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.
WARNING
!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.

Engine oil identification markMitsubishi Motors recommends using only engine oils with the
ILSAC certification symbol on the front of the container.If you cannot find oils with the ILSAC certification symbol,
use an API classification SM or higher oil with the following
label.
This mark appears on the top of the oil container and tells you
two important things about the oil.ILSAC certification symbol
1- The top portion shows the quality of the oil.
2- The center portion shows the SAE grade of the oil viscosity.API service symbol

Recommended engine oil viscosity
N00955000041
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.Except for vehicles with turbochargerSAE 5W-20 engine oil is strongly recommended for optimum
fuel economy and cold starting.
SAE 10W-30 may be used when the normal operating tempera-
ture is above 100 °F (38 °C).
Vehicles with turbochargerNOTESelect engine oil of the proper SAE viscosity number
according to the atmospheric temperature. SAE 5W-30,
0W-30 and 0W-40 engine oil can only be used if it meets
API SM (or higher) specifications.
SAE 0W-30 and 0W-40 engine oil are recommended to
use to improve engine startability on a very cold weather
condition.
SAE 10W-30 may be used when the normal operating
temperature is above 100 °F (38 °C).
Use engine oil conforming to the following classification:
• API classification: “For service SM” or higher
• ILSAC certificated oil

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.

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.

Treadwear, Traction and Temperature GradesTr e a d w e a r
The treadwear grade is a comparative rating based on the
wear rate of the tire when tested under controlled conditions
on a specified government test course. For example, a tire
graded 150 would wear one and one-half (1
1/2) times as
well on the government course as a tire graded 100. The rel-
ative performance of tires depends upon the actual condi-
tions of their use, however, and may depart significantly
from the norm due to variations in driving habits, service
practices and differences in road characteristics and climate.
Traction
The traction grades, from highest to lowest, are AA, A, B
and C. Those grades represent the tire’s ability to stop on
wet pavement as measured under controlled conditions on
specified government test surfaces of asphalt and concrete.
A tire marked C may have poor traction performance.
Te m p e r a t u r e
The temperature grades are A (the highest), B and C, repre-
senting the tire’s resistance to the generation of heat and its
ability to dissipate heat when tested under controlled condi-
tions on a specified indoor laboratory test wheel. Sustained
high temperature can cause the material of the tire to degen-
erate and reduce tire life, and excessive temperature can
lead to sudden tire failure. The grade C corresponds to a
level of performance which all passenger car tires must
meet under the Federal Motor Vehicle Safety Standard No.
109. Grades B and A represent higher levels of performance
on the laboratory test wheel than the minimum required by
law.
Tire inflation pressures
N00939300730
Proper tire inflation pressure is essential for the safe and satis-
factory operation of your vehicle. The wrong tire pressure will
cause problems in three major areas:
Safety
Too little pressure increases flexing in the tire and can
cause tire failure. Too much pressure can cause a tire to
lose its ability to cushion shock. Objects on the road and
potholes could then cause tire damage that may result in
tire failure.
Economy
The wrong tire pressure can cause uneven wear patterns in
the tire tread. These abnormal wear patterns will reduce
the tread life, and the tire will have to be replaced sooner.
Too little pressure also makes it harder for the tire to roll,
and this uses up more fuel.
Ride comfort and vehicle stability
The superior riding experience built into your vehicle
partly depends on the correct tire pressure. Too much
pressure gives an uncomfortable and jarring ride. Too lit-
tle pressure feels as if your vehicle is slow to respond.
Unequal tire pressures can make steering your vehicle
uneven and unpredictable.
The correct tire pressure for your vehicle is listed on the plac-
ard attached to the sill of the driver’s door.
