CHILD RESTRAINT AND
SEATBELT MAINTENANCE
Inspect the vehicle seatbelts and child
safety seat systems periodically to make
sure they work properly and are not
damaged. Inspect the vehicle and child
restraint seatbelts to make sure there are
no nicks, tears or cuts. Replace if
necessary. All vehicle seatbelt assemblies,
including retractors, buckles, front seatbelt
buckle assemblies, buckle support
assemblies (slide bar-if equipped),
shoulder belt height adjusters (if
equipped), shoulder belt guide on seat
backrest (if equipped), child safety seat
LATCH and tether anchors, and attaching
hardware, should be inspected after a
crash. Read the child restraint
manufacturer's instructions for additional
inspection and maintenance information
specific to the child restraint.
We recommend that all seatbelt
assemblies in use in vehicles involved in a
crash be replaced. However, if the crash
was minor and an authorized dealer finds
that the belts do not show damage and
continue to operate properly, they do not
need to be replaced. Seatbelt assemblies
not in use during a crash should also be
inspected and replaced if either damage
or improper operation is noted.
Properly care for seatbelts. See Vehicle
Care (page 255). SEATBELT EXTENSIONS WARNING:
Persons who fit into
the vehicle's seatbelt should not use an
extension. Unnecessary use could result
in serious personal injury in the event of
a crash. WARNING:
Only use extensions
provided free of charge by our dealers.
The dealer will provide an extension
designed specifically for this vehicle,
model year and seating position. The use
of an extension intended for another
vehicle, model year or seating position
may not offer you the full protection of
your vehicle's seatbelt restraint system. WARNING:
Never use seatbelt
extensions to install child restraints. WARNING:
Do not use a seatbelt
extension with an inflatable seatbelt. WARNING:
Do not use extensions
to change the way the seatbelt fits
across the torso, over the lap or to make
the seatbelt buckle easier to reach.
If, because of body size or driving position,
it is not possible to properly fasten the
seatbelt over your lap and shoulder, an
extension that is compatible with the
seatbelts is available free of charge from
our dealers. Only use our seatbelt
extensions made by the original equipment
seatbelt manufacturer with our seatbelts.
Ask your authorized dealer if your extension
is compatible with your vehicle restraint
system.

MyKey, and at 50 mi (80 km), 25 mi
(40 km), 10 mi (20 km) and 0 mi (0 km)
for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Distance to Empty
Indicates the approximate distance your
vehicle can travel on the fuel remaining in
the tank. Changes in driving pattern can
cause the value to not only decrease but
also increase or stay constant for periods
of time.
Configurable Gauge
Transmission Fluid Temperature Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator is in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop your vehicle as soon
as possible and verify the airflow is not
restricted by snow or debris blocking
airflow through the grille.
Special operating conditions such as
snowplowing, towing, or off-road use may
cause higher than normal operating
temperatures. See
Special Operating
Conditions Scheduled Maintenance
(page
329).
To lower the transmission temperature
into the normal range, alter the severity of
your driving conditions. Operating the

personal injury or sickness may result.
If you splash fuel on your skin, promptly
wash your skin thoroughly with soap
and water. Consult a physician
immediately if you experience an
adverse reaction.
Low Fuel Pressure (If Equipped)
Diesel engine vehicles have a low fuel
pressure detection system.
The following are possible causes for a low
fuel pressure warning message to appear
in the information display:
• Cold start or during cold operation
below
32°F (0°C). If the low fuel
pressure message appears during a
cold start or up to 10 minutes after the
initial cold start, monitor the
information display. If the low fuel
pressure message disappears and does
not re-appear after the engine has fully
warmed up, waxed or gelled fuel is
what most likely caused the message.
Do not use alcohol based additives to
correct fuel gelling. This may result in
damage to the fuel injectors and
systems. Use an anti-gel additive. See
Capacities and Specifications (page
288
).
Note: The vehicle Warranty may be void if
you use additives that do not meet or
exceed Ford specifications. If the low fuel
pressure message persistently appears after
re-fueling and then disappears when the
engine has fully warmed up, consider using
different fuel sources. •
Low fuel operation: If the low fuel
pressure message appears when your
vehicle is warm and during low fuel
tank level operation (near empty),
refuel your vehicle. If the message
reappears after fueling, see below. If
the message does not come back, the
low fuel pressure condition was due to
low fuel levels in the fuel tank.
• Normal operation: If the low fuel
pressure message appears during
normal operation when the engine is
fully warm, and fuel level is not low,
you must change the fuel filters
regardless of the maintenance
schedule interval.
• If replacement of the fuel filter does
not remedy the low fuel pressure
message during normal operation as
defined above, take the vehicle to an
authorized dealer.
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)
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 can 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.

F650750 (TBC) , enUSA, Edition date: 202010, Second-Printing Fuel and Refueling

To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
•
Confirm the biodiesel content of the
fuel to be 20% biodiesel or less, also
known as B20.
• Only use biodiesel fuel of good quality
that complies with industry standards.
• Follow the recommended service
maintenance intervals. See
Scheduled Maintenance (page 319).
• Do not store biodiesel fuel in the fuel
tank for more than 1 month.
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequent LOW FUEL PRESSURE
message appearing.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel fuels greater than
20% or any diesel fuel not intended for
highway use. Red dye is used to identify
fuels intended for agricultural and
non-highway use. Damage to the fuel
injection system, engine and exhaust
catalyst can occur if an improper fuel is
used.
Use of biodiesel in concentrations greater
than 20% could cause damage to your
vehicle, including engine and/or exhaust
catalyst and particulate filter failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that could
result in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
SAE 5W-40 or SAE 15W-40 oil is
recommended for fuels with greater than
5% biodiesel, also known as B5. Follow
the recommended oil change intervals and
other maintenance when operating on
biodiesel. See
Special Operating
Conditions Scheduled Maintenance
(page
329). Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in a diesel fuel. Biodiesel content is often
indicated with the letter B followed by the
percent of biodiesel in the fuel. For
example, B20 indicates a fuel containing
20% biodiesel. Ask the service station
attendant to confirm the biodiesel content
of a diesel fuel if you do not see a label on
the fuel pump.
Note:
Biodiesel fuels degrade more easily
than diesel fuels not containing biodiesel.
Degraded or oxidized biodiesel can damage
fuel system seals and plastics and corrode
steel parts. If you plan to park or store your
vehicle for more than 1 month, empty your
vehicle fuel tank of biodiesel fuel. Fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
During cold weather, if you have problems
operating on biodiesel, you may need to
use a diesel fuel with lower biodiesel
content, try another brand, or discontinue
the use of biodiesel.
Diesel Fuel Additives
It should not be necessary to add any
aftermarket additives to your fuel if you
use a high quality diesel fuel that conforms
to ASTM industry specifications.
Aftermarket additives can damage the fuel
injector system or engine.
Use Motorcraft® cetane booster or an
equivalent cetane booster additive if you
suspect fuel has low cetane. Use
Motorcraft® anti-gel & performance
improver or an equivalent additive if there
is fuel gelling.
Do not use alcohol-based additives to
improve cetane quality, to prevent fuel
gelling or any other use. The use of alcohol
additives may result in damage to the fuel
injectors and system. See Capacities and
Specifications (page 288).
