Important safety notes
Work on the battery, e.g. removing or fitting,
requires specialist knowledge and the use of
special tools. Therefore, always have work on
the battery carried out at a qualified specialist
workshop.

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, the ABS (anti-lock braking system) or the
®
ESP (Electronic Stability Program). The oper-
ating safety of your vehicle may be restricted.
You could lose control of the vehicle, for
example:
when braking
R
in the event of abrupt steering manoeuvres
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. Always
have work on the battery carried out at a
qualified specialist workshop.
Further information about ABS (
®
ESP ( page 72).

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.
The highly flammable gas mixture is created
while the battery is charging and when jump-
starting.
Always make sure that neither you nor the bat-
tery is electrostatically charged. Electrostatic
charge is created, for example:
by wearing synthetic-fibre clothing
R
by friction between clothing and the seat
R
if you pull or push the battery across carpet or
R
other synthetic materials
if you rub the battery with a cloth

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.
