Minor Repairs
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switched off or the ignition key is withdrawn.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.

Minor Repairs
313
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.

Minor Repairs
Battery
Danger!
Risk of short circuit and fire, resulting in
serious personal injury or death.
fObserve all warning notes on the battery.
fDisconnect the negative terminal on the
battery during all work on the electrical sys-
tem.
fDo not lay tools or other metal objects on the
battery as they could cause a short circuit
across the battery terminal.
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
fCharge battery in a well vetilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
fDo not expose the battery to an open flame,
electrical spark or a lit cigarette.
Risk of explosion as a result of static charge,
resulting in serious personal injury or death.
fDo not wipe the battery with a dry cloth.
fBefore touching the battery, discharge any
static electricity by touching the vehicle.Risk of serious personal injury or death and
damage to the fabric, metal or paint.
fWear eye protection.
fDo not allow battery acid to come in contact
with your skin, eyes, fabric or painted sur-
faces.
fIf you get electrolyte, which is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a
doctor.
fSpilled electrolyte must be rinsed off at once
with a solution of baking soda and water to
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
fAlways protect your skin by washing
thoroughly with soap and water.
The battery is located in the battery box under the
left front seat.
Charge stateA well charged battery will not only prevent
starting problems but will also last longer.
In order to avoid unintended battery
discharge
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line of traffic.
fAlways remove the ignition key from the igni-
tion switch when leaving the vehicle or
switch ignition off in vehicles with Porsche
Entry & Drive.
fAvoid using the Porsche Communication
Management system and the audio system
when the engine is not running.
Maintenance Note
In the cold season, in particular, or if you mainly
drive only short distances, it may become neces-
sary to recharge the battery from time to time.
