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
Never remove the coolant reservoir
cap when the engine is running or hot.
Note:
Automotive fluids are not
interchangeable. Take care not to put
engine coolant in the windshield washer fluid
reservoir or windshield washer fluid in the
engine coolant reservoir.
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 379). 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 379).
Using water that has not been deionised
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 379).
3. Add enough prediluted coolant to reach
the correct level.
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.

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 379).
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 correct 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. 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. Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after handling. 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.

Exterior Plastic Parts
For routine cleaning we recommend
Motorcraft Detail Wash. If tar or grease spots
are present, we recommend Motorcraft Bug
and Tar Remover.
Stripes or Graphics (If Equipped)
Hand washing your vehicle is preferred
however, pressure washing may be used
under the following conditions:
• Do not use water pressure higher than
2,000 psi (14,000 kPa)
.
• Do not use water hotter than 179°F (82°C).
• Use a spray with a 40° wide spray angle
pattern.
• Keep the nozzle at a
12 in (305 mm)
distance and 90° angle to your vehicle's
surface.
Note: Holding the pressure washer nozzle
at an angle to the vehicle's surface may
damage graphics and cause the edges to
peel away from the vehicle's surface. Underbody
Flush the complete underside of your vehicle
frequently. Keep body and door drain holes
free of debris or foreign material.
Under Hood
For removing black rubber marks from under
the hood we recommend Motorcraft Wheel
and Tire Cleaner or Motorcraft Bug and Tar
Remover.
WAXING
Regular waxing is necessary to protect your
car's paint from the elements. We
recommend that you wash and wax the
painted surface once or twice a year.
When washing and waxing, park your vehicle
in a shaded area out of direct sunlight.
Always wash your vehicle before applying
wax.
•
Use a quality wax that does not contain
abrasives.
• Follow the manufacturer’ s instructions to
apply and remove the wax. •
Apply a small amount of wax in a
back-and-forth motion, not in circles.
• Do not allow wax to come in contact with
any non-body (low-gloss black) colored
trim. The wax will discolor or stain the
parts over time.
•Roof racks.
• Bumpers.
• Grained door handles.
• Side moldings.
• Mirror housings.
• Windshield cowl area.
• Do not apply wax to glass areas.
• After waxing, your car's paint should feel
smooth, and be free of streaks and
smudges.
CLEANING THE ENGINE
Engines are more efficient when they are
clean because grease and dirt buildup keep
the engine warmer than normal.
333
MKX (CD9) Canada/United States of America, enUSA, First Printing Vehicle Care

When washing:
•
Take care when using a power washer
to clean the engine. The high-pressure
fluid could penetrate the sealed parts
and cause damage.
• Do not spray a hot engine with cold water
to avoid cracking the engine block or
other engine components.
• Spray Motorcraft Engine Shampoo and
Degreaser on all parts that require
cleaning and pressure rinse clean. In
Canada, use Motorcraft Engine Shampoo.
• Never wash or rinse the engine while it
is hot or running; water in the running
engine may cause internal damage.
• Never wash or rinse any ignition coil,
spark plug wire or spark plug well, or the
area in and around these locations.
• Cover the battery, power distribution box,
and air filter assembly to prevent water
damage when cleaning the engine. CLEANING THE WINDOWS AND
WIPER BLADES
Car wash chemicals and environmental
fallout can result in windshield and wiper
blade contamination. Dirty windshield and
wipers will result in poor windshield wiper
operation. Keep the windshield and wiper
blades clean to maintain windshield wiper
performance.
To clean the windshield and wiper blades:
•
Clean the windshield with a non-abrasive
glass cleaner. When cleaning the interior
of the windshield, avoid getting any glass
cleaner on the instrument panel or door
panels. Wipe any glass cleaner off these
surfaces immediately.
• For windshields contaminated with tree
sap, chemicals, wax or bugs, clean the
entire windshield using steel wool (no
greater than 0000 grade) in a circular
motion and rinse with water.
• Clean the wiper blades with isopropyl
rubbing alcohol or windshield washer
concentrate. Note:
Do not use razor blades or other
sharp objects to clean or remove decals from
the inside of the heated rear window. The
vehicle warranty does not cover damage
caused to the heated rear window grid lines.
CLEANING THE INTERIOR WARNINGS
Do not use cleaning solvents, bleach
or dye on the vehicle
’s safety belts, as
these actions may weaken the belt webbing. On vehicles equipped with
seat-mounted airbags, do not use
chemical solvents or strong detergents. Such
products could contaminate the side airbag
system and affect performance of the side
airbag in a collision. Note:
Follow the same procedure for
cleaning leather seats when cleaning leather
interior. See Cleaning Leather Seats (page
337).
