Can the ETC card be removed at will?

The ETC card can be removed, but the ETC device will not function without it. According to the "Rules for the Use of the Non-Stop Rapid Transit System," the ETC card must be inserted into the OBU device to operate normally; 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, a prompt sound will indicate that the device is activated. Without the card, the device remains in a dormant state and cannot recognize vehicle information at toll stations, so removing the card disables ETC functionality. ETC is an electronic toll collection system, also known as an automatic road toll system. It is specifically designed for toll roads, commonly found on highways, toll bridges or tunnels, and certain urban road sections to alleviate traffic congestion. ETC Deduction Principle: Highways 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, the system connects with banking networks for backend settlement, allowing vehicles to pass toll stations without stopping. This operates on a "pass first, deduct later" principle. 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 booths; Reduced wear and tear: Saves costs by minimizing frequent starts and stops, lowering vehicle wear and fuel consumption; Improved efficiency: ETC lanes can theoretically increase traffic flow by 2-3 times, making traditional ETC faster and more high-tech. Compared to license plate payment, ETC is more mature and advantageous. More policy support: The State Council's "13th Five-Year Plan for the Development of a Modern Integrated Transportation System" explicitly states the goal of "achieving interoperability of transportation smart cards in key urban 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." Future possibilities: Beyond improving ETC installation convenience and passenger vehicle usage rates, future efforts will promote ETC adoption for trucks and explore deeper integration of ETC systems with vehicle-to-vehicle communication, vehicle-to-infrastructure coordination, and other smart transportation developments, providing comprehensive travel services for car owners. This means more application scenarios will support ETC usage.

Does Using the Car Air Conditioner's Heating Function Consume More Fuel?

Using the car air conditioner's heating function does not significantly increase fuel consumption. When the air conditioner is cooling, the compressor needs to be activated, which consumes fuel. However, heating is achieved by utilizing the heat generated by the engine. Apart from the minimal fuel required to power the fan that circulates the warm air, no additional fuel-consuming devices are engaged, so it does not lead to extra fuel consumption. Below is an introduction to car air conditioning: 1. The air conditioner's compressor has a high power demand, requiring direct energy supply from the generator, which is driven by the engine, thus adding to fuel consumption. 2. During winter, it is recommended to keep the windows closed and only use the fan to transfer heat from the engine compartment into the cabin, as using the air conditioner would be wasteful. There is no need to press the air conditioner button in winter; simply turning on the heating is sufficient, as the heat comes from the engine and does not consume extra fuel. Use the air conditioner's heating function when the car interior is too cold in winter, and the cooling function when it's too hot in summer. 3. For automatic air conditioning, pressing the AUTO button once will activate the system and set it to a reasonable temperature, typically 25 degrees Celsius, which is calculated by the computer based on the temperature difference inside and outside the car. The temperature can also be adjusted manually using the temperature control knob. When the air conditioner is on, the AC button's light will be illuminated. To turn off the air conditioner, press the AC button until the light goes off.

When Should You Change Your Car's Engine Oil?

There are several methods to determine when to change your car's engine oil: 1. Observe with an oil test paper: Take a small amount of oil from the dipstick and drip it onto the oil test paper, then let it sit overnight, waiting for the oil to fully spread on the paper. The sharper the edges between the oil ring, sediment ring, and diffusion ring, the more the oil performance has degraded. 2. Judge based on driving feel after an oil change: Engine oil has a 'shelf life.' If you feel the power is 'sluggish' or acceleration is slower during a certain period, it's time to change the oil. 3. Smell test: Pull out the dipstick and smell it closely. If there is a strong sour odor, the oil has deteriorated and should be changed. 4. Hand rubbing method: Rub the old oil between your thumb and index finger repeatedly. Good-quality oil will feel lubricated, with few grindings and no friction. If you feel impurities, poor viscosity, or even a rough sensation, it's time to change the oil. 5. Color identification method: Take a clean white filter paper and drip a few drops of old oil on it. After the oil seeps through, good-quality oil will have no powder, feel dry and smooth to the touch, and have a clear yellow infiltration zone. If it appears dark brown with impurities, it should be changed. 6. Light inspection method: Pull out the dipstick and hold it at a 45-degree angle under light to observe the oil droplets. If you can clearly see no grinding particles in the droplets, the oil is good. If there are many grinding particles, it's time to change the oil.

What brand of tires does Chery use?

Chery's original tires are from the Giti brand. Chery A3 matching tires: 205/55R16, but there is more than one matching tire, including GitiComfort228, Goodyear Eagle NCT5, and Maxxis MA-530. Tires are one of the most important components of a car, with the following main functions: Supporting the vehicle's weight, bearing the car's load, and transmitting forces and moments in other directions; transmitting traction and braking torque to ensure good adhesion between the wheels and the road surface, thereby improving the car's power, braking, and passability; working together with the car's suspension to cushion impacts during driving and dampen the resulting vibrations.

Why does the car overheat when the AC is on?

The main reasons for engine temperature rise when using AC are as follows: 1. Cooling fan malfunction: Normally the electric cooling fan has two speeds - low speed and high speed. The high speed engages when AC system pressure is too high or when engine coolant reaches 103°C. 2. Insufficient thermostat opening: When the thermostat opening is too small at normal temperatures, it slows down engine coolant circulation, causing overheating at low speeds. 3. Water pump cavitation: If the water pump shaft cracks, it may cause cavitation when coolant temperature rises, leading to overheating. 4. Wiring issues: Poor grounding of the battery's negative cable or engine coolant temperature sensor may cause false high temperature readings on the gauge (known as false overheating).

How Many Kilometers Are Required for Subject 2?

There is no mileage requirement for Subject 2 learning. According to relevant regulations, you can schedule the exam as long as you complete the required training hours. Based on the basic hour requirements, additional hours are allowed but cannot be reduced. Each student's classroom and practical training time must not exceed 4 hours per day. Below is an introduction to the content related to the Subject 2 exam: 1. Assessment content: The five assessment items are reversing into a garage, parallel parking, stopping and starting on a slope, turning at a right angle, and driving on a curve. 2. Requirements: Subject 2 requires 26 training hours, including 2 hours of theoretical knowledge, so the actual practical training is 24 hours.
