7 Catalytic converter
N00937400418
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. 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 an autho-
rized Mitsubishi Motors 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.

7Battery
N00939100725
The vehicle battery is installed in the trunk behind a panel.
The condition of the battery is very important for quick starting
and to keep the vehicle’s electrical system working properly.
Be sure to have an authorized Mitsubishi Motors dealer check
the battery.
During cold weatherThe battery is weaker in cold temperatures. This has to do with
its chemical and physical properties and is why a very cold bat-
tery, especially one with a low charge, will have a hard time
starting your vehicle.
It is recommended that you have your battery and charging sys-
tem checked by an authorized Mitsubishi Motors dealer before
the start of cold weather. If necessary, have it replaced.Disconnection and connectionTo disconnect the battery cable, stop the engine. Disconnect the
negative (-) terminal first, then the positive (+) terminal. To
reconnect the battery, first connect the positive (+) terminal and
then the negative (-) terminal, before starting the vehicle.
WA R N I N G
!Be sure to have an authorized Mitsubishi Motors
dealer charge the battery. Do not charge the battery
yourself, as it should only be charged after first
being removed from the vehicle.
In addition, never remove the battery label, upper
cover, exhaust tube, or pipe. Flammable gases may
leak and explode.
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.

7 Emission-control system maintenance
N00940800201
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
Mitsubishi Motors dealer or a repair facility of your choice fol-
lowing the schedule in the “WARRANTY AND MAINTE-
NANCE MANUAL”.
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.
