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.

NOTE
Check each battery terminal for corrosion. You can stop
more corrosion by washing with a solution of baking soda
and water. Grease the posts and clamps after cleaning or
tightening them.

Check to see that the battery is securely installed and can-
not be moved. Also check each terminal for tightness.

If you will not be driving your vehicle for a long period of
time, remove the battery and store it in a place where the
battery fluid will not freeze. Memory data for settings
made by the user may be erased when the battery is
removed. If this happens, reset the settings again using the
relevant procedures. The battery only should be stored
with a full charge.

Before cleaning the battery, tighten all the filler port caps
to keep dirt and moisture out.
WA R N I N G
!
Never disconnect the battery while the engine is run-
ning, or you could damage the vehicle’s electrical
parts.
Never short-circuit the battery. This could cause it
to overheat and be damaged.
Keep sparks, cigarettes, and flames away from the
battery because the battery could explode.
Electrolyte (battery acid) is made of corrosive
diluted sulfuric acid. If it spills on nearby parts, it
can crack, stain, or discolor them. And if gets on
your skin or in your eyes, it can cause burns or
blindness. Please observe the following handling
instructions:
• If electrolyte gets on plastic parts or other nearby
parts, wipe it off with a soft cloth or chamois
soaked in a solution of water and neutral detergent
then immediately rinse the affected parts with
plenty of water.
• If electrolyte gets on your hands or clothes, rinse
thoroughly with water. If electrolyte gets in your
eyes, flush them with water immediately and get
immediate medical attention.

Open doors and windows in any closed space where
you may be charging or working with the battery.
Always wear protective clothing and goggles when
working with the battery, or have a skilled automo-
bile technician do it.
If you are quick-charging your battery, first discon-
nect the battery cables.

In order to prevent a short circuit, be sure to discon-
nect the negative (-) terminal first, and reconnect it
last.
If the electrolyte level is very low, have the battery
checked at an authorized Mitsubishi Motors dealer
or a repair facility of your choice.
Battery terminals and related accessories contain
lead and lead compounds. Wash hands after han-
dling.
