ENGINE COOLANT CHECK -
2.0L ECOBOOST™/3.7L
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
440
).
Note: Make sure that the level is
between the MIN and MAX marks on
the 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
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 degrees (-34 C) and
-34 F (-37 C).
268
Maintenance

Note:
For best results, coolant
concentration should be tested with a
refractometer such as Rotunda tool
300-ROB75240 available from your
authorized dealer. Ford does 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 Engine 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. 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
engine cooling or heating systems. This
damage would not be covered under
your vehicle ’s warranty.
Note: During normal vehicle operation,
the engine coolant may change color
from orange to pink or light red. As long
as the engine coolant is clear and
uncontaminated, this color change
does not indicate the engine coolant
has degraded nor does it require the
engine coolant to be drained, the
system to be flushed, or the engine
coolant to be replaced.
• Do not mix different colors or types
of coolant in your vehicle. Make
sure the correct coolant is used.
Mixing of engine coolants may
harm your engine ’s cooling system.
The use of an improper coolant
may harm engine and cooling
system components and may void
the warranty. Use prediluted
engine coolant meeting the Ford
specification. See Capacities and
Specifications (page 325).
• In case of emergency, a large
amount of water without engine
coolant may be added in order to
reach a vehicle service location. In
this instance, the 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.

Maintenance

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.
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. 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.
271
Maintenance

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.
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.
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 and
filter at the correct service interval.
See Scheduled Maintenance (page
440). Your transmission does not
consume fluid. However, the fluid level
should be checked if the transmission
is not working properly, 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. 6F35/HF35 transmission
(If
Equipped)
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.
Refer to your scheduled maintenance
information for scheduled intervals
for fluid checks and changes. Your
transmission does not consume fluid.
However, the fluid level should be
checked if the transmission is not
working properly, (For example: if the
transmission slips or shifts slowly) or
if you notice some sign of fluid
leakage. See
Scheduled
Maintenance (page 440).
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.
6F50/6F55 Transmission
(If
Equipped) WARNINGS
The dipstick cap and surrounding
components may be hot; gloves
are recommended. Use gloves when moving the air
filter assembly. Components will
be hot. 272
Maintenance

Before adding any fluid, make sure the
correct type is used. The type of fluid
used is normally indicated on the
dipstick and also in the Technical
Specifications section in this chapter.
Note:
An overfill condition of
transmission fluid may cause shift or
engagement concerns or possible
damage.
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. Reinstall
the air filter assembly. After the fluid
level has been checked and adjusted
as necessary, do the following:
1. Shut the engine off.
2. Loosen the clamp holding the air filter assembly to the rubber hose.
3. Rotate the air filter assembly 90 degrees clockwise without
disconnecting the sensor.
4. Seat the air filter assembly back into the grommets by pushing
down on the air filter assembly.
5. Tighten the clamp.
6. Install and tighten two bolts that
attach air filter assembly to the
front of the vehicle. 7.
Install the bolt cover (if equipped).
8. Reinstall the harness retaining clip
into the front of the air filter
assembly.
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.
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.

MaintenanceE158846

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.
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.
It is recommended that the negative
battery cable terminal be
disconnected from the battery if you
plan to store your vehicle for an
extended period of time.
To ensure proper operation of the
battery management system (BMS),
any electrical devices that are added
to the vehicle should not have their
ground connection made directly at
the negative battery post. A
connection at the negative battery
post can cause inaccurate
measurements of the battery
condition and potential incorrect
system operation. Note:
Electrical or electronic
accessories or components added to
the vehicle by the dealer or the owner
may adversely affect battery
performance and durability and may
also affect the performance of other
electrical systems in the vehicle.
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.
When the battery is disconnected or
a new battery installed, the automatic
transmission must relearn its adaptive
strategy. As a result of this, the
transmission may shift firmly when
first driven. This operation is
considered normal and will fully
update transmission operation to its
optimum shift feel.
If the battery has been disconnected
or a new battery has been installed,
the clock and the preset radio stations
must be reset once the battery is
reconnected.
Note: Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized standards
for disposal. Call your local authorized
recycling center to find out more about
recycling automotive batteries.

Maintenance

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.
REMOVING A HEADLAMP
See an authorized dealer. 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.
Replacing Bulbs
For replacing bulbs, see your
authorized dealer.

CLEANING THE ALLOY
WHEELS
Note: Do not apply a cleaning
chemical to warm or hot wheel rims
and covers.
Note: Some automatic car washes
may cause damage to the finish on
your wheel rims and covers.
Note: Industrial-strength (heavy-duty)
cleaners or cleaning chemicals, in
combination with brush agitation to
remove brake dust and dirt, could wear
away the clear coat finish over a period
time. Note:
Do not use hydrofluoric
acid-based or high caustic-based
wheel cleaners, steel wool, fuels or
strong household detergents.
Note: If you intend parking your vehicle
for an extended period after cleaning
the wheels with a wheel cleaner, drive
your vehicle for a few minutes before
doing so. This will reduce the risk of
increased corrosion of the brake discs.
Alloy wheels and wheel covers are
coated with a clear coat paint finish.
To maintain their condition we
recommend that you:
• Clean the wheels weekly, with the
recommended Ford service wheel
and tire cleaner. Apply using
manufacturer's instructions. Use
Motorcraft® Wheel and Tire
Cleaner. See cleaning products
(page ?).
• Use a sponge to remove heavy
deposits of dirt and brake dust
accumulation.
• Rinse thoroughly with a strong
stream of water when you have
completed the cleaning process.
• To remove tar and grease, use
Motorcraft® Bug and Tar Remover.
