When relieving the pressure in the pressure reservoir for the hydraulic power window on the front door, ensure that the transmitter key is removed.

1. Open front door and remove cover for emergency actuation in side compartment from door lining.
2. Press and hold down emergency actuation (1) until side window is completely lifted.
3. Press and hold down emergency actuation (2) until side window is moved into the catch of the power window.

   Raising and lowering the side window causes the arresting device for the power window to lock preventing the power window lift from moving together.

   Raising and lowering the side window allows the hydraulic oil to flow back from the pressure reservoir to the hydraulic pump for the power window.
