Removing motor for height adjustment

> Always observe the safety regulations for handling airbag units. Refer to 69 AW Safety regulations for handling airbags and.. - as of MY 2003 (All Models).

> The airbag unit must always be stowed so that the airbag opening faces upwards!

> If removed for an extended period, the airbag unit must be kept in a locked place!

> Switch off ignition and leave ignition key in. Disconnect battery. Route or isolate the ground strap so that all contact with a ground carrier (e. g. body, seat frame) is avoided. Refer to 90 IN Work instructions after disconnecting the battery - as of MY 2003 (All Models Except Cayenne S TIO Titan).

> After the battery is disconnected, always wait for 1 minute before disconnecting the airbag plugs.

Note. Before removing the motor, move seat height up fully, then lower it slightly again so that the height adjustment is not tensioned.

Note. Only disconnect the plug axially from the positioning motor. Otherwise the retaining lugs can break off and a secure plug lock cannot be guaranteed.

initializing control unit for memory seat adjustment

1. Switch on ignition.

2. Use seat adjustment switch to tilt backrest completely forwards (as far as the stop).

3. Keep switch pressed in this position (approx. 5 seconds) until you hear a signal tone on the instrument cluster. The control unit is now initialized.

Locking control unit for memory seat adjustment

The Cayenne comes with either a large or small memory package, depending on the vehicle equipment. The corresponding memory package must therefore be locked in the control unit following initialization.

> The control unit can be locked only once. Given this, the memory package that corresponds to the vehicle equipment must be selected before locking the control unit.

> If the small memory package is inadvertently locked on a vehicle with a large memory package, only the scope of the small memory package can be monitored (no electrical steering column or belt height adjustment monitoring!). This does not impair steering column or belt height adjustment.

Note. The control units for the driver's and front passenger's seat are identical.

1. The control unit for the passenger's side is automatically coded correctly and does not need to be locked.

1. The control units cannot be switched, e. g. a passenger control unit that has already been locked cannot be installed on the driver's side.

1. It is not possible to switch driver's sides in vehicles with different memory packages.

1. Connect the Porsche System Tester and switch on the ignition.

2. Select Cayenne as the vehicle type and confirm with the >> key.

3. Use the ↑↓ keys to select Driver's seat memory or Passenger's seat memory and confirm your selection by pressing >>.

4. Use the ↑↓ keys to select Large memory package or Small memory package and confirm by pressing >>.

5. Select Lock in the function selection and confirm with the F8 key.

6. To complete the locking process, switch the ignition off and on and then erase the fault memory.
