Before applying a specification

Confirm the engineering configuration

CVT, automatic and hybrid transaxle systems must not be treated as interchangeable. Use the exact transmission and source reference before selecting any fluid.

Year ranges here describe the cited chassis coverage, not every option sold under the same model name worldwide. The actual service manual and fitted equipment take precedence.
