  • The ISG related sensors or system error occurs.

The yellow AUTO STOP indicator () on the instrument cluster will stay on.

WARNING

When the engine is in Idle Stop mode, it's possible to restart the engine without the driver taking any action. Before leaving the car or doing anything in the engine room compartment, stop the engine by turning the ignition switch or ENGINE START/STOP button to the LOCK/OFF position or removing the ignition key.

NOTICE

  • If the ISG system continuously does not work correctly, have your vehicle inspected by a professional workshop as soon as possible. Kia recommends that you contact an authorised Kia dealer/service partner.

  • When the ISG OFF button light comes on, it may stop illuminating after driving your vehicle at approximately 80 km/h for a maximum of two hours and setting the fan speed control below the 2nd position. If the ISG OFF button light blink continuously in spite of the procedure, have your vehicle inspected by a professional workshop as soon as possible. Kia recommends that you contact an authorised Kia dealer/service partner.

  • If the AGM battery is reconnected or replaced, ISG system will not operate immediately. If you want to use the ISG system, the battery sensor needs to be calibrated for approximately 4 hours with the ignition off. Before calibration, turn the ignition on and off 2 or 3 times.

To help understand the ISG

  • Q. What is ISG? And what is the function of it?

    A. ISG is an abbreviation of Idle Stop and Go. The feature contributes to protecting the environment and improving fuel economy by automatically shutting down the engine when a vehicle comes to a stop.

  • Q. How does the ISG work?

    A. In the case of AT/IVT/iMT/DCT if a driver presses the brake to stop the vehicle, the engine is automatically shut off; if the driver releases the brake, the engine will restart. For MT, if a driver releases the clutch pedal in the N (Neutral) position, the engine is shut down; if the driver steps on the clutch pedal the engine will automatically restart. The ISG is operated only when the seat belt is fastened. The driver doesn't need to use the key or press the ENGINE START/STOP button for restarting.

  • Q. Does the ISG work every time?

    A. No, it doesn't. The vehicle selectively operates ISG considering all safety matters. It does not function when the vehicle is driving on steep hills (not applied to MT), and the vehicle requires air conditioning/heating or battery protection. For additional information on the safety conditions, please refer to the Owner's manual.

  • Q. How can I deactivate the ISG feature?

    A. You can just press a button “ISG Off”. Note that the ISG feature is reactivated if you start the engine using your key or the ENGINE START/STOP button.

  • Q. The engine restarted even if I didn't operate any of it. Why did it happen?

    A. If required, the feature automatically starts the engine after monitoring the vehicle conditions including the battery and the air conditioning system.

  • Q. Does the air conditioning work if the engine is shut down by ISG?

    A. No, it doesn't. In that case, the vehicle operates only the blower. If the vehicle's interior temperature is too warm, the engine will restart to operate the air conditioning.

  • Q. Can the frequent use of ISG lead to undermining the durability of vehicle components?

    A. Not at all. We have enhanced the durability and performance of parts — such as a starting motor (starter), batteries and others — required for ISG. Also, for your safety, we applied safety logic to the system.
