The tc displayed on the car means the traction control system is working. The traction control system, also known as the track control system or drive anti-slip system, is part of the car's active safety system. Its function is to ensure the car obtains optimal traction under various driving conditions. The control device of the traction control system is a computer that monitors the speed of all four wheels and the steering wheel angle. When the car accelerates, if the computer detects an excessive speed difference between the driving wheels and non-driving wheels, it immediately determines that the driving force is too high and sends a signal to reduce the engine's fuel supply, thereby lowering the driving force and decreasing the slip rate of the driving wheels. The computer also uses the steering wheel angle sensor to understand the driver's steering intention, then employs the left and right wheel speed sensors to detect the speed difference between the wheels, assessing whether the car's turning degree matches the driver's steering intention.

Do You Need to Use Turn Signals When Reversing?

When reversing and making a turn, you need to use the turn signal. Here is the correct way to use turn signals: 1. Left turn signal: You should turn on the left turn signal in advance when turning left, changing lanes to the left, preparing to overtake, leaving a parking spot, or making a U-turn. This is because entering a highway involves turning left, while exiting a highway involves turning right. Similarly, when merging from an auxiliary road into a main road, you should use the left turn signal. 2. Right turn signal: You should turn on the right turn signal in advance when turning right, changing lanes to the right, returning to the original lane after overtaking, or parking by the roadside. When exiting a roundabout, use the right turn signal to alert vehicles behind and oncoming traffic. This is a clear regulation in the new traffic rules. Previously, many drivers would use the left turn signal when entering a roundabout.
