PRINCIPLE OF OPERATION
WARNINGS
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. 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. WARNINGS
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.

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 167).
• 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 167).
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
stop with the transmission in park (P) and
the engine running. This is necessary since
the vehicle ride height changes. You can
change between Normal, Wet and Sport
Drive Modes while the vehicle is in motion.

Front Lift
WARNING
Before using front lift, make sure the
area around your vehicle is free from
obstruction. Failure to follow this
instruction could result in personal injury
or death. Your vehicle has a front lift system to
provide additional front end clearance
when approaching a speed bump,
driveway ramp or another similar surface
where front end clearance could be a
concern.
The front lift button is located on the
center console. Press the button to lift the
front end of your vehicle. Press the button
again to return to normal ride height. A
warning indicator illuminates in the display
screen when the system is on. When you
shut the engine off, the car returns to
normal ride height. Remember to use the
front lift again when needed, for example
when backing out of a driveway.
Note:
The front lift feature only operates if
your vehicle is traveling under 25 mph
(40 km/h). If your vehicle exceeds this
speed, the system automatically returns
your vehicle to normal ride height.
Note: The front lift feature does not
function when in Track (T) or V-Max (V)
drive modes. Damper Comfort Mode
You can change the feel of the suspension
by pressing the damper comfort button on
the center console. An indicator illuminates
in the display screen when the system is
active. The comfort mode operates at
speeds up to
85 mph (137 km/h).
Pressing the damper comfort button
softens the suspension. Pressing the
button again returns the suspension to the
normal setting.
Note: The comfort mode selection does
not function when in Sport (S), Track (T)
or V-Max (V) drive modes.
Active Aerodynamics
The rear wing is a tri-state device designed
to operate automatically in either a
low-drag (down), high downforce (up) or
airbrake mode depending on the vehicle
demands.
The rear wing works in harmony with the
bi-state front splitter. The front splitter has
a raised leading edge so that the surfaces
underneath and immediately downstream
of it create a Venturi effect and lower the
air pressure creating downforce on the
front wheels. In normal (low-drag)
operation, the Venturi effect draws air
through ducts that connect the upper
surface of the splitter just below the
radiator intake. This reduces drag and
eliminates unnecessary front downforce.
When the rear wing moves out of the
low-drag position, and to compensate for

the front when loading the car onto a trailer
or a roll back. To operate the front lift, use
the switch in the console.
Note: The ground clearance on the car at
standard ride height is only 5 in (12 cm). Use
care when moving or loading the car to
make sure it does not bottom out.
Note: The vehicle doors swing both upward
and outward. At the full open position, the
top edge of the door is 67 in (170 cm) from
the ground and swings outward 26 in
(66 cm). Make sure you have the clearance
you need prior to opening the door.
The full undertrays of the vehicle are
carbon fiber, there are no tie down slots.
Use only over the tire straps to tie the car
down for transport.

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 204).
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. Note:
This procedure must be followed to
prevent over filling of the reservoir.
1. Start the engine and make sure that the steering wheel is at the straight
ahead position. Do not move the
steering wheel after this time.
2. Allow the engine to idle in Park for 2 minutes then shut the engine off.
3. After the engine has been off for 5 minutes, check the hydraulic fluid level
in the reservoir.
4. The MIN / MAX marks are on the front face of the reservoir. If the level is
above the MIN line on the reservoir DO
NOT add fluid. 5. If the level is below the MIN line, add
only enough fluid to bring the level to
a point between the MIN and MAX
lines.
6. DO NOT add fluid past the MAX line.
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze
protection. Failure to use washer fluid with
antifreeze protection in cold weather could
result in impaired windshield vision and
increase the risk of injury or accident. Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 204).
State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle ’s paint finish, wiper blades or
washer system.
FUEL FILTER
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.

WARNINGS
labels, then you should contact
your authorized dealer as soon as
possible. Use of any tire or wheel
not recommended by Ford can
affect the safety and performance
of your vehicle, which could result
in an increased risk of loss of
vehicle control, vehicle rollover,
personal injury and death. The use of
non-recommended tires and
wheels could cause steering,
suspension, axle, transfer case or
power transfer unit failure. If you
have questions regarding tire
replacement, contact your
authorized dealer as soon as
possible. To reduce the risk of serious
injury, when mounting
replacement tires and wheels, you
should not exceed the maximum
pressure indicated on the sidewall
of the tire to set the beads without
additional precautions listed
below. If the beads do not seat at
the maximum pressure indicated,
re-lubricate and try again. When inflating the tire for
mounting pressures up to
20 psi (1.38 bar) greater than the
maximum pressure on the tire
sidewall, the following
precautions must be taken to
protect the person mounting the
tire: •
Make sure that you have the
correct tire and wheel size.
• Lubricate the tire bead and
wheel bead seat area again.
• Stand at a minimum of
12 ft
(3.66 m) away from the wheel
and tire assembly.
• Use both eye and ear
protection. WARNINGS
For a mounting pressure
more than
20 psi (1.38 bar)
greater than the maximum
pressure, a Ford dealer or other
tire service professional should do
the mounting. Always inflate steel carcass
tires with a remote air fill with
the person inflating standing at a
minimum of
12 ft (3.66 m) away
from the wheel and tire assembly. Important: Remember to replace
the wheel valve stems when the
road tires are replaced on your
vehicle.
It is recommended that the two
front tires or two rear tires
generally be replaced as a pair.
The tire pressure sensors mounted
in the wheels (originally installed
on your vehicle) are not designed
to be used in aftermarket wheels.
