Your vehicle is designed to use unleaded gasoline only. It is
equipped with a fuel filler tube especially designed to accept
only a small diameter unleaded gasoline dispensing nozzle. Gasoline detergent additivesIn the United States, fuel suppliers are required by law to add
detergents to their gasoline to minimize fuel-injector fouling
and minimize intake-valve deposits. Detergent gasoline helps
keep your engine in tune and your emission-control system
working properly.
Octane requirementExcept for RALLIARTYour vehicle is designed to operate on unleaded gasoline hav-
ing a minimum octane number of 87 [(MON+RON)/2], or 91
RON.RALLIARTYour vehicle is designed to operate on premium grade
unleaded gasoline having a minimum octane number of 93
[(MON+RON)/2] or higher for optimum performance. In case
premium grade unleaded gasoline 93 [(MON+RON)/2] is not
available, unleaded gasoline number of 91 [(MON+RON)/2]
can be used. However, the performance level is reduced.
In order to maintain exhaust system durability, premium
unleaded gasoline having an octane number of at least 91
[(MON+RON)/2] must be used.
If the premium grade unleaded gasoline number of 91
[(MON+RON)/2] or higher is not available on journey, etc.,
regular unleaded gasoline having an octane number of 87
[(MON+RON)/2] can be used temporarily as an emergency
measure.
MON: Motor Octane Number
RON: Research Octane Number Oxygenated gasoline Gasoline sold at some service stations contains oxygenates
such as ethanol and MTBE, 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.
WA R N I N G
!
Gasoline is highly flammable and explosive. You
could be burned, seriously injured or killed when
handling it. Whenever you refuel your vehicle, stop
the engine and keep flames, sparks, and smoking
materials away from the vehicle. Always handle fuel
in well-ventilated outdoor areas.
CAUTION
!
Using leaded gasoline in your vehicle will damage
the engine, catalytic converter, and the oxygen sen-
sors. Also, using leaded gasoline is illegal, and will
void your warranty coverage of the engine, catalytic
converter, and oxygen sensors.

Ethanol (Gasohol) A mixture of up to 10 % ethanol (grain alcohol) 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. Methanol Do not operate your vehicle on gasoline containing methanol
(wood alcohol). Using this type of alcohol could adversely
affect the vehicle’s performance and damage critical parts of
the vehicle’s fuel system.Reformulated gasoline Many areas of the country require the use of cleaner burning
fuel referred to as “Reformulated Gasoline”.
Reformulated gasoline contains oxygenates and is specially
blended to reduce vehicle emissions and improve air quality.
Mitsubishi Motors Corporation strongly supports the use of
reformulated gasoline. Properly blended reformulated gasoline
has no adverse effect on vehicle performance or the durability
of the engine and fuel system. MMT (methylcyclopentadienyl manganese tri-
carbonyl)MMT is a manganese-containing metallic additive that is
blended into some gasolines to increase the octane number.
Mitsubishi Motors Corporation recommends using gasolines
without MMT.
Use of gasolines blended with MMT may adversely affect per-
formance, and cause the malfunction indicator on your instru-
ment panel to come on. If this happens, contact an authorized
Mitsubishi Motors dealer or a repair facility of your choice for
assistance.
Sulfur in gasoline Your vehicle may have been designed to satisfy California’s
low-emission regulations based on clean-burning low-sulfur
gasoline. Gasoline sold in parts of the country other than Cali-
fornia is allowed to have a higher sulfur content. Using such
gasoline could adversely affect the vehicle’s catalytic converter
and cause the engine malfunction indicator (“SERVICE
ENGINE SOON” or “CHECK ENGINE”) to come on. Illumi-
nation of this indicator while you are using high-sulfur gaso-
line does not necessarily mean the vehicle’s emission-control
system is malfunctioning. Your authorized Mitsubishi Motors
dealer may suggest you try using a different, lower-sulfur
brand of unleaded gasoline to determine whether the problem
is fuel-related.NOTE
Poor-quality gasoline can cause problems such as poor
starting, stalling during idling, abnormal engine noise, and
poor acceleration. If you experience any of these prob-
lems, try using a different brand of gasoline. If the engine
malfunction indicator (“SERVICE ENGINE SOON” or
“CHECK ENGINE”) flashes, have the vehicle inspected
as soon as possible by the nearest authorized Mitsubishi
Motors dealer or a repair facility of your choice.

4. While filling with fuel, store the cap in the cap holder
located on the inside of the fuel tank filler door.
5. To fill with fuel correctly depends mainly on correct han-
dling of the fuel filler nozzle. Do not tilt the nozzle. Insert
the nozzle in the tank port as far as it will go.6. When the nozzle stops automatically, do not attempt to
add more fuel.
7. To close, turn the fuel tank filler cap slowly clockwise
until you hear clicking sounds, then gently push the fuel
tank filler door closed.
CAUTION
!
Your vehicle can only be operated using unleaded
gasoline. Serious engine and catalytic converter
damage will result if leaded gasoline is used.
CAUTION
!
To avoid fuel spillage and overfilling, do not “top-
off” the fuel tank. Spilled fuel could discolor, stain,
or crack the vehicle’s paintwork. If fuel spills on the
paintwork, wipe it off with a soft cloth.
WA R N I N G
!
Make sure the fuel cap is securely closed. If the fuel
cap is loose, fuel could leak, resulting in a fire.
CAUTION
!
If you need to replace the fuel tank filler cap, use
only the cap specified for your model vehicle.

7 Catalytic converter
N00937400131
The catalytic converter requires you to use unleaded fuel only.
Leaded gasoline will destroy the emission-control effective-
ness of the converter.
Normally, the catalytic converter does not require maintenance.
However, it is important to keep the engine properly tuned for
the converter to continue to work properly. To reduce the possibility of catalytic converter damage:

Use UNLEADED GASOLINE ONLY of the type of rec-
ommended in “Fuel selection”.

Do not drive with an extremely low fuel level. Running
out of gas could damage the catalytic converter.

Do not try to start the engine by pushing or towing the
vehicle. If the battery is weak or run down, use jumper
cables to properly start the engine.

Do not idle the engine with any spark plug wires discon-
nected or removed, such as when performing diagnostic
tests.

Do not idle the engine for a long time if it is idling
roughly or otherwise obviously malfunctioning.

To prevent the catalytic converter from being damaged
from unburned gas, do not race the engine when turning
off the ignition switch.

Stop driving the vehicle if you think the performance is
less than normal, the engine is running oddly or there is
any other engine trouble, such as with the ignition, etc. If
you are not able to stop driving immediately, slow down
and drive for only a short time. Have an inspection made
by an authorized Mitsubishi Motors dealer or a repair
facility of your choice as soon as possible.

In unusual situations involving major engine problems, a
burning odor may indicate severe and abnormal catalytic
converter overheating. If this occurs, stop in a safe place,
shut the engine off and let the vehicle cool. Once the
engine is cool, immediately take your vehicle to a dealer
or a repair facility of your choice for service.
CAUTION
!
Damage to the catalytic converter can result if your
vehicle is not kept in proper operating condition. If
the engine malfunctions or misfires, or if your vehi-
cle performance suffers, have it serviced promptly.
Running your vehicle when it is overheated may
result in damage to the converter and vehicle.
WA R N I N G
!
Do not park or run your vehicle in areas where com-
bustible materials such as dry grass or leaves can
come in contact with a hot exhaust, since a fire could
occur.
Do not put undercoat paint on the catalytic con-
verter.
