NOTE
To meet government regulations and promote cleaner air,
your vehicle is equipped with an onboard diagnostic sys-
tem (OBD). The engine electronic control module that
controls OBD functions stores various data (especially
about the exhaust emissions). This data will be erased if
the battery cable is disconnected, which could make a
rapid diagnosis difficult. Do not disconnect the battery
cable when the engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is on.Spark plugs
N00940900039
Spark plugs must fire properly for good engine performance
and emission-control.
Do not reuse them by cleaning or regapping. Change them at
the mileage listed in the “WARRANTY AND MAINTE-
NANCE MANUAL”.
Your vehicle may be equipped with iridium tipped spark plugs,
which are identified by marks on the ceramic. They do not
require replacement as frequently as the conventional type
spare plug and will last much longer.NOTE
Use the spark plugs listed under “Engine specifications”
on page 9-8 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.
Fuel hoses
N00941000037
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Pay
special attention to the hoses closest to high heat sources such
as the exhaust manifold. Check all the hose connections, such
as clamps and couplings, to make sure they are secure and that
there are no leaks. If you see any wear or damage, replace the
hoses immediately.Fuel system (tank, pipe line and connection, and
fuel tank filler cap)
N00941300085
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler cap for damage or loose-
ness. Pay special attention to the fuel lines closest to high heat
sources such as the exhaust manifold.
WA R N I N G
!
If you see a fuel leak or if you smell fuel, do not run
the engine. Any spark (including from the ignition),
flame or smoking material could cause an explosion
or fire. Call an authorized Mitsubishi Motors dealer
or a repair facility of your choice for assistance.

Evaporative emission control system (except
evaporative emission canister)
N00941400116
If the fuel-vapor vent line is clogged or damaged, the fuel-
vapor mixture will escape, polluting the air.
Have the system checked at an authorized Mitsubishi Motors
dealer at the mileage specified in the “WARRANTY AND
MAINTENANCE MANUAL”.
General maintenance
N00941500159
The next pages list the maintenance service recommended by
Mitsubishi Motors Corporation. In addition to the general
maintenance that needs to be performed at the times listed,
there are other parts which do not usually need regular mainte-
nance.
But, if any of these parts stops working properly, your vehicle
performance could suffer. Have these items checked if you
notice a problem with them.
See your authorized Mitsubishi Motors dealer for assistance, if
you have any questions.Disc brake pads
N00941600020
Good brakes are essential to safe driving. Check the brake pads
for wear. For good braking performance, replace the brake pads
with the same type pads as the originals.Brake hoses
N00941700047
Brake hoses and tubing should be checked for:

Severe surface cracking, scuffing or worn spots. If the
fabric casing of the hose is showing through any cracks or
worn spots in the rubber hose cover, the hose should be
replaced. The brakes can fail if the hose wears through.

Improper installation may cause twisting, or wheel, tire or
chassis interference.

air conditioning compressor)
N00941900124
2.4 liter modelsCheck the tension of the drive belt. Make certain that the indi-
cator (A) is between the specified lines as shown in the illustra-
tion.
Check the drive belt for cuts and cracks, and replace it if it is
damaged. When replacing the belt, make sure that there is no
interference between the belt and other engine components.
After replacing, recheck the tension to make sure the indicator
(A) is between the specified lines.

3.8 liter modelsCheck the tension of the drive belt. The deflection must be
within specifications, when pressed at a point halfway between
the pulleys as shown in the illustration with a force of about 22
pounds (100N).
Check the drive belt for cuts and cracks, and replace it if it is
damaged.
When replacing the belt with a new belt, make sure that there is
no interference between the belt and other engine components.
Then, check the tension of the belt at the designated point. The
deflection must be within the specifications.

Exhaust system
N00942200078
The best way to keep carbon monoxide gas from entering
inside your vehicle is to have the engine exhaust system prop-
erly serviced.
Have a competent mechanic inspect the complete exhaust sys-
tem and nearby body areas for broken, damaged, deteriorated,
or mispositioned parts if you notice any of the following:

A change in the sound of the exhaust system

The smell of exhaust fumes inside the vehicle

The underside or rear of the vehicle is damaged
Also check the exhaust system each time the vehicle is raised
for lubrication, oil changes, or required service. Any open
seams or loose connections could let dangerous exhaust fumes
seep into the cargo area and passenger compartments. Check for any of the following conditions:
Check for holes or exhaust gas leaks caused by corrosion
or damage.

Check the joints and connections for looseness or exhaust
gas leaks.

Check the rubber hangers and brackets for damage.
Timing belt
N00942300053
The timing belt should be replaced with a new one at the mile-
age listed in the “WARRANTY AND MAINTENANCE
MANUAL”.Hood lock release mechanism and safety catch
N00942500042
The hood lock release mechanism and hood safety catch should
be checked, cleaned, and oiled when needed for easy move-
ment and to stop rust and wear. Use Multipurpose Grease
NLGI Grade 2 sparingly for all sliding parts of the hood latch
and release lever. Work the grease into the hood lock mecha-
nism until all the movable surfaces are covered.
Also, put a light coat of the same grease on the safety catch
wherever moving parts touch.
WA R N I N G
!
Carbon monoxide gas from your vehicle’s exhaust is
poisonous. Breathing these fumes can cause uncon-
sciousness or death.

N00942600115
Ventilation slotsThe ventilation slots in front of the windshield should be kept
clear of leaves or brushed clear after a heavy snowfall, so that
the operation of the heating and ventilation systems will not be
impaired.WeatherstrippingTo prevent freezing of the weatherstripping on the doors,
engine hood, etc., they should be treated with silicone grease.Additional equipment (For regions where snow is
encountered)It is a good idea to carry a shovel or a short-handled 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 vehicle and a plastic scraper for the windshield, side and
rear window are also useful.
Fuse links
N00942700099
The fuse links will melt to prevent a fire if a large current
attempts to flow through certain electrical systems.
In case of a melted fuse link, see your authorized Mitsubishi
Motors dealer or a repair facility of your choice for inspection
and replacement.
