ENGINE COOLANT CHECK

WARNING: Never remove the coolant

reservoir cap when the engine is running or
hot.

WARNING: Do not put coolant in the

windshield washer reservoir. If sprayed on
the windshield, 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 you loosen the cap slightly.

WARNING: Do not add coolant further

than the MAX mark.

Your vehicle has two separate cooling
systems. One for cooling the engine and a
separate system 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.

302

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

When the engine is cold, check the
concentration and level of the coolant at the
intervals listed in the scheduled maintenance
information. See Scheduled Maintenance
(page 486).

Note: Make sure that the coolant level is
between the MIN and the MAX marks on
the coolant reservoir.

Note:  Coolant expands when it is hot.  The
level may extend beyond the MAX mark.

Maintain coolant concentration within 48%
to 50%, which equates to a freeze point
between -30°F (-34°C) and -34°F (-37°C).
Coolant concentration should be checked
using a refractometer. We do not recommend
the use of hydrometers or coolant test strips
for measuring coolant concentration.

Adding Coolant

WARNING: Do not add engine coolant

when the engine is hot. Failure to follow this
instruction could result in personal injury.

WARNING: Never remove the coolant

reservoir cap when the engine is running or
hot.

Note:  Automotive fluids are not
interchangeable.  Do not use coolant or
windshield washer fluid outside of its
specified function and vehicle location.

Note:  Do not use stop leak pellets, cooling
system sealants, or non-specified additives
as they can cause damage to the engine
cooling or heating systems.  Resulting
component damage may not be covered by
the vehicle Warranty.

It is very important to use prediluted coolant
approved to the correct specification in order
to avoid plugging the small passageways in
the engine cooling system.  See Capacities
and Specifications (page 357).  Do not mix
different colors or types of coolant in your
vehicle. Mixing of engine coolants or using
an incorrect coolant may harm the engine or
cooling system components and may not be
covered by the vehicle Warranty.

Note: If prediluted coolant is not available,
use the approved concentrated coolant
diluting it to 50/50 with distilled water.  See
Capacities and Specifications (page 353).
Using water that has not been deionized
may contribute to deposit formation,
corrosion and plugging of the small cooling
system passageways.

Note:  Coolants marketed for all makes and
models may not be approved to Ford
specifications and may cause damage to
the cooling system.  Resulting component
damage may not be covered by the vehicle
Warranty.

If the coolant level is at or below the
minimum mark, add prediluted coolant
immediately.

To top up the coolant level do the following:

1. Unscrew the cap slowly. Any pressure

escapes as you unscrew the cap.

2. Add prediluted coolant approved to the

correct specification.  See Capacities and
Specifications (page 353).

3. Add enough prediluted coolant to reach

the correct level.

303

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

4. Replace the coolant reservoir cap, turn

it clockwise until you feel a strong
resistance.

5. Check the coolant level in the coolant

reservoir the next few times you drive
your vehicle. If necessary, add enough
prediluted engine coolant to bring the
coolant level to the correct level.

If you have to add more than 1.1 qt (1 L) of
engine coolant per month, have your vehicle
checked as soon as possible. Operating an
engine with a low level of coolant can result
in engine overheating and possible engine
damage.

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.

In case of emergency, you can add a large
amount of water without engine coolant in
order to reach a vehicle service location. In
this instance, qualified personnel:

1. Must drain the cooling system.

2. Chemically clean the cooling system.
3. Refill with prediluted coolant as soon as

possible.

Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing.

Do not use the following as a coolant
substitute:
•

Alcohol.

•

Methanol.

•

Brine.

•

Any coolant mixed with alcohol or
methanol antifreeze.

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.

Recycled Coolant

We do not recommend the use of recycled
coolant as an approved recycling process is
not yet available.

Dispose of used engine coolant 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 increase the
coolant concentration above 50%.

•

A coolant concentration of 60% provides
improved freeze point protection. 
Coolant concentrations above 60%
decrease the overheat protection
characteristics of the coolant and may
cause engine damage.

304

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

If you drive in extremely hot climates:
•

You can decrease the coolant
concentration to 40%.

•

Coolant concentrations below 40%
decrease the freeze and corrosion
protection characteristics of the coolant
and may cause engine damage.

Vehicles driven year-round in non-extreme
climates should use prediluted coolant for
optimum cooling system and engine
protection.

Coolant Change

At specific mileage intervals, as listed in the
scheduled maintenance information, the
coolant should be changed. Add prediluted
coolant approved to the correct specification.
See Capacities and Specifications (page
353).

Fail-Safe Cooling

Fail-safe cooling allows you to temporarily
drive your vehicle before any incremental
component damage occurs. The fail-safe
distance depends on ambient temperature,
vehicle load and terrain.

How Fail-Safe Cooling Works

If the engine begins to overheat, the coolant
temperature gauge moves toward the red
zone:

A warning lamp illuminates and a
message may appear in the
information display.

If the engine reaches a preset
over-temperature condition, the engine
automatically switches to alternating cylinder
operation.  Each disabled cylinder acts as an
air pump and cools the engine.

When this occurs, your vehicle still operates,
however:
•

Engine power is limited.

•

The air conditioning system turns off.

Continued operation increases the engine
temperature, causing the engine to
completely shut down.  Your steering and
braking effort increases in this situation.

When the engine temperature cools, you can
re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

When Fail-Safe Mode Is Activated

WARNING: Fail-safe mode is for use

during emergencies only. Operate your
vehicle in fail-safe mode only as long as
necessary to bring your vehicle to rest in a
safe location and seek immediate repairs.
When in fail-safe mode, your 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 when the engine is running or
hot.

305

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

Your vehicle has limited engine power when
in the fail-safe mode, drive your vehicle with
caution. Your vehicle does not maintain
high-speed operation and the engine may
operate poorly.

Remember that the engine is capable of
automatically shutting down to prevent
engine damage.  In this situation:

1. Pull off the road as soon as safely

possible and switch the engine off.

2. If you are a member of a roadside

assistance program, we recommend that
you contact your roadside assistance
service provider.

3. If this is not possible, wait a short period

for the engine to cool.

4. Check the coolant level. If the coolant

level is at or below the minimum mark,
add prediluted coolant immediately.

5. When the engine temperature cools, you

can re-start the engine. Have your vehicle
checked as soon as possible to minimize
engine damage.

Note: Driving your vehicle without repair
increases the chance of engine damage.

Engine Coolant Temperature
Management

 (If Equipped)

WARNING: To reduce the risk of crash

and injury, be prepared that the vehicle
speed may reduce and the vehicle may not
be able to accelerate with full power until the
coolant temperature reduces.

If you tow a trailer with your vehicle, the
engine may temporarily reach a higher
temperature during severe operating
conditions, for example ascending a long or
steep grade in high ambient temperatures.

At this time, you may notice the coolant
temperature gauge moves toward the red
zone and a message may appear in the
information display.

You may notice a reduction in vehicle speed
caused by reduced engine power in order
to manage the engine coolant temperature. 
Your vehicle may enter this mode if certain
high-temperature and high-load conditions
take place.  The amount of speed reduction
depends on vehicle loading, grade and
ambient temperature. If this occurs, there is
no need to pull off the road.  You can
continue to drive your vehicle.

The air conditioning may automatically turn
on and off during severe operating
conditions to protect the engine from
overheating. When the coolant temperature
decreases to the normal operating
temperature, the air conditioning turns on.

If the coolant temperature gauge moves fully
into the red zone, or if the coolant
temperature warning or service engine soon
messages appear in your information display,
do the following:

1. Pull off the road as soon as safely

possible and shift the transmission into
park (P).

306

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

2. Leave the engine running until the

coolant temperature gauge needle
returns to the normal position.  If the
temperature does not drop after several
minutes, follow the remaining steps.

3. Switch the engine off and wait for it to

cool. Check the coolant level.

4. If the coolant level is at or below the

minimum mark, add prediluted coolant
immediately.

5. If the coolant level is normal, restart the

engine and continue.

AUTOMATIC TRANSMISSION
FLUID CHECK

Note: Transmission fluid should be checked
by an authorized dealer. If required, fluid
should be added by an authorized dealer.

Have an authorized dealer check and change
the transmission fluid at the correct service
interval.  See Maintenance (page 298). 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

WARNING: Do not use any fluid other

than the recommended brake fluid as this
will reduce brake efficiency. Use of incorrect
fluid could result in the loss of vehicle
control, serious personal injury or death.

WARNING: Only use brake fluid from

a sealed container. Contamination with dirt,
water, petroleum products or other materials
may result in brake system damage or failure.
Failure to adhere to this warning could result
in the loss of vehicle control, serious
personal injury or death.

WARNING: Do not allow the fluid to

touch your skin or eyes. If this happens, rinse
the affected areas immediately with plenty
of water and contact your physician.

WARNING: A fluid level between the

MAX and MIN lines is within the normal
operating range and there is no need to add
fluid. A fluid level not in the normal operating
range could compromise the performance
of the system. Have your vehicle checked
immediately.

To avoid fluid contamination, the reservoir
cap must remain in place and fully tight,
unless you are adding fluid.

307

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

Only use fluid that meets Ford specifications.
See Capacities and Specifications (page
353).

WASHER FLUID CHECK

WARNING: If you operate your vehicle

in temperatures below 41.0°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 our
specifications.  See Capacities and
Specifications (page 353).

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.

FUEL FILTER

Your vehicle is equipped with a lifetime fuel
filter that is integrated with the fuel tank.
Regular maintenance or replacement is not
needed.

CHANGING THE 12V BATTERY

WARNING: Batteries normally produce

explosive gases which can cause personal
injury. Therefore, do not allow flames, sparks
or lighted substances to come near the
battery. When working near the battery,
always shield your face and protect your
eyes. Always provide correct ventilation.

WARNING: When lifting a plastic-cased

battery, excessive pressure on the end walls
could cause acid to flow through the vent
caps, resulting in personal injury and damage
to the vehicle or battery. Lift the battery with
a battery carrier or with your hands on
opposite corners.

WARNING: Keep batteries out of reach

of children. Batteries contain sulfuric acid.
Avoid contact with skin, eyes or clothing.
Shield your eyes when working near the
battery to protect against possible splashing
of acid solution. In case of acid contact with
skin or eyes, flush immediately with water
for a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed, call a
physician immediately.

WARNING: Battery posts, terminals

and related accessories contain lead and
lead compounds. Wash hands after handling.

308

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

WARNING: For vehicles with

Auto-Start-Stop the battery requirement is
different. You must replace the battery with
one of exactly the same specification.

Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.

When a battery replacement is required, you
must use a recommended replacement
battery that matches the electrical
requirements of the vehicle.

Note: If your vehicle has a battery cover,
after cleaning or replacing the battery, make
sure you reinstall it.

Note: See an authorized dealer for battery
access, testing, or replacement.

To make sure the battery management
system works correctly, do not connect an
electrical device ground connection directly
to the battery negative post. This can cause
inaccurate measurements of the battery
condition and potential incorrect system
operation.

Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect battery performance and durability.
This may also affect the performance of
other electrical systems in the vehicle.

If you see any corrosion on the battery or
terminals, remove the cables from the
terminals and clean with a wire brush.  You
can neutralize the acid with a solution of
baking soda and water.

Because your vehicle’s engine is
electronically-controlled by a computer,
some engine control settings are maintained
by power from the battery. Some engine
computer settings, like the idle trim and fuel
trim strategy, optimize the driveability and
performance of the engine. The clock and
radio station presets are also maintained in
memory by power from the low-voltage
battery. These settings are erased when a
technician disconnects and connects the
low-voltage battery.

To restore the settings, do the following:

Note: Until you switch the ignition to the on
position, you will receive a message in your
information display stating that your vehicle
is not in park.

1. Apply the parking brake.

2. Shift into park (P) or neutral (N).
3. Switch off all accessories.

4. Press the brake pedal and start your

vehicle.

5. Run the engine until it reaches normal

operating temperature. While the engine
is warming up, complete the following:
Reset the clock.  See Audio Unit (page
368).  Reset the power windows
bounce-back feature.  See Power
Windows (page 94).  Reset the radio
station presets.  See Audio Unit (page
368).

6. Allow the engine to idle for at least one

minute.

7. Drive the vehicle at least 10 mi (16 km) to

completely relearn the idle trim and fuel
trim strategy.

309

MKZ Hybrid (CC9) Hybrid Electric Vehicle (HEV), Canada/United States of America, enUSA, Edition date: 201805, First-Printing

Maintenance

Note: If you do not allow the engine to
relearn the idle and fuel trim strategy, the
idle quality of your vehicle may be adversely
affected until the engine computer
eventually relearns the idle trim and fuel trim
strategy.

Note: Certain features may not operate if
the battery monitor system is not reset with
a scan tool following a jump start or battery
replacement. Normal electrical accessory
operation should resume after your vehicle
is left undisturbed for 8 hours.

Make sure that you dispose of old batteries
in an environmentally friendly way.  Seek
advice from your local authority about
recycling old batteries.

If storing your vehicle for more than 30 days
without recharging the battery, we
recommend that you disconnect the battery
cables to maintain battery charge for quick
starting.

CHECKING THE WIPER BLADES

E142463

Run the tip of your fingers over the edge of
the blade to check for roughness.

Clean the wiper blades with washer fluid or
water applied with a soft sponge or cloth.

CHANGING THE WIPER BLADES
