Electrical SystemIn order to avoid damage and faults in electrical or
electronic systems, electrical accessories should
be installed at your authorized Porsche dealer.
fUse only accessories authorized by Porsche.
Warning!
Risk of short circuit and fire, resulting in
serious personal injury or death.
Replacing fuses or relays with engine running
or the ignition on could cause electrical
shock.
fDisconnect the negative terminal on the
battery during all work on the electrical sys-tem.
RelaysRelays should be checked or changed only by an
authorized workshop.
SocketsThe assignment and number of sockets depend
on the respective vehicle equipment.
Electrical accessories can be connected to the
12 V sockets.Note on operation
The sockets and thus the connected electrical
accessories will function even if the ignition is
switched off or the ignition key is withdrawn.
If the engine is not running and the accessories
are switched on, the vehicle battery will be
discharged. Do not operate additional accesso-
ries for more than 5 minutes when engine is off.

Changing fusesIn order to prevent damage to the electrical
system due to short circuits and overloads, the
individual circuits are protected by fuses.
One fuse box is in the engine compartment. Two
additional fuse boxes are located in the outer ends
of the dashboard.
1. Switch off the consumer with the defective
fuse. Before replacing a fuse, switch off all
electrical consumers and remove the ignition
key.
2. Open the fuse-box lid.
3. Remove the corresponding fuse from its slot to
check it using the plastic gripper.
A blown fuse can be identified by the melted
metal strip.
4. Replace only with fuses with the same rated
current. We recommend using genuine
Porsche fuses for replacement.
Note
If a fuse blows repeatedly, please consult an
authorized Porsche dealer immediately, so that
the short circuit can be located and corrected.
fNever try to “repair“ fuses: you may cause
serious damage to other parts of the electrical
system.
