Note:
If the system activates, the brake
pedal may pulse and may travel further.
Maintain pressure on the brake pedal. You
may also hear a noise from the system. This
is normal.
ELECTRIC PARKING BRAKE WARNING: Always set the parking
brake and leave your vehicle with the
transmission in park (P).
The electric parking brake operates with
the switch in the center console.
Note: When you apply the electric parking
brake in certain conditions, for example, on
a steep hill, the electric parking brake may
reapply the brakes within three to ten
minutes.
Note: You may notice various noises when
you apply and release the electric parking
brake. This is normal and no cause for
concern.
Applying the Electric Parking
brake WARNING:
Applying the electric
parking brake while moving will result in
the engagement of the anti-lock braking
system. Do not use the electric parking
brake system when the vehicle is moving
unless the normal brake system is unable
to stop the vehicle. WARNING: With the exception of
emergency conditions (for example, the
brake pedal is broken or is blocked), do
not apply the electric parking brake while
the vehicle is moving. On bends, or poor
road surfaces or weather conditions,
emergency braking can cause the vehicle
to skid out of control or off the road. Note:
The brake system warning lamp
lights during an electric parking brake apply.
If the brake system warning lamp flashes
and continues to flash, there could be a
problem with your electric parking brake.
See your authorized dealer.
Note: The brake system warning lamp
illuminates for ten seconds if you switch the
ignition off after you apply the electric
parking brake, or you apply the electric
parking brake after you switch the ignition
off.
Note: When you switch the engine off, the
electric parking brake applies. Pull the switch up to apply the electric
parking brake.
The brake system warning lamp flashes
for about two seconds and then
illuminates to confirm that you have
applied the electric parking brake. See
Information Displays
(page 69).
If you apply the electric parking brake when
your vehicle is moving, the brake system
warning lamp illuminates and a warning
chime sounds. See Information Displays
(page
69).
If your vehicle speed is above
4 mph
(6 km/h), the braking force is applied as
long as you pull the switch. Releasing or
pressing the switch or pressing the
accelerator pedal will stop the braking
force.

HILL START ASSIST
WARNING: The system does not
replace the parking brake. When you
leave your vehicle, always apply the
parking brake. WARNING:
You must remain in
your vehicle when the system turns on.
At all times, you are responsible for
controlling your vehicle, supervising the
system and intervening, if required.
Failure to take care may result in the loss
of control of your vehicle, serious
personal injury or death. WARNING:
The system turns off
if there is a malfunction or if you
excessively rev the engine.
The system makes it easier to pull away
when your vehicle is on a slope without the
need to use the parking brake.
When the system is active, your vehicle
remains stationary on the slope for two to
three seconds after you release the brake
pedal. This allows you time to move your
foot from the brake to the accelerator
pedal. The brakes release automatically
once the engine develops sufficient torque
to prevent your vehicle from rolling down
the slope. The system activates
automatically on any slope that causes
significant vehicle rollback.
Note: There is no warning lamp to indicate
the system is either on or off.
Using Hill Start Assist
1. Press the brake pedal to bring your vehicle to a complete standstill. Keep
the brake pedal pressed.
2. If the sensors detect that your vehicle is on a slope, the system activates
automatically. 3. When you remove your foot from the
brake pedal, your vehicle will remain
on the slope without rolling away for
about two or three seconds. This hold
time automatically extends if you are
in the process of driving off.
4. Drive off in the normal manner. The brakes release automatically.

PRINCIPLE OF OPERATION
WARNING: Vehicle modifications
involving braking system, aftermarket
roof racks, suspension, steering system,
tire construction and wheel and tire size
may change the handling characteristics
of your vehicle and may adversely affect
the performance of the electronic
stability control system. In addition,
installing any stereo loudspeakers may
interfere with and adversely affect the
electronic stability control system. Install
any aftermarket stereo loudspeaker as
far as possible from the front center
console, the tunnel, and the front seats
in order to minimize the risk of interfering
with the electronic stability control
sensors. Reducing the effectiveness of
the electronic stability control system
could lead to an increased risk of loss of
vehicle control, vehicle rollover, personal
injury and death. WARNING:
Remember that even
advanced technology cannot defy the
laws of physics. It's always possible to
lose control of a vehicle due to
inappropriate driver input for the
conditions. Aggressive driving on any
road condition can cause you to lose
control of your vehicle increasing the risk
of personal injury or property damage.
Activation of the electronic stability
control system is an indication that at
least some of the tires have exceeded
their ability to grip the road; this could
reduce the operator's ability to control
the vehicle potentially resulting in a loss
of vehicle control, vehicle rollover,
personal injury and death. If your
electronic stability control system
activates, SLOW DOWN. WARNING:
The stability and
traction control light illuminates steadily
if the system detects a failure. Make sure
you did not manually disable the traction
control system using the information
display controls or the switch. If the
stability control and traction control light
is still illuminating steadily, have the
system serviced by an authorized dealer
immediately. Operating your vehicle with
the traction control disabled could lead
to an increased risk of loss of vehicle
control, vehicle rollover, personal injury
and death.
The stability and traction control systems
help you to avoid drive wheel spin and loss
of traction. The system automatically
turns on each time you switch the ignition
on.
If a fault occurs in either the stability
control or the traction control system, you
may experience the following conditions:
• The stability and traction control light
illuminates steadily.
• The stability control and traction
control systems do not enhance your
vehicle's ability to maintain traction of
the wheels.
If a driving condition activates either the
stability control or the traction control
system you may experience the following
conditions:
• The stability and traction control light
flashes.
• Your vehicle slows down.
• Reduced engine power.
• A vibration in the brake pedal.

•
The brake pedal is stiffer than usual.
• If the driving condition is severe and
your foot is not on the brake, the brake
pedal may move as the system applies
higher brake force.
The stability and traction control systems
have several features built into it to help
you maintain control of your vehicle:
AdvanceTrac ™ Electronic
Stability Control
The system enhances your vehicle ’s ability
to prevent skids or lateral slides by
applying brakes to one or more of the
wheels individually and, if necessary,
reducing engine power.
Traction Control
The system enhances your vehicle ’s ability
to maintain traction of the wheels by
detecting and controlling wheel spin.
Traction control settings on your vehicle
are integrated into the AdvanceTrac
Stability Control system. USING STABILITY CONTROL
AdvanceTrac
™ Electronic
Stability Control
The system automatically turns on each
time you switch the ignition on. You can
also use the stability control button on the
center console to adjust the operation of
the AdvanceTrac stability control system.
AdvanceTrac electronic stability control is
disabled when the transmission is in
reverse (R).
The amount of change you can make to
the AdvanceTrac stability control system
depends on the Drive Mode you have
selected.

B If your vehicle begins to slide, the system
applies the brakes to individual wheels
and, when needed, reduces engine power
at the same time. If the wheels spin when
accelerating on slippery or loose surfaces,
the system reduces engine power in order
to increase traction.
System Indicator Lights and Messages The stability and traction control
light temporarily illuminates on
engine start-up and flashes:
• When a driving condition activates
either of the systems.
• If a problem occurs in either of the
systems. The stability and traction control
off light temporarily illuminates
on engine start-up and stays on
when you adjust the operation of the
AdvanceTrac stability control system. The
amount of change you can make to the
AdvanceTrac stability control system
depends on the drive mode you have
selected. The chart found earlier in this
section shows how much you can change
the stability control and traction control
for each drive mode.

STEERING
To help prevent damage to the power
steering system:
•
Never hold the steering wheel at its
furthest turning points (until it stops)
for more than three to five seconds
when the engine is running.
• Do not operate the vehicle with a low
hydraulic fluid level. See Power
Steering Fluid Check (page 159).
• Some noise is normal during operation.
If excessive, check for low hydraulic
fluid level before seeking service by
your dealer.
• Heavy or uneven efforts may be caused
by low hydraulic fluid. Check for low
hydraulic fluid level before seeking
service by your dealer.
• Do not over fill the hydraulic fluid as
this may result in leaks from the
reservoir. See
Power Steering Fluid
Check (page 159).
If the power steering system breaks down
(or if the engine is off), you can manually
steer the vehicle, but it takes more effort.
If the steering wanders or pulls, check for:
• An improperly inflated tire.
• Uneven tire wear.
• Loose or worn suspension
components.
• Loose or worn steering components.
• Improper vehicle alignment.
A high crown in the road or high crosswinds
may also make the steering seem to
wander or pull. DRIVE MODE CONTROL
Drive Mode Selection
Your vehicle has five selectable drive
modes that deliver an enhanced driving
experience through a suite of sophisticated
electronic vehicle systems. In response to
vehicle use and driving conditions, the
selection of the drive mode optimizes
handling and powertrain response. This
provides a single location to control
multiple systems performance settings.
Using Selectable Drive Modes
To change the drive mode setting, use the
rotary switch on the left side of the steering
wheel.
Note:
To engage or disengage Track or
V-Max Drive Modes, the car must be at a

BREAKING-IN
You need to break in new tires for
approximately 300 mi (480 km). During
this time, your vehicle may exhibit some
unusual driving characteristics.
You should not drive your Ford GT
aggressively for the first
600 mi
(1,000 km) of vehicle operation. This will
allow for proper break in of the powertrain
and braking systems.
For the first 600 miles (1,000 km):
• Do not apply high load at low engine
speed.
• Do not drive the vehicle at a sustained
high-speed, high load.
• Avoid driving the vehicle at full throttle.
• Drive the vehicle at varying road and
engine speeds.
• Do not drive in competition and race
track conditions.
• Do not use launch control.
• If you are going to use the vehicle on
the race track right after break in,
change the oil after break in.
Cold Engine Operation
The design of your Ford GT restricts engine
power and RPM when the engine is cold.
The engine RPM and power output will be
reduced until the engine reaches full
operating temperature.
Hot Engine Shut down
You should allow your Ford GT engine to
cool down for a few minutes prior to shut
down after high speed or high performance
driving. Allowing the engine to run at light
loads and or idle for a few minutes will
reduce overall engine oil and coolant
temperatures. DRIVING THROUGH WATER WARNING:
Do not drive through
flowing or deep water as you may lose
control of your vehicle.
Note: Driving through standing water can
cause vehicle damage.
Note: Engine damage can occur if water
enters the air filters.
Before driving through standing water,
check the depth. Do not drive through
water that is higher than the sidewall of
the front tire. If the water is up onto the
wheel, do not proceed. When driving
through a puddle, drive slowly to avoid
splashing the water into the engine air
intake. When driving through standing water, drive
very slowly and do not stop your vehicle.
Your brake performance and traction may
be limited.
After driving through water and as soon as
it is safe to do so:
•
Lightly press the brake pedal to dry the
brakes and to check that they work.
• Check that the horn works.
