FORD 2015 Fusion Hybrid - Manual (Page 151)

Using the Engine Block Heater
The engine block heater plug is located in
a housing in the left fog lamp bezel. Open
the hinged, circular door and make sure
the receptacle terminals are clean and dry
prior to use. Clean them with a dry cloth if
necessary.
The heater uses 0.4 to 1.0 kilowatt-hours
of energy per hour of use. The system does
not have a thermostat. It will achieve
maximum temperature after
approximately three hours of operation. If
you use the heater longer than three hours,
this will not improve system performance
and will use unnecessary electricity.
