216 SAFETY
For information on how Blind Spot Monitoring functions
when pulling a trailer, refer to “Trailer Merge Assist” in this
section.
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
(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.
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.

SAFETY 217
When RCP is on and the vehicle is in REVERSE (R), 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 viewmirror 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
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.
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.

218 SAFETY
Blind Spot Alert Off
When the BSM system is turned off there will be no visual or
audible alerts from either the BSM, RCP, or Trailer Merge
Assist 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.
Trailer Merge Assist
NOTE:
When Trailer Merge Assist is activated, Rear Cross Path is
disabled.
Trailer Merge Assist is a function of the Blind Spot Moni-
toring (BSM) system that extends the blind spot zone to work
while pulling a trailer. Trailer Merge Assist consists of three
sub functions:
• Automatic Trailer Detection
• Trailer Length Detection
• Trailer Merge Warning Blind Spot Zones With Trailer Merge Assist
Automatic Trailer Detection
There are two modes of operation for the detection of the
trailer length:
• Automatic Mode — When “Auto Mode” is selected, the
system will use the blind spot sensors to automatically
determine the presence and length of a trailer. The pres -
ence of a trailer will be detected using the blind spot radar
within 90 seconds of forward movement of the vehicle.
1 — Vehicle
2 — Trailer
2020_DT_1500_OM_US.book Page 218

SAFETY 219
The vehicle must be moving above 6 mph (10 km/h) to
activate the feature. Once the trailer has been detected, the
system will default to the maximum blind spot zone until
the length has been verified. You will see “Auto” in the
instrument panel cluster .
• Max Mode — When “Max Mode” is selected, the system
will default to the maximum blind spot zone regardless of
what size trailer is attached
NOTE:
Selected setting is stored when the ignition is cycled OFF. To
change this setting, it must be selected through the Uconnect
Settings. Refer to “Uconnect Settings” in “Multimedia” for
further information.
Trailer Length Detection
Once the trailer presence has been established. The trailer
length will be established (by making a 90 degree turn) and
then the trailer length category (example 10-20 ft (3 m to
6 m)) will be displayed. This can take up to 30 seconds after
completing the turn. NOTE:
During the same ignition cycle, if the vehicle is at a standstill
for a minimum of 90 seconds, a new “trailer detection
request” is enabled by the system once the vehicle resumes
motion.
Maximum length supported by the Trailer Merge Assist
feature is 39.5 ft (12 m). Trailer length is considered the
forward most portion of the trailer hitch to the rearward
most portion of the body, bumper, or ramp of the trailer.
Maximum width supported by the Trailer Merge Assist
feature is 8.5 ft (2.59 m). Trailer width is measured at the
widest portion of the trailer and may include wheels, tires,
finders, or rails.
NOTE:
Fifth wheel or gooseneck trailers are not supported by
Trailer Merge Assist.

SAFETY 221
NOTE:
• The Trailer Merge Alert system DOES NOT alert the driverabout rapidly approaching 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).
• Crowded areas such as parking lots, neighborhoods, etc. May lead to an increased amount of false alerts. This is
normal operation. General Information

Forward Collision Warning (FCW) With Mitigation — If
Equipped
The Forward Collision Warning (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 poten -
tial 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 as
well as a possible 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 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.

SAFETY 223
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 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.
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

224 SAFETY
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” 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”, this 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.
• When FCW status is set to “Only Warning”, this prevents the system 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” for further information.
• Far
• When the sensitivity of FCW is set to the “Far” settingand the system status is “Only Warning “, 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.
