The method to turn off the automatic start-stop function in the 14th Generation Sylphy is as follows: 1. Press the start-stop button directly, and the dashboard will indicate that the system is turned off. 2. If you want to use this function again, press the button to turn it back on. It is recommended to turn off the automatic start-stop function under the following circumstances: 1. When driving on steep slopes, it is advisable not to activate the automatic start-stop. 2. It is best to turn off the start-stop system when driving through water. 3. In cases of severe traffic congestion, it is also recommended to turn off the automatic start-stop. This is because the engine stops for a longer period during heavy traffic, causing the combustion chamber temperature to drop. Incomplete combustion of hydrocarbons and paraffin can form carbon deposits on the cylinder walls. Carbon deposits can increase fuel consumption and reduce engine power. Ironically, the automatic start-stop function, designed to reduce fuel consumption, may end up increasing it.

Turning off the auto start-stop function on the Sylphy is actually quite simple. I always press that button before driving. On the 14th-generation Sylphy, the button is usually located on the left side of the steering wheel or the center console, labeled "ECONOMY" or "A/off". Pressing it to illuminate the light indicates the auto start-stop is deactivated. Just operate it once immediately after starting the engine, but it will automatically reactivate the next time you start the car, so you need to get used to the operation. Why turn it off? During peak traffic jams, frequent auto start-stop cycling can cause vehicle shuddering, reduced air conditioning cooling efficiency, and may accelerate battery aging. After driving for two years, I've found that keeping it off results in smoother city driving with negligible fuel consumption difference. Regularly checking for system updates is also important to prevent button malfunctions requiring reset.

Does Using Air Conditioning in the Car Consume More Fuel?

Using air conditioning consumes approximately 20% of the engine's power, and indeed, running the AC in a car leads to higher fuel consumption. When the air conditioning cooling system is activated, the electromagnetic clutch engages, the compressor operates, and the engine needs to burn more fuel to provide sufficient energy to drive this load. Below are the reasons why using air conditioning in the car increases fuel consumption: 1. Prolonged use of air conditioning: It's okay to use the AC, but avoid running it for extended periods continuously. Prolonged use can easily wear out the engine, thereby increasing fuel consumption. Moreover, keeping the AC on for long durations in the small, enclosed space of a car is not conducive to breathing fresh air and can be harmful to health. 2. Blocked air vents: Car owners should ensure that the air conditioning vents are not obstructed by debris, allowing unimpeded airflow. If the vents are blocked, the intensity of the cool air is affected, prompting the driver to lower the AC temperature further, which not only increases fuel consumption but may also shorten the AC's lifespan. 3. Turning on the AC immediately after starting the car: When starting the vehicle, avoid turning on the AC right away, as the engine hasn't fully warmed up yet. Activating the AC at this point increases the engine's load. It's better to wait until the car has fully started and been driven for a while before turning on the AC, which prevents overburdening the engine and reduces fuel consumption.

What is the difference between Su E and Su U license plates?

The difference between Su E and Su U license plates is: although both types of license plates belong to Suzhou, Su U plates are supplementary plates introduced because Su E plates were insufficient. The reason for the shortage of Su E plates is that many vehicles in the Shanghai area found it difficult to obtain Shanghai plates, so Su E plates were widely used in the early stages. Relevant information about license plates is as follows: 1. License plates, commonly known as car plates, are plates hung on the front and rear of vehicles, usually made of aluminum, iron, plastic, or paper, engraved with the vehicle's registration number, registration area, or other relevant information. 2. License plates serve as the numbering and information registration for vehicles. Their main function is to identify the vehicle's registered area through the plate and to trace the vehicle's owner and registration details based on the plate.

How to Turn on the Air Conditioning in a Buick Business Vehicle?

To turn on the air conditioning in a Buick business vehicle, follow these steps: 1. For older Buick business models with manual air conditioning, adjust the control knobs located in the central console area. The red zone controls the warm air temperature, while the blue zone controls the cold air temperature. 2. Newer Buick business models feature automatic air conditioning—simply set the desired temperature. Additional tips: It's important to time the use of the air conditioning correctly. Upon entering the vehicle, first open the windows for ventilation and activate the external circulation to expel hot air. Once the cabin temperature has decreased, switch to internal circulation. This approach avoids placing additional strain on the idling engine, saving fuel and protecting the engine. Before reaching your destination, turn off the air conditioning in advance and switch to external circulation to utilize natural airflow and residual cooling, maintaining a comfortable cabin temperature.

What to Prepare for Long-Distance Travel?

Things to bring for a long-distance trip include: 1. Documents: When driving long distances, it's essential to carry necessary documents such as the vehicle registration certificate, driver's license, and ID card. These three documents are indispensable while driving. Additionally, having insurance certificates and the vehicle's certificate of conformity can help avoid troubles during the journey. 2. Electric air pump: During long-distance driving, you might encounter situations with insufficient tire pressure. If you can't find a place to inflate your tires, an electric air pump can be used to inflate them. 3. Jumper cables: It's advisable to carry jumper cables for long trips. If you accidentally leave the car headlights on and drain the battery, making the car unable to start, you can use jumper cables to borrow power from passing vehicles. 4. Warm clothing: In winter, temperatures can be quite low, and without using the car's heater, it can get cold inside the vehicle, so warm clothing is necessary. 5. Spare tire: A spare tire is usually kept in the car. Before a long trip, check the spare tire's condition. In case of a tire blowout on the highway, the spare tire can be used as an emergency replacement. 6. Snow chains: Winter long-distance travel might involve snowy conditions, making snow chains an important tool. When installing snow chains, ensure they are not too loose to prevent unnecessary wear on the tires.

What are the techniques for removing tires with sensors?

Keep the bird head 10 cm away from the valve (the valve is located below the bird head), use a pry bar to lift the tire, select reverse rotation, and peel the tire bead past the valve. Then switch to forward rotation. During installation, position the valve at the 4~5 o'clock direction and use the auxiliary arm to prevent tire slippage.
