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.
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.
fEliminate potential electrostatic charge by
touching the vehicle before touching the
battery.
Charge state A well charged battery will not only prevent
starting problems but will also last longer.
In order to avoid discharging the battery
unintentionally:
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
fAlways remove the ignition key from the
ignition switch when leaving the car.
fAvoid frequent operation of the convertible top
and operation of the Porsche Communication
Management system when the engine is not
running.
In the cold season in particular or if the vehicle is

Practical Tips, Emergency Service
Battery care fEnsure that battery is securely mounted.
fKeep terminals and connections clean and
properly tightened.
Corrosion can be prevented by coating the
terminals and connections with petroleum jelly
or silicone spray.
fEnsure that vent caps are securely tightened to
prevent spillage.
Checking the electrolyte fluid level
Generally, the electrolyte level must be checked
more often in summer than in the winter, and more
often when driving long distances.
fWhen adding water, use only clean containers.
In no case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
fUnscrew 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.
fIf necessary, top up with distilled water.
Do not use acid.
Only fill up to the mark, otherwise the electro-
lyte will overflow when the battery is being
charged and cause damage. Battery charging
Automotive batteries loose their efficiency when
not in use.
The charge available in your battery can be
measured with a battery hydrometer.
We recommend that the battery voltage be tested
by your authorized Porsche dealer who has the
appropriate equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allows rapid formation of
sulfates, leading to premature deterioration of the
plates.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
fCharge battery in a well ventilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a
frozen battery to thaw out first.
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. Slow battery charging
1. Pay attention to all warnings and follow instruc-
tions that come with your battery charger.
2. When charging, ensure adequate ventilation.
3. Remove battery.
Please see the chapter “REMOVING THE
BATTERY” on Page 214.
4. All vent caps should be open.
The fluid level should meet the indicator mark
in each cell.
5. Ensure that charger is switched off – danger of
short circuit!
6. Connect charger cables.
Charger cables must be connected
POSITIVE (+) to POSITIVE (+) and
NEGATIVE (–) to NEGATIVE (–).
7. Switch on charger.
Normally, a battery should be charged at no
more than 10 percent of its rated capacity.
Rated capacity of the battery in your vehicle is
listed on the battery housing.
8. After charging, turn off charger and disconnect
charger cables.
9. Tighten the vent caps and reinstall battery.
Please see the chapter “INSTALLING THE
BATTERY” on Page 215.

Winter operation The capacity and ability of the battery to store
power decreases at low outside temperatures.
Additionally, more power is consumed while
starting, and the headlights, heater, rear window
defogger, etc., are used more frequently.
fLet your Porsche dealer test the battery’s
capacity before winter sets in.
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 will have to recharge the
batteries.
Replacing battery The service life of the battery is subject to normal
wear; it depends greatly on care, climatic condi-
tions, and driving conditions (distances, loads).
fOnly use an original Porsche battery, with the
correct part number, as a replacement.
fPlease observe the disposal instructions for
batteries.
Putting vehicle into operationAfter the battery is connected or after an comple-
tely 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.
fPerform adaptation of the power windows:
