brake FORD SUPER DUTY 2013 3.G Service Manual

PRINCIPLES OF OPERATION
The traction control system helps avoid drive wheel spin and loss of
traction.
If your vehicle begins to slide, the system applies the brakes to individual
wheels and, when needed, reduces engine power at the same time. If the
wheels spin when accelerating on slippery or loose surfaces, the system
reduces engine power in order to increase traction.
USING TRACTION CONTROL
(Dual rear wheel vehicles only)
In certain situations (for example, stuck in snow or mud), turning the
traction control off may be beneficial as this allows the wheels to spin
with full engine power.
Turn off the traction control system by pressing the
stability control button located on the instrument
panel.
If the system cannot be turned off, see theMyKey®chapter for more
information.
If traction control is on when your vehicle is put into four-wheel drive
mode (if equipped), the traction control system will be automatically
disabled. Traction control operation will resume when your vehicle is
placed back into two-wheel drive mode.

Hill descent control (if equipped)
Hill descent control allows the driver to set and maintain vehicle speed
while descending steep grades in various surface conditions.
WARNING:Hill descent control cannot control descent in all
surface conditions and circumstances, such as ice or extremely
steep grades. Hill descent control is a driver assist system and cannot
substitute for good judgment by the driver. Failure to do so may result
in loss of vehicle control, crash or serious injury.
Hill descent control can maintain vehicle speeds on downhill grades
between 2 mph (3 km/h) and 12 mph (20 km/h). Above 20 mph
(32 km/h), the system remains armed, but descent speed cannot be set
or maintained.
WARNING:Hill descent control does not provide hill hold at
zero mph (0 km/h). When stopped, the parking brake must be
applied and/or the vehicle must be placed in P (Park) or it may roll
away.
Hill descent control requires a cooling down interval after a period of
sustained use. The amount of time that the feature can remain active
before cooling varies with conditions. The system will provide a warning
in the message center and a chime will sound when the system is about
to disengage for cooling. At this time, manually apply the brakes as
needed to maintain descent speed.
Enabling hill descent control and setting the descent speed
1. Press and release the hill descent button located on
the instrument panel. A light in the cluster will
illuminate and chime will sound when this feature is
activated.
2. To increase descent speed, press the accelerator pedal until the
desired speed is reached. To decrease descent speed, press the brake
pedal until the desired speed is reached.

SENSING SYSTEM (IF EQUIPPED)
WARNING:To help avoid personal injury, please read and
understand the limitations of the system as contained in this
section. Sensing is only an aid for some (generally large and fixed)
objects when moving in reverse on a flat surface at parking speeds.
Traffic control systems, inclement weather, air brakes, and external
motors and fans may also affect the function of the sensing system; this
may include reduced performance or a false activation.
WARNING:To help avoid personal injury, always use caution
when in R (Reverse) and when using the sensing system.
WARNING:This system is not designed to prevent contact with
small or moving objects. The system is designed to provide a
warning to assist the driver in detecting large stationary objects to
avoid damaging the vehicle. The system may not detect smaller objects,
particularly those close to the ground.
WARNING:Certain add-on devices such as large trailer hitches,
bike or surfboard racks and any device that may block the normal
detection zone of the system, may create false beeps.
Note:Keep the sensors (located on the bumper/fascia) free from snow, ice
and large accumulations of dirt. If the sensors are covered, the system’s
accuracy can be affected. Do not clean the sensors with sharp objects.
Note:If your vehicle sustains damage to the bumper/fascia, leaving it
misaligned or bent, the sensing zone may be altered causing inaccurate
measurement of obstacles or false alarms.
Note:If your vehicle is equipped with MyKey®, it is possible to prevent
turning the sensing system off. Refer to theMyKey®chapter.
Note:If your vehicle is equipped with a fully integrated electronic trailer
brake controller (TBC) and a trailer with electric trailer brakes is
connected to your vehicle, the RSS will be disabled. When the vehicle is
shifted into reverse, the message center display will remain in the Rear
Park Aid Off selection. For more information on the TBC, refer to the
Towingchapter.

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 theRV and Trailer Towing Guideprovided 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.

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 the 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
Fuseschapter.
Your vehicle’s load capacity is designated by weight, not by volume, so
you cannot necessarily use all available space when loading a vehicle.
Towing a trailer places an additional 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 the vehicle when driving:
•Load the heaviest items closest to the trailer floor.
•Load the heaviest items so they are 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 the 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 proper trailer loading and setting your vehicle up
for towing is noted underLoad limitin theLoad Carryingchapter and
in theRV & Trailer Towing Guide,available at your authorized dealer.
TRAILER SWAY CONTROL (IF EQUIPPED)
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
activate multiple times, gradually reducing vehicle speed.
Towing249

Owners Guide gf, 1st Printing
USA(fus)

This feature applies the vehicle brakes at individual wheels and, if
necessary, reduces engine power. If the trailer begins to sway, the
stability control light flashes and the messageTRAILER SWAY
REDUCE SPEEDappears in the information display. The first thing to
do is slow the vehicle down, then pull safely to the side of the road and
check for proper tongue load and trailer load distribution. See theLoad
Carryingchapter for specific loading information.
RECOMMENDED TOWING WEIGHTS
Note:Do not exceed a trailer weight of 5000 pounds (2268 kilograms)
when towing with, or by, bumper only.
Note:Trailer frontal area is the total area in square feet (meters) that a
moving vehicle and trailer are exposed to air resistance. The following
trailer frontal area limitations should be considered in selecting a trailer
based on your vehicle configuration:
•60 feet
2(5.57 meters2) for conventional, 5th wheel and gooseneck
trailers.
Note:Exceeding these limitations may significantly reduce the
performance of your towing vehicle. Selecting a trailer with a low
aerodynamic drag and rounded front design will help 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 the vehicle’s electrical system may not include the
wiring connector needed to activate electric trailer brakes.
Your vehicle may tow a class I, II, III and IV trailer or fifth-wheel trailer
provided the maximum trailer weight is less than or equal to the
maximum trailer weight listed for your engine and rear axle ratio on the
following chart.
To calculate the maximum loaded trailer weight for your vehicle:
1. Start with GCWR 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 (e.g. draw bar, ball, locks, weight
distributing, etc.)

Hitches
WARNING:ON PICK-UP TRUCKS, the trailer hitch provided on
this vehicle enhances collision protection for the fuel system. DO
NOT REMOVE!
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% for
conventional towing or 15–25% for fifth-wheel towing 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 the vehicle front wheel opening on
the fender, this is H1.
3. Securely attach the loaded trailer to the vehicle without the
weight-distributing bars connected.
4. Measure the height to the top of the vehicle front wheel opening on
the fender a second time, this is H2.
5. Install and adjust the tension in the weight-distributing bars so that
the height of the vehicle’s front wheel opening on the fender is
approximately halfway between H1 and H2.
6. Check that the trailer is level or slightly nose down toward the
vehicle. If not, adjust the ball height accordingly and repeat
Steps 1–6.
7. Lock bar tension adjuster in place.
8. Check that the trailer tongue is securely attached and locked to the
hitch.
9. 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 trailer’s safety chains to the frame or hook retainers
of the vehicle hitch.
To connect the trailer’s 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 installed properly and adjusted to the manufacturer’s specifications. The
trailer brakes must meet local and Federal regulations.
The braking system of the tow vehicle is rated for operation at
the GVWR not GCWR.
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 TBC has been verified to be compatible
with trailers having electric-actuated drum brakes (one to four
axles) and some electric-over-hydraulic (EOH) 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.
When used properly, the TBC assists in smooth and effective trailer
braking by powering the trailer’s electric or EOH brakes with a
proportional output based on the towing vehicle’s brake pressure.
Your vehicle may be equipped with a fully integrated electronic trailer
brake controller (TBC). When used properly, the TBC helps ensure smooth
and effective trailer braking by powering the trailer’s electric brakes with a
proportional output based on the towing vehicle’s brake pressure.
