Ensure that the car's engine is turned off.
Locate the TCS button, which is usually found near the gear shifter or on the center console.
Press and hold the TCS button for a few seconds until the TCS light turns off.
If the TCS light does not turn off after a few seconds, repeat steps 2 and 3.
If you cannot turn off the TCS light by pressing the button, there may be an underlying issue with the TCS system in your vehicle. In that case, it's best to consult with a qualified mechanic for further diagnosis and repair.
