How Often Should the Cabin Air Filter Be Replaced Normally?

Generally speaking, the car's engine air filter should be replaced approximately every 15,000 kilometers driven, while the cabin air filter should be replaced every 10,000 to 20,000 kilometers or about once a year. However, the specific replacement interval should be determined based on the vehicle's usage conditions, driving environment, and air quality. More information about the air filter is as follows: 1. Location of the car's air filter: The air filter, fully named as the air filter element, is located on the side of the engine under the hood. Some air filters are cylindrical in shape and are also referred to as air filter cartridges. 2. Function of the car's air filter: It is used to filter the air entering the engine, removing dust particles from the air, and providing clean air to the engine's combustion chamber, primarily to protect the engine.

What Does the Exclamation Mark Symbol on the Dashboard Mean?

Here is a detailed explanation of the reasons why an exclamation mark symbol appears on the car dashboard: 1. A triangle with an exclamation mark in the middle may light up under the following circumstances: (1) Overheating of the dry dual-clutch transmission clutch. (2) Fuel cut-off system intervention or malfunction. (3) Parking sensor failure. (4) External light failure. 2. A circle with parentheses and an exclamation mark in the middle may light up under the following circumstances: (1) The light turns on for a few seconds after turning on the ignition and turns off after starting the engine. (2) It lights up when the handbrake is pulled up and turns off when released. (3) Low brake fluid level, lighting up while driving. (4) Brake system malfunction, causing the light to illuminate.

What items are generally included in a minor car maintenance service?

Minor maintenance primarily involves changing the engine oil and oil filter. Below is a detailed introduction to car maintenance items: 1. Engine oil and oil filter replacement: This mainly pertains to the lubrication system's maintenance. The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the oil, ensuring the lubrication system operates normally. The oil filter should be replaced along with the oil during an oil change. Under normal circumstances, a car should undergo maintenance every 5,000 kilometers. 2. Filter element replacement: The air filter's function is to filter air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The gasoline filter is typically replaced after driving 20,000-25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission oil, the battery, the throttle, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, with maintenance performed as needed based on usage conditions.

What does the auto switch of solar lights mean?

The auto switch for car lights refers to the automatic headlights. The headlights will automatically turn on or off based on the light sensing system. It can achieve automatic activation or deactivation, as well as automatic switching between high and low beams. Below is relevant information about automatic headlights: Function of automatic headlights: The headlights automatically turn on when the light dims and turn off when the light brightens. They can also automatically switch between high and low beams during encounters with other vehicles. After rotating the light switch to this position, for example, when passing through tunnels, on cloudy days, or in any dimly lit areas, the headlights will automatically illuminate and turn off once sufficient light conditions are met. When the light dims while driving, the headlights will automatically turn on, and they will turn off when the light brightens. Many people mistakenly believe that "automatic headlights" are specifically designed for tunnels, but this is not the case. The activation of automatic headlights has a delay—it takes about ten seconds after the light sensing system detects dimming before the headlights turn on. According to traffic regulations, headlights must be turned on before entering a tunnel, so manual activation is still required when passing through tunnels. Working principle of automatic headlights: Through photosensitive sensors, voltage signals are generated in response to changes in external light and fed back to the automatic headlight control module. After data analysis, the system determines whether the lights should be turned on.

What is the problem when the front wheels of a car make a creaking sound?

Possible causes: 1. The shock absorber itself is leaking oil or bent, etc., and can be directly replaced. 2. The shock absorber pressure bearing is aged or abnormally worn, and can be directly replaced or lubricated. 3. The shock absorber spring is deformed and can be directly replaced. 4. It could also be the wheel bearing making noise, which can be directly replaced. Methods to check shock absorber faults: 1. First, look: check if the shock absorber is leaking oil. Look directly at the shock absorber housing or dust cover when it's not raining or the car hasn't been washed. It's very intuitive and can be seen at a glance. 2. Also, listen: when driving at low speed, there is a dull sound when the wheels pass over bumps or slight vibrations on the road. The abnormal sound of the shock absorber is different from other chassis noises, it's very muffled. If it's the front shock absorber, there will also be obvious vibration felt on the steering wheel.

What Causes the Noise When Turning at Low Speed?

Here are the specific reasons for the noise when turning at low speed: 1. Turn signal return sound: When turning on the turn signal while turning, it may be caused by the rebound clip of the automatic turn signal return mechanism, which is a normal situation. 2. Noise from the steering column dust cover: If the noise comes from below the steering wheel, it may be from the steering column dust cover. Due to insufficient lubrication of the dust cover, friction noise occurs. Applying some butter inside the dust cover can solve the issue. 3. Noise from the steering wheel: This may be caused by the airbag clock spring inside the steering wheel. Remove the steering wheel airbag clock spring and apply butter to resolve it. Note: Disconnect the airbag fuse before removing the steering wheel to prevent the airbag from deploying. 4. Noise from the stabilizer bar: Check if the stabilizer bar bushings are loose or damaged. Loose or damaged stabilizer bar bushings not only cause noise when turning but also produce sounds when driving on uneven roads. Loose stabilizer bar bushings can be fixed by adding shims.
