Audi A4L's horn sound setting when locking the car is configured through the vehicle's central control screen. Navigate to settings, find vehicle settings, and locate the lock sound option to make adjustments. The locking horn primarily produces sound through electromagnetic vibration. The electromagnetic coil attracts the moving contact switch of the relay to close, allowing current to flow to the horn terminal. This current activates the electromagnet inside the horn, causing the diaphragm to vibrate and produce sound. Taking the Audi A4L 2020 35TFSI Fashion Dynamic model as an example, this vehicle measures 4858mm in length, 1847mm in width, and 1439mm in height, with a wheelbase of 2908mm, and a top speed of 220 km/h.

Is a manual two-wheel drive an automatic transmission?

Manual two-wheel drive is not an automatic transmission; manual means manual transmission, and two-wheel drive is divided into front-wheel drive and rear-wheel drive. Here is some extended information: 1. Front-wheel drive: Because the chassis of front-wheel drive is lower than that of rear-wheel drive, it is faster on straight highways; however, when going uphill, the center of gravity shifts backward, reducing the adhesion of the front wheels and decreasing power. Additionally, the rear cargo in front-wheel drive vehicles should not be too heavy, otherwise, the performance will decline. 2. Rear-wheel drive: The chassis of rear-wheel drive is slightly higher than that of front-wheel drive; on straight roads, the acceleration is slightly slower than front-wheel drive, but the speed difference is minimal. When going uphill, the center of gravity shifts backward, and the rear-wheel drive shows its advantage as the adhesion of the rear wheels increases with the shift in the center of gravity, providing better power.
