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

may result in failure of the mechanical as-
sembly.
Engine coolant/Plug-in
hybrid EV system coolant
E01000503466
To check the coolant level
A transparent engine coolant reserve tank (A)
and EV cooling system reserve tank (B) is lo-
cated in the engine compartment.
The coolant level in this tank should be kept
between the “LOW” and “FULL” marks
when measured while the engine and the
plug-in hybrid EV system are cold.
