Where is the Buick TC Button Switch Located?

Buick TC button switch location is divided into the following two situations: 1. For older Buick LaCrosse models, the TC button switch is located below the gear shift lever. 2. For newer Buick LaCrosse models, the TC button shares the same button as the ESP system and is located on the center console. More relevant information is as follows: 1. When a Buick vehicle displays "TC," it indicates a malfunction in the traction control system. In this case, you should visit a Buick 4S dealership to have a technician read the fault code, identify the cause and location of the fault, and proceed with immediate repairs. 2. The traction control system is a driving assistance system in vehicles that controls the power delivered to the drive wheels. This system activates only when the drive wheels slip. If the drive wheels slip, the traction control system will limit the engine's power output and apply braking to the slipping drive wheels to prevent excessive slippage. 3. When the traction control system is active, the TC light on the dashboard will flash. The TC light remains off when the system is not in use.
I remember when driving a Buick, I often found the TC button near the steering wheel, located either on the left side of the center console or the lower edge of the dashboard, designed for convenient reach. TC actually stands for Traction Control System, which prevents wheel slippage on slippery surfaces, such as automatically intervening on rainy days—very practical. However, sometimes when trying to get out of mud, you need to manually turn it off. Finding the button isn't difficult; it usually has a small icon showing two wheels or labeled with TCS. When I drove the Envision, the button was right next to the driving mode switch area, a bit small and easy to miss. It's a good habit to check if the function is enabled every time you start the car to ensure driving safety. If you really can't find it, I recommend consulting the owner's manual or asking a 4S店 technician to avoid fumbling around while driving.
As a frequent driver, I must say the Buick TC switch is mostly located near the steering wheel area, close to the driver's hand for easy control. The exact position depends on the model: Regal or GL8 may have it among the button clusters below the center console, while Enclave often places it on the side of the driver's instrument panel. Turning off TC can help escape slippery conditions like snow or gravel roads, but it's generally not recommended to keep it off for long as the system stabilizes the vehicle. The button itself features a logo with wavy lines and a wheel symbol, and when lit, TC is active. This placement minimizes eye movement, enhancing safety. Make it a habit to check if it's on before driving, especially in bad weather. If you can't find it, avoid pressing other buttons blindly to prevent affecting handling.
