Battery (vehicle)
12 V battery – important safety notes
Special tools and expert knowledge are requiredwhen working on the battery, e.g. removal andinstallation. You should therefore have all workinvolving the battery carried out at a qualifiedspecialist workshop.
GWARNING
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:
Rwhen braking
Rin the event of abrupt steering maneuvers
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.
For further information about ABS and ESP®,see (Ypage 65) and (Ypage 68).
All vehicles except vehicles with a lithium-ion battery:
GWARNING
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 forms whencharging the battery as well as when jump-start-ing.
Always make sure that neither you nor the bat-tery is electrostatically charged. A build-up ofelectrostatic charge can be caused, for exam-ple:
Rby wearing clothing made from syntheticfibers
Rdue to friction between clothing and seats
Rif you push or pull the battery across the car-pet or other synthetic materials
Rif you rub the battery with a cloth
GWARNING
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.
