What does the Mercedes SET button mean?

Mercedes SET button means to activate the cruise control. Here is more information about the SET button: 1. The SET button is the speed control button for Mercedes cruise control function. When the car needs to set cruise control, after increasing the car to a certain speed, pressing the SET button can adjust the cruise speed to the current speed. Stepping on the brake pedal will cancel the cruise control. 2. The function of the SET button is to adjust the tire pressure of all four tires to the standard pressure. After long pressing SET for three seconds while watching the speedometer, a symbol with an exclamation mark in brackets will appear. After hearing a beep, the tire pressure of all four tires will be adjusted to the calibrated value. 3. If a tire leaks during driving causing incorrect tire pressure, the system will automatically alarm. The working principle of the cruise control system is simply that the cruise control component reads the pulse signal from the speed sensor and compares it with the set speed, then issues instructions to mechanically adjust the throttle opening through the servo to increase or decrease, so that the vehicle always maintains the set speed.
As a Mercedes owner with over a decade of driving experience, I'm very familiar with the SET button. Located on the steering wheel or steering column, it's primarily used for the cruise control system. After starting the vehicle, activate the cruise control button and press SET to lock in the current speed, then use the +/- buttons to adjust - making long-distance driving more effortless and fuel-efficient. On my older Mercedes model, SET also resets the trip odometer or sets trip information; it's wise to glance at the manual before operating. For safety, I recommend using cruise control only on elevated roads or highways - avoid it in urban traffic, especially in complex road conditions where braking issues may arise. The SET function remains consistent across different Mercedes models like C-Class and E-Class. Prolong button lifespan by periodically cleaning dust, as prolonged use may cause malfunctions.
I'm a car enthusiast and quite knowledgeable about the new Mercedes models. The SET button typically represents the setting function. When used with cruise control, pressing it once locks the current speed, and you can fine-tune it with the +/- buttons. On highways, you don't need to keep your foot on the accelerator—it feels like autonomous driving, which is pretty awesome. In some newer Mercedes models, the SET function is integrated into the touchscreen or voice system, allowing you to adjust ACC following distance or HUD display. I recommend beginners try operating it on open roads first to avoid accidental touches that could cause danger. The button is usually located on the side of the steering wheel, with clear lighting prompts, making it easy to use. Occasionally, it might malfunction, such as when the button gets damp during rainy seasons—just dry it promptly.
