Trailer Backup Guide

Trailer Backup Guide is a
system to assist when back-
ing up a trailer by providing
either (1) steering control to
assist backing up straight
(Straight Path Assist) or (2)
guidance for manual steer-
ing backup (Guidance
mode).

Trailer Backup Guide uses
the rear camera to detect
the trailer and a trailer hitch
light, which allows the
driver to use the system at
night time.

The system calculates the
trailer angle by image pro-
cessing from the rear cam-
era and calculates trailer
length and hitch length
during the trailer setup (cali-
bration) maneuver.

The system is designed to support

most trailers 6.6 ft. (2 m) to 26.2 ft.

(8 m) in length (length is defined

from the coupler center point for

the ball to the wheel axle [single

axle] or center of the wheel axles

[2 or more axles]) with ball mount

lengths between 4.5 in. (114.3

mm) and 18.5 in. (469.9 mm). Do

not attempt to use trailers or ball

mounts that have a length outside

of this range as the system perfor-

mance degrades and could cause

improper system function.
