Observe the following notes if you want to
replace the battery yourself:
Always replace a faulty battery with a battery
R

The vehicle is equipped with an AGM technol‐
ogy battery (Absorbent Glass Mat). Full vehi‐
cle functionality is only guaranteed with an
AGM battery. For safety reasons, Mercedes-
Benz recommends that you only use batter‐
ies which have been tested and approved for
your vehicle by Mercedes-Benz.
Use detachable parts such as vent hoses,
R
elbow fittings or terminal covers from the
battery which is to be 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.
