Does the Audi A3 have a glass heating function?

The Audi A3 has a rearview mirror heating function. Location of the rearview mirror heating: No need to manually adjust the angle; it is electric, usually controlled by buttons near the driver's seat, allowing adjustment of the rearview mirror's angle. The mirror can automatically heat up, drying water droplets or snow on the surface during rain or snow, ensuring clear visibility. Practical in winter: The heated rearview mirror is particularly useful in winter. On winter mornings, you may find frost on almost all the car's glass surfaces, which is difficult to wipe off with a towel. The rearview mirror heating function can help with this. Purpose of rearview mirror heating: The rearview mirror heating function mainly ensures clearer visibility of the rearview mirror, especially in foggy or rainy conditions. It is recommended to turn on the rearview mirror heating device to better observe the rear of the vehicle while driving, enhancing safety.

Is Vehicle Damage Insurance Mandatory?

Vehicle Damage Insurance falls under commercial insurance, and there is no legal requirement to purchase it. Auto insurance is divided into compulsory insurance and commercial insurance. Compulsory insurance is mandated by the state, while commercial insurance is optional based on personal preference. According to Article 2 of the 'Regulations on Compulsory Traffic Accident Liability Insurance for Motor Vehicles': Owners or managers of motor vehicles driven on roads within the territory of the People's Republic of China must purchase compulsory traffic accident liability insurance in accordance with the regulations. Below are the types of insurance required after purchasing a vehicle: 1. Compulsory Traffic Accident Liability Insurance (CTPL): This is a state-mandated insurance, and failure to purchase it may result in fines if caught by traffic police. The coverage is limited and primarily benefits third parties, not the policyholder's own vehicle. 2. Third-Party Liability Insurance: This covers losses due to bodily injury or death of third parties caused by the policyholder. It is essential for both personal and third-party protection. 3. Vehicle Damage Insurance: This compensates for losses to the policyholder's own vehicle due to natural disasters or accidents. It is recommended for new drivers. 4. No-Deductible Insurance: An add-on that transfers the policyholder's liability to the insurance company, reducing personal losses. If both Vehicle Damage Insurance and Third-Party Liability Insurance are purchased, it is advisable to also get No-Deductible Insurance.

What is the purpose of the supplementary page of a driver's license?

The supplementary page of a driver's license is a dedicated section for recording the license's file number and related information. Neither the main page nor the supplementary page of a driver's license is recognized if presented alone. Handling of missing supplementary page: A motor vehicle driver's license without the supplementary page is invalid, and similarly, having the supplementary page without the main page (original) is also invalid. Therefore, if you are checked while driving without the supplementary page, it is considered driving without a license, and your vehicle may be impounded along with other related penalties. Function of the file number on the supplementary page: The file number is essentially the ID number of the driver's license. Each driver's license has a unique file number, just as a person has a unique ID number. Through this number, one can not only verify which vehicle management office issued the license but also check the individual's demerit point status. The file number is typically a 12-digit serial code, where the first two digits represent the province code of the license, the third and fourth digits represent the city code, and the last eight digits are the sequential number assigned by the local vehicle management office.

Can items be placed on the dashboard?

Items can be placed on the dashboard, but care should be taken not to obstruct the driver's line of sight. Article 62, Section 2 of the 'Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China' states that drivers of motor vehicles shall not hang or place items within the front or rear window areas of the vehicle that obstruct the driver's view. Hanging decorations on the rearview mirror poses safety hazards. This behavior also violates Article 62, Section 2 of the 'Road Traffic Safety Law Implementation Regulations,' which prohibits hanging or placing items that obstruct the driver's view within the front or rear window areas of a motor vehicle. The violation code for this offense is 10490, and violators will be subject to fines. This applies not only to hanging decorations on the rearview mirror but also to placing decorations on the rear windshield. The so-called safe range refers to the size and height of the items hung or placed, which must not interfere with the driver's line of sight. Disadvantages of placing items: After placing decorations in the vehicle, if the vehicle brakes suddenly, items such as glasses, plastic figurines, etc., may fly around, not only obstructing the view but also potentially damaging the windshield, leading to unnecessary property losses.

Should Skyactiv-G engines use 92 or 95 octane gasoline?

According to the official vehicle owner's manual recommendation, Skyactiv-G engines should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the owner's manual, you can also find this information on the fuel filler cap. The fuel filler cap will clearly indicate the recommended octane rating. Traditionally, the gasoline grade could be determined by the engine's compression ratio: vehicles with compression ratios between 8.6-9.9 should use 92 octane, while those between 10.0-11.5 should use 95 octane. However, with modern technological advancements, compression ratio alone cannot determine the required gasoline grade - high compression ratio engines can still be tuned to use lower octane fuel. This is because other factors also come into play, such as ignition timing, turbocharging technology, and Atkinson cycle technology. Generally speaking, higher octane gasoline contains more octane and has better anti-knock properties. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If you occasionally use the wrong octane rating in a Skyactiv-G engine, simply switch back to the correct grade after consumption. However, long-term use of incorrect octane ratings may cause the following issues: For vehicles requiring lower octane: Using higher octane fuel won't cause damage, but the increased octane rating alters the fuel's ignition point, potentially causing delayed combustion. This reduces both engine power output and thermal efficiency, resulting in noticeably poorer performance; For vehicles requiring higher octane: Using lower octane fuel may cause engine knocking. The significantly lower octane rating lowers the fuel's ignition point, potentially causing premature ignition during the compression stroke. If combustion occurs before spark plug ignition during the compression stroke, resistance will occur during the upward stroke. This resistance makes engine operation very unstable. Mild knocking only increases noise without significant engine damage, but noticeable knocking indicates severe engine conditions - the vibrations not only affect driving stability but also cause abnormal wear on pistons and cylinders, potentially leading to cylinder scoring in severe cases.

Why does the Nissan Teana keyless entry fail after battery replacement?

The reason why the Nissan Teana keyless entry fails after battery replacement is either a dead battery or poor battery contact. Below are the specific reasons: Control module malfunction: Failure of the timing control module in the remote key can also cause the remote to stop working. Alternatively, aging of the vehicle's remote transmitter antenna can lead to this issue. In such cases, it's advisable to visit a repair station for inspection and repair. Remote signal interference: Additionally, some vehicles with explosion-proof sun films applied to the front windshield may experience unresponsive remote door locks when attempting to unlock from the front. This happens because the explosion-proof sun film partially blocks the remote signal. Remote key malfunction: After replacing the battery, the remote key needs to be re-matched. Insert the remote key, turn it to the "I" position, then quickly return it to the "0" position. Repeat this process four times, then swiftly remove the key. Press any button, such as the unlock button, for 4-5 seconds until you hear a sound from inside the car. The key coding is now complete.
