•
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
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 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 302).
3. Close the engine coolant reservoir cap.
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 302).
3. Close the inverter system controller coolant reservoir cap.
257
MKZ (CC9) Maintenance

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.
What You Should Know About Fail-
Safe Cooling
If the engine coolant supply is depleted,
this feature allows the vehicle to be driven
temporarily before incremental component
damage is incurred. The “fail-safe ”
distance depends on ambient
temperatures, vehicle load and terrain.
How Fail-Safe Cooling Works
If the engine begins to overheat, the
engine coolant temperature gauge will
move to the red (hot) area and: The coolant temperature
warning light will illuminate.
The service engine soon
indicator will illuminate.
If the engine reaches a preset
over-temperature condition, the engine
will automatically switch to alternating
cylinder operation. Each disabled cylinder
acts as an air pump and cools the engine.
258
MKZ (CC9) Maintenance

When this occurs the vehicle will still
operate. However:
•
The engine power will be limited.
• The air conditioning system will be
disabled.
Continued operation will increase the
engine temperature and the engine will
completely shut down, causing steering
and braking effort to increase.
Once the engine temperature cools, the
engine can be re-started. Take your
vehicle to an authorized dealer as soon
as possible to minimize engine damage.
When Fail-Safe Mode Is Activated WARNINGS
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. Never remove the coolant reservoir
cap while the engine is running or
hot. 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. 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. 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 412). 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.
259
MKZ (CC9) Maintenance

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 302).
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 WARNINGS
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 proper
ventilation. 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.
260
MKZ (CC9) Maintenance

WARNINGS
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. Your vehicle is equipped with a
Motorcraft® maintenance-free battery
which normally does not require additional
water during its life of service.
Note:
If your battery has a cover/shield,
make sure it is reinstalled after the battery
has been cleaned or replaced.
Note: See an authorized dealer for low
voltage battery access, testing, or
replacement.
When a low voltage battery replacement
is necessary, see an authorized dealer to
replace the low voltage battery with a Ford
recommended replacement low voltage
battery that matches the electrical
requirements of the vehicle
To ensure proper operation of the battery
management system (BMS), do not allow
a technician to connect any electrical
device ground connection directly to the
low voltage battery negative post. A
connection at the low voltage battery
negative post can cause inaccurate
measurements of the battery condition
and potential incorrect system operation. Note:
If a person adds electrical or
electronic accessories or components to
the vehicle, the accessories or
components may adversely affect the low
voltage battery performance and
durability and may also affect the
performance of other electrical systems
in the vehicle.
For longer, trouble-free operation, keep
the top of the battery clean and dry. Also,
make certain the battery cables are always
tightly fastened to the battery terminals.
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.
When a battery replacement is required,
the battery should only be replaced with
a Ford recommended replacement battery
that matches the electrical requirements
of the vehicle.
Because your vehicle ’s engine is
electronically-controlled by a computer,
some engine control settings are
maintained by power from the low voltage
battery. Some engine computer settings,
like the idle trim and fuel trim strategy,
optimize the driveability and performance
of the engine. Some other computer
settings, like the clock and radio station
presets, are also maintained in memory
by power from the low voltage battery.
When a technician disconnects and
connects the low voltage battery, these
settings are erased. Complete the
following procedure in order to restore the
settings:
1. With the vehicle at a complete stop, set the parking brake.

4.
On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted. 5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the
horizontal reference line.
6. Close the hood and turn off the lamps. Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
CHANGING A BULB
Lamp Assembly Condensation
Exterior lamps are vented to accommodate
normal changes in pressure. Condensation
can be a natural by-product of this design.
When moist air enters the lamp assembly
through the vents, there is a possibility that
condensation can occur when the
temperature is cold. When normal
condensation occurs, a thin film of mist
can form on the interior of the lens. The
thin mist eventually clears and exits
through the vents during normal operation.
Clearing time may take as long as 48
hours under dry weather conditions.
Examples of acceptable condensation are:
•
Presence of thin mist (no streaks, drip
marks or droplets).
• Fine mist covers less than 50% of the
lens.
Examples of unacceptable moisture
(usually caused by a lamp water leak) are:
• Water puddle inside the lamp.
• Large water droplets, drip marks or
streaks present on the interior of the
lens.
Take your vehicle to a dealer for service
if any of the above conditions of
unacceptable moisture are present.
