Kia Rio: ISG (Idle stop and go) system

Your vehicle may be equipped with the ISG system, which reduces fuel consumption by automatically shutting down the engine, when the vehicle is at a standstill. (For example : red light, stop sign and traffic jam) The engine starts automatically as soon as the starting conditions are met.

The ISG system is ON whenever the engine is running.

✽ NOTICE

When the engine automatically starts by the ISG system, some warning lights (ABS, ESC, ESC OFF, ESC or Parking brake warning light) may turn on for a few seconds. This happens because of low battery voltage. It does not mean the system is malfunctioning.
