What Issues Should Be Paid Attention to When Buying a Car?

At what temperature in the car will the car perfume explode?

If the perfume bottle is spherical, hemispherical, or other shapes similar to a convex lens, the bottle can create a focal point under sunlight at an appropriate angle. The temperature at the focal point can exceed 100°C, which is enough to ignite the alcohol in the perfume and may cause an explosion. Precautions for using car perfume are as follows: 1. Quality assurance: First, no matter what type of car perfume you choose, the product must have a Chinese description including the product name, company name, company address, contact information, and precautions. Low-quality perfumes made with chemical fragrances and industrial alcohol can be harmful to health and affect driving safety if smelled for a long time. 2. Placement: The placement of car perfume is very important. First, it should not block the driver's view. Second, it should not be placed above an airbag indicator. The placement should avoid direct sunlight as much as possible. Cup holders and storage compartments are good placement options. 3. Scent selection: The choice of perfume scent is also important. It is recommended to choose refreshing and calming fruity or floral scents when purchasing, such as the fresh scent of mint and lemon, which can help alleviate fatigue during driving. 4. Changing perfume: When switching to another scent, make sure the original perfume's fragrance has completely dissipated. Otherwise, mixing two different scents may have a counterproductive effect, possibly making passengers uncomfortable and, in severe cases, affecting the driver's mood, thereby compromising driving safety.

What Do the Yellow and Red Dots on Tires Represent?

Here are the meanings represented by the yellow and red dots: 1. The solid red dot indicates the position with the maximum longitudinal vibration of the tire, meaning this is the heaviest spot, referred to as the center of gravity in technical terms. As we all know, tires generate vibrations during rotation, and this spot is where the vibration is the strongest. 2. The hollow yellow dot is the opposite of the solid red dot, representing the position with the minimum longitudinal vibration of the tire, meaning this is the lightest spot, known as the tire's light point. Here is some additional information: In addition to the two dots on the tire, some wheel rims also have markings—a solid white dot. Some rims may not have this marking. This solid white dot represents the light point of the rim, indicating the lightest position.

How to Replace the Air Conditioning Filter in the Touareg?

The specific steps to replace the air conditioning filter in the Touareg are as follows: 1. Open the glove box.
