Maintenance notes
Even if you put your vehicle out of operation, the

battery about every 6 weeks.
f Check the battery acid level and top up with
distilled water if necessary.
f Store a battery that has been removed in a
dark, cool place, but not subject to frost.
Replacing the battery
The battery is subject to normal wear: its service
life depends greatly on the care you give it,
climatic conditions and the conditions of use
(distances, loads).
It is not possible to use the details on the battery
case to determine a comparable battery that
meets all the specific requirements of Porsche.
f Only replace the battery with one that satisfies
the specific requirements of your vehicle.
We recommend that you use a genuine
Porsche battery.
f Please observe the disposal instructions for
batteries.
Putting vehicle into operation
After the battery is connected or after an exhaus-
tively 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 with Porsche Entry & Drive) to
ignition lock position 2 twice.
2. With the vehicle stationary, perform a few
steering movements to the left and right and
then drive a short distance in a straight line
until the PSM warning light goes out and the
message is erased from the multi-purpose
display of the instrument panel.
3. If the warnings do not disappear, then:
Drive carefully to the nearest qualified
specialist workshop.
Have the fault remedied.
4. After the warnings disappear:
Stop the vehicle in a suitable place.
