Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may
cause serious personal injury or death.
fThe engine compartment of any motor vehicle
is a potentially hazardous area. If you are not
fully familiar with proper repair procedures, do
not attempt the adjustments described on the
following pages.
This caution applies to the entire vehicle.
fO n l y w o r k o n y o u r v e h i c l e o u t d o o r s o r i n a w e l l
ventilated area.
fEnsure that there are no open flames in the
area of your vehicle at any time when fuel
fumes might be present. Be especially cau-
tious of such devices such as hot water heat-
ers which ignite a flame intermittently.
fBefore working on any part in the engine com-
partment, turn the engine off and let it cool
down sufficiently. Hot engine compartment
components can burn skin on contact.
fBe alert and cautious around engine at all
times while the engine is running.
If work has to be performed with the engine
running, always set the parking brake, and
make sure the shift lever is in neutral or the se-
lector lever is in position P.fIn particular, be very careful to ensure that
items of clothing (ties, shirt, sleeves etc.), jew-
elry, long hair, hand or fingers cannot get
caught in the engine-compartment blower, fan,
belts or other moving parts.
The radiator and radiator fans are in the front
of the car.
The fans can start or continue running as a
function of temperature, even with the engine
switched off.
Carry out work in these areas only with the en-
gine off and exercise extreme caution.
fYour Porsche is equipped with an electronic ig-
nition system. When the ignition is on, high volt-
age is present in all wires connected with the
ignition system; therefore, exercise extreme
caution when working on any part of the engine
while the ignition is on or the engine is running.
fAlways support your car with safety stands if it
is necessary to work under the car.
Jacks are not suitable for this kind of work.
fWhen working under the car without safety
stands but with the wheels on the ground,
make sure the car is on level ground, the
wheels are blocked, and that the engine can-
not be started.
Remove the ignition key.fDo not smoke or allow an open flame around
the battery or fuel.
Keep a fire extinguisher close at hand.
fIncomplete or improper servicing may cause
problems in the operation of the car. If in doubt
about any servicing, have it done by your au-
thorized Porsche dealer.
Improper maintenance during the warranty pe-
riod may affect your Porsche warranty cover-
age.
fSupplies of fluids, e.g. engine oil, brake fluid or
coolant, are hazardous to your health.
Keep these fluids out of children’s reach and
dispose of them in accordance with the appro-
priate regulations.
fSome countries require additional tools and
special spare parts to be carried in your vehi-
cle.
Please make enquiries before driving abroad.
Working in the engine compartmentHave the necessary work in the engine compart-
ment done by a qualified specialist workshop.
We recommend that you use your authorized
Porsche dealer for carrying out this work.

Battery
Warning!
Risk of short circuit and fire.
fObserve all warning notes on the battery.
fDisconnect the battery during all work on the
electrical system.
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 severe
personal injuries.
fDo not expose the battery to an open flame,
electrical spark or a lit cigarette.
fDo not wipe battery with a dry cloth.
Risk of severe personal injury 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 surfac-
es. 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 doc-
tor.
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 thorough-
ly with soap and water.
Risk of explosion as a result of static charge.
fDo not wipe the battery with a dry cloth.
fEliminate potential electrostatic charge by
touching the vehicle before touching the bat-
tery.

Practical Tips, Emergency Service
Charge stateA well-charged battery prevents starting problems
and has a longer useful life.
Traffic density, speed limits, requirements
regarding noise, exhaust gas and fuel consump-
tion reduce the engine speed and, hence, the
generator output.
However, the large number of electrical loads has
markedly increased the demand for electrical
power.
In order to avoid unintended battery
discharge
fSwitch off unnecessary electrical loads in city
traffic, on short trips and in queues.
fAlways withdraw the ignition key when leaving
the vehicle.
fAvoid frequent operation of the Porsche
Communication Management system when the
engine is not running.
Battery carefKeep battery surface clean and dry.
fEnsure that cell plugs and terminal clamps are
firmly secured.
Checking acid level
The acid level should be more frequently checked
by a qualified specialist workshop during the
summer months and in predominantly warm
countries.
Charging the battery
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
1. Always observe the instructions of the charger
manufacturer.
Depending on the type of charger, the battery
may have to be disconnected. Extremely
important: disconnect the negative cable first,
and then the positive cable – danger of short
circuit!
Reconnection must be carried out in reverse
order.
2. Before charging, cold batteries must be
warmed up indoors.
3. Frozen batteries must not be charged. They
must be replaced with a new battery.
4. When charging, ensure adequate ventilation. 5. Connect charger to the battery.
Only plug into the mains and switch the
charger on when it has been correctly
connected up.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in severe
personal injuries.
fCharge battery in a well ventilated 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.
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 doc-tor.

237
Winter drivingThe capacity and ability of the battery to store
power decreases at low outside temperatures.
Moreover, the battery is more heavily loaded in the
winter months, e.g. by the heated rear window,
the more frequent use of additional lights, the
blower and the windshield wipers, etc.
fHave the battery checked before winter
begins.
Keep the battery well charged to prevent it from
freezing.
A discharged battery can freeze even at
23°F/-5 °
C, but a fully charged one only freezes at
-40°F/-40 °C.
Storing up the vehicleIf the vehicle stands for long periods in the garage
or workshop, the doors and lids should be closed.
fPlease observe the chapter “EMERGENCY
UNLOCKING OF THE FRONT LUGGAGE
COMPARTMENT LID” on Page 234.
fWithdraw the ignition key and, if necessary,
disconnect the battery.
When the battery is disconnected, the
alarm system ceases to function!
Even if you put your vehicle out of operation, the
battery still discharges.
fThe battery must be charged, i.e. connected
to a charger, approximately every 6 weeks in
order to preserve functioning.
Always observe the instructions of the charger
manufacturer.
fStore a battery that has been removed in a
dark, cool place, but not subject to frost.
Replacing the batteryThe battery is subject to normal wear: its service
life depends heavily on the care you give it,
climatic conditions and the conditions of use
(distances, loads).
It is not possible to use the details on the battery
case to determine a comparable battery that
meets all the specific requirements of Porsche.
fUse only a battery that meets the specific
requirements of your vehicle as a replacement.
We recommend that you use an Orignal
Porsche battery.
fPlease observe the disposal instructions for
batteries!
