EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws.
Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light.
Tampering With a Noise Control
System
Federal laws prohibit the following acts:
• Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.
115
Engine Emission Control

• Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note:Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note:If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg) GVWR.
CATALYTIC CONVERTER
WARNING: Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire.
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 catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off.
WARNING: Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle (page 190).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Have the items listed in scheduled
maintenance information performed
according to the specified schedule.
Note:Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
such non-Ford parts should be equivalent
to genuine Ford Motor Company parts in
performance and durability.

Engine Emission Control

ECONOMICAL DRIVING
Your fuel economy is affected by several
things, such as how you drive, the
conditions you drive under, and how you
maintain your vehicle.
You may improve your fuel economy by
keeping these things in mind:
• Accelerate and slow down in a smooth,
moderate fashion.
• Drive at steady speeds without
stopping.
• Anticipate stops; slowing down may
eliminate the need to stop.
• Close the windows for high-speed
driving.
• Drive at reasonable speeds. Traveling
at 55 mph (90 km/h) uses 15% less
fuel than traveling at 65 mph
(105 km/h).
• Keep the tires properly inflated and use
only the recommended size.
• Use the recommended engine oil.
• Perform all regularly scheduled
maintenance.
Avoid these actions; they reduce your fuel
economy:
• Sudden accelerations or hard
accelerations.
• Warm up your vehicle on cold
mornings.
• Use the air conditioner.
• Use the speed control in hilly terrain.
• Rest your foot on the brake pedal while
driving.
• Carry unnecessary weight.
Approximately 1 mpg [0.4 km/L] is lost
for every 400 lb (180 kg) of weight
carried.
• Driving with the wheels out of
alignment.Conditions
• Adding certain accessories to your
vehicle may reduce fuel economy. For
example bug deflectors, rollbars, light
bars, running boards, ski racks or
luggage racks.
• Using fuel blended with alcohol may
lower fuel economy.
• Fuel economy may decrease with lower
temperatures during the first 5–10 mi
(12–16 km) of driving.
• Driving on flat terrain offers improved
fuel economy as compared to driving
on hilly terrain.
• Transmissions give their best fuel
economy when operated in the top
cruise gear and with steady pressure
on the gas pedal.
COLD WEATHER
PRECAUTIONS
Note:Idling in cold weather does not heat
the engine to its normal operating
temperature. Long periods of idling,
especially in cold weather, can cause a
buildup of deposits which can cause engine
damage.
Changing to a lighter grade engine oil also
makes starting easier under these
conditions. Refer to Engine oil
specifications. See Engine Oil Capacity
and Specification (page 292).
Diesel fuel is adjusted seasonally for cold
temperatures. Diesel fuel which has not
been properly formulated for the ambient
conditions may gel which can clog the fuel
filters. One indication that the fuel filter(s)
may be clogged is if the engine starts, stalls
after a short time, and then does not
restart. If you have been using biodiesel,
you may need to use a fuel with lower
biodiesel content, try another brand, or
discontinue using biodiesel. Do not use
184
Driving Hints

alcohol based additives to correct fuel
gelling. This may result in damage to the
fuel injectors and system. Use the proper
anti-gel and performance improvement
product. See Engine Oil Capacity and
Specification (page 292).
Your vehicle is equipped with a fuel and
water separator that recirculates fuel from
the engine to help prevent fuel filter
clogging. To avoid engine fuel starvation
during cold weather operation of 32°F
(0°C) or below, we recommended that
the fuel level in your tank should not drop
below 1⁄4 full. This helps prevent air from
entering the fuel system and stalling the
engine.
Your vehicle is equipped with a selective
catalyst reduction system that uses Diesel
Exhaust Fluid (DEF) to operate properly.
You need to replenish your vehicle’s DEF
at certain intervals. When filling your
vehicle’s DEF tank in cold weather, you
must take special care to prevent damage
to the tank. See Selective Catalytic
Reductant System (page 118).
In cold weather below 32°F (0°C), the
engine may slowly increase to a higher idle
speed if left idling in park (P) or neutral
(N).
If you operate your vehicle in a heavy
snowstorm or blowing snow conditions,
snow and ice can clog the engine air
induction. If this occurs, the engine may
experience a significant reduction in power
output. At the earliest opportunity, clear
all the snow or ice away from inside the air
filter assembly. Remove the air cleaner
cover and the pleated paper filter, leaving
the foam filter in and remove any snow or
ice. Make sure you install the foam filter
correctly in place. Remove any debris,
snow or ice on the foam filter by brushing
the surface with soft brush. Once you have
cleared all of the debris, reinstall the air
filter and assembly.Do not use water, solvents, or a hard brush
for cleaning the foam filter.
WARNING: To reduce the risk of
vehicle damage and/or personal burn
injuries do not start your engine with the
air filter removed and do not remove it
while the engine is running.
In order to operate the engine in
temperatures of 32°F (0°C) or lower, read
the following instructions:
• Make sure that the batteries are of
sufficient size and are fully charged.
Check other electrical components to
make sure they are in optimum
condition
• Use the proper coolant solution at the
concentration recommended
protecting the engine against damage
from freezing
• Try to keep the fuel tank full as much
as possible at the end of operation to
prevent condensation in the fuel
system
• Make sure you use proper cold weather
engine oil and that it is at its proper
level. Also, if necessary, make sure to
follow the engine oil and filter change
schedule found under the Special
operating conditions section listed in
the scheduled maintenance
information
• At temperatures of -9°F (-23°C) or
below, it is recommended that you use
an engine block heater to improve cold
engine starting
• If operating in arctic temperatures of
-20°F (-29°C) or lower, consult your
truck dealer for information about
special cold weather equipment and
precautions
185
Driving Hints

Avoid driving too fast during the first
1,000 mi (1,600 km). Vary your speed
frequently and change up through the
gears early. Do not labor the engine.
Drive your new vehicle at least 1,000 mi
(1,600 km) before towing a trailer. Make
sure you use the specified engine oil. See
Engine Oil Capacity and Specification
(page 292).
Do not add friction modifier compounds
or special break-in oils during the first few
thousand miles (kilometers) of operation.
These additives may prevent piston ring
seating.
DRIVING THROUGH WATER
WARNING: Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note:Driving through standing water can
cause vehicle damage.
Note:Engine damage can occur if water
enters the air filter.
Before driving through standing water,
check the depth. Never drive through water
that is higher than the bottom of the wheel
hubs.
E176913E176913
When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited. After driving through water and
as soon as it is safe to do so:
• Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
• Check that the exterior lights work.
• Turn the steering wheel to check that
the steering power assist works.
Operation in Standing Water
Ingestion of water into the diesel engine
can result in immediate and severe
damage to the engine. If driving through
water, slow down to avoid splashing water
into the intake. If the engine stalls, and you
suspect ingestion of water into the engine,
do not try to restart the engine. Consult
your dealer for service immediately.
Your fuel tank vents to the atmosphere by
valves on top of the tank and through the
fuel cap. If water reaches the top of the
tank, the valves may pull water into the
fuel tank. Water in the fuel can cause
performance issues and damage the fuel
injection system.
