TRAILER REVERSING AIDS (IF
EQUIPPED)
Pro Trailer Backup Assist™ 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.
Note: You must always be aware of the
vehicle and trailer combination and the
surrounding environment.
Note: The system does not detect or prevent
the vehicle or trailer from making contact
with obstacles in the surrounding
environment.
Note: Keep in mind that the front end of the
vehicle swings out when changing the
direction of the trailer. Note:
The system relies on user
measurements to determine sticker
placement and system limits. It is critical to
take the key measurements correctly.
Incorrect measurements can result in the
improper function of the system up to and
including contact between the vehicle and
trailer.
Note: The system limits vehicle speed when
backing up. The system is not a replacement
for proper use of the throttle and brake
pedals.
Principle of Operation
This feature helps you to steer your vehicle
when reversing with a trailer attached. Turn
and hold the control knob in the direction
you want the trailer to go and the system
takes over the steering. This allows you to
focus on checking the mirrors and operating
the brake and accelerator.

You have to set up each trailer you use with
your vehicle. You must accurately follow the
setup process to make sure you correctly
place the sticker.
Contact your dealership if you need
assistance in setting up your trailer.
Setting Up Pro Trailer Backup Assist
Note:
Once you enter a trailer's information,
the system stores it for easy recall. You can
add a maximum of 10 trailers to the system.
Step 1: Position your Vehicle and Trailer
Hitch the conventional trailer to your vehicle.
See Essential Towing Checks (page 326).
Park your vehicle and trailer on a level
surface. For best results, make sure that your trailer
rides level with the ground when you hitch
your vehicle. More information on selecting
your tow bar is available in the Towing
section.
See Towing (page 311).
Make sure your vehicle and the trailer are in
line with each other. You can do this by
driving straight forward.
Step 2: Follow the Information Display
Prompts
Press the button to turn the system on.
1. Select the option to add a trailer in the
information display using the steering
wheel control.
See General Information
(page 133).

2. Add a personalized name for the trailer
using the screen prompts. Use the down
arrow to scroll to the desired letter and
then press the toggle switch to advance
to the next letter. Press OK to continue.
3. Select the type of trailer brake system for
the trailer you are adding.
4. Select the brake effort level for the trailer.
Note: The default option is low. We
recommend this for most trailers. If the
trailer's brakes require more initial voltage,
or if you prefer more aggressive braking,
then select the other options as required.
Some examples of conventional type trailers
are below.
Note: You cannot use the system with the
types of trailers marked with the cross. The system only works with conventional
trailers. It does not work with other types
including goose neck and fifth wheel.
Follow the information display prompts.
Step 3: Place the Sticker on the Trailer
Frame
You must place the supplied sticker in an
area visible by the rear view camera.
Note:
An assistant can help to carry out the
following procedure. Note:
Make sure nothing can obstruct the
rear view cameras view of the sticker. For
example, items 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 you position
them. Do not re-use any stickers if removed.
Note: You can purchase additional stickers
through your authorized dealer. 314
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing TowingE209766 E209805

Use the supplied measurement card, a tape
measure and pen to carefully mark the area
where to attach the sticker (supplied in the
back cover pocket of your quick start guide).
Make sure the whole sticker is within the
zone between the two arcs or distance
markers on the diagram, and is also visible
in the rear view camera display.
Step 4: Take Measurements
After you correctly place the sticker on the
trailer, you must take some key
measurements.
Note:
You must take accurate
measurements for the system to operate
properly.
Note: When rounding in inches, round
upward if the measured length is a quarter
inch or greater. Round downward if the
measured length is less than a quarter inch.
For example 12.25 in (31.11 cm) would be
rounded up to 12.50 in (31.75 cm). 12.13 in
(30.8 cm) would be rounded down to 12.00 in
(30.48 cm)
. Note:
When rounding in centimeters, round
to the nearest whole centimeter. If the
measurement is less than
0.2 in (0.5 cm)
round downward. If the measurement is
more than or equal to
0.2 in (0.5 cm) round
upward. For example, 11.9 in (30.3 cm) would
be rounded down to 11.8 in (30 cm). 12.0 in
(30.5 cm) would be rounded up to 12.2 in
(31 cm).
Note: Use consistent metric or imperial units
as required by your country or vehicle.
Record the four key distances (A, B, C, D) as
required by the measurement card. Record
the trailer name for these measurements. Distance A
The horizontal distance from the bumper to
the center of the ball hitch on the trailer.
Distance B
The horizontal distance from the center of
the ball hitch to the center of the sticker.
Distance C
The distance from the rear view camera to
the center of the sticker.
315
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing TowingE247545

Distance D
The horizontal distance from the bumper to
the center of the trailer axle (single axle
trailers), or the center of the axles (trailers
with dual axles or more).
Note:
If the distance ends in anything less
than one half of an inch, round down to the
current whole inch. If a distance ends in one
half or greater of an inch, round up to the
next whole inch. For example, 12.3 in
(31.12 cm) would be rounded down to 12 in
(30.48 cm). 12.5 in (31.75 cm) would be
rounded up to 13 in (33 cm).
Step 5: Enter Measurements Using the
Information Display
Using the recorded measurements, enter the
required data into the system. Follow the on
screen prompts to enter each of the
measurements taken in step 4. When all four
distances have been entered, a confirmation
display will appear. Check the values are
correct before proceeding, or go back to
change any if required. Step 6: Confirming the Sticker Location
Check the rear view camera display to see
if the sticker is identified by the system and
marked with a red circle.
Confirm that the red circle is correctly located
over the sticker image in the display. The on
screen prompt will ask you to confirm this.
Note:
If the system cannot locate the sticker
try cleaning the camera lens, and also make
sure the sticker is within the green zone as
indicated in step 3.
Calibrating the System
To complete setup, drive your vehicle
straight forward between 4 mph (6 km/h) and
24 mph (39 km/h)
following the on screen
prompt.
Note: Check your measurements to make
sure you measured from the correct points.
Note: If you move the steering wheel during
this procedure, the calibration pauses.
Note: We recommend that you do not do
this at night. A message will be displayed during
calibration and after calibration is complete.
Using Pro Trailer Backup Assist
To use the system press the button and
select the required trailer from the display.
316
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

When the sticker is located, the display
prompts you to shift into reverse (R). The
system turns on. Note:
The system does not function if your
hands are on the steering wheel. Remove
your hands to resume operation.
Follow the screen prompts to steer your
vehicle and trailer.
Note: You may have to drive forward to
straighten the trailer.
Take your hands off the steering wheel and
turn the Pro Trailer Backup Assist control
knob instead. The knob acts as the steering
control for the trailer.
Note: The more you turn the knob, the
sharper the trailer turns. Turn and hold counterclockwise to make the
trailer go left. Turn and hold clockwise to make the trailer
go right.
Note:
Practice maneuvering with the system
in a safe open area first.
Note: Try backing up in a straight line and
then turning the knob slowly in the direction
you want to go.
Note: Quickly turning and releasing the knob
results in a jerky movement of the vehicle. 317
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing TowingE246984 E246992 E246991 E246993

Release the knob when the trailer is moving
in the direction you want. Control the
accelerator and brakes while the system
steers your vehicle automatically to keep the
trailer moving straight back.
Note:
You may have to use the knob to
correct the trailer direction when attempting
to move the trailer straight back under some
conditions.
Note: Your vehicle speed is automatically
limited.
Note: When you release the knob or turn it
to the center position, your vehicle follows
the trailer's path.
Troubleshooting
Note: 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 operate correctly. Setup
The system is designed to be used with a
wide variety of trailers. However there are
some trailers that do not have a proper
surface and location to mount the sticker.
These trailers are not supported. Attempts
to place the sticker on a surface that does
not meet the sticker placement requirement
listed in Step 3 of the setup instruction or
entering inaccurate measurements to
proceed through setup can result in improper
system function.
Accurate measurements are critical to correct
system function. If you need to check
measurements entered or change them you
can access them through the trailer menus
in the instrument cluster. Choose the option
to change the sticker from the change trailer
settings menu. It is not necessary to remove
the sticker if you are just reviewing or
changing measurements.
The following menu warnings or difficulties
may occur during setup. Tips to resolve them
are listed below.Note:
If you still experience issues with the
system's ability to detect the sticker, see the
information in the next section regarding
sticker lost during system operation.
Measurement A has reached maximum or
minimum value:
• The system is designed to work with
drawbars that have a bumper to hitch ball
center measurement of 4 in (10 cm) to
11 in (28 cm) when installed. Do not
attempt to use drawbars that have a
length outside this range as the system
performance will be degraded and could
cause improper system function.
• Make sure that the measurement being
made is the horizontal distance only from
bumper and the hitch ball center. A
straight line distance that includes any
vertical rise or drop will increase the
measurement and make it inaccurate.
Inaccurate measurements will degrade
system performance and could cause
improper system function. See step 4 of
the setup instruction to review
measurement instructions.
318
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

Measurement B has reached maximum or
minimum value:
•
Make sure that the sticker placement
instruction in step 3 of the setup has
been followed. Stickers placed outside
the allowed zone will adversely affect the
system performance and could cause
improper feature function.
• Make sure that the measurement being
made is the horizontal distance only from
center of sticker to the hitch ball center.
A straight line distance that includes any
vertical rise or drop will increase the
measurement and cause an inaccurate
value to be entered into the system. See
step 4 of the setup for additional
measurement instructions.
Measurement C has reached maximum or
minimum value:
• Make sure that the sticker placement
instructions in step 3 of the setup have
been followed. Stickers placed outside
the allowed zone will adversely affect the
system performance and could cause
improper feature function. If you have
met all the criteria for sticker placement
and you see this message this sticker is either too far below or too close to the
camera to properly recognize the sticker.
In order for the system to operate
correctly the sticker height must be
lowered if you receive the minimum
warning or the sticker height must be
raised if you receive the maximum
warning.
• Only one sticker can be placed on the
trailer for correct system function. The
previous sticker must be removed or
covered so only one sticker is visible to
the camera.
• Measurement B and C must be measured
again if a new sticker is placed on the
trailer.
Measurement D has reached maximum or
minimum value:
• Make sure that the measurement being
made is the horizontal distance only from
the bumper to the center of the single
axle or the center of all the axles on the
trailer. See step 4 of the setup for
additional measurement instructions. The
TBA system does not support trailer
lengths outside the range allowed by the
information display. System is circling something beside the
sticker or system cannot find the sticker:
•
Make sure the rear camera is clean and
the sticker is clearly visible in the camera
image. Clean the camera and sticker if
necessary.
• The camera system uses the entered
measurements to help locate the sticker.
Inaccurate sticker measurements will
degrade the system ’s ability to locate the
sticker. Verify the measurements entered
into the system are accurate.
• Remove the incorrectly circled label or
decal if possible.
• If you cannot resolve the issue a new
sticker location should be tried. The
sticker location must still meet the
requirements noted in step 3 of the setup
instructions. Only one sticker can be
placed on the trailer for correct system
function. The previous sticker must be
removed or covered so only one sticker
is visible to the camera.

Calibration
The system monitors various vehicle
parameters to ensure your vehicle is being
driven straight and the trailer straight behind
your vehicle. Any steering input or trailer
movement will pause the calibration.
For best results:
•
Use a long, straight, smooth and level
road when attempting to calibrate.
• Drive straight forward.
• Drive between 4 mph (6 km/h) and
24 mph (39 km/h).
System Operation
The following warnings or difficulties may
occur during feature operation. Tips to
resolve them are listed below. The system is not available:
•
The system relies on many sub-systems
in your vehicle to operate correctly. If
those sub-systems are not operating
correctly the system may not be
available.
• Low battery voltage is a condition which
will prevent the system from operating.
Please make sure the battery is correctly
charged if the system is not available.
• You may need to drive your vehicle
straight forward above 25 mph (40 km/h)
before the system is available again.
• If the message still displays take your
vehicle to an authorized dealer for
service.
Sticker lost:
• If the system cannot initially find the
sticker, it may be necessary for you to
change the lighting conditions by moving
the vehicle and trailer or waiting until
conditions change.
• Check for the following if you receive the
lost sticker message while using the
system. •
Stop your vehicle as soon as the
message displays.
• Make sure the sticker is visible and the
pattern is discernable in the rear view
camera image.
• Clean the sticker and camera to make
sure they are unobstructed.
• Clean the lens with a soft, lint-free cloth
and water.
• Clean the sticker with isopropyl rubbing
alcohol sprayed directly onto the sticker,
and then wipe clean with a soft cloth.
• Remove any items that may be blocking
the view of the sticker. Depending on
your trailer configuration and any
equipment mounted to your trailer it is
possible for the sticker to be blocked
from view of the camera as it rotates on
the hitch ball but not be blocked during
setup. Remove the obstruction if
possible. It will be necessary to remove
the sticker from it’ s current location if the
obstruction cannot be cleared and place
a new sticker that will be visible to the
camera in all positions of the trailer
behind your vehicle.
320
Navigator (TB9) Canada/United States of America, enUSA, Edition date: 201907, Second-Printing Towing

•
Placing the sticker on a surface angled
away from the vehicle reduces
performance. Use a drawbar that
positions the trailer level to the ground
when attached to vehicle. This typically
provides a level surface to mount the
sticker. Place the sticker on a bracket or
other object when no level surface is
available.
• Make sure the entire sticker is on a flat
surface that is completely visible to the
camera. Do not fold the sticker over an
edge on the trailer frame. This can
degrade performance.
• Shadows on the sticker may effect
tracking performance under some
lighting conditions. Moving the sticker to
another location within the allowed
placement area may improve
performance. Use the change sticker
option in your Towing menu if you move
the sticker. •
You can change your sticker location by
going into the Towing menu, selecting
trailer options, selecting change trailer
settings and then selecting the change
sticker option. The previous sticker must
be removed. ONLY ONE STICKER
SHOULD BE PLACED ON THE TRAILER
FOR CORRECT SYSTEM FUNCTION.
• The camera system uses the entered
measurements to help locate the sticker.
Inaccurate measurements will reduce the
system ’s ability to locate the sticker.
Check the measurements entered into
the system are correct. Refer to the step
4 of Pro trailer backup Assist setup for
instructions on measurements.
• You can change your measurement by
going into the Towing menu, selecting
trailer options, selecting change trailer
setting and then selecting the change
sticker option. Disregard the prompt to
remove this sticker and continue to the
next step if you only plan to update the
measurements for the current sticker
location. System will not backup straight:
•
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 back your trailer
when the knob is not turned. You can
compensate for the trailer drifting to the
right or left by slowly turning the Pro
Trailer Backup Assist knob until the trailer
is following your desired path and then
holding the knob in that position. If you
would like to recalibrate the system for
straight backing, you can do so with the
following procedure.
• Go into the Towing menu, select trailer
options, select change trailer setting and
then select the change sticker option.
Your saved measurements will be
displayed. Do not change them but
continue to confirm measurements. Once
you confirm the measurements, the
system will then prompt you to perform
the calibration procedure.
