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.

Note:Electrical or electronic accessories or components added to the
vehicle by the dealer or the owner may adversely affect battery
performance and durability and may also affect the performance of other
electrical systems in the vehicle.
When a battery replacement is required, the battery should only be
replaced with a Ford recommended replacement battery that matches
the electrical requirements of the vehicle.
Note: The clock and the preset radio stations must be reset once the
battery is reconnected.
•Always dispose of automotive
batteries in a responsible manner.
Follow your local authorized
standards for disposal. Call your
local authorized recycling center
to find out more about recycling
automotive batteries.
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.

HIGH-VOLTAGE SERVICE DISCONNECT
The high-voltage service disconnect shuts off power from the
high-voltage battery.
Disabling the High-Voltage Battery
Note:There are two disconnect circuits in your vehicle. Disconnecting
one circuit will automatically disable the high-voltage battery.
To disable the high-voltage battery and stop all high-voltage electric
activity in the vehicle you can access one or both of the two high-voltage
disconnect circuits. To do this, you must unplug one of the circuits from
the circuit ports connected to the battery.
The lower battery high-voltage disconnect circuit is located by the right
rear wheel, accessible from under the car.
The upper battery high-voltage disconnect circuit is located behind the
rear fold-down seats near the left side of the vehicle, and is more easily
accessible than the lower battery circuit. To access this circuit:
1. Fold down the left rear seat.
2. Locate the access door. Press the
button on the top of the access
door to remove the plastic cover.
3. A cut out area will be visible
which allows your hand access to
the circuit.
4. Press the tab on the top center of
the circuit and rotate the handle
toward you. Press again to pull the
hand down.
5. Pull the handle toward you and remove the circuit from the vehicle to
disable the high-voltage battery.
Reactivating the High-Voltage Battery
Note: If you have manually disconnected your high-voltage shutoff
circuits you will need to reconnect the circuits before they can be
reactivated. The vehicle will detect if the electrical system is safe and
reactivate automatically.

WARNING:In an emergency, add water to the cooling system to
reach an authorized dealer. Have the system checked by a
properly trained technician as soon as possible.
WARNING: To reduce the risk of personal injury, make sure the
Electric Powertrain Assembly (EPA) 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.
WARNING: Do not add coolant further than the MAX mark.
Note: Coolant replacement can only be completed by an authorized
dealer. If not performed properly, damage could occur to the cooling
system components and may void the warranty.
Note: Do not use stop leak pellets or cooling system sealants/additives
as they can cause damage to the cooling and/or heating systems. This
damage would not be covered under your vehicle’s warranty.
Note: During normal vehicle operation, the coolant may change color
from orange to pink or light red. As long as the coolant is clear and
uncontaminated, this color change does not indicate the coolant has
degraded nor does it require the coolant to be drained, the system to be
flushed, or the coolant to be replaced.
• DO NOT MIX different colors or types of coolant in your vehicle. Make
sure the correct coolant is used. Mixing of coolants may harm your
cooling system. The use of an improper coolant may harm the Electric
Powertrain Assembly (EPA) and cooling system components and may
void the warranty.
• A large amount of water without coolant may be added, in case of
emergency, to reach a vehicle service location. In this instance, the
cooling system must be drained, chemically cleaned with Motorcraft 
Premium Cooling System Flush, and refilled with prediluted coolant as
soon as possible. Water alone (without coolant) can cause damage
from corrosion, overheating, freezing or plugging.
• Do not use alcohol, methanol, brine or any coolants mixed with
alcohol or methanol antifreeze (coolant). Alcohol and other liquids can
cause damage from overheating or freezing.
• Do not add extra inhibitors or additives to the coolant. These can be
harmful and compromise the corrosion protection of the coolant.

BRAKE FLUID CHECK
The fluid level will drop slowly as the
brakes wear, and will rise when the
brake components are replaced. Fluid
levels between the MIN and MAX
lines are within the normal operating
range; there is no need to add fluid.
If the fluid levels are outside of the
normal operating range, the
performance of the system could be
compromised; seek service from your
authorized dealer immediately.
Note:Keep brake fluid clean. Contamination with dirt, water, petroleum
products or other materials may result in brake system damage and
possible failure.
Checking single-speed transmission
The transmission does not have an underhood transmission fluid dipstick.
Your transmission does not consume fluid. It is designed to be filled for
life. However, the fluid level should be checked if the transmission is not
working properly, or if you notice some sign of fluid leakage.
Note: Transmission fluid should be checked and, if required, fluid should
be added by an authorized dealer.
Do not use supplemental transmission fluid additives, treatments or
cleaning agents. The use of these materials may affect transmission
operation and result in damage to internal transmission components.
VEHICLE STORAGE
If you plan on storing your vehicle for an extended period of time
(30 days or more), refer to the following maintenance recommendations
to ensure your vehicle stays in good operating condition.
All motor vehicles and their components were engineered and tested for
reliable, regular driving. Long term storage under various conditions may
lead to component degradation or failure unless specific precautions are
taken to preserve the components.
General
• Store all vehicles in a dry, ventilated place.
• Protect from sunlight, if possible.
• If vehicles are stored outside, they require regular maintenance to
protect against rust and damage.
