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.
Replacing fuses or relays with engine running
or the ignition on could cause electrical
shock.
fDisconnect the battery during all work on the electrical system.
RelaysRelays should be checked or changed only by an
authorized workshop.Alarm system, central lockingThe status of the central locking and alarm system
is not changed by disconnecting the battery.
When the battery is disconnected, the alarm
system ceases to function.
SocketsElectrical accessories can be connected to the
12 V sockets.Note on operation
The sockets and thus the connected electrical ac-
cessories function even if the ignition is swi tched
off or the ignition key is withdrawn.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.

Changing fusesIn order to prevent damage to the electrical
system due to short circuits and overloads, the in-
dividual 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 of the same rating.
Note
If a fuse blows repeatedly, please consult an au-
thorized Porsche dealer immediately, so that the
short circuit can be located and corrected.
Never try to “repair“ fuses: you may cause serious
damage to other parts of the electrical system.
