The ETC machine installed in the car is called an OBU device. Once installed, activated, and a card is inserted, it can be used normally. ETC is an electronic toll collection system, also known as an automatic road toll system. It is a road toll method specifically designed for toll roads, commonly seen on highways, bridges or tunnels with toll policies, and certain sections of urban centers to alleviate traffic congestion. 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 channels. Additionally, newly installed ETC devices cannot be used on highways immediately; they must be activated first. During free holiday periods, vehicles with ETC can still use highways, and no fees will be deducted when passing through ETC lanes. ETC Deduction Principles: Highways have one or more ETC lanes. Through dedicated short-range microwave communication between the vehicle's electronic tag installed on the windshield and the microwave antenna in the ETC lane, and by using computer networking technology for backend settlement with banks, the system achieves the purpose of collecting tolls without requiring vehicles to stop at toll stations. All this is based 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 allowing vehicles to pass toll stations without stopping, thus minimizing pollution. Cost-saving: Reduces wear and tear and fuel consumption by minimizing frequent starts and stops. Users also enjoy a 5% discount on toll fees. Improved efficiency: ETC lanes can theoretically increase vehicle throughput by 2-3 times, making traditional ETC systems more advanced, faster, and higher-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 the goal of "achieving interoperability of transportation cards in key city clusters by 2020 and significantly increasing the proportion of vehicles equipped with ETC." 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. Future possibilities: In addition to continuously improving the convenience of ETC installation and usage rates for passenger vehicles, future efforts will include promoting ETC use 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. ETC Usage Notes: The ETC transaction sensing range is 8 meters. If the vehicle in front stops, maintain a distance of at least 10 meters to prevent automatic fee deduction for the wrong vehicle due to ETC device failure or absence. The ETC lane recognition speed is 20 km/h. Driving too fast may result in failure to read the vehicle's device information, leading to toll deduction failure. Unauthorized removal or movement of the OBU device, or detachment/loosening of the ETC electronic tag, will render the tag invalid. It can be taken to the bank where the ETC card was issued or a highway service center for inspection. If the detachment is not due to human error, reactivation is sufficient. When using a debit card linked to ETC, insufficient balance may cause toll deduction failure. Follow the guidance of on-site staff to use the manual MTC lane and pay with cash or card. Thick car windshields may cause poor signal reception. This is especially important for vehicles that have had their windshields replaced after accidents or for those with modified front windshields.

What Does a First-Hand Car Mean?

A first-hand car refers to a vehicle with zero transfer records, meaning it is being sold for the first time after initial registration. It is a subcategory within the used car market and is also referred to as a 'used car'. Purchasing a first-hand car not only saves on purchase tax but also significantly reduces the vehicle price, provided you acquire a well-maintained first-hand car. Differences Between First-Hand Cars and Used Cars: Different Definitions: A first-hand car primarily refers to vehicles purchased directly from dealers with first-time transfer records, whereas used cars are those transferred from previous owners, typically with two or more transfer records. Different Purchase Channels: First-hand cars are commonly found at 4S stores, auto malls, online platforms, or regional brand agents. Used cars can be purchased at used car markets, online used car platforms, from individual owners, or at vehicle auction exchanges. Price Differences: First-hand car prices are generally stable with minimal fluctuations, while used cars are known for their higher cost-performance ratio. Condition Differences: First-hand cars come with brand-new configurations, whereas used cars require thorough inspection of their current and historical conditions.

What are the gears of a Volkswagen manual transmission car?

The middle position is neutral, where the vehicle's power is not transmitted through the transmission. The R gear is the gear selected when reversing. The remaining gears range from 1st gear to 5th or 6th gear or even higher, depending on the number of gear configurations in the transmission. The specific details are as follows: 1. First gear: Starting gear, the gear used to start the car. It has a similar gear ratio and performance to the reverse gear, so it is not suitable for continuous high-speed operation. Generally, you can shift to second gear once the car starts moving and gains momentum. 2. Second gear: Passing gear, mainly used for navigating complex road conditions and handling complicated situations, such as sharp-angle (right-angle) turns without special obstacles, densely populated and bustling areas, steep slopes, and bumpy roads. 3. Third gear: Transition gear, mainly used for low-speed driving in urban areas. Depending on the situation, you can easily accelerate to shift to fourth gear or decelerate to shift back to second gear. 4. Fourth gear: Driving gear, mainly used for prolonged high-speed and economical driving. Most vehicles achieve their most economical speed in the low-speed range of fourth gear. 5. Fifth gear: High-speed gear, mainly used for long-distance highway driving.

What is the fuel tank capacity of the 2021 Corolla?

The 2021 Corolla has a total of 12 models. Among them, the 1.8L models have a fuel tank capacity of 43 liters, while the 1.2T and 1.5L models both have a fuel tank capacity of 50 liters. This data is officially released. The 2021 Corolla uses 92-octane fuel. The 1.8L models have a fuel consumption of 4-4.1L per 100 kilometers, allowing a driving range of 1048-1075km on a full tank. The 1.2T and 1.5L models have a fuel consumption of 5.2-5.6L per 100 kilometers, with a driving range of 892-961km on a full tank. During daily driving, it is essential to monitor the remaining fuel level in the tank. This is usually done by observing the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is recommended to refuel when only 2 segments remain to avoid running out of fuel mid-journey. In actual refueling situations, the amount of fuel may exceed the marked capacity. This is because the manufacturer's specified fuel tank capacity is measured from the bottom of the tank to the safety limit. There is additional space from the safety limit to the tank opening, which is reserved to allow for fuel expansion due to temperature increases without causing overflow. If fuel is filled up to the tank opening during refueling, the actual amount of fuel added may exceed the marked capacity.
