Mercedes-Benz recommends that you have the
starter battery replaced at a qualified specialist
workshop, e.g. an authorized Mercedes-Benz Cen-
ter.
If you want to replace the battery yourself, observe
the following information:
R
Only replace a faulty battery with a battery
which fulfills the vehicle's specific require-
ments.
R
Carry over detachable parts such as the vent
hose or terminal cover from the battery which
is to be replaced.
R
Make sure that the vent hose is always con-
nected to its original opening on the battery
side.
Install the existing or newly supplied stop
plugs.
Otherwise, gases or battery acid could escape.
R
Make sure that the detachable parts are con-
nected in the same way as before.
For safety reasons, Mercedes-Benz recommends
that you only use batteries that have been tested
and approved for your vehicle by Mercedes-Benz.
These batteries provide increased impact protec-
tion to prevent vehicle occupants from suffering
acid burns should the battery be damaged in an
accident.
&
WARNING Risk of explosion due to elec-
trostatic charge
Electrostatic charge can ignite the highly explo-
sive gas mixture in the battery.
#
To discharge any electrostatic charge
that may have built up, touch the metal
vehicle body before handling the battery.
The highly flammable gas mixture is created while
the battery is charging and when jump-starting.
&
WARNING Danger of chemical burns from
the battery acid
Battery acid is caustic.
#
Avoid contact with the skin, eyes or
clothing.
