Hyundai Kona 2023 Idle Stop and Go (ISG) System User Guide
The Hyundai Kona 2023 comes with an Idle Stop and Go (ISG) system, which is designed to improve fuel efficiency and reduce emissions by automatically turning off the engine when the car comes to a stop. This feature is especially useful in heavy traffic or long waits at traffic signals, where the car remains stationary for extended periods of time. When the driver takes their foot off the brake pedal, the ISG system quickly restarts the engine and the car is ready to go again.
The ISG system can be turned off manually if the driver prefers to keep the engine running at all times. The Hyundai Kona 2023’s ISG system is one of the many features that contribute to the car’s eco-friendliness and efficiency.
