Note: Including to the extent that any law pertaining to Event
Data Recorders applies to SYNC® or its features, please note the
following: Once 911 Assist (if equipped) is enabled (set ON), 911
Assist may, through any paired and connected cell phone, disclose
to emergency services that the vehicle has been in a crash
involving the deployment of an airbag or, in certain vehicles, the
activation of the fuel pump shut-off. Certain versions or updates
to 911 Assist may also be capable of being used to electronically
or verbally provide to 911 operators the vehicle location (such as
latitude and longitude), and/or other details about the vehicle or
crash or personal information about the occupants to assist 911
operators to provide the most appropriate emergency services. If
you do not want to disclose this information, do not activate the
911 Assist feature. See your SYNC® chapter for more
information.
Additionally, when you connect to Traffic, Directions and
Information (if equipped, U.S. only), the service uses GPS
technology and advanced vehicle sensors to collect the vehicle’s
current location, travel direction, and speed (“vehicle travel
information”), only to help provide you with the directions,
traffic reports, or business searches that you request. If you do
not want Ford or its vendors to receive this information, do not
activate the service. For more information, see Traffic, Directions
and Information, Terms and Conditions. See your SYNC® chapter
for more information.
CALIFORNIA PROPOSITION 65

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: The flow of fuel through a fuel pump nozzle can
produce static electricity. This can cause a fire if you are filling
an ungrounded container.
WARNING: Fuel ethanol and gasoline 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 filler neck. Never smoke
while refueling. Fuel vapor is extremely hazardous under certain
conditions. Care should be taken to avoid inhaling excess fumes.
WARNING: Do not remove the fuel pump nozzle from its full
inserted position when refueling.
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.

Note:Use of any fuel other than recommended fuel can cause
powertrain damage, impair the emission control system or cause loss of
vehicle performance. Any damage to the vehicle that is caused by the
use of fuel not recommended will not be covered under warranty.
Octane Recommendations
Regular unleaded gasoline with a
pump (R+M)/2 octane rating of 87
is recommended. Some stations
offer fuels posted as Regular with
an octane rating below 87,
particularly in high altitude areas. Fuels with octane levels below 87 are
not recommended. Premium fuel will provide improved performance and
is recommended for severe duty usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily under most driving conditions while you are using fuel
with the recommended octane rating, see your authorized dealer to
prevent any engine damage.
RUNNING OUT OF FUEL
Avoid running out of fuel because this situation may have an adverse
effect on powertrain components.
If you have run out of fuel:
• You may need to cycle the ignition from off to on several times after
refueling to allow the fuel system to pump the fuel from the tank to
the engine. On restarting, cranking time will take a few seconds longer
than normal.
• Normally, adding 1 gallon (3.8L) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8L) may be required.
• The service engine soon indicator may come on. For more information
on the service engine soon indicator, refer to the Instrument Cluster
chapter.
See Settings in theInstrument Cluster chapter for information on
calculating DTE (Distance to empty).

REFUELING
WARNING:Fuel vapor burns violently and a fuel fire can cause
severe injuries. To help avoid injuries to you and others:
• Read and follow all the instructions on the pump island.
• Turn off your engine when you are refueling.
• Do not smoke if you are near fuel or refueling your vehicle.
• Keep sparks, flames and smoking materials away from fuel.
• Stay outside your vehicle and do not leave the fuel pump unattended
when refueling your vehicle - this is against the law in some places.
• Keep children away from the fuel pump; never let children pump
fuel.
• Do not use personal electronic devices while refueling.
WARNING: Stop refueling after the fuel pump nozzle
automatically shuts off for the second time. Failure to follow this
will fill the expansion space in the fuel tank and could lead to fuel
overflowing.
Note: Wait at least 10 seconds before removing the fuel pump nozzle to
allow any residual fuel to drain into the fuel tank.
Use the following guidelines to avoid electrostatic charge build-up when
filling an ungrounded fuel container:
• Place approved fuel container on the ground.
• DO NOT fill a fuel container while it is in the vehicle (including the
cargo area).
• Keep the fuel pump nozzle in contact with the fuel container while
filling.
• DO NOT use a device that would hold the fuel pump handle in the fill
position.
Easy Fuel® “No Cap” Fuel System
WARNING: The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door, do not refuel until the
sound stops. Otherwise, fuel may spray out, which could cause serious
personal injury.

When fueling your vehicle:
1. Turn the engine off.
2. Open the fuel door by pulling the indent on the door.
3. Insert the fuel plug key (if equipped) into the locking plug and turn it
counterclockwise to unlock it.
4. Slowly insert the fuel filler nozzle fully into the fuel system, and leave
the nozzle fully inserted until you are done pumping.
5. After you are done pumping fuel, slowly remove the fuel filler
nozzle—allow about ten seconds after pumping fuel before removing the
fuel filler nozzle. This allows residual fuel to drain back into the fuel tank
and not spill onto the vehicle.
6. Reinstall the plug (if equipped) into the fuel fill inlet and turn the key
clockwise to lock.
Note:Do not overfill the tank or fuel spillage will occur.
If the fuel fill inlet was not properly closed, a Check Fuel Fill Inlet
message may appear on the information display. See the Information
Displays chapter for more information.
At the next opportunity, do the following:
1. Safely pull off the road.
2. Turn off the engine.
3. Open the fuel filler door and remove any visible debris from the fuel
fill opening.
4. Insert either the fuel fill nozzle or the fuel fill funnel provided with the
vehicle several times to dislodge any debris and/or allow the inlet to
close properly.
If this action corrects the problem, the message may not reset
immediately. It may take several driving cycles for the message to turn
off. A driving cycle consists of an engine start-up (after four or more
hours with the engine off) followed by city/highway driving. Continuing
to drive with the message on may cause the service engine soon lamp to
turn on as well.

FUEL SHUTOFF
WARNING: Failure to inspect and, if necessary, repair fuel leaks
after a collision may increase the risk of fire and serious injury.
Ford Motor Company recommends that the fuel system be inspected by
an authorized dealer after any collision.
In the event of a moderate to severe collision, this vehicle includes a fuel
pump shut-off feature that stops the flow of fuel to the engine. Not every
impact will cause a shut off.
Should your vehicle shut off after a collision, you may restart your
vehicle by doing the following:
1. Switch off the ignition.
2. Switch on the ignition.
3. Repeat Steps 1 and 2 to re-enable the fuel pump.
For vehicles equipped with a push button start system:
1. Press the START/STOP button to switch off the ignition.
2. Press the brake pedal and press the START/STOP button to start the
vehicle.
3. Remove your foot from the brake pedal and press the START/STOP
button to switch off the ignition.
4. You can either attempt to start the engine by pressing the brake pedal
and the START/STOP button, or switch on the ignition only by pressing
the START/STOP button without pressing the brake pedal. Both ways
re-enable the fuel system.
Note: When you try to restart your vehicle after a fuel shutoff, the
vehicle makes sure that various systems are safe to restart. Once your
vehicle determines that the systems are safe, then the vehicle will allow
you to restart.
Note: In the event that your vehicle does not restart after your third
attempt, contact an authorized dealer.
