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.
Blind Spot Assist Cameras
There are cameras located in the exterior mirrors to
assist in blind spot detection. Refer to
page 145 to
learn more about how the cameras function with turn
signal engagement or refer to
page 147 to learn
how to activate the cameras through the camera's
screen.
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 system. This will
prompt the trailer selection menu again to allow for the
correct selection.
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
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 174.
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
(e.g. 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 rear-
ward most portion of the body, fascia/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.
