Select engine oil of the proper SAE vis-
cosity number according to the atmos-
pheric temperature.
SAE 0W-16, 0W-20, 5W-20, 0W-30, 5W-
30 and 5W-40 engine oils can only be
used if they meet ACEA A3/B3, A3/B4 or
A5/B5 and API SG (or higher) specifica-
tions.
Use engine oil conforming to the follow-
ing classification:
• API classification: “For service SG” or
higher
• ILSAC certificated oil
• ACEA classification:
“For service A1/B1, A3/B3, A3/B4, or
A5/B5”

A transparent engine cooling system reserve
tank (A) and EV cooling system reserve tank
(B) are located in the engine compartment.
The coolant levels in these tanks should be
kept between the “LOW” or “L” and “FULL”
or “F” marks when measured while the
Hybrid EV System is cold.
Each of the cooling systems is a closed sys-
tem and normally the loss of coolant should
be very slight. A noticeable drop in either of
the coolant level could indicate leakage. If
this occurs, have the system checked at an
authorised MITSUBISHI MOTORS dealer as
soon as possible.
Recommended engine oil vis-
cosity
Use of additives is not recommended since
they may reduce the effectiveness of addi-
tives already included in the engine oil. It
may result in failure of the mechanical
assembly.
If those classifications are not available, con-
tact an authorised MITSUBISHI MOTORS
dealer.
