Turn the temperature control dial clockwise to make the air
warmer. Turn it counterclockwise to make the air cooler.
NOTE
While the engine coolant temperature is low, the tempera-
ture of the air from the heater will be cool/cold until the
engine warms up, even if you have selected warm air with
the dial.

NOTE
When the “ ” or “ ” position is selected, you cannot
turn the air conditioning off or select the recirculation
position.
This prevents the windows from fogging up.

When the mode selection dial or the blower speed selec-
tion dial is set to the “AUTO” position again after manual
operation, the air selection switch will also be automati-
cally controlled.

When the coolant temperature rises above a certain point,
the air selection is automatically switched to the recircula-
tion position and the indicator light (A) turns on. When
this occurs, the system will not switch to the outside air
position until the coolant temperature goes down, even if
the selection switch is pushed.
Air conditioning switch

Push the switch, and the air conditioning compressor will turn
on. The air conditioning indicator light (A) will come on.
Push the switch again and the air conditioning compressor will
stop and the air conditioning indicator light (A) goes off.
CAUTION
!
Using recirculated air for a long time may cause the
windows to fog up.
CAUTION
!
Using the air conditioning slightly increases the
engine idle speed. Therefore, make sure your foot is
firmly on the brake pedal when shifting the tran-
saxle into drive.

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.

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.

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.
