tow FORD TRANSIT 2017 5.G Service Manual

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 your vehicle
has covered at least 1,000 mi
(1,600 km). See Breaking-In (page
180).
• Consult your local motor vehicle laws
for towing a trailer.
• See the instructions included with
towing accessories for the correct
installation and adjustment
specifications.
• Service your vehicle more frequently if
you tow a trailer. See
Scheduled
Maintenance (page 427).
• If you use a rental trailer, follow the
instructions the rental agency gives
you.
Refer to
Load Carrying for load
specification terms found on the tire label,
Safety Compliance label and instructions
on calculating your vehicle's maximum
load. See
Load Limit (page 164).
Remember to account for the trailer
tongue weight as part of your vehicle load
when calculating the total vehicle weight.
Trailer Towing Connector
(If Equipped) Your vehicle is fitted with both a 7 pin and
4 pin trailer wiring connector.

When attaching the trailer wiring connector
to your vehicle, only use a correctly 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 correct wiring
connector and works correctly with your
vehicle.

Tow Hitch WARNING
Do not exceed the lesser of the
vehicle or trailer hitch rating. Rating
will vary depending on vehicle
equipment. Vehicle stability and handling
can be impaired if vehicle or trailer hitch is
over-loaded. Do not cut, drill, weld or
modify trailer hitches. Modifying trailer
hitches can reduce hitch rating. Serious
injury or death can result from over-loaded
vehicle or trailer hitch. Do not use a tow hitch that either clamps
on to the bumper or attaches to the axle.
You must distribute the load in your trailer
so that between 10% and 15% of the total
weight of the trailer is on the tongue. Weight Distributing Hitches
A weight distribution hitch is not
recommended for use with your vehicle.
Safety Chains WARNING
Do not attach safety chains to the
bumper.
Always connect the safety chains to the
frame or hook retainers of your vehicle's
tow 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 (If Equipped)
WARNING
Do not connect trailer hydraulic
brake systems directly to the vehicle
brake system. Your vehicle may not
have enough braking power and your
chances of having a crash greatly increase. Electric, manual, automatic or surge-type
trailer brakes are safe if you install them
correctly and adjust them to the
manufacturer's specifications. 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
1,500 lb
(680 kg) when loaded.

Integrated Trailer Brake Controller
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
turn on the hydraulic surge-style trailer
brakes. It is the responsibility of the
customer to make sure that the trailer
brakes are adjusted appropriately,
functioning normally and all electric
connections are correctly made. Failure to
do so may result in loss of vehicle control,
crash or serious injury. Manual control lever.
A
Gain adjustment buttons.
B When used correctly, the trailer brake
controller assists in smooth and effective
trailer braking by powering the trailer
’s
electric or electric-over-hydraulic brakes
with a proportional output based on the
towing vehicle ’s brake pressure
Slide the manual control lever to the left
to turn on the trailer's electric brakes. They
work independently of the tow vehicle's
braking system. See Procedure for
adjusting the gain setting for
instructions on correct use of this feature.
If you use the manual control while the
brake is also applied, the greater of the two
inputs determines the power sent to the
trailer brakes.
1. Press the + and - buttons to adjust the
brake controller's power output to the
trailer brakes in 0.5 increments. You
can increase the gain setting to 10
(maximum trailer braking) or decrease
it to zero (no trailer braking). Pressing
and holding a button raises or lowers
the setting continuously.
The gain setting displays in the
information display as: Message
Trailer Brake
Gain:
Note: Using the manual control lever
illuminates the trailer's brake lamps and
your vehicle's brake lamps, except the
center high-mounted brake lamp, if you
make the correct electrical connection to
the trailer.

and when adjusting the gain setting. This also displays if you
use the manual control lever or make gain adjustments with
no trailer connected.
Trailer Brake
Gain:
No Trailer
Displays when you press your vehicle's brake pedal, or upon
use of the manual control lever. Bar indicators illuminate in
the information display to indicate the amount of power going
to the trailer brakes relative to the brake pedal or manual
control input. One bar indicates the least amount of output;
six bars indicate maximum output.
Trailer Brake
Gain:
Output:
Displays when the system senses a correct trailer wiring
connection during a given ignition cycle. For example a trailer
with electric trailer brakes.
Trailer Connected
Displays when the system senses a trailer connection and
then a disconnection, either intentional or unintentional,
during a given ignition cycle, this is accompanied by a single
audible tone. It also displays if a vehicle or trailer-wiring fault
occurs causing the trailer to appear disconnected. This
message can also display if you use the manual control lever
without a trailer connected.
Trailer Disconnected
Procedure for Adjusting the Gain Setting
The gain setting sets the trailer brake
controller for the specific towing condition.
You should change the setting as towing
conditions change. Changes to towing
conditions include trailer load, vehicle load,
road conditions and weather.
The gain should be set to provide the
maximum trailer braking assistance while
making sure the trailer wheels do not lock
when using the brakes. Locked trailer
wheels may lead to trailer instability.
Note: Only carry out this procedure 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 correctly 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. Use the gain adjustment + and -
buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of six is a good
starting point for heavier loads.
4. 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 slide
the manual control lever completely.
175
Transit (TTH) Canada/United States of America, HK3J 19A321 AA enUSA, Edition date: 04/2016, First Printing Towing

5. If the trailer wheels lock, indicated by
squealing tires, reduce the gain setting.
If the trailer wheels turn freely, increase
the gain setting. Repeat steps four and
five until the gain setting is at a point just below trailer wheel lock. If towing
a heavier trailer, trailer wheel lock may
not be attainable even with the
maximum gain setting of 10.
System Warning Messages Action and Description
Message
Displays in response to faults sensed by the trailer brake
controller, accompanied by a single tone. If this message
appears, contact an authorized dealer as soon as possible
for diagnosis and repair. The controller may still function, but
performance may be degraded.
Trailer Brake Module
Fault
Displays when there is a short circuit on the electric brake
output wire. If the message displays, accompanied by a single
tone, with no trailer connected, the problem is with your
vehicle wiring between the trailer brake controller and the 7-
pin connector. If the message only displays with a trailer
connected, the problem is with the trailer wiring. Consult a
trailer dealer for assistance. This can be a short to ground,
for example a chaffed wire, short to voltage, for example a
pulled pin on trailer emergency breakaway battery or the
trailer brakes may be drawing too much current.
Wiring Fault on Trailer
Note: An authorized dealer can diagnose the trailer brake controller to determine exactly
which trailer fault has occurred. However, the Ford Warranty does not cover this diagnosis
if the fault is with the trailer.
Points to Remember
• Do not attempt removal of the trailer
brake controller without consulting the
Workshop Manual. Damage to the unit
may result.
• Adjust gain setting before using the
trailer brake controller for the first time.
• Adjust gain setting, using the procedure
above, whenever road, weather and
trailer or vehicle loading conditions
change from when the gain was initially
set. •
Only use the manual control lever for
correct adjustment of the gain during
trailer setup. Misuse, such as
application during trailer sway, could
cause instability of trailer or tow
vehicle.
• Avoid towing in adverse weather
conditions. The trailer brake controller
does not provide anti-lock control of
the trailer wheels. Trailer wheels can
lock up on slippery surfaces, resulting
in instability of trailer or tow vehicle.
176
Transit (TTH) Canada/United States of America, HK3J 19A321 AA enUSA, Edition date: 04/2016, First Printing Towing

•
The trailer brake controller is fitted with
a feature that reduces output at vehicle
speeds below 11 mph (18 km/h) so
trailer and vehicle braking is not jerky
or harsh. This feature is only available
when applying the brakes using your
vehicle's brake pedal, not the
controller.
• The controller interacts with the brake
control system and powertrain control
system of your vehicle to provide the
best performance on different road
conditions.
• Your vehicle's brake system and the
trailer brake system work
independently of each other. Changing
the gain setting on the controller does
not affect the operation of your
vehicle's brake system whether you
attach a trailer or not.
• When you switch the engine off, the
controller output is disabled and the
display and module shut down. The
controller module and display turn on
when you switch the ignition on.
• The trailer brake controller is only a
factory-installed or dealer-installed
item. Ford is not responsible for
warranty or performance of the
controller due to misuse or customer
installation.
Trailer Lamps WARNING
Never connect any trailer lamp wiring
to the vehicle's tail lamp wiring; this
may damage the electrical system
resulting in fire. Contact an authorized
dealer as soon as possible for assistance
in correct trailer tow wiring installation.
Additional electrical equipment may be
required. Trailer lamps are required on most towed
vehicles. Make sure all running lamps,
brake lamps, turn signals and hazard
warning lamps are working.
Before Towing a Trailer
Practice turning, stopping and backing up
to get the feel of your vehicle-trailer
combination before starting on a trip.
When turning, make wider turns so the
trailer wheels clear curbs and other
obstacles.
When Towing a Trailer
•
Do not drive faster than
70 mph
(113 km/h) until you drive your vehicle
at least 495 mi (800 km). See
Breaking-In (page 180).
• Do not make full-throttle starts.
• Check the tow hitch, electrical
connections and trailer wheel lug nuts
thoroughly after you have traveled
50 mi (80 km)
.
• When stopped in congested or heavy
traffic during hot weather, place the
gearshift in position park (
P) to aid
engine and transmission cooling and
to help A/C performance.
• Turn off the speed control with heavy
loads or on hilly terrain. The speed
control may turn off automatically
when you are towing on long, steep
grades.
• Shift to a lower gear when driving down
a long or steep hill. Do not apply the
brakes continuously, as they may
overheat and become less effective.
• If the transmission is fitted with a
Grade Assist, Tow/Haul
feature, use
this feature when towing. This provides
engine braking and helps eliminate
excessive transmission shifting for
optimum fuel economy and
transmission cooling.
177
Transit (TTH) Canada/United States of America, HK3J 19A321 AA enUSA, Edition date: 04/2016, First Printing Towing

•
If your vehicle is fitted with
AdvanceTrac with roll stability control
(RSC), this system may turn on during
typical cornering maneuvers with a
heavily loaded trailer. This is normal.
Turning the corner at a slower speed
while towing may reduce this tendency.
• If you are towing a trailer frequently in
hot weather, hilly conditions, at the
gross combined weight rating (or any
combination of these factors), consider
refilling your vehicle's rear axle with
synthetic gear lubricant (if the axle is
not already filled with it). See
Capacities and Specifications (page
281).
• Allow more distance for stopping with
a trailer attached. Anticipate stops and
brake gradually.
• Avoid parking on a grade. However, if
you must park on a grade:
•Turn the steering wheel to point
your vehicle tires away from traffic
flow.
• Set your vehicle parking brake.
• Place the automatic transmission
in position park (
P).
• Place wheel chocks in front of and
at the back of the trailer wheels.
(Trailer wheel chocks are not
included with your vehicle.)
Launching or Retrieving a Boat or
Personal Water Craft (PWC)
When backing down a ramp during boat
launching or retrieval:
• Do not allow the static water level to
rise above the bottom edge of the rear
bumper.
• Do not allow waves to break higher
than
6 in (15 cm) above the bottom
edge of the rear bumper.
Note: Disconnect the wiring to the trailer
before backing the trailer into the water. Note:
Reconnect the wiring to the trailer
after the trailer is removed from the water.
Exceeding these limits may allow water to
enter vehicle components:
• Causing internal damage to the
components.
• Affecting driveability, emissions, and
reliability.
Replace the rear axle lubricant anytime
the rear axle has been submerged in water.
Water may have contaminated the rear
axle lubricant, which is not normally
checked or changed unless a leak is
suspected or other axle repair is required.
TOWING THE VEHICLE ON
FOUR WHEELS
Emergency Towing WARNING
If your vehicle has a steering wheel
lock make sure the ignition is in the
accessory or on position when being
towed. You can flat-tow (all wheels on the
ground, regardless of the powertrain or
transmission configuration) your disabled
vehicle (without access to wheel dollies
or vehicle transport trailer) under the
following conditions:
•
Your vehicle is facing forward so you
tow it in a forward direction.
• You shift into Neutral (N). If you cannot
shift into Neutral (N), you may need to
override the transmission. See
Transmission
(page 141).
• Maximum speed is 35 mph (56 km/h).
• Maximum distance is
50 mi (80 km).

Recreational Towing
Note:
Put your climate control system in
recirculated air mode to prevent exhaust
fumes from entering the vehicle. See
Climate Control (page 95).
Follow these guidelines if you have a need
for recreational (RV) towing. An example
of recreational towing would be towing
your vehicle behind a motorhome. These
guidelines are to make sure you do not
damage the transmission during towing.
Do not tow your vehicle with any wheels
on the ground, as vehicle or transmission
damage may occur. It is recommended to
tow your vehicle with all four wheels off
the ground, for example when using a
vehicle transport trailer. Otherwise, you
cannot tow your vehicle.

If you need to have your vehicle towed,
contact a professional towing service or,
if you are a member of a roadside
assistance program, your roadside
assistance service provider.
We recommend the use of a wheel lift and
dollies or flatbed equipment to tow your
vehicle. Do not tow with a slingbelt. Ford
Motor Company has not approved a
slingbelt towing procedure. Vehicle
damage may occur if towed incorrectly, or
by any other means.
Ford Motor Company produces a towing
manual for all authorized tow truck
operators. Have your tow truck operator
refer to this manual for proper hook-up
and towing procedures for your vehicle.
It is acceptable to have your front-wheel
drive vehicle towed from the front if using
proper wheel lift equipment to raise the
front wheels off the ground. When towing
in this manner, the rear wheels can remain
on the ground.
Front-wheel drive vehicles must have the
front wheels placed on a tow dolly when
towing your vehicle from the rear using
wheel lift equipment. This prevents
damage to the transmission.
Towing an all-wheel or four-wheel drive
vehicle requires that all wheels be off the
ground, such as using a wheel lift and
dollies or flatbed equipment. This prevents
damage to the transmission, all-wheel or
four-wheel drive system and vehicle.
