Passing through ETC scans the device. The onboard electronic tag installed on the vehicle's windshield communicates with the microwave antenna in the ETC lane of the toll station via dedicated short-range communication. This process utilizes computer networking technology to perform backend settlement processing with the bank, allowing vehicles to pass through highway or bridge toll stations without stopping while still paying the required fees. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Promotes low-carbon travel by reducing noise and exhaust emissions as vehicles pass through toll stations without stopping, thereby minimizing pollution; Reduced wear and tear: Saves costs by decreasing the frequency of vehicle starts and brakes, lowering wear and fuel consumption. Users also enjoy a 5% discount on toll fees; Improved efficiency: Theoretically, ETC lanes can increase vehicle passing efficiency by 2-3 times, making traditional ETC systems more updated, faster, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous.

What does it mean when the yellow light of the one-button start keeps flashing?

If the yellow light of the Roewe one-button start keeps flashing, it may be due to affected wiring contacts, a weak car battery, key sensing issues, or a locked steering wheel. The specific reasons for the flashing yellow light are as follows: Wiring Contact Issues: It could be caused by the installation of a dashcam or other electrical devices affecting the contact of other wiring, leading to the yellow light flashing. First, check the wiring and try reconnecting it. Weak Battery: If the car battery is weak, it may also cause issues with the one-button start. In this case, replacing the battery is a better option. Key Sensing Issues: If there is a strong magnetic field nearby, it can interfere with electronic devices, making it impossible to detect the key. You can point the key directly at the one-button start or quickly move away from the area. Locked Steering Wheel: A locked steering wheel is a normal anti-theft feature. This occurs when the steering wheel is turned after the car is turned off, causing the car's computer to assume a theft situation and automatically activate the anti-theft function. First, press the one-button start once, then step on the brake, turn the steering wheel, and press the one-button start again.

Are all new energy vehicles automatic transmission?

All currently available electric vehicles have only one forward gear. Therefore, there is no distinction between manual and automatic transmissions in electric vehicles. Here is more information about new energy vehicles: 1. Structure: Taking pure electric vehicles as an example in terms of vehicle construction, pure electric vehicles use three electric systems as the power source, and there is no transmission in the power structure. 2. Working principle: In terms of power generation during operation, pure electric vehicles provide electrical energy from the battery to the motor, which drives the motor to operate and thus propels the vehicle forward.

What are the causes of transmission limp mode failure?

The causes of transmission limp mode failure include computer transmission issues, errors in vehicle boost pressure deviation, problems with the vehicle's wiring system, and battery acid leakage. There is no need to worry or feel stressed when limp mode occurs; it indicates that the vehicle requires a thorough inspection and comprehensive repairs where issues are identified. Below is an introduction to transmissions: 1. Classification of transmissions: Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions consist of gears and shafts, while automatic transmissions are composed of components such as torque converters and planetary gears. 2. Development and reform of transmissions: With the continuous development of the automotive industry, transmissions have evolved from manual transmissions in the past to automatic transmissions today. Transmissions allow the vehicle to move in reverse without changing the engine's rotation direction, and shifting to neutral can interrupt power transmission for engine starting and gear shifting. Owners using automatic transmissions can easily operate their vehicles, and compared to manual transmissions, automatic transmissions are less prone to malfunctions.

What is the difference between registering a car in a different location and locally?

There is no difference in the license plates themselves between registering a car in a different location and locally. However, buying a car locally and registering it with an out-of-town license plate may have several impacts: the annual inspection may be more troublesome; there may be some inconveniences when traveling, such as traffic restrictions—local license plates have fewer restrictions while out-of-town plates have more; sometimes, traffic violation handling may need to be done at the registration location. Below is additional information: 1. Provide relevant materials: After purchasing a car in a different location, you need to ensure that the materials provided by the 4S store are complete, such as the car invoice, vehicle certification, maintenance manual, etc. These items are essential, and if the 4S store fails to provide any one of them, it will affect the subsequent registration and maintenance of the new car. 2. The vehicle must have a formal invoice, certification, purchase tax, and compulsory insurance. Any new car purchased from a formal car trading market nationwide can be registered at the place of residence. Compulsory insurance can be purchased at the 4S store, and other commercial insurance can be purchased in two ways: the first is to purchase insurance at the point of purchase, but be sure to choose a large insurance company that can provide coverage and claims nationwide.

Will the 4S store provide any compensation if a new car rusts?

Currently, there are no relevant regulations stipulating compensation for such situations. However, if this issue occurs with a new car, compensation can generally be negotiated with the 4S store. Below are the reasons for car rusting: 1. Humid environment: If the vehicle is submerged in water for a long time, it may affect performance at best or cause rust and decay at worst. 2. Design flaws of the vehicle itself: Incomplete structural design during the design phase, such as sharp corners or dead angles in the sheet metal, may lead to insufficient electrocoating of the car body. Alternatively, inadequate consideration in the process design may result in incomplete and comprehensive electrocoating and wax injection processes for the sheet metal.

Can a driving license be reissued by proxy?

Yes, it can be reissued by proxy. If a driver accidentally loses the "Motor Vehicle Driving License", they can bring their ID card, vehicle property certificate, etc., to the vehicle management office at the registration location, fill out an application form, and submit proof of identity to apply for a replacement. If authorizing someone else, the authorized person's ID card and a power of attorney from the authorizer are also required. After the vehicle management office accepts the application, the driving license can usually be reissued within one day. Below is more information about the driving license: 1. Introduction: The Motor Vehicle Driving License is a legal document that permits a motor vehicle to drive on roads within China. The driving license consists of three parts: the license holder, the main page, and the supplementary page. The front of the main page is the signed certificate core, and the back is a photo of the motor vehicle, sealed with a plastic cover. The supplementary page is the signed certificate core. 2. Function: The driving license verification system can verify and compare the authenticity of motor vehicles, query motor vehicle information, and provide travel safety guarantees.
