If the level should drop below the “LOW” or
“L” level on the reserve tank, open the lid and
add coolant.
Also, if the reserve tank is completely empty,
remove the radiator cap (C) and add coolant
until the level reaches the filler neck, or
remove the reserve tank cap (D) and add
coolant until the level reaches the “FULL” or
“F” level.
The coolants contain an ethylene glycol anti-
corrosion agent. Some parts of the Hybrid EV
System are cast aluminium alloy, and peri-
odic changing of the coolants are necessary to
prevent corrosion of these parts.
MITSUBISHI MOTORS GENUINE Coolant
has excellent protection against corrosion and
rust formation of all metals including alumin-
ium and can avoid blockages in the radiator,
heater, cylinder head, engine block, etc.
Because of the necessity of this anti-corrosion
agent, the coolant must not be replaced with
plain water even in summer. The required
concentration of anti-freeze differs depending
on the expected ambient temperature.
Above -35 °C: 50 % concentration of anti-
freeze
Below -35 °C: 60 % concentration of anti-
freeze
If the temperatures in your area drop below
freezing, there is the danger that the coolant
in the Hybrid EV System or radiator could
freeze and cause severe damage to the Hybrid
EV System and/or radiator. Add a sufficient
amount of anti-freeze to the coolant to pre-
vent it from freezing.
The concentration should be checked before
the start of cold weather and anti-freeze
added to the system if necessary.

Open the washer fluid reservoir cap, pull out
the tube while blocking the cap hole (A) with
your finger, and inspect the amount of washer
fluid that remains in the tube.
If there is not enough washer fluid left in the
tube, replenish the washer fluid up to the
“FULL” line.
Do not open the radiator cap (C) or the
reserve tank cap (D) while the Hybrid EV
System is hot. The coolant system is under
pressure and any hot coolant escaping
could cause severe burns.
Anti-freeze
Use “MITSUBISHI MOTORS GENUINE
SUPER LONG LIFE COOLANT PRE-
MIUM” or equivalent*.
*: Similar high quality ethylene glycol based
non-silicate, non-amine, non-nitrate and
non-borate coolant with long life hybrid
organic acid technology
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 alu-
minium components.
Do not use water to adjust the concentration
of coolant.
Concentrations exceeding 60 % will result in
a reduction of both the anti-freeze and cool-
ing performance thus adversely affecting the
Hybrid EV System.
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 boiling point. It can also cause
damage to the cooling system if it should
freeze. Do not use tap water, as it can cause
corrosion and rust formation.
