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
with a sensor? Verify that the sensor is properly
connected. See
Trailer Sensor
Installation (page 448). 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 touchscreen 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?
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
9–18 in (23–46 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 touchscreen. 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.

What does it mean when the system
tells you to take control of the steering
wheel?
The system is no longer steering the
vehicle and you must take over
steering. There are four reasons the
system could display this message.
The first reason the system could
display this message is that you have
touched the steering wheel when the
system is steering. The second reason
the system could display this message
is that you have exceeded the
maximum speed for the feature. The
third reason the system could display
this message is that the trailer is not
detected. The final reason the system
could display this message is that an
internal condition for system operation
is not met that requires your vehicle to
return to manual control of the
steering.
How do I use a sticker if I have
previously setup a trailer with the
sensor? Disconnect the sensor wiring and add
a new trailer to the system and follow
the instructions for setup with a
sticker. See Applying the Trailer
Reversing Aid Sticker (page 448). If
your vehicle does not support the
sticker option, the touchscreen
instructs you to install the sensor
again.
What if I want to use a sensor for the
trailer instead of a sticker? Install the sensor and connect the
sensor wiring before adding the new
trailer to the system. You must
connect the sensor before you add the
trailer. If your vehicle did not come with
a sensor, you can purchase one from
your authorized dealer. What does it mean if the system does
not detect a trailer that is setup with a
sticker?
The system requires a clear view of the
sticker placed on the trailer. You must
keep the camera lens and sticker clean
for the system to correctly operate. If
the system cannot initially detect the
trailer, it could be necessary for you to
change the lighting conditions by
moving your vehicle and trailer or
waiting until the conditions change.
See
Applying the Trailer Reversing
Aid Sticker (page 448). Some trailers
are not compatible with the sticker
and camera system. If the system
consistently does not detect the trailer
with the sticker setup, you may choose
to setup the trailer with a sensor.
Note: The system is designed to be used
with the same trailer connection every time
you choose the trailer from the touchscreen.
When using a different drawbar or a
different pin hole on drawbars with more
than one, connecting the drawbar to your
vehicle affects the trailer position and you
may need to repeat the trailer setup and
calibration process.

WHAT IS TRAILER REVERSE
GUIDANCE
Trailer reverse guidance provides views
and graphics on the touchscreen to help
you steer your vehicle when you backup a
trailer.
HOW DOES TRAILER REVERSE
GUIDANCE WORK
Trailer reverse guidance 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 REVERSE GUIDANCE
PRECAUTIONS
WARNING: Driving while distracted
can result in loss of vehicle control, crash
and injury. We strongly recommend that
you use extreme caution when using any
device that may take your focus off the
road. Your primary responsibility is the
safe operation of your vehicle. We
recommend against the use of any
hand-held device while driving and
encourage the use of voice-operated
systems when possible. Make sure you
are aware of all applicable local laws
that may affect the use of electronic
devices while driving. WARNING: This system is an extra
driving aid. It does not replace your
attention and judgment, or the need to
apply the brakes. This system does NOT
automatically brake your vehicle. If you
fail to press the brake pedal when
necessary, you may collide with another
vehicle. Note:
The system is not a substitute for
safe driving practices. Always be aware of
your vehicle and trailer combination, and
the surrounding environment.

prevent your vehicle or trailer from making
contact with obstacles in the surrounding
environment.
Note: The front end of your vehicle swings
out when changing the direction of the
trailer.
Note: In certain conditions, the trailer could
turn faster or the trailer angle could increase
more than anticipated. Always monitor the
clearance between the trailer and vehicle
and the surroundings.
SETTING UP TRAILER
REVERSE GUIDANCE FOR A
CONVENTIONAL TRAILER
CONFIGURING THE TRAILER
You must configure a trailer in the system
to use trailer reverse guidance. This is a
one-time setup process and the trailer
information is saved in the system for the
next time you use that trailer.
The system only works with conventional
trailers. It does not work with other types
including fifth-wheel and gooseneck. The
following illustration shows examples of
conventional trailers on the left-hand side.
Note: Trailer reverse guidance camera
views are available with no trailer setup.
However, complete functionality including
graphics and automatic view switching is
enabled by setup. Setup is required to
enable trailer backup assistance.

Positioning the Trailer
Hitch the trailer to your vehicle and
connect the electrical wiring harness.
Check to make sure that the wiring is
working. See Connecting a Trailer (page
424).
Park your vehicle and hitched trailer on a
level surface.
For best results, make sure that your trailer
rides level with the ground when you hitch
your vehicle. See
Connecting a Trailer
(page 424). Make sure that the trailer and your vehicle
are in line with each other. You can do this
by putting the transmission in drive (D) and
pulling straight forward.
Configuring the Trailer in the
Touchscreen
1. Shift to reverse (R).
2. Press the camera view button.
3. Press the trailer view icon.
4. Press
Add Trailer.
5. Follow the directions on the touchscreen to enter the trailer name
and trailer type, then proceed to the
sticker or sensor setup.
Note: If you configure the trailer and install
a sensor, the trailer is saved with that sensor
information. If you want to use this trailer
with the sticker, you need to delete the
trailer from the system and repeat the setup
process.
Note: Your vehicle has two options for the
trailer reversing aid setup. If your vehicle
came with a trailer sensor kit or if a message
displays to install a sensor, follow the sensor
installation instructions. See Trailer Sensor
Installation
(page 461). If your vehicle did
not come with a trailer sensor kit, follow the
sticker installation instructions. See
Applying the Trailer Reverse Aid Sticker
(page
461).
Note: If your vehicle came with a trailer
sensor kit, the vehicle will receive an update
that allows the system to operate with a
sensor or sticker. If your vehicle did not come
with a trailer sensor kit, your vehicle can be
setup using either method, but you need to
separately purchase the trailer sensor kit
from your authorized dealer.

APPLYING THE TRAILER
REVERSE AID STICKER
Place the sticker in an area visible by the
rear view camera. The entire sticker must
be within 4–
19 in (10–48 cm) from the
center of the hitch ball, as shown in the
following illustration. Use the supplied sticker placement card,
a tape measure and pen to carefully mark
the area to attach the sticker. The sticker
is in the back cover pocket of your quick
start guide. Make sure the entire sticker is
within the green zone between the two
arcs or distance markers on the diagram,
and is also visible in the rear view camera
display.
Once you have found the correct location,
place the sticker.
Note:
Make sure nothing can obstruct the
rear view camera's view of the sticker such
as a jack handle or wiring.
Note: Position the sticker on a flat, dry and
clean horizontal surface. For best results,
apply the sticker when temperatures are
above
32°F (0°C).
Note: Do not move stickers after placing
them. Do not re-use any stickers if removed.
Note: You can purchase additional stickers
through your authorized dealer. Note:
If you previously setup the trailer with
the trailer sensor, make sure it is not plugged
in before configuring the trailer and placing
the sticker.
TRAILER SENSOR INSTALLATION Refer to the instructions included with your
trailer sensor for detailed information
regarding installation.
Note:
Make sure the arrows on the sensor
housing are facing up. Mount the sensor to
a vertical part of the trailer that pivots when
you turn your vehicle. Do not mount to a
stationary surface such as the truck side of
the trailer hitch.

Note:
If your vehicle came with a trailer
sensor kit, the vehicle will receive an update
that allows the system to operate with a
sensor or sticker. If your vehicle did not come
with a trailer sensor kit, your vehicle can be
setup using either method, but you need to
separately purchase the trailer sensor kit
from your authorized dealer. Once your
vehicle is enabled for sticker setup, the
default setup for new trailers requires
placement of the sticker. To setup a trailer
with a sensor, install the sensor on the trailer
and plug the connector into the connector
in your bumper prior to configuring the
trailer. Trailers that were set up with a
sensor still require the sensor to function.
To change a trailer to use the sticker, delete
the trailer in the system and repeat the
trailer setup with the sticker.
CALIBRATING THE SYSTEM
Calibrating the system requires driving
forward and turning left or right. Follow the
instructions on the touchscreen to
complete the calibration process. Note:
To calibrate the system, you need 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 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 6– 33 ft
(1.85– 10.05 m) distance from the hitch
point to the center of the axle or axles. The
system is designed to work with drawbars
that have a license plate to hitch ball center
measurement of 9– 18 in (23–46 cm) when
installed. 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.
Note: The touchscreen shows if you are
going too slow or fast. Calibration pauses if
the speed is outside the required range of
2 –9 mph (4– 15 km/h)
.
Note: You need to complete at least a 90°
turn, and longer trailers could require a 180°
turn. Camera trailer tracking requires the
system to locate the hitch ball as well as
determine the trailer length. Some trailers
could require you to drive straight then turn
multiple times before calibration completes.
The touchscreen provides instructions and
notifies you when calibration completes.
Note: For best results, do not calibrate the
system at night when calibrating the system
with the sticker.
SWITCHING TRAILER
REVERSE GUIDANCE ON AND
OFF
Shift into reverse (R), press the rear
camera button to expand the menu, press
the trailer icon and use the touchscreen to
select the connected trailer.

TRAILER REVERSE GUIDANCE –
FREQUENTLY ASKED QUESTIONS
Why does the trailer not reverse
straight?
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 the sticker?
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
Reverse Aid Sticker (page 461). 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. If the
issue persists with the sticker setup,
you may choose to setup the trailer
with a sensor.
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 the sensor? 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.
