2013 MITSUBISHI iMiEV cooling

WARNING
l If electrolyte fluid is not visible, or ap-
pears to be frozen, Do Not Attempt Jump
Starting!
A battery might rupture or explode if the
temperature is below the freezing point
or if it is not filled to the proper level.
7. Connect
one end of one jumper cable to the positive (+) terminal of the discharged bat-
tery (A), and the other end to the positive (+)
terminal of the booster battery (B).
Connect one end of the other jumper cable to
the negative (-) terminal of the booster bat-
tery, and the other end to the designated loca-
tion of the vehicle with the discharged bat-
tery at the point farthest from the battery. WARNING
l Make
sure you observe the following or-
der when connecting the cables: → →
→
l
Make sure you make connection to the
correct

designated location (as shown in
the illustration). If the connection is made
directly to the negative (-) side of the dis-
charged battery, flammable gases gener-
ated from the battery might catch fire
and explode.
l When connecting the jumper cables, do
not connect the positive (+) cable to the
negative (-) terminal. Otherwise sparks
might cause explosion of the battery. CAUTION
l
Take
care not to get the jumper cable
caught in the cooling fan or other rotat-
ing part in the bonnet room or engine com-
partment.
l Use the proper cables suitable for the bat-
tery size to prevent overheating of the ca-
bles.
l Check the jumper cables for damage and
corrosion before use.
8. Start
the engine in the vehicle which has the booster battery, let the engine idle a few mi-
nutes, then start the electric motor unit in the
vehicle with the discharged battery.
9. Check that the ready indicator illuminates.

[When the ready indicator illuminates]
Stop

the engine of another vehicle, discon-
nect the cables in the reverse order and
charge the auxiliary battery for more than 30
minutes.
After the auxiliary battery is charged, contin-
ue the process from step 16.

[When the ready indicator does not illuminate]
Both the auxiliary battery and the traction bat-
tery have gone flat at the same time.
Charge the auxiliary battery and the traction
battery by the following procedures (from
steps 10 to 14).

10. Keep connecting the jumper cable to each ve- hicle, turn the electric motor switch of your
vehicle to the “LOCK” position.
NOTE l The jumper cable needs to be connected to
the auxiliary battery when you start charging
the traction battery because the on board
charger etc. operate with a power source of
auxiliary battery.
11. Charge the traction battery by regular charg- ing. (Refer to “Regular charging” on page
1-08.)
12. When the charging indicator on the instru- ment cluster is illuminated, stop the engine
of another vehicle, disconnect the cables in
the reverse order. For emergencies

While the motor is cold, the coolant level
must
always be between the “F (FULL)” and
the “L (LOW)” marks.
FULL
LOW 5. Refit
the electric motor unit room lid and the
luggage floor carpet by following the remov-
al procedures in reverse.
Hot water heater fluid
A transparent reserve tank (A) is located in the bon-
net room.
The coolant level in this tank should be kept be-
tween the “FULL” and “LOW” marks when meas-
ured while the electric motor is cold.
FULL
LOW To add coolant
The

cooling system is a closed system and normal-
ly the loss of coolant should be very slight. A no-
ticeable drop in the coolant level could indicate leak-
age. If this occurs, we recommend you to have the
system checked as soon as possible.
If the level should drop below the “LOW” level on
the reserve tank, open the reserve tank cap (E) and
add coolant. WARNING
l Do
not open the reserve tank cap (E)
while it is hot. The coolant system is un-
der pressure and any hot coolant escap-
ing could cause severe burns.
Anti-freeze
The
coolant contains an ethylene glycol anti-corro-
sion agent. Some parts of the electric motor are
cast aluminium alloy, and periodic changing of the
electric motor coolant is necessary to prevent corro-
sion of these parts.

Use “MITSUBISHI MOTORS GENUINE SUPER
LONG LIFE COOLANT PREMIUM” or equiva-
lent*.
*: similar high quality ethylene glycol based non-
silicate, non-amine, non-nitrate and non-borate cool-
ant with long life hybrid organic acid technology

MITSUBISHI MOTORS GENUINE Coolant has
excellent protection against corrosion and rust for-
mation of all metals including aluminium and can
avoid blockages in the radiator, heater, etc. Because of the necessity of this anti-corrosion
agent,

the coolant must not be replaced with plain
water even in summer. The required concentration
of anti-freeze differs depending on the expected am-
bient temperature.

Above -35 °C: 50 % concentration of anti-freeze
Below -35 °C: 60 % concentration of anti-freeze CAUTION
l
Do
not use alcohol or methanol anti-
freeze or any engine coolants mixed with
alcohol or methanol anti-freeze. The use
of an improper anti-freeze can cause cor-
rosion of the aluminium components.
l Do not use water to adjust the concentra-
tion of coolant.
l Concentrations exceeding 60 % will re-
sult in a reduction of both the anti-freeze
and cooling performance.
l Do not top up with water only.
Water by itself reduces the rust-protec-
tive and anti-freeze qualities of the cool-
ant and has a lower boiling point. It can
also cause damage to the cooling system if
it should freeze. Do not use tapwater, as it
can cause corrosion and rust formation.
During cold weather
If
the temperatures in your area drop below freez-
ing, there is the danger that the coolant in the elec-
tric motor, on board charger/DC-DC converter or
radiator could freeze and cause severe damage to
the electric motor, on board charger/DC-DC con-
verter and/or radiator. Add a sufficient amount of
anti-freeze to the coolant to prevent it from freezing. Vehicle care and Maintenance

The brake fluid in the master cylinder should be
checked
when doing other work under the bonnet.
The brake system should also be checked for leak-
age at the same time.
If the brake fluid level falls markedly in a short
length of time, it indicates leaks from the brake sys-
tem.
If this occurs, we recommend you to have the vehi-
cle checked.
Fluid type
Use brake fluid conforming to DOT3 or DOT4
from a sealed container. The brake fluid is hygro-
scopic. Too much moisture in the brake fluid will
adversely affect the brake system, reducing the per-
formance. CAUTION
l
Take
care in handling brake fluid as it is
harmful to the eyes, may irritate your
skin and also damage painted surfaces.
l Use only the specified brake fluid.
Do not mix or add different brands of
brake fluid to prevent chemical reactions.
Do not let any petroleum-based fluid
touch, mix with, or get into the brake fluid.
This will damage the seals.
l Keep the reservoir tank cap closed to pre-
vent the brake fluid from deteriorating ex-
cept maintenance.
l Clean the filler cap before removing and
close the cap securely after maintenance. Auxiliary battery

The

condition of the auxiliary battery is very impor-
tant to keep the vehicle’s electrical system working
properly. Regular inspection and care are especial-
ly important in cold weather.
Removing and installing the auxiliary
battery upper cover E08402400012
To remove 1. Turn
the plastic nut (A) anticlockwise, and
then remove the auxiliary battery upper cov-
er (B). NOTE
l Be

careful not to lose the removed plastic nut. To install
1. Install
the auxiliary battery upper cover (B)
onto the auxiliary battery, and then push the
plastic nut (A) in the direction shown by the
arrows to secure the cover. CAUTION
l
Be sure to install the auxiliary battery up-
per

cover. Otherwise, the battery electro-
lyte may spill and cause a malfunction.
l When installing the auxiliary battery up-
per cover and plastic nut do not touch the
cooling fan or other moving parts in the
bonnet room.
Be especially careful that the cables, your
clothing or hair, etc., do not get caught in
the cooling fan or other moving parts.
NOTE l Be

sure to install the plastic nut in the correct
direction. Vehicle care and Maintenance
