Running the AC in traffic can easily lead to carbon monoxide poisoning. Consequences of idling: Prolonged idling of the engine can easily cause carbon buildup in the engine. Over time, this may result in black smoke emissions and increased fuel consumption. If the engine idles for an extended period, the carbon monoxide it produces can accumulate and enter the vehicle, leading to carbon monoxide poisoning for the occupants. Precautions when using the AC: Therefore, maintenance professionals suggest that if you're waiting for someone for less than 5 minutes, you can stay in the car. However, if the wait exceeds 5 minutes, it's better to drive to an underground parking lot or a shaded area, turn off the engine, and step out of the vehicle. During midday hours, some drivers may feel drowsy and choose to rest in the car with the AC running—this is highly dangerous. Every summer and winter in China, multiple cases of carbon monoxide poisoning or suffocation deaths occur in vehicles with the AC on.

Can the license plate be retained when transferring vehicle ownership?

Can the license plate be retained when transferring vehicle ownership? The following is relevant information about vehicle transfer: Meaning of transfer: Vehicle transfer refers to changing the name of the vehicle owner.

What do the letters on car tires represent in terms of speed?

Tire letters such as J represent 100km/h, K represents 110km/h, etc. Here's an introduction to tire-related information: Introduction to tire letter grades: The letter Y refers to the tire speed rating, indicating the maximum speed the tire can withstand under specified conditions. Different tires have different letters representing their speed ratings engraved on the sidewalls, with the letter range spanning from A to Z. Tire replacement standards: Rubber has a certain service life. Under normal circumstances, car tires have a service life of about 3-5 years because tires are exposed to wind, sun, and rain for long periods, causing the rubber to gradually age. Aged tires have reduced strength, so when tires reach their service life, they should be replaced promptly.

What are the Differences Between Good and Bad Brake Fluid?

Brake fluid quality differences can be identified in terms of taste and condition. Below is relevant information about brake fluid: Function of Brake Fluid: Brake fluid, also known as brake hydraulic fluid or mineral oil brake fluid, possesses properties such as oxidation stability, anti-foaming, anti-rubber swelling, and anti-rust. Its replacement cycle is related to the vehicle's braking system and braking conditions during driving. Brake fluid has hygroscopic characteristics, and if not replaced for an extended period, the safety factor of driving will decrease. Brake Fluid Replacement Cycle: For vehicles used frequently, brake fluid should be replaced approximately every 30,000 kilometers. If the vehicle is used less frequently, the replacement interval can be extended accordingly, generally around 50,000 to 60,000 kilometers.

What Causes the Car to Shake and the Malfunction Light to Illuminate?

Car shaking with the engine malfunction indicator light on may be caused by engine misfire, excessive carbon buildup in the intake system, or issues in the ignition system. More information about the malfunction light is as follows: 1. If after the malfunction indicator light comes on, the car drives without any abnormal sensations, and acceleration and braking are all normal, then the vehicle can currently be driven normally. It could be that a certain sensor has malfunctioned but has now returned to normal. It may also be due to interference from certain external conditions, where this malfunction does not affect the vehicle's operation but may have some impact on emissions. In this case, you can temporarily continue driving and then go to a repair shop for inspection. 2. If after the malfunction indicator light comes on, the vehicle indeed has abnormalities, such as severe shaking, lack of power during acceleration, etc. In this situation, do not continue driving; request emergency towing service.

What is the Difference Between a Power Sunroof and a Panoramic Sunroof?

Power sunroofs and panoramic sunroofs differ in terms of area coverage and manufacturing costs. Below is a detailed comparison between the two: Difference in Area Coverage: Panoramic sunroofs are larger than power sunroofs, covering about two-thirds of the roof. However, some panoramic sunroofs cannot be opened, while others can open up to only half of their area. Power sunroofs cover approximately one-third of the roof and are operated by an electric motor. Pressing the switch button automatically opens the sunroof, and it can be stopped at any desired position. Difference in Manufacturing Costs: Due to their larger size, panoramic sunroofs have relatively higher manufacturing costs. In contrast, power sunroofs, being smaller in size, have relatively lower manufacturing costs.

What kind of engine oil should be used for the 1.5T Ford Kuga?

5W-20 is the recommended engine oil type for the 1.5T Ford Kuga, and it is best to use fully synthetic oil. Since the 1.5T Kuga is equipped with a turbocharged engine, the turbocharger operates under high temperatures and high speeds. Without fully synthetic oil, the engine may not receive adequate protection, leading to potential damage and reduced engine lifespan. The viscosity of engine oil changes with temperature, so it is crucial to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity. 5W means the oil can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the vehicle. The second number represents the oil's kinematic viscosity at 100°C. A higher value indicates better viscosity retention at high temperatures, which can also be understood as improved lubrication performance under high-temperature conditions. The method for changing the oil in the Chevrolet Orlando is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back into the oil pan. Use a wrench to loosen the oil drain plug and place an oil pan underneath to collect the old oil until it stops flowing. Start the engine and let it run for 30 seconds to allow the oil in the main oil passages to drain out. Use a specialized wrench to remove the oil filter. Apply a thin layer of oil to the gasket of the new oil filter and tighten it clockwise by hand. Add the new oil through the oil filler cap on the engine's valve cover, typically filling up to three-quarters of the oil container. Start the engine and let it run for 5 minutes, checking for any leaks around the oil drain plug and oil filter. If leaks are found, perform necessary repairs. After stopping the engine, pull out the dipstick to ensure the oil level is within the standard range.
