FORD 2010 Flex v.2 - Manual (Page 365)

Many of the world’s automakers approved the World-Wide Fuel Charter
that recommends gasoline specifications to provide improved
performance and emission control system protection for your vehicle.
Gasolines that meet the World-Wide Fuel Charter should be used when
available. Ask your fuel supplier about gasolines that meet the
World-Wide Fuel Charter.
Cleaner air
Ford endorses the use of reformulated “cleaner-burning” gasolines to
improve air quality, per the recommendations in the Choosing the right
fuel section.
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 Warning
lights and chimes in the Instrument Cluster chapter.
Refilling with a portable fuel container
With the Easy Fuel™ “no cap” fuel system, use the following directions
when filling from a portable fuel container:
WARNING: Do not insert the nozzle of portable fuel containers
or aftermarket funnels into the Easy 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 Easy
Fuel™ system with foreign objects. This could damage the fuel
system and its seal and cause injury to you or others.
