Ford GT (2018 year). Manual — part 23

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 inlet, do not refuel

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

Fuels can cause serious injury or
death if misused or mishandled.

Fuel 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 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.

Follow these guidelines when refueling:
•

Extinguish all smoking materials and
any open flames before refueling your
vehicle.

•

Always switch the engine off before
refueling.

•

Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours.

•

Avoid inhaling fuel vapors. Inhaling fuel
vapor 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 in your eyes. If you
splash fuel in your eyes, immediately
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 be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.

•

Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.

FUEL QUALITY

Choosing the Right Fuel

Use only premium unleaded gasoline with
a minimum pump (R+M)/2 octane rating
of 91. For optimal performance, use
premium unleaded gasoline with an octane
rating of 93 or higher.

The use of the correct fuel is an important
part of the proper maintenance of your
vehicle, and a condition of the vehicle
Warranty. For this vehicle, the use of
gasoline with an octane level of 91 or
higher is required. The use of gasoline with
an octane rating lower than 91 will
invalidate the vehicle Warranty. It can
degrade vehicle performance and lead to
severe mechanical damage.

Note: Use of any fuel other than those
recommended can impair the emission
control system and cause a loss of vehicle
performance.

Do not use:
•

Diesel fuel.

•

Fuels containing kerosene or paraffin.

•

Fuel containing more than 15% ethanol
or E85 fuel.

•

Fuels containing methanol.

•

Fuels containing metallic-based
additives, including manganese-based
compounds.

•

Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).

•

Leaded fuel (using leaded fuel is
prohibited by law).

The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.

Do not be concerned if the engine
sometimes knocks lightly. However, if it
knocks heavily under most driving
conditions while you are using fuel with the
recommended octane rating, contact an
authorized dealer to prevent any engine
damage.

FUEL FILLER FUNNEL
LOCATION

The fuel filler funnel is located in the
storage compartment under the rear hatch.

RUNNING OUT OF FUEL

Running out of fuel can cause damage not
covered by the vehicle Warranty.

If your vehicle runs out of fuel:
•

Add a minimum of 1.3 gal (5 L) of fuel
to restart the engine.

•

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.

Note: If your vehicle is on a steep slope,
more fuel may be required.

Filling a Portable Fuel Container

WARNING

Flow of fuel through a fuel pump
nozzle can produce static electricity.
This can cause a fire if you are filling

an ungrounded fuel container.

Use the following guidelines to avoid
electrostatic charge build-up, which can
produce a spark, when filling an
ungrounded fuel container:
•

Only use an approved fuel container to
transfer fuel to your vehicle. Place the
container on the ground when filling it.

•

Do not fill a fuel container when it is
inside your vehicle (including the cargo
area).

•

Keep the fuel pump nozzle in contact
with the fuel container when filling it.

•

Do not use a device that holds the fuel
pump nozzle lever in the fill position.

Adding Fuel From a Portable Fuel
Container

WARNINGS

Do not insert the nozzle of a fuel
container or an aftermarket funnel
into the fuel filler neck. This may

damage the fuel system filler neck or its
seal and cause fuel to run onto the ground.

Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel

system and its seal and cause injury to you
or others.

Do not dispose of fuel in the
household refuse or the public
sewage system. Use an authorized

waste disposal facility.

When refueling the vehicle fuel tank from
a fuel container, use the fuel filler funnel
included with your vehicle. See Fuel Filler
Funnel Location (page 95).

Note: Do not use aftermarket funnels as
they may not work with the capless fuel
system and can damage it.

When refueling the vehicle fuel tank from
a fuel container, do the following:

1.

Fully open the fuel filler door.

2. Fully insert the fuel filler funnel into the

fuel filler inlet.

E157452

3. Add fuel to your vehicle from the fuel

container.

4. Remove the fuel filler funnel.

5. Fully close the fuel filler door.

6. Clean the fuel filler funnel and place it

back in your vehicle or correctly dispose
of it.

Note: Extra funnels can be purchased from
an authorized dealer if you choose to
dispose of the funnel.

REFUELING

WARNINGS

Do not overfill the fuel tank. The
pressure in an overfilled tank may
cause leakage and lead to fuel spray

and fire.

Do not try to pry open or push open
the capless fuel system with foreign
objects. This could damage the fuel

system and its seal and cause injury to you
or others.

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

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.

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

the fuel tank.

Stop refueling when the fuel pump
nozzle automatically shuts off for the
first time. Failure to follow this will

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

Note: Your vehicle does not have a fuel filler
cap.

Note: You must unlock your vehicle before
opening and closing the fuel tank filler door.

E228356

1.

Fully open the fuel tank filler door until
it engages.

Note: When you insert the correct size fuel
pump nozzle a spring loaded inhibitor will
open.

2. Insert the fuel pump and keep it resting

on the cover of the fuel tank filler pipe
opening.

3. Hold the fuel pump nozzle in position

B when refueling. Holding the fuel
nozzle in position A can affect the flow
of fuel and shut off the fuel nozzle
before the fuel tank is full.
