Fuel tank capacity can change by drivetrain, hybrid system, grade and model revision. A model badge alone is not sufficient to apply a fuel capacity.
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.
