Ford Super Duty (2017 year). Manual - part 47

Continued driving without refilling results
in the following actions as required by the
California Air Resources Board (CARB) and
the U.S. Environmental Protection Agency
(EPA):
•

Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.

•

Further vehicle operation without
refilling the diesel exhaust fluid tank
causes the engine to enter an idle-only
condition. This only occurs upon vehicle
refueling or at an extended idle. A
message indicates the required actions
to resume normal operation. It is
required to add a minimum of 1.0 gal
(3.8 L) of diesel exhaust fluid to the
tank to exit the idle-only condition, but
your vehicle is still in the speed-limiting
mode until you refill the tank
completely.

Note: For either vehicle speed limiting or
idle-only condition, normal vehicle operation
resumes when you refill the diesel exhaust
fluid tank.

Note: When filling the diesel exhaust fluid
tank from empty, there may be a short delay
before detecting the increased level of fluid.
The increased level detection must occur
before your vehicle returns to full power.

Diesel Exhaust Fluid Guidelines
and Information

•

Use only diesel exhaust fluid that
carries the American Petroleum
Institute (API) certified diesel exhaust
fluid trademark or ISO 22241.

•

Do not put diesel exhaust fluid in the
diesel fuel tank.

•

Do not overfill the diesel exhaust fluid
tank.

•

Diesel exhaust fluid is corrosive.

•

Do not re-use the diesel exhaust fluid
container once it is emptied.

•

Avoid spilling diesel exhaust fluid on
painted surfaces, carpeting or plastic
components. Immediately wipe away
any diesel exhaust fluid that has spilled
with a damp cloth and water. If it has
already crystallized, use warm water
and a sponge.

•

Store diesel exhaust fluid out of direct
sunlight and in temperatures between
23°F (-5°C) and 68°F (20°C).

•

Diesel exhaust fluid freezes below 12°F
(-11°C).

•

Do not store the diesel exhaust fluid
bottle in your vehicle. If it leaks it could
cause damage to interior components
or release an ammonia odor inside your
vehicle.

•

Diesel exhaust fluid is non-flammable,
non-toxic, colorless and water-soluble
liquid.

•

The system has a diesel exhaust fluid
quality sensor. Dilution of diesel
exhaust fluid or use of any other liquid
in the SCR system leads to a diesel
exhaust fluid system fault, eventually
leading to the vehicle only operating in
idle-only mode.

•

Do not dilute diesel exhaust fluid with
water or any other liquid.

•

An ammonia odor may be smelled
when the cap is removed or during
refill. Refill diesel exhaust fluid in a well
ventilated area.

Typical Diesel Exhaust Fluid Usage
When Using the Power Take Off (PTO)

Continuous PTO use—Minimal PTO use

0–7,800 mi (0–12,550 km)

Contaminated Diesel Exhaust
Fluid or Inoperative Selective
Catalytic Reduction System

Selective catalytic reduction systems are
sensitive to contamination of the diesel
exhaust fluid. Maintaining the purity of the
fluid is important to avoid system
malfunctions. If you remove or drain the
diesel exhaust fluid tank, do not use the
same fluid to refill the tank. The system
has a sensor to monitor fluid quality.

E163176

A warning lamp illuminates and
a message appears in the
information display if the system

becomes contaminated or inoperative.

Continued driving without replacing diesel
exhaust fluid or having the selective
catalytic reduction system repaired results
in the following actions as required by the
California Air Resources Board (CARB) and
U.S. Environmental Protection Agency
(EPA):
•

Within a preset distance to empty,
speed is limited upon vehicle restart.
Prior to this occurring a message
appears in the information display.

•

Further vehicle operation without
replacing contaminated diesel exhaust
fluid causes the engine to enter an
idle-only condition. This only occurs
upon vehicle refueling, vehicle idling in
park for 1 hour, or engine shutdown for
10 minutes or more and is indicated by
a message in the information display
indicating required actions to resume
normal operation.

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.

REFUELING - GASOLINE

WARNINGS

Fuel vapor burns violently and a fuel
fire can cause severe injuries.

Read and follow all the instructions
on the pump island.

Turn off your engine when you are
refueling.

Do not smoke if you are near fuel or
refueling your vehicle.

Keep sparks, flames and smoking
materials away from fuel.

Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle. This is

against the law in some places.

Keep children away from the fuel
pump; never let children pump fuel.

Do not use personal electronic
devices while refueling.

Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into

the fuel tank.

Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this

will fill the expansion space in the fuel tank
and could lead to fuel overflowing.

Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.

192

Use the following guidelines to avoid
electrostatic charge build-up when filling
an ungrounded fuel container:
•

Place approved fuel container on the
ground.

•

Do not fill a fuel container while it is in
the vehicle (including the cargo area).

•

Keep the fuel pump nozzle in contact
with the fuel container while filling.

•

Do not use a device that would hold
the fuel pump handle in the fill position.

Fuel Filler Cap

WARNINGS

The fuel system may be under
pressure. If you hear a hissing sound
near the fuel filler door, do not refuel

until the sound stops. Otherwise, fuel may
spray out, which could cause serious
personal injury.

If you do not use the proper fuel filler
cap, excessive pressure or vacuum
in the fuel tank may damage the fuel

system or cause the fuel cap to disengage
in a collision, which may result in possible
personal injury.

Note: If you must replace the fuel filler cap,
replace it with a fuel filler cap that is
designed for your vehicle. The customer
warranty may be void for any damage to the
fuel tank or fuel system if the correct
genuine Ford, Motorcraft or other certified
fuel filler cap is not used.

Your fuel tank filler cap has an indexed
design with a 1/4th turn on and off feature.
When fueling your vehicle:

1.

Put your vehicle in park (P).

2. Switch the engine off.

3. Carefully turn the filler cap

counterclockwise until it spins off.

4. Pull to remove the cap from the fuel

filler pipe.

5. To install the cap, align the tabs on the

cap with the notches on the filler pipe.

6. Turn the filler cap clockwise 1/4 of a

turn clockwise until it clicks at least
once.

If the Check Fuel Cap light or a Check Fuel
Cap message appears in the instrument
cluster and stays on after you start the
engine, you may not have installed the fuel
filler properly.

If the fuel cap light remains on, at the next
opportunity, safely pull off of the road,
remove the fuel filler cap, align the cap
properly and reinstall it. The check fuel cap
light or Check fuel cap message may not
reset immediately. It may take several
driving cycles for the indicators to turn off.
A driving cycle consists of an engine
start-up (after four or more hours with the
engine off) followed by normal city and
highway driving.

REFUELING - DIESEL

WARNINGS

Read and follow all the instructions
on the pump island.

Stay outside your vehicle and do not
leave the fuel pump unattended
when refueling your vehicle.

Keep children away from the fuel
pump. Never let children pump fuel.

Wait at least 10 seconds before
removing the fuel pump nozzle to
allow any residual fuel to drain into

the fuel tank.

Do not remove the fuel pump nozzle
from its fully inserted position when
refueling.

193

WARNINGS

When refueling always shut the
engine off and never allow sparks or
open flames near the fuel tank filler

valve. Never smoke or use a cell phone
while refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes.

Stop refueling after the fuel pump
nozzle automatically shuts off for the
second time. Failure to follow this

will fill the expansion space in the fuel tank
and could lead to fuel overflowing.

The fuel system may be under
pressure. If the fuel filler cap is
venting vapor or if you hear a hissing

sound, wait until it stops before completely
removing the fuel filler cap. Otherwise, fuel
may spray out and injure you or others.

If you do not use the proper fuel filler
cap, excessive pressure or vacuum
in the fuel tank may damage the fuel

system or cause the fuel cap to disengage
in a collision, which may result in possible
personal injury.

Note: If you must replace the fuel filler cap,
replace it with a fuel filler cap designed for
your vehicle. The vehicle Warranty may be
void for any damage to the fuel tank or fuel
system if the correct genuine Ford or
Motorcraft® fuel filler cap is not used.

Fueling Tips

If air is allowed to enter the fuel system the
engine automatically purges any trapped
air. To purge the air sooner: prior to engine
start, prime the system by turning the key
to on for 30 seconds then to off. Repeat
this several times. The engine may run
rough and produce white smoke while air
is in the system. This is normal.

Use only clean, approved containers that
will prevent the entry of dirt or water
whenever you store diesel fuel.

Diesel fuel must not be stored in a
galvanized container. The fuel will dissolve
the zinc in the galvanized container. The
zinc will then remain in the fuel. If you run
the contaminated fuel through the engine,
the zinc will deposit in the fuel injectors
causing expensive-to-repair damage.

Diesel fuel dispensing nozzle fill rate

Your vehicle has a fuel fill pipe that is able
to accept fuel up to 20 gal (76 L) per
minute from an 1.2 in (30 mm)
fuel-dispensing nozzle. Pumping fuel at
greater flow rates may result in premature
nozzle shut-off or spit back.

Truck stops have pumps and nozzles
designed for larger, heavy-duty trucks.
When refueling at truck stops: if the nozzle
shuts off repeatedly when refueling, wait
5–10 seconds; then use a slower rate of
flow, do not depress the nozzle trigger as
far.

Refueling

When fueling your vehicle do the following:

1.

Fully open the fuel tank filler door until
it engages and remove the fuel tank
filler cap. The fuel tank filler cap has
an indexed design with a 1/4 turn
on/off feature. Carefully turn the filler
cap counterclockwise until it spins off.
