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.

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.

 Stop driving the vehicle if you think the performance is noticeably low, or theengine 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 yourchoice as soon
as possible.
 In unusual situations involving major engine problems, a burning odor may indicate severe a
nd 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 ser- vice.

It is normal for an engi
ne to use oil. You may
need to add oil betwee
n the recommended oil
change intervals. Before starting the engine,check the engine oil level. Refill if necessary. To check the oil level, remove the dipstick, wipe it off, and gently
reinsert it all the way.
Slowly pull the dipsti
ck straight out and
check the oil level by checking the upper sur- face of the dipstick. Th
e oil level must not go
above the line on the dipstick. If the level does not reach the line which shows the minimum amo
unt of oil required,
remove the oil filler cap on the engine valve cover, and fill to within the “Good” range.
To close
CAUTION Be careful not to trap your hands or fingers when closing the engine hood. Make sure the engine hood is firmly closed before driving.If you drive without the engine hood com- pletely closed, it c
ould open up while driv-
ing.
NOTE
 If this does not clos
e the engine hood prop-
erly, drop it again from a slightly higherposition.  Do not push down strongly on the engine hood. Depending on how strongly or whereyou push down, you could create a dent in the vehicle body.

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”.

Engine Oil is recommended for optimum fueleconomy and cold weather starting. If Mitsubishi Motors Genuine 0W-20 Syn- thetic Engine Oil is not available, 5W-20grade oils displaying th
e ILSAC certification
can be used. However, Mitsubishi Motors Genuine 0W-20Synthetic Engine Oil s
hould be used at the
next oil change to maintain optimum fuel economy and cold weather starting. The oil filter should be replaced at the time or mileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”. Only use high quality
replacement filters on
this vehicle. The manufacturer’s specifica-tions for Genuine Mitsubishi oil filters
require that the filter can withstand a pressure of 256 psi (1.8 MPa). A Genuine Mitsubishioil filter is the best replacement filter. Follow the installation instructions printed on the filter.

The engine coolant reservoir (A) lets youquickly see when you need to add coolant.When the engine is cold
, the level of the cool-
ant in the reservoir should be between the “F” (FULL) and “L” (LOW) marks. The radiatorusually stays full so there is no reason to remove the radiator cap (B) except when you check the coolant freeze point or replace theantifreeze coolant.
Mitsubishi Motors Genuine Coolant provides excellent protection
against corrosion and
rust formation on all me
tals, including alumi-
num, and prevents clogs in some parts of theengine. If you need to add coolant often, or if the level in the reservoir does not drop when theengine cools, the c
ooling system should be
pressure-tested for leaks. Take your vehicle to an authorized Mitsubishi Motors dealer or arepair facility of your
choice for testing.

The radiator cap must be
sealed tight to pre-
vent losing coolant, which may result in engine damage. Only use a Genuine Mitsubishi Parts radiator
cap, or an approved
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.

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.

Check the washer fluid
level at regular inter-
vals and add washer fluid to reservoir if nec-essary. Open the reservoir cap and check the level of washer fluid.Full level is approximately 2 inches (5 cm) below from the upper surface of the reservoir. When freezing weather is anticipated, flush out the water in the reservoir by operating the pump. Fill the reservoir with windshield anti-freeze (not radiator an
tifreeze), and operate
the system for a few seconds to flush out the residual water.

The fluid level must be between the “MAX”and “MIN” marks on the reservoir. The fluid level falls slightly with wear of the brake pads, but this
does not indicate any
abnormality. The fluid in the master cylinder should be checked when doing other work under theengine hood. The brake system should also be checked for leaks at the same time. If the fluid level falls
noticeably in a short
length of time, it indi
cates leaks from the
brake system.
If this occurs, have the vehicle checked by an authorized Mitsubishi Motors dealer or arepair facility of your choice. Use the brake fluid conforming to DOT 3 or DOT 4. The reservoir cap must be tightly sealed to keep dirt and water out.
