Because of the necessity of this anti-corrosion agent, the cool-
ant must not be replaced with plain water even in summer. The
required concentration of anti-freeze differs depending on the
expected ambient temperature.
Diesel-powered vehiclesThe coolant level in this tank should be kept between the
“LOW” and “FULL” marks when measured while the engine is
cold.

!●Do 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 the aluminium components.●For effective anti-corrosion and anti-freeze per-
formance, keep the anti-freeze concentration within
the range of 30 to 60 %.
Concentrations exceeding 60 % will result in a
reduction of both the anti-freeze and cooling per-
formance thus adversely affecting the engine.●Do not top up with water only.
Water by itself reduces the rust-protective and anti-
freeze qualities of the coolant and has a lower boil-
ing point. It can also cause damage to the cooling
system if it should freeze. Do not use tapwater, as it
can cause corrosion and rust formation.

To add coolantThe cooling system is a closed system and normally the loss of
coolant should be very slight. A noticeable drop in the coolant
level could indicate leakage. If this occurs, we recommend you
to have the system checked as soon as possible.
If the level should drop below the “LOW” level on the reserve
tank, open the lid and add coolant.Anti-freezeThe engine coolant contains an ethylene glycol anti-corrosion
agent. The cylinder head and water pump housing are cast alu-
minium alloy, and periodic changing of the engine coolant is
necessary to prevent corrosion of these parts.
Use only “BASF Glysantin Alu Protect Premium/G30”.
It has excellent protection against corrosion and rust formation
of all metals including aluminium and can avoid clogs in the
radiator, heater, cylinder head, engine block, etc.
Because of the necessity of this anti-corrosion agent, the cool-
ant must not be replaced with plain water even in summer.
The anti-freeze must fill 50 % concentration coolant in all tem-
perature conditions.
During cold weatherIf the temperatures in your area drop below freezing, there is
the danger that the coolant in the engine or radiator could
freeze and cause severe damage to the engine and/or radiator.
Add a sufficient amount of anti-freeze to the coolant to prevent
it from freezing.
The engine coolant mixture used at the factory provides protec-
tion against freezing for temperatures as low as approximately–30 °C. The concentration should be checked before the start of
cold weather and anti-freeze added to the system if necessary.
WARNING
!●Do not open the reserve tank cap while the engine is
hot. The coolant system is under pressure and any
hot coolant escaping could cause severe burns.
CAUTION
!●Do 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 the aluminium components.●Do not top up with water only.
Water by itself reduces the rust-protective and anti-
freeze qualities of the coolant and has a lower boil-
ing point. It can also cause damage to the cooling
system if it should freeze. Do not use tapwater, as it
can cause corrosion and rust formation.

8 Automatic transmission fluid
*
E01000600134
The proper amount of automatic transmission fluid is essential
to the life and operation of the automatic transmission. Either
insufficient fluid or excessive fluid could cause transmission
trouble. The transmission fluid filler port cap is equipped with
a dipstick. Use the following procedure to check the fluid level.Procedure for checking the fluid level 1. Check the fluid level after the vehicle has been driven
enough to warm up the transmission fluid.
2. Park the vehicle on a flat, level surface and apply the
parking brake.
3. With the engine idling and the brake pedal fully
depressed, move the transmission selector lever through
all the positions from the “P” (PARK) to “D” (DRIVE),
stopping momentarily at each position.
4. Move the selector lever to the “P” (PARK) position.
5. Remove the dipstick and wipe it with a clean lint-free
cloth.
6. Reinsert the dipstick as far as it goes.7. Remove dipstick and read the oil level.
The fluid level should always be between the two marks
on the dipstick.
Recommended fluidUse only “DIA QUEEN ATF SP III” transmission fluid to
ensure optimum transmission performance.
WARNING
!●Do not spill the fluid onto a hot exhaust manifold
during topping up or inspection, or a fire may occur.

Check the float (A) is between the “FULL” and “EMPTY” on
the washer fluid reservoir.
If the level is low, replenish the container with washer fluid.NOTE●The washer fluid container serves the windscreen, rear
window and headlamps*.During cold weather To ensure proper operation of the washers at low temperatures,
use a fluid containing an anti-freezing agent.
Brake fluid/Clutch fluid
*
E01000800501
The brake fluid and the clutch fluid share reservoir tank.To check the fluid levelThe fluid level must be between the “MAX” and “MIN” marks
on the reservoir.
The fluid level is monitored by a float. When the fluid level
falls below the “MIN” mark, the brake fluid warning lamp
lights up.
The fluid level falls slightly with wear of the brake pads, but
this does not indicate any abnormality.
If the fluid level falls markedly in a short length of time, it indi-
cates leaks from the brake system.
If this occurs, we recommend you to have the vehicle checked.

Fluid typeUse brake fluid conforming to DOT3 or DOT4 from a sealed
container. The brake fluid is hygroscopic. Too much moisture
in the brake fluid will adversely affect the brake system, reduc-
ing the brake performance.

CAUTION
!●Take care in handling brake fluid as it is harmful to
the eyes, may irritate your skin and also damage to
painted surfaces.●Use only the specified brake fluid.
Do not mix or add different brand of brake fluid to
prevent chemical reaction.
Do not let any petroleum-based fluid touch, mix
with, or get into the brake fluid.
This will damage the seals.●Keep the reservoir tank cap closed to prevent the
brake fluid from deteriorating except maintenance.●Clean the filler cap before removing and close the
cap securely after maintenance.

To check the fluid levelCheck the fluid level in the reservoir while the engine is idling.
Check to make certain that the power steering fluid level is
always between the “MAX” and “MIN” level markings on the
fluid reservoir and refill the fluid, if necessary.Recommended fluidUse “Genuine MITSUBISHI Power Steering Fluid” or “ATF
DEXRON III / DEXRON II”.
Battery
E01001201277
The condition of the battery is very important for quick starting
of the engine and proper functioning of the vehicle’s electrical
system. Regular inspection and care are especially important in
cold weather.NOTE●After replacing the battery, the electronic control system
data for the automatic transmission, etc., will be erased.
As a result, shift shocks may occur.
Shift shocks will become smoother after several changes
in speed.
●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
The electrolyte level must be between the specified limit on the
outside of the battery. Replenish with distilled water as neces-
sary.
The inside of the battery is divided into several compartments;
remove the cap from each compartment and fill to the upper
mark. Do not over-replenish beyond the upper mark because
spillage during driving could cause damage.
Check the electrolyte level at least once every four weeks,
depending on the operating conditions.
If the battery is not used, it will discharge by itself with time.
Check it once every four weeks and charge with low current as
necessary.

During cold weatherThe capacity of the battery is reduced at low temperatures. This
is an inevitable result of its chemical and physical properties.
This is why a very cold battery, particularly one that is not fully
charged anyway, will only deliver a fraction of the starter cur-
rent which is normally available.
We recommend you to have the battery checked before the start
of cold weather and, if necessary, have it charged or replaced.
This does not only ensures reliable starting, but a battery which
is kept fully charged also has a longer life.Disconnection and connectionTo disconnect the battery cable, stop the engine, first discon-
nect the negative (–) terminal and then the positive (+) termi-
nal. When connecting the battery, first connect the positive (+)
terminal and then the negative (–) terminal.
NOTE●Open the terminal cover (A) before disconnecting or con-
necting the positive (+) terminal of the battery.
●Loosen the nut (B), and then disconnect the battery cable
from the positive (+) terminal.Petrol-powered vehicles
