Battery<br />
The battery is located in the front luggage<br />
compartment under a black plastic cover.<br />
f Please see the chapter “EMERGENCY OPERA-<br />
TION – PULLING OUT THE IGNITION KEY” on<br />
Page 74.<br />
f Please see the chapter “EMERGENCY UNLO-<br />
CKING OF THE FRONT LUGGAGE COMPART-<br />

Warning!<br />
Risk of short circuit, fire and damage to alternator<br />
and electronic control units, resulting<br />
in serious personal injury or death.<br />
f Observe all warning notes on the battery.<br />
f Disconnect the negative terminal on the battery<br />
during all work on the electrical system.<br />
f Do not lay tools or other metal objects on the<br />
battery as they could cause a short circuit<br />
across the battery terminal.<br />
Hydrogen gas generated by the battery<br />
could cause an explosion, resulting in<br />
serious personal injury or death.<br />
f Do not expose the battery to an open flame,<br />
electrical spark or a lit cigarette.<br />
f Do not wipe battery with a dry cloth.<br />
Risk of serious personal injury or death and<br />
damage to the fabric, metal or paint.<br />
f Wear eye protection.<br />
f Do not allow battery acid to come in contact<br />
with your skin, eyes, fabric or painted<br />
surfaces.<br />
f If you get electrolyte, which is an acid, in your<br />
eyes or on your skin, immediately rinse with<br />
cold water for several minutes and call a doctor.<br />
f Spilled electrolyte must be rinsed off at once<br />
with a solution of baking soda and water to<br />
neutralize the acid.<br />
Battery posts, terminals and related accessories<br />
contain lead and lead compounds,<br />
chemicals known to the State of California to<br />
cause cancer and reproductive harm.<br />
f Always protect your skin by washing thoroughly<br />
with soap and water.<br />
Risk of explosion as a result of static charge,<br />
resulting in serious personal injury or death.<br />
f Do not wipe the battery with a dry cloth.<br />
f Eliminate potential electrostatic charge by<br />
touching the vehicle before touching the battery.<br />
Charge state<br />
A well-charged battery prevents starting problems<br />
and has a longer service life.<br />
Traffic density, requirements regarding noise, exhaust<br />
gas and fuel consumption reduce the engine<br />
speed and, hence, the alternator output.<br />
However, the large number of electrical loads has<br />
markedly increased the demand for electrical<br />
power.<br />
In order to avoid discharging the battery<br />
unintentionally:<br />
f Switch off unnecessary electrical loads in city<br />
traffic, on short trips or in a line or traffic.<br />
f Always remove the ignition key from the ignition<br />
switch when leaving the car.<br />
f Avoid frequent operation of the Porsche Communication<br />
Management system and audio<br />
system when the engine is not running.<br />
f In the cold season in particular or if the vehicle<br />
is used primarily for short journeys, it may be<br />
necessary to recharge the battery from time to<br />
time.<br />
