If the temperature inside the engine compartment is high,
the cooling fans (A) will continue to operate for some
time even if the engine is stopped.
Therefore, the operation sound of the cooling fans may be
heard even after the engine is stopped. This sound is nor-
mal and does not indicate a malfunction.
After operating for a period of time, the cooling fans will
stop automatically.

CAUTION
!
Do not run the engine at high speeds (for example,
by revving it or by accelerating rapidly) immedi-
ately after starting it.
Do not stop the engine immediately after high-speed
or uphill driving. First allow the engine to idle to
give the turbocharger a chance to cool down.
Engine oil must be properly maintained to avoid
engine and/or turbocharger damage. To better pro-
tect your engine and turbocharger, use fully syn-
thetic engine oil.

5Important air conditioning operating tips
N00733700280
1. Park the vehicle in the shade whenever possible. Parking
in the hot sun makes the vehicle interior extremely hot
which then requires more time to cool. If it is necessary to
park in the sun, open the windows for the first few min-
utes of air conditioning to expel the hot air.
2. Afterwards, keep the windows closed when the air condi-
tioning is in use. The entry of outside air through open
windows will reduce cooling efficiency.
3. When running the air conditioning, make sure the air
intake, which is located in front of the windshield, is free
of obstructions such as leaves. Leaves collected in the air-
intake chamber may reduce air flow and plug the water
drains.Air conditioning system refrigerant and lubri-
cant recommendationsIf the air conditioning seems less effective than usual, the cause
might be a refrigerant leak.
Have the system inspected by your authorized Mitsubishi
Motors dealer or a repair facility of your choice.
During a long period of disuseThe air conditioning should be operated for at least five min-
utes each week, even in cold weather. This includes the quick
defrosting mode. Operating the air condition system weekly
maintains lubrication of the compressor internal parts to keep
the air conditioning in the best operating condition.
CAUTION
!
The air conditioning system in your vehicle must be
charged with the refrigerant HFC-134a and the
lubricant SUN-PAG56.
Use of any other refrigerant or lubricant will cause
severe damage and may require replacing your vehi-
cle’s entire air conditioning system.
The release of refrigerant into the atmosphere is not
recommended.
The new refrigerant HFC-134a in your vehicle is
designed not to harm the earth’s ozone layer. How-
ever, it may contribute slightly to global warming.
It is recommended that the old refrigerant be saved
and recycled for future use.

5. Connect one end of one jumper cable to the positive (+)
terminal of the joint terminal, and the other end to the pos-
itive (+) terminal of the booster battery.NOTE
Open the joint terminal cover before connecting the
jumper cable to the positive terminal of the joint terminal.

Use the proper cables suitable for the battery size.
Otherwise heat damage to the cables could result.

Check the jumper cables for damage and corrosion before
use.6. Connect one end of the other jumper cable to the negative
(-) terminal of the booster battery, and the other end to the
engine block of the vehicle with the low battery.
7. Start the engine in the vehicle providing the boost. Let the
engine idle a few minutes, then start the engine in the
vehicle with the low battery.

the batteries, of: →→→.
Make sure that the connection is made to the
engine properly. If the connection is directly made to
the negative side of the battery, the flammable gases
from inside the battery might catch fire and explode,
causing personal injury.
When connecting the jumper cable, do not connect
the positive (+) cable to the negative (-) terminal.
Otherwise sparks can make the battery explode.
CAUTION
!
Make sure that the jumper cable will not be caught
in the cooling fans or other moving parts in the
engine compartment.

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.

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.
