Home/2026 Sorento/Idle, Stop & Go (ISG) System
IDLE, STOP & GO (ISG) SYSTEM

ISG is designed to reduce fuel consumption by automatically shutting down the engine when the vehicle is at a standstill.

When the ISG system is ON and the vehicle is at a standstill, the engine will stop, and the green AUTO STOP indicator on the Instrument Cluster will illuminate.

The engine will restart when the brake pedal is released or the shift lever is moved from D (Drive) to the R (Reverse) position or to Manual Shift mode.

When engine restarts, the green AUTO STOP indicator on the Instrument Cluster will turn off.

To deactivate the ISG System, press the ISG OFF button . If you press again, the system will be activated.

Quick Tips:

If the AUTO STOP indicator is solid yellow, the system is functional, but just has not met all its enabling criteria to activate ISG at that time

The ISG system is disabled when:

  • A seat belt is unfastened
  • The hood or a door is opened
  • Battery condition is poor
  • The front or rear defroster is turned on
  • Engine coolant temperature is low
  • The outside ambient temperature is too low/high
  • Emission control devices activate
  • The vehicle is on a steep slope

Reminders:

  • ISG is active by default at vehicle startup. When ignition is cycled, ISG will turn ON again
  • Under certain conditions, the engine will restart automatically even if the brake pedal is still depressed
  • If the AUTO STOP indicator is continuously blinking yellow and the ISG button LED is on, please contact an authorized Kia dealer

Certain features are available only on select Kia models.
