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.

7Engine hood
N00937500464
To openUse the engine hood release lever (located under the instrument
panel near the driver’s door) to unlock the engine hood.
Pull the lever toward you to release the engine hood latch.
CAUTION
!
For vehicles with turbocharger, to avoid the risk of
being burned, do not touch the air outlet (A) and air
scoop (B) on the engine hood when the engine com-
partment is hot (when the engine is running or
immediately after the vehicle has been driven).
WA R N I N G
!
Never use the release lever to unlatch the engine
hood while the vehicle is in motion.
Do not drive your vehicle unless the engine hood is
locked.

Release the safety lever and lift the engine hood. NOTE
To prevent damage to the engine hood and wipers, make
sure the wipers are at resting position when you open the
engine hood. Support the engine hood with the hood prop. Insert the hood
prop securely in the opening under the hood marked with an
arrow.
CAUTION
!
Always insert the support prop into the hole spe-
cially made for it. Propping the engine hood at any
other place could cause the prop to slip out and lead
to an accident.
The hood prop can fall out if the hood is lifted by a
strong wind.

To closeUnlatch the prop from the engine hood and put it back in its
retainer.
Slowly lower the engine hood about 8 inches (20 cm), then let
it drop from its own weight.
NOTE
If this does not close the engine hood properly, drop it
again from a slightly higher position.

Do not push down strongly on the engine hood. Depend-
ing on how strongly or where you push down, you could
create a dent in the vehicle body.

For vehicles equipped with the theft-alarm system, if you
drive with the engine hood left open, warning display is
displayed on the information screen in the multi-informa-
tion display.
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 completely
closed, it could open up while driving.

7Engine oil and oil filter
N00937700860
To check and refill engine oil It is normal for an engine to use oil. You may need to add oil
between 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 insert it all the way into the crankcase. Slowly remove it
again. The oil level must not go above the line on the dipstick.
If the level does not reach the line, which shows the smallest
amount of oil required, remove the oil filler cap on the engine
valve cover, and fill to within the “Good” range. Except for vehicles with turbocharger

Vehicles with turbocharger

NOTE
Engine oil consumption is greatly influenced by payload,
engine speed, etc.

The engine oil will deteriorate rapidly if the vehicle is
subjected 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 MAINTENANCE MANUAL”.
CAUTION
!
Overfilling the crankcase will cause oil aeration and
loss of oil pressure, which could damage the engine.
For vehicles with turbocharger, engine oil must be
properly maintained to avoid engine and/or turbo-
charger damage. To better protect your engine and
turbocharger, use fully synthetic engine oil.

WA R N I N G
!
Used engine oil is poisonous, and can damage your
skin. Prolonged and repeated contact may cause
serious skin disorders, including dermatitis and can-
cer. Don’t let used oil touch your skin. Wash thor-
oughly after working with it.
Keep used oil out of the reach of children.

Engine oil identification markMitsubishi Motors recommends using only engine oils with the
ILSAC certification symbol on the front of the container.If you cannot find oils with the ILSAC certification symbol,
use an API classification SM or higher oil with the following
label.
This mark appears on the top of the oil container and tells you
two important things about the oil.ILSAC certification symbol
1- The top portion shows the quality of the oil.
2- The center portion shows the SAE grade of the oil viscosity.API service symbol
