A diagram on the inside of the lid shows the
layout of the fuses and relays (A).
Additional relays and fuses are located in the
driver's footwell, next to the steering column .
Because of the danger of short-circuits, al-
ways disconnect the battery before begin-
ning work on the electrical system.
If the battery is disconnected, the data for the
engine electronics stored in the control unit are
erased . When the battery is reconnected, the
engine should be run for approx . 10 minutes to
allow the control unit to re-acquire these data.
During this period, the engine may idle unevenly
or too fast.
Changing a Fuse
Switch off the affected system.
You can detect a blown fuse by the melted met-
al strip.
To test or replace a fuse, it must be removed
from the spring clamp using the tool provided
(C). As a replacement, use only fuses of the
same rating.
Note :
Should a fuse blow several times, an Olllcia l
Porsche Centre should be consulted.
It is advisable to carry spare fuses of the differ -
ent ratings in the vehicle.
In the main fuse box there are spaces for spare
fuses (B).
