E01000100878
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. This section contains information on inspec-
tion maintenance procedures that you can do your-
self. Follow the instructions and cautions for each
of the various procedures. WARNING
l When
checking or servicing the inside of
the engine compartment, make sure the
engine is switched off and has had a
chance to cool down.
l If it is necessary to do work in the engine
compartment with the engine running, be
especially careful that your clothing, hair,
etc., does not become caught by the fan,
drive belts, or other moving parts.
l The fan may turn on automatically even
if the engine is not running. Turn the igni-
tion switch to the “LOCK” position or
put the operation mode in OFF to be safe
while you work in the engine compart-
ment. WARNING
l Do
not smoke, cause sparks or allow open
flames around fuel or battery. The fumes
are flammable.
l Be extremely cautious when working
around the battery. It contains poisonous
and corrosive sulphuric acid.
l Do not get under your vehicle with just
the body jack supporting it. Always use
automotive jack stands.
l Improper handling of components and
materials used in the vehicle can endan-
ger your personal safety. We recommend
you to consult a specialist for necessary in-
formation. Catalytic converter
E01000200765
The

exhaust gas scavenging devices used with the
catalytic converter are extremely efficient for the re-
duction of noxious gases. The catalytic converter is
installed in the exhaust system.
It is important to keep the engine properly tuned to
ensure proper catalyst operation and prevent possi-
ble catalyst damage. WARNING
l As
with any vehicle, do not park or oper-
ate this vehicle in areas where combusti-
ble materials such as dry grass or leaves
can come in contact with a hot exhaust
since a fire could occur.
l Paint should not be applied to the catalyt-
ic converter.
NOTE l Use

fuel of the type recommended in “Fuel
selection” on page 02. Maintenance

The engine oil used has a significant effect on the
engine’s

performance, service life and startability.
Be sure to use oil of the recommended quality and
appropriate viscosity.
All engines consume a certain amount of oil during
normal operation. Therefore, it is important to
check the oil level at regular intervals or before start-
ing a long trip. 1. Park the car on a horizontal surface.
2. Switch off the engine.
3. Wait a few minutes.
4. Remove the dipstick and wipe it with a cleancloth.
5. Reinsert the dipstick as far as it goes.
6. Remove the dipstick and read the oil level, which should always be within the range in-
dicated.
7. If the oil level is below the specified limit, re- move the cap located on the cylinder head
cover and add enough oil to raise the level to
within the specified range. Do not overfill to
avoid engine damage. Be sure to use the speci-
fied engine oil and do not mix various types
of oil. Maintenance

8. After adding oil, close the cap securely.
9.
Confirm the oil level by repeating step 4 to 6. CAUTION
l
In
diesel-powered vehicles, when burning
away and removing soot accumulated in
the DPF, fuel can mix with the engine oil
and an increase in the engine oil level
may occur. This does not indicate an ab-
normality.
However, if the engine oil level is at or
over the “X” mark (B) on the engine oil
dipstick (A), change the engine oil.
MAX. MIN. NOTE
l The

engine oil will deteriorate rapidly if the
vehicle is subjected to severe conditions, re-
quiring earlier oil replacement.
Please refer to the maintenance schedule.
l For information on how to dispose of used en-
gine oil, refer to page 05. Recommended engine oil viscosity
Petrol-powered vehicles
l
Select
engine oil of the proper SAE viscosity
number according to the atmospheric temper-
ature.
SAE 0W-20, 0W-30, 5W-30, and 5W-40 en-
gine oils can only be used if they meet
ACEA A3/B3, A3/B4 or A5/B5 and API SM
specifications.
l Use engine oil conforming to the following
classification:
• API classification: “For service SM”
• ILSAC certificated oil
• ACEA classification:“For service A1/B1, A3/B3, A3/B4 or
A5/B5”

Engine coolant
E01000501547
To check the coolant level
A
transparent coolant reserve tank (A) is located in
the engine compartment.
The coolant level in this tank should be kept be-
tween the “LOW” and “FULL” marks when meas-
ured while the engine is cold.
Petrol-powered vehicles
FULLLOW
Diesel-powered vehicles
FULL
LOW To add coolant
Petrol-powered vehicles
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 lid and add coolant.
Also, if the reserve tank is completely empty, re-
move the radiator cap (B) and add coolant until the
level reaches the filler neck. WARNING
l Do
not open the radiator cap (B) while
the engine is hot. The coolant system is un-
der pressure and any hot coolant escap-
ing could cause severe burns.

l Do
not open the reserve tank cap (C)
while the engine is hot. The coolant sys-
tem is under pressure and any hot cool-
ant escaping could cause severe burns. Anti-freeze
The

engine coolant contains an ethylene glycol anti-
corrosion agent. Some parts of the engine are cast
aluminium alloy, and periodic changing of the en-
gine coolant is necessary to prevent corrosion of
these parts.

Use “DIA QUEEN SUPER LONG LIFE COOL-
ANT PREMIUM” or equivalent*.
*: similar high quality ethylene glycol based non-
silicate, nonamine, 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, cylinder head, engine
block, 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. Maintenance
8-06

CAUTION
l
Concentrations exceeding 60 % will re-
sult in a reduction of both the anti-freeze
and cooling performance thus adversely
affecting the engine.
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 en-
gine or radiator could freeze and cause severe dam-
age to the engine 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. Washer fluid
E01000700832
Open

the washer fluid reservoir cap and check the
level of washer fluid with the dipstick.
If the level is low, replenish the container with wash-
er fluid.
EMPTY
FULL NOTE
l The

washer fluid container serves the wind-
screen, rear window and headlamps (if so
equipped).
During cold weather
To ensure proper operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Brake fluid/Clutch fluid*
E01000800631
The

brake fluid and the clutch fluid share the reser-
voir tank.
To check the fluid level
The fluid level must be between the “MAX” and
“MIN” marks on the reservoir. The fluid level is monitored by a float. When the
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 fluid in the master cylinder should be checked
when doing other work under the bonnet. The
brake system should also be checked for leakage at
the same time.
If the fluid level falls markedly in a short length of
time, it indicates leaks from the brake system.
If this occurs, we recommend you to have the vehi-
cle checked. Maintenance
8-07 8

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. Battery
E01001202131
The

condition of the battery is very important for
quick starting and to keep the vehicle’s electrical
system working properly. Regular inspection and
care are especially important in cold weather.
NOTE
l After replacing the battery, the electronic con-
trol system data for the automatic transmis-
sion, etc., will be erased. As a result, shift
shocks may occur.
Shift shocks will become smoother after sev-
eral changes in speed.
Checking battery electrolyte level The electrolyte level must be between the specified
limit

on the outside of the battery. Replenish with
distilled water as necessary.
The inside of the battery is divided into several com-
partments; 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 battery is not used, it will discharge by itself
with time.
Check it once every 4 weeks and charge with low
current as necessary.
Removing and installing the upper cov-
er and duct E01010700079
To replenish with the distilled water, remove the up-
per cover and duct. WARNING
l Turn
the ignition switch to the “LOCK”
position or put the operation mode in OFF.
Make sure that your clothes cannot be
caught by the fan or drive belt. Personal
injury could result. Maintenance

moulding (D). NOTE
l Attach

the moulding with the wide part to-
wards the front of the vehicle.
4. Install the clips (E). During cold weather
E01010900068
The capacity of the battery is reduced at low tem-
peratures.

This is an inevitable result of its chemi-
cal and physical properties.
This is why a very cold battery, particularly one
that is not fully charged, will only deliver a fraction
of the starter current which is normally available. Maintenance
8-09 8

We recommend you to have the battery checked be-
fore
the start of cold weather and, if necessary,
have it charged or replaced.
This does not only ensure reliable starting, but a bat-
tery which is kept fully charged also has a longer life.
Disconnection and connection E01011000079
To disconnect the battery cable, stop the engine,
first

disconnect the negative (-) terminal and then
the positive (+) terminal.
When connecting the battery, first connect the posi-
tive (+) terminal and then the negative (-) terminal.
NOTE
l Open the terminal cover (A) before discon-
necting or connecting the positive (+) termi-
nal of the battery.
l Loosen the nut (B), and then disconnect the
battery cable from the positive (+) terminal.
Petrol-powered vehicles
Diesel-powered vehicles WARNING
l Keep
sparks, cigarettes, and flames away
from the battery because the battery
could explode.
l The battery electrolyte is extremely caus-
tic. Do not allow it to come in contact
with your eyes, skin, clothing, or the pain-
ted 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 bat-
tery in an enclosed space. CAUTION
l
Keep it out of reach of children.
l Never

disconnect the battery with the ig-
nition switch or the operation mode in
ON. Doing so could damage electric com-
ponents. CAUTION
l
Never
short-circuit the battery. This
could cause it to overheat and be damaged.
l If the battery is to be quick-charged, first
disconnect the battery cables.
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 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.
NOTE l Keep

the terminals clean. After the battery is
connected, apply terminal protection grease.
To clean the terminals, use lukewarm water.
l Check to see if the battery is securely instal-
led and cannot be moved during travel. Also
check each terminal for tightness.
l When the vehicle is to be left unused for a
long period of time, remove the battery and
store it in a place where the battery fluid will
not freeze. The battery should be stored only
in a fully charged condition. Maintenance
