Battery
The battery is located in the luggage compart-
ment under a black plastic cover.
f Please see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on
Page 76.
f Please 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.
f Observe all warning notes on the battery.
f Disconnect the negative terminal on the bat-
tery during all work on the electrical system.
f Do 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.
f Do not expose the battery to an open flame,
electrical spark or a lit cigarette.
f Do not wipe battery with a dry cloth.
Risk of serious personal injury or death and
damage to the fabric, metal or paint.
f Wear eye protection.
f Do not allow battery acid to come in contact
with your skin, eyes, fabric or painted
surfaces.
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 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.
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 convertible top
and operation of the Porsche Communication
Management 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.
