To closeUnlatch the prop from the engine hood and put it back in its
retainer.
Slowly lower the engine hood about 12 inches (30 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.
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.

Engine oil and oil filter
N00937700639
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.

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.


To avoid engine and/or turbocharger damage, use
only fully synthetic engine oil for this vehicle. DO
NOT use conventional petroleum based motor oil or
“blends” of conventional oil and synthetic oil.
Refer to 7-9.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 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.
Recommended engine oil viscosity
N00955000054
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.NOTE

DO NOT use conventional petroleum based motor oil.
Using conventional motor oil may cause engine or turbo-
charger damage.


DO NOT used “blends” of conventional oil and synthetic
oil.


Use ONLY fully synthetic engine oils displaying ILSAC
certification symbol or conforming to the API classifica-
tion SM or higher. If the correct oil is not used, any oil-
related engine or turbocharger failure, along with any
peripheral engine or powertrain damage, will not be cov-
ered by your vehicle warranty.

To replace the oil filter
N00955100013
The oil filter should be replaced at the time or mileage speci-
fied in the “WARRANTY AND MAINTENANCE MAN-
UAL”.
Only use high quality replacement filters on this vehicle. The
manufacturer’s specifications for Genuine Mitsubishi oil filters
require that the filter can withstand a pressure of 256 psi
(1.8 MPa). A Genuine Mitsubishi oil filter is the best replace-
ment filter.
Follow the installation instructions printed on the filter.
Engine coolant
N00937800438
To check the coolant level The coolant reserve tank (A) lets you quickly see when you
need to add coolant. When the engine is cold, the level in the
reserve tank should be between the “FULL” and “LOW”
marks. The radiator usually stays full so there is no reason to
remove the radiator cap (B) except when you check the coolant
freeze point or replace the antifreeze coolant.

To add coolant Use Mitsubishi Genuine Coolant or an equivalent.
Mitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum, and prevents blockages in the radiator, heater, cyl-
inder head, engine block, etc.
If you need to add coolant often, or if the level in the reserve
tank does not drop when the engine cools, the cooling system
should be pressure-tested for leaks. Take your vehicle to an
authorized Mitsubishi Motors dealer or a repair facility of your
choice for testing.
Radiator capThe radiator cap must be tight sealed to prevent losing coolant
which may result in engine damage. Only use a Genuine Mit-
subishi Parts radiator cap, or an approved equivalent.Points to remember

Do not overfill the reserve tank.


Your vehicle uses a special radiator cap that stays sealed
and lets the coolant flow from the reserve tank back to the
radiator when the engine cools down. If you need to
change the cap, use the exact same kind.


Check the coolant freeze point in the radiator with the
proper gauge, and only when it is safe. If you add anti-
freeze, the contents of the reserve tank must be protected
against freezing.


Keep the front of the radiator and condenser clean.
CAUTION
!

Do not use alcohol or methanol antifreeze or any
engine coolants that contain them. Using the wrong
antifreeze can corrode aluminum parts.


When you need to add coolant to the reserve tank,
use at least a 50 % concentration of ethylene-glycol
antifreeze in water. Do not overfill. Use a higher con-
centration (not over 60 %) when the outside temper-
ature is -31 °F (-35 °C) or lower. When the engine is
working very hard (for example, during mountain
driving and/or when the outside temperature is
high), use a 50 % concentration. You can check the
concentration level with a gauge from an automotive
supply store, or your authorized Mitsubishi Motors
dealer or service station can check it for you. Use
only high quality ethylene-glycol antifreeze coolant
that is made to prevent corrosion of all cooling sys-
tem metals.


Do not top off the tank with plain water only. Water
by itself boils at a lower temperature and does not
stop rust or freezing. If the water freezes, it will
damage your cooling system. Do not use tapwater. It
can cause corrosion and rust. WA R N I N G
!

Wait for the engine to cool down before opening the
radiator cap. Otherwise hot steam or boiling coolant
could spray up from the radiator and scald you. CAUTION

If the temperature of the engine coolant does not rise after
the engine is warmed-up, take your vehicle to an autho-
rized Mitsubishi Motors dealer or a repair facility of your
choice to have the thermostat checked, and replaced if
necessary.
Air cleaner filter
N00937900309
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”.
1. Unclamp and take out the air cleaner filter.

The windshield washer fluid reservoir is in the trunk.
Check the washer fluid level at regular intervals and add
washer fluid to reservoir if necessary. NOTE

Do not spill the fluid onto the trunk. If the fluid spilled,
wipe it up immediately.
During cold weatherWhen freezing weather is anticipated, flush out the water in the
reservoir by operating the pump. Fill the reservoir with wind-
shield antifreeze (not radiator antifreeze), and operate the sys-
tem for a few seconds to flush out the residual water.
Brake fluid/Clutch fluid
(if so equipped)
N00938700232
The brake fluid and the clutch fluid share the reservoir tank.To check the fluid levelThe 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 the engine hood. The brake system should
also be checked for leaks at the same time.
If the fluid level falls markedly in a short length of time, it indi-
cates leaks from the brake system.
If this occurs, have the vehicle checked by an authorized Mit-
subishi Motors dealer or a repair facility of your choice.
