FORD 2011 E-450 v.2 - Manual (Page 185)

You may experience a decrease in peak performance when the engine is
cold when operating on E
85
ethanol.
Do not crank the engine for more than 10 seconds at a time as starter
damage may occur. If the engine fails to start, turn the key to off and
wait 30 seconds before trying again.
Do not use starting fluid such as ether in the air intake system. Such
fluid could cause immediate explosive damage to the engine and possible
personal injury.
If you should experience cold weather starting problems on E
85
ethanol,
and neither an alternative brand of E
85
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.
Guarding against exhaust fumes
Carbon monoxide is present in exhaust fumes. Take precautions to avoid
its dangerous effects.
WARNING: If you smell exhaust fumes inside your vehicle, have
your dealer inspect your vehicle immediately. Do not drive if you
smell exhaust fumes.
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.
ENGINE BLOCK HEATER (IF EQUIPPED)
An engine block heater warms the engine coolant which aids in starting
and allows the heater/defroster system to respond quickly. If your vehicle
is equipped with this system, your equipment includes a heater element
which is installed in your engine block and a wire harness which allows
the user to connect the system to a grounded 120 volt A/C electrical
source. The block heater system is most effective when outdoor
temperatures reach below 0°F (-18°C).
For flexible fuel vehicles, if operating with E
85
ethanol, an engine block
heater must be used if ambient temperature is below 0°F (-18°C).
