Battery The battery is located in the front luggage 
compartment under a black plastic cover.
f Please see the chapter “EMERGENCY OPERA-
TION – PULLING OUT THE IGNITION KEY” on 
Page 74.
f Please see the chapter “EMERGENCY UNLO-
CKING OF THE FRONT LUGGAGE COMPART-
MENT LID” on Page 248.
 Warning!
Risk of short circuit, fire and damage to alternera-
tor and electronic control units, resulting in seri-
ous 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 baki ng 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 po-
wer.
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 and audio 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.
