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: • The measured pressure after the vehicle has been parked for
at least three hours,
or• The measured pressure when the vehicle is driven less than 1 mile (1.6 km) after having been parked for three hours.
 Maximum pressure: the maximum per- missible cold tire inflation pressure for this tire.
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 performance. These type tire conditions can also cause atread separation or blowout which may result in an accide
nt causing serious
injury or death. Tires, including spar
e tire, degrade over
time with age even when they are notbeing used. It is recommended that tires over 6 years generally be replaced even if damage isnot obvious.

In some areas of the country, snow tires are required for winter driv
ing. If snow tires are
required in your area, you must choose snowtires of the same size
and type as the original
tires provided with your
vehicle. Snow tires
should also be installe
d on all four wheels.
Otherwise your safety
and vehicle handling
can be reduced. Even where laws may permit it, snow tires should not be operated
at sustained speeds
over 75 mph (120 km/h).

Clutch pedal free play: .4 to .6 inch (11 to 16 mm) If the free play is not within these limits, take your vehicle to an authorized Mitsubishi Motors dealer or a repair facility of yourchoice for adjustment.
CAUTION If the tires have arrows (A) indicating the correct direction of rotation, swap the frontand rear tires on the left-hand side of thevehicle and the front and rear tires on the right-hand side of th
e vehicle separately.
Keep each tire on its original side of thevehicle. When installi
ng the tires, make sure
the arrows point in the direction in which the wheels will turn when the vehicle moves for-ward. Any tire whose
arrow points in the
wrong direction will not
perform to its full
potential.CAUTION Avoid the combined use of different types of tires. Using different t
ypes of tires can affect
vehicle performance and safety.
Front
Snow tires
CAUTION If your vehicle is equipped with a tire pres- sure monitoring system, only Mitsubishi Motors Genuine whee
ls should be used.
Use of another type of wheel risks air leaks and sensor damage, as it
will not be possible
to install the tire pressure sensor properly.
Tire chains
CAUTION Tire chains cannot be used on your vehicle. The clearance between
the chains and the
body is not sufficient
to allow proper clear-
ance, and the vehicle body might be dam- aged.

N00940800328
Your vehicle is equi
pped with an emission-
control system that me
ets all the requirements
of the U.S. Environmental Protection Agencyand Environment Cana
da. The emission-con-
trol system is made of:  a positive crankcase ventilation system  an evaporative emission-control system  an exhaust emission-control system
To be sure the emission-control system works properly, have your vehicle inspected andmaintained by an authorized Mitsubishi Motors dealer or a repair facility of your choice. This should be
done at the time or
mileage specified in the “WARRANTY AND MAINTENANCE MANUAL”. These, and all the other “general” mainte-nance services listed in this manual, need to be performed to keep your vehicle running properly and reliably.You should also have an inspection and ser- vice any time you
suspect a malfunction.
N00940900228
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, ha
rd 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 andcouplings, to make sure they are secure and that there are no leaks. If you see any wear or damage, replace the hoses immediately.
N00950100050

Emission-control system maintenance
NOTE
 To meet government
regulations and pro-
mote cleaner air, your
vehicle is equipped
with an onboard diagnostic system (OBD).The engine electroni
c 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 c
ould make a rapid
diagnosis difficult.
Do not disconnect the
battery cable when the engine malfunction indicator (“SERVIC
E 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. Othe
r plugs could cause
engine damage, perf
ormance problems or
radio noise.

The best way to keep carbon monoxide gas from 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, de
teriorated, or mispo-
sitioned parts if you not
ice any of the follow-
ing:  A change in the sound of the exhaust sys- tem  The smell of exhaust fumes inside the vehicle
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 hood safety catch should be checked, cleaned, andoiled when needed fo
r easy movement and to
prevent rust and wear. Use Multipurpose Grease 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 mo
vable surfaces are cov-
ered.Also, put a light coat of the same grease on the safety catch wherev
er 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 heating and ventilation systems
will not be impaired.
To prevent freezing of the weatherstripping on the doors, engine hood, etc., they should be 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 sweeping
snow off the vehicle a
nd a plastic scraper for
the windshield, side and rear window are alsouseful.
N00942700305
The fusible links will melt to prevent a fire ifa large current attempts
to flow through cer-

Use a soft cloth to put a small amount of wax on the painted surfaces. After the wax hasdried, polish with a dry soft cloth. Do not wax your vehicle
in direct sunlight.
You should wax when the painted surfacesare cool.
N00946100046
If painted surfaces ha
ve been severely dam-
aged and lost their original luster and color tone, polish the surface lightly with a finepolishing compound. Avoid limiting your polishing to the damage
d surface only; polish
a somewhat wider area, moving the polishing
cloth in one direction.
After polishing, flush
the compound from the surface and apply acoat of wax to regain a beautiful luster.
N00946200092
Small cracks and scratches in the paint coatshould 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 damage to the paint caused by flying stones, etc. The paint code number foryour vehicle can be found on the vehicle information code plate
on the front passenger
door sill.
N00946300194
Use a sponge or chamoi
s 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 waterand a soft cloth or chamois.
N00946400052
To prevent spots and corrosion of chromeparts, wash with water, dry thoroughly, andapply a nonabrasive automotive wax. If the chrome is severely damaged or pitted, use a commercially available chrome polish.
N00946501236
1. Remove dirt using a wet sponge.2. Use a mild detergent
on any dirt that can-
not be removed easily with water. Rinse off the detergent after washing the wheels.3. Dry the wheels thoroughly using a cham- ois leather or a soft cloth.
CAUTION Waxes containing high abrasive compounds should not be used. These waxes remove rustand stain effectively from the paintwork, but are harmful to the finish of the paint, because they 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 or paint thinners to remove road tar or other dirt from the vehicle surface. Do not put wax on the areas having black matte coating because
it can cause uneven
discoloration, patches, bl
urs, etc. If these get
wax on them, wipe the wax off right away with a soft clot
h and warm water.
Polishing
Damaged paint Cleaning plastic parts
CAUTION Do not use a scrubbing brush or other rough scrubber as these may damage the plastic surface.
 Do not use wax containing compounds (pol- ishing powder) which
may damage the plas-
tic surface. Do not let plastic parts
get soiled with gaso-
line, oil, brake fluids, engine oils, greases,paint thinner, and sulfuric acid (battery elec- trolyte), as such substa
nces will cause stains,
cracks, or discoloration.If any of these get on a plastic part, wipe them up with a soft cloth or chamois and a mild solution of soap and water. Then rinsethem immediately with water.
