An initialization  must be performed:

• In the event of malfunctions, e.g. no one-touch control function, no opening or if available no comfort function is possible.
• After the power window drive has been replaced.
• After work is carried out on the power window mechanism.
• If necessary, after an open circuit, e.g. disconnection of the battery or disconnection of the power supply to the door.
• After the door window glass has been removed and installed or replaced.
• After adjustment work on the door window glass.
• After adjustment work on the convertible top.
• After replacement of seals.

initialization  is performed on the power window switch of the relevant door.

Requirements for correct initialization: 

• Terminal "R" activated.
• Doors and windows closed.
• Sufficient battery voltage; connect charger if necessary.

• Erasure of initialization.
• Reinitialisation.

Erasure of initialization: 

• Open side window fully.
• Actuate power window switch in "Open" position (second switch position) and hold down for between 15 and 20 seconds.

Re-initialisation: 

• Close door window completely
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Close" position (second switch position).
• Open door window glass fully.
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Open" position (second switch position).
• Close door window completely.
• After upper end position is reached, interrupt actuation of power window switch and then hold switch again for approx. 1 second in "Close" position (second switch position).
