54 0 ... Notes On Panorama Glass Roof (Initialization/Normalization/Learning Of Characteristic Curve)







NOTE:
Initialization comprises:
- Normalization
- Learning characteristic curve

The mechanical end positions are recorded and stored during normalization.
The characteristic curve is learnt immediately after normalization.

When the characteristic curve is learnt, the mechanical closing forces of the panorama glass roof are recorded and stored for correct operation of the anti-trapping mechanism.
Initialization is started and implemented by pressing and holding switch in "Lift" direction.
Initialization depends on installed roof system and software used.







NOTE:
Then carry out initialization:
- if the panorama glass roof has been mechanically moved by means of the emergency actuator
- in the event of malfunctions, e.g. no one-touch function, no opening or no comfort function possible
- after disengagement of the drive unit
- after work is carried out on the mechanism of the panorama glass roof
- after the control unit has been replaced
- After replacement of circumferential gasket







WARNING: The anti-trapping mechanism is not active during initialization.

For correct initialization and function, the following conditions must be met:
- Ignition ON
- at room temperature (23°C ± 5°C)
- No direct solar radiation
- only when vehicle is at a standstill
- Fully charged vehicle battery
- in addition, for US vehicles, let engine run to enable key, if necessary







NOTE: Subsequently described processes relate to a completely closed roof system. However, initialization can be started from any position.

Initialization process:
- Move switch in "Lift" direction and hold (roof system moves to "Lift" position)
- In the event of delayed starting or sudden stopping of the panorama glass roof, continue pressing the switch in the "Lift" direction







NOTE: Hold switch depressed for entire process.

- After reaching the fully raised position (A), keep the switch pressed for approx. 30 seconds further (initialization process starts)
- Panorama glass roof moves briefly from lift end position (A) in direction of position (B)
- Shading system (floating headlining) closes completely
- Shading system (floating headlining) opens completely
- Panorama glass roof moves to "Closed" position
- Panorama glass roof then moves to "Open" end position and immediately back to "Closed" position
- After a brief pause, shading system closes completely

NOTE: After panorama glass roof and shading system close completely, initialization is finished. Switch can be released.







E63 only:

NOTE: Hold switch depressed for entire process.

- After reaching the fully raised position (A), keep the switch pressed for approx. 30 seconds further (initialization process starts)
- Panorama glass roof moves briefly from lift end position (A) in direction of position (B)
- Shading system (floating headlining) closes completely
- Shading system (floating headlining) opens completely
- Panorama glass roof moves to "Closed" position
- After a brief pause, shading system closes completely


NOTE: After panorama glass roof and shading system close completely, initialization is finished. Switch can be released.







NOTE:
- If the switch is released in the meantime, the entire procedure must be repeated
- On completion of successful initialization, the corresponding messages in the check control and the control display go out
- Carry out function check (tip function, antitrapping protection and, if necessary, comfort function)
