What is the button on the side of the driver's door of an Audi A4?
2 Answers
The button on the side of the driver's door is the interior air circulation alarm switch. Below is some relevant information about the Audi A4: 1. Introduction: As the first model to introduce the long wheelbase and turbo concept, from the B5 to the B8, the A4L has enjoyed enduring popularity. The new A4 has abandoned the teardrop design, added quattro all-wheel drive mode, and features a more stylish and sporty exterior, with outstanding power and handling. The interior is exquisitely crafted, rich in technological features, and spacious, making it highly practical among B-segment models. 2. Achievements: The Audi A4, produced by FAW-Volkswagen, is the first B-segment sedan from an international luxury brand in China, filling the gap in the domestic B-segment sedan market and reinforcing FAW-Volkswagen's leading position in the domestic luxury car market. This was quite significant at the time, and judging by the sales of the Audi A4 in China, it has indeed been a success.
As soon as I started driving the Audi A4, I noticed the row of buttons on the door panel is quite practical, mainly for controlling the window operation. The largest button on the left is for the driver's window, the one slightly to the right is for the front passenger window, and there are two more buttons further right for the rear windows. In the middle, there's a small rotary knob for adjusting the side mirrors—turning it moves the mirrors up, down, left, or right, and pressing it down activates the heating function to defog them on rainy days. At the very bottom, there's a lock button that secures all doors with a light press, which is very convenient. These buttons are designed with great ergonomics, offering a solid tactile feel, allowing for easy operation without distraction while driving. During my daily commute, which often involves traffic jams, I frequently use them to open the windows for fresh air or close them for noise insulation. Audi has done a great job here—the attention to detail makes things much easier.
