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 doc-
tor.
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 acces-
sories 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 thorough-
ly with soap and water.
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 Eliminate potential electrostatic charge by
touching the vehicle before touching the bat-
tery.
Charge state A well-charged battery prevents starting problems
and has a longer service life.
Traffic density, requirements regarding noise, ex-
haust gas and fuel consumption reduce the engine
speed and, hence, the alternator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid discharging the battery
unintentionally:
f Switch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
f Always remove the ignition key from the igni-
tion switch when leaving the car.
f Avoid frequent operation of the Porsche Com-
munication Management system and audio
system when the engine is not running.
f In the cold season in particular or if the vehicle
is used primarily for short journeys, it may be
necessary to recharge the battery from time to
time.

Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in
winter months, e.g. by the heated rear window,
more frequent use of additional lights, the fans
and the windshield wipers, etc.
f Have the battery checked before the start
of winter.
Maintenance note
Keep the battery well charged to prevent it
from freezing.
A discharged battery can freeze at 23 °F (--5 °C),
but a fully charged battery only freezes at -- 40 °F
(--40 °C).
A frozen battery must always be thawed before
connecting jump leads.
Replacing battery The service life of the batt ery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
f Only use an original Porsche battery, with the
correct part number, as a replacement.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is co nnected or after an exhaus-
tively discharged battery is charged, the multi-
functional PSM light lights up on the instrument
panel and a message appears on the on-board
computer to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
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 multifunctinal PSM light goes out and
the message on the on-board computer
disappears.
3. If the warnings do not disappear, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied.
4. After the warnings disappear: Stop the vehicle in a suitable place.
f Perform adaptation of the power windows:

Emergency Starting with Jumper
Cables If the battery is discharged, e.g. in winter or after
the car has been parked for a long time, the bat-
tery of another car can be used for starting with
the help of jumper cables.
Make sure the voltage of both batteries is the
same. Both batteries must be 12 volt types.
The capacity (Ampere hours, Ah) of the booster
battery must not be substantially less than that of
the discharged battery.
The discharged battery must be correctly con-
nected to the vehicle’s electrical system.
f Please see the chapter “BATTERY” on
Page 239.
f Please see the chapter “EMERGENCY UNLO-
CKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 238.
Note
f Do not try to start the car by pushing or tow-
ing. Damage to the catalytic converters and
other components of the car may result.
Warning!
Risk of short circuit, damage and explosion,
resulting in serious personal injury or death.
f Use only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
f Follow all warnings and instructions of the
jumper cable manufacturer.
f When connecting jumper cables, make sure
that they cannot get caught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
f The vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
f The cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
f Ensure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
f Improper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns from escaping acid.
f
Do not lean over the battery.
Danger of gas explosion.
f Improper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
f Keep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
f A discharged battery can freeze even at 23 °F/
–5 °C.
Before connecting jumper cables, a frozen
battery must be thawed out.

246
Practical Tips, Emergency Service
Connect jumper cables in the following
sequence: Always observe the sequence below:
1. Connect the positive lead (red) to the
positive terminal of the discharged battery
first, then connect it to th e positive terminal of
the donor battery.
2. First connect the negative cable (black) to
the negative terminal of the donor battery, then
connect it to a suitable grounding point on the
vehicle with the discharged battery.
This grounding point must lie as far as possible
from the battery.
For example, a solid metal part or the engine
block are suitable grounding points.
If no suitable grounding points are to be found
on either vehicle, the negative cable must
carefully be connected directly to the negative
terminal of the battery.
If a suitable grounding point is to be found only
on the donor vehicle, the negative cable must
first be connected to the terminal of the
discharged battery, then to the grounding point
of the donor vehicle.
3. Run the engine of the donor car at a higher speed. 4. Start the engine.
An attempted start using jumper cables should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
f Note
Before disconnecting the jumper cables, elec-
trical loads such as the heated rear window
and the heating fan blower should be switched
on (the vehicle’s lights must not be switched
on). This reduces voltage peaks which may oc-
cur when disconnecting the jumper cables.
With the engine running, remove both jumper
cables in reverse order.
