Closing Roof Module (panoramic Roof) Via Emergency Operation And Initializing Final Deactivation

Information

Information - Closing roof assembly (panorama roof) via emergency operation

If the roof cannot be closed using the rotary switch (e.g. roof jammed), the roof can be closed using the emergency operation mechanism. This deactivates anti-crushing protection and the roof is closed with full engine torque.

NOTE: Before closing the roof assembly using the emergency operation mechanism, make sure that the end positions of the roof cannot be blocked by foreign bodies.

WARNING: Danger of injury. Anti-crushing protection is deactivated in emergency operation mode.

1. Turn the rotary switch to the position "Close roof fully".







2. Keep pressing the emergency operation mechanism -arrow- until the roof is completely closed.

Initializing final deactivation

Final deactivation of the motors must be re-initialized if:
- the battery was disconnected or if an open circuit was detected at terminal 30
- a motor was replaced
- the control unit was replaced
- the lids of the roof assembly were adjusted using the emergency crank

WARNING: Danger of injury. Risk of material damage.

- Do not reach into the moving area of the mechanism when opening and closing the roof assembly.
- Anti-crushing protection is deactivated in emergency operation mode.
- If there is danger, release the rotary switch immediately or activate it in the opposite direction, or switch off the ignition.
- After replacing a motor or moving the lids with the ignition switched off, first close the roof and initialize the limit position.
- Never open the roof assembly without having initialized the limit position of the motors. Danger of collision for the two rear roof segments.

NOTE:
- Activate the switch for at least 5 seconds, but do not activate for more than 40 seconds.
- When the maximum duration of operation (> 40 seconds) is exceeded, the fault code 0409 (Rotary switch emergency button signal is permanently displayed) can be stored in the control unit.
- The fault code can only be detected if the fault memory of the control unit is read out using the Porsche System Tester.
- To initialize the end stops, the lids of the roof assembly are first closed and then opened briefly and closed again. The sun blind is only closed.
- If the lids are already closed before initializing the end stops, these are opened briefly and then closed again for initialization purposes. If the sun blind is already closed, it is not moved during this procedure.
- Initialization must be completed fully as otherwise the roof cannot be operated electrically.
- If initialization is interrupted or terminated, the entire procedure must be repeated.







1. Switch on ignition and turn rotary switch to the position "Close roof fully". Wait until the roof remains in any position.
2. Keep the emergency operation mechanism pressed -arrow- until the sun blind and the roof are completed closed. The sun blind is closed first, then the lids of the roof assembly are completely closed and opened briefly and then closed again.
3. Relieve the seals from strain by briefly opening and then closing the roof again.
4. Read out the fault memory with the Porsche System Tester and erase existing faults.
