What does the Buick GL8 TC slash yellow light mean?

[VanKaleb]

Buick TC slash yellow light indicates that the traction control is turned off. When the driver normally starts the vehicle, this light will briefly illuminate. If the vehicle operates normally, the light will disappear. The function of the traction control system is to enable the car to obtain better traction under various driving conditions. Working principle of the traction control system: The traction control system uses a computer to detect the speed of the four wheels and the steering angle of the steering wheel. When the car accelerates, if it detects that the speed difference between the driving wheels and non-driving wheels is too large, the computer immediately judges that the driving force is excessive and sends a signal to reduce the fuel supply of the engine, thereby reducing the driving force and the slip rate of the driving wheel tires. Precautions for car traction control: On snowy or muddy roads, the traction control system can ensure smooth acceleration performance and prevent the vehicle from skidding or fishtailing due to the driving wheels slipping. Unless the vehicle is stuck in mud, sand, or snow and needs to increase the wheel rotation force, the TCS system can be turned off. In other cases, it is best to keep it turned on.
