Steps to use the air conditioning in a car: 1. Open the car doors and windows; 2. Use the fan for ventilation, wait two to three minutes for the hot air to dissipate before entering and starting the car; 3. Do not rush to close the windows, first turn on the external air circulation; 4. When the temperature inside and outside the car is similar, close the windows and switch to internal air circulation. After a car has been exposed to the sun in summer, do not immediately turn on the air conditioning upon entering. Instead, open all four doors first and allow natural ventilation for 5 minutes before turning on the air conditioning. Using the air conditioning during low-speed driving, especially when encountering traffic congestion, causes the engine to run at artificially higher speeds, which can reduce the lifespan of both the engine and the air conditioning compressor. Prolonged use of the air conditioning can lead to excessive pressure on the condenser, causing wear and tear on the cooling system.

As a seasoned driver with years of experience, I'm quite adept at using the car's air conditioning. After starting the engine, simply press the AUTO button on the center console, and it will automatically adjust the temperature and airflow to maintain a comfortable cabin environment. If you prefer manual control, turn the temperature knob to your desired setting—around 23°C in summer for optimal fuel efficiency, and wait until the engine warms up before using the heater in winter. Adjusting the fan speed is straightforward: press the fan icon button to increase or decrease airflow. Use higher fan speeds for quick cooling when it's stuffy, then lower it once the temperature stabilizes to save energy. Don’t forget the mode selection: press the defrost button to clear fogged-up windows for safer driving; toggle the recirculation switch as needed—use fresh air mode (external circulation) on highways and recirculation mode in traffic to avoid exhaust fumes. Regular maintenance is crucial: replace the cabin air filter annually to prevent odors, and in summer, open the windows to release heat before turning on the AC for better fuel economy. Safety first—avoid frequent AC adjustments while driving to stay focused.

How to Remove Glue After Peeling Off Car Film?

Methods to remove residual glue from car film: Use organic solvents or industrial alcohol; Use a hair dryer to soften the glue on the glass; Use cotton or cloth dipped in vinegar; Wipe gently with a cloth soaked in ethyl acetate. Methods to remove old car film from car glass: 1. Peel it off directly: Low-quality film is easier to handle, as its adhesive strength is not particularly strong, making removal relatively simple. High-quality car film is more difficult to remove and may require professional help or specialized tools. 2. Use vinegar: Apply vinegar evenly to the adhesive with a cotton swab. Through the glass, you can immediately see the vinegar slowly spreading between the glass and the adhesive. Then, scrape back and forth with the cotton swab, and soon the adhesive will start to peel off. There will be minimal residue left on the glass, which can be wiped clean with a paper towel, leaving the surface as good as new. 3. Use essential balm: Initially, there is no obvious reaction when essential balm comes into contact with the adhesive. Persistently apply the balm to the adhesive and then scrape with a cotton swab. Gradually, the adhesive will soften, and some parts will start to peel off. With continuous application and scraping, the reaction speeds up, and within about 2 minutes, the adhesive will be completely removed. 4. Use alcohol: Apply alcohol to the adhesive on the glass, and you will immediately see the adhesive slowly soften and dissolve. Gently peel it off by hand, and the adhesive will come off cleanly from the glass.

Why is the steering wheel of the new Santana particularly heavy?

The heavy steering wheel of the new Santana could be due to issues with the power steering system or power steering fluid, and it is recommended to promptly visit an auto repair shop for inspection and repair. Below is relevant information about the new Santana: 1. Reasons for a heavy steering wheel: If you notice that the steering wheel suddenly feels heavy while driving the new Santana, with obvious resistance when turning, and the steering wheel does not automatically return to the center after turning, you should be alert. This could indicate problems with the power steering system or power steering fluid. In such cases, do not dismiss it as a minor issue that can be ignored. It is crucial to repair it as soon as possible to prevent the fault from escalating and causing greater damage. 2. Low fluid levels: It is also necessary to check whether the power steering fluid is low or if there is any leakage. If the fluid is low, it should be replenished to the normal range. If the fluid level is adequate, check whether the power steering pump belt is too loose. If it is loose, tighten the belt. Additionally, check if the fluid is too dirty, which can reduce its flow efficiency. Generally, the fluid should be replaced every 2 years or 60,000 kilometers. Also, check the tire pressure, as a leak can cause the steering to feel heavier, requiring inflation.
