Check the 12V starter battery, including terminals and
cables. During extremely cold weather, the 12V starter
battery will not be as strong and its power level may drop.
Before driving the vehicle, check to see if the headlights
are as bright as normal. Charge or replace the 12V starter
battery if necessary. During extreme cold weather, it is
possible that a very low 12V starter battery could freeze.
Check the antifreeze.
If there is not enough coolant because of a leak, add high-
quality ethylene glycol antifreeze and water. Use Dia
Queen Super Long Life Coolant Premium or an equiva-
lent. The recommended blend is about 50 % water and 50
% anti-freeze. Use a higher concentration (not over 60 %)
when the outside temperature is -31 °F (-35 °C) or lower.
When the electric motor unit is working very hard (for
example, during mountain driving and/or when the out-
side temperature is high), use a 50 % concentration. This
blend will provide adequate protection from corrosion and
boiling.

!
The 12V starter battery gives off explosive hydrogen
gas. Any spark or flame can cause the 12V starter
battery to explode, which could cause serious injury
or death.
Always wear protective clothes and a face mask
when working with your 12V starter battery, or let a
skilled mechanic do it.
WA R N I N G
!
Never open the coolant reservoir cap while it is hot.
You could be seriously burned.

Have you purchased the Mitsubishi Motors Diamond Care Pro-
tection Plan? The Plan supplements your new vehicle warran-
ties. See a certified i-MiEV dealer for details.

!
When servicing the vehicle, make sure that the elec-
tric motor switch is in the “LOCK” position and the
charging cable is disconnected. Failure to do so
could result in an electric shock.
When checking or servicing under the hood or the
coolant reserve tank, be sure the electric motor unit
is stopped and it has had a chance to cool down.
If you need to work under the hood with the electric
motor unit on, be careful that your clothing, hair,
etc. does not get caught in the fan or other moving
parts.
The fan can turn on automatically even if the elec-
tric motor unit is not running. Turn the electric
motor switch to the “LOCK” position to be safe
while you are working under the hood.
Do not smoke or allow open flames around the 12V
starter battery.
Be extremely careful when working around the 12V
starter battery. It contains poisonous and corrosive
sulfuric acid.
Handling your vehicle’s parts and materials in the
wrong way can injure you. Ask a certified i-MiEV
dealer if you have questions.
CAUTION
!
The components inside the electric motor unit room
may be very hot to the touch.
Make sure all components have sufficiently cooled
before beginning an inspection.
These components are affixed with a label indicating
precautions for handling. Follow the instructions on
the label.
When replacing the 12V starter battery, remove the
positive (+) and negative (-) terminals after turning
the electric motor switch to the “LOCK” position
and waiting at least 2 minutes. If the 12V starter
battery terminal is removed just after the electric
motor switch is turned to the “LOCK” position, this
may cause damage to electric components.
If the electric motor unit warning light illuminates,
do not replace the 12V starter battery. Contact a
certified i-MiEV dealer.

Before checking the coolant level, make sure the
electric motor switch is in the “Lock” position to
avoid the risk of an electrical shock that can result in
serious injury or death.
The room under the hood and the electric motor
unit room (located under the luggage room carpet)
can be very hot after driving. Wait until they have
cooled down.

4. Check the coolant level in the reservoir (D).
While the motor is cold, the coolant level must always be
between the “F (FULL)” and the “L (LOW)” marks. If
necessary, add coolant. Refer to “To add coolant” on page
7-10.
5. Reinstall the electric motor unit room lid and the luggage
room floor carpet by following the removal procedures in
reverse.
Hot water heater fluidThe reservoir (A) is located under the hood.
The coolant level in this reservoir should be kept between the
“F (FULL)” and the “L (LOW)” marks when measured while
the electric motor is cold. If necessary, add coolant. Refer to
“To add coolant” on page 7-10.

To add coolant
N00955900011
Mitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum.
If you need to add coolant often, the cooling system should be
pressure-tested for leaks. Take your vehicle to a certified i-
MiEV dealer for testing.
Reservoir cap
N00955800010
The reservoir cap (E) must be tightly sealed to prevent losing
coolant which may result in electric motor or nearby parts of
the room under the hood damage. Only use a Genuine
Mitsubishi Parts reservoir cap, or an approved equivalent.
Use “Dia Queen Super Long Life Coolant Premium” or an
equivalent*.
*: similar high quality ethylene glycol based non-silicate, non-
amine, non-nitrate and non-borate coolant with long life
hybrid organic acid technology
CAUTION
!
Do not use alcohol or methanol antifreeze or any
coolants that contain them. Using the wrong anti-
freeze can corrode aluminum parts.
The required concentration of anti-freeze differs
depending on the expected ambient temperature.
Above -31 °F (-35 °C): 50 % concentration of anti-
freeze
Below -31 °F (-35 °C): 60 % concentration of anti-
freeze
You can check the concentration level with a gauge
from an automotive supply store, or a certified i-
MiEV dealer or service station can check it for you.
Do not use water to adjust the concentration of cool-
ant.

Do not top off the tank with plain water only. Water
by itself boils at a lower temperature and does not
stop rust or freezing. If the water freezes, it will
damage your cooling system. Do not use tap water. It
can cause corrosion and rust.
WA R N I N G
!
Wait for the electric motor to cool down before
opening the reservoir cap. Otherwise hot steam or
boiling coolant could spray up from the reservoir
and scald you.
