208 SAFETY
Feedback To The Driver
The instrument cluster has an HDC icon and the HDC switch
has an LED icon, which offers feedback to the driver about
the state HDC is in.
• The cluster icon and switch lamp will illuminate andremain on solid when HDC is enabled or activated. This is
the normal operating condition for HDC.
• The cluster icon and switch lamp will flash for several seconds then extinguish when the driver pushes the HDC
switch but enable conditions are not met.
• The cluster icon and switch lamp will flash for several seconds then extinguish when HDC disables due to excess
speed.
• The cluster icon and switch lamp will flash when HDC deactivates due to overheated brakes. The flashing will
stop and HDC will activate again once the brakes have
cooled sufficiently.AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses two
radar-based sensors, located inside the taillights, to detect
highway licensable vehicles (automobiles, trucks, motorcy -
cles, etc.) that enter the blind spot zones from the rear/front/
side of the vehicle.
Rear Detection Zones
WARNING!
HDC is only intended to assist the driver in controlling
vehicle speed when descending hills. The driver must
remain attentive to the driving conditions and is
responsible for maintaining a safe vehicle speed.

SAFETY 209
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 or REVERSE and enters stand-by mode when the
vehicle is in PARK.
The BSM detection zone covers approximately one lane
width on both sides of the vehicle 12 ft (3.8 m). The zone
length starts at the outside rear view mirror and extends
approximately 10 ft (3 m) beyond the rear bumper of the
vehicle. The BSM system monitors the detection zones on
both sides of the vehicle when the vehicle speed reaches
approximately 6 mph (10 km/h) or higher and will alert the
driver of vehicles in these areas.
NOTE:
• The BSM system DOES NOT alert the driver about rapidlyapproaching vehicles that are outside the detection zones.
• The Blind Spot Monitoring (BSM) system may experience drop outs (blinking on and off) of the side mirror Warning
Indicator lamps when a motorcycle or any small object
remains at the side of the vehicle for extended periods of
time (more than a couple of seconds). The vehicle’s taillights, where the radar sensors are located,
must remain free of snow, ice, and dirt/road contamination
so that the BSM system can function properly. Do not block
the taillights with foreign objects (bumper stickers, bicycle
racks, etc.).
Radar Sensor Locations
If the system detects degraded performance due to contami -
nation or foreign objects, a message will warn you of a
blocked sensor and the warning indicators in side view
mirrors will be on. The warning indicators will remain illu-
minated until blockage clearing conditions are met. First

clear the taillights around the sensors of the blockage. After
removing the blockage, the following procedure can be used
to reset the system:
• Cycle the ignition from ON to OFF and then back ON.
If the blockage message is still present after cycling the igni-
tion and driving in traffic, check again for a blockage.
The BSM system notifies the driver of objects in the detection
zones by illuminating the BSM warning light located in the
outside mirrors in addition to sounding an audible (chime)
alert and reducing the radio volume. Refer to “Modes Of
Operation” in this section for further information.
Warning Light Location The BSM system monitors the detection zone from three
different entry points (side, rear, front) while driving to see
if an alert is necessary. The BSM system will issue an alert
during these types of zone entries.
Entering From The Side
Vehicles that move into your adjacent lanes from either side
of the vehicle.
Side Monitoring

SAFETY 211
Entering From The Rear
Vehicles that come up from behind your vehicle on either
side and enter the rear detection zone with a relative speed
of less than 30 mph (48 km/h).Rear Monitoring Overtaking Traffic
If you pass another vehicle slowly with a relative speed less
than 15 mph (24 km/h) and the vehicle remains in the blind
spot for approximately 1.5 seconds, the warning light will be
illuminated. If the difference in speed between the two vehi
-
cles is greater than 15 mph (24 km/h), the warning light will
not illuminate.
Overtaking/Approaching
4

SAFETY 213
The BSM system will not alert you of objects that are trav-
eling in the opposite direction of the vehicle in adjacent
lanes.
Opposing Traffic Rear Cross Path (RCP)
The Rear Cross Path (RCP) feature is intended to aid the
driver when backing out of parking spaces where their
vision of oncoming vehicles may be blocked. Proceed slowly
and cautiously out of the parking space until the rear end of
the vehicle is exposed. The RCP system will then have a clear
view of the cross traffic and if an oncoming vehicle is
detected, alert the driver.
RCP Detection Zones
RCP monitors the rear detection zones on both sides of the
vehicle, for objects that are moving toward the side of the
vehicle with a minimum speed of approximately 3 mph
WARNING!

The Blind Spot Monitoring system is only an aid to help detect
objects in the blind spot zones. The BSM system is not
designed to detect pedestrians, bicyclists, or animals. Even if
your vehicle is equipped with the BSM system, always check
your vehicle’s mirrors, glance over your shoulder, and use your
turn signal before changing lanes. Failure to do so can result in
serious injury or death.

214 SAFETY
(5 km/h), to objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situations.
NOTE:
In a parking lot situation, oncoming vehicles can be obscured
by vehicles parked on either side. If the sensors are blocked
by other structures or vehicles, the system will not be able to
alert the driver.
When RCP is on and the vehicle is in REVERSE, the driver is
alerted using both the visual and audible alarms, including
reducing the radio volume.Modes Of Operation
Three selectable modes of operation are available in the
Uconnect System.
Refer to “Uconnect Settings” in “Multimedia” 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 object are
WARNING!
Rear Cross Path Detection (RCP) is not a back up aid
system. It is intended to be used to help a driver detect
an oncoming vehicle in a parking lot situation. Drivers
must be careful when backing up, even when using RCP.
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. Failure to do so can result in serious
injury or death.

216 SAFETY
Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (FCW) system provides the
driver with audible, visual warnings (within the instrument
cluster display), and may apply a haptic warning in the form
of a brake jerk, 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 Electronic Brake Controller (EBC), to calcu-
late 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 as well as
a possible haptic warning in the form of a brake jerk.
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 warn -
ings by braking and the system determines 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 FCW with Mitigation event begins at a speed below
32 mph (52 km/h), the system may provide the maximum
braking possible 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 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.

SAFETY 217
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 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 a
key cycle, the Active Braking portion of FCW will be deac -
tivated until the next key cycle.
• The FCW system is intended for on-road use only. If the vehicle is taken off-road, the FCW system should be deac -
tivated to prevent unnecessary warnings to the surround -
ings.
• 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. Turning FCW On or Off
The FCW button is located in the Uconnect display in the
control settings. Refer to “Uconnect Settings” in “Multi
-
media” in the Owner's Manual for further information.
• To turn the FCW system on, press the forward collision button once to turn the system on.
• To turn the FCW system off, press the forward collision button once to turn the system off.
NOTE:
• When the FCW is “on”, this allows the system to warn the driver of a possible collision with the vehicle in front.
• When the FCW is “off” prevents the system from warning the driver of a possible collision with the vehicle in front.
If the FCW is set to “off”, “FCW OFF" will be displayed in
the instrument cluster display.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.
4

218 SAFETY
• When FCW status is set to “Only Warning” prevents thesystem from providing limited active braking, or addi -
tional brake support if the driver is not braking adequately
in the event of a potential frontal collision.
• When FCW status is set to “Warning and Braking” this allows the system to warn the driver of a possible collision
with the vehicle in front using audible/visual warnings
and it applies autonomous braking.
• The system will retain the last setting selected by the driver after ignition shutdown.
FCW Braking Status And Sensitivity
The FCW sensitivity and Active Braking status are program -
mable through the Uconnect System. Refer to “Uconnect
Settings” in “Multimedia” in the Owner's Manual for further
information.
• Far
•When the sensitivity of FCW is set to the “Far” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible more
distant collisions with the vehicle in front using
audible/visual warnings. • More cautious drivers that do not mind frequent warn
-
ings may prefer this setting.
• Medium •When the sensitivity of FCW is set to the “Medium”setting and the system status is “Warning and
Braking”, this allows the system to warn the driver of a
possible collision with the vehicle in front using
audible/visual warnings.
• Near •When the sensitivity of FCW is set to the “Near” settingand the system status is “Warning and Braking”, this
allows the system to warn the driver of a possible closer
collisions with the vehicle in front using audible/visual
warnings.
•This setting provides less reaction time than the “Far” and “Medium” settings, which allows for a more
dynamic driving experience.
•More dynamic or aggressive drivers that want to avoid frequent warnings may prefer this setting.

SAFETY 219
FCW Limited Warning
If the instrument cluster displays “ACC/FCW Limited Func-
tionality” or “ACC/FCW Limited Functionality Clean Front
Windshield” momentarily, there may be a condition that
limits FCW functionality. Although the vehicle is still driv -
able under normal conditions, the active braking may not be
fully available. Once the condition that limited the system
performance is no longer present, the system will return to
its full performance state. If the problem persists, see an
authorized dealer.
Service FCW Warning
If the system turns off, and the instrument cluster 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. General Information
