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.

Octane Recommendations
3.5L V6 EcoBoost, 3.7L V6 TiVCT and 2.0L I4 EcoBoost Engines
We recommend regular unleaded gasoline with a pump (R+M)/2 octane
rating of 87. Some stations offer fuels posted as regular with an octane
rating below 87, particularly in high altitude areas. We do not recommend
fuels with octane levels below 87. To provide improved performance, we
recommend premium fuel for severe duty usage such as trailer tow.
Do not be concerned if your engine sometimes knocks lightly. However, if
it knocks heavily while you are using fuel with the recommended octane
rating, contact an 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, crank time will be a few seconds longer
than normal. With keyless ignition, just start the engine. Crank time
will be longer than usual.
•Normally, adding 1 gallon (3.8 liters) of fuel is enough to restart the
engine. If the vehicle is out of fuel and on a steep grade, more than
1 gallon (3.8 liters) may be required.
•The service engine soon indicator may come on. For more information
on the service engine soon indicator, seeWarning Lamps and
Indicatorsin theInstrument Clusterchapter.
Refilling with a Portable Fuel Container
WARNING:Do not insert the nozzle of a portable fuel container
or aftermarket funnel into the capless fuel system. This could
damage the fuel system and its seal, and may cause fuel to run onto the
ground instead of filling the tank, which could result in serious personal
injury.
WARNING:Do not try to pry open or push open the capless fuel
system with foreign objects. This could damage the fuel system
and its seal and cause injury to you or others.
