How Many Kilometers is Considered the Break-in Period for a Car?

The break-in period for a car is typically between 1,000 to 3,000 kilometers. During this period, it is essential for the owner to control the speed appropriately, avoiding sudden braking and rapid acceleration. It is also recommended to warm up the engine before driving to ensure proper lubrication and prevent unnecessary malfunctions that could affect normal usage. Characteristics of a new car's break-in period: 1. More minor issues may arise. It is normal for a new car to experience minor faults during the break-in period, as the components have not yet fully adapted to each other. Poor driving habits can further increase the likelihood of faults, so owners should pay extra attention while driving. 2. Lubricating oil tends to degrade faster. The high friction between new components can raise the temperature of the lubricating oil during operation, and impurities may also mix into the oil, leading to oxidation and deterioration of the lubricant.

Is ETC Required?

ETC installation is necessary. According to the State Council's regulations, starting from 2020, vehicles without ETC will not enjoy toll discounts. In the future, only one manual lane will be retained at highway toll stations, and tolls can only be paid through manual lanes. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During free holiday periods, ETC users can still use highways, and no fees will be deducted when passing through ETC lanes. ETC Billing Principle: Highways will have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's windshield-mounted electronic tag and the microwave antenna in the ETC lane, and using computer networking technology for backend settlement with banks, vehicles can pay tolls without stopping at toll stations. All of this operates on the principle of "pass first, deduct later." Benefits of Installing ETC: Time-saving: Eliminates the hassle of waiting in queues. Green and eco-friendly: Reduces noise and exhaust emissions by eliminating stops at toll stations, lowering pollution. Reduces wear and tear: Saves costs by decreasing the frequency of vehicle starts and stops, reducing wear and fuel consumption. Improves efficiency: ETC lanes can theoretically increase traffic flow efficiency by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" explicitly states, "By 2020, key city clusters will achieve interoperability of transportation cards, and the proportion of vehicles using ETC will significantly increase." It also sets a target of "50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development plan. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will include promoting ETC for trucks and exploring deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments. This will provide comprehensive travel services for vehicle owners, meaning more application scenarios will support ETC usage.

What are the main functions of antifreeze?

Antifreeze serves several key purposes: 1. Cooling function: Cooling is the fundamental role of antifreeze. When the engine operates, it generates a significant amount of heat, with approximately 60% of this heat being dissipated into the surrounding space through the cooling system. 2. Heat dissipation: Antifreeze provides efficient heat dissipation, removing excess thermal energy from the engine to control the temperature of critical metal components. 3. Freeze protection: During winter when temperatures are low, antifreeze contains substances that lower the freezing point of water, allowing vehicles to continue operating in cold weather by preventing the cooling system from freezing. 4. Corrosion prevention: The cooling system consists of components such as radiators, water pumps, cylinder blocks, cylinder heads, and water distribution pipes made from various metals including steel, cast iron, brass, copper, and aluminum. Due to differing electrode potentials among these metals, electrochemical corrosion can occur in the presence of electrolytes. Additionally, acidic byproducts formed from the decomposition of glycol-based substances in the coolant, as well as acidic exhaust gases from fuel combustion that may infiltrate the cooling system, can accelerate corrosion within the system.

Where is the Quarter Mark on the Fuel Gauge?

Most vehicles will clearly mark the quarter position on the fuel gauge. The automotive fuel gauge is an indicator that displays the remaining fuel level in the vehicle, serving as a crucial reference for drivers to determine whether refueling is needed. By understanding the structure and markings of the fuel gauge, drivers can accurately assess the remaining fuel level or determine if the fuel gauge is functioning properly. Typically, fuel gauges feature two letters—E and F. E stands for empty (no fuel), while F indicates full. If the needle approaches E, it's time to refuel. Fuel gauges come in two types: analog (pointer-type) and digital. As the names suggest, analog gauges indicate fuel levels via pointer position, whereas digital gauges display remaining fuel through estimated remaining driving range. Generally, analog fuel gauges have marked graduations. Some vehicle gauges directly label positions like 1/4 or 1/2, where 1/4 clearly indicates the quarter-tank level. Other models may not show specific fractions but allow drivers to estimate the quarter position by equally dividing the gauge's graduations. Digital gauges also enable drivers to calculate remaining fuel based on the displayed range. When the gauge shows a quarter-tank remaining, it signals the need for timely refueling. Always monitor fuel levels during drives—running out of fuel mid-journey can be highly inconvenient.

Where is the best location to install an ETC tag?

The ETC installation position is generally in the upper middle part of the front windshield for most vehicles, while for large vehicles like trucks and buses, it is installed in the lower middle part. The suitable installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with anti-explosion film or those that have it installed later, it may affect the signal transmission of the microwave communication link, so it should be installed in the microwave sunroof strip. ETC stands for Electronic-Toll-Collection, meaning electronic toll collection system. To apply, the vehicle owner needs to provide their valid ID card and the original and photocopy of the vehicle registration certificate. If the application is done by a proxy, the proxy's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page stamped with the most recent annual inspection seal. A bank card for deducting highway tolls is also needed, and the vehicle must be registered under an individual's name aged between 18 and 60. Documents required for company vehicles: Introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle registration certificate; Vehicle to be equipped with ETC. Here are some precautions for ETC installation: Do not block the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, which reduces the driver's field of vision. If this is not considered during ETC installation, it may increase the driver's blind spots. Install it behind the rearview mirror on the right side to avoid blocking 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 that can charge itself. Therefore, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-removal lever connected to a switch. After installation, the windshield will press the anti-removal lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and making 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. Notes for using ETC: 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 toll payment for it. The ETC lane recognition speed is 20 kilometers per hour; driving too fast may result in failure to read the vehicle device information and cause toll deduction failure. When using a debit card linked to ETC, insufficient balance may also lead to toll deduction failure.
