ENGINE OIL CHECK
To check the engine oil level consistently
and accurately, do the following:
1. Make sure the parking brake is on. Make
sure the transmission is in park (P) or
neutral (N).
2. Run the engine until it reaches normal operating temperature.
3. Make sure that your vehicle is on level ground.
4. Switch the engine off and wait 15 minutes for the oil to drain into the oil
pan. Checking the engine oil level too
soon after you switch the engine off
may result in an inaccurate reading.
5. Open the hood. See Opening and
Closing the Hood (page 244).
6. Remove the dipstick and wipe it with a clean, lint-free cloth. See
Under
Hood Overview (page 247).
7. Replace the dipstick and remove it again to check the oil level. See
Engine Oil Dipstick
(page 248). 8.
Make sure that the oil level is between
the maximum and minimum marks. If
the oil level is at the minimum mark,
add oil immediately. See
Capacities
and Specifications (page 304).
9. If the oil level is correct, replace the dipstick and make sure it is fully seated.
Note: Do not remove the dipstick when the
engine is running.
Note: If the oil level is between the
maximum and minimum marks, the oil level
is acceptable. Do not add oil.
Note: The oil consumption of new engines
reaches its normal level after approximately
3,100 mi (5,000 km)
.
Adding Engine Oil WARNING
Do not remove the filler cap when
the engine is running.
Do not use supplemental engine oil
additives because they are unnecessary
and could lead to engine damage that may
not be covered by the vehicle Warranty.

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 299).
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:
1. Pull off the road as soon as safely
possible and switch the engine off.

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 condition 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 304). 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.
* Vehicles With EcoBoost Engine WARNING
Do not run the engine with the air
filter disconnected. 1. Loosen the clamp holding the air filter
assembly to the rubber hose.
2. Remove the air filter assembly securing
bolts.
3. Lift the air filter assembly to disengage
the locating pins.
4. Rotate the air filter assembly slightly in a counterclockwise direction.
5. Check the transmission fluid level.
6. Install the air filter assembly in reverse
order. Tighten the 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. 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. 255
