Solutions for foggy windshield when using air conditioning in summer: 1. Avoid directing cold air towards the front windshield; 2. Dishwashing liquid or soap can be used for car window anti-fogging, as these detergents disrupt the attraction between water molecules, reducing surface tension; 3. There are specialized anti-fogging agents for car windows on the market that absorb moisture on the mirror surface, forming a water film to prevent fogging; 4. Slightly opening the windows can help balance the temperature; 5. If rainy days are frequent and opening windows is not suitable, you can turn on the external circulation for defogging. The correct air vent setting is to blow air towards both the front windshield and the foot area, or only towards the front windshield.

How to Save Fuel When Using Air Conditioning?

Here are methods to save fuel when using air conditioning: 1. Ventilate before turning on the AC: If the car has been parked in the sun during summer, the interior temperature rises sharply. Turning on the AC immediately after opening the door will take a long time to cool down and consume more fuel. The correct approach is to open the windows for ventilation first, then turn on the AC when the inside and outside temperatures are similar. 2. AC settings: If there's only the driver or one additional passenger in the car, generally the first AC setting is sufficient. Unless the weather is extremely hot, this can help save fuel. 3. Check the AC vents: Ensure the AC vents are clear of obstructions to allow proper airflow. Blocked vents can lead to prematurely increasing the AC setting, which also increases fuel consumption.

How to Control the Throttle to Maintain a Constant Speed?

When pressing the accelerator, ensure the force is gentle—press and release lightly. Below are relevant tips: 1. Avoid Sudden Acceleration: When starting or accelerating, do not stomp on the accelerator abruptly, as this only increases engine RPM, causing excessive noise and transmission wear while wasting fuel unnecessarily. Instead, press the accelerator gently, utilizing low-speed downshifting to increase torque for smoother acceleration. Gradually and evenly increase speed before accelerating further—this approach ensures a smoother drive in an automatic transmission vehicle. 2. Maintain Constant Speed: To achieve steady-speed driving via throttle control, first learn to modulate the pressure on the accelerator. Avoid pressing too deeply at once, and similarly, do not release the pedal too quickly after pressing it.
