Used cars from 4S stores can be purchased. The sources of used cars in 4S stores are mainly trade-in vehicles. The so-called trade-in vehicles refer to cars that owners exchange for new vehicles, offsetting some of the costs of the new car. These trade-in vehicles then become the used cars that 4S stores sell. Below is an extended introduction: Reliability: Relatively speaking, 4S stores provide a certain level of quality assurance for their car sources, making them slightly more trustworthy compared to other channels. Additionally, 4S stores usually offer services such as extended warranties. Selection: However, it is still essential to be cautious. Friends who are not knowledgeable about cars should be especially careful, and even those who understand cars must be prudent. It is best to seek help from trusted professionals to assist in selecting, identifying, and evaluating the vehicles.

What system does highway ETC refer to?

Highway ETC (Electronic Toll Collection) translates to electronic toll collection, which is a non-stop toll collection system. On highways, there will be one or more ETC lanes. The ETC charging method: through the dedicated short-range microwave communication between the vehicle-mounted RFID tag installed on the vehicle's windshield and the microwave antenna on the ETC lane at the toll station, using software networking technology to conduct background settlement processing with the bank, thereby achieving the purpose of vehicles passing through the toll station without stopping to pay the toll. Banks install this type of ETC express card with a post-payment system. ETC application conditions are as follows: Provide the original and photocopy of the vehicle owner's valid ID card and vehicle registration certificate; the photocopy of the driver's license must include the page with the most recent annual inspection seal; Postal credit card application form, which is used to bind the ETC card. After obtaining the credit card, swipe it twice and use the POS slip to collect and install the ETC vehicle-mounted device for free at the designated postal outlet, with no fees charged during the process; Be between 18 and 60 years old; Own a vehicle under personal name. Below are the precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large inclination angle of the windshield, which reduces the driver's field of vision. If ETC installation does not consider this, it will increase the driver's blind spot. Install it on the right side behind the rearview mirror to avoid obstructing the view. Do not affect charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement because it has a solar panel on the back for self-charging. Therefore, during installation, avoid the blackened areas on the windshield and do not install it where the solar panel might be blocked. Do not remove it randomly once installed: The button in the middle of the adhesive is an anti-removal lever, connected to a switch below. After installation, the windshield will press the anti-removal lever in. If removed randomly, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. When using ETC, note the following: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for ETC lane passage is 20 km/h. Driving too fast may prevent the vehicle device information from being read, resulting in failed toll deduction. When using a debit card bound to ETC, insufficient balance will also cause toll deduction failure.

What Causes the Car Temperature Gauge to Show Excessive Temperature?

Generally, if the water temperature gauge on the dashboard shows a high reading, it indicates a fault in the engine's cooling system. Here are some relevant details about the car cooling system: 1. Car Cooling System: The primary function of the cooling system is to dissipate heat into the air to prevent engine overheating. Another important role is to quickly warm up the engine and maintain it at a constant temperature. 2. Causes of Faults: Insufficient antifreeze in the engine cooling system may be due to leaks, such as water pump leakage, damaged pipes, or radiator damage. Alternatively, the cooling fan in the engine cooling system may not be functioning properly, leading to poor heat dissipation of the coolant. As a result, the water temperature warning light comes on, indicating excessive coolant temperature.
