Observe the notes on the 12 V battery

page 394).
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:
R
Always replace a faulty battery with a battery
which meets the specific vehicle require‐
ments.
The vehicle is equipped with an AGM technol‐
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.
R
Carry over detachable parts, such as vent
hoses, elbow fittings or terminal covers, from
the battery being replaced.
R
Make sure that the vent hose is always con‐
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.
R
Make sure that detachable parts are recon‐
nected in the same way.

Permitted towing methods

ognise dangers.

vehicle in the case of a breakdown, rather than

axles on the ground. Do not use tow bar sys‐
tems.
