The ECON on a car air conditioner is actually an energy-saving mode of the air conditioner, which only takes effect when the air conditioner's cooling function is activated. The air conditioner compressor is driven by the engine and can consume up to 20% of the engine's power. After activating the ECON mode, the vehicle will reduce the power consumption of the air conditioner while ensuring its cooling effect, thereby achieving fuel savings. The method to activate the air conditioner's economy mode is very simple. The owner only needs to press the "ECON" button after turning on the air conditioner. When the light on the button is on, the air conditioner's cooling system is turned off, and only natural air or warm air is provided. The introduction to the car air conditioner's ECON mode is as follows: Usually, the car air conditioner has the "A/C" symbol to indicate whether the air conditioner is on or off, while ECON only takes effect when the air conditioner's cooling function is activated, representing the air conditioner's economy mode. In this state, the compressor will also work. Compared to the normal mode, the control point of the compressor is increased, and the compressor does not continuously engage during operation. The start and stop points of the compressor are controlled by the evaporation temperature. In normal mode, the compressor's start and stop points are 2~4°C. In ECON mode, the compressor's start and stop points are 8~10°C. The lower the temperature, the longer and harder the compressor will work. Activating the ECON mode will save the engine's power output and save fuel. The functions of the car air conditioner: Achieve cooling effects by continuously changing the state of the refrigerant in a cycle; Remove dust, odors, smoke, and toxic gases from the air inside the car, making the air fresher, and humidify the air inside the car to increase its relative humidity; Use the engine coolant, waste heat, or heat generated by a burner as a heat source for heating, and heat it through a heater, then blow the heated air into the car or outside air to raise the temperature at the air outlet for heating purposes; Draw in fresh air from outside for ventilation and air exchange, which also helps prevent window fogging. Precautions for using the air conditioner in the car: Do not set the air conditioner temperature too low. A large temperature difference between the inside and outside of the car can easily cause the driver to catch a cold, and excessively low temperatures may also pose a risk of arthritis to the occupants. Control the direction of the air outlet. Based on the principle that cold air sinks and hot air rises, when controlling the air conditioner's air outlet, you can follow the rule of pointing the air outlet upward when cooling and downward when heating. Do not turn on the air conditioner immediately after the car has been exposed to the sun. After the car has been exposed to the sun, the temperature inside will be very high. First, open the windows for ventilation, and then turn on the air conditioner after the hot air has been expelled.

After driving for so many years, I'm very familiar with the ECON button. It's actually the air conditioning's economy mode—pressing it reduces the compressor's workload to save fuel. Regular AC immediately adds over a dozen horsepower load to the engine, but ECON mode is smarter—it makes the compressor work intermittently, like pausing when the target temperature is reached. Especially in traffic jams, this feature saves me three to four hundred bucks in fuel annually. However, avoid using it during extreme summer heat of 40°C, as cooling becomes much slower. I usually turn off ECON first, blast the AC for ten minutes to cool down quickly, then reactivate it.

What is the simplest and most accurate method for A2 reverse parking?

Drive the car forward until it is roughly aligned with the car in front, then adjust the right-side mirror until the right wheel is visible. Keep the steering wheel fully turned to the right and reverse slowly until the left-side mirror shows the front of the car behind; use the right-side mirror to straighten the car body. When the right-side mirror is almost parallel with the taillight of the adjacent car, straighten the steering wheel and continue reversing. Once the car is inside the parking space, press the clutch firmly, check if the rear of the car is properly positioned, then press the clutch and brake, and shift to neutral.

How to Choose Between A6 and Q5?

Audi A6's front fascia is more impactful, with this generation emphasizing a sportier style, blending elements of sportiness and elegance into its composed appearance. Audi Q5's angular front-end design adopts the Q7's design language, incorporating chrome accents for a more robust and streamlined look. Audi A6's full LCD instrument cluster and large central display screen exude a sense of technological sophistication and luxurious fashion. Audi A6 is equipped with high and low power versions of a 2.0T engine, delivering stable performance on highways and during turns, paired with a 7-speed dual-clutch transmission. Since Audi Q5 replaced its 8AT with a 7-speed dual-clutch transmission, like many vehicles today, it still offers a remarkably smooth driving experience.

How to Fix the AFS OFF Light?

AFS OFF light indicates that the headlight's adaptive front-lighting system (AFS) is turned off. Re-enable the AFS function. Check the AFS module, use a diagnostic scanner to match settings and clear fault codes to resolve the AFS warning light. AFS stands for Adaptive Front-lighting System. If the indicator light stays on, it means this function is currently disabled. Ensure the vehicle's power is off, then open the hood and locate the negative terminal of the battery.

What is the procedure for handling a full 12-point deduction on a driver's license?

The procedure for handling a full 12-point deduction on a driver's license is to participate in a 7-day traffic safety laws, regulations, and related knowledge training within 15 days, followed by a relevant examination. Upon passing the exam, the points will be cleared, and the driver's license will be returned. Process for handling vehicle violation point deductions: Bring your ID card, driver's license, and vehicle registration certificate to the violation processing office. Take the penalty decision notice to the designated bank to pay the fine (once the penalty decision notice is printed, the fine must be paid within 15 days. After 15 days, a 3% late fee will be charged daily, with the total late fee not exceeding the total fine amount). After paying the fine and obtaining the receipt, keep the receipt properly. Check the violation information online a few days later. If the violation information disappears, the receipt can be discarded. However, if the violation information remains online, take the payment receipt to the legal department of the traffic police team to explain the situation. After confirmation by the staff, the violation information will be directly deleted.

What Causes the Rear of the Car to Cross the Line During Parallel Parking?

The reason the rear of the car crosses the line during parallel parking is either starting to park too early or being too far from the line. You can drive forward a little more before stopping to ensure the car body is slightly closer to the parking space line. When parking, try to stay slightly to the right, which makes it easier to reverse into the parking space, while also paying attention to the distance between the front and rear. More details are as follows: 1. Definition of Parallel Parking: Parallel parking is part of the second subject in the driver's license test. It is increasingly common in urban areas, especially as parking spaces in formal lots become more limited. Many places now designate parking spaces along the sides of streets, creating "parallel parking spaces." 2. Changes: In the past, parallel parking used four poles placed on the ground to symbolize the four corners of the parking space. One criterion for successful parking was whether the vehicle entered the space without touching these poles. After the new traffic regulations were implemented, parallel parking no longer uses poles; instead, ground markings define the boundaries of the parking space. For students learning to drive with a C1 license, the length of the parallel parking space is 1.5 times the vehicle's length plus 1 meter. The vehicle must be driven parallel to the parking space, then reversed into the space in one continuous motion without stopping. As long as the car is parked within the boundaries without crossing the lines, it is considered a pass.

What Causes Low-Speed Jerking?

Transmission jerking is the impact sensation caused by the inertia of moving parts inside the engine. Below are the reasons for engine jerking: 1. Causes of engine jerking: During the process where the engine speed is either increased or decreased, if not handled properly, sudden changes in engine speed during gear shifts can cause the inertia of the engine's moving parts to react against the vehicle body. 2. Low-speed jerking: Many drivers experience this issue. When driving at low speeds, the gear frequently shifts between first and second, and the clutch repeatedly engages and disengages. If power transmission cannot be smoothly completed within a short time, common low-speed jerking occurs. Jerking sensations are normal during startup and low-speed driving, usually due to turbocharger engagement at low RPMs, which affects engine speed. 3. Upshift jerking: This is mostly caused by the transmission's response speed being insufficiently fast. The upshift speed cannot keep up with the throttle input, so the jerking sensation occurs at the moment of gear shift. 4. Downshift jerking: This is mostly due to the intervention of the energy recovery system. Once the driver releases the throttle pedal or presses the brake pedal, the generator immediately starts working, placing additional load on the engine. This affects the engine speed, causing it to be out of sync with the clutch plate speed, resulting in a jerking sensation.
