Oil Change Indicator Reset; Engine Coolant Check - Ford FUSION HYBRID 2015 Owner's Manual

Selecting EV Now mode when your vehicle
is in the engine management mode will
suspend the engine management mode
for as long as you continue driving your
vehicle. The engine management mode
will resume the next time you start your

ENGINE COOLANT CHECK

Engine Coolant and Inverter
System Controller Coolant
Your vehicle is equipped with two separate
cooling systems. One is for cooling the
engine and one is for cooling the inverter
system controller that is specific to the
hybrid operating system. The two systems
operate similarly, with the inverter system
controller cooling system generally
operating at a lower temperature and
pressure.
Checking the Engine Coolant
When the engine is cold, check the
concentration and level of the engine
coolant at the intervals listed in the
scheduled maintenance information. See
Scheduled Maintenance (page 465).
Note: Make sure that the level is between
the MIN and MAX marks on the engine
coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.

Maintenance
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add prediluted
coolant immediately. See Adding Engine
Coolant in this chapter.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair Coolant and
Battery Refractometer 75240. We do not
recommend the use of hydrometers or
coolant test strips for measuring coolant
concentrations.
Note: Automotive fluids are not
interchangeable. Do not use engine coolant
or antifreeze or windshield washer fluid
outside of its specified function and vehicle
location.
Checking the Inverter System
Controller Coolant
When the engine is cold, check the
concentration and level of the inverter
system controller coolant at the intervals
listed in the scheduled maintenance
information. See Scheduled
Maintenance (page 465).
Note: Make sure that the level is between
the MIN and MAX marks on the inverter
system controller coolant reservoir.
Note: Coolant expands when it is hot. The
level may extend beyond the MAX mark.
Note: If the level is at the MIN mark, below
the MIN mark, or empty, add prediluted
coolant immediately. See Adding Inverter
System Controller Coolant in this chapter.
The coolant concentration should be
maintained within 48% to 50%, which
equates to a freeze point between -30°F
(-34°C) and -34°F (-37°C).
