Poor wiper quality can be improved by cleaning the wiper blades and the
windshield. Refer to theVehicle Carechapter.
To prolong the life of the wiper blades, it is highly recommended to
scrape off the ice on the windshield before turning on the wipers. The
layer of ice has many sharp edges and can damage the micro edge of the
wiper rubber element.
Changing the rear window wiper blade (if equipped)
To replace the rear wiper blade:
1. Press the wiper blade against the
glass with one hand and hold it.
2. Pull the wiper arm away from the
wiper blade to separate.
3. To attach the new wiper to the
wiper arm, align the slot (1) and
cross pin (2) and firmly press the
wiper arm into the wiper blade until
a click is heard.
If you find this procedure too difficult, please see your dealer.
LOW-VOLTAGE 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
proper 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/or 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. Wash hands after handling.
Your vehicle is equipped with a
Motorcraftmaintenance-free
battery which normally does not
require additional water during its
life of service.
Note: If your battery has a cover/shield, make sure it is reinstalled after
the battery has been cleaned or replaced.
For longer, trouble-free operation, keep the top of the battery clean and
dry. Also, make certain the battery cables are always tightly fastened to
the battery terminals.
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.
It is recommended that the negative battery cable terminal be
disconnected from the battery if you plan to store your vehicle for an
extended period of time. This will minimize the discharge of your battery
during storage.
To ensure proper operation of the battery management system (BMS), any
electrical devices that are added to the vehicle should not have their
ground connection made directly at the negative battery post. A connection
at the negative battery post can cause inaccurate measurements of the
battery condition and potential incorrect system operation.

HIGH-VOLTAGE BATTERY
WARNING: This battery pack should only be serviced by an
authorized electric vehicle technician. Improper handling can
result in personal injury or death.
Your vehicle consists of various high-voltage components and wiring. All
of the high-voltage power flows through specific wiring assemblies which
are labeled as such and/or are covered with a solid orange convolute or
orange striped tape. Do not come in contact with these components.
No regular maintenance, other than regular charging is required.
The high-voltage battery system is a high-voltage, lightweight lithium-ion
battery system comprised of two individual packs. One pack is located in
the rear cargo area behind the second row seats, and the other is located
underneath the vehicle. The high-voltage battery system uses an advanced,
active liquid heating and cooling system to regulate high-voltage battery
temperature and help maximize high-voltage battery life.

CHARGING THE HIGH-VOLTAGE BATTERY
WARNING:Do not use the 120 volt convenience cord with an
extension cord or adapter.
WARNING: In Canada, do not use the 120 volt convenience cord
in commercial garages.
WARNING: This equipment has arcing or sparking parts that
should not be exposed to flammable vapors. This equipment
should be located at least 18 inches (80 mm) above the floor.
Charging Equipment
Note: Your vehicle comes equipped with a standard 120 volt
convenience cord located in your trunk storage compartment underneath
the carpeted panel. This allows you to charge the battery in your own
garage using a standard 120 volt household outlet. Using the standard
120 volt convenience cord takes up to 18–20 hours to completely charge
from an empty battery.
Ford recommends upgrading to the
optional 240 volt charging station
for faster more efficient charging.
Use of a 240 volt charging station
will take approximately 3–4 hours to
fully charge a empty battery.
Note: Your electrical source must meet certain requirements for the
high-voltage battery to charge. The AC outlet must be a three-prong
110-120 volt AC outlet that is properly grounded, 15–20 amps (or
greater), and in good condition. The line also must be dedicated, which
means that no other appliances should be connected to the same circuit.
If a dedicated circuit is not used, the circuit breaker could trip or open.
If a dedicated circuit is not available, contact a licensed professional
electrician for proper installation.

power, charge and fault.
The charge port is located between the front left side door and front left
wheel well. There is an indentation located on the charge port door that
allows you to press to open and press to close the door.
Power (green light) — this indicator lights up when the cord is plugged
into the AC wall outlet.
Charge (green light) — Indicates status of charging:
• No light means the cord is not connected to the vehicle.
• Blinking light means that the charging is in process.
• Solid light means that the vehicle is connected but not charging.
Fault (red triangle light) — Lights up in case of a detected failure. No
charging is possible:
• Blinking red triangle light – means that the 120 volt convenience cord
is trying to reset the failure and could restart the charging cycle.
• Solid red triangle light – means that the fault is permanent. The cord
needs to be unplugged and re-plugged to reset the fault. If the fault
persists, contact your authorized dealer.
