Rear Power Distribution Box 1
The rear power distribution box is in the
engine compartment. See Under Hood
Overview (page 159). It has high-current
fuses that protect your vehicle's main
electrical systems from overloads. These
are in the right-hand side of the engine
compartment behind an access door in the
engine surround panel. If you need to
replace these high-current fuses, see an
authorized dealer. If you disconnect and reconnect the
battery, you need to reset some features.
See Changing the 12V Battery (page 167

ENGINE OIL CHECK
Note: Use a thick cloth to protect your hand
when removing the oil tank cap and dipstick.
To check the engine oil level consistently
and accurately, do the following:
1. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature (Coolant
temperature of 190°F (87.7°C) or
higher).
3. Turn the engine off and wait two to three minutes.
4. Make sure that your vehicle is on level ground.
5. Open the rear hatch. See
Opening
and Closing the Hood (page 157).
6. Unscrew the oil tank cap to remove the
dipstick and wipe it with a clean,
lint-free cloth. See
Under Hood
Overview (page 159). 7. Replace the cap and dipstick and
remove it again to check the oil level.
See
Engine Oil Dipstick (page 160).
8. Make sure that the oil level is between
the minimum and the maximum marks.
If the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 207).
9. If the oil level is correct, replace the cap
and dipstick and make sure it is fully
tightened.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,000 mi (5,000 km)
.
Note: High performance vehicles tend to
be driven in such a way the engine
experiences high speed and high load. As a
result, some oil consumption could occur
between oil changes. We recommend that
you check the oil level on a regular basis.
Adding Engine Oil WARNING:
Do not remove the
filler cap when the engine is running. WARNING:
Do not add engine
oil when the engine is hot. Failure to
follow this instruction could result in
personal injury.
Note: Use a thick cloth to protect your hand
when removing the oil tank cap and dipstick.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.

How Fail-Safe Cooling Works
If the engine begins to overheat, the
coolant temperature gauge moves toward
the red zone:
A warning lamp illuminates and
a message may appear in the
information display.
If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
When this occurs, your vehicle still
operates, however:
• Engine power is limited.
• The air conditioning system turns off.
Continued operation increases the engine
temperature, causing the engine to
completely shut down. Your steering and
braking effort increases in this situation.
When the engine temperature cools, you
can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.
When Fail-Safe Mode Is Activated WARNING: Fail-safe mode is for
use during emergencies only. Operate
your vehicle in fail-safe mode only as
long as necessary to bring your vehicle
to rest in a safe location and seek
immediate repairs. When in fail-safe
mode, your vehicle will have limited
power, will not be able to maintain high-speed operation, and may
completely shut down without warning,
potentially losing engine power, power
steering assist, and power brake assist,
which may increase the possibility of a
crash resulting in serious injury.
WARNING:
Never remove the
coolant reservoir cap when the engine is
running or hot.
Your vehicle has limited engine power
when in the fail-safe mode, drive your
vehicle with caution. Your vehicle does not
maintain high-speed operation and the
engine may operate poorly.
Remember that the engine is capable of
automatically shutting down to prevent
engine damage. In this situation:
1. Pull off the road as soon as safely possible and switch the engine off.
2. Contact the Ford GT Concierge to obtain assistance.
See About This
Manual (page 5).
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level. If the coolant level is at or below the minimum mark,
add prediluted coolant immediately.
5. When the engine temperature cools, you can re-start the engine. Have your
vehicle checked as soon as possible to
minimize engine damage.
Note: Driving your vehicle without repair
increases the chance of engine damage.

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. WARNING:
Do not allow the
fluid to touch your skin or eyes. If this
happens, rinse the affected areas
immediately with plenty of water and
contact your physician. WARNING: A fluid level between
the
MAX and MIN lines is within the
normal operating range and there is no
need to add fluid. A fluid level not in the
normal operating range could
compromise the performance of the
system. Have your vehicle checked
immediately. To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.
Only use fluid that meets Ford
specifications. See
Capacities and
Specifications (page 207).
POWER STEERING FLUID
CHECK
The hydraulic fluid reservoir is under the
hood. The fluid is used for power steering,
active aerodynamics and the active
hydraulic suspension. Keep the fluid level
between MIN and MAX marks as shown
on the reservoir. 166

Because your vehicle
’s engine is
electronically controlled by a computer,
some control conditions are maintained
by power from the battery. When the
battery is disconnected or a new battery
is installed, the engine must relearn its idle
and fuel trim strategy for optimum
driveability and performance.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your vehicle.
5. Run the engine until it reaches normal operating temperature. As the engine
is warming up, complete the following:
Reset the clock. See Audio System
(page 218). Reset the radio station
presets. See Audio System (page 218).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim and
fuel trim strategy.
Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel
trim strategy.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
Battery Charger and Maintainer
If you plan to have your GT parked or in
storage for more than two weeks without
driving it, connect the Li-Ion compatible
battery charger and maintainer provided.
There are two methods to connect the
charger: Method 1: Rear Hatch Storage
Compartment Power Point
Your Ford GT has a 12V power point in the
rear hatch storage area that allows you to
conveniently plug in to charge and
maintain your battery.
Note:
You can only the use the hatch
storage power point for battery charging.
The one inside the passenger compartment
on the side of the center console will not
work for this purpose. 1. Locate and open the cap covering the
power point.
2. Insert the provided charger plug in to the power point.
3. Connect the charger to the wall socket.
4. Disconnect the charger from the wall socket before disconnecting the cigar
plug.
Method 2: Under Hood Jump Start
Posts
You can also connect the battery charger
to the posts underneath the front hood for
jump starting the vehicle. The charger
connects simply to the jump start positive
(+) and negative (-) posts as shown in the
following illustration.
