I've been driving a Mercedes-Benz for many years, and the key operations are quite simple. To unlock the vehicle, press the triangular button on the key, and both the doors and trunk will open; to lock the car, press the lock-shaped button to close all doors. Once inside, if it's a keyless start model, simply press the engine start button on the dashboard while stepping on the brake to start the engine. The key also supports one-touch trunk opening: hold the trunk button for three seconds, and the tailgate lifts for easy loading. Daily tips: after locking the car, holding the lock button can automatically raise the windows to prevent theft and rain from entering; the key battery typically lasts about two years, and when it's low, the dashboard will display an alert—replacing the battery is inexpensive and can be done by opening the back cover yourself; avoid placing the key in high-temperature or humid areas to prevent sensor malfunctions. Overall, the Mercedes key is intelligently designed, offering efficiency and safety with every use, especially making outings with kids hassle-free.
