WHAT IS TRAILER BACKUP
ASSISTANCE
Trailer backup assistance utilizes the
control knob on the instrument panel to
help you steer a trailer. Turn the control
knob in the direction you want the trailer
to go and the system steers the vehicle.
HOW DOES TRAILER BACKUP
ASSISTANCE WORK
Trailer backup assistance uses a sticker or
sensor attached to the trailer to detect the
trailer angle relative to the towing vehicle
and provides instructions, graphics and
camera views on the touchscreen.
TRAILER BACKUP

Note:
Make sure the arrows on the sensor
housing are facing up. Mount the sensor to
a vertical part of the trailer that pivots and
moves when you turn your vehicle. Do not
mount to a stationary surface or to the truck
side of the fifth wheel-trailer hitch.
Note: You need to replace the 7/4 way
connector in the bumper with the
recommended 7/12 pin connector if your
vehicle did not come with the fifth-wheel
prep package. See your authorized dealer.
Note: If your vehicle has the fifth-wheel
prep package, you have everything you need.
If your vehicle does not have the fifth-wheel
prep package, see your authorized dealer to
purchase the sensor kit and the 7/12 pin
connector.
CALIBRATING THE SYSTEM
Calibrating the system requires driving
forward and turning left or right. Follow the
instructions on the instrument cluster
display and touchscreen to complete the
calibration process. Note:
Calibrating the system requires an
area where you can safely drive forward and
turn left or right. An open parking lot is an
ideal place to perform the calibration. Note:
Keep the steering wheel straight
when instructed to by the instrument cluster
display and touchscreen. If the steering
wheel is in a turned position during this
instruction, the calibration pauses.
Note: During calibration, the system
determines the trailer length. The system
supports trailer lengths of 10– 39 ft
(3– 11.94 m) distance from the hitch point
to the center of the axle or axles.
Note: The instrument cluster displays and
touchscreen shows if you are going too slow
or fast. Calibration pauses if the speed is
outside the required range of
2 – 16 mph
(4– 25 km/h).
Note: You need to complete at least a 90°
turn, and longer trailers could require a 180°
turn.

Why does the trailer not reverse
straight when using a conventional
trailer?
Factors such as the drawbar
connection to the hitch receiver, road
camber, road grade and compliance
in the trailer suspension can influence
how straight the system is able to
reverse your trailer when the knob is
not turned. You can compensate for
the trailer drifting to the right or left by
slowly turning the knob until the trailer
is following your preferred path and
then holding the knob in that position.
If you would like to recalibrate the
system for straight backing, change
the sticker option in the instrument
cluster display. Confirm the
measurements, and the system
prompts you to perform the calibration
procedure.
Why does the trailer not reverse
straight when using a fifth-wheel or
gooseneck trailer? Verify the sensor is correctly installed.
Other factors such as the hitch
connection, road camber, road slope
and trailer suspension could influence
how straight the system can reverse
the trailer when the control knob is not
turned. You can compensate for the
trailer drifting to the right or left by
slowly turning the knob until the trailer
is following your desired path and then
holding the knob in that position. Why does the system not detect a
sensor?
There could be an issue with the
connection, the wiring harness could
be damaged, you could have multiple
sensors connected or the sensor could
be incorrectly installed. Check that the
12-way connector is fully inserted into
the 12-way socket. The red rubber seal
is not visible when the connector is
fully inserted. Also check that the
wiring harness sensor connection is
fully inserted at the trailer sensor, and
check for damaged wiring between
the 12-way connector and the trailer
sensor. Also, check that the sensor is
installed on a vertical surface with the
arrows pointing straight up.
What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with a
conventional trailer? The camera could need to be cleaned,
the sticker could be blocked, the
drawbar could be outside the allowed
range of 4–19 in (10–48 cm) or you
could need to move to a different area
to change the lighting and background.
Verify the sticker is in the proper
location. See
Applying the Trailer
Reversing Aid Sticker (page 341).
You can move to a different area or
change the direction you are driving or
setup the system at a different time
of day. Some trailers are not
compatible with the sticker and
camera system.
What does it mean if the system pauses
during calibration? There could be steering input or trailer
movement during the straight drive
portion of the calibration process.

What does it mean if the system
remains on one message for an
extended time during calibration when
setting up the system with a
fifth-wheel or gooseneck trailer?
The sensor could be incorrectly
installed, the trailer length could be
outside the allowed range or the road
surface could be too rough or bumpy.
What does it mean if the system
displays hold steering steady during
turn? Part of the calibration process for the
sticker setup requires a steady turn. If
you are continually moving the
steering wheel during the turn, this
delays the calibration process. To
enable the calibration process, hold
the steering wheel at the same
position when turning.
What does it mean if the system
displays that it is not available? There could be a sub-system that the
system uses that is not correctly
operating or there could be a battery
voltage issue. If the system continues
to display it is not available, visit your
authorized dealer to have your vehicle
checked.
What does it mean if the system
displays that driving is required to
initialize steering? The steering system needs to learn
internal parameters to fully turn on the
feature. Drive your vehicle straight
forward above 25 mph (40 km/h) for
approximately 5 minutes. This could
also occur when your vehicle is new,
there is a battery voltage issue or if the
steering system has been serviced. What does it mean if the system does
not detect a trailer when configured for
a fifth-wheel or gooseneck trailer?
Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 344). Repeat
calibration on a different route if you
have verified sensor installation.
What does it mean if the system
requires you to pull forward to
initialize? This occurs when the vehicle has not
moved during the current key cycle
after you connect and select the trailer
in the instrument cluster display or you
operate the system at speeds below
1 mph (1 km/h)
for an extended period
of time. Drive forward above 2 mph
(3 km/h) and the system indicates
when it initializes.

What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle when using
a conventional trailer?
The system uses your measurements
to determine sticker position and
establish system limits. Accurate
sticker placement and trailer
measurements provide the best
system performance. If you are
consistently receiving this warning, it
is likely there is an issue with sticker
placement or the entered
measurements. Make sure that the
sticker is placed correctly and the
measurements were made correctly.
See Applying the Trailer Reversing
Aid Sticker (page 341). To change the
sticker location or change trailer
measurements, change the sticker
option in the instrument cluster
display. If the sticker location needs to
be changed, the previous sticker must
be removed and a new sticker needs
to be placed on the trailer. Only one
sticker should be placed on the trailer
for proper system function. What does it mean if the trailer is at its
maximum angle or the system
deactivated by trailer angle when using
a fifth-wheel or gooseneck trailer?
You are at the maximum controllable
trailer angle for the system. Place your
vehicle in drive (D) and pull forward to
get the truck and trailer back to an
in-line position. If this message
consistently displays, this could
indicate the sensor is incorrectly
installed, the trailer needs to be
recalibrated or the drawbar or the
trailer dimensions are outside of the
supported range. The system is
designed to work with drawbars that
have a license plate to hitch ball center
measurement of 9– 20 in (23–52 cm)
when installed. The system is designed
to work with trailers that have a hitch
point to center of the axle or axles
measurement of
6– 33 ft
(1.85– 10.05 m). Do not attempt to use
drawbars or trailers that have a length
outside of this range as the system
performance degrades and could
cause improper system function.
Check that the correct trailer is
selected in the instrument cluster
display. Verify the sensor is installed
according to the instructions included
in the sensor kit and check that the
drawbar and the trailer dimensions are
within the allowed range. Then, delete
the trailer from the system and repeat
the setup process to calibrate the
trailer.
