The TRC OFF light on the dashboard indicates that the traction control system is turned off, and its functions are: 1. Improve the driving stability, acceleration, and climbing ability of the vehicle; 2. Enhance the safety performance of the vehicle; 3. Adjust ignition timing, reduce valve opening, decrease throttle, downshift, or brake the wheels to prevent wheel slip. Dashboard indicator lights and their functions are categorized as follows: 1. Door status indicator: Shows whether the doors are fully closed; 2. Battery indicator: Displays the working status of the battery; 3. Brake disc indicator: Shows the wear condition of the brake discs; 4. Oil pressure indicator: Displays the engine oil pressure; 5. Coolant temperature indicator: Shows the temperature of the engine coolant.
Hey, the TRAC OFF light on the dashboard is on, indicating that the traction control system is turned off. This system helps prevent skidding, especially in rainy or snowy conditions, by automatically applying brakes or reducing engine output when the wheels slip, making the car more stable. Having driven for many years, the most common reason for this light to come on is the driver accidentally pressing the switch button on the steering wheel or switching to sport mode in specific settings, which actively turns off the system. Sometimes, turning off TRAC when stuck in mud or sand allows the wheels to spin more powerfully, helping to get unstuck. But it's safer to keep it on normally, especially on slippery roads—having the light on can be dangerous. If you turned it off yourself, pressing the button again will turn the light off; if the light won't go off, it might be a system malfunction, like a sensor error or loose wiring, and you should get it checked at a repair shop.
