Oil Maintenance Mode
(If Equipped)
The oil maintenance mode is equipped on
Energi models only. The oil maintenance
mode keeps the engine oil quality in good
condition when you drive the vehicle with
limited engine use. If the vehicle is in oil
maintenance mode when you start the
vehicle, a message will appear in the
instrument cluster. While the vehicle is in
oil maintenance mode, the vehicle will run
the engine as necessary.
If you select the EV Now mode while the
vehicle is in the oil maintenance mode, the
oil maintenance mode will be suspended
for as long as you continue driving the
vehicle. The oil maintenance mode will
resume the next time you start the vehicle.
Changing the engine oil and resetting the
oil life monitoring system will suspend the
oil maintenance mode.
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 438).
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.
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 Rotunda tool
300-ROB75240 available from your dealer.
Ford does not recommend the use of
hydrometers or coolant test strips for
measuring coolant concentrations.
