Traction Control System (TCS)
This system monitors the amount of wheel spin
of each of the driven wheels. If wheel spin is
detected, the Traction Control System (TCS)
may apply brake pressure to the spinning
wheel(s) and/or reduce engine power to provide
enhanced acceleration and stability. A feature
of the TCS, Brake Limited Differential (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 power 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 excessively
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 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.
AUXILIARY DRIVING SYSTEMS
Blind Spot Monitoring (BSM) — If Equipped
The Blind Spot Monitoring (BSM) system uses
two radar-based sensors, located inside the tail -
lights, 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
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 standby 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 detec -
tion zones on both sides of the vehicle when the
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.

154SAFETY
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 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).
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 contamination 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 illumi -
nated 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 ignition 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 informa-
tion.

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 neces -
sary. The BSM system will issue an alert during
these types of zone entries.

20_DJD2_OM_EN_USC_t.book Page 154

156SAFETY
The BSM system will not alert you of objects that
are traveling 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 (5 km/h), to
objects moving a maximum of approximately
20 mph (32 km/h), such as in parking lot situa -
tions. 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.
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.
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.

Modes Of Operation
Three selectable modes of operation are avail -
able 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 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 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.
NOTE:
When a trailer with an electric brake is
connected to the vehicle, the instrument cluster
display will provide a menu to allow a selection
of the trailer type. There will be two options
provided: Conventional and Goose/Fifth Wheel.
Goose/Fifth Wheel Trailer is incompatible and
when selected, the BSM system will disable
until the trailer is disconnected. If the wrong
option is selected, the system can be reset by
either disconnecting and reconnecting the
trailer harness connector or disabling then
re-enabling the Blind Spot Monitoring System in
the customer settings in the Uconnect. This will
prompt the trailer selection menu again to allow
for the correct selection.
Trailer Merge Assist is a function of the Blind
Spot Monitoring (BSM) system that extends the
blind spot zone to work while pulling a trailer.
Trailer Merge Assist consists of three sub func
-
tions:Automatic Trailer Detection
Trailer Length Detection
Trailer Merge Warning

20_DJD2_OM_EN_USC_t.book Page 157

SAFETY159
Trailer length will be identified and placed into
one of the following categories:
Trailer length up to 10 ft (3 m) — Blind spot
zone will be adjusted to 10 ft (3 m) .
Trailer length between 10 ft to 20 ft (3 m to
6 m) — Blind spot zone will be adjusted to
20 ft (6 m) .
Trailer length between 20 ft to 30 ft (6 m to
9 m) — Blind spot zone will be adjusted to
30 ft (9 m) .
Trailer length between 30 ft and 39.5 ft (9 m
to 12 m) — Blind spot zone will be adjusted to
MAX distance .
NOTE:
Trailer length is determined within +/- 3 ft (1 m)
of actual length. Trailers that are the same size
as the category limit, 10/20/30 ft (3/6/9 m),
could be subject to being placed in the category
above or below the correct one.
Trailer Merge Warning
Trailer Merge Warning is the extension of the
blind spot function to cover the length of the
trailer, plus a safety margin, to warn the driver
when there is a vehicle in the adjacent lane. The
driver is alerted by the illumination of the BSM warning light located in the outside mirror on
the side the other vehicle is detected. In addi
-
tion, an audible (chime) alert will be heard and
radio volume reduced. Refer to “Modes Of Oper -
ation” in this section for further information.
NOTE:
The Trailer Merge Alert system DOES NOT
alert the driver about 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, neigh -
borhoods, etc. May lead to an increased
amount of false alerts. This is normal opera -
tion.
