Check the battery, including terminals and cables. During
extremely cold weather, the battery will not be as strong.
Also, the battery power level may drop because more
power is used for cold starting and driving.
Before driving the vehicle, check to see if the engine runs
at the proper speed and if the headlights are as bright as
normally. Charge or replace the battery if necessary. Dur-
ing extreme cold weather, it is possible that a very low
battery could freeze.

Warm the engine sufficiently. After starting the engine,
allow a short warm-up time to distribute oil to all cylin-
ders and turbocharger. Then drive your vehicle slowly.

Stay at low speeds at first so that the transaxle, transfer
case and rear axle oil have time to spread to all the lubri-
cation points.

Manual transaxle can be harder to shift in cold weather
conditions. This is normal and shifting will get easier as
the transaxle warms up.
Check the engine antifreeze.
If there is not enough coolant because of a leak or from
engine overheating, add Dia Queen Super Long Life
Coolant Premium or equivalent.
Please read this section in conjunction with the “Engine
coolant” on page 7-10.

Mitsubishi Motors recommends that the standard equip-
ment tires be replaced with winter tires when the vehicle
is going to be used in winter.
The standard equipment tires provided with this vehicle
are summer tires and use a high-grip compound that pro-
vides superior grip.
The road grip, however, is reduced in winter.
When replacing the standard equipment tires with winter
tires, all four tires must be replaced using radial identical-
size winter tires.

!
The battery gives off explosive hydrogen gas. Any
spark or flame can cause the battery to explode,
which could cause serious injury or death.
Always wear protective clothes and a face mask
when working with your battery, or let a skilled
mechanic do it.

Never open the radiator cap when the radiator is
hot. You could be seriously burned.

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.

Engine oil and oil filter
N00937700639
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
N00955100013
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 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.
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.
