specifications. See Capacities and
Specifications (page 346).
3. Replace the filler cap. Turn it until you feel a strong resistance. 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 468).
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 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 468).
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). 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.
Adding Coolant WARNINGS
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. 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. WARNINGS
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. Do not add coolant further than the
MAX mark.
Note:
Do not use stop leak pellets, cooling
system sealants, or additives as they can
cause damage to the cooling 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.

MKZ Hybrid (), enUSA Maintenance

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
Capacities and Specifications (page 346). •
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
the 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 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 engine coolant.
Adding Engine Coolant
1. Unscrew the engine coolant reservoir cap slowly. Any pressure will escape as
you unscrew the cap.
2. Use a funnel to 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 Capacities and Specifications (page
346
).
3. Close the engine coolant reservoir cap.
291
MKZ Hybrid (), enUSA Maintenance

Whenever you add 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 Capacities
and Specifications (page 346).
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 an
authorized Ford 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.
If you drive in extremely hot climates:
• It may be necessary to have an
authorized Ford dealer decrease the
coolant concentration to 40%.
• A coolant concentration of 40% will
provide improved overheat protection.
Engine coolant concentrations below
40% will decrease the corrosion/freeze
protection characteristics of the engine
coolant and may cause engine damage.
Vehicles driven year-round in non-extreme
climates should use prediluted coolant
meeting the Ford specification for optimum
cooling system and engine protection.

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. Re-start the engine and take your vehicle
to an authorized dealer.
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.
Have an authorized dealer check and change
the transmission fluid at the correct service
interval. See Scheduled Maintenance (page
468). 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.
BRAKE FLUID CHECK
Fluid levels between the MIN and MAX lines
are within the normal operating range; there
is no need to add fluid. If the fluid levels are
outside of the normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric
power steering (EPS) system. There is no
fluid reservoir to check or fill.
WASHER FLUID CHECK WARNING
If you operate your vehicle in
temperatures below 40°F (5°C), use
washer fluid with antifreeze protection.
Failure to use washer fluid with antifreeze
protection in cold weather could result in
impaired windshield vision and increase the
risk of injury or accident. Note:
The front and rear washer systems
are supplied from the same reservoir.
Add fluid to fill the reservoir if the level is low.
Only use a washer fluid that meets Ford
specifications.
See Capacities and
Specifications (page 346).
State or local regulations on volatile organic
compounds may restrict the use of methanol,
a common windshield washer antifreeze
additive. Washer fluids containing
non-methanol antifreeze agents should be
used only if they provide cold weather
protection without damaging the vehicle ’s
paint finish, wiper blades or washer system.
