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 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.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

Recommended engine oil viscosity
N00955000070
Use engine oil with the proper thickness for the outdoor tem-
peratures where you will be driving.Except for vehicles with turbochargerSAE 0W-20 engine oil is strongly recommended for optimum
fuel economy and cold starting.
If SAE 0W-20 is not available the ILSAC certification oil of
other viscosity grades can be temporarily used.
Vehicles with turbochargerNOTE
Select engine oil of the proper SAE viscosity number
according to the atmospheric temperature.

SAE 0W-30 and 0W-40 engine oil are recommended to
use to improve engine startability on a very cold weather
condition.

To replace the oil filter
N00955100042
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
N00937800542
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 Mitsubishi Motors Genuine Coolant provides excellent protec-
tion against corrosion and rust formation on all metals, includ-
ing aluminum, and prevents blockages 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.

Use “Mitsubishi Motors Genuine Super Long Life Coolant Pre-
mium” or an equivalent*.
* : 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
Mitsubishi 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 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.
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.
