EMISSION CONTROL SYSTEM
- DIESEL
Oxidation Catalytic Converter and
Diesel Particulate Filter System (If
Equipped) WARNING
The normal operating temperature
of the exhaust system is very high.
Never work around or attempt to
repair any part of the exhaust system until
it has cooled. Use special care when
working around the diesel oxidation
catalytic converter or the diesel particulate
filter. The diesel oxidation catalytic
converter and the diesel particulate filter
heat up to very high temperatures after
only a short period of engine operation and
remain hot after you switch the engine off. Your vehicle has a diesel particulate filter.
The diesel particulate filter is an inline filter
in the exhaust system that reduces carbon
emissions by trapping exhaust particles
before they reach the tailpipe. The diesel
particulate filter looks similar to a
traditional exhaust catalyst and is part of
the exhaust system under your vehicle. The
filter couples to a diesel oxidation catalyst
that reduces the amount of harmful
exhaust emitted from the tailpipe. As soot
gathers in the system, it begins to restrict
the filter. The system must periodically
clean the soot that gathers inside the filter.
This is carried out in two ways, passive
regeneration and active regeneration. Both
methods occur automatically and require
no actions from the driver. During either
one of these regeneration methods,
although you may notice a change in
exhaust tone. At certain times, the
information display shows various
messages related to the diesel particulate
filter. See
Information Messages (page
128). Diesel Particulate Filter Maintenance
You must properly maintain your vehicle's
diesel particulate filter in order for it to
function properly.
Do not disregard maintenance messages
that appear in the information display.
Failure to follow the instructions of an
information message may degrade vehicle
performance and could lead to engine
damage that may not be covered by the
vehicle Warranty.
Failure to perform active or operator
commanded regeneration when instructed
could result in a clogged diesel particulate
filter. If the diesel particulate filter fills
beyond the regeneration threshold, your
vehicle disables the ability for active and
operator commanded regeneration. This
could result in irreversible damage to the
diesel particulate filter requiring
replacement that may not be covered by
the vehicle Warranty.
Passive Regeneration
In passive regeneration, the exhaust
system temperature and constituents
automatically clean the filter by oxidizing
the soot. Cleaning automatically occurs
during normal vehicle operating conditions
due to driving patterns.
Active Regeneration
Once the diesel particulate filter is full of
exhaust particles, the engine control
module commands the exhaust system to
clean the filter through active regeneration.
Active regeneration requires the engine
computer to raise the exhaust temperature
to eliminate the particles. During cleaning,
the particles convert to harmless gasses.
Once cleaned the diesel particulate filter
continues trapping exhaust particles.

9. Start your vehicle.
Perform Steps 4 through 8 in reverse order,
making sure to engage the hinge pivots
between the upper and lower halves of the
shroud. Keep slight pressure in the forward
direction as you rotate the halves together.
If Your Vehicle Gets Stuck In Mud
or Snow
Note:
Do not rock your vehicle if the engine
is not at normal operating temperature or
damage to the transmission may occur.
Note: Do not rock your vehicle for more
than a minute or damage to the
transmission and tires may occur, or the
engine may overheat.
If your vehicle is stuck in mud or snow, you
may rock it out by shifting between forward
and reverse gears, stopping between shifts
in a steady pattern. Press lightly on the
accelerator in each gear. POWER TAKE-OFF WARNING
Use of auxiliary equipment that
exceeds the maximum Power
Take-Off (PTO) load specified in the
Ford Truck Body Builders Layout Book can
adversely affect the performance of the
powertrain system. Refer to the Body
Builders Layout Book for instructions about
the appropriate installation of additional
equipment. Auxiliary equipment called power take-off,
or PTO, is often added to the engine or
transmission to operate utility equipment.
Examples include a wheel-lift for tow
trucks, cranes, tools for construction or tire
service, and pumping fluids. PTO
applications draw auxiliary horsepower
from the powertrain, often while the
vehicle is stationary. In this condition, there
is limited cooling air flow through the
radiator and around the vehicle that
normally occurs when a vehicle is moving.
The aftermarket PTO system installer,
having the most knowledge of the final
application, is responsible for determining
whether additional chassis heat protection
or powertrain cooling is required, and
alerting the user to the safe and proper
operation.
Ford Super Duty Vehicles are approved for
use as a stationary (including split shaft
capability) or mobile power source, within
limits and operating guidelines detailed in
the Ford Truck Body Builders Layout Book,
found at www.fleet.ford.com/truckbbas,
and through the Ford Truck Body Builders
Advisory Service.

If Shift Delayed Pull Forward appears in
the information display, transfer case gear
tooth blockage is present. To alleviate this
condition, place the transmission in a
forward gear, move the vehicle forward
approximately
5 ft (1.5 m), and shift the
transmission back to neutral to allow the
transfer case to complete the range shift.
How Your Vehicle Differs From
Other Vehicles WARNING
Vehicles with a higher center of
gravity (utility and four-wheel drive
vehicles) handle differently than
vehicles with a lower center of gravity
(passenger cars). Avoid sharp turns,
excessive speed and abrupt steering in
these vehicles. Failure to drive cautiously
increases the risk of losing control of your
vehicle, vehicle rollover, personal injury and
death. Truck and utility vehicles can differ from
some other vehicles. Your vehicle may be
higher to allow it to travel over rough
terrain without getting hung up or
damaging underbody components.
The differences that make your vehicle so
versatile also make it handle differently
than an ordinary passenger car.
Maintain steering wheel control at all
times, especially in rough terrain. Since
sudden changes in terrain can result in
abrupt steering wheel motion, make sure
you grip the steering wheel from the
outside. Do not grip the spokes.
Drive cautiously to avoid vehicle damage
from concealed objects such as rocks and
stumps. You should either know the terrain or
examine maps of the area before driving.
Map out your route before driving in the
area. To maintain steering and braking
control of your vehicle, you must have all
four wheels on the ground and they must
be rolling, not sliding or spinning.
Driving Off-Road With Truck and
Utility Vehicles
Note:
On some models, the initial shift from
two-wheel drive to four-wheel drive while
the vehicle is moving can cause some
momentary clunk and ratcheting sounds.
This is the front drivetrain coming up to
speed and the automatic locking hubs
engaging and is not cause for concern.
Note: Your vehicle may be equipped with
a front air dam that can become damaged
(due to reduced ground clearance) when
taking your vehicle off-road. This air dam
can be taken off by removing 15 bolts.
Four-wheel drive vehicles are specially
equipped for driving on sand, snow, mud
and rough terrain and have operating
characteristics that are somewhat
different from conventional vehicles, both
on and off the road.
Power is supplied to all four wheels
through a transfer case. On four-wheel
drive vehicles, the transfer case allows you
to select 4WD when necessary.
Information on transfer case operation and
shifting procedures can be found in this
chapter. Information on transfer case
maintenance can be found in the
Maintenance chapter. You should become
thoroughly familiar with this information
before you operate your vehicle.
Four-wheel drive (when you select a 4WD
mode) uses all four wheels to power the
vehicle. This increases traction, enabling
you to drive over terrain and road
conditions that a conventional two-wheel
drive vehicle cannot.

Super Duty (TFE) Canada/United States of America, enUSA, First Printing Four-Wheel Drive
(If Equipped)

The system uses radar sensors that are
located inside the tail lamp on each side
of your vehicle. Any dirt, mud and snow in
front of the sensors or driving in heavy rain
can cause system degradation. Also, other
types of obstructions in front of the sensor
can cause system degradation. This is
referred to as a
‘blocked ’ condition.
Note: Do not apply bumper stickers and/or
repair compound to these areas, this can
cause degraded system performance.
If the system detects a degraded
performance condition, a message warning
appears in the display screen. The alert
indicators remain ON and the system will
no longer provides any warnings. You can
clear the warning but the alert indicators
remain illuminated.
A "blocked" condition can be cleared in
two ways:
• After the blockage in front of the
sensors is removed or the
rainfall/snowfall rate decreases or
stops, drive for a few minutes in traffic
to allow the sensors to detect passing
vehicles.
• By cycling the ignition from ON to OFF
and then back ON.
Note: If your vehicle has a tow bar with a
factory equipped trailer tow module and it
is towing a trailer, the sensors will
automatically turn the Blind Spot
Information System off. If your vehicle has
a tow bar but no factory equipped trailer
tow module, it is recommended to turn the
Blind Spot Information System off
manually. Operating the Blind Spot
Information System without the Blind Spot
Trailer Tow package and a trailer attached
will cause poor system performance. Blind Spot Information System
with Trailer Tow (If Equipped)
The Blind Spot Information System with
Trailer Tow is designed to aid you in
detecting vehicles that may have entered
the detection area zone (A). The detection
area is on both sides of your vehicle and
trailer, extending rearward from the
exterior mirrors to the end of your trailer.
When a trailer is attached and the
customer has set up a Blind Spot Trailer,
the Blind Spot Information System with
Trailer Tow becomes active when driving
forward above
6 mph (10 km/h). See
Trailer Reversing Aids (page 269).
The Blind Spot Information System with
Trailer Tow can be turned off in the
instrument cluster. If the Blind Spot
Information System is turned off, then the
Blind Spot Information System with Trailer
Tow automatically turns off.

Note:
It is recommended that you turn the
collision warning system off if a snow plow
or similar object is installed in such a way
that it may block the radar sensor. Your
vehicle will remember the selected setting
across key cycles.
Note: When possible, the manufacturer
recommends using the highest sensitivity
setting. If warnings are too frequent, you can
reduce your system's sensitivity. Reduced
sensitivity causes fewer and later system
warnings. See General Information (page
111). Blocked Sensors If a blocked sensor message appears in the
information display, dirt, water, or an object
is blocking the sensor. The sensor is
located behind a cover near the driver side
of the lower grille. If anything blocks the
sensor, your vehicle cannot see through
the sensor, and the collision warning
system will not work. Possible causes for
the blocked sensor message and corrective
actions are listed below.

Procedure for Setting Trailer Brake
Controller Effort
Choose either the electric option for trailers
with electromagnetic drum brakes, or the
electric over hydraulic option for trailers
with these brake systems.
Trailer Brake Effort Setting
The trailer brake controller allows the user
to customize how aggressively the trailer
brakes engage. The default value is the low
setting and is the recommended setting
for most trailers. If your trailer's brakes
require more initial voltage, or if you prefer
more aggressive trailer braking, then select
either the medium or the high setting.
Procedure for Setting Trailer Brake
Controller Mode
Choose the low, medium or high setting
for the required initial trailer brake output.
Procedure for Adjusting Gain
Note:
Only perform this procedure in a
traffic-free environment at speeds of
approximately 20-25 mph (30-40 km/h).
The gain setting adjusts 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.
1. Make sure the trailer brakes are in good
working condition, functioning normally
and properly adjusted. See your trailer
dealer if necessary.
2. Hook up the trailer and make the electrical connections according to the
trailer manufacturer's instructions. 3. When you plug in a trailer with electric
or electric-over-hydraulic brakes, a
confirmation message appears in the
information display.
4. Use the gain adjustment (+ and -) buttons to increase or decrease the
gain setting to the desired starting
point. A gain setting of 6.0 is a good
starting point for heavier loads.
5. 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 control lever
completely.
6. If the trailer wheels lock up, indicated by squealing tires, reduce the gain
setting. If the trailer wheels turn freely,
increase the gain setting. Repeat Steps
5 and 6 until the gain setting is at a
point just below trailer wheel lock-up.
If towing a heavier trailer, trailer wheel
lock-up may not be attainable even
with the maximum gain setting of 10.
Information Display Warning Messages
Note: An authorized dealer can diagnose
the trailer brake controller to determine
exactly which trailer fault has occurred.
However, your Ford warranty does not cover
this diagnosis if the fault is with the trailer.
TRAILER BRAKE MODULE FAULT
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 with
degraded performance.
WIRING FAULT ON TRAILER
Displays when there is a short circuit on
the electric brake output wire.

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.
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.
