Battery

Danger!
Risk of short circuit and fire.
f Observe all warning notes on the battery.
f Disconnect the battery during all work on the
electrical system.
f Do 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.
f Do not expose the battery to an open flame,
electrical spark or a lit cigarette.
Risk of severe personal injury and damage to
the fabric, metal or paint.
f Wear eye protection.
f Do not allow battery acid to come in contact
with your skin, eyes, fabric or painted surfac-
es.
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 doc-
tor.
f Spilled electrolyte must be rinsed off at once
with a solution of baking soda and water to
neutralize the acid.

Practical Tips, Minor Repairs
Battery posts, terminals and related acces-
sories contain lead and lead compounds,
WWW.MANUALS.WS
chemicals known to the State of California to
cause cancer and reproductive harm.
f Always protect your skin by washing thorough-
ly with soap and water.
Risk of explosion
f Do not wipe the battery with a dry cloth.
f Before touching the battery, discharge any
static electricity by touching the vehicle.
Charge state
A well charged battery will not only prevent start-
ing problems but will also last longer.
In order to avoid unintended battery
discharge
f Switch off unnecessary electrical loads in city
traffic, on short trips or in a line of traffic.
f Always remove the ignition key from the igni-
tion switch when leaving the vehicle or
switch ignition off in vehicles with Porsche En-
try & Drive.
f Avoid using the Porsche Communication
Management system and the audio system
when the engine is not running.
f Please observe the chapter "CHARGING THE
WWW.MANUALS.WS
BATTERY" on Page 325.
Battery care
f Ensure that battery is securely mounted.
f Keep terminals and connections clean and
properly tightened. Corrosion can be prevent-
ed 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 be-
ing charged and cause damage.
