FORD 2012 Expedition v.1 - Manual (Page 240)

If you should experience cold weather starting problems on E85 ethanol,
and neither an alternative brand of E85 ethanol nor an engine block
heater is available, the addition of unleaded gasoline to your tank will
improve cold starting performance. Your vehicle is designed to operate
on E
85
ethanol alone, unleaded gasoline alone, or any mixture of the two.
See Choosing the right fuel in the Maintenance and Specifications
chapter for more information on ethanol.
If the engine fails to start using the preceding instructions (flexible
fuel vehicles only)
1. Press and hold down the accelerator 1/3 to 1/2 way to floor, then
crank the engine.
2. When the engine starts, release the key, then gradually release the
accelerator pedal as the engine speeds up. If the engine still fails to start,
repeat Step 1.
Guarding against exhaust fumes
WARNING: If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
Important ventilating information
If the engine is idling while the vehicle is stopped for a long period of
time, open the windows at least 1 inch (2.5 cm) or adjust the heating or
air conditioning to bring in fresh air.
