ENGINE OIL CHECK
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
Capacities and
Specifications (page 282).
3. Wipe off any spilled oil.
4. Replace the filler cap. Turn it until you feel a strong resistance.

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.

(If Equipped)
Resetting the Oil Life Monitoring
System
Only reset the oil life monitoring system
after changing the engine oil and oil filter.
1. Switch the ignition on. Do not start the
engine. For vehicles with push-button
start, press and hold the start button
for two seconds without pressing the
brake pedal. Do not start the engine.
2. Press the accelerator and brake pedals
at the same time.
3. Keep the accelerator and brake pedals
fully pressed.
4. After three seconds, a message confirming that the reset is in progress
will be displayed.
5. After 25 seconds, a message confirming that the reset is complete
will be displayed.
6. Release the accelerator and brake pedals.

•
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.

Alloy wheels and wheel covers are coated
with a clear coat paint finish. To maintain
their condition we recommend that you:
•
Clean them weekly with the
recommended wheel and tire cleaner.
• Use a sponge to remove heavy
deposits of dirt and brake dust
accumulation.
• Rinse them thoroughly with a
pressurized stream of water when you
have completed the cleaning process.
We recommend that you use Ford service
wheel cleaner. Make sure that you read
and follow the manufacturer ’s instructions.
Using other non-recommended cleaning
products can result in severe and
permanent cosmetic damage.
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
driving. Under various conditions,
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 you store vehicles 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 you
store it 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.
• Cover interior trim to prevent fading.
• Keep all rubber parts free from oil and
solvents.
Engine
• Change the engine oil and filter prior to
storage because used engine oil
contains contaminates which may
cause engine damage.
• Start the engine every 15 days for a
minimum of 15 minutes. Run at fast idle
with the climate controls set to defrost
until the engine reaches normal
operating temperature.
• With your foot on the brake, shift
through all the gears while the engine
is running.
• We recommend that you change the
engine oil before you use your vehicle
again.
Fuel System
• Fill the fuel tank with high-quality fuel
until the first automatic shutoff of the
fuel pump nozzle.
