NOTEWhile 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.
When the temperature is set to the highest or the lowest
setting under the AUTO operation, the air selection and
the air conditioning will be automatically changed as fol-
lows.
Also, if the air selection is operated manually after an
automatic changeover, manual operation will be selected.

Operating the air conditioning system (automatic 
mode)
N00731700332
In normal conditions, use the system in the AUTO mode and
follow these procedures:
1. Set the blower speed selection dial to the “AUTO” posi-
tion.
2. Select the temperature control dial to the desired tempera-
ture. The temperature can be set within a range of around
61 to 89. The temperature will increase as the dial is
turned to the right.
3. Set the mode selection dial to the “AUTO” position.
The vents (except between “ ” and “ ”), recirculation/out-
side air, blower speed, and ON/OFF of air conditioning will be
controlled automatically.
NOTESet the temperature at about 75 under normal conditions.
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. To prevent the windshield and windows from
fogging up, the vent mode will be changed to “ ” or
“ ” and the blower speed will be reduced.

6Engine overheating
N00836500033
When the engine is overheating, the information screen in the
multi-information display will be interrupted and the engine
coolant temperature warning display will appear. Also “ ”
will blink. 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 fans 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 bar graph for the
engine coolant temperature warning display on the multi-
information display goes down. When it is in the middle
of the normal zone, you can start driving again. If the bar
graph stays in the red zone, turn off the engine.
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.
WA R N I N G
!To avoid personal injury, keep hands, hair, jewelry
and clothes away from the cooling fans. The cooling
fans 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.

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
engine coolant temperature display on the multi-informa-
tion display. You can start driving again when the bar
graph for the engine coolant temperature display 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.

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.

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
N00937800500
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 Genuine Coolant provides excellent protection
against corrosion and rust formation on all metals, including
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. 
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. 
Use “Dia Queen Super Long Life Coolant Premium” or equiva-
lent*.
*: 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. 
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. 
CAUTION
