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.
Air cleaner filter
N00937900165
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”. 2.4 liter modelsUnclamp and take out the air cleaner filter.
After replacing the air cleaner filter, put the cover back on in its
original position. 3.8 liter models1. Loosen the bolt of the resonator using a screwdriver.
2. Remove the resonator.

!
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.

3. Unclamp and take out the air cleaner filter.
After replacing the air cleaner filter, install the resonator by fol-
lowing the removal steps in reverse. Fit the resonator with
careful reference to the alignment position (A), and securely
tighten the bolt.NOTE
Genuine Mitsubishi Motors Parts are recommended when
replacing the air cleaner filter.
Automatic transaxle fluid
(if so equipped)
N00938000512
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
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.

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.
Fluid typeUse only “DIAMOND ATF SP III” transaxle fluid to ensure
optimum transaxle performance. Special additives Mitsubishi Motors Corporation does not recommend the addi-
tion of any fluid additives to the transaxle.

Transaxle fluid is extremely flammable and poison-
ous. Do not spill fluid when adding or draining.

The windshield and rear window washer (ECLIPSE only) fluid
reservoir is in the engine compartment.
Check the washer fluid level at regular intervals and add
washer fluid to reservoir if necessary. During cold weatherWhen freezing weather is anticipated, flush out the water in the
reservoir by operating the pump. Fill the reservoir with
windshield antifreeze (not radiator antifreeze), and operate the
system for a few seconds to flush out the residual water.

7 Brake fluid/Clutch fluid
(if so equipped)
N00938700229
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 is monitored by a float. When the brake fluid
level falls below the “MIN” mark, the brake fluid warning
lamp lights up.
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
Mitsubishi Motors dealer or a repair facility of your choice.
Fluid typeUse the brake fluid conforming to DOT 3 or DOT 4. The reser-
voir cap must be tightly sealed to keep dirt and water out.
CAUTION
!
Do not let any petroleum-based fluid touch, mix
with, or get into the brake fluid. This will damage
the seals.
Be careful when handling brake fluid. It can damage
painted surfaces.
Use only the listed brake fluid. Different brands of
brake fluid have different additives, and these can
cause a chemical reaction. Do not mix brands of
brake fluid.
Keep the reservoir tank cap closed to keep the brake
fluid from evaporating.

7Power steering fluid
N00939000333
To check the fluid levelCheck the fluid level in the reservoir while the engine is idling.
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
N00939100318
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.
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.

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.

NOTE
Check each battery terminal for corrosion. You can stop
more corrosion by washing with a solution of baking soda
and water. Grease the posts and clamps after cleaning or
tightening them.

Check to see that the battery is securely installed and can-
not be moved. Also check each terminal for tightness.

If you will not be driving your vehicle for a long period of
time, remove the battery and store it in a place where the
battery fluid will not freeze. The battery only should be
stored with a full charge.
WA R N I N G
!
Never disconnect the battery while the engine is run-
ning, or you could damage the vehicle’s electrical
parts.
Never short-circuit the battery. This could cause it
to overheat and be damaged.
Keep sparks, cigarettes, and flames away from the
battery because the battery could explode.
Electrolyte (battery acid) is made of corrosive
diluted sulfuric acid. If it spills on nearby parts, it
can crack, stain, or discolor them. And if gets on
your skin or in your eyes, it can cause burns or
blindness. Please observe the following handling
instructions:
• If electrolyte gets on plastic parts or other nearby
parts, wipe it off with a soft cloth or chamois
soaked in a solution of water and neutral detergent
then immediately rinse the affected parts with
plenty of water.
• If electrolyte gets on your hands or clothes, rinse
thoroughly with water. If electrolyte gets in your
eyes, flush them with water immediately and get
immediate medical attention.

Open doors and windows in any closed space where
you may be charging or working with the battery.
Always wear protective clothing and goggles when
working with the battery, or have a skilled automo-
bile technician do it.
If you are quick-charging your battery, first discon-
nect the battery cables.

In order to prevent a short circuit, be sure to discon-
nect the negative (-) terminal first, and reconnect it
last.
If the electrolyte level is very low, have the battery
checked at an authorized Mitsubishi Motors dealer
or a repair facility of your choice.
Battery terminals and related accessories contain
lead and lead compounds. Wash hands after han-
dling.
