Standardising the power windows
The system must be re-standardised after an interruption in the power supply to the power window electronics in the door. The position values for the short-stroke lowering function, position-controlled lowering function in the case of convertible top actuation and enabling for "automatic start-up of window closing" (one-touch function) are redefined. The standardisation process is initiated by continuous actuation of the operating button "Raise window".
- Hold down the "Raise window" button until the window is closed and is switched off by the blockage detection function of the power windows.
Blockage detection function
NOTE: If the window drive encounters resistance during the door window movement, the motor is switched off after a delay of 500 ms.
