To replace the oil filter
N00955100013
The oil filter should be replaced at the time or mileage speci-
fied in the “WARRANTY AND MAINTENANCE MAN-
UAL”.
Only use high quality replacement filters on this vehicle. The
manufacturer’s specifications for Genuine Mitsubishi oil filters
require that the filter can withstand a pressure of 256 psi
(1.8 MPa). A Genuine Mitsubishi oil filter is the best replace-
ment filter.
Follow the installation instructions printed on the filter.
Engine coolant
N00937800438
To check the coolant level The coolant reserve tank (A) lets you quickly see when you
need to add coolant. When the engine is cold, the level in the
reserve tank should be between the “FULL” and “LOW”
marks. The radiator usually stays full so there is no reason to
remove the radiator cap (B) except when you check the coolant
freeze point or replace the antifreeze coolant.

To add coolant Use Mitsubishi Genuine Coolant or an equivalent.
Mitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum, and prevents blockages in the radiator, heater, cyl-
inder head, engine block, etc.
If you need to add coolant often, or if the level in the reserve
tank does not drop when the engine cools, the cooling system
should be pressure-tested for leaks. Take your vehicle to an
authorized Mitsubishi Motors dealer or a repair facility of your
choice for testing.
Radiator capThe radiator cap must be tight sealed to prevent losing coolant
which may result in engine damage. Only use a Genuine Mit-
subishi Parts radiator cap, or an approved equivalent.Points to remember
Do not overfill the reserve tank.
Your vehicle uses a special radiator cap that stays sealed
and lets the coolant flow from the reserve tank back to the
radiator when the engine cools down. If you need to
change the cap, use the exact same kind.
Check the coolant freeze point in the radiator with the
proper gauge, and only when it is safe. If you add anti-
freeze, the contents of the reserve tank must be protected
against freezing.
Keep the front of the radiator and condenser clean.
CAUTION
!
Do not use alcohol or methanol antifreeze or any
engine coolants that contain them. Using the wrong
antifreeze can corrode aluminum parts.
When you need to add coolant to the reserve tank,
use at least a 50 % concentration of ethylene-glycol
antifreeze in water. Do not overfill. Use a higher con-
centration (not over 60 %) when the outside temper-
ature is -31 °F (-35 °C) or lower. When the engine is
working very hard (for example, during mountain
driving and/or when the outside temperature is
high), use a 50 % concentration. You can check the
concentration level with a gauge from an automotive
supply store, or your authorized Mitsubishi Motors
dealer or service station can check it for you. Use
only high quality ethylene-glycol antifreeze coolant
that is made to prevent corrosion of all cooling sys-
tem metals.
Do not top off the tank with plain water only. Water
by itself boils at a lower temperature and does not
stop rust or freezing. If the water freezes, it will
damage your cooling system. Do not use tapwater. It
can cause corrosion and rust. WA R N I N G
!
Wait for the engine to cool down before opening the
radiator cap. Otherwise hot steam or boiling coolant
could spray up from the radiator and scald you. CAUTION

If the temperature of the engine coolant does not rise after
the engine is warmed-up, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice to have the thermostat checked, and replaced if
necessary.
Air cleaner filter
N00937900309
The air cleaner filter will get dirty and dusty from use and not

The windshield washer fluid reservoir is in the trunk.
Check the washer fluid level at regular intervals and add
washer fluid to reservoir if necessary. NOTE
Do not spill the fluid onto the trunk. If the fluid spilled,
wipe it up immediately.
During cold weatherWhen freezing weather is anticipated, flush out the water in the
reservoir by operating the pump. Fill the reservoir with wind-
shield antifreeze (not radiator antifreeze), and operate the sys-
tem for a few seconds to flush out the residual water.
Brake fluid/Clutch fluid
(if so equipped)
N00938700232
The brake fluid and the clutch fluid share the reservoir tank.To check the fluid levelThe fluid level must be between the “MAX” and “MIN” marks
on the reservoir.
The fluid level falls slightly with wear of the brake pads, but
this does not indicate any abnormality.
The fluid in the master cylinder should be checked when doing
other work under the engine hood. The brake system should
also be checked for leaks at the same time.
If the fluid level falls markedly in a short length of time, it indi-
cates leaks from the brake system.
If this occurs, have the vehicle checked by an authorized Mit-
subishi Motors dealer or a repair facility of your choice.

Power steering fluid
N00939000245
To check the fluid levelCheck the fluid level in the reservoir while the engine is idling.
Check to make certain that the power steering fluid level is
always between the “MAX” and “MIN” level markings on the
fluid reservoir and refill the fluid, if necessary.Fluid type
CAUTION
!
Do not let any petroleum-based fluid touch, mix
with, or get into the brake fluid. This will damage
the seals.
Be careful when handling brake fluid. It can damage
painted surfaces.
Use only the listed brake fluid. Different brands of
brake fluid have different additives, and these can
cause a chemical reaction. Do not mix brands of
brake fluid.
Keep the reservoir tank cap closed to keep the brake
fluid from evaporating.

7Battery
N00939100725
The vehicle battery is installed in the trunk behind a panel.
The condition of the battery is very important for quick starting
and to keep the vehicle’s electrical system working properly.
Be sure to have an authorized Mitsubishi Motors dealer check
the battery.
During cold weatherThe 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 before
the start of cold weather. If necessary, have it replaced.Disconnection and connectionTo 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.
WA R N I N G
!
Be sure to have an authorized Mitsubishi Motors
dealer charge the battery. Do not charge the battery
yourself, as it should only be charged after first
being removed from the vehicle.
In addition, never remove the battery label, upper
cover, exhaust tube, or pipe. Flammable gases may
leak and explode.
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.

Snow tires
N00940000359
In some areas of the country, snow tires are required for winter
driving. If snow tires are required in your area, you must
choose snow tires of the same size and type as the original tires
provided with your vehicle. Snow tires should also be installed
on all four wheels. Otherwise your safety and vehicle handling
can be reduced.
Even where laws may permit it, snow tires should not be oper-
ated at sustained speeds over 75 mph (120 km/h).Tire chains
N00940100015
Clutch pedal free play
(if so equipped)
N00940200045
To check the clutch pedal free play (A), turn off the engine and
press the pedal until you feel resistance.
Clutch pedal free play:
.2 to .5 inch (6 to 13 mm)
CAUTION
!
If flange nuts are used on your vehicle, change to
tapered nuts when using snow tires with steel
wheels.
Only Mitsubishi Motors genuine wheels should be
used, because your vehicle is equipped with a tire
pressure monitoring system.
Use of another type of wheel risks air leaks and sen-
sor damage, as it will not be possible to install the
tire pressure sensor properly.CAUTION
!
Tire chains cannot be used on your vehicle. The
clearance between the chains and the body is not
sufficient to allow proper clearance, and the vehicle
body might be damaged.

7 Emission-control system maintenance
N00940800201
Your vehicle is equipped with an emission-control system that
meets all the requirements of the U.S. Environmental Protec-
tion Agency and Environment Canada. The emission-control
system is made of:
a positive crankcase ventilation system
an evaporative emission-control system
an exhaust emission-control system
The maintenance services listed in the “WARRANTY AND
MAINTENANCE MANUAL” must be performed at the times
or mileages listed to keep the emission-control system working
properly. These, and all the other “general” maintenance ser-
vices listed in this manual, need to be performed to keep your
vehicle running properly and reliably.
You may need more frequent maintenance if you drive your
vehicle in harsh conditions such as dusty areas or do a lot of
start-and-stop driving.
To be sure the emission-control system works properly, have
your vehicle inspected and maintained by an authorized Mit-
subishi Motors dealer or a repair facility of your choice follow-
ing the schedule in the “WARRANTY AND MAINTENANCE
MANUAL”.
You should also have an inspection and service any time you
suspect a malfunction.
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.

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 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 9-7 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)
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.
