ENGINE OIL DIPSTICK
A. MIN
B. MAX
ENGINE OIL CHECK
Note:Check the level before starting the engine.
Note:Make sure that the level is between the MIN and MAX marks.
1. Make sure that your vehicle is on level ground.
2. Turn the engine off and wait 10 minutes for the oil to drain into the
oil pan.
3. Remove the dipstick and wipe it with a clean, lint-free cloth. Replace
the dipstick and remove it again to check the oil level.
If the level is at the MIN mark, add oil immediately.
Adding Engine Oil
Note:Do not remove the filler cap when the engine is running.
Note:Do not add engine oil further than the MAX mark. Oil levels above
the MAX mark may cause engine damage.
Only use oils certified for gasoline engines by the
American Petroleum Institute (API). An oil with this
trademark symbol conforms to the current engine
and emission system protection standards and fuel
economy requirements of the International Lubricants
Specification Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets Ford specifications. SeeCapacities and
Specificationsfor more information.
3. Replace the filler cap. Turn it until you feel a strong resistance.

Resetting the Oil Life Monitoring System
Note:Reset the oil life monitoring only after an oil change.
1. Turn the ignition key to the on position. Do not start the engine.
For vehicles with push-button start, press and hold the start button for
two seconds without pressing the brake pedal. Do not attempt to start
the engine.
2. Press both the accelerator and brake pedals at the same time.
3. Keep both pedals fully pressed.
4. After three seconds, theService: Oil reset in prog.message will be
displayed.
5. After 25 seconds, theService: Oil reset completemessage will be
displayed.
6. Release both the accelerator and brake pedals.
7. TheService: Oil reset completemessage will no longer be
displayed.
8. Rotate the key to the off position.
For vehicles with push-button start, press the start button to turn the
vehicle off completely.
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, EV Now mode will be suspended for as long
as you are in oil maintenance mode.
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.

COOLANT
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 theScheduled Maintenance Information.
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. Refer toAdding Engine Coolantin
this chapter.
The coolant concentration should be maintained at 50%.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool ROB75240 available from your
dealer. Ford does 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/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 theScheduled
Maintenance Information.
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. Refer toAdding Inverter System
Controller Coolantin this chapter.

The coolant concentration should be maintained at 50%.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool ROB75240 available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:It is very important to use prediluted coolant meeting the Ford
specification in order to avoid plugging the small coolant passageways.
Use of concentrated coolant and water may cause coolant passageway
plugging and void the warranty. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:Automotive fluids are not interchangeable; do not use
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Coolant
WARNING:Do not add engine coolant when the engine is hot.
Steam and scalding liquids released from a hot cooling system
can burn you badly. Also, you can be burned if you spill coolant on hot
engine parts.
WARNING:Do not put engine coolant in the windshield washer
fluid container. If sprayed on the windshield, engine coolant
could make it difficult to see through the windshield.
WARNING:To reduce the risk of personal injury, make sure the
engine is cool before unscrewing the coolant pressure relief cap.
The cooling system is under pressure; steam and hot liquid can come
out forcefully when the cap is loosened slightly.
WARNING:Do not add coolant further than the MAX mark.
Note:Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the cooling and/or heating systems. This
damage would not be covered under your vehicle’s warranty.

Note:During normal vehicle operation, the coolant may change color
from orange to pink or light red. As long as the coolant is clear and
uncontaminated, this color change does not indicate the coolant has
degraded nor does it require the coolant to be drained, the system
to be flushed, or the coolant to be replaced.
•DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of coolants may harm your
cooling system. The use of an improper coolant may harm engine,
inverter system controller, and cooling system components and may
void the warranty.
•
In case of emergency, a large amount of water without engine coolant
may be added to the engine cooling system only in order to reach a
vehicle service location. In this instance, the engine cooling system must
be drained, chemically cleaned with Motorcraft® Premium Cooling
System Flush, and refilled with prediluted engine coolant as soon as
possible. Water alone (without engine coolant) can cause engine damage
from corrosion, overheating, or freezing. DO NOT use this method for
the inverter system controller cooling system. The inverter system
controller cooling system operates close to ambient temperature, and is
susceptible to freezing in any subfreezing environment in the absence of
coolant.
•Do not use alcohol, methanol, brine or any engine coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause engine damage from overheating or freezing.
•Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the coolant.
Adding Engine Coolant
1. Remove the Easy Fuel funnel from the storage compartment. Refer to
Running Out of Fuelfor the location of the Easy Fuel funnel.
2. Unscrew the engine coolant reservoir cap slowly. Any pressure will
escape as you unscrew the cap.
3. Position the Easy Fuel funnel in the engine coolant reservoir opening.
Push the Easy Fuel funnel neck fully into the engine coolant reservoir,
past the vent tube, in order to avoid pouring the coolant into the vent
tube and spilling the coolant on the ground.
4. Add prediluted engine coolant to the engine coolant reservoir. Make
sure that the level is between the MIN and MAX marks on the engine
coolant reservoir. Use prediluted engine coolant meeting the Ford
specification. See the technical specifications chart in theCapacities
and Specificationschapter.
