Overload protection

If the central locking system is operated more than ten times within a minute, further operation is blocked for 30 seconds.

Load switch-off after 2 hours or 7 days

If the ignition key is removed, loads which are switched on or are in standby mode (such as the luggage compartment light, interior light and radio) are automatically switched off after approx. 2 hours.

If the vehicle is not started or unlocked with the remote control within 7 days, the remote control standby function is switched off (to save the vehicle battery).

Replacing fuses

In order to prevent damage to the electrical system due to short circuits and overloads, the individual circuits are protected by fuses. The fuse box is located in the driver's footwell.

Switch off the load with the defective fuse.

2. Pull off plastic cover at the finger hole (arrow). The fuse plan and instructions for emergency unlocking of the luggage compartment lid can be found on the inner side of the cover.

3. Remove the corresponding fuse from its slot using the plastic gripper A in order to check it. A blown fuse can be identified by the melted metal strip.

4. Replace only with fuses of the same rating.


> If a fuse blows repeatedly consult an authorized Porsche dealer.

> Never try to "repair" fuses: you may cause serious damage to other parts of the electrical system.

Emergency unlocking of the luggage compartment lid

If the battery is discharged, the lid can be opened only with the aid of a donor battery.

Unlocking lid

1. Use the key to unlock the vehicle at the door lock.

2. Remove plastic cover over the fuse box.

3. Pull out positive terminal A in the fuse box.

4. Use a jumper cable to connect the positive terminal of the donor battery with positive terminal A in the fuse box.


If the vehicle was locked, the alarm horn will sound when the negative cable is connected.

5. Use the second jumper cable to connect the negative terminal of the donor battery with latch striker B.

6. Unlock the luggage compartment lid with the remote control.

The alarm system is switched off.

7. Disconnect the negative cable first, then the positive cable.

8. Push the positive terminal A into the fuse box and push on the plastic fuse box cover.


The engine cannot be started with this method.
