2013 FORD SUPER DUTY warning

SELECTIVE CATALYTIC REDUCTION (SCR) SYSTEM
Your vehicle is equipped with a selective catalytic reduction (SCR)
system to help reduce emission levels of oxides of nitrogen from the
exhaust of the diesel engine. The system automatically injects diesel
exhaust fluid (DEF) into the exhaust system to enable proper SCR
function.
Importance of maintaining the DEF level
In order for the SCR system to operate properly, the DEF level must be
maintained. Generally, the DEF tank should be filled during the oil
change service interval. See thescheduled maintenance informationin
this supplement for more information. However, certain conditions or
driving styles, such as trailer towing or fast rates of acceleration, will
require the refilling of the DEF tank more often.
The engine control unit will monitor the amount of fluid available in the
DEF tank. Running a system check in the message center will indicate
whether the DEF level is ok or if it is less than 1/2 full. A message will
automatically be displayed in the message center when the DEF level is
low and needs to be refilled. When you see this message you should refill
your tank. See theInformation displayschapter of yourOwner’s
Manualfor information display functions. For instructions on refilling
your DEF tank, seeFilling the DEF tankin theFuel and Refueling
chapter.
DEF warning messages and vehicle operations
WARNING:Diesel Exhaust Fluid (DEF) must be refilled when
low or replaced when contaminated or the vehicle speed will be
speed limited to 50 mph (80 km/h). In these conditions, drive with
caution and refill DEF immediately. If the DEF becomes empty or
contaminated fluid is not replaced, the vehicle will become limited to
idle speed only once stopped. In these conditions, be cautious where
you stop the vehicle because you may not be able to drive long
distances and will not be able to maintain highway speeds until DEF is
refilled or replaced.
WARNING:Tampering or disabling your vehicle’s exhaust
aftertreatment system will result in severe vehicle performance
limitation including eventual speed limiting to 5 mph.

Your vehicle’s message center will display a series of messages regarding
the amount of DEF available. A systems check will display messages
indicating the amount of DEF available (OK or under
12full) or will
produce a warning message that displays the mileage (kilometers)
remaining as the fluid in the DEF tank nears empty. For more
information on warning messages, see theInformation Displayschapter
of yourOwner’s Manual.
As the DEF level nears empty, the
DEF warning symbol will be
displayed and chimes will sound
with the messages starting at 500 miles (805 km) remaining before DEF
is depleted. The warning symbol and messages will continue until the
DEF tank is refilled.
Continued driving without refilling will result in the following actions as
required by the California Air Resources Board (CARB) and /or U.S.
Environmental Protection Agency (EPA):
•Within a certain number of miles (kilometers) to empty, speed will be
limited upon vehicle restart. Prior to this occurring a message will
appear in the message center.
•Further vehicle operation without refilling your DEF tank will cause
the engine to enter an idle-only condition. This will only occur upon
vehicle refueling or extended idle and will be indicated by a message
in the message center indicating required actions to resume normal
operation. It is required to add a minimum of 0.5 gallons (1.9L) of
DEF to the tank to exit the idle-only condition, but the vehicle will
still be in the speed limiting mode until the tank is refilled completely.
For either vehicle speed limiting or idle-only condition, normal vehicle
operation will resume when the DEF tank is refilled.
Note:When filling the DEF tank from empty, there may be a short delay
before detecting the increased level of DEF. This must occur before full
power is returned.

Filling the DEF tank
WARNING:Make sure that DEF does not come into contact
with eyes, skin or clothing. Should DEF contact your eyes, flush
them with plenty of water and contact a physician. Clean affected skin
with soap and water. If DEF is swallowed, drink plenty of water and
contact a physician immediately.
WARNING:Refill DEF in a well-ventilated area. When opening
the cap on the DEF tank or bottle containing DEF, ammonia
vapors may escape. The vapors can be irritating to skin, eyes and
mucous membranes. Inhaling ammonia vapors can cause burning to the
eyes, throat and nose and cause coughing and watery eyes.
Note:Do not put DEF in the fuel tank. This can cause engine damage
not covered by your vehicle’s warranty.
Note:Immediately wipe away any DEF that has spilled on painted
surfaces with water and a damp cloth to prevent damage to the paint.
Your vehicle is equipped with a DEF tank with a blue-capped filler port
located next to the diesel fuel fill inlet. The tank can be filled using a
nozzle at a DEF filling station (similar to fuel fill) or using a DEF bottle
with a spout. Motorcraft® DEF bottles are recommended as they are
designed to be spill proof and will stop the flow of DEF when the tank is
full. Other aftermarket bottles can be used, but they should have a seal
on the spout and an internal vent tube to achieve best fill performance
and prevent overfilling. Overfilling your DEF tank can cause damage to
the tank. For DEF capacity, see theCapacities and Specifications
chapter.
You can purchase DEF at your authorized dealer, most highway truck
stops or you can contact roadside assistance for help in finding a retailer
that sells DEF. See theCustomer Assistancechapter in theOwner’s
Manualfor more information. In addition, there is a government website
locator for DEF at the following web address that can be used to find the
nearest location to purchase DEF: http://www.afdc.energy.gov/afdc/

FUEL FILTER/WATER SEPARATOR
Diesel Fuel Conditioner Module (DFCM)
The vehicle is equipped with a diesel fuel conditioning module (DFCM)
located on the frame-rail under the driver-side floorboard near the
transmission
Water should be drained from the
module assembly whenever the
warning light comes on and the
message center directs you to drain the water separator. This will occur
when approximately 0.32 pints (150 ml) of water accumulates in the
module. If water level is allowed to exceed this level, the water may be
passed through to the engine and may cause fuel injection equipment
damage.
Draining the DFCM
WARNING:The vehicle must be stopped with the engine off
when draining the DFCM. Fuel may ignite if the separator is
drained while the engine is running or vehicle is moving.
Note:Air will enter into the fuel system if the DFCM is drained while
the system is running. The engine will not operate properly if air enters
the system.
Note:With fuel tank levels above
34tank it may be necessary to loosen
the bowl 3 turns before opening the drain. This will actuate an
anti-siphon valve at the DFCM inlet and prevent the fuel from siphoning
out of the tank.
Note:A loose drain valve can allow air to enter the fuel system and
cause drivetrain issues. The engine will not operate properly. Be sure
that the drain valve is fully tightened.
1. Stop the vehicle andshut offthe engine.
2. Locate the DFCM and place an appropriate container under the drain
port (see illustration).

OCR precautions and safe exhaust position
WARNING:Failure to comply with the following instructions for
operator commanded regeneration (OCR) may result in fire,
serious injury, death and/or property damage.
Before you start OCR, observe/do the following:
•Place the vehicle in P (Park) with the parking brake set on stable,
level ground.
•The vehicle must not be parked in a structure.
•The vehicle must be 10 – 15 feet (3 – 5 meters) away from any
obstructions,
•and must be away from materials that can easily combust or melt such
as: paper, leaves, petroleum products, fuels, plastics and other dry
organic material, such as grass.
•Make sure there is a minimum of 1/8 tank of fuel.
•Make sure all fluids are at proper levels.
Make sure that the louvers (holes) located at the tip of the exhaust are
also clear of any obstructions as they are used to introduce fresh air into
the tailpipe to cool the exhaust gas as it leaves. SeeExhaustunder the
Cleaningchapter for more information.
How to start operator commanded regeneration (OCR)
WARNING:Stay clear of exhaust tip during regeneration. You or
others can be burned.
Note:OCR will not be allowed until DPF load percentage has reached
100% (Full). The DPF load percentage will fluctuate up and down when
driving your vehicle due to active and passive regenerations.
Note:During the use of OCR, you may observe a light amount of white
smoke. This is normal.
OCR will not be allowed to operate
if the service engine soon light is
illuminated

Resonator/Tailpipe assembly maintenance
WARNING:Failure to maintain the functional holes, in the
tailpipe section of the exhaust, clean and free of debris or
foreign material may result in the holes becoming blocked or plugged.
Do not modify or remove the tail-pipe section. Blocked or plugged
holes or removal/modification of the system could result in elevated
exhaust gas temperatures which may result in vehicle/property damage
or personal injury.
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 and/or the
diesel particulate filter (DPF). The diesel oxidation catalytic converter
and/or the DPF heats up to a high temperature after only a short
period of engine operation and can stay hot even after the engine is
turned off. Failure to follow these instructions may result in personal
injury.
Note:Additions of aftermarket devices or modifications to the exhaust
system can reduce the effectiveness of the exhaust system as well as
cause damage to the exhaust system and/or engine. These actions may
also affect the vehicle’s warranty. See theWarranty Guidefor more
information.
The diesel resonator tail-pipe assembly is a uniquely functioning device
that accompanies the Oxidation Catalyst/DPF assembly. The assembly
serves multiple functions. First it serves as an acoustic device to
attenuate exhaust noise. Second it provides an exit path for the exhaust
from the vehicle. It also is designed to help control the temperature of
the exhaust during DPF regeneration events. The visible holes in each
leg of the twin tip and the holes under the shield just inboard of the
right rear tire(s) are functional. The holes need to be kept clear of
mud/debris or foreign material to maintain proper function of the
exhaust system. Clean and remove debris or foreign material if present
as needed. Spraying with a hose during regular washing of vehicle should
help keep holes clean and clear of debris or foreign material.
