consi
dered the forward most portion of the trailer
hitch to the rearward most portion of the body,
fascia/bumper, or ramp of the trailer.

by T
railer Merge Assist.
NOTE:
The ability to detect a trailer may be degraded in
crowd
ed or busy environments. Busy parking lots,
narrow areas surrounded with trees, or any other
crowded area may prevent the radar sensors from
being able to adequately detect the trailer. The
system will try to detect a trailer at every ignition
cycle or 90 seconds of standstill.
Trailer Length Detection
Trailer length will be identified and placed into one
of th
e following categories:
Trailer length up to 10 ft (3 m) — Blind spot zone
will be adjusted to 10

Trailer length between 10 ft to 20 ft (3 m to
6 m) — Blind spot zone will be adjusted to 20 ft
(6

.
Trailer length between 20 ft to 30 ft (6 m to

d
i
s
t
ance .
NOTE:
Trailer length is determined within +/- 3 ft (1 m) of
actu
al length. Trailers that are the same size as the
category limit, 10/20/30
ft (3/6/9 m), could be
subj
ect 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 on. In addition, an audible (chime) alert
will be heard and radio volume will be reduced
Ú page 296.
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, neighbor-
hoods, etc. may lead to an increased amount of
f
a
l
s
e alerts. This is normal operation.
