Replacing 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.
