GCW (Gross Combined Weight)– is the weight of the loaded vehicle
(GVW) plus the weight of the fully loaded trailer.
GCWR (Gross Combined Weight Rating) – is the maximum allowable
weight of the vehicle and the loaded trailer – including all cargo and
passengers – that the vehicle can handle without risking damage.
(Important: The towing vehicle’s braking system is rated for operation at
GVWR, not at GCWR.) Separate functional brakes should be used for
safe control of towed vehicles and for trailers where the GCW of the
towing vehicle plus the trailer exceed the GVWR of the towing vehicle.
The GCW must never exceed the GCWR.
Maximum Loaded Trailer Weight – is the highest possible weight of a
fully loaded trailer the vehicle can tow. It assumes a vehicle with only
mandatory options, no cargo (internal or external), a tongue load of
10–15% (conventional trailer) or king pin weight of 15–25% (fifth wheel
trailer), and driver only (150 lb. [68 kg]). Consult your authorized
dealer (or the RV and Trailer Towing Guide provided by your
authorized dealer) for more detailed information.
Tongue Load or Fifth Wheel King Pin Weight – refers to the amount
of the weight that a trailer pushes down on a trailer hitch.
Examples: For a 5,000 lb. (2,268 kg) conventional trailer, multiply 5,000
by 0.10 and 0.15 to obtain a proper tongue load range of 500 to 750 lb.
(227 to 340 kg). For an 11,500 lb. (5,216 kg) fifth wheel trailer, multiply
by 0.15 and 0.25 to obtain a proper king pin load range of 1,725 to
2,875 lb. (782 to 1,304 kg)
WARNING: Do not exceed the GVWR or the GAWR specified on
the Safety Compliance Certification Label.
WARNING: Do not use replacement tires with lower load
carrying capacities than the original tires because they may lower
the vehicle’s GVWR and GAWR limitations. Replacement tires with a
higher limit than the original tires do not increase the GVWR and
GAWR limitations.

WARNING:Exceeding any vehicle weight rating limitation could
result in serious damage to the vehicle and/or personal injury.
Steps for determining the correct load limit:
1. Locate the statement “The combined weight of occupants and cargo
should never exceed XXX kg or XXX lb.” on your vehicle’s placard.
2. Determine the combined weight of the driver and passengers that will
be riding in your vehicle.
3. Subtract the combined weight of the driver and passengers from XXX
kg or XXX lb.
4. The resulting figure equals the available amount of cargo and luggage
load capacity. For example, if the “XXX” amount equals 1,400 lb. and
there will be five 150 lb. passengers in your vehicle, the amount of
available cargo and luggage load capacity is 650 lb. (1400-750 (5 x 150)
= 650 lb.).
5. Determine the combined weight of luggage and cargo being loaded on
the vehicle. That weight may not safely exceed the available cargo and
luggage load capacity calculated in Step 4.
6. If your vehicle will be towing a trailer, load from your trailer will be
transferred to your vehicle. Consult this manual to determine how this
reduces the available cargo and luggage load capacity of your vehicle.
The following gives you a few examples on how to calculate the available
amount of cargo and luggage load capacity:
• Suppose your vehicle has a 1400 lb. (635 kg) cargo and luggage
capacity. You decide to go golfing. Is there enough load capacity to
carry you, 4 of your friends and all the golf bags? You and four friends
average 220 lb. (99 kg) each and the golf bags weigh approximately
30 lb. (13.5 kg) each. The calculation would be: 1400 - (5 x 220) - (5
x 30) = 1400 - 1100 - 150 = 150 lb. Yes, you have enough load
capacity in your vehicle to transport four friends and your golf bags.
In metric units, the calculation would be: 635 kg - (5 x 99 kg) - (5 x
13.5 kg) = 635 - 495 - 67.5 = 72.5 kg.
• Suppose your vehicle has a 1400 lb. (635 kg) cargo and luggage
capacity. You and one of your friends decide to pick up cement from
the local home improvement store to finish that patio you have been
planning for the past 2 years. Measuring the inside of the vehicle with
the rear seat folded down, you have room for 12-100 lb. (45 kg) bags
of cement. Do you have enough load capacity to transport the cement
to your home? If you and your friend each weigh 220 lb. (99 kg), the

POWER DEPLOYABLE RUNNING BOARDS (IF EQUIPPED)
WARNING:In extreme climates, excessive ice buildup may
occur, causing the running boards not to deploy. Be sure that the
running boards have deployed, and have finished moving before
attempting to step on them. The running boards will resume normal
function once the blockage is cleared.
WARNING: Turn off the running boards before jacking or placing
any object under the vehicle. Never place your hand between the
extended running board and the vehicle. A moving running board may
cause injury.
Note: Do not use the running boards, front and rear hinge assemblies,
running board motors, or the running board under body mounts to lift
the vehicle when jacking. Always use proper jacking points.
Note: The running boards may operate slower in cooler temperatures.
Debris such as mud, dirt and salt may become trapped in the running
board mechanism, possibly leading to unwanted noise. If this occurs,
manually set the running boards to the deployed position and flush the
system (in particular the front and rear hinge arms) with a high-pressure
car wash wand.
The running boards automatically
move when the doors are opened to
assist entering and exiting the
vehicle.
Automatic Power Deploy
The running boards will extend down and out when the doors are
opened.
Automatic Power Stow
The running boards will return to the stowed position after a two second
delay when the doors are closed.

Manual Power Deploy
To manually operate the running boards, refer to theInformation
Displays chapter.
• This feature can manually set the running boards in the deployed
(OUT) position for access to the roof.
• When running boards are manually set in the deployed position, they
will return to the stowed position and enter automatic mode when the
vehicle speed exceeds 5 mph (8 km/h).
Enable and Disable
To enable and disable the power running board feature, refer to the
Information Displays chapter.
• When this feature is disabled (OFF), the running boards will move to
the stowed position regardless of the position of the doors.
• When this feature is enabled (AUTO), the running boards will move
back to the correct positions based off of the door positions.
Bounce-Back
If an object is in the way of the moving running board, it will reverse
direction and move to the end of travel.

TOWING A TRAILER
WARNING:Do not exceed the GVWR or the GAWR specified on
the certification label.
WARNING: Towing trailers beyond the maximum recommended
gross trailer weight exceeds the limit of your vehicle and could
result in engine damage, transmission damage, structural damage, loss
of vehicle control, vehicle rollover and personal injury.
Note: For information on electrical items such as fuses or relays, see the
Fuses chapter.
The load capacity of your vehicle is designated by weight not volume.
You may not necessarily be able to use all available space when loading
your vehicle or trailer.
Towing a trailer places extra load on the engine, transmission, axle,
brakes, tires, and suspension. Inspect these components before, during
and after towing.
Load Placement
To help minimize how trailer movement affects your vehicle when
driving:
• Load the heaviest items closest to the trailer floor.
• Load the heaviest items centered between the left and right side
trailer tires.
• Load the heaviest items above the trailer axles or just slightly forward
toward the trailer tongue. Do not allow the final trailer tongue weight
to go above or below 10–15% of the loaded trailer weight.
• Select a tow bar with the correct rise or drop. When both the loaded
vehicle and trailer are connected, the trailer frame should be level, or
slightly angled down toward your vehicle, when viewed from the side.
When driving with a trailer or payload, a slight takeoff vibration or
shudder may be present due to the increased payload weight. You can
find more information about proper trailer loading and setting your
vehicle up for towing under Load limitin theLoad Carrying chapter.
You can also find information in the RV and Trailer Towing Guide
available at your authorized dealer.

TRAILER SWAY CONTROL
WARNING:Turning off trailer sway control increases the risk of
loss of vehicle control, serious injury or death. Ford does not
recommend disabling this feature except in situations where speed
reduction may be detrimental (such as hill climbing), the driver has
significant trailer towing experience, and can control trailer sway and
maintain safe operation.
Note: This feature does not prevent trailer sway, but reduces it once it
begins.
Note: This feature cannot stop all trailers from swaying.
Note: In some cases, if vehicle speed is too high, the system may turn
on multiple times, gradually reducing vehicle speed.
This feature applies your vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes and the message TRAILER SWAY
REDUCE SPEED appears in the information display. The first thing to
do is slow your vehicle down, then pull safely to the side of the road and
check for proper tongue load and trailer load distribution. See the Load
Carrying chapter for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note: Do not exceed the trailer weight for your vehicle configuration
listed in the chart below.
Note: Make sure to take into consideration trailer frontal area. Do not
exceed:
• 36.5 feet
2(3.39 meters2) trailer frontal area for vehicles equipped
with the standard towing package.
• 60.0 feet
2(5.57 meters2) trailer frontal area for vehicles equipped
with the optional Heavy Duty package.
Note: Exceeding this limitation may significantly reduce the
performance of your towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design helps optimize performance
and fuel economy.
Note: For high altitude operation, reduce the gross combined weight by
2% per 1000 feet (300 meters) starting at the 1000 foot (300 meter)
elevation point.

Note:Certain states require electric trailer brakes for trailers over a
specified weight. Be sure to check state regulations for this specified
weight. The maximum trailer weights listed may be limited to this
specified weight, as your vehicle’s electrical system may not include the
wiring connector needed to use electric trailer brakes.
Your vehicle may tow a trailer provided the maximum trailer weight is
less than or equal to the maximum trailer weight listed for your vehicle
configuration on the following chart.
To calculate the maximum loaded trailer weight for your vehicle:
1. Start with the gross combined weight rating for your vehicle model and axle ratio. See the following chart.
2. Subtract all of the following that apply to your vehicle: •Vehicle curb weight
• Hitch hardware weight, such as a draw bar, ball, locks or weight
distributing
• Driver weight
• Passenger(s) weight
• Payload, cargo and luggage weight
• Aftermarket equipment weight.
3. This equals the maximum loaded trailer weight for this combination.
Note: The trailer tongue load figures into the payload for your vehicle.
Reduce the total payload by the final trailer tongue weight.
Consult an authorized dealer to determine the maximum trailer weight
allowed for your vehicle if you are not sure.

ESSENTIAL TOWING CHECKS
Follow these guidelines for safe towing:
•Do not tow a trailer until you drive your vehicle at least 1000 miles
(1600 kilometers).
• Consult your local motor vehicle laws for towing a trailer.
• See the instructions included with towing accessories for the proper
installation and adjustment specifications.
• Service your vehicle more frequently if you tow a trailer. See your
scheduled maintenance information.
• If you use a rental trailer, follow the instructions the rental agency
gives you.
For load specification terms found on the tire label and Safety
Compliance label and for instructions on calculating your vehicle’s load,
refer to Load limit in theLoad Carrying chapter.
Remember to account for the trailer tongue weight as part of your
vehicle load when calculating the total vehicle weight.
Trailer Towing Connector (Vehicles with a Trailer Towing Package
and 7–Pin Connector) When attaching the trailer wiring
connector to your vehicle, only use
a proper fitting connector that
works with the vehicle and trailer
functions. If your vehicle has a
trailer towing package, it may have
a 7–pin connector. Some connectors
may have the SAE J2863 logo,
which confirms that it is the proper
wiring connector and works correctly with your vehicle.
