Engine Oil is recommended for optimum fueleconomy and cold weather starting. If Mitsubishi Motors Genuine 0W-20 Syn- thetic Engine Oil is not available, 5W-20grade oils displaying th
e ILSAC certification
can be used. However, Mitsubishi Motors Genuine 0W-20Synthetic Engine Oil s
hould be used at the
next oil change to maintain optimum fuel economy and cold weather starting. The oil filter should be replaced at the time or mileage specified in the “WARRANTY ANDMAINTENANCE MANUAL”. Only use high quality
replacement filters on
this vehicle. The manufacturer’s specifica-tions for Mitsubishi Mo
tors Genuine oil fil-
ters require that the filter can withstand a pressure of 256 psi (1.8 MPa). A MitsubishiMotors Genuine oil filter
is the best replace-
ment filter. Follow the installation instructions printed onthe filter.

The engine coolant reservoir (A) lets youquickly see when you need to add coolant. When the engine is cold
, the level of the cool-
ant in the reservoir should be between the “F”(FULL) and “L” (LOW) marks. The radiator usually stays full so there is no reason to remove the radiator cap (B) except when youcheck the coolant freeze point or replace the antifreeze coolant.
Mitsubishi Motors Genuine Coolant provides excellent protection
against corrosion and
rust formation on all me
tals, including alumi-
num, and prevents clogs in some parts of theengine. If you need to add coolant often, or if the level in the reservoir does not drop when theengine cools, the c
ooling system should be
pressure-tested for leaks. Take your vehicle to an authorized Mitsubishi Motors dealer or arepair facility of your
choice for testing.

The radiator cap must be
sealed tight to pre-
vent losing coolant, which may result in engine damage. Only use a Mitsubishi Motors Genuine Parts radiator cap, or anapproved equivalent.
 Do not overfill the reservoir.  Your vehicle uses a special radiator cap that stays sealed and lets the coolant flow from the reservoir back to the radiatorwhen the engine cools down. If you need to change the cap, use the exact same kind.
 Check the coolant freeze point in the radi- ator with the proper gauge, and only whenit is safe. If you add antifreeze, the con- tents of the reservoi
r must be protected
against freezing. Keep the front of the radiator and con- denser clean.  If the engine coolan
t temperature does not
rise after the engine
is warmed-up, take
your vehicle to an au
thorized Mitsubishi
Motors dealer or a repair facility of your choice to have the thermostat checked, and replaced if necessary.

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”.
 The required concentrati
on of anti-freeze dif-
fers depending on the
expected ambient tem-
perature.Above -31 °F (-35 °C) : 50 % concentration of anti-freeze Below -31 °F (-35 °C) : 60 % concentrationof anti-freeze You can check the concentration level with a gauge from an automotive supply store, oryour authorized Mitsubi
shi Motors dealer or
service station can check it for you. Do not use water to adjust the concentration of coolant. Do not top off the reservoir with plain water only. Water by itself bo
ils at a lower temper-
ature and does not stop rust or freezing. If thewater freezes, it will
damage your cooling
system. Do not use tapwater. It can cause corrosion and rust.
Radiator cap
CAUTION
WA R N I N G Wait for the engine to cool down before opening the radiator
cap. Otherwise hot
steam or boiling c
oolant could spray up
from the filler po
rt and scald you.

Check the washer fluid
level at regular inter-
vals and add washer fluid to reservoir if nec-essary. Open the reservoir cap and check the level of washer fluid.Full level is approximately 2 inches (5 cm) below from the upper surface of the reservoir. When freezing weather is anticipated, flush out the water in the reservoir by operating the pump. Fill the reservoir with windshield anti-freeze (not radiator an
tifreeze), and operate
the system for a few seconds to flush out the residual water.
N00938701314
The 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 theengine hood. The brake system should also be checked for leaks at the same time. If the fluid level falls
noticeably in a short
length of time, it indi
cates leaks from the
brake system.
If this occurs, have the vehicle checked by an authorized Mitsubishi Motors dealer or arepair facility of your choice. Use the brake fluid conforming to DOT 3 or DOT 4. The reservoir cap must be tightly sealed to keep dirt and water out.

The battery is weaker in cold temperatures. This has to do with its chemical and physical properties and is why a very cold battery, especially one with a lo
w charge, will have a
hard time starting your vehicle. It is recommended that you have your battery and charging system checked by an autho-rized Mitsubishi Motors dealer or a repair
facility of your choice
before the start of cold
weather. If necessary, have it charged. Thiswill provide more reliab
le starting, and longer
battery life.
