In a car, 'door' refers to the activation mode of the reading light. Here are detailed explanations about 'door' in a car: 1. 'Door' means the door. On the reading light, it means that when the car door is opened, the dome light will turn on. If the door is opened or not closed tightly, the light will also turn on, serving as a warning function. 2. Its main purpose is to facilitate getting in and out of the car at night. The reading light provides sufficient brightness for passengers when the interior light is insufficient, making it convenient for reading inside the car without affecting the driver's normal driving. 3. The reading light is connected to the cigarette lighter socket. When the switch is activated, it can emit lights of different colors. Currently, there are ordinary reading lights (with one bulb) and LED reading lights (with multiple LED lights) available for car interiors.

Why Did Baojun 730 Stop Production?

Baojun 730 stopped production primarily because the product itself failed to attract potential consumers. Competitor factors: Originally, the Baojun brand, which lacked brand advantages, held a unique positioning and product edge in third-, fourth-, and fifth-tier cities. It dominated this market segment with three major strengths: spacious interiors, low prices, and a dense sales network. However, after 2018, consumers developed a new round of car selection preferences, prioritizing higher quality and brand reputation. Product factors: Models like the Jetour X70, which offer superior safety, handling quality, spacious interiors, features, and powertrain advantages, proved far more appealing to consumers than the Baojun 730. The price gap between these two models has narrowed to the cost of a smartphone, making the Baojun 730 no longer the sole choice for this consumer segment.

What Causes the Noise from the Top Rubber of Mercedes-Benz Shock Absorbers?

If there is abnormal noise from the top rubber of the front shock absorber in a car, it is necessary to consider replacing the top rubber of the front shock absorber. The function of car shock absorbers: Shock absorbers are used to suppress the oscillation after the spring absorbs shocks and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of vibrations in the frame and body, thereby improving the smoothness of the vehicle's ride. When driving on uneven roads, although the shock-absorbing springs can filter out road vibrations, the springs themselves still have reciprocating motion, and the shock absorbers are used to suppress this spring bouncing. Replacement of the top rubber of the shock absorber: Before replacement, park the car on a flat surface and prepare new top rubber, a jack, and soapy water, which can also be replaced with water diluted with dishwashing liquid; then, use the jack to lift the part of the car body that needs to be replaced, stretching the spring for easier replacement.

What are the components of antifreeze?

The main components of antifreeze are: 50% purified water, 40% methanol, and 10% other substances. Methods for selecting antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. The freezing points of antifreeze available on the market include -15°C, -25°C, -30°C, -40°C, and other specifications. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Methods to determine if antifreeze is insufficient: Observe the antifreeze warning light on the dashboard. If it lights up, it is likely due to insufficient antifreeze, though it could also be caused by excessively high temperature inside the cylinder. Check the antifreeze reservoir. If the liquid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Check the water level scale markings on the antifreeze bottle. The normal antifreeze level should be between the maximum and minimum water level marks. Whether antifreeze is insufficient depends on the scale. If the antifreeze level is below the minimum mark, it indicates a shortage of antifreeze.
