CAUTION
• When washing around the door glass,
hold the nozzle at a distance of more
than 70 cm and at right angles to the
glass surface.
l After washing the vehicle, drive the vehi-
cle slowly while lightly depressing the
brake pedal several times in order to dry
out the brakes.
Leaving the brakes wet could result in re-
duced braking performance. Also, there
is a possibility that they could freeze up
or become inoperative due to rust, render-
ing the vehicle unable to move.
l When using an automatic car wash, pay
attention to the following items, referring
to the operation manual or consulting a
car wash operator. If the following proce-
dure is not followed, it could result in dam-
age to your vehicle.
• The outside mirrors are retracted.
• The antenna is removed.
• The wiper arms are secured in placewith tape.
• If your vehicle is equipped with a rear spoiler or roof rails, consult a car
wash operator before using the car
wash.
• If your vehicle has rain sensor wipers, place the wiper switch lever in the
“OFF” position to deactivate the rain
sensor. During cold weather
Salt

and other chemicals spread on the roads in
some areas in winter can have a harmful effect on
the vehicle body. You should therefore wash the ve-
hicle as often as possible in accordance with our
care-instructions. It is recommended to have a pres-
ervative applied and the underfloor protection
checked before and after the cold weather season.
After washing your vehicle, wipe off all water-
drops from the rubber parts around the doors to pre-
vent the doors from freezing.
NOTE
l To prevent freezing of the weatherstripping
on the doors, bonnet, etc., they should be trea-
ted with silicone spray.
Waxing E00901000863
Waxing the vehicle will help prevent the adherence
of

dust and road chemicals to the paintwork. Apply
a wax solution after washing the vehicle, or at least
once every three months to assist displacing of water.
Do not wax your vehicle in direct sunlight. You
should wax after the surfaces have cooled. CAUTION
l
Waxes
containing high abrasive com-
pounds should not be used. Such waxes re-
move rust and stains effectively from the
paintwork but they are harmful to the lus-
tre on the painted surface and the plated
surface.
Further, they are harmful to glossy surfa-
ces such as grille, garnish, mouldings, etc. CAUTION
l
Do
not use petrol or paint thinners to re-
move road tar or other contamination to
the painted surface.
l Do not apply wax to sections that have a
black mat paint coating, as doing so
could cause uneven discolouration, spots
or stains. If wax gets on such areas, wipe
it off using lukewarm water and a soft
cloth.
Polishing E00901100066
The vehicle should only be polished if the paint-
work

has become stained or lost its lustre. Do not
polish parts with a mat coating and the plastic bump-
ers. Doing so could cause stains or damage the finish.
Damaged paint E00901200054
Small cracks and scratches in the paint coat should
be

touched up as soon as possible with
MITSUBISHI touch-up paint to prevent corrosion.
Check body areas facing the road or the tyres care-
fully for damage to the paint caused by gravels,
etc. The paint code number for your vehicle can be
found on the vehicle information code plate in the
engine compartment.
Cleaning plastic parts E00901300707
Use a sponge or chamois leather.
If

a car wax adheres on a grey or black rough sur-
face of the bumper, moulding or lamps, the surface
becomes white. In such a case, wipe it off using
lukewarm water and soft cloth or chamois leather. Vehicle care

Service precautions
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

MAX. MIN. Diesel-powered vehicles
MAX. MIN.
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

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. Engine coolant
E01000501736
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.
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.
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.
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, 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, 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 Maintenance
8-06

OGWE12E1

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 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

OGWE12E1

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

Fuel, engine coolant, oil and exhaust
gas leakage
Look
under the body of your vehicle to check for
fuel, engine coolant, oil and exhaust gas leaks. WARNING
l If
you see a suspicious fuel leak or if you
smell fuel, do not operate the vehicle; call
your MITSUBISHI MOTORS Author-
ized Service Point for assistance.
Exterior and interior lamp operation
Operate
the combination lamp switch to check that
all lamps are functioning properly.
If the lamps do not illuminate, the probable cause
is a blown fuse or defective lamp bulb. Check the
fuses first. If there is no blown fuse, check the
lamp bulbs.
For information regarding the inspection and re-
placement of the fuses and the lamp bulbs, refer to
“Fuses” on page 8-18 and “Replacement of lamp
bulbs” on page 8-24.
If the fuses and bulbs are all OK, we recommend
you to have your vehicle checked and repaired.
Meter, gauge and indicator/warning
lamps operation
Start the engine and check the operation of all in-
struments, gauges and indication and warning lamps.
If there is anything wrong, we recommend you to
have your vehicle inspected. Hinges and latches lubrication
Check

all latches and hinges, and, if necessary,
have them lubricated. For cold and snowy weather
E01002800361
Ventilation slots
The
ventilation slots in front of the windscreen
should be kept clear of leaves or brushed clear after
heavy snowfall, so that the operation of the heating
and ventilation systems will not be impaired.
Weatherstripping
To prevent freezing of the weatherstripping on the
doors, bonnet, etc., they should be treated with sili-
cone grease.
Additional equipment
It is a good idea to carry a shovel or a short-han-
dled spade in the vehicle during the winter so that
you can clear away snow if you get stranded. A
small hand-brush for sweeping snow off the vehi-
cle and a plastic scraper for the windscreen and
rear window are also useful. Maintenance

corresponding to that system is normal, there
may be a fault in the system elsewhere. We
recommend you to have your vehicle checked.
4. Use the fuse puller to insert a new fuse with the same capacity. Make sure you insert the
fuse into the same location in the fuse block. CAUTION
l
If
the newly inserted fuse blows again af-
ter a short time, we recommend you to
have the electrical system checked to find
the cause and rectify it.
l Never use a fuse with a larger capacity
than specified or a substitute (such as a ca-
ble or foil). Doing so could cause the cir-
cuit wires to overheat and create a fire. Maintenance
