Minor Repairs
Battery care
f
Ensure that battery is securely mounted.
f
Keep terminals and connections clean and
properly tightened. Corrosion can be
prevented by coating the terminals and
connections with petroleum jelly or silicone
spray.
f
Ensure that vent caps are securely tightened to
prevent spillage.
Checking the electrolyte fluid level
(only on low-maintenance batteries)
Generally, the electrolyte level must be checked
more often in summer than in the winter, and more
often when driving long distances.
f
When adding water, use only clean containers.
In no case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
f
Unscrew and open the filler vent caps of each
cell.
With the car on a level surface, the fluid level
should meet the indicator mark in each cell.
f
If necessary, top up with distilled water. Do not
use acid. Only fill up to the mark, otherwise the
electrolyte will overflow when the battery is
being charged and cause damage.
Winter operation
During the winter months, battery capacity tends
to decrease as temperatures drop. Additionally,
more power is consumed while starting, and the
headlights, heater, rear window defogger, etc.,
are used more frequently.
f
Let your Porsche dealer test the battery's
capacity before winter sets in.
Vehicle storage
If the car stands for long periods in the garage or
workshop, the doors and lids should be closed.
f
Remove the ignition key and, if necessary,
disconnect the battery.
Notes on operation
f
When the battery is disconnected, the alarm
system ceases to function.
If the vehicle was locked before the battery
was disconnected, the alarm will be triggered
when the battery is reconnected.
To deactivate the alarm system:
f
Lock the vehicle and unlock it again.
Alarm system, central locking
f
The status of the central locking and alarm
system is not changed by disconnecting the
battery.
Maintenance notes
Even if you put your vehicle out of operation, the
battery still discharges.
The battery will discharge more quickly if your
vehicle is not driven on a daily basis over a
distance of several miles. The more often you
drive your vehicle, and the longer the distance
driven on each trip, the more opportunity the
vehicle‘s charging system will have to recharge the
batteries.
f
To preserve its efficiency, charge the battery
about every 6 weeks.
f
Check the battery acid level and top off with
distilled water if necessary.
f
Store a battery that has been removed in a
dark, cool place, but not subject to freezing.
