NOTEEngine 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.
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 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 viscosityUse engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.
SAE 5W-20 engine oil is strongly recommended for optimum
fuel economy and cold starting.

To replace the oil filterThe 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
N00937800395
To check the coolant level The coolant reserve system provides a quick visual method for
determining the coolant level. When the engine is cold, the
level of the coolant in the reserve tank should be between the
“F” (FULL) and “L” (LOW) marks. The radiator normally
remains completely full so there is no need to remove the radi-
ator cap except for checking the coolant freeze point or replac-
ing the antifreeze coolant.
CAUTION
!Take care not to bend the oil filter cover when
replacing the oil filter.

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.

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
N00937900295
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”.
Unclamp and take out the air cleaner filter.
After replacing the air cleaner filter, put the cover back on in its
original position. NOTEGenuine Mitsubishi Parts are recommended when replac-
ing the air cleaner filter.
CAUTION
!Take care not to scratch the engine air flow sensor
when removing the air cleaner cover.

7Automatic transaxle fluid
N00938000453
The automatic transaxle should be maintained and serviced by
an authorized Mitsubishi Motors dealer or a repair facility of
your choice to obtain the best performance and longest life. It
is important that the transaxle fluid is kept at the correct level. To check the fluid level The fluid level should be checked when the engine temperature
gauge shows the engine is warmed up and the fluid in the tran-
saxle is heated to its normal working temperature. Driving with
the wrong fluid level will rapidly wear out the transaxle and
destroy the fluid.
Procedure for checking the fluid level 1. With the brake pedal fully depressed and the engine
idling, select each gear momentarily, ending with the
selector lever in the “P” (PARK) position.
2. The fluid level should be at the HOT mark, but never
above the HOT mark when the engine is warmed up. Add
or drain fluid to get to the correct level.
3. Make certain that the dipstick cap is installed properly to
keep dirt and water out of the transaxle.
WA R N I N G
!Transaxle fluid is extremely flammable and poison-
ous. Do not spill fluid when adding or draining.
