Your vehicle is equi
pped with an emission-
control system that meets all the requirementsof the U.S. Environm
ental Protection Agency
and Environment Cana
da. The emission-con-
trol system is made of:a positive crankcase
ventilation system
an evaporative emis
sion-control system
an exhaust emission-control system
To be sure the emissi
on-control system works
properly, have your vehicle inspected andmaintained by an authorized MitsubishiMotors dealer or a repair facility of yourchoice. This should be done at the time ormileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”.These, and all the other “general” mainte-nance services listed in this manual, need tobe performed to keep
your vehicle running
properly and reliably.You should also have an inspection and ser-vice any time you suspect a malfunction.

Spark plugs must fire properly to ensureproper engine perfo
rmance and emission-
control.Do not reuse spark plugs by cleaning orregapping. Spark plugs should be replaced atthe mileage specified in the “WARRANTYAND MAINTENANCE MANUAL”.
Check the hose surfaces for any heat andmechanical damage, hard and brittle rubber,cracking, tears, cuts and abrasions. Pay spe-cial attention to the hos
es closest to high heat
sources such as the exhaust manifold. Checkall 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 ordamage, replace the
hoses immediately.

Check these regularly for damage or leaks inthe fuel lines and connections. Check the fueltank filler cap for dama
ge or looseness. Pay
special attention to the fuel lines closest to
Emission-control system maintenance
NOTE
To meet government regulations and pro-mote cleaner air, your
vehicle is equipped
with an onboard dia
gnostic system (OBD).
The engine electronic control module thatcontrols OBD functions stores various data(especially a
bout the exhaust emissions).
This data will be erased if the battery cable isdisconnected, which c
ould make a rapid
diagnosis difficult.
Do not disconnect the
battery cable when the engine malfunctionindicator (“SERVICE ENGINE SOON” or“Check engine
light”) is ON.
Spark plugs
NOTE
Use the recommended or equivalent sparkplugs listed under “Engin
e specifications” on
page 11-6. Use of other plugs could causeengine damage, loss of performance or radionoise.

The best way to keep carbon monoxide gasfrom entering inside your
vehicle is to have
the engine exhaust syst
em properly serviced.
Have a competent mechanic inspect the com-plete exhaust system
and nearby body areas
for broken, damaged, deteriorated, or mispo-sitioned parts if you no
tice any of the follow-
ing:A change in the sound of the exhaust sys-temThe smell of exhaust fumes inside thevehicle
WA R N I N GIf you see a fuel leak
or if you smell fuel,
do not run the engine. Any spark (includ-ing from the ignition
), flame or smoking
material could cause an explosion or fire.Call an authorized
Mitsubishi Motors
dealer or a repair fa
cility of your choice
for assistance.

The hood lock release mechanism and hoodsafety catch should be checked, cleaned, andoiled when needed for easy movement and toprevent rust and wear. Use MultipurposeGrease NLGI Grade 2 sparingly for all slidingparts of the hood latch and release lever.Work the grease into the hood lock mecha-nism until all the movable surfaces are cov-ered.Also, put a light coat
of the same grease on
the safety catch wherever moving parts touch.
N00942600102
The ventilation slots in
front of the wind-
shield should be brushed clear after a heavysnowfall so that the operation of the heatingand ventilation systems will not be impaired.
To prevent freezing of the weatherstrippingon the doors, engine hood, etc., they shouldbe treated with
silicone grease.
It is a good idea to carry a shovel or a short-handled spade in the vehicle during the win-ter so that you can clear away snow if you getstranded. A small hand-brush for sweepingsnow off the vehicle a
nd a plastic scraper for
the windshield, side a
nd rear window are also
useful.

Wax your vehicle once or twice a year, orwhen water does not bead up on the paint.Use a soft cloth to put a small amount of waxon 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 surfacesare cool.
Never spray or splash water on the electricalparts in the engine compartment. This maydamage them. Be careful also when washingthe underbody to ensure that water does notenter the engine compartment.Avoid automatic car washers that use rotat-ing brushes. These br
ushes may scratch the
paint surface a
nd make it dull.
Scratches are more not
iceable on darker col-
ored vehicles.Some hot water wash
ing equipment uses
high pressure and heat
to clean your vehicle.
Because hot water can da
mage plastics parts
and seep inside your ve
hicle, make sure you
do the following when using such equip-ment:• Keep the washing nozzle at least 28 inches(70 cm) away from the vehicle body.• When washing around the door glass, holdthe nozzle at a distance of more than 28inches (70 cm) and at a right angle to theglass surface.
Make sure to do the following when using anautomatic car wash, with help from eitherthis manual or the car wash operator, toavoid damaging your vehicle:• Fold the outside
rearview mirrors.
• Tape or remove the rear wiper arm assem-bly.• If your vehicle is equi
pped with a roof rails,
check with the car wash operator beforeusing the car wash.CAUTION
• If your vehicle is e
quipped with the rain
sensor, place th
e wiper switch lever in the
“OFF” position to deac
tivate the rain sen-
sor.
During cold weather
NOTE
When the door is frozen, opening it by forcemay tear off or crack the rubber gasketinstalled around the door. Pour warm waterto melt the ice. Be
sure to thoroughly wipe
off the water after opening the door. To pre-vent freezing of the
weatherstripping on the
doors, hood, etc., treat
with silicone lubri-
cant.CAUTION
Waxing
CAUTIONWaxes containing high abrasive compoundsshould not be used. Th
ese waxes remove rust
and stain effectively fr
om the paintwork, but
are harmful to the finish of the paint, becausethey also remove
paint/clearcoat.
They are also harmful to other glossy sur-faces such as the grille, trim, moldings, etc.Do not use gasoline, benzine, kerosene orpaint thinners to remove
road tar or other dirt
from the vehicle surface.Do not put wax on the areas having blackmatte coating because
it can cause uneven
discoloration, patches, bl
urs, etc. If these get
wax on them, wipe the wax off right awaywith a soft clot
h and warm water.
