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.
Note: In case of emergency, you can add a
large amount of water without coolant in
order to reach a vehicle service location.
Water alone, without coolant, can cause
engine damage from corrosion, overheating
or freezing. When you reach a service
location, you must have the cooling system
drained and refilled with prediluted coolant
approved to the correct specification. See
Capacities and Specifications (page 379).
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.
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.

MKX (CD9) Canada/United States of America, enUSA, First Printing Maintenance

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
379).
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 WARNINGS
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. Never remove the coolant reservoir
cap when the engine is running or hot.
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:

2. Leave the engine running until the
coolant temperature gauge needle
returns to the normal position. After
several minutes, if the temperature does
not drop, 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 - 2.7L ECOBOOST™/
3.7L WARNING
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. The transmission does not consume fluid.
However, if the transmission slips or shifts
slowly you should check the fluid level. If you
notice a sign of leaking fluid, contact an
authorized dealer.
Checking the Transmission Fluid Level
*
Only check the transmission fluid level when
the engine is at normal operating temprature
179°F (82°C)-199°F (93°C). Normal operating
temprature is reached after driving
approximately
20 mi (30 km). Minimum
A
Maximum
B
Note: Check the fluid level with the engine
running and the transmission in park (P). 1. Make sure that your vehicle is on level
ground.
2. Rotate the automatic transmission fluid cap in a counterclockwise direction. See
Under Hood Overview
(page 308).
3. Remove the cap and dipstick and wipe it with a clean, lint-free cloth. Replace the
cap and dipstick and remove it again to
check the fluid level.
4. Make sure that the fluid level is between
the MIN and the MAX marks. If the fluid
level is at the MIN mark, add fluid
immediately. See
Adding Transmission
Fluid.
5. Replace the automatic transmission fluid
cap and dipstick. Turn it clockwise until
you feel a strong resistance.
Low Fluid Level
If the fluid level is within the minimum range
(below point A) add the correct specification
fluid to be within the hash mark area.
See
Capacities and Specifications (page 379).

MKX (CD9) Canada/United States of America, enUSA, First Printing MaintenanceE190273
AB

Note:
If the fluid level is below the minimum
range do not drive your vehicle. An underfill
conition can damage the transmission.
Correct Fluid Level
If the fluid level is within the hash mark area
(between points A and B) do not add any
fluid.
High Fluid Level
If the fluid level is above the maximum range
(above point B) fluid may need to be
removed. High fluid levels may be caused
by a overheating condition. If you have
operated your vehicle at high speeds, towing
a trailer or in city traffic during hot weather,
allow your vehicle to cool for a minimum of
30 minutes before rechecking the level.
Note: An overfill conition can damage the
transmission.
Adding Transmission Fluid *
1. Rotate the automatic transmission fluid cap in a counterclockwise direction. *2. Remove the cap and dipstick and wipe
it with a clean, lint-free cloth.
3. Add fluid that meets the Ford specifications. See Capacities and
Specifications (page 385). Pour the fluid
directly into the automatic transmission
fluid cap and dipstick hole.
4. Replace the cap and dipstick and remove
it again to check the fluid level.
5. Make sure that the fluid level is between
the MIN and the MAX marks.
6. Replace the automatic transmission fluid
cap and dipstick. Turn it clockwise until
you feel a strong resistance.

counterclockwise direction.
4. Check the fluid level. See Checking the
Transmission Fluid Level.
5. Install in reverse order. Tighten the two air filter assembly securing bolts until you
feel a strong resistance.
BRAKE FLUID CHECK WARNINGS
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. 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. WARNINGS
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. 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.
Only use fluid that meets Ford specifications.
See
Capacities and Specifications (page
379).

MKX (CD9) Canada/United States of America, enUSA, First Printing MaintenanceE170684

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.
322
MKX (CD9) Canada/United States of America, enUSA, First Printing Maintenance

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 System
(page 399). Reset the power windows
bounce-back feature. See Windows and
Mirrors (page 100).
Reset the radio station
presets. See Audio System (page 399). 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.
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.

B 25 feet (7.6 meters).
C
Horizontal reference line.
D
Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a wall
or screen on a level surface,
approximately 25 feet (7.6 meters) away.
2. Measure the height of the headlamp bulb
center from the ground and mark an 8
foot (2.4 meter) horizontal reference line
on the vertical wall or screen at this
height.

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.
CHANGING A BULB WARNINGS
Switch all of the lamps and the ignition
off. Failure to follow this warning could
result in serious personal injury. Bulbs become hot when in use. Let
them cool down before you remove
them. Use the correct specification bulb.
