How to Turn on the High Beam in a Sylphy?

To activate the high beam in a Nissan Sylphy, first grasp the outermost left end of the lighting control lever located on the left side of the steering wheel. Rotate it clockwise by three notches to turn on the low beam, then push the lever forward to engage the high beam. Below are detailed explanations about high beams: 1. Difference between high and low beams: Both serve nighttime illumination functions, but high beams project light at a higher angle and longer distance, whereas low beams emit light at a lower angle and shorter range. 2. Hazards of improper high beam usage: Avoid using high beams in urban areas with good street lighting, as their elevated angle can dazzle oncoming drivers and pedestrians, posing significant safety risks. 3. Proper high beam applications: Flashing high beams alternately at night can substitute horn usage to alert nearby pedestrians and vehicles. High beams are suitable for highways or rural areas without streetlights but must be switched to low beams during oncoming traffic encounters.

Why Does the Car Make Loud Noise When Running the Air Conditioner at Low Speed?

There are several main reasons why a car makes loud noise when running the air conditioner at low speed: 1. The air conditioner filter is too dirty, causing excessive noise. 2. There are foreign objects in the blower fan blades. You can try turning on the blower without starting the engine to see if the noise occurs. If the noise appears, it proves the problem lies with the blower. 3. The car's air conditioner fan blades are deformed or the fan motor is damaged. 4. The clutch bearing inside the air conditioner pump is worn, causing the engine noise to increase when the air conditioner is on. This component cannot be replaced separately; the entire air conditioner pump assembly needs to be replaced. 5. Excessive refrigerant (Freon) content. If the refrigerant level is too high, the compressor's load will increase, leading to higher overall load. Check the air conditioner's sight glass: if liquid flows through the window with a few bubbles when the air conditioner is on, the refrigerant level is normal. If there are no bubbles or very few, it indicates an excessive amount.

Spark Plug Replacement Interval for Cars?

Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it is recommended to follow the vehicle's user manual. The following standards can be referenced for maintenance and replacement: Platinum spark plugs should be replaced at 40,000 kilometers, standard nickel alloy spark plugs at 20,000 kilometers, and iridium spark plugs at 60,000 to 80,000 kilometers. Methods to determine if a spark plug is damaged: Remove the spark plug and inspect its appearance to assess its condition. A normal spark plug will have an insulator skirt and electrodes that appear grayish-white, grayish-yellow, or light brown. A properly functioning spark plug will have a reddish-brown insulator skirt, an electrode gap between 0.8-0.9mm, and no signs of electrode burn. If the spark plug is covered in oil or deposits but not damaged, it can continue to be used after cleaning off the oil and deposits. If the spark plug is severely damaged—showing signs of blistering, black streaks, cracks, melted electrodes, etc.—the cause of the damage should be identified and the issue resolved before replacing the spark plug. Additionally, if the spark plug appears blackened as if smoked, it indicates the wrong heat range was selected, the air-fuel mixture is too rich, or engine oil is leaking into the combustion chamber.

What Do Engine Oil Codes Mean?

The meaning of engine oil codes is as follows: Engine oil codes are divided into two categories, one is the oil viscosity, and the other is the oil grade. (1) Viscosity index: Generally, the SAE standard is used as the international standard, which is what we commonly refer to as 5W-20, 5W-30. The specific meanings are: The first number represents the low-temperature viscosity index, indicating the minimum working temperature at which the oil can function. (2) Grade index: In China, the API standard is generally used, divided into API SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, SP; Those starting with the letter "C" represent oils for diesel engines, with specifications including: API CA, CB, CC, CD, CE, CF, CF-2, CF-4, CG-4, CH-4, CI-4. If both are present, such as SM/CF, it indicates that the oil is suitable for both gasoline and diesel engines. This involves the oil's quality, shelf life, impurity content, etc. The later the grade, the higher the level, the better the quality, and the more expensive it is. This is what is commonly referred to as the standard for full synthetic and semi-synthetic oils. Generally, oils before SL are mineral oils, SM is semi-synthetic oil, SN and above are full synthetic oils, with the current highest grade being SP. Additionally, the European ACEA (European Automobile Manufacturers' Association) has established another set of standards, which are more stringent.
