3.0 L modelsSAE 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 replacement
filter.
Follow the installation instructions printed on the filter.

7Engine coolant
N00937800496
To check the coolant levelThe engine coolant reserve tank (A) lets you quickly see when
you need to add coolant. When the engine is cold, the level of
the coolant 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 coolantMitsubishi Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
aluminum, and prevents clogs in some parts of engine.
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.
FULL
LOW
Use “Dia Queen Super Long Life Coolant Premium” or equiva-
lent*.
*: similar high quality ethylene glycol based non-silicate, non-
amine, non-nitrate and non-borate coolant with long life
hybrid organic acid technology
CAUTION
!
Do not use alcohol or methanol antifreeze or any
engine coolants that contain them. Using the wrong
antifreeze can corrode aluminum parts.
The required concentration of anti-freeze differs
depending on the expected ambient temperature.
Above -31 °F (-35 °C) : 50 % concentration of anti-
freeze
Below -31 °F (-35 °C) : 60 % concentration of anti-
freeze
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.

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.
If the engine coolant temperature does not rise after the
engine is warmed-up, take your vehicle to an authorized
Mitsubishi Motors dealer or a repair facility of your
choice to have the thermostat checked, and replaced if
necessary.
Do not use water to adjust the concentration of cool-
ant.
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.

Automatic transaxle fluid
(if so equipped)
N00938000525
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 levelThe fluid level should be checked when the bar graph for the
engine coolant temperature display on the multi-information
display shows the engine is warmed up and the fluid in the
transaxle is heated to its normal working temperature. Driving
with the wrong fluid level will rapidly wear out the transaxle
and destroy the fluid.
CAUTION
!
Take care not to scratch the engine air flow sensor
when removing the air cleaner cover.3.0 L modelsBK0138000US.book 16 ページ ２０１１年４月１３日　水曜日　午前１１時１７分

Procedure for checking the fluid level1. 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.
Fluid typeUse only “DiaQueen ATF-J3” transaxle fluid to ensure opti-
mum transaxle performance.Special additivesMitsubishi Motors Corporation does not recommend the addi-
tion of any fluid additives to the transaxle.
WA R N I N G
!
Transaxle fluid is extremely flammable and poison-
ous. Do not spill fluid when adding or draining.
Good (Hot)
CAUTION
!
Using the improper transaxle fluid may damage the
transaxle.

Whenever the oil level is checked, add oil as necessary to
maintain the proper level.
Fill or change oil according to the table.Fluid type

The windshield and rear window washer fluid reservoir is in
the engine compartment.
Check the washer fluid level at regular intervals and add
washer fluid to reservoir if necessary.
Open the reservoir cap and check the fluid level with the dip-
stick.
When 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.

Check to make certain that the power steering fluid level is
always between the “MAX” and “MIN” level markings on the
fluid reservoir and refill the fluid, if necessary.Fluid type
Battery
N00939100839
The condition of the battery is very important for quick starting
and to keep the vehicle’s electrical system working properly.
Check the battery regularly.
To see the charge of only one cell, check the indicator (A) on
top of the battery. If the indicator is blue when looking from
above, that cell is okay suggesting the battery is okay. This is
not conclusive and if battery performance is suspect, have the
battery and charging system tested by an authorized Mitsubishi
Motors dealer or a repair facility of your choice. If it is white,
that cell is low on charge and the battery may only need charg-
ing.

NOTE
After replacing the battery, the electronic control system
data for the automatic transaxle, etc., will be erased.
As a result, shifting may be rough.
Shifting will become smoother after several changes in
speed.Checking battery electrolyte levelThe electrolyte level must be between the limits shown on the
outside of the battery. Fill it with distilled water as needed. The
inside of the battery is divided into several compartments. Take
the cap off of each compartment and fill to the mark.
Do not fill above the top line because a spill during driving
could cause damage.During cold weatherThe battery is weaker in cold temperatures. This has to do with
its chemical and physical properties and is why a very cold bat-
tery, especially one with a low charge, will have a hard time
starting your vehicle.
It is recommended that you have your battery and charging sys-
tem checked by an authorized Mitsubishi Motors dealer or a
repair facility of your choice before the start of cold weather. If
necessary, have it charged. This will guarantee more reliable
starting, and longer battery life.
Disconnection and connectionTo disconnect the battery cable, stop the engine. Disconnect the
negative (-) terminal first, then the positive (+) terminal. To
reconnect the battery, first connect the positive (+) terminal and
then the negative (-) terminal, before starting the vehicle.NOTE
Open the terminal cover (A) before disconnecting or con-
necting the positive (+) terminal of the battery.

Loosen the nut (B) and then disconnect the battery cable
from the positive (+) terminal.
