Which air circulation mode to use when the car interior temperature is high?

On highways, it is recommended to use the external air circulation mode. Due to wind resistance and high speeds, opening windows is not advisable on highways. Prolonged use of internal air circulation can lead to oxygen deprivation in the brain, impairing reaction time and judgment, which is extremely dangerous. Additionally, the air quality on highways is generally good with low exhaust concentrations, making external circulation a suitable choice. Precautions for highway driving are as follows: 1. Safety inspection: Check for potential safety hazards before driving. Conduct a thorough vehicle inspection before entering the highway. 2. Seat belts: Always wear seat belts in both front and rear seats, and avoid placing loose objects in the car. 3. Maintain lane discipline: Avoid frequent lane changes on highways, switching between passing lanes and travel lanes. Never make sudden unannounced decelerations or stops in travel lanes. Do not drive side by side with other vehicles, remain in the passing lane for extended periods, or attempt to overtake from the emergency lane. Also, prepare for lane changes well in advance when exiting the highway to avoid missing your exit.

Why is there frost on the inside of car windows?

Frost forms on the inside of car windows because: after parking, the humidity inside the car is relatively high. As the car's temperature drops, the moisture in the air inside the car condenses on the windows when it encounters the cold. When the temperature drops to a certain level, the water droplets adhering to the windows freeze into ice. Car windows are an important part of the vehicle body, designed to meet the needs of interior lighting, ventilation, and the visibility of the driver and passengers. Methods to remove frost from the inside of car windows include: 1. Using a hard plastic scraper to chip away the ice; 2. Spraying a de-icing agent onto the windows; 3. Covering the windows with a cloth after parking; 4. Turning on the vehicle's warm air to blow on the windows once the engine's coolant temperature rises; 5. Opening the doors to ventilate after parking to equalize the interior and exterior temperatures.
