Level and compatibility: Use the specified fluid and the transmission-specific level-check procedure. Conventional ATF, belt-CVT fluid and manual gear oil are not interchangeable.
Schedule applicability: Use the severe schedule when driving mainly on trips under 5 miles (under 10 miles in freezing weather), above 90°F/32°C, in extensive idling or stop-and-go use, with a roof rack or on mountain roads, or on muddy, dusty or de-iced roads. Occasional severe use follows the normal schedule. U.S. schedules only.
Service conditions: Historical manual change capacity: 2.7 L. Confirm the current Honda replacement fluid before buying; do not treat the original ATF-Z1 name as a verified current retail recommendation.
