SAFETY 297
Blind Spot Alert Off
When the BSM system is turned off there will be no
visu
al 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 – If Equipped
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.
NOTE:
When Trailer Merge Assist is activated, Rear Cross
Path
is disabled.
Trailer Merge Assist consists of three sub
func
tions:
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
t
h
e trailer length:
Automatic Mode — When “Auto Mode” is
selected, the system will use the blind spot
sensors to automatically determine the pres
-
ence and length of a trailer. The presence of a
trai
ler will be detected using the blind spot radar
within 90 seconds of forward movement of the
vehicle. 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
.
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
plac
ed in the OFF position. To change this setting,
it must be selected through the Uconnect settings
Ú page 216.
Trailer Length Detection
Once the trailer presence has been established,
t
he
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
disp
layed. This can take up to 30 seconds after
completing the turn.
NOTE:
During the same ignition cycle, if the vehicle is at a
stan
dstill for a minimum of 90 seconds, a new
“trailer detection request” is enabled by the
system once the vehicle resumes motion.
