If you connect a cell phone to the system,
the system creates a profile that links to
that cell phone. The cell phone profile
enables more mobile features and efficient
operation. The profile contains, for
example, data from your phonebook, read
and unread text messages and call history,
including history of calls when your cell
phone was not connected to the system.
If you connect a media device, the system
creates and retains a media device index
of supported media content. The system
also records a short diagnostic log of
approximately 10 minutes of all recent
system activity.
The cell phone profile, media device index
and diagnostic log remain in your vehicle
unless you delete them and are generally
accessible only in your vehicle when you
connect your cell phone or media device.
If you no longer plan to use the system or
your vehicle, we recommend you use the
master reset function to erase the stored
information. See Settings (page 543).
System data cannot be accessed without
special equipment and access to your
vehicle's module.
For additional information about our
privacy policy, refer to your local Ford
website.

Engine Oil Pressure Gauge
Indicates engine oil pressure. The needle
should stay in the normal operating range
(between L and H). If the needle falls
below the normal range, stop your vehicle,
turn off the engine and check the engine
oil level. Add oil if needed. If the oil level is
correct, have your vehicle checked by an
authorized dealer.
Engine Coolant Temperature
Gauge
WARNING: Do not remove the
coolant reservoir cap when the engine is
on or the cooling system is hot. Wait 10
minutes for the cooling system to cool
down. Cover the coolant reservoir cap
with a thick cloth to prevent the
possibility of scalding and slowly remove
the cap. Failure to follow this instruction
could result in personal injury.
Indicates engine coolant temperature. At
normal operating temperature, the level
indicator will be in the normal range. If the
engine coolant temperature exceeds the
normal range, stop your vehicle as soon as
safely possible, switch off the engine and
let the engine cool.
Fuel Gauge
Note: The fuel gauge may vary slightly
when your vehicle is moving or on a slope.
The fuel gauge indicates about how much
fuel is in the fuel tank.
The arrow adjacent to the fuel pump
symbol indicates on which side of your
vehicle the fuel filler door is located. Low Fuel Reminder
A low fuel level reminder displays and
sounds when the distance to empty
reaches
75 mi (120 km) to empty for
MyKey, and at 50 mi (80 km), 25 mi
(40 km), 10 mi (20 km) and 0 mi (0 km)
for all vehicle keys.
Note: The low fuel reminder can appear at
different fuel gauge positions depending on
fuel economy conditions. This variation is
normal.
Transmission Fluid Temperature
Gauge
Indicates transmission fluid temperature.
At normal operating temperature, the level
indicator will be in the normal range. If the
transmission fluid temperature exceeds
the normal range, stop the vehicle as soon
as safely possible and verify the airflow is
not restricted such as snow or debris
blocking airflow through the grill. Also,
higher than normal operating temperature
can be caused by special operation
conditions (i.e. snowplowing, towing or
off-road use). Operating the transmission
for extended periods with the gauge in the
higher than normal area may cause
internal transmission damage. You need
to alter the severity of your driving
conditions to lower the transmission
temperature into the normal range. If the
gauge continues to show high
temperatures, see an authorized dealer.

During refueling, it is possible for
you to pump
water-contaminated diesel fuel
into your fuel tank. Your vehicle ’s fuel
system is equipped with a fuel filter and
water separator to remove water from the
fuel. The water in fuel indicator illuminates
when the fuel and water separator has a
significant quantity of water in it and
requires immediate draining.
If the water in fuel indicator illuminates
when the engine is running, stop your
vehicle as soon as safely possible, shut off
the engine, then drain the fuel and water
separator. See Fuel Quality (page 187).
Allowing water to stay in the fuel system,
after the water in fuel indicator illuminates,
could result in extensive damage or failure
of the fuel injection system.
Note: Do not drain the fuel and water
separator while the engine is running. Air will
enter into the fuel system causing the engine
not to operate properly.

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:
Automotive fuels can
cause serious injury or death if misused
or mishandled. WARNING:
Flow of fuel through a
fuel pump nozzle can produce static
electricity. This can cause a fire if you are
filling an ungrounded fuel container. 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.
Observe the following guidelines when
handling automotive fuel:
• Extinguish all smoking materials and
any open flames before refueling your
vehicle.
• Always turn off the vehicle before
refueling. •
Automotive fuels can be harmful or
fatal if swallowed. Fuel such as
gasoline is highly toxic and if
swallowed can cause death or
permanent injury. If fuel is swallowed,
call a physician immediately, even if no
symptoms are immediately apparent.
The toxic effects of fuel may not be
visible for hours.
• Avoid inhaling fuel vapors. Inhaling too
much fuel vapor of any kind 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 liquid in your eyes. If
fuel is splashed in the eyes, 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 also be harmful if absorbed
through the skin. If fuel is splashed on
the skin, clothing or both, promptly
remove contaminated clothing and
wash skin thoroughly with soap and
water. Repeated or prolonged skin
contact with fuel liquid or vapor causes
skin irritation.
• Be particularly careful if you are taking
Antabuse or other forms of Disulfiram
for the treatment of alcoholism.
Breathing gasoline vapors could cause
an adverse reaction, serious personal
injury or sickness. If fuel is splashed on
the skin, wash the affected areas
immediately with plenty of soap and
water. Consult a physician immediately
if you experience any adverse reactions.

FUEL QUALITY - E85
Choosing the Right Fuel - Flex Fuel
Vehicles
Flex fuel vehicles have one of the following
identifiers:
•
Yellow fuel filler cap.
• Yellow bezel around the fuel filler inlet.
• Yellow fuel filler housing.
• Yellow E85 label on the fuel tank filler
door. Your vehicle is designed to operate on
regular unleaded gasoline with a minimum
pump (R+M)/2 octane rating of 87 or
regular unleaded gasoline blended with a
maximum of 85% ethanol (E85).
Some fuel stations, particularly those in
high altitude areas, offer fuels posted as
regular unleaded gasoline with an octane
rating below 87. The use of these fuels
could result in engine damage that will not
be covered by the vehicle warranty.
For best overall vehicle and engine
performance, premium fuel with an octane
rating of 91 or higher is recommended. The
performance gained by using premium fuel
is most noticeable in hot weather as well
as other conditions, for example when
towing a trailer. See Towing (page 282).Do not be concerned if the engine
sometimes knocks lightly. However, if the
engine knocks heavily while using fuel with
the recommended octane rating, contact
an authorized dealer to prevent any engine
damage.
We recommend Top Tier detergent
gasolines, where available to help minimize
engine deposits and maintain optimal
vehicle and engine performance. For
additional information, refer to
www.toptiergas.com.
Note:
Use of any fuel for which the vehicle
was not designed can impair the emission
control system, cause loss of vehicle
performance, and cause damage to the
engine which may not be covered by the
vehicle Warranty.
Do not use:
• Diesel fuel.
• Fuels containing kerosene or paraffin.
• Fuels containing more than 85%
ethanol or E100 fuel.
• Fuels containing methanol.
• Fuels containing metallic-based
additives, including manganese-based
compounds.
• Fuels containing the octane booster
additive, methylcyclopentadienyl
manganese tricarbonyl (MMT).
• Leaded fuel, using leaded fuel is
prohibited by law.
The use of fuels with metallic compounds
such as methylcyclopentadienyl
manganese tricarbonyl (commonly known
as MMT), which is a manganese-based
fuel additive, will impair engine
performance and affect the emission
control system.

Switching Between E85 and
Gasoline
We do not recommend repeatedly
alternating between E85 and gasoline. If
you switch from using E85 to gasoline, or
from gasoline to E85, add as much fuel as
possible, at least half a tank. Drive your
vehicle immediately for a minimum of 5 mi
(8 km) to allow it to adapt to the change
in ethanol concentration. If you use E85
exclusively, we recommend that you fill
the fuel tank with regular unleaded
gasoline at each scheduled oil change.

exported to non- ultra low sulfur diesel fuel
markets will need to be retrofitted at the
customer
’s expense using Ford authorized
dealer service parts in order to be reliably
operated on non- ultra low sulfur diesel
fuel.
Biodiesel WARNING: Do not mix diesel with
gasoline, gasohol or alcohol. This could
cause an explosion.
Note: Do not use home heating oil,
agricultural fuel, raw fats and oils, waste
cooking greases, biodiesel greater than 20%
or any diesel not intended for highway use.
Damage to the fuel injection system, engine
and exhaust catalyst, and diesel particulate
filter can occur if you use an improper fuel.
Red dye is used to identify fuels intended
for agricultural and non-highway use.
You may operate your vehicle on diesel
fuels containing up to 20% biodiesel, also
known as B20.
Biodiesel fuel is a chemically converted
product from renewable fuel sources, such
as vegetable oils, animal fats and waste
cooking greases.
To help achieve acceptable engine
performance and durability when using
biodiesel in your vehicle:
• Confirm the biodiesel content of the
fuel to be B20 (20% biodiesel) or less
• Only use biodiesel fuel of good quality
that complies with industry standards
• Follow the recommended service
maintenance intervals
See General
Maintenance Information (page 565). •
Do not store biodiesel fuel in the fuel
tank for more than 1 month
• Consider changing brands or reducing
biodiesel content if you have cold
temperature fuel gelling issues or a
frequent LOW FUEL PRESSURE
message appearing
Use of biodiesel in concentrations greater
than 20% may cause damage to your
vehicle, including engine and/or exhaust
after-treatment hardware (exhaust
catalyst and particulate filter) failures.
Concentrations greater than 20% can also
cause fuel filter restrictions that may result
in a lack of power or damage to fuel
system components, including fuel pump
and fuel injector failures.
We recommend SAE 5W-40 oil for fuels
with greater than 5% biodiesel (B5). For
more information about oil change
intervals and other maintenance when
operating on biodiesel
See Special
Operating Conditions Scheduled
Maintenance
(page 574).
Look for a label on the fuel pump to
confirm the amount of biodiesel contained
in a diesel fuel. Biodiesel content is often
indicated with the letter B followed by the
percent of biodiesel in the fuel. For
example, B20 indicates a fuel containing
20% biodiesel. Ask the service station
attendant to confirm the biodiesel content
of a diesel fuel if you do not see a label on
the fuel pump.
Biodiesel fuels degrade more easily than
diesel fuels not containing biodiesel and
should not be stored in the fuel tank for
more than 1 month. If you plan to park or
store your vehicle for more than 1 month,
then you should empty your vehicle fuel
tank of biodiesel fuel. You should fill the
tank with a pure petroleum-based diesel
fuel and run your vehicle for a minimum of
30 minutes.
