal
operating condition for SSC.• The cluster icon and switch lamp will flash
for several seconds then extinguish when
the driver pushes the SSC switch but en-
able conditions are not met.
• The cluster icon and switch lamp will flash
for several seconds then extinguish when
SSC disables due to excess speed.
• The cluster icon and switch lamp will flash
then extinguish when SSC deactivates due
to overheated brakes.
WARNING!
SSC is only intended to assist the driver in
controlling vehicle speed when driving in
off road conditions. The driver must re-
main attentive to the driving conditions
and is responsible for maintaining a safe
vehicle speed.
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, mo-
torcycles, etc.) that enter the blind spot
zones from the rear/front/side of the vehicle.
When the vehicle is started, the BSM warning
light will momentarily illuminate in both out-
side rear view mirrors to let the driver know
Rear Detection Zones
SAFETY

WARNING!
other vehicles, obstructions, and blind
spots before backing up. Failure to do so
can result in serious injury or death.
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 de-
tected 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 pres-
ent. 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 mirrorbased 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. When-
ever 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 oper-
ating 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) With
Mitigation — If Equipped
Forward Collision Warning (FCW) With Miti-
gation Operation
The Forward Collision Warning (FCW) system
with mitigation provides the driver with au-
dible 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 for-
ward looking sensors as well as the Electronic
Brake Controller (EBC), to calculate the prob-
ability of a forward collision. When the sys-

To Set A Desired Speed
Turn the Speed Control on.
NOTE:
The vehicle should be traveling at a steady
speed and on level ground before pushing the
SET (+) or SET (-) button.
When the vehicle has reached the desired
speed, push the SET (+) or SET (-) button and
release. Release the accelerator and the ve-
hicle will operate at the selected speed.
To Resume Speed
To resume a previously set speed, push the
RES button and release. Resume can be used
at any speed above 20 mph (32 km/h).
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 cycling the igni-
tion to OFF, erases the set speed from
memory.
ADAPTIVE CRUISE
CONTROL (ACC) — IF
EQUIPPED
If your vehicle is equipped with Adaptive
Cruise Control, 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.
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 accelera-
tion (not to exceed the original set speed)
automatically to maintain a preset follow-
ing distance, while matching the speed of
the vehicle ahead.
WARNING!
• Adaptive Cruise Control (ACC) is a con-
venience system. It is not a substitute
for active driving involvement. It is al-
ways the driver’s responsibility to be at-
tentive of road, traffic, and weather con-
ditions, 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 re-
quired 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, on-
coming vehicles, and stationary ob-

jects (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.
• Does not always fully recognize
complex driving conditions, which
can result in wrong or missing dis-
tance warnings.
• Will bring the vehicle to a complete
stop while following a target vehicle
and hold the vehicle for approxi-
mately 3 minutes in the stop posi-
tion. If the target vehicle does not
start moving within 3 minutes the
parking brake will be activated, and
the ACC system will be cancelled.
You should switch off the ACC system:
• When driving in fog, heavy rain, heavy
snow, sleet, heavy traffic, and complex
driving situations (i.e., in highway con-
struction zones).
WARNING!
• When entering a turn lane or highway off
ramp; when driving on roads that are
winding, icy, snow-covered, slippery, or
have steep uphill or downhill slopes.
• When towing a trailer up or down steep
slopes.
• When circumstances do not allow safe
driving at a constant speed.
Activating Adaptive Cruise Control (ACC )
Push and release the Adaptive Cruise Control
(ACC) on/off button.
The minimum set speed for the ACC system is
19 mph (30 km/h).
When the system is turned on and in the
ready state, the instrument cluster display
will read “ACC Ready.”
When the system is off, the instrument clus-
ter display will read “Adaptive Cruise Control
(ACC) Off.”

Setting The Following Distance In ACC
The specified following distance for ACC can
be set by varying the distance setting be-
tween 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 re-
lease. 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 pro-
vides visual and audible indications of the
distance between the rear fascia and a de-
tected obstacle when backing up, e.g. duringa parking maneuver. If your vehicle is
equipped with an automatic transmission,
the vehicle brakes may be automatically ap-
plied 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” for limitations of this system and rec-
ommendations.
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, depend-
ing on the location, type and orientation 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 “Multime-
dia” in your Owner’s Manual for further infor-
mation.
The ParkSense Warning screen is located
within the instrument cluster display. It pro-
vides visual warnings to indicate the distance
between the rear fascia/bumper and the de-
tected obstacle.
Refer to “Instrument Cluster Display” in
“Getting To Know Your Instrument Panel” in
your Owner’s Manual for further information.
Enabling And Disabling ParkSense
ParkSense can be enabled and disabled with
the ParkSense switch.
When the ParkSense switch is
pushed to disable the system, the
instrument cluster will display the
“PARKSENSE OFF” message for
approximately five seconds. When the gear
