Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop the vehicle,
turn off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by your
authorized dealer.
Engine Coolant Temperature
Gauge
WARNING
Never remove the coolant reservoir
cap while the engine is running or hot.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop the vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Refer to Special operating
conditions in the scheduled maintenance
information for instructions. Operating the transmission for extended periods of time
with the gauge in the higher than normal
area may cause internal transmission
damage. Altering the severity of the driving
conditions is recommended to lower the
transmission temperature into the normal
range. If the gauge continues to show high
temperatures, see your authorized dealer.
Fuel Gauge
Note:
The fuel gauge may vary slightly
when your vehicle is moving or on a gradient.
Switch the ignition on. The fuel gauge will
indicate approximately how much fuel is
left in the fuel tank. The arrow adjacent to
the fuel pump symbol indicates on which
side of your vehicle the fuel filler door is
located.
The needle should move toward F when
you refuel your vehicle. If the needle points
to E after adding fuel, this indicates your
vehicle needs service soon.
After refueling some variability in needle
position is normal:
• It may take a short time for the needle
to reach F after leaving the gas station.
This is normal and depends upon the
slope of pavement at the gas station.
• The fuel amount dispensed into the
tank is a little less or more than the
gauge indicated. This is normal and
depends upon the slope of pavement
at the gas station.
• If the gas station nozzle shuts off
before the tank is full, try a different
gas pump nozzle.
Low Fuel Reminder
A low fuel reminder triggers when the fuel
gauge needle is at 1/16th.

Low Fuel Level
Illuminates when the fuel level
is low or the fuel tank is nearly
empty. Refuel as soon as
possible.
Low Tire Pressure Warning Illuminates when your tire
pressure is low. If the lamp
remains on with the engine
running or when driving, check
your tire pressure as soon as possible.
It will also illuminate momentarily when
you switch the ignition on to confirm the
lamp is functional. If it does not illuminate
when you switch the ignition on, or begins
to flash at any time, have the system
checked by your authorized dealer.
Powertrain Malfunction/Reduced
Power/Electronic Throttle Control Illuminates when a powertrain
or an AWD fault has been
detected. Contact your
authorized dealer as soon as possible.
Service Engine Soon If the service engine soon
indicator light stays illuminated
after the engine is started, it
indicates that the On-Board Diagnostics
(OBD-II) system has detected a
malfunction of the vehicle emissions
control system. Refer to On-Board
Diagnostics (OBD-II) in the Fuel and
Refueling chapter for more information
about having your vehicle serviced. See
Emission Control System (page 144). If the light is blinking, engine misfire is
occurring which could damage your
catalytic converter. Drive in a moderate
fashion (avoid heavy acceleration and
deceleration) and have your vehicle
serviced immediately. WARNING
Under engine misfire conditions,
excessive exhaust temperatures
could damage the catalytic
converter, the fuel system, interior floor
coverings or other vehicle components,
possibly causing a fire. Have an authorized
dealer service your vehicle immediately. The service engine soon indicator light
illuminates when the ignition is first turned
on prior to engine start to check the bulb
and to indicate whether the vehicle is ready
for Inspection/Maintenance (I/M) testing.
Normally, the service engine soon light will
stay on until the engine is cranked, then
turn itself off if no malfunctions are
present. However, if after 15 seconds the
service engine soon light blinks eight times,
it means that the vehicle is not ready for
I/M testing. See
Emission Control
System (page 144).
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 will switch off. Have the system
checked by your authorized dealer
immediately. See
Using Stability
Control (page 169).

SAFETY PRECAUTIONS
WARNINGS
Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray
and fire. 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. Automotive fuels can cause serious
injury or death if you misuse or
mishandle them.
Fuel ethanol and gasoline may
contain benzene, which is a
cancer-causing agent.
When refueling always shut the
engine off and never allow sparks or
open flames near the filler neck.
Never smoke or use a cell phone while
refueling. Fuel vapor is extremely
hazardous under certain conditions. Avoid
inhaling excess fumes. The flow of fuel through a fuel pump
nozzle can produce static electricity,
which can cause a fire if you pump
fuel into an ungrounded fuel container. Observe the following guidelines when
handling automotive fuel: •
Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If swallowed, call a
physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind can lead
to eye and respiratory tract irritation.
In severe cases, excessive or prolonged
breathing of fuel vapor can cause
serious illness and permanent injury.
• Avoid getting fuel liquid in your eyes. If
you splash fuel in your eyes, remove
contact lenses (if worn), flush with
water for 15 minutes and seek medical
attention. Failure to seek proper
medical attention could lead to
permanent injury.
• Fuels can also be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
wash your skin thoroughly with soap
and water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
“Antabuse ” or other forms of disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors, or skin
contact could cause an adverse
reaction. In sensitive individuals, serious
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.

Super Duty (), enUSA Fuel and Refueling

We recommend regular unleaded gasoline
with a pump (R+M)/2 octane rating of 87.
Some stations offer fuels posted as regular
with an octane rating below 87, particularly
in high altitude areas. We do not
recommend fuels with an octane rating
below 87.
Do not be concerned if your engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, see your
authorized dealer to prevent any engine
damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this
situation may have an adverse effect on
powertrain components.
If you run out of fuel:
•
You may need to switch the ignition
from off to on several times after
refueling to allow the fuel system to
pump the fuel from the tank to the
engine. When restarting, cranking time
takes a few seconds longer than
normal. With keyless ignition, just start
the engine. Crank time will be longer
than usual.
• Normally, adding 1 gallon (3.8 liters) of
fuel is enough to restart the engine. If
the vehicle is out of fuel and on a steep
grade, more than 1 gallon (3.8 liters)
may be required.
• The service engine soon indicator may
come on. For more information on the
service engine soon indicator, See
Warning Lamps and Indicators
(page 79). Refilling With a Portable Fuel
Container 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. Do not try to pry open or push open
the fuel system with foreign objects.
This could damage the fuel system
and its seal and cause personal injury to
you or others. Use the following directions when filling
from a portable fuel container:
1.
Remove the fuel cap from the fuel filler
pipe by rotating it counter clockwise.
2. Slowly insert the portable fuel container into the fuel filler opening.
3. Fill the vehicle with fuel from the portable fuel container.
4. When done, remove the portable fuel container nozzle and reinstall the fuel
cap. Insert fuel cap into fuel filler
opening and turn clockwise until you
hear a click.
REFUELING 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.
141
Super Duty (), enUSA Fuel and Refueling

WARNINGS
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.
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.
