What does front mean?

[RhettDella]

On a car's air conditioning system, "front" refers to the function of defogging the front windshield. It is usually represented by a fan-shaped symbol with several upward wavy arrows and the word "FRONT" at the bottom. Similarly, "REAR" indicates the button for defogging the rear windshield. Here are some additional details: 1. While driving, when there is a significant temperature difference between the inside and outside of the car, fog may form on the windshield, which can severely obstruct the driver's view. In such cases, you can press either the "FRONT" or "REAR" button, depending on whether the fog is on the front or rear windshield, to remove the fog. 2. When driving, it's also important to pay attention to the use of the internal and external air circulation systems. If you're driving for an extended period, it's advisable not to keep the internal circulation on continuously, as this prevents fresh air from entering the car, which is not good for the occupants.
