What does the 4S in a 4S store mean?

It refers to a four-in-one automobile sales department, which includes vehicle sales channels, retail parts sales, vehicle after-sales service, and comprehensive information feedback. The full name is Automobile Sales Service 4S Store, which emerged in 1998 and originated in Europe, offering relatively comprehensive services and strict management. Below is an introduction to 4S stores: 1. Business scope of 4S stores: In a region, there will be several 4S stores for a brand, mainly determined by the scale of the city. There is competition among each 4S store, even though they belong to the same brand. According to the current situation in China, standard 4S stores only exist in cities and above, while some county-level cities do not have automobile 4S stores. 2. Characteristics of 4S stores: They are established according to the manufacturer's unified standards, follow a uniform model, and are authorized by the manufacturer to sell only a single brand of vehicles. Within the price range allowed by the manufacturer, they attract customers with the lowest possible prices, reflect the brand's related value, and maintain the brand's reputation. However, it is important to correctly understand that 4S stores should not be regarded as automobile manufacturers.

Can you turn right when the straight arrow is red?

No. For arrow traffic lights, you can only turn right when the right-turn arrow is green, and you must be in the right-turn lane to do so. If you are in the straight lane, you cannot turn right regardless of whether the straight arrow is red or green. Below is some relevant information about turning at straight arrow signals: 1. Motor vehicle signals and non-motor vehicle signals: At intersections without non-motor vehicle signals or pedestrian crossing signals, non-motor vehicles and pedestrians should follow the motor vehicle signals. When the light is red, right-turning vehicles may proceed if they do not hinder the passage of released vehicles or pedestrians. 2. Right-turn lane signal settings at intersections: When the signal is a circular light, if there is no 'No right turn on red' sign at the intersection, you may turn right; if there is such a sign, right turns are prohibited. Check if there is a 'No right turn' sign at the intersection—if there is, you cannot turn right; if not, you may turn right. When the arrow is red, if there is a right-turn arrow signal, you can determine whether a right turn is allowed based on the color of the right-turn arrow light.

How Does the Automotive Air Conditioning System Work?

Here is a detailed introduction to the working process of automotive air conditioning: 1. Compression process: The compressor draws in low-temperature, low-pressure refrigerant gas from the evaporator outlet and compresses it into high-temperature, high-pressure gas, which is then discharged from the compressor. 2. Heat dissipation process: The high-temperature, high-pressure superheated refrigerant gas enters the condenser, where it condenses into a liquid due to the reduction in pressure and temperature, releasing a significant amount of heat. 3. Throttling process: The refrigerant liquid, which is at a higher temperature and pressure, passes through the expansion device, causing its volume to increase and its pressure and temperature to drop sharply, exiting the expansion device as a mist (fine droplets). 4. Heat absorption process: The mist-like refrigerant liquid enters the evaporator. Since the boiling point of the refrigerant is much lower than the temperature inside the evaporator, the refrigerant liquid evaporates into a gas. During the evaporation process, it absorbs a large amount of surrounding heat, and the low-temperature, low-pressure refrigerant vapor then re-enters the compressor.

How many kilometers should the Vios brake discs be replaced?

Vios brake pads need to be replaced approximately every 30,000 to 60,000 kilometers, and the replacement cycle varies depending on driving habits. The steps for replacing brake pads are as follows: 1. Before replacing the brake pads, open the cover of the brake fluid reservoir in the engine compartment to check the brake fluid level; 2. Prepare the new brake pads to be replaced and remove the wheel where the brake is located. Be careful to avoid scratching the rim during the removal process; 3. Use a wrench with a socket to remove the bolts of the brake caliper, then take out the brake pads. Check if the brake pads are excessively worn or cracked. If so, proceed to the next step of replacement; 4. Since the brake caliper may accumulate a lot of sand or dirt, clean it thoroughly with a cloth and apply anti-noise paste to prevent abnormal noises during braking; 5. Use a piston press to push the piston to its limit, then install the new brake pads onto the brake caliper. After installing the new brake pads, tighten the guide bolts to complete the installation; 6. After installation, cover the reservoir cap, get into the car, and press the brake pedal several times to reset the brake. Then check the brake fluid level to ensure it is within the appropriate range; 7. After replacement, test drive the car to check if the braking effect is achieved.

What Causes Abnormal Noises from the Chassis After Parking?

There are many reasons for abnormal noises from the chassis after parking a car. Below is a detailed analysis of the specific causes of abnormal noises from the chassis after parking: 1. Cooling noise from the catalytic converter: The normal operating temperature of the catalytic converter is 400-800°C. After the engine is turned off, its operation gradually stops, and the temperature decreases, causing the internal metal components to expand and contract due to heat, resulting in abnormal noises. 2. Cooling noise from the exhaust pipe: Typically, the exhaust pipe reaches temperatures above 200°C during cold idle. When the car is under high load or there is combustion of the air-fuel mixture in the exhaust pipe, the temperature can be even higher. Therefore, the exhaust pipe also undergoes thermal expansion and contraction, producing abnormal noises, often originating from the front end of the exhaust pipe and the flexible joint. 3. Cooling noise from the turbocharger: Under normal conditions, the exhaust gas temperature can reach 700°C, accelerating the friction-generated heat from the turbocharger's rapid rotation. After the engine is turned off, the thermal expansion and contraction are quite noticeable, leading to abnormal noises.

What Causes the Hissing Sound When Braking?

The reasons for abnormal brake noises are: 1. Rust on brake discs or pads: After prolonged parking, especially in humid weather or after rain, rust or dirt may form on the brake discs or pads. This issue can be addressed by applying butter or specialized lubricant to the connection between the brake pads and calipers. 2. New brake pads: New cars may produce similar noises when braking. New brake pads and discs require a break-in period, and such noises during braking are completely normal. 3. Excessive wear on brake discs or pads: Both brake discs and pads are high-wear components that experience friction with every brake application. Over time, wear naturally occurs, and excessive wear will lead to abnormal noises. Therefore, regular inspection and replacement are necessary. Typically, brake pads should be replaced every 60,000-80,000 kilometers, while brake discs should be replaced every 100,000-120,000 kilometers. 4. Installation issues: If the brake pads are installed incorrectly or are of the wrong model, abnormal noises may occur. Reinstalling the brake pads is recommended, and car owners should have this done at a professional auto repair shop.
