Service precautions
E01000100328
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 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 key to “LOCK” position and remove
the key to ensure safety while you work
in the engine compartment.
l Do not smoke, cause sparks or allow open
flames around fuel or battery. The fumes
are flammable. WARNING
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
E01000201007
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. CAUTION
l
Damage
to the catalytic converter can re-
sult if your vehicle is not kept in proper
operating condition. In the event of an en-
gine malfunction particularly involving
engine misfire or other apparent loss of
performance, have your vehicle serviced
promptly. Continued operation of your ve-
hicle with a severe overheated condition
may result in possible damage to the con-
verter and vehicle. 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. Maintenance

The catalytic converter itself gets hot quickly, and
may
be damaged if overheated. The following
points should be noted in order to prevent the igni-
tion of unburned petrol within the catalytic convert-
er.
l Use UNLEADED PETROL ONLY of the
type recommended in “Fuel selection” on
page 02.
l Do not drive with an extremely low fuel lev-
el; running out of fuel could cause damage to
the catalytic converter.
l Do not attempt to start the engine by pushing
the vehicle. If the battery is weak or dis-
charged, use another battery to start the en-
gine.
l Do not idle the engine with any spark plug
wires disconnected or removed such as per-
forming diagnostic tests.
l Do not idle the engine for prolonged periods
during very rough idle or malfunctioning op-
erating conditions.
l Do not race the engine when turning off the
ignition switch. This will cause the catalytic
converter to be damaged due to contact with
unburnt fuel.
l Stop driving the vehicle if you think the per-
formance is noticeably low, or if the engine
has a malfunction such as with the ignition,
etc.
If it is impractical to stop driving immediate-
ly, reduce the speed and drive for only a
short time. We recommend you to have your
vehicle inspected as soon as possible. l
In unusual situations involving grossly mal-
functioning engine operation, a burnt smell
may indicate severe and abnormal catalyst
overheating.
If this occurs, the vehicle should be stopped
in a safe place, the engine switched off and
the vehicle allowed to cool. Once the engine
is cool, a service, including a tune-up to man-
ufacturer’s specifications, should be obtained
immediately. Bonnet

NOTE
l Only
open the bonnet when the wipers are in
the parked position. Failure to do so may
cause bonnet damage.
Support the bonnet by inserting the support bar in
its slot. CAUTION
l
Note
that the support bar may disengage
the bonnet if the open bonnet is lifted by
a strong wind.
l Always insert the support bar into the
hole provided specifically for this pur-
pose. Supporting the bonnet at any other
location could result in the support bar
slipping out and lead to an accident.
To close
Unlatch the support bar and clip it in its holder. Slowly lower the bonnet to a position about 30 cm
above the closed position, then let it drop.
NOTE
l If

this does not close the bonnet, release it
from a slightly higher position.
l Do not press down the bonnet hard with a
hand as it may damage the bonnet. CAUTION
l
Be
careful that hands or fingers are not
trapped when closing the bonnet.
l Before driving, make sure that the bon-
net is securely locked. An incompletely
locked bonnet can suddenly open while
driving. This can be extremely dangerous. Engine oil

Diesel-powered vehicles (for
diesel particulate filter 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, and engine oil consumption is
greatly influenced by payload, engine speed, etc.
Therefore, it is important to check the oil level at
regular intervals or before starting a long trip.
This check must be made with the engine warm but
not running. Park the vehicle on a level surface,
stop the engine, and then wait a few moments to al-
low the engine oil in circulation to return to the oil
pan to ensure accurate measurement.
Remove the dipstick and wipe it with a clean cloth.
Reinsert the dipstick as far as it goes. Remove the
dipstick and read the oil level, which should al-
ways be within the range indicated.
If the oil level is below the specified limit, remove
the cap located on the cylinder head cover and add
enough oil to raise the level to within the specified
range.
Be sure to use the specified engine oil and do not
mix various types of oil. Also, avoid mixing differ-
ent makes of oil together if possible.
After adding oil, close the cap securely.
Use

only the recommended oils with an ACEA or
API classification as specified in this manual.
NOTE
l The engine oil will deteriorate rapidly if the
vehicle is subjected to severe conditions (for
example, repeated operation on rough roads,
in mountainous regions, on roads with many
uphill and downhill gradients, or over short
distances). Consequently, the oil will require
earlier replacement.
l For handling of used engine oils, refer to
page 06.
Selection of engine oil

Petrol-powered vehicles 1. Select
engine oil of the proper SAE viscosity
number according to the atmospheric temper-
ature.
SAE 0W-30, 5W-30, and 5W-40 engine oilscan only be used if they meet ACEA A3/B3,
A3/B4 or A5/B5 and API SG (or higher) spec-
ifications. 2. Use
engine oil conforming to the following
classification:
l API classification: “For service SG” or
higher
l ILSAC certificated oil
l 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.

Diesel-powered vehicles Use engine oil conforming to the following
classification:• Vehicles with DPF= “VW 50700”
• Vehicles without DPF= “VW50501/50601/50700”
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. Maintenance

Engine coolant
E01000501361
To check the coolant level
A
translucent coolant reserve tank is located in the
engine compartment.
Petrol-powered vehicles
Check the coolant level in the reserve tank. The re-
serve tank lid (B) is equipped with a dipstick.

Remove the dipstick and wipe it with a clean cloth.
Reinsert the dipstick as far as it goes. Remove the
dipstick and read the coolant level, which should al-
ways be within the range “F” (FULL) or “L”
(LOW) while the engine 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 “L” (LOW) level
on the dipstick, add coolant to the reserve tank. Also, if the reserve tank is completely empty, re-
move

the radiator cap (A) and add coolant until the
level reaches the filler neck. 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 severe 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 (minimum) °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.
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. Maintenance

Diesel-powered vehicles
The
coolant level in this tank should be kept be-
tween the “LOW” and “FULL” marks when meas-
ured while the engine 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 lid and add coolant. WARNING
l Do
not open the reserve tank cap while
the engine is hot. The coolant system is un-
der pressure and any hot coolant escap-
ing could cause severe 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 only “BASF Glysantin Alu Protect
Premium/G30”.
It has excellent protection against corrosion and
rust formation of all metals including aluminium
and can avoid blockages in the radiator, heater, cyl-
inder 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 anti-freeze must fill 50 % concentration cool-
ant in all temperature conditions. 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 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. Maintenance

Automatic transmission fluid*
E01000600857
The
proper amount of automatic transmission fluid
is essential to the life and operation of the automat-
ic transmission. Either insufficient fluid or exces-
sive fluid could cause transmission trouble. The
transmission fluid filler port cap is equipped with a
dipstick. Use the following procedure to check the
fluid level.
Procedure for checking the fluid level
1. Check the fluid level after the vehicle hasbeen driven enough to warm up the transmis-
sion fluid.
2. Park the vehicle on a flat, level surface and apply the parking brake.
3. With the engine idling and the brake pedal fully depressed, move the transmission selec-
tor lever through all the positions from P”
(PARK) to “D” (DRIVE), stopping momen-
tarily at each position.
4. Move the selector lever to the “P” (PARK) position.
5. Remove the dipstick and wipe it with a clean lint-free cloth.
6. Reinsert the dipstick as far as it goes. 7. Remove dipstick and read the oil level.
The fluid level should always be between the
two marks on the dipstick. WARNING
l Do
not spill the fluid onto a hot exhaust
manifold during topping up or inspec-
tion, or a fire may occur.
Fluid type
Use
only “DIA QUEEN ATF SP III” transmission
fluid to ensure optimum transmission performance. Washer fluid
E01000700164
Check

the float (A) is between the “FULL” and
“EMPTY” marks on the washer fluid reservoir.
If the level is low, replenish the container with wash-
er fluid. NOTE
l The

washer fluid container serves the wind-
screen, rear window and headlamps*.
During cold weather
To ensure proper operation of the washers at low
temperatures, use a fluid containing an anti-freez-
ing agent. Maintenance
