What is an LLC on a Toyota Prius and what maintenance does it need?

An LLC, or Low-Temperature Coolant, in a Toyota Prius refers to the coolant used in the vehicle's hybrid system to manage temperature effectively. Maintenance for this system includes regular checks of the coolant level and condition, ensuring there are no leaks, and replacing the coolant as specified in the owner's manual, typically every 100,000 miles or so. Additionally, it's important to inspect related components such as hoses and the radiator for any signs of wear or damage to maintain optimal performance.
