NOTE
Check each battery terminal for corrosion. You can stop
more corrosion by washing with a solution of baking soda
and water. Grease the posts and clamps after cleaning or
tightening them.

Check to see that the battery is securely installed and can-
not be moved. Also check each terminal for tightness.

If you will not be driving your vehicle for a long period of
time, remove the battery and store it in a place where the
battery fluid will not freeze. Memory data for settings
made by the user may be erased when the battery is
removed. If this happens, reset the settings again using the
relevant procedures. The battery only should be stored
with a full charge.

Before cleaning the battery, tighten all the filler port caps
to keep dirt and moisture out.
WA R N I N G
!
Never disconnect the battery while the engine is run-
ning, or you could damage the vehicle’s electrical
parts.
Never short-circuit the battery. This could cause it
to overheat and be damaged.
Keep sparks, cigarettes, and flames away from the
battery because the battery could explode.
Electrolyte (battery acid) is made of corrosive
diluted sulfuric acid. If it spills on nearby parts, it
can crack, stain, or discolor them. And if gets on
your skin or in your eyes, it can cause burns or
blindness. Please observe the following handling
instructions:
• If electrolyte gets on plastic parts or other nearby
parts, wipe it off with a soft cloth or chamois
soaked in a solution of water and neutral detergent
then immediately rinse the affected parts with
plenty of water.
• If electrolyte gets on your hands or clothes, rinse
thoroughly with water. If electrolyte gets in your
eyes, flush them with water immediately and get
immediate medical attention.

Open doors and windows in any closed space where
you may be charging or working with the battery.
Always wear protective clothing and goggles when
working with the battery, or have a skilled automo-
bile technician do it.
If you are quick-charging your battery, first discon-
nect the battery cables.

In order to prevent a short circuit, be sure to discon-
nect the negative (-) terminal first, and reconnect it
last.
If the electrolyte level is very low, have the battery
checked at an authorized Mitsubishi Motors dealer
or a repair facility of your choice.
Battery terminals and related accessories contain
lead and lead compounds. Wash hands after han-
dling.

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
N00940900215
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

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.

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.
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.
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.

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.
Cleaning plastic parts
N00946300178
Use a sponge or chamois to clean these parts.
If a vehicle wax sticks to a gray or black rough surface of the
bumper, molding or lights, the surface may appear white in
color. In this case, wipe it off using lukewarm water and a soft
cloth or chamois. Chrome parts
N00946400065
To prevent spots and corrosion of chrome parts, wash with
water, dry thoroughly, and apply a nonabrasive automotive
wax. If the chrome is severely damaged or pitted, use a com-
mercially available chrome polish.

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 with sunroof, be careful not to apply any
wax on the weatherstrip (black rubber) when wax-
ing the area around the sunroof opening.
If stained with wax, the weatherstrip cannot main-
tain a weatherproof seal with the sunroof.
CAUTION
!
CAUTION
!
Do not use a scrubbing brush or other rough scrub-
ber as these may damage the plastic surface.
Do not use wax containing compounds (polishing
powder) which may damage the plastic surface.
Do not let the plastic parts get soiled with gasoline,
oil, brake fluids, engine oils, greases, paint thinner,
and sulfuric acid (battery electrolyte). These fluids,
etc., may crack, stain or discolor the plastic parts.
If any of these get on the plastic parts, wipe them up
with a soft cloth or chamois and a mild solution of
soap and water. Then rinse them immediately with
water.
