Check the level before starting the engine
and make sure that the level is between
the MIN and the MAX marks.
1. Make sure that your vehicle is on level ground.
2. Switch the engine off and wait 10 minutes for the oil to drain into the oil
pan.
3. Remove the dipstick and wipe it with a clean, lint-free cloth. Replace the
dipstick and remove it again to check
the oil level.
If the oil level is at the minimum mark, add
oil immediately. Adding Engine Oil
Note:
Do not remove the filler cap when
the engine is running.
Note: Do not add oil further than the MAX
mark. Oil levels above the MAX mark may
cause engine damage. Only use oils certified for gasoline engines
by the American Petroleum Institute (API).
An oil with this trademark symbol
conforms to the current engine and
emission system protection standards and
fuel economy requirements of the
International Lubricants Specification
Advisory Council (ILSAC), comprised of
U.S. and Japanese automobile
manufacturers.
1. Remove the filler cap.
2. Add engine oil that meets the Ford
specifications. See

Low Engine Use (If Equipped)
The low engine use mode is equipped on
Energi models only. The low engine use
mode keeps the engine oil quality in good
condition when you drive your vehicle with
limited engine use. If your vehicle is in low
engine use mode when you start the
vehicle, a message appears in the
information display. When your vehicle is
in low engine use mode, your vehicle runs
the engine as necessary.
Selecting EV Now mode when your vehicle
is in the low engine use mode suspends
the low engine use mode for as long as you
continue driving your vehicle. The low
engine use mode resumes the next time
you start your vehicle.
Changing the engine oil and resetting the
oil life monitoring system suspends the low
engine use mode.
Operating in Cold Climates and
Short Driving Cycles
Some gasoline engines may experience a
buildup of moisture in the engine oil if
repeatedly operated in cold weather and
short driving cycles that do not fully warm
the engine.
When you see a thick milky substance
under the oil cap, this indicates moisture
is present.
This condition can be more prevalent in
gas electric hybrid vehicles that run the gas
engine for very short driving cycles.
To prevent engine damage under these
conditions customers should follow these
steps:
• Drive your vehicle at full engine
temperature for 15 to 30 minutes.
• Drive your vehicle at highway speeds.
• Drive your vehicle with the defroster
(hybrid vehicles) at full. We recommend frequent oil changes.
Follow severe duty cycle in the
maintenance guide. This helps remove the
moisture contaminated oil from the engine.
Cold Weather Operation
To determine if the shortened oil change
interval or warming of the engine is
sufficient, clean and check the oil fill cap
on a regular basis. This will confirm that
the thick milky substance is not returning.
When extreme cold weather and sub-zero
conditions exist, fuel may be found in the
engine oil. This is caused by the engine not
reaching its full engine temperature.
In this situation, carry out the above steps
to prevent engine damage.

•
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.
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.

4. If necessary, apply more soap and
water solution or cleaning product to
a clean, soft cloth and press it onto the
soiled area. Allow this to set at room
temperature for 30 minutes.
5. Remove the soaked cloth, then with a clean, damp cloth, use a rubbing
motion for 60 seconds on the soiled
area.
6. Dry the area with a clean, soft cloth.
CLEANING LEATHER SEATS (If
Equipped)
Note: Follow the same procedure as
cleaning leather seats for cleaning leather
instrument panels and leather interior trim
surfaces.
For routine cleaning, wipe the surface with
a soft, damp cloth and a mild soap and
water solution. Dry the area with a clean,
soft cloth.
For cleaning and removing stains such as
dye transfer, use Motorcraft Premium
Leather and Vinyl Cleaner or a
commercially available leather cleaning
product for automotive interiors.
Note: Test any cleaner or stain remover on
an inconspicuous area.
You should:
• Remove dust and loose dirt with a
vacuum cleaner.
• Clean and treat spills and stains as
soon as possible.
Do not use the following products as these
may damage the leather:
• Oil and petroleum or silicone-based
leather conditioners.
• Household cleaners. •
Alcohol solutions.
• Solvents or cleaners intended
specifically for rubber, vinyl and
plastics.
REPAIRING MINOR PAINT
DAMAGE
You should repair paintwork damage
caused by stones from the road or minor
scratches as soon as possible. A choice of
products are available from an authorized
dealer.
Remove particles such as bird droppings,
tree sap, insect deposits, tar spots, road
salt and industrial fallout before repairing
paint chips.
Always read and follow the manufacturer ’s
instructions before using the products.
CLEANING THE WHEELS
Note: Do not apply a cleaning chemical to
warm or hot 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 of time.
Note: Do not use hydrofluoric acid-based
or high caustic-based wheel cleaners, steel
wool, fuels or strong household detergent.
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, brake pads and
linings.
Note: Some automatic car washes may
cause damage to the finish on your wheel
rims and covers.
