Flex Fuel Vehicle (Ffv) Fuel Fill Inlet; Choosing The Right Fuel - Ford 2010 Expedition Owner's Manual

Fuel Fill Inlet lamp or Check Fuel Fill Inlet message may not reset
immediately. It may take several driving cycles for the Check Fuel Fill
Inlet lamp or Check Fuel Fill Inlet 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 Check
Fuel Fill Inlet lamp or Check Fuel Fill Inlet message on may cause the
Service Engine Soon lamp to turn on as well.
WARNING: The fuel system may be under pressure. If you hear
a hissing sound near the fuel filler door (Easy Fuel™ "no cap"
fuel system), do not refuel until the sound stops. Otherwise, fuel may
spray out, which could cause serious personal injury.

The use of leaded fuel is prohibited by law and could damage your
vehicle.

compounds, including manganese-based additives.

powertrain damage, a loss of vehicle performance, and repairs may not
be covered under warranty.
