What does the low coolant level warning mean?

Where can I see that the engine oil is low-ash?

Use C-series certified low-ash engine oil. Here are specific details about low-ash engine oil: 1. Introduction to low-ash: Low-ash is generated by the combustion of certain additives in engine oil. Some of these ash deposits accumulate inside the engine, forming what car enthusiasts commonly refer to as "carbon deposits." Therefore, you can simply consider low-ash engine oil as producing fewer carbon deposits. 2. Key points: It's important to note that the current engine oil market is quite mixed. Many sellers, in order to boost sales, will privately label their oil bottles with API SP-grade standards without actually obtaining the relevant certification. Therefore, when selecting low-ash engine oil, always purchase well-known brands and choose products that have official certification and can be verified on the official API website. This will effectively help you avoid counterfeit or substandard engine oil products.

Can Halogen Bulbs Be Replaced with LED Bulbs?

Halogen bulbs can be replaced with LED bulbs. The following are the benefits of replacing halogen bulbs with LED bulbs: 1. No radiation: LEDs use cold light sources, with minimal glare and no radiation, and do not produce harmful substances during use; 2. Energy-saving: LEDs operate at low voltage, use DC drive mode, and have ultra-low power consumption (0.03-0.06W per diode), with an electro-optical power conversion rate close to 100%. Under the same lighting effect, they save more than 80% energy compared to traditional light sources; 3. Recyclable: LEDs have better environmental benefits, with no ultraviolet or infrared rays in the spectrum. The waste is recyclable, pollution-free, and contains no mercury, making them safe to touch and a typical green lighting source.

How Often Should Volkswagen Spark Plugs Be Replaced?

Under normal conditions, Volkswagen's original spark plugs should be replaced every 20,000 to 30,000 kilometers. For iridium or platinum spark plugs, replacement can be done every 60,000 to 80,000 kilometers. Steps for replacing spark plugs: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one. While removing them, check for any external debris like leaves or dust and ensure they are thoroughly cleaned. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, and then use the socket to fully tighten it. Reinstall the high-voltage distributor wires in the correct firing order and secure the cover. Effects of faulty spark plugs: Damaged spark plugs can directly cause issues such as electrical leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The most significant problem is difficulty starting the engine, which affects normal vehicle operation. Severe spark plug erosion, blistering at the tip, damaged or melted electrodes, or burn marks indicate that the spark plug is damaged and should be replaced. Symptoms of faulty spark plugs in a car: Damaged spark plugs may lead to the following issues: difficulty starting, reduced power, excessive exhaust emissions, and increased fuel consumption.

Do Parallel Imported Vehicles Require Tariffs?

Parallel imported vehicles are subject to tariffs. Here are the specific advantages of parallel imported vehicles: 1. Price Advantage: Parallel imported vehicles eliminate many intermediate steps. Moreover, the pricing of parallel imported vehicles by dealers is not restricted by manufacturers, offering more flexibility. As a result, they often come with significant discounts, typically 10% to 20% lower than domestically produced models. 2. Model and Delivery Time Advantage: When new vehicles are launched overseas, they may not be immediately available in China due to strategic planning by automakers or domestic certification processes. However, as parallel imported vehicles, they can be freely purchased overseas and then shipped to China for sale, significantly reducing waiting times for new models. 3. More Diverse Models and Configurations: It allows purchasing overseas models not available in China. Generally, to align with China's market positioning strategy, automakers make certain adjustments or modifications when importing overseas models to China.

What are new energy vehicles called in Japan?

New energy vehicles are also referred to as new energy vehicles in Japan. These primarily include pure electric vehicles, while in China, new energy vehicles also encompass plug-in hybrid vehicles. Pure electric vehicles offer numerous advantages compared to internal combustion engine vehicles. They rely on electric motors to propel the vehicle forward, and the power output method of electric motors differs from that of conventional gasoline and diesel engines. Relevant information about automotive emission standards is as follows: 1. Introduction: Automotive emission standards refer to regulations on the content of harmful gases emitted from vehicle exhaust, such as CO (carbon monoxide), HC+NOx (hydrocarbons and nitrogen oxides), and PM (particulate matter, soot). 2. Implementation: Starting from January 1, 2004, Beijing upgraded its vehicle emission standards from Euro I to Euro II. By 2008, the Euro III standard was officially implemented.

What is the function of the steering gear?

The function of the steering gear is to appropriately transform the steering torque and steering angle from the steering wheel (mainly by reducing speed and increasing torque) and then output it to the steering linkage mechanism, thereby enabling the vehicle to turn. The following is a detailed introduction to the automotive power steering system: 1. Function: It uses the power generated by an electric motor to assist the driver in steering. This system directly provides steering assistance through an electric power motor, eliminating the need for components such as the power steering pump, hoses, hydraulic fluid, drive belt, and pulley mounted on the engine required by hydraulic power steering systems, saving energy and protecting the environment. 2. Composition: The automotive power steering system can improve vehicle stability. When the vehicle shows signs of instability, the electronic power steering system can independently brake each wheel and participate in the engine system management to ensure driving safety. The automotive power steering system mainly consists of a vehicle speed sensor, reduction mechanism, torque sensor, electric motor, and electronic control unit.
