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.

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.

5. Close the engine coolant reservoir cap.
6. Clean the Easy Fuel funnel.
7. Store the Easy Fuel funnel in the storage compartment.
Whenever you add engine coolant, check the coolant level in the engine
coolant reservoir the next few times you drive the vehicle. If necessary,
add enough prediluted engine coolant to bring the engine coolant level to
the proper level.
Adding Inverter System Controller Coolant
1. Open the inverter system controller coolant reservoir cap.
2. Use a funnel to add prediluted coolant to the inverter system
controller coolant reservoir. Make sure that the level is between the
MIN and MAX marks on the inverter system controller coolant reservoir.
Use prediluted coolant meeting the Ford specification. See the technical
specifications chart in theCapacities and Specificationschapter.
3. Close the inverter system controller coolant reservoir cap.
Whenever you add coolant, check the coolant level in the inverter system
controller coolant reservoir the next few times you drive the vehicle.
If necessary, add enough prediluted coolant to bring the inverter system
controller coolant level to the proper level.
Recycled Engine Coolant
Ford Motor Company does not recommend the use of recycled engine
coolant since a Ford-approved recycling process is not yet available.
Used engine coolant should be disposed of in an appropriate
manner. Follow your community’s regulations and standards for recycling
and disposing of automotive fluids.
Severe Climates
If you drive in extremely cold climates:
•It may be necessary to have a Ford authorized dealer increase the
coolant concentration above 50%.
•A coolant concentration of 60% will provide improved freeze point
protection. Engine coolant concentrations above 60% will decrease
the overheat protection characteristics of the engine coolant and may
cause engine damage.

When Fail-Safe Mode is Activated
WARNING:Fail-safe mode is for use during emergencies only.
Operate the vehicle in fail-safe mode only as long as necessary to
bring the vehicle to rest in a safe location and seek immediate repairs.
When in fail-safe mode, the vehicle will have limited power, will not be
able to maintain high-speed operation, and may completely shut down
without warning, potentially losing engine power, power steering assist,
and power brake assist, which may increase the possibility of a crash
resulting in serious injury.
WARNING:Never remove the coolant reservoir cap while the
engine is running or hot.
You have limited engine power when in the fail-safe mode, so drive the
vehicle with caution. The vehicle will not be able to maintain high-speed
operation and the engine will run rough. Remember that the engine is
capable of completely shutting down automatically to prevent engine
damage, therefore:
1. Pull off the road as soon as safely possible and turn off the engine.
2. Arrange for the vehicle to be taken to an authorized dealer.
3. If this is not possible, wait a short period for the engine to cool.
4. Check the coolant level and replenish if low.
5. Restart the engine and take your vehicle to an authorized dealer.
Note:Driving the vehicle without repairing the engine problem increases
the chance of engine damage. Take your vehicle to an authorized dealer
as soon as possible.
AUTOMATIC TRANSMISSION FLUID CHECK
Note:Transmission fluid should be checked by an authorized dealer.
If required, fluid should be added by an authorized dealer.
The automatic transmission does not have a transmission fluid dipstick.
Refer to yourscheduled maintenance informationfor scheduled
intervals for fluid checks and changes. Your transmission does not
consume fluid. However, the fluid level should be checked if the
transmission is not working properly, (i.e., if the transmission slips
or shifts slowly) or if you notice some sign of fluid leakage.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
