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 275).
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.
ENGINE COOLANT CHECK 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. Engine Coolant and Inverter
System Controller Coolant
Your vehicle has two separate cooling
systems. One is for cooling the engine and
one is for cooling the inverter system
controller that is specific to the hybrid
operating system. The two systems
operate similarly, with the inverter system
controller cooling system generally
operating at a lower temperature and
pressure.
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 420).
Note: Make sure that the level is between
the MIN and MAX marks on the engine
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 prediluted
coolant immediately. See
Adding Engine
Coolant in this chapter.
Maintain coolant concentration within
48% to 50%, which equates to a freeze
point between -30°F (-34°C) and -34°F
(-37°C).
Note: For best results, coolant
concentration should be tested with a
refractometer such as Robinair® Coolant
and Battery Refractometer 75240. We do
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.

REMOVING A HEADLAMP
1. Make sure the headlamp control is in
the off position and open the hood.
2. Remove the two screws from the headlamp assembly.
3. Carefully pull the headlamp assembly as far as possible towards the front of
the vehicle to disengage it from the
lower fixing point.
4. Carefully lift the outer side of the headlamp and remove it.
5. Disconnect the electrical connector.
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 Headlamp Bulbs WARNING
Handle a halogen headlamp bulb
carefully and keep out of children
’s
reach. Grasp the bulb by only its
plastic base and do not touch the glass.
The oil from your hand could cause the
bulb to break the next time the headlamps
are operated. Note:
If the bulb is accidentally touched, it
should be cleaned with rubbing alcohol
before being used.

•
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. CLEANING THE INTERIOR WARNINGS
Do not use cleaning solvents, bleach
or dye on the vehicle
’s safety belts,
as these actions may weaken the
belt webbing. On vehicles equipped with
seat-mounted airbags, do not use
chemical solvents or strong
detergents. Such products could
contaminate the side airbag system and
affect performance of the side airbag in a
collision. For fabric, carpets, cloth seats, safety belts
and seats equipped with side airbags:
•
Remove dust and loose dirt with a
vacuum cleaner.
• Remove light stains and soil with
Motorcraft Professional Strength
Carpet & Upholstery Cleaner.
• If grease or tar is present on the
material, spot-clean the area first with
Motorcraft Spot and Stain Remover. In
Canada, use Motorcraft Multi-Purpose
Cleaner.
• If a ring forms on the fabric after spot
cleaning, clean the entire area
immediately (but do not oversaturate)
or the ring will set.
• Do not use household cleaning
products or glass cleaners, which can
stain and discolor the fabric and affect
the flame retardant abilities of the seat
materials.

CLEANING THE INSTRUMENT
PANEL AND INSTRUMENT
CLUSTER LENS
WARNING
Do not use chemical solvents or
strong detergents when cleaning the
steering wheel or instrument panel
to avoid contamination of the airbag
system. Note:
Follow the same procedure as
cleaning leather seats for cleaning leather
instrument panels and leather interior trim
surfaces. See Cleaning Leather Seats
(page 239).
Clean the instrument panel and cluster
lens with a clean, damp and soft cloth,
then use a clean, dry and soft cloth to dry
these areas.
• Avoid cleaners or polishes that increase
the gloss of the upper portion of the
instrument panel. The dull finish in this
area helps protect you from
undesirable windshield reflection.
• Do not use any household cleaning
products or glass cleaners as these
may damage the finish of the
instrument panel, interior trim and
cluster lens.
• Wash or wipe your hands clean if you
have been in contact with certain
products such as insect repellent and
suntan lotion to avoid possible damage
to the interior painted surfaces.
• Do not allow air fresheners and hand
sanitizers to spill onto interior surfaces.
If a spill occurs, wipe off immediately.
Your warranty may not cover these
damages.
If a staining liquid like coffee or juice has
been spilled on the instrument panel or on
interior trim surfaces: 1. Wipe up spilled liquid using a clean,
soft cloth as quickly as possible.
2. Use Motorcraft Premium Leather and Vinyl Cleaner or a commercially
available leather cleaning product for
automotive interiors. Test any cleaner
or stain remover on an inconspicuous
area.
3. Alternatively, wipe the surface with a clean, soft cloth and a mild soap and
water solution. Dry the area with a
clean, soft cloth.
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,
