The ESC indicator will illuminate when the ignition switch is turned ON, but should go off after approximately 3 seconds. When the ESC is on, it monitors the driving conditions and under normal driving conditions, the ESC indicator will remain off. When a slippery or low traction condition is encountered, the ESC will operate, and the ESC indicator will blink to indicate the ESC is operating.
If this indicator illuminates and stays on, the ESC may have malfunctioned. Take your vehicle to an authorized Kia dealer and have the system checked.
