The reasons for the squeaking noise when the car air conditioner is turned on are as follows: 1. Refrigerant moisture causing squeaking: Abnormal noises inside the air conditioner are often caused by moisture or air in the system refrigerant, which can be appropriately released. The compressor has high requirements for the electromagnetic clutch. Moreover, the electromagnetic clutch is installed close to the ground and frequently comes into contact with rainwater and mud. When the bearing in the electromagnetic clutch fails, it can produce abnormal noises. 2. Compressor drive belt: The tension of the compressor drive belt may also cause abnormal noises from the car air conditioner compressor. If the drive belt is too tight, the load on the electromagnetic clutch will increase.

What is the purpose of the S gear?

S gear is the sport mode, which allows for faster acceleration. S gear is the sport mode of a car, where the transmission can shift freely but the shifting timing is delayed, keeping the engine at high RPM for a longer period. This enables the car to travel at low gear and high RPM for an extended time, resulting in greater torque output and acceleration. Here are some tips for using S gear: 1. Generally, when overtaking, you can shift into S gear to enhance acceleration. Engaging S gear can increase the engine load in a short time. However, S gear only delays upshifting without changing other operational aspects, which inevitably increases the transmission load in the short term, raises temperature, and accelerates wear. Therefore, try to avoid using S gear for extended periods. 2. In terms of fuel consumption, because the fuel injection volume increases at high RPM, the fuel consumption in S gear mode is higher than in normal mode. During vehicle start-up, high-speed cruising, and coasting, avoid shifting into S gear. Even if you do, it won't provide good results and will only increase fuel consumption. 3. Using S gear also has benefits for the vehicle. Cars that frequently drive in congested urban areas tend to accumulate more carbon deposits in the engine. Therefore, using S gear appropriately and periodically helps remove carbon deposits from the engine, improves fuel economy, and extends engine life.

Where is the main relay of Lavida located?

Lavida's main relay is located in the dashboard below the left side of the driver's seat. The automotive relay is an assembly composed of two parts: a control circuit that operates by a coil and a main circuit that operates by contacts. In the control circuit of the relay, there is only a relatively small operating current. This is because the contact capacity of the operating switch is small and cannot be used to directly control loads with higher power consumption; it can only control the on/off through the relay's contacts. Lavida is the first independently developed A-segment car by Shanghai Volkswagen. The interior design of this car is more sporty, and the black and silver color scheme is also very eye-catching. The multifunction buttons on the steering wheel are consistent with Volkswagen's usual settings, with the left side for volume adjustment and the right side for menu and Bluetooth phone controls.
