G WARNING
Work carried out incorrectly on the battery
can lead, for example, to a short circuit and
thus damage the vehicle electronics. This can
lead to function restrictions applying to
safety-relevant systems, e.g. the lighting
system, ABS (anti-lock braking system) or
®
ESP (Electronic Stability Program). The
operating safety of your vehicle may be
restricted. You could lose control of the
vehicle, for example:
braking
R
in the event of abrupt steering maneuver
R
and/or when the vehicle's speed is not
adapted to the road conditions
There is a risk of an accident.
In the event of a short circuit or a similar
incident, contact a qualified specialist
workshop immediately. Do not drive any
further. You should have all work involving the
battery carried out at a qualified specialist
workshop.
G
WARNING
Electrostatic build-up can lead to the creation
of sparks, which could ignite the highly
explosive 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.
The highly flammable gas mixture forms when
charging the battery as well as when jump-
starting.
Always make sure that neither you nor the
battery is electrostatically charged. A build-
up of electrostatic charge can be caused, for
example:
by wearing clothing made from synthetic
R
fibers
due to friction between clothing and seats
R
if you push or pull the battery across the
R
carpet or other synthetic materials
if you wipe the battery with a cloth
R
G WARNING
During the charging process, a battery
produces 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
contact with vehicle parts.
Never place metal objects or tools on a
R
battery.
It is important that you observe the
R
described 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
disconnecting the jumper cables.
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 the skin, eyes or clothing.
Do not inhale any battery gases. Do not lean
over the battery. Keep children away from
batteries. Wash battery acid immediately with
water and seek medical attention.
H
Environmental note
Batteries contain dangerous
substances. It is against the
law to dispose of them with
the household rubbish. They
must be collected separately
and recycled to protect the
environment.
Dispose of batteries in an
environmentally friendly
manner. Take discharged
batteries to a qualified
specialist workshop or a
