authorized dealer as soon as possible.
LOW Engine Oil Pressure
Displayed when the engine oil life remaining is 10% or less. See Engine Oil Check (page 288).
Change Engine Oil Soon
Displayed when the oil life left reaches 0%.
See Engine Oil Check (page 288).
Oil Change Required
Indicates the brake fluid level is low and the brake system should be inspected immediately.See
Brake Fluid Check (page 294).
Brake Fluid Level LOW
Displays when the brake system needs servicing. Stop the vehicle in a safe place. Contact your authorized dealer.
Check Brake System
Displays when the engine coolant temperature is excessively high. Stop the vehicle in a safeplace and contact your authorized dealer.
Engine Coolant Overtemperature
Displays when the motor electronics are overheating. Stop the vehicle as soon as safely possible,
turn off the vehicle and let it cool. If the warning stays on or continu\
es to come on, contact yourauthorized dealer as soon as possible.
Motor Coolant Overtemperature
Displays when the washer fluid is low and needs to be refilled.
Washer Fluid Level Low

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 346).
3. Replace the filler cap. Turn it until you feel a strong resistance. ENGINE COOLANT CHECK
Engine Coolant and Inverter System
Controller Coolant
Your vehicle is equipped with 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 468).
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.
The coolant concentration should be
maintained 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.

•
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.
• 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
fluid.
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.

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.
• Check fluid levels (including coolant, oil
and gas) to make sure there are no leaks,
and fluids are at recommended levels.
• If you remove the battery, clean the
battery cable ends and inspect.
Contact an authorized dealer if you have any
concerns or issues.

Make sure to change your vehicle
’s oils and
fluids at the specified intervals or in
conjunction with a repair. Flushing is a viable
way to change fluid for many vehicle
sub-systems during scheduled maintenance. It is critical that systems are flushed only with
new fluid that is the same as that required
to fill and operate the system or using a
Ford-approved flushing chemical.
Owner Checks and Services
Make sure you perform the following basic
maintenance checks and inspections every
month or at six-month intervals. Check every month
Engine oil level.
Function of all interior and exterior lights.
Tires (including spare) for wear and proper pressure. Windshield washer fluid level. Check every six months
Battery connections. Clean if necessary.
Body and door drain holes for obstructions. Clean if necessary. Cooling system fluid level and coolant strength.
Door weatherstrips for wear. Lubricate if necessary.
Hinges, latches and outside locks for proper operation. Lubricate if necessary. Parking brake for proper operation.
