and emission-control.
Do not reuse them by cleaning or regapping. Change them at
the mileage listed in the “WARRANTY AND MAINTE-
NANCE MANUAL”.

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 9-7 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.

7General 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
N00941600062
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.
Ball joint, steering linkage seals and drive shaft
boots
N00941800077
Check the following parts for damage and grease leaks:

Ball joint boots of the front suspension and steering link-

Drive belt (for generator, power steering pump,
air conditioning compressor)
N00941900225
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.
Exhaust system
N00942200108
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 luggage compartment and passenger compart-
ments.
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.
WA R N I N G
!

Do not check or touch the drive belt with the engine
running, or serious injury or death may result.
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.

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.
For 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.We a t h e r s t r i p p i n gTo 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.

and replacement.
For the fusible links, please refer to “Fuse load capacities” on
page 7-37.
