How these references affect your decision

Engine coolant is not inverter coolant

Toyota specifies a separate inverter circuit. The engine quantity also differs between cold-climate and non-cold-climate equipment, so the engine and inverter capacities are not one combined refill amount.

Never open a hot cooling system or work on hybrid high-voltage components based on capacity figures.

Engine and inverter coolant service reference

Use Toyota Super Long Life Coolant when servicing the cooling systems; the manual lists gasoline-engine and inverter capacities separately.
