Buick TC/slash yellow light switch is located on the center console panel. Below is an introduction to the TC/slash yellow light: 1. Function of the yellow light: When the yellow light is on, it indicates that the vehicle's traction control system is turned off. Simply turn on the traction control system, and the yellow light will go off. 2. Meaning of the traction control system: Traction Control System, abbreviated as TCS. 3. Function of the traction control system: The traction control system controls the torque output of the engine, thereby preventing the drive wheels from spinning on slippery surfaces such as snow, ensuring smooth starting and acceleration of the vehicle.
Last time I drove a Buick Excelle, I encountered a similar issue. That TC slash yellow light is the warning indicator for the Traction Control System. Its switch is hidden on the control panel to the left of the steering wheel, near the headlight adjustment knob. Look for a small button labeled 'TC'—pressing it toggles the system on/off. If the system is turned off, the light will glow yellow. During daily driving, I make it a habit to check the switch status, especially when driving in rain or snow—keeping the system active prevents skidding. But if you genuinely need to disable it (like when stuck in mud), a quick press does the trick. Most Buick models follow this design; for instance, the Regal has it in a similar location. The key is not to rush driving off—first confirm whether the light is in its normal 'off' state. If it indicates a malfunction, head to the repair shop immediately—safety comes first. I also took the chance to review the manual to reinforce my memory.
As a new car enthusiast, I was quite curious about the TC/slash yellow light when I first bought my Buick. The light appears on the left side of the dashboard, with an icon resembling a wheel with a slash, indicating that the traction control is either turned off or malfunctioning. Finding the switch is easy—it's located in the button cluster on the left side of the steering wheel. Just press the round button marked with 'TC' to toggle the system on or off. When driving, if you notice the light is on, be cautious, as turning off the system can make the car more prone to losing control on slippery roads. I rarely touch it, only briefly disabling it when climbing steep slopes. I recommend checking the diagrams in your user manual, as the switch position may vary slightly between different Buick models, but it's always within easy reach of the driver for convenient operation. Developing a habit of checking can help reduce unexpected incidents. Since adopting this practice, I've felt more at ease while driving.
