Kia Optima: TCS ON/OFF MODEIn the TCS ON mode, the indicator in the instrument cluster will not be illuminated.
The 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.
To switch to TCS OFF mode, press the TCS switch. System will be deactivated and the TCS indicator in the instrument cluster 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.
