BMW coolant has a boiling point of 107°C. It is recommended to choose brand-name coolant produced by reputable manufacturers to ensure quality. Additionally, select a coolant suitable for the local climate and vehicle model. Generally, the freezing point of the chosen coolant should be 10-15°C lower than the local minimum temperature. Coolant composition: Coolant primarily consists of ethylene glycol and water, meaning it is an aqueous solution of ethylene glycol, which has certain electrical conductivity. Coolant functions: Coolant prevents the freezing of the liquid in the cooling system during cold winter parking, which could otherwise cause the radiator to crack or the engine cylinder block or head to freeze and damage. Coolant is not just for winter use but should be used throughout the year. Regardless of the color of the coolant, it should maintain a certain level of transparency; cloudy products are not of good quality.

What are the advantages of car leather seats?

The advantages of car leather seats are easy to clean and good heat dissipation. Below is a detailed introduction to the benefits of car leather seats: Easy to clean: Compared to fabric-covered seats, dust only settles on the surface of leather seats and does not penetrate deep into the seat. Therefore, a simple wipe with a cloth is enough to clean them. For fabric seats, you may need to purchase seat covers; otherwise, once they get dirty, stains might seep into the seat's interior. Better heat dissipation: Although leather can absorb heat, it performs better in dissipating heat. China's automotive industry has been developing rapidly in recent years and will continue to grow steadily in the future, leading to a high demand for seats. As a result, the passenger car seat industry still has significant growth potential.

What should be paid attention to when driving on the highway?

Here are the relevant precautions for driving on the highway: Strictly adhere to highway speed limits: This includes both the maximum and minimum speed limits. Do not exceed the maximum speed or drive below the minimum speed, as both can easily lead to safety accidents. On two-lane highways, use the left lane; on highways with three or more lanes, use the middle lane. The right lane often has many large trucks, so try to stay away from it. Check the vehicle's condition before entering the highway: Pay special attention to the fuel tank, tires, brakes, and water. If the tires are severely damaged, replace them first. If there are issues with the brakes, repair them promptly. Due to the high speeds on highways, the windshield can easily become covered with insect remains, and windshield washer fluid will be very useful in such situations.

What to Do If Something Falls into the Front Windshield Vent?

If something falls into the front windshield vent, you can use a vacuum cleaner or directly remove it. Below are the solutions for dealing with objects falling into the front windshield vent: Vacuum Cleaner: Turn on the vacuum cleaner and point its nozzle at the candle wax. Then, use a hard wire to break the candle wax into pieces, which can then be sucked away by the vacuum cleaner. Note that a large vacuum cleaner is needed, not a handheld car vacuum. If the angle between the windshield and the dashboard is too small to operate, then this method won't work. Remove the Front Windshield to Retrieve the Object: If the above method doesn't work, the only option is to remove the windshield. However, this is not cost-effective. First, the cost of removing and reinstalling the dashboard is high. Second, the process may loosen or break the dashboard clips, which could lead to unusual noises while driving.

How many kilometers does a car travel per minute?

If the car's speed is 120 kilometers per hour, the car can travel 2 kilometers in one minute. Below are some precautions to consider while driving: Pay attention to road conditions: During driving, we must always keep a clear mind and continuously monitor road conditions, prioritizing safety above all. Remember not to show off or overtake recklessly. Adopt the attitude of "waiting three minutes is better than rushing one second" while driving. Fatigue driving: Many accidents occur due to drivers being fatigued. Fatigue driving can impair judgment, reduce reaction time, and affect concentration while driving. Therefore, it is crucial to avoid driving while fatigued. Drunk driving: Drunk driving is a severe issue. The saying "Don't drink and drive, don't drive after drinking" is widely known. However, we must not just say it; we must apply it in our daily lives and treat it as a driving motto for every driver, constantly reminding ourselves.

Where is the windshield wiper switch located?

The windshield wiper switches for the vast majority of vehicles currently on the market are positioned on the right-hand stalk behind the steering wheel, typically in a lever-style design. Similar to the light control stalk, the wiper stalk features numerous function symbols. Although the symbols and their placement vary across different brands, the functionalities are generally similar. Below is relevant information about windshield wipers: 1. It is essential to keep the wipers clean regularly. Owners can use water-dampened tissue or cotton cloth to wipe along the rubber blades, removing accumulated dust. Avoid prolonged contact between the wipers and the windshield, as the glass temperature can become extremely high on sunny days, which can severely damage the rubber's elasticity and cause premature hardening. Also, refrain from using ammonia-based cleaners. Laundry detergent or certain household cleaners contain ammonia, which can accelerate rubber hardening, making them unsuitable for the wiper fluid reservoir. 2. When the rain is light and the windshield is not heavily covered with water, set the wiper stalk to the low-speed intermittent setting, marked as LO or LOW. In heavier rain, when the windshield quickly becomes obscured by water, significantly impairing visibility, switch the wiper to the high-speed continuous setting, marked as HI or HIGH, to continuously clear water from the windshield.
