7Service precautions
N00937300299
Taking regular care of your vehicle will preserve its value and
appearance as long as possible.
You can do some of the maintenance work yourself, and the
rest should only be performed by an authorized Mitsubishi
Motors dealer or a repair facility of your choice.
If you discover a malfunction or other problem, have it cor-
rected by an authorized Mitsubishi Motors dealer or a repair
facility of your choice.
This section describes the maintenance inspections that you
can do yourself, if you so desire. Follow the instructions and
precautions for each procedure.
Have you purchased the Mitsubishi Motors Diamond Care Pro-
tection Plan? The Plan supplements your new vehicle warran-
ties. See your authorized Mitsubishi Motors dealer for details.
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 to cool down.
If you need to work in the engine compartment with
the engine running, be especially careful that your
clothing, hair, etc. does not get caught in the fan,
drive belts, or other moving parts.
The fan can turn on automatically even if the engine
is not running. Turn the ignition switch to the
“LOCK” position to be safe while you work in the
engine compartment.
Do not smoke or allow open flames around fuel or
the battery. The fumes are flammable.

Be extremely careful when working around the bat-
tery. It contains poisonous and corrosive sulfuric
acid.
Do not get under your vehicle while it is on a jack.
Always use properly rated automotive jack stands.
Handling your vehicle’s parts and materials in the
wrong way can injure you. Ask an authorized
Mitsubishi Motors dealer or a repair facility of your
choice if you have questions.

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.

7Engine hood
N00937500510
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
!
To avoid the risk of being burned, do not touch the
air outlets (A) and air scoop (B) on the engine hood
when the engine compartment 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.

If you drive with the engine hood left open, warning dis-
play is displayed on the information screen in the multi-
information 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.

Engine oil and oil filter
N00937700899
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.

2- Air cleaner filter
3- Brake fluid/Clutch fluid reservoir (if so equipped)
4- Engine coolant reservoir

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”.Engine oil identification markMitsubishi Motors recommends using only engine oils with the
ILSAC certification symbol on the front of the container.
CAUTION
!
Overfilling the crankcase will cause oil aeration and
loss of oil pressure, which could damage the engine.
Engine oil must be properly maintained to avoid
engine and/or turbocharger damage. To better pro-
tect your engine and turbocharger, use fully syn-
thetic 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.

If you cannot find oils with the ILSAC certification symbol,
use an API classification SN 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.
Recommended engine oil viscosity
N00955000096
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.NOTE
Select engine oil of the proper SAE viscosity number
according to the atmospheric temperature.
