Powertrain Malfunction/Reduced
Power/Electronic Throttle Control
Illuminates when a powertrain
or a 4WD fault has been
detected. Have your vehicle
checked as soon as possible.
Service Engine Soon Illuminates when you switch the
ignition on prior to engine start
to check the bulb and to indicate
whether your vehicle is ready for Inspection
and Maintenance (I/M) testing.
Normally, it illuminates until the engine is
cranked and automatically turns off if no
malfunctions are present. However, if after
15 seconds it flashes eight times, this
indicates that your vehicle is not ready for
Inspection and Maintenance (I/M) testing.
See Emission Law (page 194).
If it illuminates when the engine is running
this indicates a malfunction. The On Board
Diagnostics system has detected a
malfunction of the vehicle emission control
system.
If it flashes, engine misfire may be
occurring. Increased exhaust gas
temperatures could damage the catalytic
converter or other vehicle components.
Drive in a moderate fashion, avoid heavy
acceleration and deceleration, and have
your vehicle checked immediately.
Stability Control Illuminates when the system is
active. If it remains illuminated
or does not illuminate when you
switch the ignition on, this indicates a
malfunction. During a malfunction, the
system switches off. Have the system
checked immediately. See
Using
Stability Control (page 229). Stability Control Off Illuminates when you switch the
system off. It goes out when you
switch the system back on or
when you switch the ignition off.
See Using Stability Control (page 229).
Tailgate Ajar Illuminates when the tailgate is
not completely closed or when
opened and then closed when
the transmission is in any gear other than
park (P).
Transmission Tow/Haul
(If Equipped) Illuminates when the tow/haul
feature is activated. If the light
flashes steadily, have the system
checked immediately as damage to the
transmission could occur.
Wait To Start
(If Equipped) Illuminates when you switch the
ignition on as part of the
pre-start system. Wait until the
wait to start indicator turns off before
attempting to start your vehicle. See
Starting a Diesel Engine
(page 177).
Water In Fuel
(If Equipped) WARNING:
Do not drain the
water-in-fuel separator while the engine
is running. Failure to follow this warning
may result in fire, serious injury, death or
property damage.

•
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. WARNING: Do not allow people or
animals in truck beds that have
modifications, such as bed covers or
slide-in campers, when the engine is
running. Exhaust fumes are toxic. Failure
to follow this instruction could result in
personal injury or death.
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 327).
• 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: Your vehicle warranty does not cover
resulting component damage.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.

Note:
For vehicle speed limiting or idle-only
condition, normal vehicle operation resumes
when you repair the contaminated system.
To service a contaminated or inoperative
system, see an authorized dealer.
DIESEL PARTICULATE FILTER
(IF EQUIPPED)
The filter forms part of the emissions
reduction system on your vehicle. It filters
harmful diesel particulates (soot) from the
exhaust gas.
Regeneration WARNING: Do not park or idle your
vehicle over dry leaves, dry grass or other
combustible materials. The regeneration
process creates very high exhaust gas
temperatures and the exhaust will
radiate a considerable amount of heat
during and after regeneration and after
you have switched the engine off. This is
a potential fire hazard.
Note: Avoid running out of fuel.
Note: During regeneration at low speed or
engine idle, you may smell a hot metallic
odor and could notice a clicking metallic
sound. This is due to high temperatures
reached during regeneration and is normal.
Note: Changes in the engine or exhaust
sound may be heard during the regeneration
process.
The diesel particulate filter on your vehicle
requires periodic regeneration to maintain
its correct function. Your vehicle will carry
out this process automatically. If your journeys meet one of the following
conditions:
•
You drive only short distances.
• You frequently switch the ignition on
and off.
• Your journeys contain a high level of
acceleration and deceleration.
You must carry out occasional trips with
the following conditions to assist the
regeneration process:
• Drive your vehicle in more favorable
conditions, which you will find at higher
vehicle speeds in normal driving, on a
main road or freeway for a minimum
of 20 minutes. This drive may include
short stops that will not affect the
regeneration process.
• Avoid prolonged idling and always
observe speed limits and road
conditions.
• Do not switch the ignition off.
• Select a suitable gear to ideally
maintain engine speed between 1500
and 3000 RPM.
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.

Super Duty (TFE) Canada/United States of America, enUSA, Edition date: 202008, Third-Printing- Engine Emission Control

•
Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or
the area in and around these locations.
• Cover the battery, power distribution
box, and air filter assembly to prevent
water damage when cleaning the
engine.
CLEANING THE EXHAUST -
6.7L DIESEL 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. The visible holes in the exhaust 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.
CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
