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
N00940900198
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.Ignition cables
N00941100041
The ignition cables should be kept clean, properly connected,
and fully seated. Terminals should be fully seated and the nip-
ple assemblies should not be removed from the coil towers
unless the nipples are damaged or cable testing indicates high
resistance or broken insulation. Cracked or damaged cables
must be replaced.Intake valve clearance
N00950100050
Have the valve clearance checked at an authorized Mitsubishi
Motors dealer at the mileage specified in the “WARRANTY
AND MAINTENANCE MANUAL”.
If the engine sounds abnormally loud, have adjustments made
by an authorized Mitsubishi Motors dealer.
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.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”.
WARNING
!
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.

Drive belt (for generator, power steering pump,
air conditioning compressor)
N00941900267
Check 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.Except for vehicles with turbocharger
WARNING
!
Do not check or touch the drive belt with the engine
running, or serious injury or death may result.Vehicles with turbocharger

7For cold and snowy weather
N00942600102
Ventilation slotsThe ventilation slots in front of the windshield should be
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.
Fusible links
N00942700259
The fusible links will melt to prevent a fire if a large current
attempts to flow through certain electrical systems.
In case of a melted fusible link, see your authorized Mitsubishi
Motors dealer or a repair facility of your choice for inspection
and replacement.
For the fusible links, please refer to “Fuse load capacities” on
page 7-49.
WARNING
!
Fusible links must not be replaced by any other
device. Failing to fit the correct fusible link may
result in fire in the vehicle, property destruction and
serious or fatal injuries at any time.

2. For vehicles with the bottom cover, use the puller to
loosen the 2 clips (A) and push down the bottom cover.
The puller is in the fuse block in the engine compartment.
Refer to “Fuse replacement” on page 7-54.NOTE
When finished, be sure to return the puller to the fuse
block in the engine compartment.3. To put back the fuse lid, line up the fuse lid hook (B) with
the clamp (C) on the instrument panel and push the lid
back in.
WARNING
!
When changing fuses, do not damage the driver’s
knee airbag harness or accidentally strike the airbag
area with hard objects. Improper work methods
could result in an accidental driver’s knee airbag
deployment or could make the driver’s knee airbag
inoperable. Either of these situations could result in
serious injury or death.

*- Fusible link

Some fuses may not be installed on your vehicle, depend-
ing on the vehicle model or specifications.

The table above shows the main equipment corresponding
to each fuse.There are no 7.5 A, 25 A or 30 A spare fuses. If a fuse of one of
these capacities blows, replace it temporarily by borrowing one
of the fuses indicated below.
7.5 A: 10 A spare fuse
25 A: 20 A spare fuse
30 A: 30 A audio amplifier fuse
Replace the borrowed fuse with a fuse that has the correct
capacity as soon as possible.

4. Use the fuse location diagrams and the matching tables, to
check the fuse that is related to the problem. If the fuse is
not blown, something else must be causing the problem.
Contact an authorized Mitsubishi Motors dealer or a
repair facility of your choice to have the problem checked.5. Insert a new fuse of the same capacity securely into the
appropriate slot. B- Fuse is OK
C- Blown fuse
CAUTION
!
Never use a fuse with a capacity greater than the one
listed or any substitute, such as wire, foil etc. This
would cause the circuit wiring to heat up and could
cause a fire.
If the replacement fuse blows again after a short
time, have the electrical system checked by an
authorized Mitsubishi Motors dealer or a repair
facility of your choice to find and correct the cause.
