Your vehicle is designe
d to use unleaded gas-
oline only. It is equipped with a fuel tank filler pipe specifically
designed to accept only
a small diameter unlea
ded gasoline dispens-
ing nozzle. In the United States, fuel suppliers are required by law to add detergents to their gas-
oline to minimize fuel-injector clogging and minimize intake-valve
deposits. Detergent
gasoline helps keep your engine in tune and your emission-control system working prop- erly. Your vehicle is de
signed to operate on
unleaded gasoline having a minimum octane number of 87 [(MON+RON)/2] or 91 RON. Gasoline sold at some
service stations con-
tains oxygenates such as ethanol, although the oxygenates may not be
identified by those
names. Oxygenates
are required in some
areas of the country. Such fuel can be used in your vehicle. A mixture of up to 10 % ethanol (grain alco- hol) and 90 % unleaded
gasoline may be used
in your vehicle, provided the octane number is at least as high as that recommended for unleaded gasoline.
Do not operate your vehicle on gasoline con- taining methanol (wood alcohol). Using this type of alcohol could adversely affect thevehicle’s performance
and damage critical
parts of the vehicl
e’s fuel system.
Many areas of the country require the use of cleaner burning fuel referred to as “Reformu-lated Gasoline”. Reformulated gasoline
contains oxygenates
and is specially ble
nded to reduce vehicle
emissions and improve air quality. Mitsubishi Motors Corporation strongly sup- ports the use of reformulated gasoline. Prop-erly blended reformul
ated gasoline has no
adverse effect on vehicle performance or the durability of the engine and fuel system. MMT is a manganese-
containing metallic
additive that is ble
nded into some gasolines
to increase the octane number. Mitsubishi Motors Corporation recommends using gaso-lines without MMT.

WA R N I N G Gasoline is highly flammable and explo- sive. You could be burned, seriously injured or killed when handling it. When-ever you refuel your
vehicle, stop the
engine and keep fl
ames, sparks, and
smoking materials away from the vehicle.Always handle fuel in well-ventilated out- door areas.CAUTION Using leaded gasoline
in your vehicle will
damage the engine, ca
talytic converter, and
the oxygen sensors. Also, using leaded gaso- line is illegal, and
will void your warranty

, catalytic converter,
and oxygen sensors.

This vehicle should not be modified withnon-Mitsubishi Motors genuine parts. Mitsubishi Motors designs and manufactures high quality vehicles
with an emphasis on
safety and durability.
Modifications using
non-Mitsubishi Motors genuine parts may affect the performance, safety and/or durabil-ity of your vehicle,
and may violate applica-
ble state and/or fe
deral regulations.
DAMAGE OR PERFORMANCE PROB- LEMS RESULTING FROM MODIFICA-TIONS TO OR RACING OF YOUR
VEHICLE ARE NOT COVERED UNDER WARRANTY. Examples of modifications to your vehicle that can cause damage or performance prob- lems include the following:  Failure to use Mits
ubishi Motors genuine
parts Failure to use required fuel and fluids  Failure to use proper
size tires and wheels
 Modification of the fu
el, intake, exhaust,
emission, suspension,
engine, drive train
or electrical wiring systems Modification of any onboard com- puter/control module, including repro- gramming, or replac
ing/adding chips to
any onboard computer/control module

and Maintenance Man-
ual for further details

CAUTION To avoid fuel spillage
and overfilling, do not
“top-off” the fuel tank. Spilled fuel coulddiscolor, stain, or cr
ack the vehicle’s paint-
work. If fuel spills on the paintwork, wipe it off with a soft cloth.WA R N I N G Make sure the fuel tank filler cap is securely closed. If the fuel tank filler cap were loose, fuel coul
d leak, resulting in a
fire.CAUTION If you need to replace the fuel tank filler cap, use only the fuel tank filler cap specified for your model vehicle.
NOTE
 If the fuel tank filler cap is not tight while driving, the engine
malfunction indicator
(“SERVICE ENGINE SOON” or “Checkengine light”) may come on when the onboard diagnostic (OBD) system performs a self check.Always tighten the fu
el tank filler cap until
you hear at least 3 clicks. The indicator will go of
f after several driving
cycles. If the indicato
r does not go off, con-
tact your authorized
Mitsubishi Motors
dealer or a repair faci
lity of your choice as
soon as possible.

2. Set the air selection switch to the outside air position.3. Select your desired blower speed by pressing the blower speed selection switch.4. Select your desired temperature by press- ing the temperature control switch. 5. Push the air conditioning switch. For quick defrosting 1. Push the defogger switch to change to the “ ” position. 2. Set your blower to the maximum speed.3. Set the temperature to the highest posi- tion.

1. Park the vehicle in the shade whenever possible. Parking in the hot sun makes the vehicle interior extremely hot which then requires more time to cool. If it is neces-sary to park in the sun, open the windows for the first few minutes of air condition- ing to expel the hot air.2. Afterwards, keep the windows closed when the air conditioning is in use. The entry of outside air through open windowswill reduce cooling efficiency.
3. When running the air conditioning, make sure the air intake, which is located infront of the windshield, is free of obstruc- tions such as leaves. Leaves collected in the air-intake chamber may reduce airflow and plug the water drains.
If the air conditioning seems less effective than usual, the cause might be a refrigerant leak. Have the system inspected by your authorizedMitsubishi Motors dealer
or a repair facility
of your choice.
NOTE
 While the mode selection is set “ ” posi- tion, the air conditioning
compressor will run
automatically. The out
side air position will
also be selected automatically.
 If the mode selection is set “ ” position, you cannot turn the air conditioning off orselect the recirculati
on position. This pre-
vents the windows from fogging up.  To defog quickly, direct the air flow from the side vents toward the door windows.  When defrosting, do not set the temperature to the maximum cool position. This will blow cool air on the window glass and fog it up.

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.

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”.

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
Have the valve clea
rance checked at an
authorized Mitsubishi Motors dealer at the mileage specified in
the “WARRANTY AND
MAINTENANCE MANUAL”.If the engine sounds ab
normally loud, have
adjustments made by an authorized Mitsubishi Motors dealer.

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.
