3. Add fluid that meets the Ford
specifications. See Capacities and
Specifications (page 308). 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 Turbocharged Engines WARNING
Do not start the engine with the air
filter removed. This can cause
damage not covered by the vehicle
Warranty and can result in serious injury. 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. 256

WARNINGS
Battery posts, terminals and related
accessories contain lead and lead
compounds. Wash hands after
handling. Your vehicle has a Motorcraft®
maintenance-free battery which normally
does not require additional water during
its life of service.
Note:
If your vehicle's battery has a cover
or 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.
2. Shift into park (P).
3. Switch off all accessories.
4. Fully press the brake pedal and start the 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 317). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 87).
Reset the radio station presets. See
Audio System
(page 317).
6. Allow the engine to idle for at least one
minute. If the engine turns off, press
the accelerator pedal to start the
engine.
258
Flex (TP3) , enUSA, Edition date: 201801, Second Printing Maintenance

7. While the engine is running, press the
brake pedal and shift into neutral (N).
8. Allow the engine to run for at least one
minute by pressing on the accelerator
pedal.
9. Drive the vehicle at least 12 mi (20 km)
to completely relearn the idle 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.
Make sure that you dispose of old batteries
in an environmentally friendly way. Seek
advice from your local authority about
recycling old batteries.
CHECKING THE WIPER
BLADES Run the tip of your fingers over the edge of
the blade to check for roughness.
Clean the wiper blades with washer fluid
or water applied with a soft sponge or
cloth.
CHANGING THE WIPER
BLADES
You can improve poor wiper quality by
cleaning the wiper blades and the
windshield. Replace the wiper blades at least annually
for optimum performance.
Front Wiper Blades
1.
Lift the wiper arm away from the glass.
Note: Do not hold the wiper blade when
lifting the wiper arm.
Note: Make sure that the wiper arm does
not spring back against the glass when the
wiper blade is not attached. 2. Release the wiper blade lock (A) and
separate the wiper blade from the
wiper arm.
3. Remove the wiper blade.
4. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back on the windshield. The wiper arms will
automatically return to their normal position
when you turn the ignition on.

CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running. When changing the engine air filter, do not
allow debris or foreign material to enter
the air induction system. Engine
components are susceptible to damage
not covered by the vehicle Warranty.
Change the air filter element at the correct
interval. See Scheduled Maintenance
(page 447).
Incorrect component use can cause
damage not covered by the vehicle
Warranty. See
Motorcraft Parts (page
303).
To replace the air filter element do the
following: 1. Remove the clips that secure the air
filter housing cover.
2. Carefully lift the air filter housing cover.
3. Remove the air filter element from the
air filter housing.
4. Wipe any dirt or debris from the air filter
housing and cover to make sure no dirt
gets in the engine and that you have a
good seal.
5. Install a new air filter element. Be careful not to crimp the filter element
edges between the air filter housing
and cover. This could cause filter
damage and allow unfiltered air to
enter the engine if it is not properly
seated.
6. Install the air filter housing cover.
7. Engage the clips to secure the air filter housing cover to the air filter housing.

CLEANING THE EXTERIOR
Wash your vehicle regularly with cool or
lukewarm water and a neutral pH
shampoo, we recommend Motorcraft
Detail Wash. •
Never use strong household detergents
or soap, for example dish washing or
laundry liquid. These products can
discolor and spot painted surfaces.
• Never wash your vehicle when it is hot
to the touch, or during strong or direct
sunlight.
268
Flex (TP3) , enUSA, Edition date: 201801, Second Printing Vehicle Care

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. 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.

Flex (TP3) , enUSA, Edition date: 201801, Second Printing Vehicle Care

REPAIRING MINOR PAINT
DAMAGE
Authorized dealers have touch-up paint to
match your vehicle
’s color. Your vehicle
color code is printed on a sticker on the
front, left-hand side door jamb. Take your
color code to your authorized dealer to
make sure you get the correct color.
Before repairing minor paint damage, use
a cleaner such as Motorcraft Bug and Tar
Remover to remove particles such as bird
droppings, tree sap, insect deposits, tar
spots, road salt and industrial fallout.
Always read the instructions before using
cleaning products.
CLEANING THE WHEELS (If
Equipped)
1. Regularly clean them with a wheel cleaner. We recommend that you use
Ford approved wheel cleaner if
available.
2. Remove dirt and brake dust with a sponge.
3. Remove tar and grease with a bug and
tar remover. We recommend that you
use Ford approved bug and tar remover
if available.
4. Thoroughly rinse the wheels with water
after cleaning.
If you intend on 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
reduces the risk of corrosion of the brake
discs, brake pads and linings.
Do not clean the wheels when they are hot.
Note: Some car washes could damage
wheel rims and covers. Note:
Using non-recommended cleaners,
harsh cleaning products, chrome wheel
cleaners or abrasive materials could
damage wheel rims and covers.
VEHICLE STORAGE
If you plan on storing your vehicle for 30
days or more, read the following
maintenance recommendations to make
sure your vehicle stays in good operating
condition.
We engineer and test all motor vehicles
and their components for reliable, regular

long-term storage may lead to degraded
engine performance or failure unless you
use specific precautions to preserve engine
components.
General
• Store all vehicles in a dry, ventilated
place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they
require regular maintenance to protect
against rust and damage.
Body
• Wash your vehicle thoroughly to
remove dirt, grease, oil, tar or mud from
exterior surfaces, rear-wheel housing
and the underside of front fenders.
• Periodically wash your vehicle if it is
stored in exposed locations.
• Touch-up exposed or primed metal to
prevent rust.
• Cover chrome and stainless steel parts
with a thick coat of auto wax to prevent
discoloration. Re-wax as necessary
when you wash your vehicle.
• Lubricate all hood, door and luggage
compartment hinges and latches with
a light grade oil.
273

• When removing your vehicle from
storage, check coolant fluid level.
Confirm that there are no cooling
system leaks and that fluid is at the
recommended level.
Battery
• Check and recharge as necessary. Keep
connections clean.
• 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. Note:
It is necessary to reset memory
features if battery cables are disconnected.
Brakes
• Make sure the brakes and parking brake
release fully.
Tires
• Maintain recommended air pressure.
Miscellaneous
• Make sure all linkages, cables, levers
and pins under your vehicle are covered
with grease to prevent rust.
• Move vehicles at least 25 ft (7.5 m)
every 15 days to lubricate working parts
and prevent corrosion.
Removing Vehicle From Storage
When your vehicle is ready to come out of
storage, do the following:
• Wash your vehicle to remove any dirt
or grease film build-up on window
surfaces.
• Check windshield wipers for any
deterioration.
• Check under the hood for any foreign
material that may have collected
during storage such as mice or squirrel
nests.
• Check the exhaust for any foreign
material that may have collected
during storage.
• Check tire pressures and set tire
inflation per the Tire Label.
• Check brake pedal operation. Drive
your vehicle
15 ft (4.5 m) back and
forth to remove rust build-up.
