Cargo Camera With Dynamic Centerline — If Equipped
The Dynamic Centerline feature provides an overlay on the
Cargo Camera display screen that aligns to the center of the
pickup box to aid in hooking up a fifth wheel camper or
gooseneck trailer. The centerline auto aligns to the center of
the pickup box, and can also be manually adjusted. The
centerline will adjust in response to steering angle inputs,
and will not obstruct the gooseneck receiver or an
approaching trailer gooseneck in the camera feed. Activation
The Dynamic Centerline feature can be activated through the
Uconnect settings by pressing the Cargo Camera soft button,
followed by the “Dynamic Centerline” soft button on the
touchscreen.
If the Dynamic Centerline feature is turned on, the overlay
will display anytime the Cargo Camera image is displayed.
Adjusting Centerline
Follow the steps below to manually adjust the centerline:
1. Press the “Adjust Centerline” soft button located in the
bottom right corner of the Cargo Camera display.
2. Use the arrows on the bottom left corner of the Cargo Camera display to adjust the centerline horizontally or
vertically.

3. Once the desired position is achieved, press the “Accept” button to set the centerline to the newly specified position.

Deactivation

The Dynamic Centerline feature will automatically be deacti -
vated whenever the Cargo Camera display is deactivated. It can
also be manually deactivated through the Uconnect settings.

STARTING AND OPERATING 413
Tongue Weight (TW)
The tongue weight is the downward force exerted on the
hitch ball by the trailer. You must consider this as part of the
load on your vehicle.
Trailer Frontal Area
The frontal area is the maximum height multiplied by the
maximum width of the front of a trailer.
Trailer Sway Control
The trailer sway control can be a mechanical telescoping link
that can be installed between the hitch receiver and the
trailer tongue that typically provides adjustable friction asso-
ciated with the telescoping motion to dampen any unwanted
trailer swaying motions while traveling.
If equipped, the electronic Trailer Sway Control (TSC) recog -
nizes a swaying trailer and automatically applies individual
wheel brakes and/or reduces engine power to attempt to
eliminate the trailer sway. Weight-Carrying Hitch
A weight-carrying hitch supports the trailer tongue weight,
just as if it were luggage located at a hitch ball or some other
connecting point of the vehicle. These kinds of hitches are the
most popular on the market today and they are commonly
used to tow small and medium sized trailers.
Weight-Distributing Hitch
A weight-distributing system works by applying leverage
through spring (load) bars. They are typically used for
heavier loads to distribute trailer tongue weight to the tow
vehicle's front axle and the trailer axle(s). When used in
accordance with the manufacturer's directions, it provides
for a more level ride, offering more consistent steering and
brake control, thereby enhancing towing safety. The addi
-
tion of a friction/hydraulic sway control also dampens sway
caused by traffic and crosswinds and contributes positively
to tow vehicle and trailer stability. Trailer sway control and
a weight distributing (load equalizing) hitch are recom -
mended for heavier Tongue Weights (TW) and may be
required depending on vehicle and trailer configuration/
loading to comply with GAWR requirements.

6. Perform a visual inspection of the trailer and weightdistributing hitch to confirm manufacturers’ recommen -
dations have been met.
NOTE:
For all towing conditions, we recommend towing with tow
haul mode engaged.
Towing With All Other 2500/3500 (Non-Air Suspension)
1. Position the truck to be ready to connect to the trailer (do not connect the trailer).
2. Measure the height of the top of the front wheel opening on the fender to ground, this is height H1.
3. Attach the trailer to the vehicle without the weight distri -
bution bars connected. 4. Measure the height of the top of the front wheel opening
on the fender to ground, this is height H2.
5. Install and adjust the tension in the weight distributing bars per the manufacturers’ recommendations so that the
height of the front fender is approximately (H2-H1)/
2+H1 (about 1/2 the difference between H2 and H1 above
normal ride height [H1]).
6. Perform a visual inspection of the trailer and weight distributing hitch to confirm manufacturers’ recommen -
dations have been met.
NOTE:
For all towing conditions, we recommend towing with tow
haul mode engaged.

The trailer and the vehicle’s stop lamps will come on when
braking normally with the vehicle brake pedal. Only the
trailer stop lamps will come on when the manual brake
control lever is applied.
Trailer Brake Status Indicator Light
This light indicates the trailer electrical connection status.
If no electrical connection is detected after the ignition is
turned on, pushing the GAIN adjustment button or sliding
the manual brake control lever will display the GAIN setting
for 10 seconds and the “Trailer Brake Status Indicator Light”
will not be displayed.
If a fault is detected in the trailer wiring or the Integrated
Trailer Brake Module (ITBM), the “Trailer Brake Status Indi-
cator Light” will flash.
GAIN Adjustment Buttons (+/-)
Pushing these buttons will adjust the brake control power
output to the trailer brakes in 0.5 increments. The GAIN
setting can be increased to a maximum of 10 or decreased to
a minimum of 0 (no trailer braking). GAIN
The GAIN setting is used to set the trailer brake control for
the specific towing condition and should be changed as
towing conditions change. Changes to towing conditions
include trailer load, vehicle load, road conditions and
weather.
Adjusting GAIN
NOTE:
This should only be performed in a traffic free environment
at speeds of approximately 20–25 mph (30–40 km/h).
1. Make sure the trailer brakes are in good working condi
-
tion, functioning normally and properly adjusted. See
your trailer dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the trailer manufacturer's instructions.
3. When a trailer with electric/EOH brakes is plugged in, the trailer connected message should appear in the
instrument cluster display (if the connection is not recog -
nized by the ITBM, braking functions will not be avail -
able), the GAIN setting will illuminate and the correct
type of trailer must be selected from the instrument
cluster display options.
