Forch arging stations without a preinstal-
led charging cable:
R For saf etyre asons, only use charging
cables that ha vebeen tested and
appro vedby the manufacturer for
ch arging the high-voltage battery in
an electric vehicle.
R Never use damaged charging cables.
R Do not extend thech arging cable.
R Do not use adap ters. #
Make sure toobser vethe saf ety in form a-
tion on thech arging station. Most
charging stations must be activated before
th ech arging process, e.g. using an RFID card.
Obser vethe on-site operator's inst ructions forthe
ch arging station.
The amount of ene rgy dispensed forth ech arging
process, shown bythech arging station, may be
higher than the amount of energy actually absor-
bed bythe high-voltage batter y.This is there sult
of di.erent le vels of charging losses and is descri-
bed as rech arge e1ciency. Charging losses occur,
fo rex ample, due toheat that builds up when ch
arging or from auxiliary consumers that are
switched on. Further information on rech arge e1-
ciency can be obtained at a quali/ed specialist
wo rkshop. Se

Make sure that theex tern al mains supply
has been designed tohandle the set

If necessar y,reduce the set charging

For saf etyre asons, only use thech arging
cable supplied with theve hicle or an
original Mercedes-Benz charging cable.
Mercedes-Benz thoroughly tests these
original charging cables forth eir suitabil-
ity for high-voltage charging of your vehi- cle. Pur
chase these parts at a Mercedes-

may exceed the permitted value forth at countr y.
When abroad, obser vethe count ry-speci/c la ws
when charging. If you ha vequestions concerning
setting thech arging cur rent or if there is a mal-

GER Risk of death when charging at a
damaged soc ket
The charging process uses high voltage.
If th ech arging cable, theve hicle soc ket or the
mains soc ket are damaged, you could receive
an elect ric shoc k. #
Only use an undamaged charging cable. #
Avoid mechanical damage such as crush-
ing, abrading or driving overth e cable. #
Have a damaged vehicle soc ketre placed
at a quali/ed specialist workshop as
soon as possible. #
Never connect thech arging cable to a
damaged vehicle soc ket. *

TE Damage totheve hicle due toove r-
vo ltage in the mains supply The
vehicle is equipped with an elect rical fuse
which pr otects it against overvoltage in the
mains suppl y.This electrical fuse may trip dur- ing se
vere thunderstorms, forex ample, and
may cause the fuse in the building totrip or
may inter rupt thech arging process. These
functions pr otect theve hicle.
ATer the fuse in the building is switched on
again, thech arging process resumes automat-
icall y.
Fo llowing an inter ruption in the po wer supply
without the fuse in the building being tripped,
it may take up to te n minutes forch arging to
re sume automaticall y. *

TE Damage due toove rheating of
ch arging cable and charging cable con-
nector During
thech arging process, thech arging
cable and charging cable connector can heat
up within their permissible limit values.
The permissible limit values are in0uenced by
th efo llowing factors:
