1. Turn on the ignition but don't start the engine.
2. Fully open the driver's side window using the window switch.
3. Once the window is fully open, press and hold the window switch in the "up" position for five seconds.
4. The window will automatically move up and down several times, recalibrating itself.
5. Once the window has finished recalibrating, release the window switch.
6. Repeat steps 2-5 for each of the other windows on the vehicle.
After performing these steps, the electric windows on your Mercedes-Benz should be properly recalibrated.
