Kia K4: Warning and indicator lights / Indicator lights

Electronic Stability Control (ESC) indicator light

The ESC system is a critical safety feature of your Kia K4. This indicator light operates as follows:

• It illuminates for approximately 3 seconds as a system self-diagnostic check whenever you turn the ENGINE START/STOP button to the ON position.

• If the light remains illuminated, it indicates a malfunction in the ESC system. In this situation, have your Kia K4 inspected promptly by an authorized Kia dealer to ensure your safety systems are fully functional.

The indicator light will blink continuously while the ESC system is actively intervening to stabilize your Kia K4 during challenging road conditions. For more details, refer to the "Electronic Stability Control (ESC)" section of your owner's manual.

This light provides feedback on the active status of your stability systems:

• It will remain lit whenever you have manually deactivated the ESC system by pressing the dedicated ESC OFF button.

For more details, refer to the "Electronic Stability Control (ESC)" section.

AUTO HOLD indicator light

The Auto Hold system enhances convenience in your Kia K4, and its status is displayed as follows:

Immobilizer indicator light (with smart key)

This indicator provides status updates for the smart key system in your Kia K4:

• The light appears for up to 30 seconds when the vehicle detects the authorized smart key inside the cabin while the ENGINE START/STOP button is in the ACC or ON position. It will disappear once the engine is running.

• If the light blinks for a few seconds, it means the smart key is not detected within the Kia K4, and the engine will not start.

• If the light appears for 2 seconds and then disappears while the ENGINE START/STOP button is ON, but the vehicle fails to detect the smart key, please have your Kia K4 inspected by an authorized Kia dealer.

• If the light blinks continuously, it signals an immobilizer system fault requiring immediate professional attention.

• This light will blink when your Kia K4 smart key battery is critically low. In this condition, you will not be able to start the engine using the standard method; you must press the ENGINE START/STOP button directly with the smart key body to start your Kia K4. (For more comprehensive details, refer to the "Immobilizer system" section of your manual).

• If the light blinks due to an internal system malfunction, have your Kia K4 inspected immediately by an authorized Kia dealer.
