Automotive antifreeze serves the following purposes: 1. Provides freeze protection for the engine against low-temperature environments; 2. Prevents the coolant from freezing and cracking the radiator or damaging the engine cylinder block and cylinder head when parked in cold winter conditions; 3. Offers efficient heat dissipation. Also known as engine coolant, automotive antifreeze contains substances that lower the freezing point of water, allowing vehicles to operate in winter temperatures while keeping the cooling system from freezing. The composition of automotive antifreeze includes: inorganic compounds like calcium chloride, and organic compounds such as methanol, ethanol, ethylene glycol, glycerin, lubricating oil, and purified water.

How to Adjust the Sound Effects of the 2020 Audi A6L?

From the MMI main menu of the Audi A6L, enter the "Sound" option. There are four sub-menus under this level, and the latter ones are relatively easy to understand. The first one is the DSP menu, which is only available for BOSE audio systems. The first item in DSP is sound field positioning, which can be set to "All" or "Front". This setting depends on the number of people in the car. If only the front seats are occupied, select "Front"; if the car is full, choose "All". It simulates different sound field positioning effects through the output of a 5.1-channel speaker combination.

What are the dimensions of the Model 3 windshield?

Tesla Model 3 front windshield sunshade product dimensions: 15.5*89*134cm, packaging dimensions: 94*10cm, packaging weight: 340g. Extended information about the windshield is as follows: 1. Regularly check the wipers: Wipers are one of the main sources of damage to the front windshield. Over time, wipers can age, and if the end of the wiper arm directly rubs against the windshield, it not only fails to clean rainwater effectively but can also scratch the glass. Additionally, wipers that accumulate dust can scratch the front windshield, leaving small scratches and fine lines. Experts point out that at high speeds, even these tiny scratches can cause the windshield to shatter. Although the probability is low, some sudden windshield cracks on highways with no apparent cause are actually the result of these accumulated small scratches. 2. Cleaning the front windshield: Always use designated windshield cleaning fluid, which contains ingredients that dissolve grease and improve the wetting interface of the glass, aiding in its maintenance. When there are obstacles like snow, ice, mud clumps, or hardened bird droppings on the glass, avoid using the wipers to prevent damage to the wiper blades, wiper motor, and the glass itself. 3. Window film: There are various types of films for the front windshield, including anti-explosion films and UV protection films. It is advisable to choose films from reputable brands like 3M or Johnson. Inferior quality films not only fail to provide the intended benefits but can also pose safety hazards due to issues like insufficient light transmission.
