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.
101
Ford GT (CGX) Canada/United States of America, enUSA, Edition date: 202010, First-Printing Engine Emission Control

Your vehicle may not pass the I/M test if
the service engine soon indicator is on or
not working properly (bulb is burned out),
or if the OBD-II system has determined
that some of the emission control systems
have not been properly checked. In this
case, the vehicle is not ready for I/M
testing.
If the vehicle
’s engine or transmission has
just been serviced, or the battery has
recently run down or been replaced, the
OBD-II system may indicate that the
vehicle is not ready for I/M testing. To
determine if the vehicle is ready for I/M
testing, turn the vehicle on for 15 seconds
without cranking the engine. If the service
engine soon indicator blinks eight times, it
means that the vehicle is not ready for I/M
testing; if the service engine soon indicator
stays on solid, it means that your vehicle
is ready for I/M testing.
The OBD-II system checks the emission
control system during normal driving. A
complete check may take several days.
If the vehicle is not ready for I/M testing,
you can perform the following driving cycle
consisting of mixed city and highway
driving:
1. 15 minutes of steady driving on an expressway or highway followed by 20
minutes of stop-and-go driving with at
least four 30-second idle periods.
2. Allow your vehicle to sit for at least eight hours with the ignition off. Then,
start the vehicle and complete the
above driving cycle. The vehicle must
warm up to its normal operating
temperature. Once started, do not turn
off the vehicle until the above driving
cycle is complete.
If the vehicle is still not ready for I/M
testing, you need to repeat the above
driving cycle.

Note:
The GT battery charger and
maintainer is designed for the Lithium
battery used on Ford GT. Use only this
device. A charger designed for a lead acid
battery may damage the lithium battery in
your GT.
Battery Management System
The battery management system monitors
battery conditions and takes actions to
extend battery life. If excessive battery
drain is detected, the system temporarily
disables the electrical systems to protect
the battery.
Use the charger to bring the battery back
to full charge.
Electrical Accessory Installation
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.
ADJUSTING THE HEADLAMPS
Headlamp Aim Target 8 ft (2.4 m).
A
Center height of lamp to ground.
B 25 ft (7.6 m).
C
Horizontal reference line.
D
Vertical Aim Adjustment
1. Park your vehicle on a level surface approximately 25 ft (7.6 m) away from
a vertical wall or screen.
2. Apply the parking brake.
3. Measure the height from the center of the headlamp to the ground.
Note: There may be an identifying mark on
the lens to help you locate the center of the
headlamp bulb.
4. Mark a horizontal reference line on the
vertical wall or screen that is a
minimum of
8 ft (2.4 m) long.
5. Switch the low beam headlamps on. 6.
There is a distinct change from light to
dark in the left-hand portion of the
headlamp beam pattern. Position the
top edge of this cut-off
2 in (5 cm)
below the horizontal reference line.

Note:
To avoid damaging the windshield,
lift the wiper blade a few inches off the
glass and place a cloth on the windshield
under the blade.
Note: Manually move the wiper blades to
the midway position.
Note: The windshield wiper blades are
different in length. The longer blade is on
the driver's side.
1. Disconnect the washer pipe from the wiper arm.
2. Press the release button on the top of the wiper arm where the blade
assembly attaches to the arm.
3. Pull the blade assembly away from the
arm, while rocking it from side to side
to help release it.
4. Keep the cloth in place to avoid the arm from hitting the windshield glass.
5. Install the new blade assembly and reconnect the washer pipe.
6. When complete, switch on the wipers and they will cycle back to the park
position when you switch them off.
Replace wiper blades at least once per
year for optimum performance. CHANGING A BULB
LED Lamps
All exterior and interior lamps on the GT
are LED.
These lamps operate at a high voltage.
Contact an authorized dealer if they fail.
