Trailer Length Detection
1 — Trailer Length
2 — Trailer Hitch
3 — Trailer Width
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 on. In
addition, an audible (chime) alert will be heard
and radio volume reduced Ú page 317.
.
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.
