You may notice a reduction in vehicle
speed caused by reduced engine power in
order to manage the engine coolant
temperature. Your vehicle may enter this
mode if certain high-temperature and
high-load conditions take place. The
amount of speed reduction depends on
vehicle loading, slope and ambient
temperature. If this occurs, there is no
need to pull off the road. You can continue
to drive your vehicle.
The air conditioning may automatically
turn on and off during severe operating
conditions to protect the engine from
overheating. When the coolant
temperature decreases to the normal
operating temperature, the air conditioning
turns on.
If the coolant temperature gauge moves
fully into the red zone, or if the coolant
temperature warning or service engine
soon messages appear in your information
display, do the following:
1. Pull off the road as soon as safely
possible and shift the transmission into
park (P).
2. Leave the engine running until the coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature
does not drop, follow the remaining
steps.
3. Switch the engine off and wait for it to
cool. Check the coolant level.
4. If the coolant level is at or below the minimum mark, add prediluted coolant
immediately.
5. If the coolant level is normal, restart the engine and continue. AUTOMATIC TRANSMISSION
FLUID CHECK
If required, have an authorized dealer check
and change the transmission fluid at the
correct service interval. See Scheduled
Maintenance (page 279).
The automatic transmission does not have
a transmission fluid dipstick.
Refer to your scheduled maintenance
information for scheduled intervals for fluid
checks and changes. Your transmission
does not consume fluid. However, if the
transmission slips, shifts slowly or if you
notice a sign of leaking fluid, contact an
authorized dealer.
Do not use supplemental transmission
fluid additives, treatments or cleaning
agents. The use of these materials may
affect transmission operation and result
in damage to internal transmission
components.
BRAKE FLUID CHECK WARNING:
Do not use any fluid
other than the recommended brake fluid
as this will reduce brake efficiency. Use
of incorrect fluid could result in the loss
of vehicle control, serious personal injury
or death. WARNING:
Only use brake fluid
from a sealed container. Contamination
with dirt, water, petroleum products or
other materials may result in brake
system damage or failure. Failure to
adhere to this warning could result in the
loss of vehicle control, serious personal
injury or death.

Operating at High Speeds and on
Track Days
Your vehicle is capable of sustained high
speeds and track day driving. Follow the
guidelines for breaking in the tires and
powertrain before operating your vehicle
at high speeds or on a track. See
Breaking-In (page 131).
Note: Obey all traffic laws and only operate
your vehicle at locations designed to do so
safely.
Note: For a detailed description of what
your vehicle's New Limited Warranty covers,
see the Ford GT Warranty Guide provided
to you along with your owner's manual.
Before operating your vehicle at high
speeds, follow these guidelines:
Overall Vehicle Preparation:
• Inspect wheels and tires for wear and
damage. Replace any damaged wheels
or tires.
• Torque the wheel lug nuts to the proper
specification:
150 lb.ft (204 Nm).
• Inspect all aerodynamic grilles and
cooling system components for
damage. Make sure there is no debris
or non-factory installed protective
films or equipment that could obstruct
airflow.
• Verify your tires have the correct tire
pressure. See the section that follows
for tire pressure specifications.
• Do not operate your vehicle at high
speeds while carrying cargo. Brake System Preparation:
•
Your vehicle has carbon ceramic brake
rotors that require extra care and
inspection methods including
measuring their weight and reviewing
the surface condition.
• Inspect the brake system for wear or
damage. Replace worn or below
specification brake pads, rotors or
cooling hoses. Make sure that the cross
drilling holes in the rotors are open and
free of debris.
• Prior to track use, replace the brake
fluid with fresh Motorcraft/Ford DOT
4 LV High Performance Brake Fluid or
other DOT compliant fluid with a dry
boiling point greater than
500°F
(260°C) from a sealed container. Do
not use silicone or DOT 5 brake fluids.
Powertrain Preparation:
• Make sure the engine oil, coolant,
transmission fluids and hydraulic
system fluid have received proper
maintenance, are clean and are at the
appropriate capacity.
• Allow the powertrain to warm up and
reach normal operating temperature.
Your vehicle has electronic controls to
reduce power or limit engine RPM to
reduce powertrain temperatures if
required.
• Regularly check the engine oil level
during the event. Maintain the engine
oil level at or near the max mark on the
engine oil dipstick.
See Engine Oil
Check (page 157).
Note: To obtain service, please contact the
Ford GT Concierge and they will advise you
of the nearest Certified Ford GT Service
Dealership.

WHAT IS LAUNCH CONTROL
Note:
Only use this feature in a controlled
environment, such as a track. Launch control
is not for use in normal driving.
Note: Launch control is not available when
in the Wet drive mode.
Your vehicle has a launch control feature
that uses clutch and engine controls to
reduce wheel spin or slip on a hard
acceleration from a standing start.
To operate launch control, your vehicle
must meet the following conditions:
• You must be in any drive mode other
than Wet drive mode.
• You must close the doors, front hood
and rear hatch.
• Your vehicle should be on a level
surface.
• You must disengage the electric park
brake.
• You must be at a complete stop with
the brake pedal applied and the
