The letter 'A' with a circle in the car refers to the Auto Start-Stop System. Its function is that when this switch is turned on, the vehicle will not continue moving after braking, even if the brake is released. It automatically cancels when the accelerator is pressed, effectively protecting the engine from damage. The location of the Auto Start-Stop System: It is positioned on the car's center console, next to the gear shift lever. The working principle of the Auto Start-Stop System is: When the vehicle cannot move forward due to traffic congestion or at an intersection, and the driver presses the brake pedal to stop and shift into neutral, the system automatically detects that the engine is idling, not in gear, the wheel speed sensors of the anti-lock system show zero, and the electronic battery sensor indicates there is enough energy for the next start.

The indicator light on the car's dashboard with an 'A' inside a circle is actually the symbol for the auto start-stop system. The 'A' stands for Auto, and the circle likely represents the system's active status. When the light is on, it means the engine will automatically shut off when the vehicle is stopped, such as at a red light, helping you save fuel and be more environmentally friendly. When the light is off, it indicates the function is disabled. After years of driving, I often see this light on in city traffic jams. There's a slight vibration when the engine restarts, but you get used to it, and it does save a noticeable amount of fuel. However, it's important to note that if the light stays on constantly or doesn't come on after starting the car, there might be a system malfunction, such as a dead battery or sensor issues, and it's best to get it checked early. Checking the light's status before long drives can reduce engine wear, ensuring safety and saving money.

This icon is the auto start-stop function indicator. When the 'A with a circle' is lit, it means the system is active. It shuts off the engine when stopping to save fuel and automatically restarts when the traffic light turns green. As a young car owner, I often see this light during my daily commute in traffic jams. It's quite effective for saving fuel, but the slight vibration at every start can be a bit annoying. If you don't like it, you can manually turn off the system by pressing a button on the steering wheel or control panel. If the light is off, the system might be disabled or there could be an electrical issue—simply check the fuse or switch. Overall, it makes driving more convenient, especially for short city trips.

The A with a circle light on the dashboard is the auto start-stop system indicator. When lit, it means the function is active, and the engine stops when parked to reduce emissions. I pay close attention to it while driving because it makes less noise during startup, but if the light is off, the system may not be working, affecting fuel efficiency. Normally, you can easily toggle it on or off with a button press – simple and convenient to control.

How is the toll charged for temporary license plates on highways?

Temporary license plates and regular license plates are charged the same toll on highways. However, it's important to note that when using temporary license plates on highways, you must confirm the nature of the temporary plates. If traveling out of the city, you need to display temporary plates with a brown-yellow background, black characters, and black borders, and they must be affixed both on the front and rear of the vehicle to avoid traffic violations on the highway. Precautions for using temporary license plates: 1. Validity period of temporary license plates. Temporary license plates have a limited validity period, which can be 15 days, 30 days, or 90 days. For temporary driving across administrative regions, the validity period does not exceed 30 days. When using temporary license plates, be mindful to avoid expiration. If the temporary plates expire, you need to reapply for new ones, with a maximum of three applications per vehicle. 2. Penalties for running red lights and illegal parking. Whether driving on highways or in urban areas, temporary license plates and regular license plates have the same legal effect. If traffic violations occur, penalties will be imposed accordingly, especially for running red lights, which will result in a 6-point deduction if caught. Drivers are advised not to attempt such violations. 3. Penalties for expired plates. If temporary license plates are found to be expired, the driver will face a 12-point deduction and a fine of 200 RMB.
