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.

Only use the designated positions shown in the illustration.
N00937400450
The catalytic converter requires you to use unleaded fuel only. Leaded gasoline willdestroy the emission-control effectiveness of the converter. Normally, the
catalytic converter does not
require maintenance. Ho
wever, it is important
to keep the engine properly tuned for the con- verter to continue to work properly.
To reduce the possibili
ty of catalytic con-
verter damage:  Use UNLEADED GASOLINE ONLY of the type of recommended in the “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 disconnected 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 stopping the engine.
If your vehicle is raised with a garage jack *- Front of the vehicleWA R N I N G Set a garage jack only at the position shown here. If the gar
age jack is set a
wrong position, it could damage your vehicle and/or your
vehicle might fall
from the jack causing injury or death.
Never use the rear suspensions as a jack-ing point.
 Do not use the jack on a tilted or soft sur- face.Otherwise, the jack might slip and causepersonal injury. Always
use the jack on a
flat, hard surface. Before setting the jack, make sure there are no sand or pebblesunder the jack base.
Catalytic converter
CAUTION Damage to the catalytic
converter can result
if your vehicle is not
kept in proper operating
condition. If the engine
malfunctions or mis-
fires, or if your vehi
cle performance suffers,
have it serviced
promptly. Running your
vehicle when it is ove
rheated may result in
damage to the conve
rter and vehicle.
WA R N I N G
WA R N I N GDo not park or run your vehicle in areas where combustible materials such as drygrass or leaves can come
in contact with a
hot exhaust, since a fire could occur. Do not put undercoat paint on the cata- lytic converter.

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,
there are other parts which do not usually need regular maintenance.But, if any of these parts stops working prop- erly, your vehicle performance could suffer. Have these items checked if you notice aproblem with them. If you have any questions, see your autho- rized Mitsubishi Motors
dealer for assistance.

Good brakes are essential for safe driving. Check the brake pads for wear. For goodbraking performance, re
place the brake pads
with the same type pads as the originals.
N00941700076
Brake hoses and tubing should be checkedfor:  Severe surface cracking, scuffing or worn spots. If the fabric casing of the hose isshowing through any cracks or worn spots in the rubber hose cover, the hose should be replaced. The brakes can fail if thehose wears through.  Improper installation
may cause twisting,
or wheel, tire or chassis interference.
N00941800077
Check the following parts for damage andgrease leaks:  Ball joint boots of the front suspension and steering linkage  Bellows on both ends of the drive shaft

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.

WA R N I N G Carbon monoxide gas
from your vehicle’s
exhaust is poisonous. Breathing thesefumes can cause unconsciousness or death.
