The reason for heavy brakes and failure to start is: The owner stepped on the brakes several times after turning off the engine, causing the vacuum in the brake booster to disappear. Without the booster assistance, it becomes difficult to press the brake pedal, and the booster pump does not operate when the engine is off. Solutions for heavy brakes and failure to start: 1. Try restarting the engine; 2. Press the brake pedal firmly; 3. After starting, normal operation will resume. Braking precautions: 1. During low-speed driving, emergency braking can be applied when encountering sudden events ahead by firmly pressing the brake pedal, but this should not be done at high speeds to avoid vehicle skidding or rollover; 2. During normal driving conditions, gradual braking is recommended—press the clutch pedal while releasing the accelerator pedal, shift to a lower gear, and after the speed decreases, release the clutch pedal and press the brake pedal until the vehicle comes to a complete stop.

During the period when the temporary license plate has expired but the official license plate has not yet been obtained, driving on the road is not allowed. Temporary license plates include: temporary license plates for administrative jurisdictions, temporary license plates for cross-administrative jurisdictions, temporary license plates for testing, and temporary license plates for special-type motor vehicles.

What are the symbols for internal and external air circulation in a car?

Internal air circulation is symbolized by a closed car interior with a circular arrow; external air circulation is represented by an open car with an air arrow pointing into the vehicle. External circulation mode uses a fan to draw outside air into the car, meaning the air passage between the exterior and interior is open. Even when the fan is off, airflow is still drawn into the car while driving, replenishing fresh air inside. Internal circulation mode closes the airflow passage between the inside and outside of the car. Without the fan, there is no airflow circulation, and when the fan is on, the airflow drawn in comes solely from inside the car, creating internal air circulation. Internal circulation primarily serves to promptly and effectively block external dust and harmful gases from entering the car, such as when driving through areas with smoke, dust, strong odors, or in heavy traffic, preventing harmful exhaust emissions from preceding vehicles.

What does AC mean in a car?

Car's A/C refers to the air conditioning regulation system. Below are the introduction and precautions regarding A/C: A/C in cars: It can be understood as air control or air conditioning, achieving cooling or heating through different operation modes of the air conditioning compressor, hence it has dual meanings of cooling and heating. After pressing the A/C button, the air conditioning starts to adjust the temperature according to the set value, and the air conditioning compressor will activate. If the car has been exposed to the sun for a long time outdoors, the correct approach is to first open the windows, turn on the air conditioning's external circulation mode to expel the hot air inside the car, wait for a few minutes, then turn on the A/C switch and set the circulation mode to internal circulation. Precautions for A/C in cars: In summer, the car's air conditioning must have A/C turned on; otherwise, the air blown out won't be cold. To quickly lower the temperature inside the car in summer, you can adjust the position of the air vents. According to the principle of air convection, hot air rises while cold air sinks. The air conditioning vents should be directed slightly upwards, utilizing the principle that hot air rises and cold air sinks. As the cold air descends, it can rapidly cool the interior of the car. Also, avoid placing decorations in front of the air conditioning vents as they can affect the cooling efficiency.
