Coolant Change schedule?

[mikecronis]

How often is the battery coolant changed? Maintenance schedule says to check it at 3 years, so I suspect perhaps coolant-level and possibly acidity value, but I could probably do that myself?
If it's similar to GM EV cars, it's probably 5 years.

I think maintenance says every 4 years for coolant. 2 years is time for the brake fluid change along with cabin filter.
