Practical Tips, Emergency Service
Exercise Extreme Caution when
Working on your Vehicle
Danger!
Ignoring the following instructions may cau-
se 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 hea-
ters 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.), je-
welry, 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 vol-
tage 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. The jack
supplied with the car is not adequate for this
purpose.
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 in close reach.
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.
Please make enquiries before driving abroad.

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 convertible top
and 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 Porsche partner 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.

Practical Tips, Emergency Service
Putting vehicle into operationAfter the battery is connected 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 qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear, stop the vehicle
in a suitable place.
5. Perform adaptation of the power windows:
Please observe the chapter “STORING END
POSITION OF THE WINDOWS” on Page 29.Ignition key/ignition lock

Practical Tips, Emergency Service
Jump lead startingfPlease observe the chapter “EMERGENCY
UNLOCKING OF THE FRONT LUGGAGE
COMPARTMENT LID” on Page 228.
fPlease observe the chapter “BATTERY” on
Page 229.
If the battery is flat, the battery of another vehicle
can be used to start the car with the aid of jump
leads.
Both batteries must be 12 volt types. The
capacity (Ampere hours, Ah) of the donor battery
must not be substantially less than that of the
discharged battery.
The discharged battery must be correctly
connected to the vehicle’s electrical system.
Warning!
Risk of damage and injury due to short
circuit.
fUse only standard jump leads with sufficient
cross section and completely insulated
clamps.
Follow the jump lead manufacturer’s instruc-
tions.
fRoute the jump leads so that they cannot be
caught by moving parts in the engine compart-
ment.
The vehicles must not be in contact, otherwise
current might flow as soon as the positive
terminals are connected.
fCarefully ensure that conductive jewellery
(rings, chains, watch straps) do not come into
contact with live parts of the vehicle.
Danger of caustic burns.
fDo not lean over the battery.
Danger of gas explosion.
fKeep sources of ignition, e.g. naked flame,
burning cigarettes or sparks due to cable
contact, away from the battery.
fBefore connecting jump leads, it is essential to thaw out a frozen battery.
Connecting jump leadsAlways observe the sequence below:
1. Connect the red positive lead to the positive
terminal of the discharged battery first, then
connect it to the positive terminal of the donor
battery.
2. First connect the black negative cable 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 jump leads should
not last more than 15 seconds. Then allow a
waiting period of at least one minute.
5.Note
Before disconnecting the jump leads, electrical
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 occur when
disconnecting the jump leads.
With the engine running, remove both jump
leads in reverse order.
