Mercedes-Benz recommends that you have the
12 V battery replaced at a qualified specialist
workshop, e.g. at an authorized Mercedes-Benz
Center.
Observe the following notes if you want to replace
the battery yourself:
Always replace a faulty battery with a battery
R
that meets the specific vehicle requirements.
The vehicle is equipped with a battery using
AGM (Absorbent Glass Mat) technology or a
lithium-ion battery. Full vehicle functionality is
guaranteed only with an AGM battery or lith-
ium-ion battery. For safety reasons, Mercedes-
Benz recommends that you use only batteries
that have been tested and approved for your
vehicle by Mercedes-Benz.
Carry over detachable parts, such as vent
R
hoses, elbow fitting 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.
Install 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.
