67 62 ... Notes On Initializing Power Window
Initialization is performed on the power window switch of the relevant door.
Initialization comprises:
- Normalization
- Learning characteristic curve
With normalization, the mechanical end stops of the power window are recorded and stored.
The characteristic curve is learnt immediately after normalization.
When the characteristic curve is learnt, the mechanical closing forces of the power window are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization, i.e. normalization and learning of characteristic curve, is performed in a continuous operation.
An initialization must be performed:
- In the event of malfunctions, e.g. no one-touch function, no opening or no comfort function possible.
- After the power window drive or door module has been replaced.
- After work is carried out on the power window mechanism.
There is no anti-trapping protection during initialization.
Operating sequence for initialization:
- Move side window into lower end position.
- Press switch into "Open one-touch operation" (second switch position) for approx. 15 to 25 s and hold down.
- Release switch, then immediately press into "Close one-touch operation" (second switch stage) and hold down.
- The side window now moves to the lower end position and then back to the upper end position.
Initialization is completed once the side window has returned to the upper end position.
Carry out function check (one-touch function, anti-trapping protection and, if necessary, comfort function).

- • You smell fuel, burning insulation, or see smoke.
- • Brakes feel soft, pull hard to one side, or make grinding noises.
- • The engine overheats, stalls repeatedly, or misfires under load.
- • You are missing required tools, torque specs, or safe lifting equipment.
- • You are not confident in the next step or safety outcome.
