Audi's correct usage of internal and external air circulation is to use internal circulation in traffic jams and external circulation on highways. Here are the detailed instructions for using Audi's internal and external air circulation: 1. How to use internal circulation: Audi's internal circulation is used to prevent polluted air from entering the car. You can turn on the internal circulation when stuck in traffic or parked, because in the external circulation mode, wind-blown dust can easily enter the car, increasing the dust inside. 2. How to use external circulation: Audi's external circulation is used to replenish fresh air inside the car. Using external circulation allows you to breathe fresh air from outside. When driving at high speeds for long periods, the air inside the car can become stuffy, so you can use external circulation to let fresh air in.

When driving my Audi, I've found that the key to correctly using the recirculation and fresh air modes lies in switching them according to the situation. The recirculation mode makes the air conditioning circulate the air inside the car without drawing in external air, which is suitable for traffic jams or entering tunnels as it prevents inhaling exhaust fumes or unpleasant odors. To activate it, simply press the recirculation button (the icon resembling a person inside a car) on the center console after starting the car. The fresh air mode, on the other hand, introduces outside air and is ideal for highway driving or open roads, ensuring air circulation inside the car to prevent stuffiness and dizziness. Its icon is an arrow entering the car. On rainy or foggy days, switching to fresh air mode can defog the windows faster because the dry incoming air removes moisture quickly. However, avoid using only one mode for extended periods. For example, during pollen season, I use recirculation to prevent allergies, but I switch to fresh air for a few minutes during breaks to ventilate. Audi's automatic climate control makes this even smarter—pressing the AUTO button adjusts it automatically, but manual adjustments are also flexible, ensuring a comfortable and safe driving experience.

What is an Automotive Chip?

Automotive electronic chips are chips used in vehicles. Taking the car key chip as an example, here is a detailed introduction to car key chips: 1. Working Principle: A car key chip is a component that can receive and transmit pulse signals. When the car key is turned in the ignition switch, the engine control unit (ECU) in the vehicle sends an encrypted electronic code signal to the chip inside the car key. The vehicle will only start if the ECU unit receives the correct anti-theft code signal in response. 2. Function: Even without any buttons, a car key can activate and deactivate the vehicle's anti-theft system through the internal chip encoding. Programming a key with a chip requires specialized original equipment from the manufacturer.

Does a 7-speed dry DSG require transmission oil change?

7-speed dry DSG requires transmission oil change. Regardless of the type of transmission, the lubricating oil needs to be replaced during normal usage. The transmission oil should be changed after approximately 40,000 kilometers of use or about three years of operation. Transmission oil effectively protects the internal components of the transmission. Specific details are as follows: Methods for changing transmission oil: There are two methods for changing transmission oil. The first method is gravity oil change, and the second method is using a circulation machine for oil change. Both methods can effectively replace the transmission oil to achieve the ultimate purpose of use. Locations for transmission oil change: Transmission oil can be changed at local brand after-sales service departments or local repair shops. In addition to protecting the internal components of the transmission, transmission oil also helps reduce the temperature of the transmission.

How often should a motorcycle chain be cleaned?

Motorcycle chains should be cleaned every 2000 to 3000 kilometers. Below are specific details about motorcycle chains: 1. Function of the chain: The motorcycle chain is the connecting component between the transmission output gear and the drive wheel gear. If it is too loose, it cannot ensure the transmission ratio and power transfer. If it is too tight, it is prone to wear and breakage. If the chain is loose, it is best to promptly take it to a repair shop for inspection and replacement. 2. Effects of improper maintenance: If the chain is not maintained for a long time and the lubrication is poor, it will generate greater friction resistance during operation, which can also result in some loss of engine power. Long-term inefficient operation may also lead to chain loosening or even detachment. Therefore, regular maintenance involving cleaning and lubrication of the chain is necessary.

What are the features of the 2021 Sagitar Beyond Edition?

2021 Sagitar Beyond Edition features include engine start-stop switch, tire pressure monitoring, one-button start, safety lock, etc. Engine Start-Stop: After the vehicle starts, once the speed exceeds 3km/h (approximately 2mph) and lasts for about 4 seconds, the engine start-stop function will automatically activate. The benefit of this function is that through automatic engine start-stop, it can save fuel consumption and reduce vehicle exhaust emissions without changing the driver's driving habits. Tire Pressure Monitoring: The tire pressure monitoring system continuously monitors the tire pressure status of all four tires. If any tire pressure shows an abnormality, it will trigger an alarm. One-Button Start: The one-button start system is part of the smart car features, enabling a simplified start and shutdown process with a single button. Safety Lock: When triggered, it disables the window lift buttons on the rear doors, and the yellow indicator light in the button will illuminate.

Is a Wet Dual-Clutch Transmission Manual or Automatic?

Wet dual-clutch transmissions are automatic transmissions equipped with a manual mode. Below is a detailed introduction to dry and wet dual-clutch transmissions in automobiles: 1. Working Principle: The working principles of both types of transmissions are fundamentally the same, utilizing two clutches that operate alternately. The difference lies in the medium connecting the driving and driven plates. Wet dual-clutch transmissions primarily rely on oil, whereas dry dual-clutch transmissions mainly depend on air. 2. Basic Structure: In wet dual-clutch transmissions, the two sets of clutch plates are housed in a sealed oil chamber, with the transmission oil absorbing heat by immersing the clutch plates. In contrast, dry dual-clutch transmissions do not have a sealed oil chamber for the friction plates and rely on air cooling for heat dissipation.
