COOLANT
Checking the Coolant
When the Electric Powertrain Assembly is cold, check the level of the
coolant in the reservoir at the intervals listed in thescheduled
maintenance information.
Note:Make sure that the level is between the MIN and MAX marks on
the coolant reservoir.
Note:Coolant expands when it is hot. The level may extend beyond the
MAX mark.
Note:If the coolant has not been checked at the recommended interval,
the coolant reservoir may become low or empty. If the level is at the MIN
mark, below the MIN mark, or empty, add prediluted coolant to the
reservoir. SeeAdding coolantin this chapter.
Note:For best results, coolant concentration should be tested with a
refractometer such as Rotunda tool 300-ROB75240E available from your
dealer. Ford does not recommend the use of hydrometers or coolant test
strips for measuring coolant concentrations.
Note:It is very important to use prediluted coolant meeting the Ford
specification in order to avoid plugging the small coolant passageways.
Use of concentrated coolant and water may cause coolant passageway
plugging and void the warranty. See the technical specifications chart in
theCapacities and Specificationschapter.
Note:Automotive fluids are not interchangeable; do not use
coolant/antifreeze or windshield washer fluid outside of its specified
function and vehicle location.
Adding Coolant
WARNING:Do not add coolant when the Electric Powertrain
Assembly 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 motor parts.
WARNING:Do not put coolant in the windshield washer fluid
container. If sprayed on the windshield, coolant could make it
difficult to see through the windshield.

Owners Guide gf, 1st Printing, May 2013
USA(fus)

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 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.
Note:If the coolant reservoir is lower than the MIN mark, then coolant
should be added. Do not add coolant above 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 or
additives as they can cause damage to the cooling 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 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.

Transmission
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.
BRAKE FLUID CHECK
Note:Keep brake fluid clean. Contamination with dirt, water, petroleum
products or other materials may result in brake system damage and
possible failure.
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.
POWER STEERING FLUID CHECK
Your vehicle is equipped with an electric power steering (EPS) system.
There is no fluid reservoir to check or fill. For additional information on
the electric power steering (EPS) system, Refer toDriving Aids.
WINDSHIELD WASHER FLUID
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. In very cold weather, do
not fill the reservoir completely.
Maintenance215
2014 Focus Electric Vehicle(fob)
Owners Guide gf, 1st Printing, May 2013

Only use a washer fluid that meets Ford specifications. Do not use any
special washer fluid such as windshield water repellent type fluid or bug
wash. They may cause squeaking, chatter noise, streaking and smearing.
SeeTechnical Specificationsin theCapacities and Specifications
chapter.
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.
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
