7 Emission-control system maintenance
N00940800201
Your vehicle is equipped with an emission-control system that
meets all the requirements of the U.S. Environmental Protec-
tion Agency and Environment Canada. The emission-control
system is made of:

a positive crankcase ventilation system

an evaporative emission-control system

an exhaust emission-control system
The maintenance services listed in the “WARRANTY AND
MAINTENANCE MANUAL” must be performed at the times
or mileages listed to keep the emission-control system working
properly. These, and all the other “general” maintenance ser-
vices listed in this manual, need to be performed to keep your
vehicle running properly and reliably.
You may need more frequent maintenance if you drive your
vehicle in harsh conditions such as dusty areas or do a lot of
start-and-stop driving.
To be sure the emission-control system works properly, have
your vehicle inspected and maintained by an authorized Mit-
subishi Motors dealer or a repair facility of your choice follow-
ing the schedule in the “WARRANTY AND MAINTENANCE
MANUAL”.
You should also have an inspection and service any time you
suspect a malfunction.
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
N00940900257
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”. 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.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)
N00941300186
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”.
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
N00941600075
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.
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.

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-
age

Bellows on both ends of the drive shaft
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
!
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
N00942500114
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.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.

During cold weather Salt and other chemicals spread on winter roads in some geo-
graphical areas can have a detrimental effect on the vehicle
underbody. You should flush the underbody with a high pres-
sure hose every time you wash the outside of your vehicle.
Take special care to remove mud or other debris which could
trap and hold salt and moisture.
After washing your vehicle, wipe off all waterdrops from the
rubber parts around the doors to prevent the doors from freez-
ing.
CAUTION
!
When washing the underside of your vehicle or the
wheels, wear a pair of gloves to protect your hands.
If your vehicle has rain sensor wipers, place the
wiper switch lever in the “OFF” position to deacti-
vate the rain sensor before washing the vehicle. Oth-
erwise, the wipers will operate in the presence of
water spray on the windshield and may get damaged
as a result.
Never spray or splash water on the electrical parts
in the engine compartment. This may damage them.
Be careful also when washing the underbody. Do not
spray water into the engine compartment.
Avoid automatic car washers that use rotating
brushes. These brushes may scratch the paint sur-
face and make it dull.
Scratches are more noticeable on darker colored
vehicles.
Some hot water washing equipment uses high pres-
sure and heat to clean your vehicle. This heated
water may damage your vehicle’s resin parts. It can
flood the interior of the vehicle. Therefore, be sure
of the following:
• Keep the washing nozzle at least 20 inches (50 cm)
away from the vehicle body.
• When washing around the door glass, hold the
nozzle at a distance of more than 20 inches (50 cm)
and at right angles to the glass surface.

When using high-pressure water to wash a vehicle
equipped with the F.A.S.T.-key system, keep the
water from spraying on the open button on the rear
hatch. This could cause the rear hatch to open and
flood the inside of the rear hatch.
Make sure to do the following when using an auto-
matic car wash, with help from either this manual or
the car wash operator, to avoid damaging your vehi-
cle:
• Fold the outside rear-view mirrors.
• Put down (except for vehicles equipped with SIR-
IUS satellite radio antenna only) or remove the
antenna.
• If your vehicle is equipped with rear spoiler, check
with the 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 deacti-
vate the rain sensor.CAUTION

NOTE
When the door is frozen, opening it by force may tear off
or crack the rubber gasket installed around the door. Pour
warm water to melt the ice. Be sure to thoroughly wipe off
the water after opening the door. To prevent freezing of
the weatherstripping on the doors, hood, etc., treat with
silicone lubricant.Waxi n g
N00946000218
Wax your vehicle once or twice a year, or when water does not
bead up on the paint.
Use a soft cloth to put a small amount of wax on the painted
surfaces. After the wax has dried, polish with a dry soft cloth.
Do not wax your vehicle in direct sunlight.
You should wax when the painted surfaces are cool.
Polishing
N00946100059
If painted surfaces have been severely damaged and lost their
original luster and color tone, polish the surface lightly with a
fine polishing compound. Avoid limiting your polishing to the
damaged surface only; polish a somewhat wider area, moving
the polishing cloth in one direction. After polishing, flush the
compound from the surface and apply a coat of wax to regain a
beautiful luster.Damaged paint
N00946200063
Small cracks and scratches in the paint coat should be touched
up as soon as possible with touch-up paint to prevent corrosion.
Check body areas facing the road or the tires carefully for dam-
age to the paint caused by flying stones, etc. The paint code
number for your vehicle can be found on the vehicle informa-
tion code plate in the engine compartment.
CAUTION
!
Waxes containing high abrasive compounds should
not be used. These waxes remove rust and stain
effectively from the paintwork, but are harmful to
the finish on the paint and the plate, because they
also remove clearcoat.
They are also harmful to other glossy surfaces such
as the grille, trim, moldings, etc.
Do not use gasoline, kerosene, benzine or paint thin-
ners to remove road tar or other dirt from the vehi-
cle surface.

Do not put wax on the areas having black matte
coating because it can cause uneven discoloration,
patches, blurs, etc. If these get wax on them, wipe
the wax off right away with a soft cloth and warm
water.
On vehicles equipped with sunroof, be careful not to
apply any wax on the weatherstrip (black rubber)
when waxing the area around the sunroof opening.
If stained with wax, the weatherstrip cannot main-
tain a weatherproof seal with the sunroof.
