To check the battery indicator
N00901400039
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
N00901600015
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
N00901700016
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.

Open the terminal cover (A) before disconnecting or con-
necting the positive (+) terminal of the battery.

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.
WARNING
!
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
N00940900198
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.

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.
Aluminum wheels (if so equipped)
N00946500196
1. Remove dirt using a wet sponge.
2. Use a mild detergent on any dirt that cannot be removed
easily with water.
Rinse off the detergent after washing the wheel.
3. Dry the wheel thoroughly using a chamois leather or a soft
cloth.Window glass
N00946600067
The window glass can usually be cleaned using only a sponge
and water. Glass cleaner can be used to remove wax, oil,
grease, dead insects, etc. After washing the glass, wipe it dry
with a clean, dry, soft cloth.
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.
CAUTION
!
Do not use a brush or other hard implement on the
wheels.
Doing so could scratch the wheels.
