Why does it mean when slip light is on?

The slip light relates to the traction control system (TCS). The TCS is a system that helps prevent wheels from spinning, especially when starting on slippery surfaces. It does this by reducing engine power and/or applying the brakes to specific wheels. The slip light comes on when there is a problem with the TCS. This could be due to low brake fluid, a sensor issue, or a system problem. Sometimes, the slip light may come on briefly and then turn off. This could just be a glitch in the system and isn't necessarily cause for concern. However, if other warning lights or strange symptoms accompany it, it's best to get the car checked out.
