Information
The battery will run down even if the vehicle is out of
operation.
e
To maintain its functionality, charge the battery
approximately every six weeks or connect it to
a trickle charger suitable for batteries with AGM
technology (Absorbent Glass Mat).
Porsche recommends the charger and charge
maintenance unit from Porsche Tequipment.
e
Store the removed battery in a dark, cool place
where there is no risk of frost.

2. Remove cover in luggage compartment.
g Refer to chapter "Sealing defective tires" on
page 237.
3. Connect red positive charger cable to positive
battery terminal A.
4. Connect black negative charger cable to ground
point B.
5. Switch on charger.
6. After charging, switch off charger before discon-

197.
e
For suitable charger recommendations: Contact
an authorized Porsche dealer.
Jump starting
If the battery is flat, the battery of another vehicle
can be used with jumper cables for starting and as
an external power supply. Both batteries must be
12 V batteries. The capacity (amp hour Ah) of the
donor battery must not be substantially less than that
of the discharged battery. The discharged battery
must be properly connected to the vehicle electrical
system.
g Refer to chapter "Battery" on page 194.
Repeated jump starting under normal operating con-
ditions can indicate a damaged battery.
Unsuitable jumper cables
WARNING
and following incorrect
procedures
Starting the vehicle using unsuitable jumper cables
or following incorrect procedures can cause short
circuits. Short circuits can cause a fire.
e
Use only standard jumper cables with a sufficient
cross-section and fully insulated clamps. Follow
the instructions provided by the jumper cable
manufacturer.
e
The vehicles must not touch, otherwise current
may flow as soon as the positive terminals are
connected.
e
Ensure that conductive jewelry (e.g. rings,
chains, watch straps) do not come into contact
with conductive parts of the vehicle.
e
Never connect jumper cables directly to the bat-
tery or other electrical components. Only con-
nect jumper cables to the jump-lead starting
terminals.
