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.

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.

4. Replace only with fuses of the same rating.

Note

> 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 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.
