It uses an EFB (enhanced flooded) battery, typically on stop-start trims. An EFB or AGM in Group 35 is the correct replacement. A plain flooded battery is not recommended. A 540-640 CCA rating is typical for this class. Matching or slightly exceeding the OEM figure is fine; going below it risks hard starts in winter. Group 35 defines the case size and terminal layout (standard-terminal layout), so any reputable Group 35 battery will fit the tray and connect correctly.
