GCW (Gross Combined Weight)
- is the Gross Vehicle Weight 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 Gross Vehicle
Weight Rating, not at Gross
Combined Weight Rating.)
Separate functional brakes should
be used for safe control of towed
vehicles and for trailers where the
Gross Combined Weight of the
towing vehicle plus the trailer
exceed the Gross Vehicle Weight
Rating of the towing vehicle. The
Gross Combined Weight must
never exceed the Gross
Combined Weight Rating.
Maximum Loaded Trailer
Weight -
is the highest possible
weight of a fully loaded trailer the
vehicle can tow. It assumes a
vehicle with mandatory options,
driver and front passenger weight
(150 pounds [68 kilograms]
each), no cargo weight (internal
or external) and a tongue load of
10– 15% (conventional trailer) or
king pin weight of 15– 25% (fifth
wheel trailer). Consult an
authorized dealer (or the RV and
Trailer Towing Guide available at
an 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 5000 pound
(2268 kilogram) conventional
trailer, multiply 5000 by 0.10 and
0.15 to obtain a proper tongue
load range of 500 to 750 pounds
(227 to 340 kilograms). For an
11500 pound (5216 kilogram) fifth
wheel trailer, multiply by 0.15 and
0.25 to obtain a proper king pin
load range of 1725 to 2875 pounds
(782 to 1304 kilograms). WARNINGS
Do not exceed the GVWR or
the GAWR specified on the
Safety Compliance Certification
Label. 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. 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:
97
E-Series (TE4) Canada/United States of America, enUSA, Edition date: 03/2015, Second Printing Load Carrying
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-pound (635-kilogram) cargo
and luggage capacity. You decide
to go golfing. Is there enough load
capacity to carry you, four of your
friends and all the golf bags? You
and four friends average 220
pounds (99 kilograms) each and
the golf bags weigh approximately
30 pounds (13.5 kilograms) each.
The calculation would be: 1400 -
(5 x 220) - (5 x 30) = 1400 - 1100
- 150 = 150 pounds. 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
kilograms - (5 x 99 kilograms) -
(5 x 13.5 kilograms) = 635 - 495 -
67.5 = 72.5 kilograms.
*Suppose your vehicle has a
1400-pound (635-kilogram) 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 two years. Measuring the
inside of the vehicle with the rear
seat folded down, you have room
for twelve 100-pound
(45-kilogram) bags of cement. Do
you have enough load capacity to
transport the cement to your
home? If you and your friend each
weigh 220 pounds (99 kilograms),
the calculation would be: 1400 -
(2 x 220) - (12 x 100) = 1400 - 440
- 1200 = - 240 pounds. No, you do
not have enough cargo capacity
to carry that much weight. In
metric units, the calculation would

TOWING A TRAILER
WARNINGS
Do not exceed the Gross
Vehicle Weight Rating or the
Gross Axle Weight Rating
specified on the certification label. Towing trailers beyond the
maximum recommended
gross trailer weight exceeds the
limit of the vehicle and could
result in engine damage,
transmission damage, structural
damage, loss of vehicle control,
vehicle rollover and personal
injury. Your vehicle may have electrical
items, for example fuses or relays,
related to towing. See Fuses
(page 127).
Your vehicle's load capacity
designation is by weight, not by
volume, so you cannot necessarily
use all available space when
loading your vehicle.
Towing a trailer places an extra
load on your vehicle's engine,
transmission, axle, brakes, tires
and suspension. Inspect these
components periodically during,
and after, any towing operation. 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.
Additional information regarding
correct trailer loading and setting
your vehicle up for towing is
located in another chapter of this
Owner's Manual. See
Load Limit
(page 93). You can also find the
information in the RV & Trailer
Towing Guide. See an authorized
dealer.

TRAILER SWAY CONTROL (If
Equipped) WARNING
Switching off trailer sway control
increases the risk of loss of vehicle
control, serious injury or death. We
do not recommend disabling this feature
except in situations where speed reduction
may be detrimental, for example
ascending a grade, and the driver has
significant trailer towing experience and
can control trailer sway to maintain safe
operation. This feature applies your vehicle's brakes
at individual wheels and, if necessary,
reduces engine power. If the trailer begins
to sway, the stability control light flashes
and a message appears in the information
display.
Action
Message
Slow your vehicle down,
then pull safely to the side
of the road and check for
correct tongue load and
trailer load distribution. See
Load Carrying
(page 93).
Trailer
sway
Reduce
speed
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
to gradually reduce vehicle speed. RECOMMENDED TOWING
WEIGHTS
Note:
Make sure to take into
consideration trailer frontal area.
Vehicles equipped with the Trailer
Tow Package or the Heavy Duty
Payload Package should not
exceed 60 ft² (5.6 m²) trailer
frontal area.
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
1,000 ft (300 m)
starting at the 1,000 ft (300 m)
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 charts.

Calculating 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
previous charts.
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 hardware.
• Driver weight.
• Passenger(s) weight.
• Payload, cargo and luggage
weight.
• Aftermarket equipment weight. This equals the maximum loaded
trailer weight for this combination.
Note:
The trailer tongue load is
considered part of the payload for
your vehicle. Reduce the total
payload by the final trailer tongue
weight.
Note: 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 1,000 mi (1,600 km).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the proper
installation and adjustment
specifications.
103
E-Series (TE4) Canada/United States of America, enUSA, Edition date: 03/2015, Second Printing Towing
•
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.
See Load limits in the Load Carrying
chapter for load specification terms found
on the tire label and Safety Compliance
label and instructions on calculating your
vehicle's load.
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Trailer Towing Connector When attaching the trailer wiring connector
to your vehicle, only use a proper fitting
connector that works with the vehicle and
trailer functions. Some seven-position
connectors may have the SAE J2863 logo,
which confirms that it is the proper wiring
connector and works correctly with your
vehicle.

Hitches
Do not use a hitch that either clamps onto
the bumper or attaches to the axle. You
must distribute the load in your trailer so
that 10-15% of the total weight of the
trailer is on the tongue.
Weight-distributing Hitches WARNING
Do not adjust a weight-distributing
hitch to any position where the rear
bumper of the vehicle is higher than
it was before attaching the trailer. Doing
so will defeat the function of the
weight-distributing hitch, which may cause
unpredictable handling, and could result
in serious personal injury. When hooking-up a trailer using a
weight-distributing hitch, always use the
following procedure:
1. Park the loaded vehicle, without the
trailer, on a level surface.
2. Measure the height to the top of your vehicle's front wheel opening on the
fender. This is H1.
3. Attach the loaded trailer to your vehicle
without the weight-distributing bars
connected.
4. Measure the height to the top of your vehicle's front wheel opening on the
fender a second time. This is H2.
104
E-Series (TE4) Canada/United States of America, enUSA, Edition date: 03/2015, Second Printing TowingE163167
5. Install and adjust the tension in the
weight-distributing bars so that the
height of your vehicle's front wheel
opening on the fender is approximately
half the way down from H2, toward H1.
6. Check that the trailer is level or slightly
nose down toward your vehicle. If not,
adjust the ball height accordingly and
repeat Steps 2-6.
When the trailer is level or slightly nose
down toward the vehicle:
• Lock the bar tension adjuster in place.
• Check that the trailer tongue securely
attaches and locks onto the hitch.
• Install safety chains, lighting, and trailer
brake controls as required by law or the
trailer manufacturer.
Safety Chains
Note: Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle
hitch.
To connect the safety chains, cross the
chains under the trailer tongue and allow
enough slack for turning tight corners. Do
not allow the chains to drag on the ground.
Trailer Brakes WARNING
Do not connect a trailer's hydraulic
brake system directly to your
vehicle's brake system. Your vehicle
may not have enough braking power and
your chances of having a collision greatly
increase. Electric brakes and manual, automatic or
surge-type trailer brakes are safe if you
install them properly and adjust them to
the manufacturer's specifications. The
trailer brakes must meet local and federal
regulations.
The rating for the tow vehicle's braking
system operation is at the gross vehicle
weight rating, not the gross combined
weight rating.
Separate functioning brake systems
are required for safe control of towed
vehicles and trailers weighing more
than 1500 pounds (680 kilograms)
when loaded.
Integrated Trailer Brake Controller (If
Equipped)
WARNING
The Ford trailer brake controller has
been verified to be compatible with
trailers having electric-actuated
drum brakes (one to four axles) and
electric-over-hydraulic brakes. It will not
activate hydraulic surge-style trailer
brakes. It is the responsibility of the
customer to ensure that the trailer brakes
are adjusted appropriately, functioning
normally and all electric connections are
properly made. Failure to do so may result
in loss of vehicle control, crash or serious
injury. 105
