I've noticed that the DW-1 fluid that Honda is now using, seems to retain it's performance a bit better than the old ATF-Z1, but I would still drain and refill at least every 30k.
The Fit only holds about 6 qt of fluid total, but the drain and refill will remove almost 50% of the old fluid.
I would drain and refill once now, and again in 5k, then do it every 30k thereafter.
If you follow the Maintenance Minder, it will usually alert you to do the first change at about 60k, then every 30k thereafter.
