Where is the rear radar buzzer of the Superb located?

The rear radar buzzer of the Superb is located near the rear roof lighting. Buzzer composition: The piezoelectric buzzer mainly consists of a multivibrator, piezoelectric buzzer disc, impedance matcher, resonance box, and housing. Some piezoelectric buzzers also have light-emitting diodes installed on the housing. Buzzer principle: It operates based on the piezoelectric effect principle. When an alternating voltage is applied, it generates mechanical vibrations; conversely, when mechanical force is applied, it also produces voltage signals. Therefore, the piezoelectric ceramic buzzer disc can be adapted for use as a vibration sensor. The voltage signal generated by the piezoelectric ceramic buzzer disc under mechanical force is very weak, so a voltage amplifier is generally required when used as a vibration sensor.

What should be paid attention to when doing the first car maintenance?

Driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's driving license; vehicle's purchase invoice are all the things needed for the first car maintenance. The first maintenance is carried out after driving about 5,000 kilometers, which refers to the first maintenance after the vehicle is driven. The precautions are: make an appointment with the 4S shop in advance. The first maintenance refers to the first maintenance after the new car is driven, and the specific time varies from car to car. The first maintenance is carried out after driving about 5,000 kilometers. The car needs to participate in the first maintenance in time, neither in advance nor delayed. The realization of the first maintenance marks that the running-in period of the car has now ended, and it can be driven according to the standard load and normal speed required by the car. The time of the first car insurance is calculated according to the date of picking up the car. There are two indicator values for the first maintenance time: mileage and time. See which comes first, the first is the standard. The first maintenance items include: changing the engine oil, oil filter, cleaning the air filter, checking whether various oil levels are normal, checking whether the generator belt and wiper blades are damaged, checking whether the tire pressure is normal, checking whether the tires are damaged, bulging, etc. Time required: It takes about 2 hours to complete all the work. The most important thing for the first maintenance of a new car is to change the engine oil and oil filter. When changing the engine oil, the oil filter element must be replaced together. When choosing the engine oil, you must refer to the "Model Use and Maintenance Manual", and different models have different regulations on the engine oil label. Maintenance precautions: Do not rinse the inside of the car body with water: Many people will arrange and clean the car by themselves during the holidays, and rinse with water and scrub with a cloth. Here, it needs to be reminded that the inside of the car body does not need to be rinsed directly with water. If the floor mat is dirty, you can use a vacuum cleaner, or take it out, brush and wash it with detergent, dry it, and then put it back. There are many through holes in the grooves under the rubber mats on the floor of the cab. After the water enters, it will not dry by wind, but will flow to the gearbox and other parts through the through holes for erosion and corrosion. The good practice is to clean with a vacuum cleaner and then scrub with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is in short supply, it is recommended that you release the antifreeze as soon as possible and add the same brand of antifreeze from the beginning. Because the brands of antifreeze are different, their chemical functions are also very different. Various functional preservatives will corrode other functional preservatives. Different brands of antifreeze use different preservatives. Do not mix them to avoid unnecessary trouble. Do not lubricate the tire bolts and nuts: When the bolts of the running car are rusty, they are usually oiled so that they can work normally again. In order to prevent the bolts and nuts on the wheels from rusting, some people apply lubricating oil to the bolts and nuts, but it brings necessary risks to safe driving. When the car is running at high speed, the bolts and nuts are simply lifted or even dropped, resulting in driving failure. When the fuel injection car is promoted, there is no need to step on the accelerator: The promoter of the fuel injection car is different from that of ordinary cars. Its fuel injection control device can actively adjust the fuel supply according to the temperature and working conditions of the promoter, so that the promoter can be promoted smoothly.

What are the causes and solutions for abnormal engine belt noise?

Here are the causes of abnormal engine belt noise: 1. Mostly caused by aging of various belt groups in the engine: or issues with the tensioner leading to overly loose belts, resulting in friction noise, belt slippage, etc. 2. Major belt groups and tensioners inside the engine: such as the engine timing belt, alternator belt, circulating water pump belt, air conditioning belt, power steering pump belt, etc. 3. Caused by the contact surfaces between the belt and pulley becoming too smooth. 4. When the engine speed changes rapidly. Here are methods to solve abnormal engine belt noise: 1. Check if the accessories driven by the belt have bearing damage, seizure, excessive play, or increased accessory power consumption. 2. Replace the belt, or lightly sand the contact surfaces between the pulley and belt with 100-grit sandpaper (light sanding is sufficient).

Can the Air Conditioning Be Turned On When the Car Is Powered On?

You can turn on the air conditioning when the car is powered on. Here are the details: Compressor Function: The air conditioning can be turned on without starting the engine, but the air blown out by the blower is just natural air. The air conditioning compressor is driven by the engine's power, so when the car is turned off, the compressor naturally stops working. The natural air blown by the blower is powered by the battery, and excessive use of the blower may drain the battery over time. This applies only to traditional fuel-powered vehicles. Interlock Mechanism: Modern cars are equipped with an interlock mechanism that automatically cuts off most auxiliary circuits when the engine is turned off, including the air conditioning and blower. Leaving the air conditioning on after turning off the engine can easily damage it. The next time you start the car, the load from the air conditioning may cause excessive strain on the engine, leading to potential damage.

How to cancel previous records when re-registering after the driving test has expired?

There is no remedy for an expired driver's license test, and there is no need to cancel the records at the vehicle management office. Here is the relevant information: 1. Regulations on the Application and Use of Motor Vehicle Driver's Licenses: According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses," candidates must pass Subject 1 to obtain a learning driving permit before they can proceed with the practice and tests for Subjects 2 and 3. The validity period of the learning driving permit is three years. If Subjects 2 and 3 are not completed within the specified time, the passed subject scores will be invalidated. 2. Automatic Cancellation: In the past, it was indeed necessary to personally visit the vehicle management office to cancel the student records if the driver's license test expired. However, the process has now been simplified. If all subject tests are not completed within three years of obtaining the learning driving permit, the system will automatically cancel the student's record information and clear the learning records.
