What are the functions of the P button in Mercedes-Benz cars?

In the Mercedes-Benz C200L, the P button on the center console has the following function: it activates the radar when driving on narrow roads, helping to avoid unnecessary scratches and improving driving safety to a certain extent. Definition of Automotive Radar: Automotive radar, as the name suggests, is radar used for cars or other ground motor vehicles. Therefore, it includes radars based on various technologies such as laser, ultrasonic, and microwave, with different functions like obstacle detection, collision prediction, adaptive cruise control, and employing different working principles. Functions of Automotive Radar: The parking radar is a safety auxiliary device when parking or reversing a car. It can inform the driver about surrounding obstacles through sound or more intuitive displays, eliminating the troubles caused by the driver's need to look around when parking, reversing, or starting the vehicle, and helping the driver overcome blind spots and unclear vision.
After driving a Mercedes for several years, I've found that the P button is specifically for parking—it locks the transmission to prevent the car from moving. In city driving, whether stopping at a red light or parking while shopping, this button is particularly crucial. For instance, last week when parking on a steep slope, I engaged the handbrake and then pressed the P button, keeping the car firmly in place and preventing it from rolling down to cause injury or damage. Some might confuse it with the electronic parking brake, but Mercedes' P button controls the transmission and is different from the handbrake button. Remember, always come to a complete stop before pressing the P button to avoid damaging the transmission. During regular car maintenance, it's also a good idea to check this button's functionality to ensure it works properly—this habit can significantly extend your car's lifespan.
