Does a new car come with underbody armor from the factory?

New cars do not come with underbody armor from the factory. Owners of newly purchased vehicles can decide whether to apply underbody armor based on their driving environment. If driving in environments with a lot of gravel or poor road conditions, it is recommended that owners apply underbody armor. If the owner primarily drives in urban areas, applying underbody armor is unnecessary. Most vehicles undergo anti-rust treatment for the underbody during the manufacturing process. Best time to apply underbody armor for a new car: The optimal time to apply underbody armor for a new car is when the vehicle has been driven approximately 60,000 kilometers. Since the underbody has protective measures from the factory, gravel encountered during driving will gradually weaken these protections. Additionally, the 60,000-kilometer mark is a major maintenance period for the vehicle, making it an ideal time for owners to apply underbody armor during this service to prevent rust. If the owner frequently drives on poor road conditions, underbody armor should be applied earlier. Function of underbody armor: Underbody armor helps protect the car's underbody during driving, preventing damage from road gravel and also reducing the risk of rust formation during vehicle use.

Where is the AUX interface of Audi Q7?

The AUX interface of Audi Q7 is located under the center console armrest. The AUX is an audio input interface. The basic working principle of the AUX interface is that after connecting to the AUX interface, the audio in electronic products can be connected to the car audio through the headphone jack and AUX interface, and the audio can be played in the car audio broadcasting facilities. The USB interface can be inserted into a USB flash drive to play audio. When using it, insert one end into the AUX interface and the other end into a video player such as a mobile phone, MP3, or MP4. In this way, you can listen to songs or niche music anytime and anywhere, not limited to car music CDs. However, if the playback device runs out of power, the music will also stop (the interface is generally a 3.5mm labeled headphone jack). Aux is the abbreviation of Auxiliary, which is an additional signal line design. In general audio equipment, in addition to the official output and input terminals, there are often several input and output terminals labeled Aux as backup connection terminals. When there are special applications, such as additional sound output or input, this type of terminal can be used. These backup terminals or lines, whether input or output, are collectively referred to as Aux. Function: The AUX port is an asynchronous port, mainly used for remote configuration, dial-up connection, and can also be connected to a MODEM through a transceiver. It supports hardware flow control. The AUX port and CONSOLE port are usually placed together because their respective applicable configuration environments are different. The AUX interface establishes a command-line connection between the user and the device, performing some operations that are usually impossible in user mode, such as initialization, restoring initial configuration, and correcting abnormal user modes. It provides a fixed port for the device, which can be used as a common asynchronous serial port with a maximum speed of 115200bit/s. Using the AUX interface, remote configuration of hardware products, line backup, and other functions can be achieved. Note: When using the AUX interface, pay attention to buying the correct connecting cable, and also be careful not to plug the audio cable into the wrong port. When using the AUX interface, it is best to follow the usage steps in the product's instruction manual. If you still don't know how, you can consult the product's official website or call for advice.

Can a new car be modified?

A new car cannot be modified before it is registered. Modifications alter the vehicle's appearance or performance, and if the original data does not match, the car cannot be registered. If you want to modify your car, you must wait until after obtaining the license plate and follow the "Motor Vehicle Registration Regulations" to avoid illegal modifications, which could lead to penalties such as fines from traffic police. Car modifications cannot be done arbitrarily. For example, changing the body color must not exceed 30% of the original color as per regulations. Enthusiasts of light modifications must not omit adding lenses. Interior modifications can be done freely as long as they do not affect safe driving. Installing navigation systems, dash cams, etc., is generally acceptable. Article 9 of the "Motor Vehicle Registration Regulations" stipulates that registration will not be granted under the following circumstances: 1. The proofs and certificates submitted by the vehicle owner are invalid. 2. The vehicle's origin certificate has been altered, or the owner listed on the origin certificate does not match the identity proof. 3. The proofs and certificates submitted by the vehicle owner do not match the vehicle. 4. The vehicle was produced without permission from the State Council's motor vehicle product authority or imported without permission from the national import authority. 5. The vehicle's technical data does not match the data announced by the State Council's motor vehicle product authority. 6. The vehicle's model, engine number, vehicle identification number, or other technical data do not comply with national safety technical standards. 7. The vehicle has reached the mandatory scrapping standard set by the state. 8. The vehicle has been legally seized or impounded by courts, procuratorates, or administrative law enforcement agencies. 9. The vehicle has been reported as stolen or robbed. 10. Other circumstances that do not comply with laws or administrative regulations.

What is the amortization period for cars?

Vehicles have a depreciation and amortization period of 4 years. Below is relevant information about motor vehicles: Definition: Motor vehicles are self-propelled by their own power devices, equipped with 2 or more wheels, do not require overhead lines or tracks, can operate on road or off-road surfaces, and are primarily used for transporting people, goods, or performing certain specialized tasks. China introduced automobiles in 1901, initially referred to as "automatic vehicles," and later simplified to "cars" due to gasoline engine propulsion. Classification: Vehicle classification is a fundamental aspect of various vehicle standard systems. Different standards have different classification methods, which may cross-reference each other while also having distinct focuses. Only by correctly understanding and grasping the basic concepts and applicable scopes of different classification methods, and clarifying the connotations and extensions of specific definitions, can one accurately apply relevant standard clauses in motor vehicle inspection practices, precisely determine vehicle types, and correctly issue inspection conclusions.

Can car maintenance be done at any 4S store?

Car maintenance can be done at any 4S store. When performing maintenance at repair shops, try to avoid involving too many items. For example, modern car electronic control systems are highly advanced. Many vehicles require specialized diagnostic computers to rematch after throttle body cleaning, otherwise issues like unstable idling may occur. Such specialized equipment is generally not available at ordinary repair shops. Therefore, maintenance items at repair shops should be kept relatively simple, and circuit-related maintenance should still be performed at 4S stores. Below are relevant details: Free first maintenance: The first maintenance of a car is free, which is provided by the manufacturer, not the 4S store. As long as the vehicle is within the warranty period, it can be serviced nationwide. The maintenance systems are interconnected, and maintenance records can be checked at any 4S store. Nationwide warranty: 4S stores are dealers and authorized service centers designated by the manufacturer. Before the first maintenance, as long as you have the first maintenance card, you only need to provide it for free maintenance, and the 4S store will take it back. The 4S store applies for subsidies from the manufacturer with the first maintenance card. Without it, you cannot enjoy free maintenance. The first maintenance can be done at any 4S store of the same brand, all of which offer free maintenance, even in other regions. All manufacturers provide nationwide warranty.
