8 mph (13 km/h) while in any gear selector
position, Zoom View is available. By pressing
the “magnifying glass” icon in the upper left of the display
screen, the image will zoom in to four times the standard
view. Pressing the icon a second time will return the view
to the standard Back Up Camera display.
When Zoom View is selected while the vehicle is in
REVERSE, then shifted to DRIVE, the camera delay view
will display the standard Back Up Camera view. If the
vehicle is then returned to REVERSE gear from DRIVE, the
Zoom View selection will automatically resume.
Shifting to NEUTRAL from any gear will maintain the
selected view (Zoom or Standard) as long as the vehicle
speed is below 8 mph (13 km/h).
If the vehicle is in PARK, Zoom View is available until the
gear selector is placed in DRIVE or REVERSE and speeds
are at or above 8 mph (13 km/h).
NOTE:
If the vehicle is in DRIVE, NEUTRAL, or REVERSE, and
speed is greater than or equal to 8 mph (13 km/h),
Zoom View is unavailable and the icon will appear gray.
While in Zoom View, the guidelines will not be visible.
VIEWING AT SPEED
When the vehicle is in PARK, NEUTRAL or
DRIVE, the Rear View Camera can be activated
with the Back Up Camera button in the Controls
menu. This feature allows the customer to
monitor the area directly behind the vehicle (or trailer, if
equipped) for up to 10 seconds while driving. If the vehicle
speed remains below 8 mph (13 km/h), the Rear View
Camera image will be displayed continuously until
deactivated via the touchscreen X button.
FAMCAM SYSTEM — IF EQUIPPED
The FamCam system consists of an interior monitoring
camera mounted on the headliner that allows the driver to
view cargo/passengers in the rear interior of the vehicle
through the Uconnect screen.
To activate the feature, press the FamCam
button in the Controls tab of the Vehicle menu.
The FamCam feature can also be accessed

WARNING!
Drivers must be careful when backing up even when
using the ParkView Rear Back Up Camera. Always
check carefully behind your vehicle, and be sure to
check for pedestrians, animals, other vehicles,
obstructions, or blind spots before backing up. You are
responsible for the safety of your surroundings and
must continue to pay attention while backing up.
Failure to do so can result in serious injury or death.
CAUTION!
To avoid vehicle damage, ParkView should only be
used as a parking aid. The ParkView camera is
unable to view every obstacle or object in your drive
path.
To avoid vehicle damage, the vehicle must be driven
slowly when using ParkView to be able to stop in time
when an obstacle is seen. It is recommended that
the driver look frequently over his/her shoulder when
using ParkView.

178STARTING AND OPERATING
VEHICLE LOADING
GROSS VEHICLE WEIGHT RATING
(GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR.
PAYLOAD
The payload of a vehicle is defined as the allowable weight
a vehicle can carry, including the weight of the driver, all
passengers, options and cargo.
GROSS AXLE WEIGHT RATING (GAWR)
The GAWR is the maximum permissible load on the front
and rear axles. The load must be distributed in the cargo
area so that the GAWR of each axle is not exceeded.
Each axle GAWR is determined by the components in the
system with the lowest load carrying capacity (axle,
springs, tires or wheels). Heavier axles, or suspension
components sometimes specified by purchasers for
increased durability, do not necessarily increase the
vehicle's GVWR or GAWR.
TIRE SIZE
The tire size on the Vehicle Certification Label represents
the actual tire size on your vehicle. Replacement tires
must be equal to the load capacity of this tire size.
RIM SIZE
This is the rim size that is appropriate for the tire size
listed.
INFLATION PRESSURE
This is the cold tire inflation pressure for your vehicle for
all loading conditions up to full GAWR.
CURB WEIGHT
The curb weight of a vehicle is defined as the total weight
of the vehicle with all fluids, including vehicle fuel, at full
capacity conditions, and with no occupants or cargo
loaded into the vehicle. The front and rear curb weight
values are determined by weighing your vehicle on a
commercial scale before any occupants or cargo are
added.
LOADING
The actual total weight and the weight of the front and rear
of your vehicle at the ground can best be determined by
weighing it when it is loaded and ready for operation.
The entire vehicle should first be weighed on a commercial
scale to ensure that the GVWR has not been exceeded.
The weight on the front and rear of the vehicle should then
be determined separately to be sure that the load is
properly distributed over the front and rear axles.
Weighing the vehicle may show that the GAWR of either
the front or rear axles has been exceeded but the total
load is within the specified GVWR. If so, weight must be shifted from front to rear or rear to
front as appropriate until the specified weight limitations
are met. Store the heavier items down low and be sure
that the weight is distributed equally. Stow all loose items
securely before driving.
NOTE:
Improper weight distributions can have an adverse
effect on the way your vehicle steers and handles and
the way the brakes operate.
Air suspension vehicle may limit off-road heights if
loaded beyond recommended values for vehicle GVWR
and GAWR.
TRAILER TOWING
In this section you will find safety tips and information on
limits to the type of towing you can reasonably do with your
vehicle. Before towing a trailer, carefully review this
information to tow your load as efficiently and safely as
possible.
To maintain the New Vehicle Limited Warranty coverage,
follow the requirements and recommendations in this
manual concerning vehicles used for trailer towing.
WARNING!
Do not load your vehicle any heavier than the GVWR or
the maximum front and rear GAWR. If you do, parts on
your vehicle can break, or it can change the way your
vehicle handles. This could cause you to lose control.
Overloading can shorten the life of your vehicle.

STARTING AND OPERATING179
COMMON TOWING DEFINITIONS
The following trailer towing related definitions will assist
you in understanding the following information:
Gross Vehicle Weight Rating (GVWR)
The GVWR is the total allowable weight of your vehicle.
This includes driver, passengers, cargo and tongue
weight. The total load must be limited so that you do not
exceed the GVWR
Úpage 178.
Gross Trailer Weight (GTW)
The GTW is the weight of the trailer plus the weight of all
cargo, consumables and equipment (permanent or
temporary) loaded in or on the trailer in its "loaded and
ready for operation" condition.
The recommended way to measure GTW is to put your fully
loaded trailer on a vehicle scale. The entire weight of the
trailer must be supported by the scale.
Gross Combination Weight Rating (GCWR)
The GCWR is the total allowable weight of your vehicle and
trailer when weighed in combination.
Gross Axle Weight Rating (GAWR)
The GAWR is the maximum capacity of the front and rear
axles. Distribute the load over the front and rear axles
evenly. Make sure that you do not exceed either front or
rear GAWR
Úpage 178.
Tongue Weight (TW)
The TW 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 (TSC)
The TSC can be a mechanical telescoping link that can be
installed between the hitch receiver and the trailer tongue
that typically provides adjustable friction associated with
the telescoping motion to dampen any unwanted trailer
swaying motions while traveling.
If equipped, the electronic TSC recognizes 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 used to tow small and medium sized trailers.
Weight-Distributing Hitch
A Weight-Distributing Hitch 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 addition 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 recommended for heavier Tongue
Weights (TW) and may be required depending on vehicle
and trailer configuration/loading to comply with Gross Axle
Weight Rating (GAWR) requirements.
WARNING!
If the gross trailer weight is 5,000 lb (2,267 kg) or
more, it is recommended to use a weight-distributing
hitch to ensure stable handling of your vehicle. If you
use a standard weight-carrying hitch, you could lose
control of your vehicle and cause a collision.
WARNING!
It is important that you do not exceed the maximum
front or rear GAWR. A dangerous driving condition can
result if either rating is exceeded. You could lose control
of the vehicle and have a collision.
WARNING!
An improperly adjusted Weight-Distributing Hitch
system may reduce handling, stability, braking
performance, and could result in a collision.
Weight-Distributing Hitch systems may not be
compatible with surge brake couplers. Consult with
your hitch and trailer manufacturer or a reputable
Recreational Vehicle dealer for additional
information.

TRAILER AND TONGUE WEIGHT
Never exceed the maximum tongue weight stamped on
your bumper or trailer hitch.
Weight Distribution
Consider the following items when computing the weight
on the rear axle of the vehicle:
The tongue weight of the trailer.
The weight of any other type of cargo or equipment put
in or on your vehicle.
The weight of the driver and all passengers.
NOTE:Remember that everything put into or on the trailer adds
to the load on your vehicle. Also, additional
factory-installed options or dealer-installed options must
be considered as part of the total load on your vehicle.
Refer to the Tire And Loading Information Placard for the
maximum combined weight of occupants and cargo for
your vehicle.
TOWING REQUIREMENTS
To promote proper break-in of the new vehicle drivetrain
components, the following guidelines are recommended. Perform the maintenance listed in the Scheduled
Servicing
Úpage 309. When towing a trailer, never
exceed the GAWR or GCWR ratings.
WARNING!
Always load a trailer with 60% of the weight in the front
of the trailer. This places 10% of the GTW on the tow
hitch of your vehicle. Loads balanced over the wheels or
heavier in the rear can cause the trailer to sway
severely side to side which will cause loss of control of
the vehicle and trailer. Failure to load trailers heavier in
front is the cause of many trailer collisions.CAUTION!
Do not tow a trailer at all during the first 500 miles
(805 km) the new vehicle is driven. The engine, axle
or other parts could be damaged.
Then, during the first 500 miles (805 km) that a
trailer is towed, do not drive over 50 mph (80 km/h)
and do not make starts at full throttle. This helps the
engine and other parts of the vehicle wear in at the
heavier loads.
WARNING!
Make certain that the load is secured in the trailer
and will not shift during travel. When trailering cargo
that is not fully secured, dynamic load shifts can
occur that may be difficult for the driver to control.
You could lose control of your vehicle and have a
collision.
When hauling cargo or towing a trailer, do not over -
load your vehicle or trailer. Overloading can cause a
loss of control, poor performance or damage to
brakes, axle, engine, transmission, steering, suspen -
sion, chassis structure or tires.
Safety chains must always be used between your
vehicle and trailer. Always connect the chains to the
hook retainers of the vehicle hitch. Cross the chains
under the trailer tongue and allow enough slack for
turning corners.
Vehicles with trailers should not be parked on a
grade. When parking, apply the parking brake on the
tow vehicle. Put the tow vehicle transmission in PARK
(P). For four-wheel drive vehicles, make sure the
transfer case is not in NEUTRAL (N). Always, block or
"chock" the trailer wheels.
GCWR must not be exceeded.

186STARTING AND OPERATING
Towing Requirements — Tires
Do not attempt to tow a trailer while using a compact
spare tire.
Do not drive more than 50 mph (80 km/h) when towing
while using a full-size spare tire.
Proper tire inflation pressures are essential to the safe
and satisfactory operation of your vehicle.
Check the trailer tires for proper tire inflation pressures
before trailer usage.
Check for signs of tire wear or visible tire damage
before towing a trailer.
Replacing tires with a higher load carrying capacity will
not increase the vehicle's GVWR and GAWR limits.
For further information
Úpage 349.
Towing Requirements — Trailer Brakes
Do not interconnect the hydraulic brake system or
vacuum system of your vehicle with that of the trailer.
This could cause inadequate braking and possible
personal injury.
An electronically actuated trailer brake controller is
required when towing a trailer with electronically actu -
ated brakes. When towing a trailer equipped with a
hydraulic surge actuated brake system, an electronic
brake controller is not required.
Trailer brakes are recommended for trailers over
1,000 lb (453 kg) and required for trailers in excess of
2,000 lb (907 kg).
Integrated Trailer Brake Module (ITBM) —
If Equipped
Your vehicle may have an ITBM for Electric and Electric
Over Hydraulic (EOH) trailer brakes. The controller is
located below the instrument panel on the right side of the
steering column.
NOTE:This module has been designed and verified with electric
trailer brakes and EOH systems. Some previous EOH
systems may not be compatible with ITBM.
Total weight must be distributed between the tow
vehicle and the trailer such that the following four
ratings are not exceeded :
GVWR
GTW
GAWR
Tongue weight rating for the trailer hitch utilized
WARNING!
WARNING!
Do not connect trailer brakes to your vehicle's
hydraulic brake lines. It can overload your brake
system and cause it to fail. You might not have
brakes when you need them and could have an acci -
dent.
Towing any trailer will increase your stopping
distance. When towing, you should allow for addi -
tional space between your vehicle and the vehicle in
front of you. Failure to do so could result in an
accident.
CAUTION!
If the trailer weighs more than 1,000 lb (453 kg)
loaded, it should have its own brakes and they should
be of adequate capacity. Failure to do this could lead to
accelerated brake lining wear, higher brake pedal
effort, and longer stopping distances.

STARTING AND OPERATING187
Integrated Trailer Brake Module (ITBM)
The user interface consists of the following:
Manual Brake Control Lever
Slide the manual brake control lever to the left to activate
power to the trailer's electric brakes independent of the
tow vehicle's brakes. If the manual brake control lever is
activated while the brake is also applied, the greater of the
two inputs determines the power sent to the trailer brakes.
The trailer and the vehicle's brake lamps will come on
when either vehicle braking or manual trailer brakes are
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 ITBM, the
Trailer Brake Status Indicator 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 condition, functioning normally and properly
adjusted. See a 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
recognized by the ITBM, braking functions will not be
available), the GAIN setting will illuminate and the
correct type of trailer must be selected from the
instrument cluster display options.
4. Push the UP or DOWN button on the steering wheel until “TRAILER TOW” appears on the screen.
5. Push the RIGHT arrow on the steering wheel to enter “TRAILER TOW”.
6. Push the UP or DOWN buttons until the “Trailer Brake Type” appears on the screen.
7. Push the RIGHT arrow and then push the UP or DOWN buttons until the proper Trailer Brake Type appears
on the screen.
8. In a traffic-free environment, tow the trailer on a dry, level surface at a speed of 20–25 mph
(30–40 km/h) and squeeze the manual brake
control lever completely.
9. If the trailer wheels lockup (indicated by squealing tires), reduce the GAIN setting; if the trailer wheels
turn freely, increase the GAIN setting.
Repeat steps 8 and 9 until the GAIN setting is at a point
just below trailer wheel lockup. If towing a heavier trailer,
trailer wheel lockup may not be attainable even with the
maximum GAIN setting of 10.
