Minor Repairs
External Power Supply,
Jump-Lead StartingIf the battery is flat, the battery of another vehicle
can be used for starting or as an external power
supply with the help of jump leads.
Both batteries must be 12 V batteries.
The capacity (Ah) of the do nor battery must not be
substantially less than that of the flat battery.
The flat battery must be connected correctly to
the vehicle’s electrical system.
Warning!
Risk of short circuit, damage and explosion,
resulting in serious personal injury or death.
f Use only jumper cables of adequate diameter
cross-section and fitted with completely
insulated alligator clips.
f Follow all warnings and instructions of the
jumper cable manufacturer.
f When connecting jumper cables, make sure
that they cannot get ca ught in any moving
parts in the engine compartment.
The jumper cables must be long enough so
that neither vehicles nor cables touch another.
f The vehicles must not be in contact, otherwise
current might flow as soon as the positive
terminals are connected.
f The cable clamps must not be allowed to
contact each other when one end of the
jumper cables are connected to a battery. f
Carefully ensure that tools or conductive
jewelery (rings, chains, watch straps) do not
come into contact with the positive jumper
cable or the positive battery post.
f Improper hook-up of jumper cables can ruin
the alternator.
Danger of caustic burns.
f Do not lean over the battery.
Danger of gas explosion.
f Improper use of booster battery to start a
vehicle may cause an explosion, resulting in
serious personal injury or death.
f Keep sources of ignition away from the
battery, e.g. open flame, burning cigarettes or
sparking due to cable contact or welding work.
f A discharged battery can freeze even at
14 °F ( −10 °C). Before connecting jumper
cables, a frozen battery must be thawed out.
+ = Positive terminal for jump-lead starting
– = Ground point for jump-lead startingExternal power supply/jump-lead startingAlways observe the sequence below:
1. Open the cap on the positive terminal for
jump-lead starting ( +).
2. Attach the positive lead first to the positive terminal for jump-lead starting ( +), then to the
positive terminal of the donor battery.
3. Connect the negative lead first to the negative
terminal of the donor battery, then to the
ground point for jump-lead starting ( –).

4. Leave the engine of the donor vehicle running at a higher engine speed.
5. Start the engine. An attempted start using jump leads should
not last more than 15 seconds. Then wait for
at least one minute.
6. Disconnect the negative lead from the ground
point for jump-lead starting ( –) first, then from
the negative terminal of the donor battery.
7. Disconnect the positive lead from the positive terminal of the donor ba ttery first, then from
the positive terminal for jump-lead starting ( +).
8. Close the cap on the posi tive terminal for jump-
lead starting ( +).Charging the batteryAutomotive batteries loose their efficiency when
not in use. The charge available in your battery can
be measured with a battery hydrometer. We
recommend that the battery voltage be tested by
your Porsche dealer who has the appropriate
equipment.
If the car is not driven for prolonged periods, the
battery must be charged at least every 6 weeks.
A discharged battery allo ws rapid formation of
sulfates, leading to premature deterioration of the
plates.
Danger!
Hydrogen gas genera ted 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
frozen battery to thaw out first.
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 doctor.
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
f Always observe the instructions provided by
the charger manufacturer.
1. Connect the charger to the jump-lead starting terminals.
Only plug into the mains and switch the
charger on when it is connected up correctly.
2. Switch on the charger.
3. After charging the battery, first switch off the charger and then disconnect it.
f Please see the chapter “PUTTING VEHICLE
INTO OPERATION” on page 305.
Changing the Remote Control
BatteryNote
f Please observe the regulations for disposing
of batteries.Car keyIf the battery in the remote control becomes too
weak, the message “Replace ignition key battery”
will appear on the multi-function display in the
instrument panel.
The battery should be changed in this case.
