7 Catalytic converter
N00937400346
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
noticeably low, or the engine has a malfunction 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 your vehicle checked at 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.

7 Wiper blades
N00940700138
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.NOTEDo 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
N00940800328
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
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. This
should be done at the time or mileage specified in the “WAR-
RANTY AND MAINTENANCE MANUAL”.
These, and all the other “general” maintenance services listed
in this manual, need to be performed to keep your vehicle run-
ning properly and reliably.
You should also have an inspection and service any time you
suspect a malfunction.NOTETo 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 engine malfunction indicator (“SERVICE
ENGINE SOON” or “Check engine light”) is ON.
