CIRCUIT MODE is a utility application designed for T-Connect subscribers, enabling seamless interaction with compatible Toyota vehicles. Users can monitor essential vehicle status indicators such as fuel levels and driving distance through the My GR feature. To access the app, a Toyota account is required, which has recently been updated from the previous Toyota/Lexus common ID.

One of the standout features of CIRCUIT MODE is the special vehicle setting known as "CIRCUIT MODE." This mode unlocks the vehicle's inherent capabilities by enhancing acceleration response and increasing speed limits when entering a circuit, facilitated by GPS positioning. The app allows users to easily toggle this mode on and off, as well as modify various settings. Additionally, the app provides access to a range of Toyota-related information, including links to the official Toyota Gazoo Racing website and YouTube channel.
