Kia Optima: Traction Control Indicator Lights

The TCS indicator will illuminate when the ignition key is turned to the “ON” position, but should go off after 3 seconds. It means the TCS is in the stand-by status and at the moment of the actual operation of the TCS, the indicator will blink.

Press the TCS switch, then the system will be deactivated and the TCS indicator will illuminate.

If the TCS indicator stays on in the TCS ON mode, take your car to your Authorized Kia Dealer and have the system checked.
