CABIN AIR FILTER
Your vehicle is equipped with a cabin air
filter, which gives you and your passenger
the following benefits:
• It improves your driving comfort by
reducing particle concentration.
• It improves the interior compartment
cleanliness.
• It protects the climate control
components from particle deposits.
You can locate the cabin air filter under the
front hood.
Note: Make sure you have a cabin air filter
installed at all times. This prevents foreign
objects from entering the system. Running
the system without a filter in place could
result in degradation or damage to the
system.
Replace the filter at regular intervals. See
Scheduled Maintenance
(page 279).
For additional cabin air filter information,
or to replace the filter, see a qualified
technician.

Ford GT (CGX) Canada/United States of America, enUSA, Edition date: 202010, First-Printing Climate Control

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.
We recommend Top Tier detergent
gasolines, where available, to help
minimize engine deposits and maintain
optimal vehicle and engine performance.
For additional information, refer to
www.toptiergas.com.
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.

EMISSION LAW
WARNING: Do not remove or alter
the original equipment floor covering or
insulation between it and the metal floor
of the vehicle. The floor covering and
insulation protect occupants of the
vehicle from the engine and exhaust
system heat and noise. On vehicles with
no original equipment floor covering
insulation, do not carry passengers in a
manner that permits prolonged skin
contact with the metal floor. Failure to
follow these instructions may result in
fire or personal injury.
U.S. federal laws and certain state laws
prohibit removing or rendering inoperative
emission control system components.
Similar federal or provincial laws may
apply in Canada. We do not approve of any
vehicle modification without first
determining applicable laws. Tampering with emissions
control systems including
related sensors or the Diesel
Exhaust Fluid system can result in reduced
engine power and the illumination of the
service engine soon light. Tampering With a Noise Control
System
Federal laws prohibit the following acts:
•
Removal or rendering inoperative by
any person other than for purposes of
maintenance.
• Repair or replacement of any device or
element of the design incorporated into
a new vehicle for the purpose of noise
control prior to its sale or delivery to
the ultimate purchaser or while it is in
use.
• The use of the vehicle after any person
removes or renders inoperative any
device or element of the design.
The U.S. Environmental Protection Agency
may presume to constitute tampering as
follows:
• Removal of hood blanket, fender apron
absorbers, fender apron barriers,
underbody noise shields or acoustically
absorptive material.
• Tampering or rendering inoperative the
engine speed governor, to allow engine
speed to exceed manufacturer
specifications.
If the engine does not start, runs rough,
experiences a decrease in engine
performance, experiences excess fuel
consumption or produces excessive
exhaust smoke, check for the following:
• A plugged or disconnected air inlet
system hose.
• A plugged engine air filter element.
• Water in the fuel filter and water
separator.
• A clogged fuel filter.
• Contaminated fuel.
• Air in the fuel system, due to loose
connections.
• An open or pinched sensor hose.
• Incorrect engine oil level.

Ford GT (CGX) Canada/United States of America, enUSA, Edition date: 202010, First-Printing Engine Emission Control

•
Incorrect fuel for climatic conditions.
• Incorrect engine oil viscosity for
climactic conditions.
Note: Some vehicles have a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.
Note: If these checks do not help you
correct the concern, have your vehicle
checked as soon as possible.
Noise Emissions Warranty,
Prohibited Tampering Acts and
Maintenance
On January 1, 1978, Federal regulation
became effective governing the noise
emission on trucks over 10,000 lb
(4,536 kg) Gross Vehicle Weight Rating
(GVWR). The preceding statements
concerning prohibited tampering acts and
maintenance, and the noise warranty
found in the Warranty Guide, are
applicable to complete chassis cabs over
10,000 lb (4,536 kg)
GVWR.
CATALYTIC CONVERTER WARNING:
Do not park, idle or
drive your vehicle on dry grass or other
dry ground cover. The emission system
heats up the engine compartment and
exhaust system, creating the risk of fire. WARNING:
The normal operating
temperature of the exhaust system is
very high. Never work around or attempt
to repair any part of the exhaust system
until it has cooled. Use special care when
working around the catalytic converter.
The catalytic converter heats up to a very
high temperature after only a short
period of engine operation and stays hot
after the engine is switched off. WARNING:
Exhaust leaks may
result in entry of harmful and potentially
lethal fumes into the passenger
compartment. If you smell exhaust
fumes inside your vehicle, have your
vehicle inspected immediately. Do not
drive if you smell exhaust fumes.
Your vehicle has various emission control
components and a catalytic converter that
enables it to comply with applicable
exhaust emission standards.
To make sure that the catalytic converter
and other emission control components
continue to work properly:
• Do not crank the engine for more than
10 seconds at a time.
• Do not run the engine with a spark plug
lead disconnected.
• Do not push-start or tow-start your
vehicle. Use booster cables. See Jump
Starting the Vehicle
(page 134).
• Use only the specified fuel listed.
• Do not switch the ignition off when your
vehicle is moving.
• Avoid running out of fuel.
• Perform scheduled maintenance items
according to the specified schedule.
Note: Resulting component damage may
not be covered by the vehicle Warranty.
The scheduled maintenance items listed
in scheduled maintenance information are
essential to the life and performance of
your vehicle and to its emissions system.
If you use anything other than Ford,
Motorcraft or Ford-authorized parts for
maintenance replacements or for service
of components affecting emission control,
use parts equivalent to genuine Ford Motor
Company parts in performance and
durability.

Illumination of the service engine soon
indicator, charging system warning light or
the temperature warning light, fluid leaks,
strange odors, smoke or loss of engine
power could indicate that the emission
control system is not working properly.
An improperly operating or damaged
exhaust system could allow exhaust to
enter the vehicle. Have a damaged or
improperly operating exhaust system
inspected and repaired immediately.
Do not make any unauthorized changes to
your vehicle or engine. By law, vehicle
owners and anyone who manufactures,
repairs, services, sells, leases, trades
vehicles, or supervises a fleet of vehicles
are not permitted to intentionally remove
an emission control device or prevent it
from working. Information about your
vehicle
’s emission system is on the Vehicle
Emission Control Information Decal
located on or near the engine. This decal
also lists engine displacement.
Please consult your warranty information
for complete details.
On-Board Diagnostics (OBD-II)
Your vehicle has a computer known as the
on-board diagnostics system (OBD-II) that
monitors the engine ’s emission control
system. The system protects the
environment by making sure that your
vehicle continues to meet government
emission standards. The OBD-II system
also assists a service technician in properly
servicing your vehicle. When the service engine soon
indicator illuminates, the OBD-II
system has detected a
malfunction. Temporary malfunctions may
cause the service engine soon indicator to
illuminate. Examples are: 1. Your vehicle has run out of fuel
—the
engine may misfire or run poorly.
2. Poor fuel quality or water in the fuel —the engine may misfire or run
poorly.
3. The fuel fill inlet may not have closed properly. See Refueling (page 96).
4. Driving through deep water —the
electrical system may be wet.
You can correct these temporary
malfunctions by filling the fuel tank with
good quality fuel, properly closing the fuel
fill inlet or letting the electrical system dry
out. After three driving cycles without these
or any other temporary malfunctions
present, the service engine soon indicator
should stay off the next time you start the
engine. A driving cycle consists of a cold
engine startup followed by mixed city and
highway driving. No additional vehicle
service is required.
If the service engine soon indicator remains
on, have your vehicle serviced at the first
available opportunity. Although some
malfunctions detected by the OBD-II may
not have symptoms that are apparent,
continued driving with the service engine
soon indicator on can result in increased
emissions, lower fuel economy, reduced
engine and transmission smoothness and
lead to more costly repairs.
Readiness for Inspection and
Maintenance (I/M) Testing
Some state and provincial and local
governments may have
Inspection/Maintenance (I/M) programs
to inspect the emission control equipment
on your vehicle. Failure to pass this
inspection could prevent you from getting
a vehicle registration. If the service engine soon
indicator is on or the bulb does
not work, your vehicle may need
service. See On-Board Diagnostics.
