How these references affect your decision

Oil-only or oil-and-filter service?

The Sienta Hybrid NHP170G source distinguishes 3.4 L for oil-only from 3.7 L when the filter is changed. The grade and applicable oil specification must be verified separately.

Follow Toyota's exact-vehicle procedure and final oil-level check.
