The condition of the batte
ry is very important
for quick starting and to keep the vehicle’s electrical system working properly. Check thebattery regularly.
N00901500072
The electrolyte level
must be between the
limits shown on the outside of the battery. Fill it with distilled water as needed. The inside ofthe battery is divided into several compart- ments. Take the cap off of each compartment and fill to the mark.Do not fill above the top line because a spill during driving could cause damage.
N00901600060
The battery is weaker in cold temperatures. This has to do with its chemical and physical properties and is why a very cold battery, especially one with a lo
w charge, will have a
hard time starting your vehicle. It is recommended that you have your battery and charging system checked by an autho-rized Mitsubishi Motors dealer or a repair
facility of your choice
before the start of cold
weather. If necessary, have it charged. Thiswill provide more reliab
le starting, and longer
battery life.
N00901701169
To disconnect the battery cable, stop theengine. Disconne
ct the negative (-) terminal
first, then the positive
(+) terminal. To recon-
nect the battery, first
connect the positive (+)
terminal and then the negative (-) terminal,before starting the vehicle.
 Keep the reservoir cap closed to keep the brake fluid from evaporating.
Battery Checking battery electrolyte level
CAUTION
WA R N I N G If the battery goes flat, be sure to check the battery electrolyte level before con-necting booster cables. After checking the battery electrolyte level, make sure the caps are fitted securely. If any of the caps has a loose fit, replace the battery.
During cold weather
Disconnection and connection
NOTE
 Open the terminal cover (A) before discon- necting or connecting the positive (+) termi- nal of the battery.  Loosen the nut (B) and then disconnect the battery cable from the positive (+) terminal.

It is important to familiarize yourself with the following terms:Cold tire pressure:
WA R N I N G Never disconnect the battery while the engine is running, or you could damagethe vehicle’s electrical parts. Never short-circuit the battery. This could cause it to overheat and be damaged. Keep sparks, cigarette
s, and flames away
from the battery because the battery couldexplode. Electrolyte (battery acid) is made of corro- sive diluted sulfuric acid. If it spills on nearby parts, it can crack, stain, or dis- color them. And if it gets on your skin orin your eyes, it can cause burns or blind- ness. Please observe the following han- dling instructions:• If electrolyte gets on plastic parts orother nearby parts, wipe it off with a softcloth or chamois soak
ed in a solution of
water and neutral detergent then imme- diately rinse the affected parts withplenty of water.• If electrolyte gets on your hands orclothes, rinse thoroughly with water. If electrolyte gets in
your eyes, flush them
with water immediately and get immedi-ate medical attention.
 Open doors and wind
ows in any closed
space where you may be charging or working with the battery. Always wear protective clothing and gog- gles when working with the battery, or have a skilled automobi
le technician do it.
If you are quick-charging your battery, first disconnect the battery cables. In order to prevent a short-circuit, be sure to disconnect the negative (-) terminal first, and reconnect it last. Battery posts, termin
als and related acces-
sories contain lead
and lead compounds.
Wash hands after handling.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 cl
amps after cleaning or
tightening them.  Check to see that the battery is securely installed and cannot be
moved. Also check
each terminal for tightness.  If you will not be driv
ing your vehicle for a
long period of time, re
move the battery and
store it in a place where the battery fluid willnot freeze. The batter
y only should be stored
with a full charge.  Before cleaning the ba
ttery, tighten all the
filler port caps to keep
dirt and moisture out.
WA R N I N G
Tires
WA R N I N GDriving with tires that are worn, damaged or improperly inflated is dangerous.These type tire
conditions will
adversely affect vehicle perfor- mance.These type tire conditions can also cause a tread separation or blowout which may resultin an accident causing serious injury or death.Tires, including spare tire,degrade over time with age even when they are not beingused. It is recommended that tires over 6 years generally bereplaced even if damage is not obvious.

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 MAINTENANCE MANUAL”.
N00941000040
Check the hose surfaces for any heat and mechanical 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. 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.
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.
N00941300173
Check these regularly for damage or leaks in the fuel lines and connections. Check the fuel tank filler cap for dama
ge or looseness. Pay
special attention to the fuel lines closest to
high heat sources such
as the exhaust mani-
fold.
N00941400187
If the fuel-vapor vent line is clogged or dam-aged, the fuel-vapor mixture will escape, pol- luting the air. Have the system checked at an authorizedMitsubishi Motors dealer at the mileage spec- ified in the “WARRANTY AND MAINTE- NANCE MANUAL”.

The next pages list th
e maintenance service
recommended by Mitsubishi Motors Corpo-ration. In addition to the general maintenance that needs to be performed at the times listed,
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 that controls OBD functions stores various data (especially about th
e 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
NOTE
Use the spark plugs listed under “Engine specifications” on page 11
-5 or plugs that are
exactly the same. Other plugs could cause engine damage, performance problems orradio noise.

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.

5. Insert a new fuse
of the same capacity
securely into the appropriate slot.
N00942901362
Before replacing the bulb, be sure the light is off. Do not touch the glass part of the new bulb with your bare fingers; the oil from yourskin will stay on the
glass and dim or destroy
the bulb when it gets hot.
B- Fuse is OK C- Blown fuseCAUTION Never use a fuse with a capacity greater than the one listed or any s
ubstitute, such as wire,
foil etc. This would
cause the circuit wiring
to heat up and could cause a fire. If the replacement fuse blows again after a short time, have the electrical system checked by an authorized Mitsubishi Motors dealer or a repair faci
lity of your choice to
find and correct
the cause.
Replacement of light bulbs
CAUTIONBulbs are extremely hot immediately after being turned off. When replacing the bulb, wait for it to coolsufficiently before
touching it. You could
otherwise be burned. Handle halogen light bul
b with care. The gas
inside halogen light
bulb is highly pressur-
ized, so dropping, knocki
ng, or scratching a
halogen light bulb can
cause it to shatter.
Never hold the halogen
light bulb with a bare
hand, dirty glove, etc. The oil from your hand could cause the bulb to break the next time the headlights areused. If the glass surface is dirty, clean it with alcohol and let it dry completely beforeinstalling the bulb.
CAUTION Do not install commercially available LED- type bulbs. Commercially availa
ble LED-type bulbs
could adversely affect the operation of thevehicle, such as by preventing the lights and other vehicle equi
pment from operating
properly.NOTE
 If you are unsure of how to carry out the work as required, it is recommended that these procedures be ca
rried out by an autho-
rized Mitsubishi Motors
dealer or a repair
facility of your choice.  Be careful not to scratch the vehicle body when removing a light and lens.
