7 Catalytic converter
N00937400333
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 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
noticeably low, or the engine has a malfunction. 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.

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.

7Automatic transaxle fluid
N00938000538
The automatic transaxle should be maintained and serviced by
an authorized Mitsubishi Motors dealer or a repair facility of
your choice to obtain the best performance and longest life. It
is important that the transaxle fluid is kept at the correct level. To check the fluid level The fluid level should be checked when the engine temperature
gauge shows the engine is warmed up and the fluid in the tran-
saxle is heated to its normal working temperature. Driving with
the wrong fluid level will rapidly wear out the transaxle and
destroy the fluid.
Procedure for checking the fluid level 1. With the brake pedal fully depressed and the engine
idling, select each gear momentarily, ending with the
selector lever in the “P” (PARK) position.
2. The fluid level should be at the HOT mark, but never
above the HOT mark when the engine is warmed up. Add
or drain fluid to get to the correct level.
3. Make certain that the dipstick cap is installed properly to
keep dirt and water out of the transaxle.
WA R N I N G
!
Transaxle fluid is extremely flammable and poison-
ous. Do not spill fluid when adding or draining.

Size Designation
EXAMPLE:P215/65R15

NOTE

European/Japanese metric tire sizing is based on
European/Japanese design standards. Tires designed
to these standards have the tire size molded into the
sidewall beginning with the section width. The letter
“P” is absent from this tire size designation. Exam-
ple: 215/65R15 96H.

LT (Light Truck) -metric tire sizing is based on
U.S.A. design standards. The size designation for
LT-metric tires is the same as for P-metric tires
except for the letters “LT” that are molded into the
sidewall preceding the size designation. Example:
LT235/85R16.


Temporary spare tires are high pressure compact
spares designed for temporary emergency use only.
Tires designed to this standard have the letter “T”
molded into the sidewall preceding the size designa-
tion. Example: T145/80D18 103M.Service Description

Maximum Pressure
Maximum Pressure indicates the maximum permissible
cold tire inflation pressure for this tire.
Tire Identification Number (TIN)
The TIN may be found on one or both sides of the tire but
the date code may only be on one side. Look for the TIN
on the outboard side of tires as mounted on the vehicle. If
the TIN is not found on the outboard side then you will
find it on the inboard side of the tire.
EXAMPLE: DOT MA L9 ABCD 1504

Treadwear, Traction and Temperature GradesTreadwear
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 relative perfor-
mance of tires depends upon the actual conditions 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.
Tr a c t i o n
The traction grades, from highest to lowest, are AA, A, B and
C. Those grades represent the tire’s ability to stop on wet pave-
ment as measured under controlled conditions on specified
government test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
Temperature
The temperature grades are A (the highest), B and C, represent-
ing the tire’s resistance to the generation of heat and its ability
to dissipate heat when tested under controlled conditions on a
specified indoor laboratory test wheel. Sustained high tempera-
ture can cause the material of the tire to degenerate and reduce
tire life, and excessive temperature can lead to sudden tire fail-
ure. The grade C corresponds to a level of performance which
all passenger car tires must meet under the Federal Motor Vehi-
cle Safety Standard No. 109. Grades B and A represent higher
levels of performance on the laboratory test wheel than the
minimum required by law.

7 Wiper blades
N00940700011
Check the wiper blades occasionally. Clean them regularly to
remove deposits of salt and road film. Use a sponge or cloth
and a mild detergent or non-abrasive cleaner to clean the blades
and glass areas.
Replace the blades if they continue to streak or smear.NOTE
Do not run the wipers on dry glass for a long time. This
wears out the rubber and can scratch the glass.During cold weatherIf the blades are frozen to the windshield or rear window, do
not operate the wipers until the ice has melted and the blades
are freed, otherwise the wiper motor may be damaged.
Emission-control system maintenance
N00940800272
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 malfunction indicator light (“SERVICE
ENGINE SOON” or “Check engine light”) is on.Spark plugs
N00940900127
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 MAINTE-
NANCE MANUAL”.
Your vehicle may be 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 9-6 or plugs that are exactly the same. Other
plugs could cause engine damage, performance problems
or radio noise.Fuel hoses
N00941000011
Check the hose surfaces for any heat and mechanical damage,
hard and brittle rubber, cracking, tears, cuts and abrasions. Payspecial 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.
Fuel system (tank, pipe line and connection, and
fuel tank filler tube cap)
N00941300144
Check these regularly for damage or leaks in the fuel lines and
connections. Check the fuel tank filler tube cap for damage or
looseness. Pay special attention to the fuel lines closest to high
heat sources such as the exhaust manifold.Evaporative emission control system (except
evaporative emission canister)
N00941400158
If the fuel-vapor vent line is clogged or damaged, the fuel-
vapor mixture will escape, polluting the air.
Have the system checked at an authorized Mitsubishi Motors
dealer at the mileage specified in the “WARRANTY AND
MAINTENANCE MANUAL”.
WA R N I N G
!
If you see a fuel leak or if you smell fuel, do not run
the engine. Any spark (including from the ignition),
flame or smoking material could cause an explosion
or fire. Call an authorized Mitsubishi Motors dealer
or a repair facility of your choice for assistance.
