Service precautions
E01000100764
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 other problem
is discovered, we recommend you to have it
checked and repaired. This section contains infor-
mation on inspection maintenance procedures that
you can do yourself.
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 fans,
drive belts, or other moving parts.
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. WARNING
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
E01000201355
For ordinary use,

there are no particular precau-
tions except that of using unleaded petrol.
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 In
case of

the petrol-powered vehicles, use
UNLEADED PETROL ONLY of the type
recommended in “Fuel selection” on page 02. Maintenance

3800 models 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.
8. After adding oil, close the cap securely.
9. Confirm the oil level by repeating step 4 to 6. Maintenance

Use only the recommended oils with an ACEA or
API classification as specified in this manual.
NOTE
l For
3200 models,
check or refill the oil ac-
cording to the following manner. • When the oil level is checked in step 6above, check it on a low side of the dip-
stick because it is different in appearance
of oil level in the two sides of the dipstick.
• On vehicles without diesel particulate fil- ter (DPF), the oil level should be within
the range (A) to (B) on the dipstick.
• On vehicles with DPF, the oil level should be within the range (A) to (C) (oil
replacement indication mark) on the dip-
stick.
If the oil level is beyond the oil replace-
ment indication mark (C), replace the oil
as soon as possible.
Then, the oil should be refilled to the max-
imum level (B).
• On vehicles with DPF, the engine oil will increase due to a little fuel getting mixed
in the engine oil when the DPF regener-
ates to burn away the PM (particulate mat-
ter). However, it does not indicate a mal-
function.
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 handling of used engine oils, refer to
page 06. Selection of engine oil
Petrol-powered vehicles
l
Select engine
oil
of the proper SAE viscosity
number according to the atmospheric temper-
ature.
SAE 0W-30, 5W-30, and 5W-40 engine oils
can only be used if they meet ACEA A3/B3,
A3/B4 or A5/B5 and API SM (or higher) spec-
ifications.
l Use engine oil conforming to the following
classification:
• API classification: “For service SM” orhigher
• ILSAC certificated oil
• ACEA classification: “For service A1/B1, A3/B3, A3/B4 or
A5/B5” NOTE
l Use
of additives

is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical assem-
bly.

E01000501273
To check the coolant level
A translucent
coolant
reserve tank 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. 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 lid and add coolant.
Also, if the reserve tank is completely empty, re-
move the radiator cap and add coolant until the lev-
el reaches the filler neck. Maintenance

OBKE12E1

WARNING
l Do not open the radiator cap while the en-
gine is hot.
The coolant system is under pressure and
any hot coolant escaping could cause se-
vere burns.
Anti-freeze
The engine coolant

contains an ethylene glycol anti-
corrosion agent. The cylinder head and water pump
housing are cast aluminium alloy, and periodic
changing of the engine coolant is necessary to pre-
vent corrosion of these parts.

Use “DIA QUEEN SUPER LONG LIFE COOL-
ANT” or equivalent.
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. Ambient
temperature (mini-
mum) °C -15 -20 -25 -30 -35 -50 Anti-freeze
concentra- tion % 30 35 40 45 50 60 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 For effective anti-corrosion and anti-
freeze performance, keep the anti-freeze
concentration within the range of 30 to
60 %.
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.
During cold weather
The concentration should

be checked before the
start of cold weather and anti-freeze added to the
system if necessary to prevent damage to engine
and radiator due to freezing. Washer fluid
E01000700656
Windscreen washer fluid
The windscreen washer

fluid reservoir is in the en-
gine compartment.
Check the washer fluid level at regular intervals
and add washer fluid to reservoir if necessary. NOTE
l The
washer fluid

container serves the wind-
screen and headlamps (if so equipped). Maintenance

1. Remove the rear
window washer fluid reser-
voir filler port lid (A) on the backdoor. 2. Pull out the rear window washer fluid reser-
voir filler

port (B) and check the washer flu-
id level.
If the level is low, replenish the container
with washer fluid. During cold weather
E01006600019
To ensure proper

operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Brake fluid
E01000900847
To check the fluid level
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 brake fluid level must be between the “MAX”
and “MIN” marks on the reservoir.

OBKE12E1

1. Turn the ignition switch to the “LOCK” or
“ACC” position.
2. Repeatedly
depress the brake pedal until sig-
nificant resistance is felt (normally after
about 40 times).
3. Check the brake fluid level in the reservoir. The brake fluid level must be between the
“MAX” and “MIN” marks on the reservoir.
The fluid level falls slightly with wear of the brake
pads, but this does not indicate any abnormality.
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
brake performance. 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. CAUTION
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. Clutch fluid*
E01001000193
To check the fluid level
The clutch fluid

in the master cylinder should be
checked when performing other underhood service.
In addition, the system should be checked for leak-
age at the same time.
Check to ensure that the clutch fluid level is always
between the “MAX” and “MIN” level markings on
the fluid reservoir.
