Battery The battery is located in the luggage compart-
ment under a black plastic cover.
fPlease see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 76.
fPlease see the chapter “EMERGENCY UNLO-
CKING OF THE LUGGAGE COMPARTMENT LID”
on Page 260.
Warning!
Risk of short circuit, fire and damage to al-
ternerator and electronic control units, re-
sulting in serious personal injury or death.
fObserve all warning notes on the battery.
fDisconnect the negative terminal on the bat-
tery 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
serious personal injury or death.
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 serious personal injury or death 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
surfaces.
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,
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 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:
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line or traffic.
fAlways remove the ignition key from the igni-
tion 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.
fIn 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.

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.
fPlease see the chapter “BATTERY” on
Page 261.
fPlease see the chapter “EMERGENCY UNLO-
CKING OF THE LUGGAGE COMPARTMENT LID”
on Page 260.
Note
fDo 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.
fUse only jumper cables of adequate diameter
cross-section and fitted with completely insu-
lated alligator clips.
fFollow all warnings and instructions of the
jumper cable manufacturer.
fWhen 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.
fThe vehicles must not be in contact, otherwise
current might flow as soon as the positive ter-
minals are connected.
fThe cable clamps must not be allowed to con-
tact each other when one end of the jumper ca-
bles are connected to a battery.
fEnsure that tools or conductive jewelery (rings,
chains, watch straps) do not come into contact
with the positive jumper cable or the positive
battery post.
fImproper hook-up of jumper cables can ruin
the alternator. Danger of caustic burns from escaping acid.
fDo not lean over the battery.
Danger of gas explosion.
fImproper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
fKeep sources of ignition away from the bat-
tery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
fA discharged battery can freeze even at 23 °F/
–5 °C.
Before connecting jumper cables, a frozen
battery must be thawed out.
