CHANGING THE 12V BATTERY
WARNING: Batteries normally
produce explosive gases which can
cause personal injury. Therefore, do not
allow flames, sparks or lighted
substances to come near the battery.
When working near the battery, always
shield your face and protect your eyes.
Always provide correct ventilation. WARNING:
When lifting a
plastic-cased battery, excessive pressure
on the end walls could cause acid to flow
through the vent caps, resulting in
personal injury and damage to the
vehicle or battery. Lift the battery with a
battery carrier or with your hands on
opposite corners. WARNING:
Keep batteries out of
reach of children. Batteries contain
sulfuric acid. Avoid contact with skin,
eyes or clothing. Shield your eyes when
working near the battery to protect
against possible splashing of acid
solution. In case of acid contact with skin
or eyes, flush immediately with water for
a minimum of 15 minutes and get prompt
medical attention. If acid is swallowed,
call a physician immediately. WARNING:
Battery posts,
terminals and related accessories
contain lead and lead compounds,
chemicals known to the State of
California to cause cancer and
reproductive harm. Wash your hands
after handling
. The 12V battery is located in the left-hand
side of the luggage compartment. Remove
the door to gain access to the battery.
Your vehicle is fitted with a Motorcraft
maintenance-free battery which normally
does not require additional water.
Note:
After cleaning or replacing the
battery, make sure you reinstall the battery
cover or shield.
When a battery replacement is required,
you must use a recommended
replacement battery that matches the
electrical requirements of the vehicle.
Note: Contact an authorized dealer for low
voltage battery access, testing or
replacement.
To make sure the battery management
system works correctly, do not connect an
electrical device ground connection
directly to the low voltage battery negative
post. This can cause inaccurate
measurements of the battery condition
and potential incorrect system operation.
Note: If you add electrical accessories or
components to the vehicle, it may adversely
affect the low voltage battery performance
and durability. This 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.

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.
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. The clock and radio station
presets are also maintained in memory by
power from the low-voltage battery. These
settings are erased when a technician
disconnects and connects the low-voltage
battery.
To restore the settings, do the following:
1. Apply the parking brake.
2. Shift the transmission into park (P) or neutral (N).
3. Switch off all accessories.
4. Press the brake pedal and start your 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 325). Reset the power
windows bounce-back feature. See
Windows and Mirrors
(page 83).
Reset the radio station presets. See
Audio System
(page 325).
6. Allow the engine to idle for at least one
minute.
7. Drive the vehicle at least 10 mi (16 km)
to completely relearn the idle trim 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.
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.
ADJUSTING THE HEADLAMPS
Vertical Aim Adjustment
The headlamps on your vehicle are
properly aimed at the assembly plant. If
your vehicle has been in an accident, the
alignment of your headlamps should be
checked by your authorized dealer.

Vertical Aim Adjustment Procedure
1. Park the vehicle directly in front of a
wall or screen on a level surface,
approximately 25 ft (7.6 m) away.
2. Measure the height of the headlamp bulb center from the ground and mark
an
8 ft (2.4 m) horizontal reference line
on the vertical wall or screen at this
height.
Note: To see a clearer light pattern for
adjusting, you may want to block the light
from one headlamp while adjusting the
other.
3. Turn on the low beam headlamps to illuminate the wall or screen and open
the hood. 4. On the wall or screen you will observe
a flat zone of high intensity light
located at the top of the right hand
portion of the beam pattern. If the top
edge of the high intensity light zone is
not at the horizontal reference line, the
headlamp will need to be adjusted. 5. Locate the vertical adjuster on each
headlamp. Using a Phillips #2
screwdriver, turn the adjuster either
clockwise or counterclockwise in order
to adjust the vertical aim of the
headlamp. The horizontal edge of the
brighter light should touch the
horizontal reference line.
6. Close the hood and turn off the lamps.
Horizontal Aim Adjustment
Horizontal aim is not required for this
vehicle and is not adjustable.
WASHER FLUID CHECK WARNING:
If you operate your
vehicle in temperatures below 40°F
(5°C), use washer fluid with antifreeze
protection. Failure to use washer fluid
with antifreeze protection in cold
weather could result in impaired
windshield vision and increase the risk
of injury or accident.
Add fluid to fill the reservoir if the level is
low. Only use a washer fluid that meets
Ford specifications. See
Capacities and
Specifications (page 310).

Fusion Energi (CC7) Hybrid Electric Vehicle (HEV)/Plug-In Hybrid Electric Vehicle (PHEV), Canada/United States of America, enUSA, Edition date: 201905, Second-Printing MaintenanceE142465 E145594

State or local regulations on volatile
organic compounds may restrict the use
of methanol, a common windshield washer
antifreeze additive. Washer fluids
containing non-methanol antifreeze
agents should be used only if they provide
cold weather protection without damaging
the vehicle
’s paint finish, wiper blades or
washer system.
FUEL FILTER
Your vehicle is equipped with a lifetime
fuel filter that is integrated with the fuel
tank. Regular maintenance or replacement
is not needed.
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
The wiper arms can be manually moved
when the ignition is off. This allows for ease
of blade replacement and cleaning under
the blades.
1. Pull the wiper blade and arm away
from the glass. Press the locking
buttons together.
2. Rotate and remove the wiper blade.
3. Install in the reverse order.
Note: Make sure that the wiper blade locks
into place. Lower the wiper arm and blade
back to the windshield. The wiper arms will
automatically return to their normal position
when the ignition is turned on.
Replace wiper blades at least once per
year for optimum performance.
Poor wiper quality can be improved by
cleaning the wiper blades and the
windshield.
