Adequate
care of your vehicle at regular intervals
serves to preserve the value and appearance as long
as possible.
Maintenance items as described in this owner’s man-
ual can be performed by the owner.
We recommend you to have the periodic inspection
and maintenance performed by a MITSUBISHI
MOTORS Authorized Service Point or another spe-
cialist.
In the event a malfunction or a problem is discov-
ered, we recommend you to have it checked and re-
paired. Follow the instructions and cautions for
each of the various procedures. WARNING
l Do
not touch any components in the elec-
tric motor unit room other than the re-
serve tank. There are no components re-
quiring inspection other than the reserve
tank. Never remove or disassemble the
component which generates high voltage,
high voltage wire (orange) and its connec-
tor. Doing so could result in serious in-
jury that may risk your life.

Coolant/Hot water heater fluid
E08402100019
To check the coolant level
Coolant 1.
Open the tailgate. 2. Peel
off the Velcro fastener (A) to remove
the luggage floor carpet (B). NOTE
l A

heat insulating material is attached to the
luggage floor carpet. To remove the luggage
floor carpet, grab and lift up both the carpet
fabric and the heat insulating material.
3. Turn the 4 screws on the front and rear of the electric motor unit room lid (C) anticlock-
wise to loosen and remove them, and then re-
move the electric motor unit room lid (C). NOTE
l When

laying the electric motor unit room lid
on the ground, leave the underside of the lid
with the rubber surface facing up. If the un-
derside is facing downward rubbish and oth-
er foreign material could get on the rubber
surface and prevent proper reinstallation of
the electric motor unit room lid.
4. Check the coolant level in the reservoir tank (D). While the motor is cold, the coolant level
must

always be between the “FULL” and
“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.

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 “DIA QUEEN SUPER LONG LIFE COOL-
ANT PREMIUM” or equivalent*.
*: 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 Genuine Coolant has excellent pro-
tection against corrosion and rust formation of all
metals including aluminium and can avoid block-
ages 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. The concentration should be checked before the
start

of cold weather and anti-freeze added to the
system if necessary. Vehicle care and Maintenance

Washer fluid
E08402200010
Check
if the fluid level is between the “FULL” and
“1/2” on the washer fluid reservoir.
If the level is low, replenish the container with wash-
er fluid.
FULL NOTE
l The

washer fluid container serves the wind-
screen, rear window.
During cold weather
To ensure proper operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Brake fluid
E08406100017
To check the fluid level
The

brake fluid level must be between the “MAX”
and “MIN” marks on the reservoir. The brake fluid level is monitored by a float. When
the

brake fluid level falls below the “MIN” mark,
the brake fluid warning lamp lights up.
The fluid level falls slightly with wear of the brake
pads, but this does not indicate any abnormality.
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. Vehicle care and Maintenance

Auxiliary battery
E08402300011
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. Checking auxiliary battery electrolyte
level
E08402500013 Before checking the auxiliary battery electrolyte lev-
el, remove the auxiliary battery’s upper cover.
The

electrolyte level must be between the specified
limit on the outside of the auxiliary battery. Replen-
ish with distilled water as necessary.
The inside of the auxiliary battery is divided into
several compartments; remove the cap from each
compartment and fill to the upper mark. Do not top
up beyond the upper mark because spillage during
driving could cause damage.
Check the electrolyte level at least once every 4
weeks, depending on the operating conditions.
If the auxiliary battery is not used, it will discharge
by itself with time.
Check it once every four weeks and charge with
low current if necessary. Vehicle care and Maintenance

During cold weather
E08402600014
The
capacity of the auxiliary battery is reduced at
low temperatures. This is an inevitable result of its
chemical and physical properties. This is why a
very cold auxiliary battery, particularly one that is
not fully charged will only deliver a fraction of the
starting current which is normally available.
We recommend you to have the auxiliary battery
checked before the start of cold weather and, if nec-
essary, have it charged or replaced.
This does not only ensure reliable starting, but an
auxiliary battery which is kept fully charged also
has a longer life.
Disconnection and connection E08402700015
To disconnect the auxiliary battery cable, stop the
electric

motor unit, first disconnect the negative (-)
terminal and then the positive (+) terminal. When
connecting the auxiliary battery, first connect the
positive (+) terminal and then the negative (-) termi-
nal.
NOTE
l Open the terminal cover (A) before discon-
necting or connecting the positive (+) termi-
nal of the auxiliary battery.
l Loosen the nut (B), and then disconnect the
auxiliary battery cable from the positive (+)
terminal. WARNING
l Keep sparks, cigarettes, and flames away
from the auxiliary battery because the
auxiliary battery could explode.
l When installing the auxiliary battery,
start connection with the positive (+) ter-
minal. If connection is started from the
negative (-) terminal, sparks will occur if
the positive (+) terminal touches any oth-
er parts, and this may cause the auxiliary
battery to explode.
l The auxiliary battery electrolyte is ex-
tremely caustic. Do not allow it to come
in contact with your eyes, skin, clothing,
or the painted surfaces of the vehicle.
Spilt electrolyte should be flushed imme-
diately with ample amounts of water.
Irritation to eyes or skin from contact
with electrolyte requires immediate medi-
cal attention.
l Ventilate when charging or using the aux-
iliary battery in an enclosed space. CAUTION
l
Keep it out of reach of children.
l When

replacing the auxiliary battery, re-
move the connected positive (+) and nega-
tive (-) terminals after turning the electric
motor switch to the “LOCK” position
and waiting at least 1 minute. If the auxil-
iary battery terminal is removed just af-
ter the electric motor switch is turned to
the “LOCK” position, this may cause dam-
age to components of the electric motor
unit.
l Never short-circuit the auxiliary battery.
This could cause it to overheat and be dam-
aged.
l If the auxiliary battery is to be quick-
charged, first disconnect the battery ca-
bles.
l In order to prevent a short circuit, be
sure to disconnect the negative (-) termi-
nal first.
l Always wear protective eye goggles when
working near the auxiliary battery.
l Do not bring the nearby parts, the plastic
parts and so on into contact with sulphu-
ric acid (battery electrolyte) which may
crack, stain or discolour them.
If they are in contact, wipe off with soft
cloth, chamois or the like and an aqueous
solution of neutral detergent then imme-
diately rinse the affected parts with plen-
ty of water. Vehicle care and Maintenance
