Important safety notes

Special tools and expert knowledge are
required when working on the battery, e.g.
removal and installation. You should there-
fore have all work involving the battery car-
ried out at a qualified specialist workshop.
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 sys-
tem, 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 inci-
dent, contact a qualified specialist workshop
immediately. Do not drive any further. You
should have all work involving the battery car-
ried out at a qualified specialist workshop.

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.

page 77).
Y
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

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 jumper cables.
Never connect or disconnect the battery
R
terminals while the engine is running.
