Important safety notes

G
WARNING
During the charging process, a battery produ-
ces hydrogen gas. If a short circuit occurs or
sparks are created, the hydrogen gas can
ignite. There is a risk of an explosion.
Make sure that the positive terminal of a
R
connected battery does not come into con-
tact with vehicle parts.
Never place metal objects or tools on a bat-
R
tery.
It is important that you observe the descri-
R
bed order of the battery terminals when
connecting and disconnecting a battery.
When jump-starting, make sure that the
R
battery poles with identical polarity are
connected.
It is particularly important to observe the
R
described order when connecting and dis-
connecting the jump leads.
Never connect or disconnect the battery
R
terminals while the engine is running.
G
WARNING
Battery acid is caustic. There is a risk of injury.
Avoid contact with skin, eyes or clothing. Do
not inhale any gases released from the bat-
tery. When carrying out maintenance work on
the battery, wear acid-resistant protective
clothing, particularly protective eyewear, pro-
tective gloves and an apron. Do not lean over
the battery. Keep the batteries out of the
reach of children.
If you come into contact with battery acid,
observe the following:
immediately rinse battery acid off skin thor-
R
oughly with clean water and seek immedi-
ate medical attention.
if you get battery acid in your eyes, rinse
R
them thoroughly with clean water immedi-
ately. Consult a doctor without delay.
G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly explo-
sive gases of a battery. There is a risk of an
explosion.
Before handling the battery, touch the vehicle
body to remove any existing electrostatic
build-up.
A highly explosive mixture of gases is gener-
ated while charging the battery and jump-
starting.
Always make sure that neither you nor the
battery are electrostatically charged. An elec-
trostatic build-up may occur, for example:
if synthetic clothing is worn
R
if clothing is rubbed on the seat
R
if you pull or push the battery over carpets
R
or other synthetic materials
if you wipe the battery with a cloth

Environmental note
Batteries contain pollutants.
It is against the law to dis-
pose of them along with
household waste. They must
be collected separately and
recycled in an environmen-
tally responsible manner.
Dispose of batteries appro-
priately. Hand over dis-
charged batteries to a quali-
fied specialist workshop.
Transport and store full bat-
teries in an upright position.
When transporting batteries,
