What are the three golden principles of safe driving?

Safe driving relies on three golden principles: stay focused, observe carefully, and prevent in advance. Five key reminders are: 1. Strictly adhere to traffic regulations and never drive under the influence of alcohol; 2. Adjust your speed according to road conditions, traffic flow, and weather conditions; 3. Remember to take a break every two hours during long-distance driving; 4. Stay focused while driving and avoid using mobile phones or eating; 5. Maintain a good mental state for driving. Additional information: Correct driving posture is crucial for safe driving. It not only reduces fatigue during long drives and ensures good visibility but also makes driving actions more precise and swift. Driving posture mainly relates to the steering wheel and seat. After sitting in the driver's seat, you should first sit deeply in the back of the seat, allowing your lower back and shoulders to rest against the backrest.

What is the difference between lubricants and lubricating oils?

Lubricants and lubricating oils have the following differences: 1. Adhesion properties differ: When the friction part is in a static state, the lubricating grease can maintain its original shape, will not automatically flow away due to gravity, and will not slide off vertical surfaces or drip from gaps. This characteristic is very suitable for friction parts that start and stop frequently or are not often moved, for parts where it is very difficult to replenish lubricating grease (such as overhead crane lubrication points in the air), and for open or poorly sealed parts. 2. Temperature range differs: The working temperature range of lubricating grease is wider than that of lubricating oil. For example, general lithium-based lubricating grease can be used in the temperature range of -20~120℃, and general calcium-based or lithium-based lubricating grease can also be used at -20~60℃ or -20~120℃. However, a specific grade of lubricating oil has a much narrower temperature range of use. 3. Pressure resistance differs: The adsorption capacity of lubricating grease on metal surfaces is much greater than that of lubricating oil, and it can form a relatively strong oil film to withstand higher working loads. This is due to the large amount of polar substances contained in the lubricating grease. In addition, as a base grease, when polar additives are added, its sensitivity is also better than that of lubricating oil.

How to Repair Cracks in Leather Seats?

To repair cracks on leather seats, acrylic resin is required. The steps are as follows: 1. Locate the cracked areas on the leather seats. 2. Apply acrylic resin onto a towel. 3. Wipe the entire seat with the towel. 4. Apply leather adhesive to the cracked areas and dry with a hairdryer. 5. Spray another layer of resin adhesive and dry with a hairdryer. Additional Tips for Leather Seat Maintenance: 1. Proper Cleaning: When cleaning car leather seats, use appropriate cleaners to remove dust and stains from the leather surface. This prevents bacteria and pollutants from damaging the leather and ensures the seats remain dry and tidy. 2. Avoid Soaking: Soaking car leather seats can cause significant damage to the leather. 3. Keep Away from Heat Sources: Placing very hot objects near leather seats can lead to cracking. Also, avoid exposing leather seats to direct sunlight to prevent fading. 4. Apply Leather Conditioner: Properly conditioning the leather helps replenish nutrients, repair minor damages, and keeps the surface smooth and soft, enhancing the feel.

Why is the tire pressure monitor not displaying tire pressure?

There are mainly two reasons why a tire pressure monitor does not display the tire pressure, which are: 1. Insufficient battery power in the tire pressure sensor. Simply recharge the battery. 2. Failure to read the signal from the tire's internal monitor. Continue driving the vehicle for a while. Additional Information: Methods of tire pressure monitoring: 1. Direct tire pressure monitoring: Direct tire pressure monitoring devices use pressure sensors installed in each tire to directly measure the tire's air pressure. The pressure information is transmitted from inside the tire to a central receiver module via a wireless transmitter, and then the tire pressure data is displayed. When the tire pressure is too low or there is a leak, the system will automatically alert. 2. Indirect tire pressure monitoring: The working principle of indirect tire pressure monitoring is that when the air pressure in a tire decreases, the vehicle's weight will cause the rolling radius of that wheel to become smaller, resulting in a faster rotation speed compared to other wheels. By comparing the differences in rotation speeds between the tires, the system monitors the tire pressure. Indirect tire pressure alert systems essentially rely on calculating the rolling radius of the tires to monitor air pressure.

What Are the Indicator Symbols on the Car Dashboard?

Introduction to the main indicator symbols on the car dashboard: 1. Door Status Indicator: Shows whether the doors are fully closed. The corresponding light turns on when a door is open or not properly closed, alerting the driver that the door is not securely shut. The light turns off once the door is closed. 2. Parking Brake Indicator: This light turns on when the parking brake lever is pulled up. It automatically turns off when the handbrake is released. In some car models, this light may also indicate insufficient brake fluid. 3. Battery Indicator: Displays the working status of the battery. It lights up when the ignition is turned on and turns off after the engine starts. If it does not light up or remains lit continuously, the generator and circuit should be checked immediately. 4. Fuel Indicator: Alerts the driver when fuel is running low. When this light turns on, it indicates that the fuel is nearly depleted. Typically, the vehicle can still travel about 50 kilometers after the light comes on before running out of fuel. 5. Washer Fluid Indicator: Shows the level of windshield washer fluid. If the fluid is nearly empty, this light turns on, reminding the driver to refill the washer fluid. The light turns off after adding the cleaning solution.

What is the meaning of automotive metallic paint?

Metallic paint is created by mixing metal powder into the paint, which makes the painted metal surfaces appear more shiny and attractive. Viewed from different angles, due to light refraction, the color and even the car's contours will change, giving the vehicle's appearance a richer look. Automotive metallic paint is a high-end car coating made from metal powders such as copper and aluminum. It features a metallic luster texture that enhances the paint film's grade and fully highlights a noble, elegant temperament. There are generally two types: water-based and solvent-based. Since metal powders are unstable in water and air, often undergoing chemical reactions and deterioration, their surfaces require special treatment, making the metal powders used in water-based paints expensive and limited in application. Currently, it is primarily solvent-based. With the advancement of life and the continuous development of the automotive industry, the production of safe and environmentally friendly automotive paints can play a significant role in developing new paint markets. Metallic paint is harder than ordinary paint, making the car body less prone to scratches, and it can also showcase the beauty of the body's level. For those without a garage who can only park in open parking lots, this is a great boon.
