Battery chargingAutomotive 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 allows rapid formation of sul-
fates, leading to premature deterioration of the
plates.
Danger!
Hydrogen gas generated by the battery
could cause an explosion, resulting in
serious personal injury or death.
fCharge battery in a well ventilated area.
fNever charge a frozen battery. It may explode
because of gas trapped in the ice. Allow a fro-
zen battery to thaw out first.
fIf 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.Note
Your authorized Porsche dealer will be pleased to
advise you about a suitable charger.
fAlways observe the instructions of the charger
manufacturer.
fWhen charging the battery, ensure adequate
ventilation.
1. Check the acid level of a low-maintenance
battery.
2. Connect charger to the jump starting points.
Only plug into the mains and switch the
charger on when it has been correctly
connected up.
3. Switch on the charger.
4. After charging, switch off and disconnect the
charger.
5. Check the acid level of a low-maintenance
battery.
After charging the battery After the battery is connected or the completely
discharged battery is charged, the PSM warning
light lights up on the instrument panel and a
message appears on the multi-purpose display of
the instrument panel to indicate a fault.
This fault can be remedied with a few simple
steps:
1. Start the engine.
To do this, turn the ignition key or the control
unit (on vehicles that have Porsche Entry &
Drive) to ignition lock position 2 twice.
2. Perform a few steering movements to the left
and to the right when vehicle is standing and
drive a short distance in a straight line until the
PSM warning light goes out and the message
is erased from the memory of the multi-
purpose display of the instrument panel.
3. If the warnings does not go out, then:
Drive carefully to the nearest authorized
Porsche dealer.
Have the fault remedied by an authorized
Porsche dealer.
