To check the battery indicator
N00901400042
To see the charge of only one cell, check the indicator (A) on
top of the battery. If the indicator is blue when looking from
above, that cell is okay suggesting the battery is okay. This is
not conclusive and if battery performance is suspect, have the
battery and charging system tested by an authorized Mitsubishi
Motors dealer or a repair facility of your choice. If it is white,
that cell is low on charge and the battery may only need charg-
ing.
CAUTION
!

Be sure to install the battery upper cover. Other-
wise, the battery electrolyte may spill and cause a
malfunction.


When installing the battery upper cover, plastic
nuts, and air duct, do not touch the cooling fan or
other moving parts in the engine compartment. Be
especially careful that the cables, your clothing or
hair, etc., do not get caught in the cooling fan or
other moving parts.

During cold weather
N00901600028
The battery is weaker in cold temperatures. This has to do with
its chemical and physical properties and is why a very cold bat-
tery, especially one with a low charge, will have a hard time
starting your vehicle.
It is recommended that you have your battery and charging sys-
tem checked by an authorized Mitsubishi Motors dealer or a
repair facility of your choice before the start of cold weather. If
necessary, have it charged. This will guarantee more reliable
starting, and longer battery life.
Disconnection and connection
N00901700029
To disconnect the battery cable, stop the engine. Disconnect the
negative (-) terminal first, then the positive (+) terminal. To
reconnect the battery, first connect the positive (+) terminal and
then the negative (-) terminal, before starting the vehicle. NOTE

For vehicles equipped with turbocharger, remove the bat-
tery upper cover before disconnecting the terminal of bat-
tery. Refer to “Removing and installing the battery upper
cover” on page 7-23.

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
N00940900202
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)
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”.

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.

Carbon monoxide gas from your vehicle’s exhaust is
poisonous. Breathing these fumes can cause uncon-
sciousness or death.

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
