If you are unable to find oils with the ILSAC certification
mark (ªStarburstº symbol), an API classification SL, SL/CF
oil with the above label.
This mark appears on the top of the oil containers and has
two distinct areas for identifying various aspects of the oil.
1. The top portion will indicate the quality of the oil.
2. The center portion will show the SAE grade of the oil.
Recommended engine oil viscosity
Use engine oil with the proper thickness for the outdoor
temperatures where you will be driving.
SAE 5W-20, SAE 5W-30 and SAE 10W-30 engine oil can
be used in outdoor temperatures ranging from 0 ÉF to 100
ÉF (-18ÉC to 38ÉC). However, for optimum fuel economy
and cold starting, select the low SAE viscosity grade oil
for the expected temperature range. SAE 5W-20 or SAE
5W-30 engine oil is recommended.

ENGINE COOLANT
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 FULL and LOW marks. The
radiator normally remains completely full so there is no
need to remove the radiator cap except for checking the
coolant freeze point or replacing the antifreeze coolant.
To add coolant
Use DaimlerChrysler Genuine Coolant or an equivalent.
Genuine Coolant provides excellent protection against
corrosion and rust formation of all metals, including
aluminum, and prevents clogs in the radiator, heater,
cylinder head, engine block, etc.
If frequent coolant additions are required, or if the level
in the reserve tank does not drop when the engine cools,
the system should be pressure-tested for leaks. Take your
vehicle to an authorized dealer for inspection of the
cooling system.
CAUTION!
²Do not use alcohol or methanol anti-freeze or any
engine coolants mixed with alcohol or methanol
anti-freeze. The use of an improper anti-freeze can
cause corrosion of aluminum components.
²When additional coolant is needed to maintain
the proper level, a minimum of 50% concentration
of ethylene-glycol antifreeze in water should be
added to the reserve tank. Do not overfill. A
higher concentration (not to exceed 60%) should
be used if a lower freezing point is required. The
concentration level can be checked using instru-
ments available at automotive supply stores, or
can be done by your authorized dealer or service
station. Use only high quality ethylene-glycol
antifreeze coolant formulated to prevent corrosion
of all cooling system metals.
²Do not top off with water only. Water by itself
reduces the rust-protective and anti-freeze quali-
ties of the coolant and has a lower boiling point. It
can also cause damage to the cooling system if it
should freeze. Do not use tap water, as it may
cause corrosion and rust formation.

Radiator cap
The radiator cap must be fully tightened to prevent loss
of coolant and engine damage.
WARNING!
Make sure that the engine is thoroughly cooled
down before removing the radiator cap, otherwise
hot steam or boiling coolant may gush from the filler
port and scald you.
Points to remember
1. Do not overfill the reserve tank.
2. A special radiator cap is used to ensure sealing and to
allow the coolant to return from the reserve tank to the
radiator when the engine cools. If cap replacement is
necessary, use the proper cap.
3. Check the coolant freeze point in the radiator using
proper instruments, when it is safe to do so. If antifreeze
is added, the contents of the reserve tank must be
protected against freezing.
4. Keep the front of the radiator clean. Keep the front of
the condenser clean.5. If the temperature of the engine coolant does not rise
normally after engine warm-up, take the vehicle to an
authorized dealer to have the thermostat checked, and
replaced if necessary.
BRAKE FLUID
Recommended brake fluid conforming to DOT 3 or DOT 4
should be used. The reservoir cap must be fully tightened
to avoid contamination from foreign matter or moisture.
CAUTION!
²Do not allow petroleum-based fluid to contact,
mix with, or otherwise contaminate the brake
fluid. Seal damage will result.
²Take care in handling brake fluid as it may cause
damage to painted surfaces.
²Use only the specified brake fluid. Also, the
additives in different brands may result in a
chemical reaction when mixed together, so avoid
mixing different brands if possible.
²Keep the reservoir tank cap closed to prevent the
brake fluid from evaporating or absorbing moisture.

CLUTCH FLUID (MANUAL TRANSAXLE)
To check the clutch fluid
The clutch fluid in the clutch master cylinder should be
checked when performing other underhood services. In
addition, the system should be checked for leakage at the
same time. Check to make certain that the clutch fluid
level is always between the MAX and MIN level mark-
ings on the fluid reservoir and refill the fluid, if necessary.
A rapid fluid loss indicates a leak in the clutch system
which should be inspected by an authorized dealer and
repaired immediately.
To replace the fluid
Recommended brake fluid conforming to DOT 3 or DOT 4
should be used.
The reservoir cap must be fully tightened to avoid contami-
nation from foreign matter or moisture.
CAUTION!
²Do not allow petroleum-based fluid to contact,
mix with, or otherwise contaminate the clutch
fluid. Seal damage will result.
²Take care in handling clutch fluid as it may cause
damage to painted surfaces.
²Use only the specified clutch fluid.
Also, the additives in different brands may result
in a chemical reaction when mixed together, so
avoid mixing different brands if possible.
²Keep the reservoir tank cap closed to prevent the
clutch fluid from deteriorating due to moisture or
air exposure.

BATTERY
The condition of the battery is very important for quick
starting and to keep the vehicle's electrical system work-
ing properly. Check the battery regularly.
If battery performance is suspect, have the battery and
charging system tested by an authorized Mitsubishi
dealer.
NOTE
1. After replacing the battery, the electronic control sys-
tem data for the automatic transaxle, etc., will be erased.
As a result, shifting may be rough.
Shifting will become smoother after several changes in
speed.
2. Memory data for settings made by the user may be
erased when the battery is replaced. If this happens,
establish the settings again using the relevant procedures.
Checking battery electrolyte level
Use the following procedure to check the battery electro-
lyte level.
Open the lid on the battery cover (if so equipped).
NOTE: Be sure to close the battery cover after checking
the battery fluid level and after replacing the battery.

WARNING!
²If the battery goes flat, be sure to check the battery
electrolyte level before connecting booster cables.
²After checking the battery electrolyte level, make
sure the caps are fitted securely.
²If any of the caps has a loose fit, replace the
battery.
During cold weather
The capacity of the battery is reduced at low tempera-
tures. This is the result of its chemical and physical
properties and this is why a very cold battery, particu-
larly one that is not fully charged, will only deliver a
fraction of the starter current that is normally available.
It is recommended that you have the battery checked by
an authorized dealer before the start of cold weather and,
if necessary, have it charged or replaced. This not only
ensures reliable starting, but prolongs battery life.
Disconnection and connection
To disconnect the battery cable, stop the engine, discon-
nect the negative terminal first, then the positive termi-
nal. To reconnect the battery, first connect the positive
terminal and then the negative terminal, before starting
the vehicle.

electrical components.
²Never short-circuit the battery; doing so could
cause it to overheat and be damaged.
²Keep sparks, cigarettes and flames away from the
battery because the battery may produce an explo-
sion.
²Electrolyte (battery acid) is corrosive diluted sul-
furic acid. If electrolyte comes in contact with,
your hands, eyes, clothes, or the coated surface of
your vehicle, thoroughly flush the area with wa-
ter. If electrolyte gets in your eyes, flush them
with water immediately and get prompt medical
attention.
WARNING!
²Ventilate the area when charging or using the
battery in an enclosed space.
²Always wear protective clothing and goggles
when working with the battery, or have a skilled
technician do it.
²If the battery is to be quick-charged, first discon-
nect the battery cables from the vehicle.
²In order to prevent a short circuit, be sure to
disconnect the negative(-) terminal first, and re-
connect it last.
²If the electrolyte level is very low, have the battery
checked at an authorized dealer.
²Battery posts, terminals and related accessories
contain lead and lead compounds. Wash hands
after handling.
