fuel type FORD SUPER DUTY 2021 Owners Manual

Your vehicle has electronic control units
that have data recording functionality and
the ability to permanently or temporarily
store data. This data could include
information on the condition and status of
your vehicle, vehicle maintenance
requirements, events and malfunctions.
The types of data that can be recorded are
described in this section. Some of the data
recorded is stored in event logs or error
logs.
Note:
Error logs are reset following a service
or repair.
Note: We may provide information in
response to requests from law enforcement,
other government authorities and third
parties acting with lawful authority or
through a legal process. Such information
could be used by them in legal proceedings.
Data recorded includes, for example:
• Operating states of system
components, for example, fuel level,
tire pressure and battery charge level.
• Vehicle and component status, for
example, wheel speed, deceleration,
lateral acceleration and seatbelt
status.
• Events or errors in essential systems,
for example, headlamps and brakes.
• System responses to driving situations,
for example, airbag deployment and
stability control.
• Environmental conditions, for example,
temperature.
Some of this data, when used in
combination with other information, for
example, an accident report, damage to a
vehicle or eyewitness statements, could
be associated with a specific person. Service Data
Service data recorders in your vehicle are
capable of collecting and storing
diagnostic information about your vehicle.
This potentially includes information about
the performance or status of various
systems and modules in the vehicle, such
as engine, throttle, steering or brake
systems. In order to properly diagnose and
service your vehicle, Ford Motor Company
(Ford of Canada in Canada), and service
and repair facilities may access or share
among them vehicle diagnostic
information received through a direct
connection to your vehicle when
diagnosing or servicing your vehicle.

FUEL QUALITY - DIESEL
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Required (United
States/Canada/Puerto Rico/U.S.
Virgin Islands And Other Locales)
Note:
Your warranty will not cover damage
caused by using an improper type of fuel or
fuel additive.
Note: Do not blend used engine oil with
diesel fuel under any circumstances.
Blending used oil with the fuel will
significantly increase your vehicle ’s exhaust
emissions and reduce engine life due to
increased internal wear.
We recommend Top Tier diesel fuel where
available to help minimize engine deposits
and maintain optimal vehicle and engine
performance. For additional information,
refer to www.toptiergas.com.
You should use Ultra-Low Sulfur Diesel
fuel (also known as ULSD) designated as
number 1-D or 2-D with a maximum of
15-ppm sulfur in your diesel vehicle. You
may operate your vehicle on diesel fuels
containing up to 20% biodiesel, also
known as B20. These fuels should meet
the ASTM D975 diesel or the ASTM D7467
B6-B20 biodiesel industry specifications.
Outside of North America, use fuels
meeting EN590 or equivalent local market
standard. Using low sulfur diesel fuel
(16-500 ppm) or high sulfur
diesel fuel (greater than 500
ppm) in your diesel engine will cause
certain emission components to
malfunction which may also cause the
service engine soon light to illuminate
indicating an emissions-related concern. Diesel fuel is adjusted seasonally for cold
temperature. For best results at
temperatures below 19°F (-7°C), we
recommended using a diesel fuel which
has been seasonally adjusted for the
ambient conditions.
Fuel Requirements - Choosing The
Right Fuel: Vehicles Operated
Where Ultra Low Sulfur Diesel Fuel
Is Not Required
For the engine to operate reliably on
low-sulfur or high-sulfur diesel fuel, the
engine must be a factory built high-sulfur
engine (available as a dealer order option
for select markets) or an ultra low sulfur
diesel fuel configured engine that has been
retrofitted for high-sulfur diesel fuel using
Ford Motor Company dealer service parts.
Failure to use retrofit components other
than those available through your
authorized dealer will result in coolant
system damage, engine overheating,
selective catalyst reduction system or
diesel particulate filter damage and
possible base engine damage.
Use only a diesel engine configured for use
with high sulfur diesel fuel in markets with
diesel fuel that has sulfur content greater
than 15 ppm. Using low sulfur diesel fuel
(16–500 ppm) or high sulfur diesel fuel
(greater than 500 ppm) in a diesel engine
designed to use only Ultra Low Sulfur
Diesel fuel may result in damage to engine
emission control devices and the
aftertreatment system, potentially
rendering the vehicle inoperable.
Vehicles with engines configured for use
with high sulfur diesel fuel are only
available for sale in countries where ultra
low sulfur diesel fuel is generally not
available or mandated by the government.
Vehicles originally sold in a ultra low sulfur
diesel fuel market that are subsequently

USING FOUR-WHEEL DRIVE
Note:
For important information regarding
the safe operation of this type of vehicle,
see General Information in the Wheels and
Tires chapter.
Note: Do not use 4H or 4L mode on dry,
hard surfaced roads. Doing so can produce
excessive noise, increase tire wear and may
damage drive components. 4X4 mode is
only intended for consistently slippery or
loose surfaces. Use of 4L mode on these
surfaces may produce some noise, such as
occasional clunks, but will not damage drive
components.
Note: If 4X4 low is selected while the
vehicle is moving above 3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper operation.
Note: You can switch on and switch off the
electronic locking differential by pulling the
4WD control (4WD vehicles) or turning the
electronic locking differential control (2WD
vehicles). See
Electronic Locking
Differential (page 221).
Electronic Shift-On-the-Fly
(ESOF) 4WD system
(If Equipped)
Note: If 4X4 Low is selected while the
vehicle is moving above
3 mph (5 km/h),
the 4WD system will not perform a shift.
This is normal and should be no reason for
concern. Refer to Shifting to or from 4L (4X4
Low) for proper system operation.
Note: Auto-manual hub locks can be
manually locked by rotating the hub lock
control from AUTO to LOCK. For proper operation, make sure that each
hub is fully engaged and that both hub
locks are set to the same position (both
set to LOCK or both set to AUTO). To
engage LOCK, turn the hub locks
completely clockwise; to engage AUTO,
turn the hub locks completely
counterclockwise.
The ESOF 4WD system:
•
Provides 4x4 High engagement and
disengagement while the vehicle is
moving.
• Is operated by a rotary control located
on the instrument panel that allows
you select 4x2, 4x4 High or 4x4 Low
operation.
• Uses auto-manual hub locks that can
be engaged and disengaged
automatically based on the 4x4 mode
selected.
• Will increase fuel economy when used
in the hub lock's recommended AUTO
mode.
4WD Indicator Lights
Note: When a 4X4 system fault is present,
the system will typically remain in whichever
4X4 mode was selected prior to the fault
condition occurring. It will not default to 4X2
in all circumstances. When this warning is
displayed, have your vehicle serviced by an
authorized dealer.

You should drain water from the
module assembly whenever the
warning light illuminates or a
message appears in the information
display advising you to drain the water
separator. This occurs when approximately
6.76 fl oz (200 ml) of water accumulates
in the module. If you allow the water level to exceed this level, the water may pass
through to the engine and may cause fuel
injection equipment damage.

GENERAL INFORMATION
Use only approved wheel and tire sizes,
using other sizes could damage your
vehicle. If you change the diameter of the
tires from that fitted at the factory, the
speedometer may not display the correct
speed. If you intend to change the size of
the wheels from that fitted by the
manufacturer, you can check the suitability
with an authorized dealer.
Additional information related to the
functionality and maintenance of your tires
can be found later in this chapter. See Tire
Care (page 404).
You can find the recommended tire
inflation pressures can on the Tire Label,
which is on the B-pillar or the edge of the
driver door. You can also find this
information on the Safety Compliance
Certification Label, affixed to either the
door hinge pillar, door-latch post, or the
door edge that meets the door latch post;
next to the driver seating position.
We strongly recommend maintaining these
tire pressures at all times. Failure to follow
the tire pressure recommendations can
cause uneven treadwear patterns, reduced
fuel economy, and adversely affect the
way your vehicle handles.
Note: Check and set the tire pressure at the
ambient temperature in which you are
intending to drive your vehicle and when the
tires are cold.
Note: Check your tire pressures at least
once per month.
If your vehicle has a spare tire, set the
pressure to the highest value given for your
vehicle and tire size combination. Notice to utility vehicle and truck
owners WARNING:
Utility vehicles have a
significantly higher rollover rate than
other types of 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. WARNING:
In a rollover crash, an
unbelted person is significantly more
likely to die than a person wearing a
seatbelt. WARNING:
Do not become
overconfident in the ability of four-wheel
drive vehicles. Although a four-wheel
drive vehicle may accelerate better than
a two-wheel drive vehicle in low traction
situations, it won't stop any faster than
two-wheel drive vehicles. Always drive
at a safe speed.
Utility vehicles and trucks handle
differently than passenger cars in the
various driving conditions that are
encountered on streets, highways and
off-road. Utility vehicles and trucks are not
designed for cornering at speeds as high
as passenger cars any more than low-slung
sports cars are designed to perform
satisfactorily under off-road conditions.
