Air selection switch
N00736800367
Normally, use the outside air position to keep the windshield
and side windows clear and to quickly remove fog or frost
from the windshield.
To change the air selection, simply press the air selection
switch. A sound will be made every time you push the switch.

Outside air {Indicator light (A) OFF}

Recirculated air {Indicator light (A) ON}
When the air conditioning turns on, the air selection is con-
trolled automatically.
When the air conditioning turns off, the air selection automati-
cally goes back to the outside air position.
The air selection indicator light (A) shows the selected posi-
tion.
NOTE
When the air conditioning operates with the air selection
switch (A) in the outside air position, the system automat-
ically determines whether to continue using outside air or
to perform recirculation.
If the outside temperature is high, the system selects recir-
culation to achieve rapid cooling and causes the air selec-
tion indicator in the switch to illuminate. When the air
conditioning turns off or the blower speed selection dial is
set to the “OFF” position, the air selection automatically
goes back to the outside position.
If the outside air is dusty or contaminated in some way, use the
recirculation position. Switch to the outside air position every
now and then to keep the windows from fogging up.
CAUTION
!
Using recirculated air for a long time may cause the
windows to fog up.

5 Important 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.

If your vehicle has anti-lock brakesIf you drive your vehicle with a low battery charge, after the
engine has been started by using jumper cables, the engine may
misfire. This can cause the anti-lock braking system warning
light to blink on and off. This is only due to the low battery
voltage. It is not a problem with the brake system. If this hap-
pens, fully charge the battery and ensure the charging system is
operating properly.
Engine overheating
N00836500323
When the engine has overheated, the information screen in the
multi-information display will be interrupted and the engine
coolant temperature warning display will appear. The screen
will then change to the engine coolant temperature display
screen and “ ” will flash. 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.
WARNING
!
To avoid personal injury, keep hands, hair, jewelry
and clothes away from the cooling fan. The cooling
fan can start at any time.

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.

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.

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.
WARNING
!
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.

To check the battery indicator
N00901400039
To see the charge of only one cell, check the indicator (A) on
top of the battery. If the indicator is blue when looking from
above, that cell is okay suggesting the battery is okay. This is
not conclusive and 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. If it is white,
that cell is low on charge and the battery may only need charg-
ing.
CAUTION
!
Be sure to install the battery upper cover. Other-
wise, the battery electrolyte may spill and cause a
malfunction.
When installing the battery upper cover, plastic
nuts, and air duct, do not touch the cooling fan or
other moving parts in the engine compartment. Be
especially careful that the cables, your clothing or
hair, etc., do not get caught in the cooling fan or
other moving parts.
