FORWARD COLLISION WARNING (FCW) WITH
MITIGATION — IF EQUIPPED
Forward Collision Warning (FCW) With Mitigation
Operation
The Forward Collision Warning (FCW) system with
mitigation provides the driver with audible warnings,
visual warnings (within the DID), 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 progres-
sive 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 deter-
mines that the driver intends to avoid the collision by
braking but has not applied sufficient 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 26 mph (42 km/h), the system
may provide the maximum or partial braking to mitigate
the potential forward collision. If the Forward Collision
3

Warning with Mitigation event stops the vehicle com-
pletely, the system will hold the vehicle at a standstill for
two seconds and then release the brakes.
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 1 mph
(2 km/h).
• The FCW alerts may be triggered on objects other than
vehicles such as guard rails 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 Range,
the FCW system will be automatically deactivated.
FCW Message
220 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

WARNING!
Forward Collision Warning (FCW) is not intended to
avoid a collision on its own, nor can FCW detect
every type of potential collision. The driver has the
responsibility to avoid a collision by controlling the
vehicle via braking and steering. Failure to follow
this warning could lead to serious injury or death.
Turning FCW ON Or OFF
NOTE:The default status of FCW is “On”, this allows
the system to warn you of a possible collision with the
vehicle in front of you.
The forward collision button is located in the Uconnect
display in the controls settings.
To turn the FCW system OFF, press the forward collision
button once to turn the system OFF. To turn the FCW system back ON, press the forward
collision button again to turn the system ON.
Changing the FCW status to “OFF” prevents the system
from warning you of a possible collision with the vehicle
in front of you.
NOTE:
The FCW system state is kept in memory from
one ignition cycle to the next. If the system is turned OFF,
it will remain off when the vehicle is restarted.
Changing FCW And Active Braking Status
The FCW Sensitivity And Active Braking Settings are
programmable through the Uconnect System. Refer to
“Uconnect Settings” in “Understanding Your Instrument
Panel” for further information.
The default status of FCW is the “Medium” setting and
the Active Braking is in the “On” setting. This allows the
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 221

system to warn the driver of a possible collision with the
vehicle in front using audible/visual warnings and it
applies autonomous braking.
Changing the FCW status to “Far” setting allows the
system to warn the driver of a possible collision with the
vehicle in front using audible/visual warning when the
latter is at a farther distance thanMediumsetting. This
provides the most reaction time to avoid a possible
collision.
Changing the FCW status to the “Near” setting, allows
the system to warn the driver of a possible collision with
the vehicle in front when the distance between the
vehicle in the front is much closer. This setting provides
less reaction time than the “Far” and “Medium” settings,
which allows for a more dynamic driving experience. Changing the Active Braking status to “Off” prevents the
system from providing autonomous braking, or addi-
tional brake support if the driver is not braking ad-
equately in the event of a potential frontal collision.
NOTE:
•
The system will retain the last setting selected by the
driver after ignition shut down.
• FCW may not react to irrelevant objects such as
overhead objects, ground reflections, objects not in the
path of the vehicle, stationary objects that are far away,
oncoming traffic, or leading vehicles with the same or
higher rate of speed.
• FCW will be disabled like ACC, with the unavailable
screens.

FCW Limited Warning
If the DID displays “ACC/FCW Limited Functionality”
or “ACC/FCW Limited Functionality Clean Front Wind-
shield” momentarily, there may be a condition that limits
FCW functionality. Although the vehicle is still drivable
under normal conditions, the active braking may not be
fully available. Once the condition that limited the sys-
tem performance is no longer present, the system will
return to its full performance state. If the problem per-
sists, see your authorized dealer.
Service FCW Warning
If the system turns off, and the DID displays:
•ACC/FCW Unavailable Service Required
• Cruise/FCW Unavailable Service Required
This indicates there is an internal system fault. Although
the vehicle is still drivable under normal conditions, have
the system checked by an authorized dealer.
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. If your vehicle is equipped
with an Automatic Transmission, 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 override the automatic braking func-
tion by pressing the gas pedal, turning ParkSense off
via ParkSense switch, or changing the gear while the
automatic brakes are being applied.
• Automatic brakes will not be available if ESC is not
available.
3
UNDERSTANDING THE FEATURES OF YOUR VEHICLE 223

•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 collid-
ing 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-Programmable Features
section of the Uconnect System.
• ParkSense will retain its last known configuration 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 ob-
stacles when backing up in REVERSE gear.
NOTE:
•
The driver is always responsible for controlling the
vehicle.
• The system is provided 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.
Refer to ParkSense System Usage Precautions for limita-
tions 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.
224 UNDERSTANDING THE FEATURES OF YOUR VEHICLE

ParkSense can be active only when the gear selector is in
REVERSE. If ParkSense is enabled at this gear selector
position, the system will remain active until the vehicle
speed is increased to approximately 7 mph (11 km/h) or
above. When in REVERSE and above the system’s oper-
ating speed, a warning will appear within the Driver
Information Display (DID) indicating the vehicle speed is
too fast. The system will become active again if the
vehicle speed is decreased to speeds less than approxi-
mately 6 mph (9 km/h).
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 in (30 cm) up to 79 in
(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 toUconnect Settings” in “Understanding Your
Instrument Panel” for further information.
The ParkSense Warning screen is located within the DID.
It provides visual warnings to indicate the distance
between the rear fascia/bumper and the detected ob-
stacle. Refer to “Driver Information Display (DID)” for
further information.

ParkSense Display
When the vehicle is in REVERSE and an obstacle has
been detected, the warning display will turn ON indicat-
ing the system status.The system will indicate a detected obstacle by showing
a single arc in the left and/or right rear regions based on
the obstacle’s distance and location relative to the vehicle.
If an obstacle is detected in the left and/or right rear
region, the display will show a single arc in the left
and/or right rear region and the system will produce a
tone. As the vehicle moves closer to the obstacle, the
display will show the single arc moving closer to the
vehicle and the tone will change from a single 1/2 second
tone to slow, to fast, to continuous.
