Mercedes-Benz recommends that you have the
12 V battery replaced at a qualified specialist
workshop, e.g. at a Mercedes-Benz Service
Centre.
Observe the following notes if you want to replace
the battery yourself:
Always replace a faulty battery with a battery
R
which meets the specific vehicle require-
ments.
The vehicle is equipped with an AGM technol-
3 and
ogy battery (Absorbent Glass Mat) or a lith-
ium-ion battery. Full vehicle functionality is
only guaranteed with an AGM battery or lith-
ium-ion battery. For safety reasons, Mercedes-
Benz recommends that you only use batteries
which have been tested and approved for your
vehicle by Mercedes-Benz.
Carry over detachable parts, such as vent
R
hoses, elbow fittings or terminal covers from
the battery being replaced.
Make sure that the vent hose is always con-
R
nected to the original opening on the side of
the battery.
Fit any existing or supplied cell caps.
Otherwise, gases or battery acid could
escape.
Make sure that detachable parts are recon-
R
nected in the same way.
