Most car air conditioning systems have three basic adjustments: air volume, temperature, and air direction. The temperature button is usually displayed as a "thermometer" or has red and blue color markings on both sides. By turning the knob, the red area gradually increases the temperature, while the blue area does the opposite, gradually decreasing the temperature. More related information is as follows: 1. Air volume button: Also known as the fan speed button, the icon is a small "fan," and the appropriate air volume is selected by turning the knob. 2. Air direction adjustment: Most air direction adjustments are either button-operated or knob-operated, and they are more visually intuitive, displayed with an icon of a "seated person with air direction arrows." Options typically include blowing to the head, blowing to the head and feet, blowing to the feet, blowing to the feet and windshield, or blowing solely to the windshield. This is generally how air direction adjustments work in most vehicles, with only a few exceptions.

I've noticed that the buttons for adjusting the car's air conditioning temperature are usually the knob or button with plus and minus symbols on the center console. A simple turn or press can increase or decrease the temperature. Having driven for over a decade, the large knob on the air conditioning control panel is the most common to me—it's very convenient to turn left or right, and it's marked with temperature numbers or red/blue icons indicating the cooling/heating direction. Automatic air conditioning is even more hassle-free; after pressing the AUTO button, the system automatically maintains the set temperature, and you only need to adjust the comfort level with this knob. In high-end cars, sometimes there's a slider on the touchscreen for direct operation, while multi-zone air conditioning has additional buttons to adjust temperatures for different seats. Don’t forget to regularly check the air filter to ensure smooth adjustment, and setting it to around 23°C in summer is most comfortable to avoid heatstroke.

Is the Insurance Cost the Same for 5-Seater and 7-Seater Cars?

5-seater and 7-seater cars have different insurance costs. Below are the differences in insurance premiums between 5-seater and 7-seater cars: 1. Compulsory Traffic Insurance (CTI): This is an annual mandatory payment. For family cars, those with 6 seats or fewer cost 950 yuan per year, while those with more than 6 seats cost 1,100 yuan. 2. Seat Insurance: Also known as Passenger Liability Insurance, 7-seater cars have two more seats than 5-seater cars, resulting in a cost increase of approximately 100 yuan. Additional Information: Below are other differences between 5-seater and 7-seater cars: 1. Space: 7-seater SUVs are modified from 5-seater models by adding an extra row of seats. If you frequently need 7 seats, purchasing an MPV will provide a higher level of overall comfort. 2. Vehicle Body Markings: Enforcement varies by region. Generally, as long as the vehicle is not used for commercial purposes, even 7-seater cars do not need to display markings such as 'Approved Capacity: 7 Persons' on the body. However, in some areas where private cars are often used for commercial purposes, for unified management, these markings may be required during annual inspections.

What Causes the Noise Outside the Window While Driving?

Noise outside the window while driving is usually caused by foreign objects like stones stuck in the tire tread. Here is some relevant information about tires: Tires are rubber products, and rubber deteriorates over time with use, so tires need to be replaced periodically. Under normal circumstances, tires installed on a car can last for four years, so it is recommended to replace them every four years. When purchasing new tires, always check the production date because tires also have a shelf life. Normally, unused tires have a shelf life of three years; if they have been sitting for more than three years, they should not be purchased.
