[McBethany]

Mercedes-Benz car key usage instructions: 1. Press and hold the lock button to close all windows and lock the car simultaneously. 2. Press and hold the unlock button to unlock the car and lower all windows at the same time. 3. Aim the key at the left front door handle of the car, keeping the distance within one meter, then press the lock button to automatically raise all windows and close the sunroof. 4. Pressing both the lock and unlock buttons together switches between two modes: one mode unlocks the entire car with a single press, while the other mode unlocks only the driver's side with a single press. For the trunk button, press and hold it longer to release.
