Minor Repairs
Electrical SystemIn order to avoid damage and faults in electrical or
electronic systems, electrical accessories should
be installed at a qualified specialist workshop. We
recommend that you have an authorized Porsche
dealer to do this work, as they have the trained
workshop personnel and the necessary parts and
tools for this type of work.
fUse only accessories approved by Porsche.
Warning!
Risk of short circuit and fire, resulting in
serious personal injury or death.
Replacing fuses or relays with the engine
running or the ignition on could cause
electrical shock.
f Disconnect the negative terminal on
the battery during all work on the
electrical system.
f Please see the chapter “BATTERY” on page 303.
RelaysRelays should be checked or changed only at an
authorised workshop.
Plug socket in glove compartmentSocketsElectrical accessories can be connected to the
12 V sockets.
You will find sockets in the glove box, in the front
and rear center consoles and in the luggage
compartment, depending on vehicle equipment.

Minor Repairs

Plug socket in the storage tray between the front seatsNote
The maximum electrical load of a socket is 20 A,
but only if no other loads are switched on. Do not
exceed 10 A per socket if several loads are
operating simultaneously.
Plug socket in the storage tray between the rear seatsNote on operation
The sockets and thus the connected electrical
accessories function even if the ignition is
switched off or the ignition key is removed.
If the engine is not running and the accessories
are switched on, the vehicle battery will
be discharged.
The power supply is interrupted after 30 minutes
to protect the vehicle battery. The ignition must
then be switched on once in order to switch the
load back on again.
Plug socket in the luggage compartmentPlug sockets in the storage tray of the large
center console in the rear of the vehicle
Two additional plug sockets are located in the
storage tray of the large center console in the rear
of the vehicle, if the re levant vehicle equipment is
fitted.

Battery
Danger!
Risk of short circuit and fire, resulting in
serious personal injury or death.
f Observe all warning notes on the battery.
f Disconnect the negative terminal on the
battery during all work on the electrical
system.
f Do 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.
f Charge battery in a well vetilated area.
f Never charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a
frozen battery to thaw out first.
f Do 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.
f Do not wipe the battery with a dry cloth.
f Before 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.
f Wear eye protection.
f Do not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
f If 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.
f Spilled electrolyte must be rinsed off at once
with a solution of baki ng soda and water to
neutralize the acid.
Battery posts, terminals and related
accessories contain lead and lead
compounds, chemicals known to the State of
California to cause cancer and reproductive
harm.
f Always 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
f Switch off unnecessary electrical loads in city
traffic, on short trips or in a line of traffic.
f Always remove the ignition key from the
ignition switch when leaving the vehicle or
switch ignition off in vehicles with Porsche
Entry & Drive.
f Avoid using the Porsche Communication
Management system and the audio system
when the engine is not running.
Maintenance note
In the cold season, in part icular, or if you mainly
drive only short distances, it may become
necessary to recharge the battery from time to
time.

304
Minor Repairs
Battery carefEnsure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened. Corrosion can be
prevented by coating the terminals and
connections with petroleum jelly or silicone
spray.
f Ensure that vent caps ar e securely tightened to
prevent spillage.
Checking the electrolyte fluid level
(only on low-maintenance batteries)
Generally, the electrolyte level must be checked
more often in summer than in the winter, and more
often when driving long distances.
f When adding water, use only clean containers.
In no case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
f Unscrew and open the filler vent caps of each
cell.
With the car on a level surface, the fluid level
should meet the indicator mark in each cell.
f If necessary, top up with distilled water. Do not
use acid. Only fill up to the mark, otherwise the
electrolyte will overflow when the battery is
being charged and cause damage.
Winter operationDuring the winter months, battery capacity tends
to decrease as temperatures drop. Additionally,
more power is consumed while starting, and the
headlights, heater, rear window defogger, etc.,
are used more frequently.
f Let your Porsche dealer test the battery's
capacity before winter sets in.Vehicle storageIf the car stands for long periods in the garage or
workshop, the doors and lids should be closed.
f Remove the ignition key and, if necessary,
disconnect the battery.
Notes on operation
f When the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
f Lock the vehicle and unlock it again.
Alarm system, central locking
f The status of the central locking and alarm
system is not changed by disconnecting the
battery. Maintenance notes
Even if you put your vehicle out of operation, the
battery still discharges.
The battery will discharge more quickly if your
vehicle is not driven on a daily basis over a
distance of several miles. The more often you
drive your vehicle, and
the longer the distance
driven on each trip, the more opportunity the
vehicle‘s charging system w ill have to recharge the
batteries.
f To preserve its efficiency, charge the battery
about every 6 weeks.
f Check the battery acid level and top off with
distilled water if necessary.
f Store a battery that has been removed in a
dark, cool place, but not subject to freezing.

Minor Repairs
305
Replacing the batteryThe service life of the battery is subject to normal
wear; it depends greatly on care, climatic
conditions, and driving conditions (distances,
loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement. Only
this battery meets the spec ific requirements of
the vehicle.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after a fully
discharged battery is charged, the PSM warning
light lights up on the instrument panel and
a message appears on the multi-function display
in the instrument panel to indicate a fault.
This fault can be corrected with a few
simple steps:
1. Start the engine. To do this, turn the igni tion key or the control
unit (on vehicles with Porsche Entry & Drive)
to ignition lock position 2, twice .
2. With the vehicle stationary, perform a few steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-function
display in the instrument panel.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer to have the fault corrected.
4. After the warnings go out: Stop the vehicle in a suitable place.
5. Store the end position for the power windows. For information on storin
g the end positions for
the power windows:
f Please see the chapter “STORING END
POSITION OF THE DOOR WINDOWS AFTER
CONNECTING THE VEHICLE BATTERY” on
page 88.
6. Teach tires on vehicles with Tire Pressure Monitoring.
For information on teaching the Tire Pressure
Monitoring system:
f Please see the chapter “TIRE PRESSURE
MONITORING (TPM)” on page 127.
7. Store end position on vehicles with a slide/ tilt roof.
For information on storing the end position for the
slide/tilt roof:
f Please see the chapter “STORING END
POSITION OF THE SLIDE/TILT ROOF” on
page 90.
