How Should Drivers Conduct a 360-Degree Safety Check Around the Vehicle Before Getting In?

Here is an introduction to the method of conducting a 360-degree safety check around the vehicle before getting in: 1. The method of the 360-degree check: Before getting into the vehicle, drivers should develop the habit of walking around the car to inspect the vehicle's exterior and the surrounding area, including underneath the car. Starting from the front door, walk counterclockwise around the vehicle to check the exterior, tires, and license plate; observe for any signs of fluid leakage. Only after confirming there are no people, small animals, or other obstacles under or around the vehicle that could affect safe departure should the driver get in. 2. The reason for checking counterclockwise: Since China implements right-hand traffic, vehicles are generally parked on the right side of the road. Drivers need to enter the driver's seat from the left side. At this time, conducting a counterclockwise check starting from the left front door ensures the driver can see oncoming traffic and road conditions from behind, making it safer.

What is the function of replacing the oil filter?

The function of the oil filter is to remove impurities, gum, and moisture from the engine oil, delivering clean oil to various lubrication points. The following are the benefits of replacing the oil filter: 1. To reduce the frictional resistance between moving parts in the engine and minimize component wear, clean oil is continuously delivered to the friction surfaces of moving parts, forming a lubricating oil film for effective lubrication. 2. To filter out impurities, gum, and moisture from the oil. Engine oil inherently contains a certain amount of gum, impurities, moisture, and additives. During engine operation, metal wear particles, airborne contaminants, and oxidation byproducts can accumulate in the oil. If the oil is not filtered before entering the lubrication circuit, these contaminants can reach the friction surfaces of moving parts, accelerating wear and reducing the engine's lifespan.

What is the ground clearance of the Enclave?

The Enclave has a ground clearance of 180mm. The ground clearance of a vehicle refers to the minimum distance between the lowest point of the vehicle (excluding the wheels) and the supporting surface when the vehicle is fully loaded and stationary. Below is an explanation of minimum ground clearance: 1. Minimum ground clearance must consider the passability of loading and unloading platforms during transport, as well as the possibility of avoiding scraping when the vehicle is near the edge of a typical sidewalk. If the vehicle is intended for sale in a specific country or region, local road conditions must also be considered. Additionally, the value of minimum ground clearance has certain limitations, as it is related to the vehicle's function and aerodynamics. For example, sports cars generally have a smaller minimum ground clearance, while SUVs have a larger one. 2. The smaller the ground clearance, the poorer the ability to overcome obstacles. Sedans typically travel on flat urban roads, so they have smaller ground clearance. Off-road vehicles have larger minimum ground clearance to allow them to overcome larger obstacles. Regarding minimum ground clearance, previous standards specified it to be around 150–160mm, but current standards have removed this mandatory requirement.

How to Quickly Improve Driving Skills?

Improving car driving skills is also a process of practice makes perfect. Here are some methods to enhance driving skills: 1. Prioritize driving techniques to overcome driving fears. The biggest advantage for beginners is the absence of bad driving habits, so it's important to pay attention to standardized operations and behaviors from the very beginning, gradually developing good driving habits. For new drivers, practice should progress from simple to complex and from familiar roads to unfamiliar ones. 2. Learn more driving techniques through the internet. What beginners fear most is 'short-sightedness,' meaning not looking far enough ahead and having a narrow field of vision. It's crucial to look further and broader, as it helps us observe the movements of other vehicles, pedestrians, and road conditions at all times. 3. Driving mindset mainly depends on oneself. The driving techniques learned in driving school only teach you how to start the car, which is completely different from driving on your own. Therefore, if possible, it's best to have an experienced driver guide you, as you can quickly learn a lot, which is very helpful for rapidly improving driving skills.

What to Do When the Engine Stalls After Warming Up?

Engine stalling after warming up is most likely due to a faulty fuel pump or a weak battery. There are two common scenarios for engine stalling after warming up: 1. The engine stalls automatically at idle. If the engine stalls at idle, it is often caused by issues with the throttle body or idle control valve. Severe carbon buildup or component damage in the throttle body/idle control valve can trigger this fault, with insufficient air intake being the primary cause. 2. The engine can maintain idle but stalls when the throttle is pressed. In this case, components of the intake system, such as the throttle body and idle control valve, should be checked first. Additionally, the fuel system must be considered, including whether the fuel pump is damaged, the fuel lines are clear, the fuel injectors are clogged, or the fuel pressure is normal. This issue could also be caused by problems with the spark plugs or ignition coils. Poor spark plug performance or a damaged ignition coil can be diagnosed through a spark test, but this should be performed by a professional—avoid attempting to fix it yourself.

What are the components of automotive antifreeze?

The main components of antifreeze are 50% pure water, 40% methanol, and 10% other substances. Functions of antifreeze: Antifreeze is a coolant containing special additives, primarily used in liquid-cooled engine cooling systems. It possesses excellent properties such as preventing freezing in winter, boiling in summer, and offering year-round protection against scale and corrosion. Antifreeze replacement cycle: For vehicles that operate for extended periods, such as taxis, high-quality antifreeze should generally be replaced annually. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which reduces the heat exchange efficiency between the antifreeze and engine components, ensure the product is within its validity period when adding it. Long-lasting antifreeze can remain effective for up to three years. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, it should be replaced promptly, and the system should be cleaned. Can different antifreeze brands be mixed? It is necessary to use the same brand of antifreeze. Different brands may have varying production formulas, and mixing them could lead to chemical reactions between the additives, rendering them ineffective.
