Taking regular care of your vehicle will pre- serve its value and appe
arance as long as pos-
sible. You can do some of the maintenance work yourself, and the rest should only be per- formed by an authorized Mitsubishi Motors dealer or a repair facility of your choice. If you discover a malfunction or other prob- lem, have it corrected by an authorizedMitsubishi Motors dealer
or a repair facility
of your choice. This section descri
bes the maintenance
inspections that you can do yourself, if you so desire. Follow the instructions and precau- tions for each procedure.
Have you purchased the Mitsubishi Motors Diamond Care Protection Plan? The Plan supplements your new
vehicle warranties.

Service precautions
WA R N I N G When checking or servicing the inside of the engine compartment, be sure the engine is stopped and has had a chance tocool down. If you need to work in the engine compart- ment with the engine running, be espe- cially careful that you
r clothing, hair, etc.
does not get caught in the fan, drive belts,or other moving parts.
 After performing the maintenance work, make sure that no tools or cloths are leftbehind in the engine compartment.If they are left behind, a fire or damage to the vehicle may occur. The fan can turn on automatically even if the engine is not running. Turn the igni- tion switch to the “OFF” position or putthe operation mode in OFF to be safe while you work in
the engine compart-
ment. Do not smoke or allow open flames around fuel or the battery. The fumes are flamma-ble. Be extremely careful when working around the battery. It
contains poisonous
and corrosive sulfuric acid. Do not get under your ve
hicle while it is on
a jack. Always use properly rated automotivejack stands. Handling your vehicle’s parts and materi- als in the wrong way can injure you. Ask an authorized Mitsub
ishi Motors dealer
or a repair facility of your choice if youhave questions.WA R N I N G

Catalytic converter
Vehicle care and maintenance 9-3
9
Only use the designated positions shown in the illustration.
N00937400450
The catalytic converter requires you to use unleaded fuel only. Leaded gasoline willdestroy the emission-control effectiveness of the converter. Normally, the
catalytic converter does not
require maintenance. Ho
wever, it is important
to keep the engine properly tuned for the con- verter to continue to work properly.
To reduce the possibili
ty of catalytic con-
verter damage:  Use UNLEADED GASOLINE ONLY of the type of recommended in the “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 disconnected 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 stopping the engine.
If your vehicle is raised with a garage jack *- Front of the vehicleWA R N I N G Set a garage jack only at the position shown here. If the gar
age jack is set a
wrong position, it could damage your vehicle and/or your
vehicle might fall
from the jack causing injury or death.
Never use the rear suspensions as a jack-ing point.
 Do not use the jack on a tilted or soft sur- face.Otherwise, the jack might slip and causepersonal injury. Always
use the jack on a
flat, hard surface. Before setting the jack, make sure there are no sand or pebblesunder the jack base.
Catalytic converter
CAUTION Damage to the catalytic
converter can result
if your vehicle is not
kept in proper operating
condition. If the engine
malfunctions or mis-
fires, or if your vehi
cle performance suffers,
have it serviced
promptly. Running your
vehicle when it is ove
rheated may result in
damage to the conve
rter and vehicle.
WA R N I N G
WA R N I N GDo not park or run your vehicle in areas where combustible materials such as drygrass or leaves can come
in contact with a
hot exhaust, since a fire could occur. Do not put undercoat paint on the cata- lytic converter.

Mitsubishi Motors recommends using only engine oils with the ILSAC certification sym- bol on the front of the container. If you cannot find oils
with the ILSAC certi-
fication symbol, use an API classification SN or higher oil with the following label.
This mark appears on the top of the oil con- tainer and tells you two important thingsabout the oil. Use engine oil with the proper thickness for the outdoor temperatures where you will bedriving.
CAUTION Overfilling will cause oil aeration and loss of oil pressure, which coul
d damage the engine.
WA R N I N GUsed engine oil is po
isonous, and can dam-
age your skin. Prolonged and repeatedcontact may cause serious skin disorders, including dermatitis and cancer. Do not let used oil touch your sk
in and wash thor-
oughly after working with it. Keep used oil out of
the reach of children.
NOTE
Engine oil consumption
is greatly influenced
by payload, engine speed, etc.
Good
 The engine oil wi
ll deteriorate rapidly if the
vehicle is subj
ected to severe conditions (for
example, repeated operation on rough roads,in mountainous regions, on roads with many uphill and downhill gradients, or over short distances). Consequently
, the oil will require
earlier replacement in accordance with the schedule in the “WARRANTY AND MAIN- TENANCE MANUAL”.

The radiator cap must be
sealed tight to pre-
vent losing coolant, which may result in engine damage. Only use a Mitsubishi Motors Genuine Parts radiator cap, or anapproved equivalent.
 Do not overfill the reservoir.  Your vehicle uses a special radiator cap that stays sealed and lets the coolant flow from the reservoir back to the radiatorwhen the engine cools down. If you need to change the cap, use the exact same kind.
 Check the coolant freeze point in the radi- ator with the proper gauge, and only whenit is safe. If you add antifreeze, the con- tents of the reservoi
r must be protected
against freezing. Keep the front of the radiator and con- denser clean.  If the engine coolan
t temperature does not
rise after the engine
is warmed-up, take
your vehicle to an au
thorized Mitsubishi
Motors dealer or a repair facility of your choice to have the thermostat checked, and replaced if necessary.
N00937901540
The air cleaner filter
will get dirty and dusty
from use and not filter
properly. Replace it
with a new filter using the schedule in the “WARRANTY AND MAINTENANCE MANUAL”.
 The required concentrati
on of anti-freeze dif-
fers depending on the
expected ambient tem-
perature.Above -31 °F (-35 °C) : 50 % concentration of anti-freeze Below -31 °F (-35 °C) : 60 % concentrationof anti-freeze You can check the concentration level with a gauge from an automotive supply store, oryour authorized Mitsubi
shi Motors dealer or
service station can check it for you. Do not use water to adjust the concentration of coolant. Do not top off the reservoir with plain water only. Water by itself bo
ils at a lower temper-
ature and does not stop rust or freezing. If thewater freezes, it will
damage your cooling
system. Do not use tapwater. It can cause corrosion and rust.
Radiator cap
CAUTION
WA R N I N G Wait for the engine to cool down before opening the radiator
cap. Otherwise hot
steam or boiling c
oolant could spray up
from the filler po
rt and scald you.

The best way to keep carbon monoxide gas from entering inside your
vehicle is to have
the engine exhaust syst
em properly serviced.
Have a competent mechanic inspect the com- plete exhaust system
and nearby body areas
for broken, damaged, deteriorated, or mispo- sitioned parts if you no
tice any of the follow-
ing:  A change in the sound of the exhaust sys- tem  The smell of exhaust fumes inside the vehicle
 The underside or rear of the vehicle is damaged
Also check the exhaust system each time the vehicle is raised for l
ubrication, oil changes,
or required service. A
ny open seams or loose
connections could le
t dangerous exhaust
fumes seep into the luggage and passenger compartments.  Check for holes or exhaust gas leaks caused by corrosion or damage.  Check the joints and connections for looseness or exhaust gas leaks. Check the rubber hangers and brackets for damage.
