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 238.
Warning!
Risk of short circuit, fire and damage to al-
ternator and electronic control units, result-
ing 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 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
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 Porsche Com-
munication 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.

Practical Tips, Emergency Service
Battery care fEnsure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened.
Corrosion can be prevented by coating the ter-
minals and connections with petroleum jelly or
silicone spray.
f Ensure that vent caps ar e securely tightened to
prevent spillage.
Checking the electrolyte fluid level
f The acid level should be checked more fre-
quently by a qualified specialist workshop dur-
ing the summer months and in predominantly
warm countries. Battery charging
Automotive batteries loose their efficiency when
not in use.
The charge available in your battery can be meas-
ured with a battery hydrometer.
We recommend that the battery voltage be tested
by your authorized Porsche dealer who has the ap-
propriate equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allows
rapid formation of sul-
fates, leading to premature deterioration of the
plates.
Warning!
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
f Charge battery in a well ventilated area.
f Never charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
f If you get electrolyte, wh ich is an acid, in your
eyes or on your skin, immediately rinse with
cold water for several minutes and call a doc-tor. Slow battery charging
Your authorized Porsche dealer 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.
In this case, always disconnect the negative
lead first, and then the positive lead – risk of
short circuit!.
Reconnect the leads in reverse order.
2. Before charging, cold batteries must be warmed up indoors.
3. Frozen batteries must be thawed out first before being charged.
4. When charging, ensure that there is adequate ventilation.
5. Connect the charger to the battery. Only plug into the mains and switch the
charger on when it is connected up correctly.
6. Switch on the charger.
7. After charging, switch off the charger first and then disconnect it.

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.
