SAFETY PRECAUTIONS
WARNING: Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING: Fuels can cause serious
injury or death if misused or mishandled. WARNING:
Fuel may contain
benzene, which is a cancer-causing
agent. WARNING: When refueling always
shut the engine off and never allow
sparks or open flames near the fuel tank
filler valve. Never smoke or use a cell
phone while refueling. Fuel vapor is
extremely hazardous under certain
conditions. Avoid inhaling excess fumes.
Follow these guidelines when refueling:
• Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always switch the engine off before
refueling.
• Automotive fuels can be harmful or
fatal if swallowed. Fuel is highly toxic
and if swallowed can cause death or
permanent injury. If fuel is swallowed
immediately call a physician, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
apparent for hours. •
Avoid inhaling fuel vapors. Inhaling fuel
vapor can lead to eye and respiratory
tract irritation. In severe cases,
excessive or prolonged breathing of
fuel vapor can cause serious illness and
permanent injury.
• Avoid getting fuel in your eyes. If you
splash fuel in your eyes, immediately
remove contact lenses (if worn), flush
with water for 15 minutes and seek
medical attention. Failure to seek
proper medical attention could lead to
permanent injury.
• Fuels can be harmful if absorbed
through the skin. If you splash fuel on
your skin, clothing or both, promptly
remove contaminated clothing and
thoroughly wash your skin with soap
and water. Repeated or prolonged skin
contact causes skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing fuel vapors could cause an
adverse reaction, serious personal
injury or sickness. Immediately call a
physician if you experience any adverse
reactions.
FUEL QUALITY - MACH 1
Choosing the Right Fuel Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87.

WARNING: The fuel system may
be under pressure. If you hear a hissing
sound near the fuel filler inlet, do not
refuel until the sound stops. Otherwise,
fuel may spray out, which could cause
serious personal injury. WARNING:
Do not pry open the
fuel tank filler valve. This could damage
the fuel system. Failure to follow this
instruction could result in fire, personal
injury or death. WARNING: Do not remove the fuel
pump nozzle from its fully inserted
position when refueling. WARNING:
Stop refueling when
the fuel pump nozzle automatically
shuts off for the first time. Failure to
follow this will fill the expansion space
in the fuel tank and could lead to fuel
overflowing. WARNING:
Do not overfill the fuel
tank. The pressure in an overfilled tank
may cause leakage and lead to fuel spray
and fire. WARNING:
Wait at least five
seconds before removing the fuel pump
nozzle to allow any residual fuel to drain
into the fuel tank.
1. Fully open the fuel filler door.
2. Select the correct fuel pump nozzle for
your vehicle. 3. Insert the fuel pump nozzle up to the
first notch on the nozzle A. Keep the
fuel pump nozzle resting on the fuel
tank filler pipe. 4. Hold the fuel pump nozzle in position
B when refueling. Holding the fuel
pump nozzle in position A can affect
the flow of fuel and shut off the fuel
pump nozzle before the fuel tank is full.

Filling the Fuel Tank
For consistent results when refueling:
•
Switch the ignition off before fueling,
an inaccurate reading results if you
leave the engine running.
• Use the same fill rate,
low-medium-high, each time you fill
the tank.
• Allow no more than one automatic
shut-off when refueling.
Results are most accurate when the filling
method is consistent.
Calculating Fuel Economy
Your vehicle calculates fuel economy
figures through the trip computer average
fuel function. See Information Displays
(page 99).
The first
1,000 mi (1,600 km) of driving is
the break-in period of the engine. The
system obtains a more accurate
measurement after
2,000– 3,000 mi
(3,200–4,800 km).
Keep a record for at least one month and
record the type of driving, for example city
or highway. This provides an accurate
estimate of your vehicle ’s fuel economy
under current driving conditions. Keeping
records during summer and winter shows
how temperature impacts fuel economy.
Conditions Affecting Fuel Efficiency
• Carrying unnecessary weight in your
vehicle may reduce fuel economy.
• Avoid adding accessories that increase
aerodynamic drag to your vehicle such
as bug deflectors, car top carriers and
ski or bike racks.
• Remove empty roof racks and keep
windows shut at high speeds to reduce
wind resistance and fuel use. •
Check and adjust tire pressure
regularly. Underinflated tires increases
fuel consumption.
• Sudden acceleration and braking
degrade fuel efficiency. Drive smoothly
looking as far ahead as possible and
avoid short trips when possible.
• Fuel efficiency degrades with lower
temperatures.
• Comfort features use additional energy
and consume more fuel. Use AC and
other comfort features only when
necessary.
• Using fuel blended with alcohol may
increase fuel consumption.

time before line lock is released
automatically. If you exceed the time limit,
or another vehicle condition requires line
lock to release, the system safely
disengages and normal vehicle function
resumes.
Note:
If you apply the brake pedal while
line lock is engaged, line lock automatically
cancels and normal brake function resumes.
Performance Shift Indicator
The performance shift indicator displays
a row of colored lights that represent
engine RPM.
The performance shift indicator menu
allows you to:
• Choose whether the indicator is shown
on the windshield or information
display.
• Set a shift point within the allowable
RPM range in increments of 100.
• Enable or disable the associated shift
tone, based on the set shift point.
• Set the between off, change with drive
mode, tach, track and drag.
• Set the light intensity. The intensity
adjusts between day time and night
time. Start Option
Allows you to select the type of countdown
the information display shows before
starting an event.
Status Screen
Provides the status of your chosen
performance-related settings.
View/Clear Results
Allows you to view and clear the last and
saved results of the Acceleration Timer,
Brake Performance, and All Time Best
results.
Road Course Alignment
Recommendations
Note:
After your track day is complete,
return your car to the street alignment and
tire pressures.
Note: Using these wheel alignment settings
may cause excessive tire wear. Only use
these settings for racing or competitive
driving. Excessive tire wear is not covered
under the vehicle warranty.
If you plan to participate in road course
track days, we recommend the following
chassis settings for optimal tire wear and
handling performance.
All settings are at curb loading condition
full of fuel.

CLEANING THE EXTERIOR -
MACH 1
Washing Your Vehicle
Note: Do not use a touchless car wash or
any kind of commercial car wash equipment
with front splitter wickers installed.
Note: Always hand wash your vehicle if you
have vinyl stripes.
Do not drive your vehicle through an
automated, commercial car wash due to
the vehicle ’s low ground clearance and tire
width. Wash your vehicle by hand, or by
using a touchless commercial wash with
no mechanical tracks on the floor. Do not
use a power washer or high pressure wand.
To maintain proper cooling and
aerodynamics at high speeds, your vehicle
has heat exchangers integrated with the
front fascia designed to maximize
performance. Do not use a power washer
or high powered spray nozzle as damage
to the cooling fins could occur. Note:
For heavy accumulation of debris or
dirt, clean with a non-metallic soft bristle
car wash brush and warm soapy water as
needed.
CLEANING THE EXTERIOR
Wash your vehicle regularly with cool or
lukewarm water and a neutral pH
shampoo, we recommend Motorcraft
Detail Wash.
• Never use strong household detergents
or soap, for example dish washing or
laundry liquid. These products can
discolor and spot painted surfaces.
• Never wash your vehicle when it is hot
to the touch, or during strong or direct
sunlight.
• Dry your vehicle with a chamois or soft
terry cloth towel to eliminate water
spotting.
• Immediately remove fuel spillages, bird
droppings, insect deposits and road tar.
These may cause damage to your
vehicle ’s paintwork or trim over time.
We recommend Motorcraft Bug and
Tar Remover.
