6Engine overheating
N00836500222
If the engine coolant temperature gauge indicator moves to the
“H” (hot) position (red zone), the engine may be overheated. If
this happens:
1. Stop the vehicle in a safe place. Turn on the hazard warn-
ing flashers.
2. With the engine still running, carefully raise the engine
hood to vent the engine compartment.
3. Check that the cooling fan is running. If the fan is not
turning, stop the engine immediately and contact an
authorized Mitsubishi Motors dealer or a repair facility of
your choice for assistance.
4. If you see steam or spray coming from under the hood,
turn off the engine.5. If you do not see steam or spray coming from under the
hood, leave the engine on until the temperature indicator
on the instrument panel moves below the red zone. When
it is in the middle of the normal zone, you can start driving
again. If the indicator stays in the red zone, turn off the
engine.
WA R N I N G
!
To avoid personal injury, keep hands, hair, jewelry
and clothes away from the cooling fan. The cooling
fan can start at any time.
WA R N I N G
!
Before raising the engine hood, check to see if there
is steam or spray coming from under the hood.
Steam or spray coming from an overheated engine
could seriously scald you.
Do not open the hood until there is no steam or
spray.

6. When you do not see any more steam or spray, open the
hood. Look for obvious leaks, such as a split radiator
hose. Be careful as components will be hot. Any leak
source must be repaired.
7. If there is no obvious leak source, check the coolant level
in the reserve tank. If there is none, or if it is too low,
slowly add coolant.
8. If the reserve tank needs coolant, you will probably also
need to add coolant to the radiator. Do not loosen or
remove the radiator cap until the engine has cooled down.9. Start the engine, and slowly add coolant, up to the bottom
of the filler neck. Use plain water if you have to (and
replace it with the right coolant as soon as possible).
10. Replace the radiator cap and tighten it fully. Check the
temperature indicator. You can drive when the indicator
returns to the normal zone.
11. Have your vehicle checked by your authorized Mitsubishi
Motors dealer or a repair facility of your choice.
WA R N I N G

Removing the radiator cap could scald you with
escaping hot water or steam. When checking the
radiator level, cover the cap with a cloth before try-
ing to remove it. Turn it slowly counterclockwise,
without pressing down, to the first notch. The pres-
sure in the system will then be let out. When the
pressure is COMPLETELY LET OUT, press down
and keep turning the cap counterclockwise until it
will come off.

7Service precautions
N00937300156
Taking regular care of your vehicle will preserve its value and
appearance as long as possible.
You can do some of the maintenance work yourself, and the
rest should only be performed by an authorized Mitsubishi
Motors dealer or a repair facility of your choice.
If you discover a malfunction or other problem, have it cor-
rected by an authorized Mitsubishi Motors dealer or a repair
facility of your choice.
This section describes the maintenance inspections that you
can do yourself, if you so desire. Follow the instructions and
precautions for each procedure.
Have you purchased the Mitsubishi Motors Diamond Care Pro-
tection Plan? The Plan supplements your new vehicle warran-
ties. See your authorized Mitsubishi Motors dealer for details.
WA R N I N G
!
When checking or servicing the inside of the engine
compartment, be sure the engine is stopped and has
had a chance to cool down.
If you need to work in the engine compartment with
the engine running, be especially careful that your
clothing, hair, etc. does not get caught in the fan,
drive belts, or other moving parts.
The fan can turn on automatically even if the engine
is not running. Turn the ignition key to the “LOCK”
position and remove the key to be safe while you
work in the engine compartment.
Do not smoke or allow open flames around fuel or
the battery. The fumes are flammable.

Be extremely careful when working around the bat-
tery. It contains poisonous and corrosive sulfuric
acid.
Do not get under your vehicle while it is on a jack.
Always use properly rated automotive jack stands.
Handling your vehicle’s parts and materials in the
wrong way can injure you. Ask an authorized Mit-
subishi Motors dealer or a repair facility of your
choice if you have questions.

7 Engine oil and oil filter
N00937700772
To check and refill engine oil It is normal for an engine to use oil. You may need to add oil
between the recommended oil change intervals. Before starting
the engine, check the engine oil level. Refill if necessary.
To check the oil level, remove the dipstick, wipe it off, and
gently insert it all the way into the crankcase. Slowly remove it
again. The oil level must not go above the line on the dipstick.
If the level does not reach the line, which shows the smallest
amount of oil required, remove the oil filler cap on the engine
valve cover, and fill to within the “Good” range. 2.4 liter engine
Good
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.

7Engine coolant
N00937800281
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.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.
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.

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 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.
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.

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 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.
CAUTION
!
Take care not to scratch the engine air flow sensor
when removing the air cleaner cover.
