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 appro-
priate 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 — If Equipped
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.
NOTE:
When Trailer Merge Assist is activated, Rear Cross Path
is disabled.
Trailer Merge Assist consists of three sub functions:
•
Automatic Trailer Detection
•
Trailer Length Detection
•
Trailer Merge Warning
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 auto-
matically determine the presence and length of a
trailer. The presence of a trailer will be detected
using the blind spot radar within 90 seconds of for-
ward movement of the vehicle. The vehicle must be
moving above 6 mph (10 km/h) to activate the fea-
ture. 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
.
•
Maximum 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 placed in
the OFF position. To change this setting, it must be
selected through the Uconnect Settings
page 135.
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.
The maximum trailer 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, fascia/
bumper, or ramp of the trailer.
