Practical Tips, Minor Repairs
Battery
Danger!
Risk of short circuit and fire.
fObserve all warning notes on the battery.
fDisconnect the battery during all work on the
electrical system.
fDo not lay tools or other metal objects on the
battery as they could cause a short circuit
across the battery terminal.
Hydrogen gas generated by the battery
could cause an explosion, resulting in severe
personal injuries.
fDo not expose the battery to an open flame,
electrical spark or a lit cigarette.
Risk of explosion
fDo not wipe the battery with a dry cloth.
fBefore touching the battery, discharge any
static electricity by touching the vehicle.
Risk of severe personal injury and damage to
the fabric, metal or paint.
fWear eye protection.
fDo not allow battery acid to come in contact
with your skin, eyes, fabric or painted surfac-
es.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.
fSpilled electrolyte must be rinsed off at once
with a solution of baking soda and water to
neutralize the acid.
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
chemicals known to the State of California to
cause cancer and reproductive harm.
fAlways protect your skin by washing thorough-
ly with soap and water.
Charge stateA well charged battery will not only prevent start-
ing problems but will also last longer.
In order to avoid unintended battery
discharge
fSwitch off unnecessary electrical loads in city
traffic, on short trips or in a line of traffic.
fAlways remove the ignition key from the igni-
tion switch when leaving the vehicle or
switch ignition off in vehicles with Porsche En-
try & Drive.
fAvoid using the Porsche Communication
Management system and the audio system
when the engine is not running.
Battery carefEnsure that battery is securely mounted.
fKeep terminals and connections clean and
properly tightened. Corrosion can be prevent-
ed by coating the terminals and connections
with petroleum jelly or silicone spray.
fEnsure 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.
fWhen adding water, use only clean containers.
In no case may alcohol (e.g. window cleaner
residues) be permitted to enter the battery.
fUnscrew 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.
fIf 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 be-
ing charged and cause damage.
