How to Retrieve a Lost Car Key?

There are several methods to deal with a lost car remote key, which include: 1. Use the spare key. 2. Visit a 4S shop or auto parts market to have a new key made. When getting a new key, remember to bring your driver's license, vehicle license, and even the motor vehicle registration certificate. Daily precautions for car key usage: 1. Every time you exit the car, even if it's just for a few minutes, turn off the engine, remove the key, and lock the car to prevent theft. 2. Keep the car key away from water, avoid strong vibrations, and stay clear of magnetic interference. If the key is damaged, it needs to be replaced. 3. Keep the spare key separate from the main key, and never lock the spare key inside the car, especially for vehicles with one-button start or engine immobilizer systems, as the spare key can fully start the engine. 4. If you can't replace the lost key immediately, avoid leaving valuables in the car. Additionally, consult your insurance company about the details of theft-related compensation to ensure you have the necessary evidence in case of vehicle theft.

Do I need to remove the card when the in-vehicle ETC is not in use?

It can be unplugged, but the ETC device will not work without the card. According to the "Rules for the Use of Non-Stop Fast Pass Systems," the ETC card must be inserted into the OBU device to function properly; otherwise, user information cannot be read. If the card is removed, you can use the manual lane and have the staff swipe the card. When the ETC card is inserted into the OBU device, there will be a prompt sound, indicating that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations, so you need to reinsert the card when you need to use it. ETC is the Electronic Toll Collection system, also known as the Automatic Road Toll System. It is a road toll method specifically designed for toll roads, commonly found on highways, bridges or tunnels with toll policies, and some sections of urban centers to alleviate traffic congestion. ETC Deduction Principles: There will be one or more ETC lanes on highways. Through microwave-specific short-range communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane at the toll station, the system uses computer networking technology to settle accounts with the bank, achieving the goal of vehicles not needing to stop at toll stations to pay road and bridge fees. All of this is based on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and eco-friendly: Low-carbon, vehicles pass toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Reduced wear and tear: Saves costs, reduces the frequency of vehicle starts and brakes, and lowers wear and fuel consumption; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times or more, making traditional ETC updates faster and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation cards in key urban clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also set a clear target in the "13th Five-Year" comprehensive transportation development indicators: "By 2020, the ETC usage rate for road passenger vehicles will reach 50%." More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, the future will also promote the use of ETC for trucks and explore the deep integration of the ETC system with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation development directions, providing car owners with comprehensive travel services. This means more application scenarios will support ETC applications.

What is the function of the coolant reservoir?

The engine cooling system is equipped with a coolant reservoir, the main purpose of which is to visually check if the coolant is insufficient and to store coolant. The coolant in the car's cooling system is a type of long-lasting antifreeze and anti-rust coolant. It not only prevents water from freezing but also reduces scale formation, wear on the water pump impeller, and enhances heat dissipation capacity. Below is a detailed introduction: 1. When the coolant temperature rises and its volume expands, the liquid pressure will push open the valve on the radiator, allowing the coolant or steam from the radiator to enter the reservoir through the steam connecting pipe. When the coolant temperature decreases, the pressure inside the radiator drops, and the coolant flows back to the radiator through the intake valve on the radiator cap via the connecting pipe. Additionally, the reservoir has a steam vent pipe at the top cover. If the steam pressure becomes too high, the steam can be released through this vent pipe. When the coolant level in the reservoir drops to the lower mark, it should be replenished promptly up to the upper mark. 2. The coolant level should be checked when the engine is cold. The level should always be between the minimum (MIN) and maximum (MAX) marks on the reservoir. The antifreeze content in the coolant should ensure it remains liquid at low temperatures, and the coolant should also possess anti-corrosion properties and high-temperature stability. To maintain the coolant's performance, it should be replaced every two years, preferably at the beginning of the severe cold season. When replacing the coolant while the engine is hot, wait for 15 minutes after shutdown or until the temperature drops below 100°C. Protect your hands with a cloth and slowly loosen the radiator cap to avoid burns. If more than 1L of coolant needs to be replenished, it indicates significant coolant loss, and the vehicle's cooling circulation system should be inspected.

Is it serious if there's a burnt smell after revving the throttle uphill?

Is it serious if there's a burnt smell after revving the throttle uphill? The burnt smell is most likely due to a clutch issue, as slipping clutch plates often emit this odor. When climbing a slope, the clutch needs to be fully engaged to ensure proper power transfer for smoother uphill driving. Related information about gasoline additives is as follows: Introduction: Gasoline additives are liquids that help ensure complete combustion of car fuel, typically added directly to the fuel tank along with gasoline. Function: Using gasoline additives cleans the fuel system, and regular use helps control carbon buildup, keeping the engine in optimal condition.

At what moisture content does brake fluid need to be replaced?

Brake fluid needs to be replaced when its moisture content reaches 3%. It is an important fluid in the braking system and requires regular replacement. If the moisture content in the brake fluid is too high, it can lead to reduced braking force and extended braking distance, which affects the vehicle's driving stability and safety. After replacing the brake fluid, it is essential to bleed the air from the brake system lines; otherwise, it can also affect braking force and distance. Brake fluid, also known as hydraulic brake fluid, is the liquid medium used in hydraulic braking systems to transmit braking pressure, making it an indispensable part of the braking system. Based on type, brake fluid can be categorized into castor oil alcohol-based, synthetic, and mineral oil-based varieties.

Can the Shanghai green license plate be reused when changing cars?

Shanghai green license plates can be transferred to a new car under certain conditions. The requirements are that the new energy vehicle must be registered in the city and use a dedicated license plate quota. The dedicated license plate quota cannot be transferred or changed within 3 years from the date of activation. Below are specific details about new energy vehicles: Definition: New energy vehicles refer to vehicles that use unconventional vehicle fuels as power sources, integrating advanced technologies in power control and driving systems to form vehicles with advanced technical principles, new technologies, and new structures. Types: New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, hydrogen engine vehicles, etc.
