The 12-volt lithium battery is automatically discon-
nected from the vehicle electrical system if the bat-
tery charge state is low. When the 12-volt lithium
battery is discharged, it is impossible to operate the
vehicle. The electrical system is deactivated
temporarily.
e Observe the warning message.
Charging the 12-volt lithium battery:
e Establish driving readiness.
> Please see chapter "Starting, driving and
stopping the vehicle" on page 216.
– or –
e Charging the 12-volt V battery using the
charger.
– or –
e Supply electricity in from another vehicle for at
least 5 minutes.
Then establish operational readiness or charge
the 12-volt battery using the charger.
After establishing operational readiness, charging
the 12-volt lithium battery with a charger (for at
least 10 minutes) or supplying electricity from an
external source, the electrical system is automati-
cally reactivated. The 12-volt lithium battery is au-
tomatically re-connected to the vehicle electrical
supply.
Using a jumper cable, the battery of another vehicle
can be used to supply electricity to the vehicle. Both
batteries must have a nominal voltage level of 12
volts. The capacity (Ah) of the donor battery must
not be substantially less than that of the discharged
battery. The discharged 12-volt lithium battery
must be connected properly to the vehicle electrical
system.
The need to repeatedly supply electricity from an
external source or charge the 12-volt lithium battery
under normal operating conditions may indicate that
the 12-volt lithium battery is damaged.
Safety symbols on the 12 V lithium battery
Consult the Manual
Wear protective goggles
Risk of explosion
Fire, sparks, naked flames and smoking
are prohibited
Avoid sparking and short circuits when
handling cables and electrical devices.
Risk of chemical burns
Electrolyte fluid is highly corrosive: wear
safety gloves and eye protection.
First aid
If electrolyte fluid splashes into your eye,
rinse immediately for a few minutes with
clean water. Immediately seek medical
attention from a doctor. If electrolyte
fluid splashes onto your skin or clothing,
neutralize immediately with soapsuds
and rinse with plenty of water. If you ac-
cidentally drink electrolyte fluid, consult
a doctor immediately.
Keep children away
Disposal
Hand in old batteries at a battery collec-
tion point.
Never dispose of old batteries as house-
hold waste.
Always have maintenance work carried
out by qualified technicians
Never attempt to replace the 12 volt
lithium battery on your own. The 12 V
lithium battery of this vehicle is only to
be replaced with a 12 V lithium battery
explicitly provided for this vehicle by
Porsche. The use of other 12 V lithium or
lead batteries will cause significant dis-
ruptions to or even the total failure of the
electrical system.
Replacing the 12 V lithium battery is
only to be carried out by a qualified spe-
cialist repair shop. Porsche recommends
an authorized Porsche dealer, as they
have trained technicians and the neces-
sary parts and tools.
